The Lightweight Cars Competitors And Their Structures Engineering Essay

The Lightweight Cars Competitors And Their Structures Engineering Essay The Atom prototype chassis was tested to determine the value of its global torsional stiffness. This value was calculated to be 1330Nm/deg. This value was to be improved upon by the following method: The creation of a Finite Element baseline validation model using MSC Patran/Nastran software compared favourably with the physical test results with a torsional stiffness value of 1352Nm/deg for a mass of 47 Kg and an efficiency of 88g/Nm/deg. The discussed modifications had been suggested to Atom upon initial appraisal of the chassis were incorporated into this baseline model and resulted in increases in both torsional stiffness and efficiency. Further, the design improvement study performed resulted in a maximum torsional stiffness of 6448Nm/deg, an increase of 377% over the baseline model. A maximum increase in efficiency of 286% to 23g/Nm/deg for a mass of 148.3Kg accompanied this increase in torsional stiffness. Following optimisation of the model to gain minimum mass for a stiffness of 6000Nm/deg a torsional stiffness of 6030Nm/deg was realised for a mass of 127Kg, giving an increase in efficiency of 322% over the baseline model to 20.99g/Nm/deg. ACKNOLEDGMENTS First, I would like to thank my parents for their support and encouragement throughout my university career. I would like to sincerely thank my supervisor Mr. Mike Dickison for his continual support and enthusiasm for this thesis. Thanks to Brunthinthorpe Car Ltd for providing a very interesting design project and great support throughout. Finally, a special thanks to all my friends at Coventry who have made this such a great year. INTRODUCTION 1.1 Bruntingthorpe Sports Cars Ltd Bruntingthorpe Sports Cars Ltd has been involved in the Lightweight car industry for a number of years. They have produced work for many other companies. 1.2 Aims of Project The purpose of the design project: To perform a torsion test on the prototype chassis to determine its torsional stiffness; To create a finite element model of the chassis; To incorporate a design improvement study and note the effects on the global torsional stiffness of the chassis; To attempt an optimisation for maximum efficiency. The following limitations are given for this project: The body shape is fixed and therefore the overall external shape of the chassis must not be altered; Overview of Chassis Types Definition of a Chassis The chassis is the framework to which everything is attached in a vehicle. In a modern vehicle, it is expected to fulfil the following functions: Provide mounting points for the suspensions, the steering mechanism, the engine and gearbox, the final drive, the fuel tank and the seating for the occupants; Provide rigidity for accurate handling; Protect the occupants against external impact. While fulfilling these functions, the chassis should be light enough to reduce inertia and offer satisfactory performance. It should also be tough enough to resist fatigue loads that are produced due to the interaction between the driver, the engine and power transmission and the road. Ladder frame The history of the ladder frame chassis dates back to the times of the horse drawn carriage. It was used for the construction of body on chassis vehicles, which meant a separately constructed body was mounted on a rolling chassis. The chassis consisted of two parallel beams mounted down each side of the car where the front and rear axles were leaf sprung beam axles. The beams were mainly channel sections with lateral cross members, hence the name. The main factor influencing the design was resistance to bending but there was no consideration of torsional stiffness. A ladder frame acts as a grillage structure with the beams resisting the shear forces and bending loads. To increase the torsional stiffness of the ladder chassis cruciform bracing was added in the 1930s. The torque in the chassis is reacted by placing the cruciform members in bending, although the connections between the beams and the cruciform must be rigid. Ladder frames were used in car construction until the 1950s but in racing only until the mid 1930s . A typical ladder frame is shown below. ladder Fig. 1 [Ref. 2] Twin tube The ladder frame chassis became obsolete in the mid 1930s with the advent of all-round independent suspension, pioneered by Mercedes Benz and Auto Union. The suspension was unable to operate effectively due to the lack of torsional stiffness. The ladder frame was modified to overcome these failings by making the side rails deeper and boxing them. A closed section has approximately one thousand times the torsional stiffness of an open section. Mercedes initially chose rectangular section, later switching to oval section, which has high torsional stiffness and high bending stiffness due to increased section depth, while Auto Union used tubular section. The original Mercedes design was further improved by mounting the cross members through the side rails and welding on both sides. The efficiency of twin tube chassis is usually low due to the weight of the large tubes. They were still in use into the 1950s, the 1958 Lister-Jaguar being an example of this type . Fig. 2 [Ref. 2] Four tube As designers sought to improve the bending stiffness of a chassis, the twin tube chassis evolved into the four tube chassis. The original twin tube design was modified by adding two more longitudinal tubes that ran from the front of the car, around the cockpit opening and on to the rear of the car. The top and bottom side rails are connected by vertical or diagonal members, essentially creating a very deep side rail and thus improving the bending characteristics. The two sides are joined by a series of bulkheads, normally located at the front, footwells, dash area, seatback, and rear of the chassis. A significant increase in bending stiffness was realised but there is little increase in the torsional stiffness due to the lack of triangulation causing lozenge of the bays. lotus21formula1_1961 Fig. 3 Lotus 21 [Ref. 4] Backbone The backbone chassis has a long history in automobile design with its origins credited to Hans Ledwinka, an engineer with Czech automaker Tatra. Ferdinand Porsche worked with Ledwinka in the 1920s and arguably learned much of his craft from him. When a chassis derives its torsional stiffness from one large central tube running the length of the car, the resistance to twist depends almost entirely on the cross-sectional area of that tube. Clearly, that cross section can be much larger than the typical drive shaft tunnel. Depending on the vehicle configuration it is possible to arrange for an approximately rectangular tube of substantial dimensions. This arrangement fits in well with conventional side-by-side seating, with the large central spine forming a centre console. Such an arrangement was utilised by Colin Chapman on the Lotus Elan . backbone_elan_1962 Fig. 4 1962 Lotus Elan backbone chassis [Ref.4] Spaceframe Although the spaceframe demonstrated a logical development of the four-tube chassis, the space frame differs in several key areas and offers enormous advantages over its predecessors. A spaceframe is one in which many straight tubes are arranged so that the loads experienced all act in either tension or compression. This is a major advantage, since none of the tubes are subject to a bending load. Since space frames are inherently stiff in torsion, very little material is needed so they can be lightweight. The growing realisation of the need for increased chassis torsional stiffness in the years following World War II led to the space frame, or a variation of it, becoming universal among European road race cars following its appearance on both the Lotus Mk IV and the Mercedes 300 SL in 1952. While these cars were not strictly the first to use space frames, they were widely successful, and the attention they received popularised the idea. lotusmarkVI_1952 Fig. 5 1952 Lotus Mk.IV spaceframe Stressed skin The next logical step for chassis development was the stressed skin design. This is more difficult to construct than a spaceframe with the accurate folding, forming, drilling and riveting of sheet steel or modern composite materials. The lessons learnt in the aircraft industry do not usually apply directly in automotive practice. The loads on aircraft are widely distributed the lift that holds a plane up, for example, is spread over the entire area of its wings. On a race/sports car, the loads are much more concentrated, being focused on the suspension mounting points. Even when a method is developed to accept forces and spread them over a load bearing skin, it becomes extremely inconvenient to make any modifications and may even require a major redesign. Analysis of the stresses in stressed skin construction is more difficult. The continuous surface considerably complicates access for repair or replacement of the cars mechanical components. This may also explain why stressed skin construction was virtually unheard of in race cars before the modern mid-engine configuration. The majority of mid-engine race cars end their stressed skin construction at the back of the cockpit, with either a space frame or the engine itself forming the remainder of the structure. For all these drawbacks, stressed skin construction can potentially outperform any other form of race car construction in terms of torsional stiffness. Load Cases A chassis is subjected to three load cases: bending, torsion and dynamic loads. The bending (vertical symmetrical) load case occurs when both wheels on one axle of the vehicle encounter a symmetrical bump simultaneously. The suspension on this axle is displaced, and the compression of the springs causes an upward force on the suspension mounting points. This applies a bending moment to the chassis about a lateral axis. bending Fig. 6 Bending Load case [Ref. 2] The torsion (vertical asymmetric) load case occurs when one wheel on an axle strikes a bump. This loads the chassis in torsion as well as bending. It has been found both in theory and in practice that torsion is a more severe load case than bending. torsion2 Fig. 7 Torsion Load case [Ref. 2] The dynamic load case comprises longitudinal and lateral loads during acceleration, braking and cornering. These loads are usually ignored when analysing structural performance. A torsionally stiff chassis offers a number of advantages: According to vehicle dynamics principles for predictable and safe handling the geometry of the suspension and steering must remain as designed. For instance the camber, castor and toe angles could change with torsional twist or the steering geometry could change causing bump steer. Once again according to vehicle dynamics principles a suspension should be stiff and well damped to obtain good handling. To this end the front suspension, chassis and the rear suspension can be seen as three springs in series as shown in Fig. 8. If the chassis is not sufficiently stiff in torsion then any advantages gained by stiff suspension will be lost. Furthermore, a chassis without adequate stiffness can make the suspension and handling unpredictable, as it acts as an undamped spring. Rear Suspension Front Suspension Chassis Fig. 8 Chassis and suspension as springs Movement of the chassis can also cause squeaks and rattles, which are unacceptable in modern vehicles. Simple Structural Surfaces: The simple structural surfaces method SSS originated from the work of Pawlowski and is described in the notes by Brown and the book by Brown, Robertson and Serpento. These references should be consulted for a thorough understanding of this approach. The SSS method provides a simple way of determining load paths through a structure. Each surface is assumed only to have in-plane stiffness and no out-of-plane stiffness. Each surface is acted on by forces, e.g. the engine mounts. For equilibrium, adjacent surfaces must provide reactions. This process is continued throughout the structure and determines the load on each SSS. It can then be realised if an SSS has insufficient supports or reactions and therefore determines the continuity of load paths and the structures overall integrity. ssssss Fig. 9 [Ref. 2] Fig. 10 [Ref. 2] As can be seen in the SSS example in Fig. 9 the box structure is loaded in torsion by the moment Ms, which causes the shear forces Q1 and Q3. All the surfaces are in complementary shear, and the structure is stiff in torsion. If one shear surface is removed, none of the complementary shear forces can exist. The torsion load is then transferred to the floor of the box via the edge forces Q, so the floor panel is loaded out of plane rather than in complementary shear The Lightweight cars competitors and their structures Atom Car Atom car is a brilliant example of the lightweight sports car philosophy. You strip out all the heavy crap that sits in the big fat sports cars, put in a small, light but powerful engine, and you have something you can have tremendous fun in. The Atom, like its fellow lightweights the Caterhams and the Elises, delivers high thrills for low costs. This is a brilliant weekend car, a trackday car, that you can go very fast in very easily. And I like doing that (on the track obviously) which is why this takes my third and final garage space. Ariel Atom 500 V8 built to celebrate 10th birthday To mark the occasion, Ariel employees assembled an example of their upcoming Ariel Atom 500 V8 high performance car in a personal record of five hours, fifteen minutes. The Ariel Atom 500 V8 is a highly-anticipated ultra light-weight sports car that has been in the making for around two years. The car, although its not your conventional car perse, is more of a superbike with four wheels. Ariel has confirmed the car will use a 500 horsepower thats 373kW V8 in the car that will weigh around 500kg. With a superbike like power-to-weight, the Ariel Atom 500 V8 is sure to be the scariest car ever to hit the market. The engine will be a 32-valve Hartley 3.0 -litre V8 which was derived from merging two Suzuki Hayabusa 1300cc superbike four-cylinder engines together. The engine is said to spin to 16,500rpm, like a superbike. And with a gearbox that allows flat-shifting, like a superbike, Ariel says the car will easily achieve 0-160km/h in under six seconds and go on to a top speed of 270km/ hà ¢Ã¢â€š ¬Ã‚ ¦ like a superbike. In a recent Autocar report, Atom designer Simon Saunders summed up the Atom 500 V8 build in a few words, The GT-R is the daily driven car that performs excellent everywhere. The Zonda F is the supercar for the long exploration trips through Europe. The Atom is the little insane car for scaring the crap out of yourself LOTUS EVORN: http://www.blogcdn.com/green.autoblog.com/media/2008/09/evora-chassis.jpg Lotus is increasingly building on its 60 year history of creating more with less with all its recent efforts on electric and hybrid drive cars. Besides the power train work, Lotus has plenty of experience with lightweight structures. The latest evolution of that is the architecture of the new Evora sports car that debuted at the London Motor Show this summer. Lotus has now won an award for the aluminium chassis of the Evora at the Aluminium 2008 trade fair at Messe Essen in Germany. The Lotus architecture is comprised mainly of aluminium extrusions combined with some casting. The components are in part riveted together but are primarily joined by adhesive bonding. Lotus developed much of the technology while creating the Elise and has created structures with greater strength and lower weight. With the combination of aluminium structures and the expertise that Lotus also has in advanced composites, car makers can tap into a lot of technology to help reduce weight and improve fuel effi ciency. Lotus provides an automotive structure with a unique approach. They combined adhesive bonding techniques with mechanical joining, resulting in innovative and creative solutions. Lotus used their expertise in lightweight materials to complete this structure, achieving a low weight and a high structural stiffness and therefore ensuring a major impact on environmental and sustainable performance. The Lotus Evora demonstrates an accumulation of our core competencies in aluminum and composite body engineering, jointing techniques and vehicle systems integration. Lotus pioneered the technology of bonded aluminum extrusions for use in road vehicles and has successfully developed high performance cars for other car companies around the world. One great advantage of our low volume vehicle architecture technology is that it can be used by one car manufacturer looking to develop a range of niche products, or by a group of car manufacturers looking to share investment, but still retain a high de gree of end product separation. The Evoras chassis is an evolution of the Lotus vehicle architecture from the Lotus aluminum crossover concept vehicle previously showcased at the Geneva Motor show, and allows for the development of a range of vehicles up to a gross vehicle weight of 1,900 kg. This architecture has been designed to be more applicable to mid-volume applications by utilizing low capital investment manufacturing processes. The Evora structure progresses the Lotus bonded and riveted technology used in the Elise family of vehicles with unique extrusions and folded panels, whilst providing contemporary ease of ingress/egress, build modularity and improved, lower cost repairs. The Lotus Evora employs a composite roof as a stressed structural member to give an exceptional vehicle stiffness of 26,000 Nm per degree, thanks in part to the seatbelt anchorage frames secondary function as a roll over structure, and partly because the high-tech composite body panels are stressed it ems. However, despite this high stiffness, the complete chassis and modules weigh just 200 kg (prototype weight), helping to keep the weight of the whole car to just 1350 kg (prototype weight). To deliver this high performance structure, bonded and riveted high grade aluminum extrusions and simple, elegant folded sheet elements are used in the lower structure, which complements the stressed composite roof upper structure. Attached to the high strength central tub are sacrificial energy absorbing sub frames of extruded aluminum at the front and lightweight welded steel at the rear. These sub frame modules also offer advantages in terms of convenience and low cost of repair, and during manufacturing can be brought to the production line fully assembled, ready to be attached to the fully assembled tub. LUSO LM23: Luso Motors is a Portuguese car design and development house which has brought us a lightweight sports car LM 23. This design inspired from the Lotus 23b. The Luso Motors 23 is powered by a 150-horsepower 1.0-litre Honda CBR1000 engine, is mated to a six-speed sequential transmission. According to LusoMotors founder Ernesto Freitas says customers can choose a number of different engines, including a Subaru turbo boxer. This sport car features a steel tube frame chassis, double skin aluminium alloy sheets, riveted and glued with inner foam reinforcements, the outer skin is made out of fibreglass and carbon fibre components. It weighs just 881 pounds, a lightweight sports car, and 150 hp! The car will start at à ¢Ã¢â‚¬Å¡Ã‚ ¬15,000(about $23,600). Deronda G400: (http://www.sportscarzone.com/deronda-g400-a-race-bred-exotic-sports-car/) Close your eyes and build the ultimate two-seat sports car. Start with a lightweight, tube-frame chassis and then add race-bred suspension and oversized brakes. Wrap the vehicle in an aero-inspired carbon fiber body shell, but keep the generous cockpit open for wind-in-your-hair enjoyment. Lastly, wedge a huge, torque-laden, tire-shredding engine into the middle of the chassis, and tune the exhaust note so it scares the gophers out of your neighbors front lawn. Now, open your eyes and take a look at the Deronda G400. We recently had an afternoon with this exceptional hand-built brute in the mountains above Malibu. With a mid-mounted V8 sourced from a Chevrolet Corvette and the curb weight of a Smart fortwo, the Deronda seems powerful enough to move the economy. Whats the story behind the car? Who makes it, and how? Most importantly, can the Deronda be tamed? Read our full adventure after the jump. The Deronda was originally developed in the United Kingdom by Andy Round, a successful aeronautical engineer. Round wanted to purchase a lightweight high-performance road car, but was frustrated and dissatisfied with what he found after looking at offerings from Caterham, Ultima and Westfield. In a bold move, Round decided to build his own sports car using the most advanced components and materials he could get his hands on. Driving dynamics and safety were key priorities, while styling was to be influenced by Formula 1 and Le Mans Series race cars. The first prototype, manufactured by Fabrication Techniques, was called the Deronda F400. Powered by a turbocharged Audi 1.8-liter four-cylinder rated at 210 hp, Rounds new open-cockpit sports car made its debut at the 2004 Auto sport International Racing Car Show in the UK. At this point, Auto sport Development, a North American manufacturer and importer of unique street and race cars, was sufficiently impressed with the engineering and design of the Deronda that it wanted to build it. Discussions ensued, and the company licensed the rights to build and sell the car on this continent. Before production started, the team of engineers at Auto sport made a few changes in order to appeal to American drivers. The small 1.8-liter Audi engine was dropped, and a Corvette-sourced 6.0-liter V-8 took its place. To accommodate the much larger power plant, the team stretched the wheelbase by five inches (increasing overall length by eight inches). The brakes were upgraded, and the suspension was modified to accept the new running gear. The finished product was called the Deronda G400. Available directly from Sirius Motorsports, it is sold turn-key and according to the company, it is 50-state street legal (when licensed as a component car). Each Deronda begins as a pile of two-inch diameter (.095 wall) 4130 chromium molybdenum tubes. Stronger and more durable than standard 1020 steel, chrome moly is steel that has been alloyed with small amounts of chromium and molybdenum to increase its strength. The tubing is precisely cut and placed on a large jig where it is TIG-welded by hand. Safety is principal, so the frame is engineered with double side-impact protection tubing, and double rollover hoops (four in total). Crash structures are built into the front and rear for additional occupant protection. Once complete, the intricate frame weighs 650 pounds bare. A custom suspension, comprised of unequal-length control arms with horizontal mounted shocks, is bolted to the rigid platform. Massive cross-drilled Baer rotors are installed with dual-piston caliper Corvette C5 brakes up front (CNC-milled with the Deronda logo) and single-piston C5 calipers on the rear. Aluminum alloy front wheels measure 18ÃÆ'-9-inches (wearing 235/30R18 rubber), while the rears measure 18ÃÆ'-10-inches (with 285/35R18 tires). Placed mid-engine in the chassis is a new 6.0-liter LS2 engine (as used in the Corvette C6), mated to a durable Porsche G50 five-speed transaxle, with power delivered to the rear wheels. With stock headers, and environmentally-friendly catalytic converters, the engine is rated at 400 hp and 400 lb-ft of torque. A 14-gallon foam-filled ATL fuel cell keeps the power plant fed, and increases safety (a tank-fed fire-suppression system is optional). The exhaust is fitted with a muffler, but it still lets plenty of the engines anger out the back end. The skin of each Deronda is comprised of a mixture of fiberglass and carbon fiber body panels. The head rest, dashboard, rear wing, and fenders are all carbon fiber. Twin minimally-padded fiberglass seats with six-point harnesses are installed, and the windshield is DOT-legal single-piece of laminated glass with a windshield wiper. The entire build process, from tubing to a finished vehicle, takes about eight weeks. The final curb weight is a mere 1,890 pounds. Simple, yet functional, is the best way to describe the cabin. The dashboard presents only the most critical information. While the vehicle obviously lacks doors and a roof, heat arrives from air spilled around the front-mounted radiator. Small vents, not unlike ports found on light private aircraft, are able to bleed fresh air into the foot wells. Modeled with dimensions similar to the Porsche 996, the cockpit is accommodating even for someone who is 62à ¢Ã¢â€š ¬Ã‚ ³ tall or taller. The seats and pedals are both adjustable for a custom fit to accommodate nearly everyone. After a perplexing process of flipping switches and pushing buttons, the brawny V8 spins to life and settles to a smooth idle. Stock Corvette headers dump hot gasses into the cats before they are expelled out twin howitzer-looking mufflers. The sound that penetrates the air is a deep irate rumble that will send chills up your spine. With the clutch fully depressed, we slip the milled aluminum shifter into first gear and slowly release the clutch. Without drama, we pull away. Lacking power steering, the small, flat-bottomed Sparco steering wheel is very heavy at low speeds. The driveway to the main road is steep, but the needle nose of the Deronda offers surprisingly generous ground clearance. As the traffic breaks, we pull into traffic pointing the car down Californias famed Mulholland Drive towards the Santa Monica Mountains. Warned about the power under our right foot, we treat the gas pedal as if it were a made from blown glass we dont need to spin this vehicle just outside the gate. With the road clear, we goose the accelerator. It is immediately apparent that this could be the quickest car weve ever driven. The engine spools to the called-for throttle input as if the transmission is in neutral, yet the car is firmly in gear. A light touch on the gas pedal is met by the white needles on the primary gauges rapidly sprinting clockwise around their dials. Behind you, the roar of the LS2 seems to scorch the pavement like the DeLorean in Back to the Future. Gearing doesnt seem to have much effect on the acceleration, either. Whether the transmission is engaged in second or fifth gear, 400 lb.-ft. of torque propels the lightweight G400 as if it were being launched from a 12-gauge shotgun. On public roads, with the wheels wrapped in street tires, the Deronda is seriously challenged for grip (the car is equipped with an adjustable electronic traction control that can be completely defeated). The wide Toyo Proxes T1R rubber on the rears immediately spins under full throttle initiating the electronic reigns, so we simply avoid the last 40% of the accelerators travel. Even driven at only 6/10ths, the car offers more power than nearly everything else on the road. The company doesnt have cited official 0-60 mph times, but under the right conditions were sure its comfortably in the low three-second range. Deronda says the G400 runs out of gears at an ample 183 mph well above the top ends of most minimalist competitors. Redline is a tick under 6,000 rpm, but you simply dont need to go there. The car pulls all the time, regardless of the engine speed or gear. Lug it around town in fourth at 1,200 rpm and it will deliver enough torque to annihilate the random Subaru WRX that begs to race. For all of its power, the engine is surprisingly tractable and easy to control. Drive it gently, and you flow with the traffic without concern. Step on the gas and the Deronda growls before it rips your head off. Rarely do you find a car with a bite that so exactly matches its bark. Blinding acceleration aside, the overall impression is that the Deronda drives much more like a race car than a street car. Without power assisted steering or brakes, the primary controls feel much heavier that those on any high performance road vehicle. Both hands, and both feet, are constantly interacting with the wheel, clutch, brake, and accelerator. Involving would be a supreme understatement. derondafd 02 opt Deronda G400 A race bred exotic sports car! After time spent following the roads curving through the mountains, we became much more comfortable in the Deronda. Excellent front visibility allows the driver to precisely place the wheels exactly where intended. While the steering was a chore at low speeds, the effort eased as our velocity increased. The lack of assist soon becomes an asset as the steering feels quick, accurate and very direct. Our insatiable appetite for the accelerator pedal kept us off the brakes, but eventually traffic forced us to call them to duty. As our speeds were relatively low (50-70 mph in the canyons), we couldnt get a lot of heat into the pad compound. The initial application of the pedal seemed futile as the drilled rotors continued to slide between the pads. Only when our foot really got on it hard did the Corvette-sourced stoppers feel strong. This car is fitted with generous rotors and track-ready pads, but it was clear we were underutilizing them. It also needed softer street pads (while there is a cockpit-adjustable brake-bias knob, we didnt touch it). Open to the world, the cabin was surprisingly comfortable at speed. The driver and passenger sit low in the chassis, and the large, canopy-like windscreen does an excellent job deflecting the slip stream around the cockpit. It was cool outside, but we could feel some warm air spilling into the foot wells. Rearward visibility was poor, even through the tunnel-vision exterior mirrors, and all you can see is the jet-black carbon fiber wing (visibility really didnt matter, as nobody passed us). However, even though the Deronda is smaller than most of the other traffic on the road, we never had an overbearing feeling of being undersized. Quite the opposite, actually, as the incredible power delivery and nimble handling made us feel as confident in traffic as a squirrel running from a small child. We never tired of darting through the canyons in the needle-nose Deronda. In fact, we felt like a fighter pilot. Our forward view was through a large glass canopy, we were strapped down with thick shoulder harnesses, and the engines loud roar filled the void left by our wake. Like a jet, the G400 is agile, powerful, and built for speed. Without a doubt, a prepared Deronda would dominate most conventional sports cars on a race track a thought that has already crossed the minds of the team at Autosport Development. With a safe, strong, and proven chassis already developed, a closed -cockpit monocoque body for the platform wouldnt be too much of a stretch. We wouldnt be surprised to see something rolling out of the factory in the near future wearing competition attire. derondafd 13 opt Deronda G400 A race bred exotic sports car!

Old Man And The Sea Summary Essay -- essays research papers

The Old Man and the Sea by Ernest Hemingway (1899 - 1961) Type of Work: Symbolic drama Setting North Coast of Cuba; early twentieth century Principal Characters Santiago, an old, weathered fisherman Manolin , a boy, Santiago's young fishing companion The Marlin, a gigantic fish Story Overveiw Eighty-four days had passed since Santiago, the old fisherman, had caught a fish, and he was forced to suffer not only the ridicule of younger fishermen, but near-starvation as well. Moreover, Santiago had lost his young companion, a boy named Manolin, whose father had ordered him to leave Santiago in order to work with more successful seamen. But the devoted child still loved Santiago, and each day brought food and bait to his shack, where they indulged in their favorite pastime: talking about the American baseball leagues. The old man's hero was the New York Yankees' Joe DiMaggio. Santiago identified with the ballplayer's skill and discipline, and declared he would like to take the great DiMaggio fishing some time. After visiting one particular afternoon, the boy left Santiago, who fell asleep. Lions immediately filled his dreams. As a boy he had sailed to Africa and had seen lions on the beaches. Now, as an old man, he constantly dreamed of the great and noble beasts. He no longer dreamed of storms, nor of women, nor of Great occurrences, nor of great fish, nor fights nor contests of strength, nor of his wife. He only dreamed of places now and of the lions on the beach ... He loved them as he loved the boy. Before dawn of the next day, the fisherman, as usual, hauled his salt-encrusted skiff onto the beach and set out by himself. But today, in hopes of breaking his unlucky streak, he was determined to sail into deep waters, out much farther than the other anglers would go. He followed the sea birds and flying fish; they would tell him b y their movements where the fish congregated. He watched the turtles swimming near his boat. He loved the turtles, "with their elegance and speed... " Most people are Heartless about turtles because a turtle's heart will beat for hours after he has been cut tip and butchered. The old man thought, I have such a heart too ... Early on, Santiago managed to land a tenpound tuna. Thinking this a good omen, he used the fresh meat to bait one of his lines. By n... ...ng manly courage, endurance, and noble suffering. In fact, the novel would be little more than an adventure story were it not for Santiago's dialogues with himself - his repetitive and symbolic musings, daydreams and plottings. Unlike other fishermen, who see the ocean merely in terms of economic gain, Santiago looks on the sea and its inhabitants with love and respect. Notably, he prefers to call the sea "la mar," its feminine form, rather than the harsher, masculine "el mar." Some readers may see Christian symbolism in the story: Santiago means St. James in Spanish; the battle with the fish lasts three days; Santiago, arriving at the shore, carries his mast, like a cross, on his shoulders, and, like the biblical Christ, stumbles under its load. Later, the fisherman lies down exhausted on the floor of his hut with his arms stretched out stiffly and the palms of his hands up. But the giant fish - representing the hopes and dreams of mankind - and the old man's relationship with it, is what creates the extraordinary pathos of the novel. And, in the end, even Santiago's (humankind's) modest expectations are snatched from his grasp.

Business Context And Strategic Environment Essay

In the modern business arena, stiff competition has made many companies to diversify their product line in order to retain the existing customers and attract new ones. In addition, firms have established strong ties with their customers through effective fulfillment of ethical and social obligations. This has not only resulted to high profits for such companies but it has also enhanced strong customers’ loyalty and good image to both the government and the general public. This paper keenly discusses the ways in which Easy Jet, an airline company based in London fulfils its ethical and social obligations. Easy Jet Company is a major airline company in Britain which is known for its large number of routes and high number of passengers. With more than 500 routes the company is able to effectively carry its passengers to different regions including North Africa, West Asian and in European countries. One of the major reason as to why Easy Jet Company has been performing well in the market is due to the application of the acquisition strategy. By acquiring other smaller companies, Easy Jet Company has been able to widen its customer’s base leading to higher profits. Ethically the company has been in the fore front in ensuring that passengers have been provided with quality services. In order to ensure that passengers are attracted towards the company services, the management team led by Carolyn McCall, the CEO has reduced the prices of its services. This in turn has created a strong positive relationship between the customers and the company (Dunn and Graham, 2007). Environment conservation strategies are other social aspects which Easy Jet Company has effectively established. This is based on the fact that due to its high number of routes, the company aircrafts emits high amount of carbon which is a major cause of global warming. In order to address noise pollution which is also a major challenge facing the company Easy Jet has adopted ICAO which is a strategy aiming at improving their aircrafts and reducing noise. In the same way, the company has undertaken some major strategies in collaboration with other companies in order to reduce environmental pollution. The first strategy is that the company has reduced unnecessary flights. This has been achieved through introduction of point to point technique. This implies that aircrafts will minimize extra routes in order to reduce the level of carbon emitted in the air. In addition, the company has adopted the policy of taking the shortest distance between any two destinations. As a result, the amount of carbon emitted by the Easy Jet aircrafts has drastically reduced leading to environmental benefits. Secondly, the company effectively utilizes its resources and aircrafts. This entails maintaining an average flight time of 1. 9 hours and 20 minutes turn around time. Thirdly, Easy Jet uses the services of new aircrafts in its operations. By retiring old aircrafts and adopting modern ones the company has been able to maintain environmental friendly policies. This has also been achieved through replacement of the aircrafts after every 10 years of operations. Similarly Easy Jet has adopted modern technology which aims at reducing the amount of fuel used and giving information to the cabin crew about the rate of fuel consumption by the aircrafts. Through the introduction of a modern aircraft referred to as A319, the company has been able to reduce the consumption of fuel by 2%. As a way of showing its commitment in conserving environment, Easy Jet greatly contributed in the formation of European Single Sky regulations which are geared towards reduction of negativities brought about by flight delays. The company has also participated in various meeting with other European based companies in order to ensure that air pollution is effectively addressed. Use of modern technology is another factor which has made Easy Jet maintains a high level of professionalism. This involves adoption of paperless office. Through the use of computers and scanners, the hard copy documents are scanned and then disposed. The company has a well maintained recycling facility which ensures that all the papers used are reused and sensitive company information effectively is properly secured. In the same way the company packaging policies ensures that the materials used in packing its products can be easily recycled. In order to ensure that waste materials from the company are at minimal level, the company has emulated products which are not perishable. Easy Jet Corporations has taken various measures in order to fulfill its social obligations. Open office policy is one of the major aspects which have been adopted by the company in order to create an effective interaction between the employees and the senior managers. In turn, this has enhanced high level of motivation among the employees leading to a rise in their level of productivity. Another significant social aspect adopted by Easy Jet is the use of intranet. This has improved the operations of the company in that the employees and other stakeholders have been able to contribute in the decision making process in the company (Jones and Lois 2007). In addition, the use of intranet has enabled the employees and the customers to be informed about the daily and long term operations of the company. In order to make the employees be part of the company, senior managers have provided opportunities through which employees can publish various issue which affects them during their duties. Such issues include technical, costs of operations and employment aspects. Through regular updates via intranet, customers are able to arrange with the company regarding their journeys. Easy Jet social obligations have also been achieved through the use of online chart forum which is initiated monthly in order to create a strong connection between the directors and the employees. In order to supplement the benefits of the intranet within the company, directors have also introduced magazines which have wide range of information regarding the company. Examples of such magazines are Plane times, Cabin fever and The stable approach. Extrinsic motivation of the employees is also an imperative social issue that Easy Jet Company has initiated. This has been achieved by adopting GoMAD rewards scheme whose aim is to recognize and reward the hard working employees (Brignall and Miles, 2006). This has reduced the rate of employees’ turnover leading to more profits and reduced costs of training new employees. In order to ensure that there is no racial segregation within the company, Easy Jet is an equal opportunity employer. This is based on the fact that anyone can apply for a job in the company regardless of the age, disability or sex. As a result the company employees’ fraternity is comprised of people from different backgrounds. Provision of efficient and safe working environment is another fundamental social issue that Easy Jet has initiated. This has produced positive results in the form of increased productivity by the employees and high level of profits for the company. In addition, the interrelationship between the senior managers and other employees has been positive due to the involvement of all the stakeholders in the decision making process. Conclusion Based on the above analysis, it is clear that Easy Jet Company has successfully achieved its ethical and social obligations. The directors have come up with rules which are geared towards maintaining high level of ethics among the employees. These rules includes keeping accurate and full records, keeping all dealing legitimate and refusing bribes from suppliers or customer. The strict following of these rules and environmental conservation policies has made the company attain a competitive edge in the air transport industry.

The Bomb That Saved Millions Essays - Free Essays, Term Papers

The Bomb That Saved Millions Essays - Free Essays, Term Papers The Bomb That Saved Millions The Terror that Saved Millions The atomic bomb and it's use over the two Japanese cities of Hiroshima and Nagasaki is still a source of heated debate even over fifty years later. Many people on both sides -Japan and The United States- hold the belief that Truman's decision to drop the bomb was a mistake and that under no circumstances should such drastic measures be taken in war. What these people do not realize are the far more horrible alternatives than the destruction of just two cities: an invasion of mainland Japan where millions of more deaths would have occurred, Soviet aid resulting in the division of Japan into a communist nation and the destruction of their culture, the deaths of thousands of Allied prisoners of war held in Japan, and the threat of renewed hostilities from Japan not to mention the possibility of several more years of bloody conflict. Throughout the course of this paper all of these examples will be discussed, as well as why Truman's decision was the most humane and rational for all the n ations involved, including Japan. Axis power in Europe was destroyed, Hitler and Mussolini were dead, their armies annihilated, their nation's in ruins, Japan however was not. Though weakened from a near four year long war with the Allies, the Japanese continued fighting, as was their code, to fight to the death, and never surrender. President Harry Truman in the interest of saving both American and Japanese lives from an invasion of mainland Japan, authorized the use atomic bombs against Japan. The first atomic bomb to be used on Japan was composed of uranium. It was dropped on Hiroshima, Japan, on Aug. 6, 1945. The explosion, which had the force of more than 15,000 tons of TNT, instantly and completely devastated 10 square kilometers of the heart of this city of 343,000 inhabitants. Of this number, 66,000 were killed immediately and 69,000 were injured, more than 67 percent of the city's structures were destroyed or damaged. The next atomic bomb to be exploded was of the plutonium type, it was dropped on Nagasaki three days later, producing a blast equal to 21,000 tons of TNT. The terrain and smaller size of Nagasaki reduced destruction of life and property, but nevertheless 39,000 people were killed and 25,000 injured, while 40 percent of the city's structures were destroyed or seriously damaged. Preceding the bombing of Hiroshima the Americans had pledged that if the Japanese did not agree to an unconditional surrender and an immediate conclusion to all hostilities that they would bomb Japan with atomic weapons. The Japanese called the Americans on a bluff or simply dismissed the American's words as tough talk and nothing more, unfortunately for the Japanese, the Americans did have the weapons they claimed they did, and weren't afraid to use them. Hiroshima was destroyed, though a catastrophe for the Japanese, it still did not mean their surrender. The Japanese, urged by their military establishment to continue the pursuit of victory still did not respond to the American threat. It took the Japanese another lost city in Nagasaki three days later to commence peace negotiations. It was too late for over 100,000 people by the time the treaty was signed aboard the American Battleship U.S. Missouri on September.2nd 1945. Japan had in essence, been defeated months before the bomb was dropped, the problem no longer existed to defeat Japan, but to secure her surrender- a far more difficult task. Quite simply, the Japanese did not believe in surrender. Their nation had never lost a war. In addition, Japan's fighting men held ingrained beliefs that to surrender was to disgrace one's self and one's nation. So deeply were these thoughts held that even after both bombs had been detonated and the entry of the Soviet Union into the war, the Japanese military still opposed surrender bitterly, and would prefer death than dishonorable capitulation. With a foe with a mind set such as this, only two options could be considered by the United States government. One being the use of atomic weapons and the other being the invasion of mainland Japan. According to Truman's top military advisors, an invasion of mainland Japan would cost

Art History - Essay Example The Ramones was a rock and roll band formed in Forest Hills, Queens New York that started in 1974. In their song ‘Do You Remember Rock n Roll on Radio’, Joey sings ‘It’s the end, the end of the seventies/it’s the end of the century.’ In this context, the end of the 20th century can be termed to have come early with regard to art form expression. This can was seen in the new and bold approaches that artists sought to express their ideas and themes in art. What was regarded as contemporary in the 20th century world of art; was being replaced by romanticism and idealism that was before seen or witnessed in the art world. Art forms from the finals of the 20th and the first of the 21st centuries can be perceived to have been seemingly different from that of the 70s and late 80s. Despite these differences, the new art forms and their new ways of expression, there are similarities because they share the same themes of death, beauty, consumerism, ident ity and memorial. Of special interest and focus for this paper is the Chinese experimental art towards the end of the 20th century and the beginning of the 21st century, which revolutionized the way that Chinese art got expressed both domestically and internationally. Towards the end of the 20th century, Chinese art was regarded as thoughtful and tightly focused on the exploration of certain themes including ruins, transience and demystification (Chilvers and Glaves-Smith 303).
