(Part3.),,Colin Chapman,,(Father of the ground effect)


Chapman, working with Tony Rudd and Peter Wright, pioneered the first Formula One use of "ground effect", where a partial vacuum was created under the car by use of venturis, generating suction (downforce) which held it securely to the road whilst cornering. Modern Formula One cars generate enough downforce (now generated by wings instead of ground effects) that they could theoretically be driven on a ceiling once they reach about 100 mph. Initially this technique utilized sliding "skirts" which made contact with the ground to keep the area of low pressure isolated. Chapman's next development was a car that generated all of its downforce through ground effects, eliminating wings and the drag that they introduce at high speed. However, skirts were eventually banned, because the skirt could be damaged, for example, from driving over a curb, and downforce would be lost and the car could then become unstable.

F1 1980: Williams tests a no-suspension F1 car to improve its ground effect


Paul Ricard, Dec. 1980. Williams and Alan Jones tried out a car without suspensions to seek max ground effect under the new no-skirt rule. Taken from 1981 BBC Horizon show "Gentlemen, Lift Your Skirts."

Formula 1 1978 - The Shape Of The Things To Come - Part 1


Review of the 1978 Formula 1 World Championship. In 1978 Colin Chapman made a Formula 1 car that would change Formula 1 forever. He created the Lotus 79. The car was build on the ground effect foundations that were laid by the Lotus 78. But the Lotus 79 proved to be the ultimate ground effect car in 1978. Mario Andretti became World Champion in the Lotus 79. Enjoy!!!

BBC - Horizon - aired on TV 1981 Williams Formula One team Winter testing with Alan Jones driving in December 1980 at the Paul Ricard circuit in Southern France. The day before testing started Goodyear Tyres had decided to quit F1 due to the ban announced by the FIA on "skirts". The FIA being based in France were subjected to increasing pressure from the Goliath corporate car manufacturers Ferrari (Fiat) and Renualt to ban skirts as their engines were the wrong shape to fully capitalise the use of ground effect in the design of their cars. This was the year before the Turbo revolution hit F1 and there is a brief look at the development of Turbo. Also features an in depth look at the Ford Cosworth engine and you are taken around the factory, design, hand building, performance and development of the engine. Includes appearences from the following. Frank Dernie (Head of Williams Research and Development) who currently works for the Toyota Formula One team. Frank explains the fundementals of ground effect and the importance of using skirts to achieve full potential. Patrick Head and Frank Williams. This is incredible footage documenting not just the Williams team but of the Cosworth engine

Car Aerodynamics


Aerodynamics The principles which allow aircraft to fly are also applicable in car racing. The only difference being the wing or airfoil shape is mounted upside down producing downforce instead of lift. The Bernoulli Effect means that: if a fluid (gas or liquid) flows around an object at different speeds, the slower moving fluid will exert more pressure than the faster moving fluid on the object. The object will then be forced toward the faster moving fluid. The wing of an airplane is shaped so that the air moving over the top of the wing moves faster than the air beneath it. Since the air pressure under the wing is greater than that above the wing, lift is produced. The shape of the Indy car exhibits the same principle. The shape of the chasis is similar to an upside down airfoil. The air moving under the car moves faster than that above it, creating downforce or negative lift on the car. Airfoils or wings are also used in the front and rear of the car in an effort to generate more downforce. Downforce is necessary in maintaining high speeds through the corners and forces the car to the track. Light planes can take off at slower speeds than a ground effects race car can generate on the track. An Indy ground effect race car can reach speeds in excess of 230 mph using downforce. In addition the shape of the underbody (an inverted wing) creates an area of low pressure between the bottom of the car and the racing surface. This sucks the car to road which results in higher <b>...</b>

Lamborghini Murcielago with aftermarket exhausts reving very hard and making wheelslide while accelerating fast.This Murcielago has chipped engine and the top speed is about 350 kmh. Review: The Lamborghini Murciélago is a two-door, two-seat sports car produced by Italian automaker Lamborghini between 2001 and 2010. Successor to the Diablo and flagship of the automaker's lineup, the Murciélago was introduced as a coupé in 2001. The automaker's first new design in eleven years, the car was also the brand's first new model under the ownership of German parent company Audi. It was styled by Peruvian-born Belgian Luc Donckerwolke, Lamborghini's head of design from 1998 to 2005. A roadster version was introduced in 2004, followed by the updated LP 640 coupé and roadster and limited edition LP 650-4 Roadster. The final variation to wear the Murciélago nameplate was the LP 670-4 SuperVeloce, powered by the largest and final evolution of the historic Lamborghini V12 engine. Production of the Murciélago ended on November 5, 2010, with a total run of 4099 cars.

Ronnie Peterson - 30 Years After Tribute


My tribute to Ronnie Peterson the "Super Swede" who died during the 1978 Italian Grand Prix at Monza in an horrible start crash. He was one of the most talented and best skilled drivers during the 70's. After driving carts and participating at Formula 2 he entered Grand Prix Racing in 1970. He was driving for March, Lotus( Lotus 72 & 79 ground car effect) and Tyrrell ( six - wheeler) always with a Ford Cosworth V8 engine. For the 1979 season he already signed a contract with Mclaren. Some of his team mates were Niki Lauda, Emerson Fittipaldi, Jacky Ickx, Vittorio Brambilla, Hans Joachim Stuck and Mario Andretti the 1978 worldchampion. He won 10 of his 123 races, conquered the Pole Position for 14 times and made 9 fastest laps. He was the most successful Swedish racing driver at F1. After all these years he still isn't forgotten.

Inside a Formula 1 Car -- Aerodynamics


In Formula 1 races, aerodynamics are one of the most important elements to achieving great speeds. Formula 1 vehicles have smaller frontal areas to maximize the amount of power used to propel it, and decrease the amount of wind resistance encountered. The Panasonic Toyota Racing Team spends an estimated 8000-9000 hours a year developing the vehicle in specially-designed wind tunnels, as well as working on CFD, computational fluid dynamics -- a computer program used to unearth air flow patterns over the car.
