F1 and its Prohibited Technologies

Formula1 (F1) modern car capable of racing 100 kph from the rest about 1.7 seconds. One exceptional ability that any kind of sports car has not been able to match it.

F1

Apparently, not all the technology on the F1 car is the most sophisticated in the automotive world. Some systems and components of the F1 car just less advanced than ordinary cars on the streets. Why is that?

The answer is regulation. The Federation Internationale de l’Automobile (FIA) as the “umpire” for the F1 race diligently makes the regulation to limit the speed of the F1 car. In addition to the safety of racer, speed limits are also related to non-technical reasons. Examples of making the race more interesting to watch.

Given the history, FIA regulatory changes are done almost every year. The move was implemented because the technological progress was far more rapid than the restrictions imposed. Here are some innovative technologies ever used by the F1 car but then “forbidden”.

turbine Gas Technology F1

The gas turbine is used as a drive to replace Torak fuel motor. As one of the oldest types of movers, combustion engines have many disadvantages. Especially compared to gas turbines are more recently found. Gas turbines produce higher power with lighter weight. It can be said that gas turbines have the better power-to-weight ratio.

Another plus is the very fast rotation, up to 60,000 rpm. Compare with the modern F1 engine that is “only” capable of turning around 20,000 rpm (and this season is limited by the FIA to a maximum of 15,000 rpm only). Gas turbine classified as minimal vibration because there is no component that moves translation (back and forth) as well as motor fuel.

Generally, the age of gas turbine is longer than motor fuel. The FIA banned the use of this turbine after Team Lotus piloted the T56B which adopted the Pratt & Whitney gas turbine in 1971.

This FIA ban is actually “redundant” because Team Lotus proves that the use of gas turbines as the driving force of this car is actually not suitable for F1. Weaknesses that are felt by others is the gas turbine slow response to changes in gas openings from the foot of racer. As a result difficult to eat chicane and the absence of engine-brake effect is needed F1 car.

CVT

Continuously Variable Transmission (CVT) is a gearbox replacement device that allows the engine to operate on a narrow band-RPM. The effect of maximum torque can be maintained. Williams is the team that first tried to develop this technology since the late 1970s.

It was even tested on a Renault-powered FW-15 in 1993. But the move was finally limited to testing because in late 1993 the FIA banned its use for the race.

Fan

The use of the fan (fan) behind the car to generate extra-downforce is also prohibited FIA. This tool was used by the Brabham team and Niki Lauda made him win the Swedish Grand Prix in 1978.

Side skirts

Side skirts or sliding skirts are shaped-like devices – skirts and mounted on the left and right sides of the lower car body. This tool is used to prevent wind flow under the car flowing to the side so that the ground-effect of under the car can be maximized.

In 1980 the FIA banned the side skirts by limiting ground clearance to a minimum of 6 cm. As a result side skirts cannot be used again because the distance between the component with the asphalt cannot be maintained. Moreover, the suspension movement that causes the car body to move up and down.

Nevertheless, F1 engineers did not stop improvising. In 1988, the T88 car from Team Lotus introduced a twin-chassis or dual chassis design. The first chassis has a very hard suspension on the wheels. While the second chassis has a softer suspension of the first chassis.

The first chassis has a very hard suspension of the wheel, so its distance to the asphalt can be maintained. Start strategy by making the first chassis similar to the plate that surrounds the second chassis, then the first chassis can serve as “side skirts” without breaking the minimum 6-cm ground-clearance rule. However, this twin-chassis was finally banned FIA.

Shock absorbers

The active suspension is a “magical device” that helped Williams dominate the 1992 racing season with Nigel Mansell and his FW14B. The active suspension makes the shock absorber capable of adjusting the dampness to suit the road conditions. In effect, all four tires will always have maximum traction despite being on a bumpy track and many slow turns. This device was banned by the FIA in the 1993 season.

The ‘eighty four and ‘eighty five GSL-SEs are king, with their gasoline-injected 13B engines, restricted-slip differentials, and higher brakes.\n\nIni adalah cara untuk menjadi tetangga yang lebih baik. When I say broker, I really imply anyone with a used car vendor license who is willing to purchase for another person at a wholesale seller public sale. If we started happening and on concerning the CRX’s legendary gasoline financial system (forty three/forty seven MPG), you’d know we have been filled with it. The CRX makes our list as a result of it turns like a go-kart on Velcro.\n\nHe as soon as claimed to avoid wasting by solely getting his hair reduce when he is in developing countries. All these factors together forge a system the place automobiles are bought at very low prices and ultimately piles up the number of almost new or barely used automobiles. In a world of retro automobiles appreciating sooner than we will actually get the cash collectively to purchase them, motors like the common-or-garden third-gen Prelude are wanting fairly damn tempting.\n\nEnter your e-mail deal with to obtain alerts when now we have new listings out there for Cheap vehicles for sale Coventry. Because businesses and the self-employed who drive rather a lot are perfectly tremendous with buying a workhorse, while people always desire a showhorse and do not perceive that a number of dings and dents include that discount worth.…
