Formula 1 - Grand Prix Automobiles

By Michell Akins


Contemporary Formula One vehicles are mid-engined open cockpit, open wheel single-seaters. The chassis is created largely of carbon fibre composites, rendering it light but incredibly stiff and robust. The whole auto, such as engine, fluids and driver weighs only 605 kg. The truth is this really is the minimum weight set by the regulations - the cars are so light that they often have to be ballasted up to this minimum weight.

The cornering speed of Formula A single vehicles is largely determined by the aerodynamic downforce that they create, which pushes the automobile down onto the track. This really is provided by 'wings' mounted in the front and rear of the vehicle, and by ground impact produced by the movement of air beneath the flat bottom from the vehicle.

A significant difference inside the design on the newest breeds of F1 automobiles is that they make far higher use of vortex "lift," or within this case, downforce. Given that a vortex is really a rotating fluid that creates a low pressure zone at its center, generating vortices lowers the general neighborhood pressure of the air.

Since low pressure is what exactly is preferred under the auto, permitting regular atmospheric pressure to press the auto down from the prime, by making vortices, downforce could be augmented while still staying inside the guidelines.

The aerodynamic style in the cars is very heavily constrained to limit overall performance and the present generation of vehicles sport a big variety of small winglets, "barge boards" and turning vanes developed to closely control the flow from the air more than, beneath and about the auto. The "barge boards" in certain are developed, shaped, configured, adjusted and positioned not to create downforce directly, as using a traditional wing or underbody venturi. They may be developed so that air spillage from their edges will generate these vortices.

The other significant issue controlling the cornering speed from the automobiles is the style from the tyres. Tyres in Formula One will not be 'slicks' (tyres with no tread pattern) as in most other circuit racing series. Every single tyre has four huge circumferential grooves on its surface designed to additional limit the cornering speed in the vehicles. Suspension is double wishbone or multilink all round with pushrod operated springs and dampers on the chassis. Carbon-Carbon disc brakes are employed for decreased weight and increased frictional overall performance. These give an extremely high level of braking efficiency and are usually the element which provokes the greatest reaction from drivers new for the formula.

Engines are mandated as two.4 litre typically aspirated V8s, with many other constraints on their style and the materials that could be utilized. The 2006 generation of engines rev close to 20,000 rpm and create as much as 740 bhp (552 kW).[10] The previous generation of 3-litre V10 engines are also allowed, albeit with their revs limited and with an air restrictor to limit functionality.

Engines run on unleaded fuel closely resembling publicly accessible petrol. The oil which lubricates and protects the engine from overheating is quite equivalent in viscosity to water. For 2007 the V8 engines is going to be restricted to 19,000 rpm with restricted development locations allowed, following the engine specification freeze in the end of 2006. As outright speed and energy are effectively being capped it's extensively believed that teams will work on improving reliability, along with the torque array of the engine to enhance driveability.

A wide variety of technologies - like active suspension, ground impact aerodynamics and turbochargers - are banned beneath the current regulations. Despite this the 2006 generation of vehicles can attain speeds of as much as 350 km/h (about 220 mph) at some circuits (Monza).A Honda Formula 1 car, running with minimum downforce on a runway in the Mojave desert achieved a top speed of 415 km/h (258 mph) in 2006. Based on Honda, the automobile totally met the FIA Formula One regulations.

Even with all the limitations on aerodynamics, at 160 km/h, aerodynamically generated downforce is equal towards the weight of the auto along with the usually repeated claim that Formula One cars are capable of 'driving around the ceiling' remains true in principle, despite the fact that it has in no way been place for the test. At full speed downforce of 2.5 times the car's weight might be accomplished.

The downforce implies that the cars can obtain a lateral force of about four plus a half times the force of gravity (four.5 g) in cornering - a high-performance road automobile may possibly achieve about 1 g. Consequently in corners the driver's head is pulled sideways with a force equivalent to 25 kilograms. Such high lateral forces are adequate to produce breathing tough along with the drivers require supreme concentration to preserve their concentrate for the 1 to 2 hours that it takes to cover 305 kilometres.
