Formula One Cars – Grand Prix Cars a look at the F1 car operations and Dynamics in detail

Formula One Cars

Formula One Cars

Modern Formula One cars are mid-engined open cockpit. Hence open wheel single-seaters. As a result the chassis is made largely of carbon fibre composites. Rendering it light but extremely stiff and strong. Thus, the whole car, including engine, fluids and driver . Weighs only 605 kg. In fact this is the minimum weight set by the regulations. As a result, the cars are so light that they often have to be ballasted up. So to this minimum weight.

The cornering speed of Formula One cars . Is largely determined by the aerodynamic down force that they generate. Which pushes the car down onto the track. Of course, this is provided by ‘wings’ mounted at the front and rear of the vehicle. Also, by ground effect created by the movement of air. Under the flat bottom of the car.

A significant difference in the design. Hence, of the latest breeds of F1 cars . Is that they make far greater use of vortex “lift,” or in this case, down force. Since a vortex is a rotating fluid that creates a low pressure zone at its center. Creating vortices lowers the overall local pressure of the air.

Since low pressure is what is desired under the car. Thus, allowing normal atmospheric pressure to press the car down from the top. Creating vortices, down force can be augmented while still staying within the rules.

Formula One Cars to limit performance

The aerodynamic design of the cars is very heavily constrained to limit performance and the current generation of cars sport a large number of small winglets, “barge boards” and turning vanes designed to closely control the flow of the air over, under and around the car. The “barge boards” in particular are designed, shaped, configured, adjusted and positioned not to create down force directly, as with a conventional wing or under body venturi. They are designed so that air spillage from their edges will create these vortices.

The other major factor controlling the cornering speed of the cars is the design of the tyres. Tyres in Formula One are not ‘slicks’ (tyres with no tread pattern) as in most other circuit racing series. Each tyre has four large circumferential grooves on its surface designed to further limit the cornering speed of the cars.

 

Engines are mandated as 2.4 litre normally aspirated V8s, with many other constraints on their design and the materials that may be used. The previous generation of 3-litre V10 engines are also allowed, albeit with their revs limited and with an air restriction to limit performance.

Formula One Cars to use air restrictions

For 2007 the V8 engines will be restricted to 19,000 rpm with limited development areas allowed, following the engine specification freeze from the end of 2006. As outright speed and power are effectively being capped it is widely believed that teams will work on improving reliability, and the torque range of the engine to improve drive ability.

A Honda Formula One car, running with minimum down force on a runway in the Mojave desert achieved a top speed of 415 km/h (258 mph) in 2006. According to Honda, the car fully met the FIA Formula One regulations.

Even with the limitations on aerodynamics, at 160 km/h. Aerodynamically generated down force is equal to the weight of the car. Hence, the often repeated claim that Formula One cars are capable of ‘driving on the ceiling’ remains true in principle. Although it has never been put to the test. At full speed down force of 2.5 times the car’s weight can be achieved.

Formula One Cars can achieve a lateral force

The down force means that the cars can achieve a lateral force. Consequently, of around four and a half times the force of gravity (4.5 g) in cornering.Thus, a high-performance road car might achieve around 1 g. Consequently, in corners the driver’s head is pulled sideways with a force equivalent to 25 kilograms. Such high lateral forces are enough to make breathing difficult. So the drivers need supreme concentration to maintain their focus for the 1 to 2 hours .That it takes to cover 305 kilometers.
