Aerodynamics Features of the F1 Vehicle.....[2]


Over time, as the wheels were moved closer to the chassis, the front wings overlapped the front wheels when viewed from the front. This created unnecessary turbulence in front of the wheels, further reducing aerodynamic efficiency and thus contributing to unwanted drag. To overcome this problem, the top teams made the inside edges of the front wing endplates curved to direct the air towards the chassis and around the wheels. Many teams later introduced sculpted outside edges to the endplates to direct the air around the front wheels. This was often included in the design change some teams introduced to reduce the width of the front wing to give the wheels the same position relative to the wing in previous years. The interaction between the front wheels and the front wing makes it very difficult to come up with the best solution, and consequently almost all of the different teams have come up with different designs


The relationship between the front wing and the track is a delicate one; with the wing generally being more efficient the closer it is to the track. Therefore, the front
wing is low to the ground to obtain as much advantage from ground effect as possible, and generally has one full spanning flap. Developments usually concentrate on the profile of the wing, and the use of flaps. However, Ferrari recently angled the leading edge of the wing to form a forward racing V-shape. This comes from flow
visualizations on the wing, which shows its suction power is so strong that it pulls air in from angles not straight with the centerline. This means that the air is approaching a normal, straight leading edge at an angle to it, and therefore not working the wing to its full potential. By turning the edge by the correct angle, maximum efficiency will be obtained.The part of the front wing, which tends to change most in design, is the endplate. The primary function of this feature is to stop
the high-pressure air on the top of the wing from being encouraged to roll over the end of the wing to the low-pressure air beneath, causing induced drag. Additionally, the design aim of the endplates is to discourage the dirty air created by the front tire from getting under the floor of the car. Further to these, some teams use 'splitters', which are vertical fences, attached to the undersurface of the front wing, to assist the endplate


Wheels

The wheels of a formula one car probably induce the most drag of any part of the car.Unfortunately, have yet to be redesigned to reduce aerodynamic drag.Hindering this innovation are certain technical regulations.One such regulation is that the wheels cannot be covered.F1 wheels must to be the shape they are and this causes separation behind them.This separation causes large amounts of form drag.The amount of generated skin friction drag is minimal in comparison.So far, it appears that not much can be done to reduce form drag on the wheels, however teams have used the front wing to try to deflect the oncoming air around the front tires.
