# Usin foilsim software and plotting a graph

Anonymous

Question description

Calculate the maximum speed of the car around the four bend radii without the aerofoils, for each of the four tyre conditions.

 Before attempting the next questions, please watch the set of tutorial videos, by following the links given in the appendix.

 Use Foilsim (undergraduate edition) to design two aerofoils which fit the car (they must use the span and chord values determined by you – see below).

 To determine the chord and span of each aerofoil, perform a Google image search to find a top view of an F1 car, and using the maximum width (approx. 1.8 m) as a scaling reference, measure the dimensions for your car. Then copy the image into a programme such as MS Paint and measure it to obtain the positions of the wheels, wings and overall length. You will use these measurements as the basis of your calculations.

2. Calculate the new maximum speed for each bend radius, for each of the four tyre conditions.

3. Plot a set of graphs which concisely summarise all your findings (with / without aerofoils, bend radius, tyre friction coefficient).

4. When the car is without aerofoils, calculate the forces for one particular corner radius / tyre combination and determine whether the front or the back tyres slip first
