Question:
At the exit of turn 11 as your car turn at 20 km/h, initially the DRS is deactivated. At the straight line, as the car reaches 80 km/h the DRS is activated and continuously throughout the whole sector 2. Assume your car will reach a maximum speed of 240 km/h at the end of sector 2.
Calculate in detail the coefficient of drag CD and the drag force, FD provided by the rear wing before and after the DRS is activated. Plot the results of CD and FD against the Reynold’s Number (20 km/h to 240 km/h).
JUST DO ASSUMPTION IF YOU SEE ANY DETAILS LEFT .
The guidelines/requirements are as follow:
a. The rear wing airfoil must be a single piece rectangular flat plate. The width, b must not exceed 100 cm. No restriction is given to the airfoil height, h. Ignore the airfoil holder or any other rear wing structure in your calculation. Assume the airfoil is weightless. WE ALREADY GIVE DIMENSION , b (length)= 0.8 m , h (width ) = 0.40m
b. The rear wing must be accompanied with a two stage (deactivated and activated) DRS functionality shown in Figure 3. The DRS can only and must be used at the exit of turn 11 sector 2 (the longest straight line of the circuit).
c. The drag force must be calculated using the following assumptions. During DRS deactivation, assume the inclination, ANGLE is 90 DEGREE to the horizontal. Provide all necessary assumptions for your calculation. During DRS activation assume leading edge.If the flow is laminar, assume approximate solution of parabolic profile and if the flow is turbulent assume the profile of PICTURE LAST . Also consider a mixed flow regime if it is present. Clearly state your references.
d. The maximum drag force on the airfoil must not exceed 2 kN to avoid failure and fatality.
