You are required to advise on using a wind tunnel for testing a
scale model of a car for aerodynamic performance. i. You have been
given that the maximum velocity of the car is 140 km/h and the wind
tunnel can handle air velocities up to 300 km/h. The car design
team has a 1/4 scale model of the car for testing. Determine
whether the 1/4 model can be used for wind tunnel testing. ii. The
wind tunnel has a test section that is twice as wide as the car
model. Comment on the appropriateness of this wind tunnel for
testing. iii. Using an appropriate sketch explain where the centre
of gravity of a vehicle should lie in comparison to the centre of
pressure (consider side winds)
