Aerodynamic Design of High Performance Cars: Discussion and Examples on the Use of Optimization Procedures

In the initial phase of the aerodynamic car project, difficulties arise from the large number of parameters involved. A systematic aerodynamic analysis taking into account the effects of all these parameters appears to be difficult. The use of a direct numerical optimization technique appears very attractive to solve this complex survey. In this paper a critical analysis of the most significant optimization methodologies is presented. The characteristics and the use of a specific optimization tool are also described, to highlight the capabilities offered by the optimization approach. The use of this procedure to increase the car safety, increasing the vertical down-load without affecting car performance, is detailed. Furthermore, the problems arising from the present implementation and the relevant indications for a more efficient and effective optimization procedure are discussed.
