Abstract
The object of this study is the optimization of a competition go kart aerodynamic in order to establish a new world speed record. To achieve this aim a standard chassis is modified to include a roll-cage to protect the pilot. To obtain the best aerodynamic penetration, the chassis is integrated with an external shell that replaces the side pods and the front nose of traditional go kart. The aerodynamic study was focalised on finding the best "cx" and the pressure loads, variable with speed, on the chassis. The system was first modelled in a parametric C.A.D. software and then transferred to a F.E.M. software to select a material that guarantees enough strength and stiffness margin for the structure loaded with the maximum pressure loads. To meet such requirements a carbon composite material monocoque solution was adopted.
