Abstract:
A system for controlling the aerodynamic drag of a motor vehicle includes a porous wall that closes externally a chamber obtained within a component of the structure of the motor vehicle in such a way that, when the motor vehicle is travelling, a first part of the pores situated in an area of the aerodynamic field of the vehicle with higher relative pressure enables part of the flow of air that laps the vehicle to enter the chamber. A part of the pores situated in an area of the aerodynamic field of the vehicle with lower relative pressure functions as an outlet for the flow of air from the chamber towards the outside of the vehicle in such a way as to generate jets of air that cause detachment of the boundary layer.
