A motor vehicle with a device for controlling aerodynamic flow using synthetic jets

摘要

A motor vehicle has: at least one portion of external surface with one or more openings (1); and an internal cavity communicating with said opening or openings, and delimited at least in part by one or more mobile elements. Actuator means displace each mobile element between two operative positions so as to vary cyclically the volume of said internal cavity for the purpose of generating one or more jets of air (J), pulsed at a pre-set or controlled frequency (synthetic jets), which interact with the flow of air that laps the bodywork of the motor vehicle causing it to change its aerodynamic characteristics.
