Aerodynamic system for e.g. car, has electro-mechanical unit arranged near swirl zones for transforming electricity into vibrating waves to re-join air flow in swirl zones and including piezoelectric membrane overmolded in body part
Aerodynamic system for e.g. car, has electro-mechanical unit arranged near swirl zones for transforming electricity into vibrating waves to re-join air flow in swirl zones and including piezoelectric membrane overmolded in body part
The system has an electro-mechanical unit (26) arranged near swirl rolling zones (40, 42) for transforming electricity into vibrating waves in order to re-join air flow in the swirl zones. The electro-mechanical unit creates the waves by vibration of a rear upper body part (14) of a motor vehicle e.g. car, and includes electro active polymers and a piezoelectric membrane e.g. piezoelectric film in plastic material, that is overmolded in the body part. An independent claim is also included for an assembly of a body part of a motor vehicle and an aerodynamic system.
