Abstract

The present invention relates to the improvement of the aerodynamic properties of bluff-body shaped ground vehicles. A least one air modulator is assembled on the vehicle to modify an air flow around the vehicle, such that the drag on the vehicle is decreased. Each air modulator has an array of openings including a number of openings, which are arranged next to one another along an essentially straight line. A control unit controls the at least one air modulator output oscillating air from each opening such that air vortices are formed outside the opening. The at least one air modulator is arranged on the vehicle, such that these air vortices have axes that, in proximity to the opening, are essentially perpendicular to a forward driving direction of the vehicle.
