Motor vehicle body aerodynamic force reduction system comprises air ducts with inlets and outlets that reduce drag and lift

摘要

The system consists of a series of air ducts in zones of air turbulence on the vehicle body, the ducts extending parallel to the vehicle's lengthwise axis. Each duct has an inlet (11) and outlet (12), with the inlet equipped with a regulator in the form of a hinged flap controlled by pressure and/or speed and/or friction sensors implanted in the vehicle's bodywork, or by a computer monitoring the vehicle's different operating parameters. It also has sharp edges and tapers in width from its inlet to its outlet end.
