ABSTRACT:
Means for reducing the air drag on bluff vehicles are disclosed which facilitate improved fuel mileage and reduce induced air turbulence adjacent the vehicle. In one embodiment the air drag reducing means employs an airvane member secured in spaced relation to an air flow guide element in kit form for mounting adjacent a corner edge of the bluff surface to prevent separation of air flow from the corner edge and adjacent rearward surface of the vehicle and develop a net forward thrust on the air drag reducing means. Another embodiment includes an airvane member and means for mounting it adjacent a smooth curved windward corner edge of a bluff surface on the vehicle so as to define an air flow passage through which air passes from the bluff surface in attached relation to the corner edge and adjacent rearwardly extending surface of the vehicle.
