ABSTRACT:
An airfoil, pivotally attached to a high speed vehicle, is positioned to produce a braking action on the vehicle by means of fluid-dynamic resistance. The airfoil may be positioned to produce a downward pressure on the vehicle and thus enhance conventional braking action. The braking action is further augmented by eductors which reduce the air pressure behind the airfoil and control the air flow about the airfoil. The eductors and a set of rudders combine to provide the requisite stability for successful high speed braking.
