Abstract: A system for decelerating an aerodynamic body includes at least two pair of rotor members mounted on the exterior of the body. Members of each pair are mounted at diametrically opposite locations on the body. The rotor members are adapted to rotate about axes perpendicular to the flight line of the body and thereby produce a drag on the body. By rotating the members to produce cancelling lift forces, a greatly increased drag force is induced on the body while maintaining its static stability. A modification is also disclosed for powering the rotor members.
