Abstract

A roll control system for a reentry vehicle having the pay load positioned within the vehicle so as to offset the center of gravity from the aerodynamic axis of the vehicle. A radial mass unbalance is created in the aft end of the vehicle to create a trim angle of attack dependent upon the vehicle roll rate which provides a source of roll torque with the out-of-plane radial center of mass offset. With the use of a mass and spring arrangement, the mass unbalance is controlled by centrifugal force to terminate the roll torque at the prescribed design roll rate.
