ABSTRACT:
A passive step trimmer for a maneuvering re-entry body (MRB) which uses existing inertial forces acting on the MRB to deploy a free flowing mass from the rear of the MRB to trim the MRB altitude. The mass deployment from the MRB causes a forward shift in the center of gravity (CG) which in turn creates a more stable body which flies at a reduced angle-of-attack (.alpha.).
