Abstract
A flight vehicle, such as a missile, operates both atmospherically and exo-atmospherically. The flight vehicle has control surfaces which are able to rotate relative to a fuselage of the flight vehicle, with the control surfaces extending outside of the fuselage into the airstream (or space) around the fuselage. The control surfaces may be used to control attitude in both atmospheric flight and exo-atmospheric flight. In atmospheric flight the control surfaces operate conventionally, with the aerodynamic forces on the control surfaces creating a torque on the flight vehicle. The control surfaces may be selectively positioned, such as by use of actuators, to achieve the desired torque on the flight vehicle, to achieve the desired attitude. In exo-atmospheric flight the control surfaces can be used as momentum wheels, with the control surfaces selectively rotated to produce a reaction torque on the fuselage.
