Control Systems for Reusable Launch Vehicles

Flight control requirements of reusable launch vehicles are reviewed and compared to those of aircraft, current launch vehicles, and spacecraft. Areas are identified in which more work on the flight control system will improve mission performance. Current work in three areas is briefly reviewed - the use of man in the control loop, the development of systems which can accommodate large changes in the flight conditions, and use of the flight control system to reduce wind-induced loading.
