This SAE Aerospace Information Report (AIR) includes all missile and launch vehicle actuation systems, including electrohydraulic, electropneumatic, and electromechanical types. The data for many systems are not complete. As more information becomes available, periodic updates will be issued to complete existing data sheets and to add new ones. An index by type of vehicle and by type of actuation system is included. The actual data sheets in the body of the report are organized in alphabetical order. A survey of existing designs (past and present) is a valuable aid during the concept formulation stage of a new design. This summary report on missile and launch vehicle actuation systems has been formulated to provide a data base that should be useful in the initial design stages of a new system.
