An SST flight control system has been analyzed and tested as a technical follow-on to the cancelled U.S.A. supersonic transport program. The quadruple-redundant horizontal stabilizer actuation system was evaluated to determine static performance, dynamic stability, force synchronization, dynamic flutter stiffness, electronically compensated stiffness, static stiffness, bottoming loads, failure detection and effects, and high hydraulic flow rate effects. Conclusions are that the actuation system concept was feasible and that linear analysis methods accurately predict the linear characteristics of the system.
