Advanced Actuation Systems Development. Volume 2

This report describes six different research and development activities in flight control actuation. The activities are: (1) the development and test of a unique linear actuator sealing system for high pressure systems, (2) the development and test of a digital servovalve using piezo-controlled high speed solenoid valves, (3) the performance evaluation of an F-15 rudder actuator under applied loads, (4) the performance evaluation of a Mission Adaptive Wing section under different load conditions, (5) the evaluation of output impedance modification of an electrohydraulic actuator for flutter suppression, and (6) the development and test of a direct drive valve and electronics (analog and digital) for an F-16 Horizontal Tail/Flaperon actuator. Volume I of the report presents activities 1, 2, and 3. Volume II present activities 4, 5, and 6. See also Volume 1, AD-A213 334.
