The kinematics of the rigid feedback linkage, the impedance of the hydraulic servomechanism and the flutter occurrence

摘要

The paper brought to light a previous result of the author, used in the design of hydraulicservos actuating flight controls of the airplanes IAR 93 and IAR 99. The results highlights theimportance of the the kinematics of the rigid feedback linkage of the hydraulic servo in anaeroservoelastic frame.
