The unique RSA is a vane type shock absorber. The fluid-filled opposing chambers are interconnected through a metering valve. Rotational force applied to the end of the wingshaft displaces the fluid from the high-pressure chamber to the opposing low-pressure chamber. This causes a resistance to relative motion and damping of the input force. The amount of damping torque is governed by angular velocity of the load applied to the shock absorber and by the valving settings.
