Abstract

An analysis is carried out to reveal an influence of hydraulic actuator operation mode on a motion stability of aircraft control surfaces. Some recommendations are suggested to choose a damping value for these control surfaces in case of activated or deactivated hydraulic system as well as design solutions ensuring needed damping level for these control surfaces.
