An actuator system for a control surface of an aircraft having a hydraulic system and a source of actuation system commands. The actuator system includes hydraulic circuits connected to the aircraft hydraulic system and an electrically-powered hydraulic circuit integrated with the actuator. The electrically-powered hydraulic circuit includes an electric motor connected to a hydraulic fluid pump. The pump can be controlled to adapt to the power requirements to actuate the control surface.
A hybrid control surface actuation system for a craft operating in a fluid, the craft having one or more fluid-dynamic control surfaces, a first hydraulic system adapted to produce and carry hydraulic pressure to each of the control surfaces, and a control surface actuation signal system adapted to produce a signal for controlling at least one of the control surfaces, comprising: one or more local hydraulic systems, each local hydraulic system being associated with a distinct one of the one or more fluid-dynamic control surfaces and including: first tran...
