Stall recovery system for a ram air turbine
Abstract:
In one aspect, a ram air turbine stall recovery system includes a ram air turbine, a hydraulic pump powered by the ram air turbine with the hydraulic pump having a pump inlet and a pump outlet, an electric generator powered by the ram air turbine, a bypass line that connects the pump outlet to the pump inlet, a bypass valve located on the bypass line between the pump outlet and the pump inlet; and a controller responsive to an input signal that indicates a potential stall condition of the ram air turbine. The controller causes the bypass valve to open to allow a hydraulic fluid to flow through the bypass line in order to reduce a pressure within the hydraulic pump.
