Abstract
A hydraulic power supply system utilizing a turbine-driven pump in a hydraulic circuit and a solid propellant gas generator providing gas for driving the turbine. A gas pressure relief valve is operable to maintain the gas generator at constant pressure and has a range of pressure settings to vary the burn rate of gas generator and, thus, the power delivered to the turbine dependent upon the flow demands on the pump. There is a relatively low pressure setting when there is a reduced flow demand on the pump. The control provided by the settable hot gas relief valve reduces the size and weight of a number of components of the hydraulic supply system.
