Abstract:
1. An emergency power system comprising: a plurality of solid propellant gas generators, each of said solid propellant gas generators having a gas outlet in fluid communication with a first conduit; said first conduit in fluid communication with a second conduit through a fixed or variable area flow restriction orifice; said first conduit in fluid communication with a third conduit; said third conduit in fluid communication with a flow control valve inlet of a flow control valve; said flow control valve having a first control valve position wherein said flow control valve inlet is in fluid communication with said second conduit through said flow control valve; said flow control valve further having a second control valve position wherein said flow control valve inlet is closed; said flow control valve further having a third control valve position wherein said flow control valve inlet is in fluid communication with an external environment; said second conduit in fluid communication with a turbine inlet of a gas turbine housing; each of said solid propellant gas generators being individually actuatable to provide a gaseous output capable of rotating a turbine wheel rotationally disposed within said gas turbine housing; and said turbine wheel being in rotational communication with an electric generator input shaft, a fluid pump input shaft, or with both said electric generator input shaft and said fluid pump input shaft, of said emergency power system.
