Abstract:
A combined lift and hydraulic fluid supply system for a gas turbine comprising:a first pump for receiving hydraulic fluid from a lubricating fluid system and selectively supplying hydraulic fluid at a first pressure, said first pressure being a pressure sufficiently high for lift system requirements for a gas turbine;a first valve operatively coupled for selectively supplying hydraulic fluid at said first pressure to a lift system of a gas turbine;a first fluid flow line for conducting hydraulic fluid from said first pump to said first valve;a second flow line in flow communication with said first flow line for receiving at least portion of the hydraulic fluid pumped by said pump, said second flow line being operatively coupled for supplying hydraulic fluid to a hydraulic system of the gas turbine; anda first pressure regulating valve in said second flow line for reducing a pressure of the fluid flowing therethrough from said first pressure to a lower, second pressure for gas turbine hydraulic system requirements.
