GAS TURBINE ENGINE CONTROL SYSTEM Russian patent published in 2002 - IPC

FIELD: mechanical engineering; turbines. SUBSTANCE: in proposed control systems of gas turbine engine cutoff and stop valves are provided with electromagnetic drives, system is provided also with unit automatic control system and valve control unit one power inlet of which is connected with ac power voltage bus, and other power inlet is connected with DC power voltage bus. Control inlet are connected with unit automatic control system and outlets are connected with windings of electromagnetic drives of cutoff and stop valves with possibility of taking off short-time power voltage and then operating voltage and outlets are connected with windings of protective electromagnet of control valve and electromagnetic starting and standby valves for taking off operating voltage. Outlet is connected with windings of electromagnetic drives of pulse valves of outlet air valves with possibility of taking off either power or operating voltage. EFFECT: improved reliability and quick action of control systems of gas turbine engines in case of operation of protection by using cutoff and stop valves with electromagnetic drives and valve control unit. 2 cl, 1 dwg
