GAS-TURBINE ENGINE FUEL FEED SYSTEM

摘要

FIELD: aircraft industry; engines. ^ SUBSTANCE: invention can be used in electronic hydromechanical systems of automatic control of gas-turbine engines. According to invention, to improve reliability of gas-turbine engine in operation and reduce cost of maintenance, high-pressure electric pump is made in form of plunger pump with electric drive and two-position wobble plate connected with electrohydraulic mechanism whose input is connected with output of electronic governor. Reliability of gas-turbine engine in operation and reduction of maintenance costs are provided by adjusting capacity of pump in process of operation of gas-turbine engine during its service life and owing to possibility of adaptation of proposed system for modifications of basic gas-turbine engine and other gas-turbine engines of said class without changing design of system. ^ EFFECT: improved reliability of engine. ^ 1 dwg
