AIRCRAFT GAS TURBINE ENGINE STARTING METHOD

摘要

aircraft industry. SUBSTANCE: in process of engine starting, rotation from shaft of turbostarter is transmitted through overrunning clutch to shaft of engine to be started and simultaneously to shaft of positive-displacement hydraulic pump. Working liquid from pump output is passed through sets of aircraft control systems. For this purpose corresponding cocks are to be opened. It decreases consumption of power by positive-displacement hydraulic pump owing to reduction of pressure behind the pump caused by increase of effective area at output. EFFECT: provision of reliable starting of aircraft engine with connected positive-displacement hydraulic pumps communicating with aircraft control system without disconnection of pumps and without increase of power required by turbostarter. 2 cl, 2 dwg
