DEVICE FOR ADJUSTING ROTATABLE GUIDES OF BLADES OF COMPRESSOR OR TURBINE OF GAS TURBINE ENGINE

摘要

FIELD: gas turbine engineering. SUBSTANCE: pickup 1 is mounted on housing 24 of an engine. When the engine operates in intermediate conditions pickup 1 measures deflection of angular position of the blades and a signal from the pickup is fed to the control electronic unit. The unit produces a signal proportional to the correction of the rotation speed of the engine . This signal enters the drive mechanism that moves the rotatable ring and guide blades. EFFECT: improved accuracy of the adjustment. 3 dwg
