METHOD OF CONTROLLING TURBINE RADIAL CLEARANCES IN STARTING GAS-TURBINE ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: cooling stators of turbines up to a temperature that is no less than atmospheric temperature is implemented simultaneously with supplying heating fluid to a cooling system. This temperature is maintained from the beginning of rotation of the rotor, which is implemented by a starting apparatus, up to a moment when the engine is reached a low gas regime. EFFECT: enhanced accuracy of controlling. 1 dwg
