TURBINE COOLING SYSTEM OF GAS-TURBINE ENGINE Russian patent published in 2005 - IPC

FIELD: mechanical engineering; gas-turbine engines.

SUBSTANCE: proposed turbine cooling system of gas-turbine engine contains interconnected by air ducts place to take-off compressed air from compressor, supercharger, check valve - signaling device, emergency release valve, turbine cooled parts temperature transmitter, heat exchanger and turbine cooled parts channels. Check valve-signaling device is connected by its input with place of compressed air take-off from compressor, and by output, with supercharger. Emergency release valve is connected by input with output of channels of turbine cooled parts, and by output, with engine passage part. Turbine cooled parts temperature transmitter is connected at output with emergency release valve. Supercharger is furnished with capacity control unit connected with output of turbine cooled parts temperature transmitter. Heat exchanger is installed between supercharger and turbine parts cooled channels. Output of turbine parts cooled channels is connected with input of supercharge.

EFFECT: improved efficiency of gas-turbine engine cooling system owing to possibility of control of cooling of turbine parts depending on their temperature conditions.
