DEVICE FOR METERING OF MEAN TEMPERATURE OF GAS-TURBINE ENGINE EXHAUST GASES Russian patent published in 1997 - IPC

FIELD: mechanical engineering; engine checking facilities. SUBSTANCE: device has measuring channel thermocouples installed over perimeter of preset section of gas-turbine engine and connected in parallel by compensating leads with conductance of two types. Thermocouples of two independent control channels are installed in placed where thermocouples of measuring channel are installed. Thermocouples in each control channel are connected in pairs by first compensating leads. Second compensating leads are connected to middle points of indicated leads. Output compensating leads of the types of conductance the same as those of the second leads are connected to middle points of the second leads in upper and lower portions of preset section of gas turbine engine. Like compensating leads of the same type of conductance are identical. Diameters of all compensating leads of the same type of conductance are equal. EFFECT: enlarged operating capabilities. 3 dwg
