DEVICE FOR MEASUREMENT OF TEMPERATURE IN FLOWING CHANNEL FOR PRIMARY FLOW OF DOUBLE-FLOW TURBOJET ENGINE Russian patent published in 2015 - IPC G01K1/14 G01K13/02 F01D17/08 F04D27/00 F04D29/00 

FIELD: instrumentation.

SUBSTANCE: invention relates to instrumentation and can be used for measurement of temperature in primary flow of a two-shaft double-flow turbojet engine. The invention provides the device for measurement of temperature at the compressor inlet in the flowing channel of primary flow of a double-flow turbojet engine. The device contains an air-tight hollow structure forming a connecting bracket (36b) of the intermediate casing (30) of a turbojet engine and implemented with a possibility for primary flow to pass radially through the flowing channel (16), and the flowing channel (18) for a turbojet engine secondary flow. The connecting bracket (36b) has at least one air inlet (44) opened to the primary flow flowing canal at the compressor inlet and at least one air outlet (46) implemented so that to direct into the turbojet engine zone where ambient pressure is less than the pressure in the primary flow flowing channel at the compressor inlet. The device includes a temperature sensor (48) the sensitive element of which is placed in the connecting bracket.

EFFECT: improvement of accuracy of obtained data.
