Temperature test receptor part

Abstract

The invention discloses a temperature test receptor part. The temperature test receptor part comprises a supporting rod module, wherein a cool air chamber, an exhaust chamber and a wiring chamber arearranged in the supporting rod module, cool air holes, measure point holes, exhaust membrane holes, hot gas discharge holes and a tail edge exhaust hole are formed in an outer wall of the supporting rod module, and the measure point holes communicate with the wiring chamber through measure point hole chambers; the cool air holes, the exhaust membrane holes and the tail gas exhaust hole communicatewith the cool air chamber; the hot gas discharge holes communicate with the measure point hole chambers via the exhaust chamber; a sealing-in joint connected with the supporting rod module, wherein acompensation wire chamber is arranged in the sealing-in joint, and the compensation wire chamber communicates with the wiring chamber; thermocouple wire modules arranged in the wiring chamber and themeasure point hole chambers, wherein the thermocouple wire module is provided with a hot-joining point, the hot-joining point is arranged in the measurement point hole chamber and close to the measurement point hole; and a compensation wire arranged in the compensation wire chamber and connected with the thermocouple wire module. The temperature test receptor part disclosed by the application realizes the cooling to the supporting rod through a cooling structure, thereby satisfying a high-temperature test environment demand of a high-pressure turbine.

Description

Technical field [0001] The invention relates to the technical field of a high-pressure turbine full-temperature and full-pressure test, in particular to a temperature test sensing part. Background technique [0002] The high-pressure turbine full-temperature and full-pressure test conducts experimental research on the performance of the high-pressure turbine by simulating the actual working environment of the high-pressure turbine in the aeroengine. In order to obtain the total airflow temperature of the high-pressure turbine flow field, it is necessary to arrange a test sensing part at the outlet of the high-pressure turbine to measure the flow field temperature. The test section has the characteristics of high temperature (maximum temperature up to 1600K), high pressure (maximum pressure up to 1MPa) and high aerodynamic load (air flow Mach number up to 0.6). Therefore, higher requirements are put forward for the structural design of the test sensing part. The air flow tempera...

AI Technical Summary

Problems solved by technology

[0006] 1. The conventional sensing part is limited by the material, and does not have the ability to work in the high-temperature environment of the high-pressure turbine outlet, and cannot meet the requirements of the full-temperature and full-pressure turbine test

[0007] 2. The existing cooling technology of the sensing part requires a large modification of the high-pressure turbine test piece, which not only destroys its structural integrity but also easily causes performance attenuation

At the same time, it is necessary to provide a special cooling system for the test bench, and the cost is relatively high
