Wiring method for high-temperature strain gauges of blades of middle-stage blisk of gas compressor

The invention provides a wiring method for high-temperature strain gauges of blades of an intermediate-stage blisk of a gas compressor, and belongs to the technical field of high-temperature dynamic stress testing of gas compressors of aero-engines. Through holes are formed in the centers of the front-stage blisk and the middle-stage blisk, an armored wire penetrates through the through hole of the front-stage blisk, a pin wire of the strain gauge extends to the position of the through hole of the middle-stage blisk to be tested, and the pin wire of the strain gauge is reserved; the tested middle-stage blisk is installed on the installation edge of the front-stage blisk, in the installation process, the armored wire on the front-stage blisk penetrates through the through hole in the tested middle-stage blisk, and switching of the armored wire and the pin wire is carried out on the rear side plane of the tested middle-stage blisk. According to the invention, the reliability of the dynamic stress test of the bl
