Static pressure measuring structure for wall surface of thin-wall flow channel of gas compressor in aero-engine

The invention belongs to the technical field of gas compressor thin-wall flow channel wall surface static pressure measurement in an aero-engine, and particularly relates to a gas compressor thin-wall flow channel wall surface static pressure measurement structure in an aero-engine, and the structure comprises a static pressure hole which is formed in a flow channel wall surface; the circular groove is formed in the wall surface of the flow channel and is communicated with the static pressure hole; one end of the air pipe extends into the static pressure hole through the circular groove; the positioning ring is made of the same material as the air pipe, is arranged on the air pipe in a sleeving manner, is connected with the air pipe in a welding manner and is clamped in the circular groove; and the sealing ring is made of the same material as the wall surface of the flow channel, is arranged on the air pipe in a sleeving manner, is connected with the wall surface of the flow channel in a welding manner and is
