Aero-engine afterburner heat shield wall surface temperature measuring method

The invention belongs to the technical field of aero-engine afterburner heat shield wall surface temperature measurement, and particularly relates to an aero-engine afterburner heat shield wall surface temperature measurement method, which comprises the steps of removing dirt on a heat shield wall surface; placing a thermocouple in a to-be-measured temperature area on the wall surface of the heat shield; high-temperature glue is coated on the portion, needing to be fixed, of the thermocouple on the heat screen, the thickness of the high-temperature glue is 1/2 of the diameter of the thermocouple, and normal-temperature curing is carried out; the high-temperature glue cured at normal temperature is covered with silicon fiber cloth, and the silicon fiber cloth covers the part, needing to be fixed, of the thermocouple; coating high-temperature glue on the silicon fiber cloth, covering the silicon fiber cloth and the part, needing to be fixed, of the thermocouple, and carrying out high-temperature curing; the the
