The invention discloses a high-Mach-number test aircraft surface temperature measuring device and method, and belongs to the technical field of high-Mach-number test aircraft surface temperature measurement. The high Mach number test aircraft surface temperature measuring device comprises a thermocouple assembly and a data acquisition device. The thermocouple assembly comprises an anode thermocouple wire and a cathode thermocouple wire. The first end of the positive thermocouple wire and the first end of the negative thermocouple wire are twisted, and the end points, close to the positive thermocouple wire and the negative thermocouple wire, of the twisted section are set as welding parts which are fixed on the surface of an aircraft through spot welding; the second end of the positive thermocouple wire and the second end of the negative thermocouple wire are respectively connected with the data acquisition device, and temperature detection signals are transmitted back. The measurement device and method provided by the invention can improve the measurement reliability and response time efficiency of the surface temperature of the test aircraft.
