The invention belongs to the technical field of aircraft afterbody dynamic pneumatic and thermal load measurement, and particularly relates to an aircraft afterbody dynamic pneumatic and thermal load measurement method, which is characterized in that a pressure sensor is mounted at an aircraft afterbody dynamic pneumatic load measurement position, and a temperature sensor is mounted at an aircraft afterbody dynamic temperature load measurement position, the pressure sensor and the temperature sensor are installed on the aircraft afterbody through the screws, screw rods of the screws are screwed on the aircraft afterbody, grooves are formed in the heads of the screws, and the pressure sensor and the temperature sensor are arranged in the grooves in the heads of the screws. The dynamic aerodynamic load and the dynamic temperature load of the aircraft afterbody are measured through a pressure sensor and a temperature sensor at the same time, the dynamic temperature load of the aircraft afterbody is measured through the temperature sensor, the dynamic temperature load comprises dynamic heat flow and wall surface temperature, and the corresponding relation between the actual temperature of the dynamic heat flow and the wall surface and the temperature measured by the temperature sensor is established. And correcting the measured temperature to obtain the actual temperature of the wall surface.
