Ballistic trajectory-based ground test temperature measurement method in aircraft ground thermal intensity test

The invention discloses a trajectory-based ground test temperature measurement method in an aircraft ground thermal intensity test, and relates to the technical field of aircraft testing, and the method comprises the following steps: S1, selecting an infrared point temperature instrument; s2, installing an infrared point temperature instrument; s3, temperature calibration; s4, determining an exchange temperature point; and S5, determining a final measurement value. According to the ground test temperature measurement method, the infrared point temperature instrument can measure the flight trajectory of an aircraft from the normal temperature condition of 20-30 DEG C to the high temperature condition of 2000 DEG C or above, the application of the infrared point temperature instrument in the ground thermal intensity is expanded, the temperature measurement accuracy is greatly improved, and the method can be popularized to the non-contact measurement fields of metal smelting, the nuclear industry, aerospace and
