The invention provides a metal plate laser irradiation thermal examination scaling test design method under high-speed airflow. The method comprises the following steps: (1) deriving a similarity criterion of a metal plate under high-speed airflow and laser irradiation based on a similarity theory and a dimensional analysis method; (2) judging whether the ground test environment temperature can reproduce the real high-altitude flight environment temperature or not; (3) selecting a corresponding reasonable scaling strategy and a scale law in combination with the actual condition of the test; (4) adjusting scale factors of the environmental parameters according to a scale law, and performing a thermal assessment test of the scaling model; and (5) on the basis of similarity transformation and numerical value correction, predicting an original model result through a scaling model test result, and obtaining thermal response characteristics of a real structure. According to the invention, the thermal assessment tes
