| Abstract: | This paper presents an experimental method to measure surface temperature field distribution of airplane under solar radiation by airplane downsizing model,and suggests a method to realize analogue display of 3 dimensions for temperature field distribution by finite element method.This method may avoid the influence of the uncontrollable intensity of natural solar radiation and the variable ambient temperature under field measuring condition,and provide an efficient method to validate the theoretical model of surface temperature field distribution of airplane under solar radiation and to measure it by experiment.It will be beneficial to the research of infrared characteristics and calendar life for airplane. |
