太阳辐射作用下的飞机表面温场分布实验研究

摘要

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.%提出一种通过缩比模型测试飞机在太阳辐射作用下的表面温度场分布,进而通过有限元方法实现太阳辐射温场的三维模拟显示的实验方法.该方法避免了外场测试条件中自然日光辐射强度不可控和环境温度变化的影响,为飞机在太阳辐射作用下的表面温场理论模型验证和实测提供一种有效的方法,对飞机红外特性、日历寿命等研究具有借鉴意义.
