摘要
Abstract
An aircraft geometric model is established for unstructured grid processing, and numerical simulation of the aerodynamic heat in the external flow field is carried out using the Fluent software. Considering the influence of nozzle and plume radiation on the aircraft temperature, the temperature distribution data of aircraft surface is obtained. The model for calculating infrared radiation of aircraft fuselage is established based on the reverse Monte Carlo method, the infrared irradiance of plume is calculated based on the radiative transfer equation, and the infrared image of the airplane is obtained using the method of gray level transformation.关键词
