Abstract
The study of the infrared radiation characteristics of dual-engine fighters provides theoretical support for the stealth design of future fighters. This paper takes a dual-engine fighter as the research object and uses the Reverse Monte Carlo Method (RMCM) to carry out the numerical simulation of its infrared radiation characteristics. The results show that: in the 3-5μm band, with the Mach number increasing, the peak infrared radiation intensity increases, and the solid radiation accounts for about 90% of the total radiation at a detection angle of 180°; in the 8-14μm band, the infrared radiation intensity is distributed in the shape of "8". When the Mach number increases, the infrared radiation intensity of the abdomen of the fuselage is higher than that of the back.
