Study on Infrared Images Simulation of Fighter Aircraft

Infrared radiation images of aircraft generated by simulation are the important data source for fighter target identification. Considering a fighter aircraft as the research object, infrared radiation characteristics of the whole aircraft was analyzed comprehensively in this paper. Numerical simulation of the temperature distribution of aircraft skin and exhaust plume was carried out by the commercial CFD software Fluent. The infrared radiation of aircraft was simulated at different observation positions and during different detection waveband. The result showed the difference of infrared images and radiation intensity in different wave bands and different directions, which was compared and analyzed. The research achievements offer the simulation models for the study of aircraft's infrared radiation characteristics.
