Abstract

The aviation jet engine is the main infrared radiation source of aircraft ,and also the main target for the detection and attack of infrared precision guided weapon systems. The study of spectral radiation characteristics of jet engine exhaust plume is of great significance for the detection, early warning and identification. This paper introduces a test method for the spectral radiance of aero-engine exhaust plume, and analyzes the uncertainty of the measurement results. The test results show that this method can effectively obtain the infrared spectral radiance of the exhaust plume, and the measurement uncertainty is 19.54%. It can effectively obtain the infrared spectrum radiation data of the engine exhaust plume, and provide test parameter support for the infrared spectrum radiation characteristics of the jet engine, the aircraft infrared stealth design, the anti-stealth detection, the infrared stealth technology research and the infrared seeker design.
