飞机地面静态红外辐射强度测试

Measurement of Static Infrared Radiation Intensity of Aircraft Ground

根据飞机整机地面静态红外辐射强度测试的基本要求,利用中波热像仪(2~5μm)和长波热像仪(7.5~13μm)对处于地面静态下的某型飞机在发动机关闭、低速运转、中速运转和高速运转四种不同工况下的半周向红外辐射图像进行了拍摄,拍摄水平角度为0°。利用软件对得到的图像进行了计算,得到飞机的红外辐射强度,对辐射强度分布状况进行了分析。

According to the basic requirements of static airplane infrared radiation tests,the flank infrared imagines of a certain airplane which is on the ground are acquired with medium-wave(2-5μm)and long-wave(7.5-13μm)IR camera.In the process of shooting,the engine of airplane is in four different conditions:shutoff,low-speed running,medium-speed running and high-speed running.The horizontal angle of shooting is 0°.The infrared imagines are calculated with self-developed software,the infrared radiation intensity of the plane is obtained and the infrared radiation distribution is analyzed.
