飞机红外特征研究

Study of Infrared Signatures of Aircraft

红外成像探测和跟踪技术促使飞机红外隐身技术得到了相应的发展。为了达到飞机隐身的目的,首先应对飞机的红外特性进行研究。本文分析了影响飞机红外辐射特性的主要因素,并从工程计算与实际应用的需求出发,在以往计算方法的基础上,通过优化比较,给出了一种计算尾流、尾喷管、蒙皮和蒙皮反射阳光的红外辐射的方法。最后通过计算表明,该方法实用可靠,符合工程计算与应用的要求。

The aircraft stealth technology is developed correspondingly with the development of infrared imaging detection and tracking technologies. To let an aircraft be stealth, the infrared signatures of it should be analyzed. The main factors which have influence on infrared radiation characteristics are analyzed. On the basis of the traditional calculation methods, a method for calculating the infrared radiation from the exhaust gas, nozzle and skin of an aircraft and the solar radiation reflected from the aircraft skin is given. The calculation result shows that the calculation method is practical and reliable and can meet the requirements of engineering calculation and practical application.
