本文介绍了飞机和发动机的红外信号以及飞机在格斗中这些信号与飞机生存性的关系。介绍了燃气涡轮发动机在野外静止试验和风洞模拟试验时测量红外辐射信号的技术。提出了红外信号测量用的检测仪表和数据分析方法,检测仪表具有波段、光谱和空间分布的特性。也介绍了预估飞机飞行中信号的技术,讨论了这些信号在空战模拟器中的应用。 This article describes the infrared signals of aircraft and engines as well as the relationship of these signals to the survivability of the aircraft in combat. This paper introduces the technology of gas turbine engine to measure the infrared radiation signal in the field static test and wind tunnel simulation test. A measuring instrument and data analysis method for infrared signal measurement are proposed. The instrumentation has the characteristics of wavelength band, spectrum and spatial distribution. The technique of estimating signals in aircraft flight is also introduced, and the application of these signals in air combat simulators is discussed.
