Infrared radiation characteristic testing and evaluating technology of aero-engine

The infrared radiation characteristic testing research of aero-engine is the significant basis for infrared stealth design and improvement of plane and aero-engine. According to the requirement of infrared radiation characteristic testing,the project on the areo-engine test bed was proposed from four aspects such as platform,testing system,testing method and error control. The infrared radiation characteristic testing of aero-engine was carried out and the available data were acquired as this project. Through data processing and evaluating,the results shows that aero-engine infrared radiation characteristic is directional.
