现代军用飞机为提高战斗力,越来越多地外挂装备有各种电子、激光、红外、雷达等设备的吊舱。这些设备的性能和可靠性对温度、湿度等环境条件有强烈的依赖关系。为保证这些设备在干燥、清洁、温度适宜的环境中可靠工作,必须在吊舱中装备环境控制系统。为解决吊舱设备的冷却通风问题,早期国外曾经有人提出将载机环控系统冷气直接引入电子吊舱的方案,但目前除俄罗斯采用此方案外,其他国家均未采用。其原因一是载机自身环控系统冷却能力有限,不能满足日益增长 Modern military aircraft to improve combat effectiveness, more and more plug-in equipped with a variety of electronic, laser, infrared, radar and other equipment pods. The performance and reliability of these devices have a strong dependency on environmental conditions such as temperature and humidity. To ensure reliable operation of these devices in dry, clean and temperature-friendly environments, environmental control systems must be equipped in the pods. In order to solve the problem of cooling ventilation of pod equipment, some people in foreign countries proposed to introduce air-conditioners in air-conditioners into electronic pods directly in early days. However, no other countries have adopted this solution except Russia. The reason is that the carrier’s own control system has limited cooling capacity and can not meet the growing demand
