发动机尾气冷凝水回收技术研究

Research on Condensation of Water Recovery from Engine Exhaust

基于长航时对流层飞艇重浮力平衡的现实需求,通过对发动机尾气状态和冷凝出水过程的分析,提出了发动机尾气冷凝水出水量的计算方法;开展地面试验对冷凝水回收系统原理和计算方法进行验证;通过装艇系统设备选型对工程应用可行性进行探讨。结果表明,计算方法合理,该技术是解决对流层飞艇长航时飞行较为切实可行的方法。

According to the realistic demand of weight lift balance of troposphere long endurance airship,through the analyzed results of the condition of the engine exhaust and process of condensation. The calculation method of the amount of recovering condensation water from engine exhaust is suggested,the principle and method is proved by ground testing,The feasibility of engineering application is discussed by airship system equipment selecting. The result shows that this technique is an available method to solve the problem of long endurance flight for troposphere airship.
