摘要
文中介绍了一种改进型逆升压空气循环(TTC)吊舱环控系统,该系统采用TTC双涡轮并行制冷技术。结合试验与仿真分析结果研究了该系统的制冷性能,主要结论有:相比传统TTC环控系统,TTC双涡轮并行制冷环控系统制冷量增幅超过20%,高空工况制冷量增幅超过60%;当飞行高度为10 km、飞行马赫数在0.4~1.0范围内时,随马赫数的增加,环控系统制冷量先增加后减小,在Ma=0.9时,制冷量达到最大;当Ma=0.75时,在飞行高度0~15 km范围内,随高度的增加,环控系统制冷量先增加后减小,在高度达到6 km时,制冷量达到最大。
A reformative turbo-turbo-compressor （TFC） environment control system （ECS）, which adopts a new teehnology named double-turbo parallel refrigeration, has been explored in this paper. The systems solutions have been introduced firstly, then the capability analysis of the new system is studied by testing and simulation investigation. The conclusions are as follows ： compared to the traditional ECS of Trc, refrigerating capacity in- crease of the double-turbo parallel refrigeration ECS of Trc is more than 20% and more than 60% at high altitude ; when the flight altitude H = 1 0 km , along with the increase of the flight Mach number in range of 0.4 - 1.0, the refrigerating eapaeity of the system increases first and then deereases. And the maximum refriger- ating capacity appears at Ma = 0.9 ; when the flight Mach number is 0.75, along with the increase of the flight altitude in range of 0 - 15 km, the refrigerating capacity of the system increases first and then decreases. And the maximum refrigerating capacity appears at the flight height of 6 km.
