摘要: 机载制冷系统可为电子设备提供制冷.由于机载吊舱的特点,机载吊舱制冷系统的结构和工作原理与传统机载制冷系统差别很大.介绍了现有机载吊舱空气循环制冷系统的不同方案,针对其制冷量偏低、无地面制冷能力等不足,提出了2?kW等级高速电机驱动的逆升压式空气循环制冷方案,详细阐述了其设计思想、工作原理和组件结构设计方法,并进行了制冷性能及性能代偿损失计算.结果表明,这种新型系统结构紧凑,耗电量小,工作可靠,可提高制冷性能.该系统受飞机飞行状态影响小,可提供地面冷却能力,是一种较有应用前景的机载吊舱环境控制系统.

Abstract: Refrigerating system used on aircraft can provide refrigeration for electronic equipments. Because of the special characters of aircraft pod, there are many differences on framework and working theory between refrigerating system used on aircraft pod and the one used on normal aircraft. Several air cycle refrigerating schemes designed for aircraft pod were introduced. Design concepts, working theories of a reverse bootstrap air cycle refrigerating system driven by 2kW-powered high-speed electric machine were described. Component structural design methods were discussed. Refrigerating performance and performance penalty calculations were given. The results show that the new system has a compact structure and low power consumption. It works reliably and can increase the refrigerating performance. This system is affected by aircraft flight states lightly and can provide cooling capacity when the aircraft is on the ground. It's a promising environmental control system for aircraft pod.
