    摘要:

    为解决空天飞机动力问题,提出一种新型带液化空气循环子系统的吸气式-火箭组合循环(ARCC)概念。该组合循环发动机集涡轮、冲压及火箭发动机优点于一身,在吸气式发动机工作过程中通过液化空气循环子系统液化大气中的氧气,存储供氢氧火箭发动机工作时使用,自身携带少量或不带氧化剂,因而经济性较好。为提高液化空气循环子系统液化比,采用多种措施设计一种新型液化空气循环子系统。计算了液化空气循环热力过程和ARCC发动机比冲性能,结果表明:液化空气循环子系统在整个吸气式飞行过程中具有较高液化比;ARCC发动机在不同的飞行条件下都能得到良好比冲特性,经济性好。

    Abstract:

    To overcome the propulsion difficulties of aerospace plane, a new concept air-breathing rocket combined cycle (ARCC) with LACE subsystem is presented. This combined engine integrates the turbojet, ramjet and rocket engines into one propulsion system. When the air-breathing propulsion works, the LACE subsystem liquefies the oxygen from the atmosphere and stores it in a liquid oxygen tank as propellant of the liquid hydrogen/liquid oxygen rocket. As it takes a little liquid oxygen or even none from ground, the aerospace plane is much economical. To enhance the LACE subsystem liquefaction ratio, a new cycle of LACE subsystem is designed with several measures adopted. The thermal processes of the LACE subsystem and the specific impulse performance of ARCC are calculated. The results show that the liquefaction ratio of the LACE subsystem is very high at most of the air-breathing flight states and the specific impulse performance of ARCC is excellent at most of the flying conditions.
