【摘要】 研究了应用于空天飞机的液体空气循环发动机。介绍了提高空气液化比的几种方法，如：液氢，液氧储箱循环，液氧喷洒，液态空气喷洒。以能量平衡为基础，计算了液体循环发动机的循环参数。结果表明综合采用以上方法可以使液化比提高约６５％。更多还原

【Abstract】 he concept of liquified air cycle engine (LACE) for space vehicles has been studied.To improve air liquification of LACE, several kinds of methods such as LH2, LOX tank return, LOXspray, liquid air spray have been introduced. Based on the relation of energy equilibrium, LACE cycleparameters calculation has been done. The result shows that those methods discribed above can improve the liquification by about 65 %.更多还原
