| 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 %. |
