水平起降航天飞机火箭-冲压-火箭方案概念研究

PRELIMINARY STUDY OF THE ROCKET-RAMJET-ROCKET CONCEPT FOR HTOL SPACE PLANE

本文提出了水平起降、两级入轨航天飞机的火箭-冲压-火箭方案。着重讨论了实现这个方案的推进系统,对冲压发动机采取了提前点火和高空补氧两项关键技术,使本方案具有可行性。在优化了推进系统的基础上,提出本方案航天飞机总体布局和基本尺寸,并给出飞行轨迹。通过质量计算所得的有效载荷比具有先进性。

This paper addresses a rocket-ramjet-rocket concept for HTOL/TSTO space plane. Emphasis is laid on discussion of propulsion system for this concept. To ramjet, two key measures-earlier ignition and oxygen replenishment at high altitude are taken, so that the concept is feasible. Flight trajectory of the plane is given as well as its configuration and overall dimension. Based on the mass estimation, the calculated pay-load ratio is rather advanced by using technologies of the nineties.
