摘要

针对一种环保推进剂组合

建立了亚轨道飞行器设计仿真模型、质量模型和弹道模型

以燃烧室压强、余氧系数及喷管出口截面压强为分析变量

对亚轨道飞行器的性能进行了分析.所得结论表明:在给定飞行任务下

为提高亚轨道飞行器性能

燃烧室压强越高越有利;最佳余氧系数在0.99处取得;喷管面积扩张比受到箭体外径及工艺水平等限制

在条件允许的情况下

尽量取大.研究结果为其他同类亚轨道飞行器的系统方案研究提供参考.

Abstract

For a environment propellant group

the simulation model

mass model and orbit model of adjacent space aircraft were established.By setting combustion chamber pressure

ample oxygen coefficient and nozzle exit pressure as variables

the performance of adjacent space aircraft was analyzed.The results show that it will be better with higher combustion chamber pressure under specific task for improving adjacent space aircraft performance.The best ample oxygen coefficient can be achieved at 0.99.If permitted

the nozzle area expansion ratio deployed should be as big as possible

since it is limited by rocket outer diameter and technology level

etc.The correlation study could provide a guidance for the system project study of other similar adjacent space aircrafts.
