high-altitude simulation

Numerical study on supersonic ejector of simulated altitude test stand
高空模拟试车台超声速引射器数值研究
Method of test data processing for missile used turbojet - part2 : high altitude simulation test
弹用涡轮喷气发动机试验数据处理方法第2部分:高空模拟试验
The dynamic thrust measure technology for high - altitude simulation test of the attitude control liquid rocket engine was studied in the thesis
本文研究的是姿控发动机高空模拟试车中的动态推力测试技术问题。
When an engine works under the vacuum condition . so existing experimental products can be proof - tested by it and all test results obtained will be used for reference for the aero craft . accordingly , the technology studied in the thesis is quite significative to improve the efficiency of the engines of space propulsion system , economize limited resources on the spacecrafts , and prolong their lives
其目的是建立一个能满足小推力液体火箭发动机动态推力测试的系统,以便能够根据空间推进系统对发动机越来越高的工作性能要求,真实有效地反映发动机在真空环境下的工作状态等,对已经设计和生产出的发动机在高空模拟条件下进行实际测试,从而提供发动机的动态性能指标,为发动机的定型提供试验数据和依据。
