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。
In this thesis , many state - of - the - art schemes of force measure system are introduced , analyzed and compared at first . then the universal model used is summarized , which shows that the dynamic thrust measuring technology is feasible 该技术的研究对于发动机在空间推进系统中最有效地工作、节省有限的星上能源、提高卫星等航天器的工作寿命等有着积极的推动意义。
Finally , by practical test , experimental data obtained show that the dynamic thrust measuring system is dramatically available and successful . especially , it shows that when the impulse width is 20ms and the duty ratio is 1 : 3 , the measured results are stable and reliable . hence , the system designed here can meat the test requirements of the actual applications , and the technology studied in the thesis also give a good foundation to future research work 最后,系统建成以后,通过多次调试试车、考核试车和实际型号试车的考核,试车结果表明,该系统的设计是成功的,动态推力数据稳定、可靠,可满足发动机以20ms脉宽工作,占空比为1 : 3的情况下,进行发动机的动态推力性能指标测试,满足实际应用的需求,为进一步进行动态推力测试技术研究奠定了良好的基础。
