- 摘要:
- 为有效考核氢氧火箭发动机的在轨飞行状态，需要在地面环境模拟发动机的摇摆工作情况。水平试验台承担氢氧发动机地面摇摆试验时，涉及地面热防护、推力测量系统防护、摇摆测控系统指令实时循环发送与更新、测控系统远程控制等4项关键技术。围绕上述4个方面，对氢氧发动机地面摇摆试验技术展开研究。采用数值仿真计算、经验公式、流程图设计、硬件搭建、软件程序编制等多元化的手段，结合实际情况确定输入输出条件，推导出相关结论。试验验证结果证明：摇摆试验地面热防护、推力测量系统防护具有简单易行、防护效果良好的特点，具有较好的工程实用价值。该技术在国内尚属首次应用，已成功申报一项国防专利。
- Abstract:
- It is necessary for ground test to check the swing status of LOX/LH2 rocket engine in orbit. When the horizontal test system is used for ground test of swing status of LOX/LH2 rocket engine, four key technologies (ground heat protection, thrust force measuring system protection, real-time data cyclic sending and update of swing control system and system remote control) are involved. Aiming at the four aspects, the ground swing test technology of LOX/LH2 rocket engine was studied. The numerical simulation calculation, empirical formula, flow chart design, hardware connection and software programming are employed to determine the input/output conditions according to the actual situation, and then derive the relevant conclusion. The ground heat protection and thrust force measuring system protection national defence was achieved for it. It was applied in the test. The test and verification results prove that the technology is reasonable, and can provide reference for the similar test.
