- 为了验证发动机羽流对航天器的综合力、热效应,验证发动机与羽流导流装置的相容性,考核羽流热防护材料性能及防护效果,开展了发动机燃气羽流导流综合验证试验工作。为了完成本次试验,对现有大型高空模拟试验台进行改造,新增试验件结构安装系统、位姿调整系统、温度控制系统,改造真空舱系统、真空抽气系统、测量系统、监控系统及推进剂加注系统等。采用机械真空泵与低温泵组合工作的方式获得试验所需真空环境,利用压电测力仪测量羽流扰动作用力,利用基于六自由度平台模式的位姿调整系统实现相对运动的模拟,试验系统经调试与试验验证满足各项技术要求。通过试验获得了试验验证器所受羽流扰动力数据以及试验验证器表面压力、温度及热流密度等参数分布数据,试验取得成功。
- Abstract:
- A synthetical verification test for engine plume flow guidance was carried out to validate the synthetical force and thermal effect acting on the spacecraft, the compatibility of rocket engine and plume flow guidance device, and the performance and protection effect of the plume flow thermal protection material.In order to perform the test, an existing high altitude simulation test stand was reconfigured, and the test article assembly system, location and attitude control system and temperature control system were newly added, as well as the vacuum chamber system, vacuum pump system, measuring system, monitoring system and propellant filling system were remoulded.The combination mode of mechanical vacuum pumps and cryopumps is adopted to achieve the vacuum environment needed for the test.Force measuring device based on piezo crystal sensor is utilized to measure the plume disturbance force.The location and attitude control system based on six-degrees-of-freedom platform is utilized to simulate the relative motion of the spacecraft.The test result shows the synthetical verification test system of the plume flow guidance meets all of the technical requirements.The plume flow disturbance force data acting on the test article as well as the pressure data, the temperature data, the heat flux data and other parameter distribution data on the test article surface were obtained by the test.The test succeeded.
