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.
