Abstract

The invention relates to a liquid rocket engine environment simulation test, in particular to a thermal test method for heat flux density in a vacuum environment of an attitude control engine, to solve the problem of the simulation test in the heat flux density heat test test of the existing attitude control engine in the environmental simulation test cabin. In the cabin, there are problems such as long vacuuming time, high ambient humidity, large error in heat flux loading, non-directional heat radiation, poor cooling effect and unstable propellant supply. The technical solution adopted in the present invention is: a thermal test method for heat flux density in a vacuum environment of an attitude control engine, comprising the following steps: step 1, installation of a thermal environment device; step 2, vacuumizing and cooling the vacuum chamber; Step 3. Calibrate the heat flux of the attitude control engine simulation part. Step 4. Replace the attitude control engine simulation part with the attitude control engine to be tested and install it in the vacuum chamber to conduct a thermal test on the heat flux density of the attitude control engine.

Description

technical field [0001] The invention relates to an environmental simulation test of a liquid rocket engine, in particular to a thermal test method for heat flux density in a vacuum environment of an attitude control engine. Background technique [0002] The 2000N thrust attitude control engine is the main power of an aircraft's orbit control cabin, and its performance and reliability need to be verified in complex environments such as heat tests in thermal vacuum coupling environments. At present, the attitude and orbit control power system only conducts individual test verification and assessment of mechanical environment, thermal environment, or thrust chamber heat test environment, and cannot carry out comprehensive test verification in real complex environments. Therefore, according to the test requirements, a 2000N attitude control engine is established at a height of 76km from the ground and a heat flux of 340kWm 2 The thermal test test simulates the high-altitude env...
