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.
