Embodiment Construction
[0044] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0045] The invention is a test supply system suitable for large-scale cryogenic liquid rocket engines, including a fuel pressurization system, an oxidant pressurization system, a fuel delivery system and an oxidant delivery system.
[0046]The fuel pressurization system and the oxidant pressurization system are undertaken by the nitrogen system. The nitrogen system is also responsible for the control gas for opening all pneumatic valves of the overall system and the purge gas during the test. figure 1 In the middle, the high-pressure nitrogen storage tank A01 is connected with the manual shut-off valve A00, the pressure sensor A02, the pneumatic shut-off valve A04, and the manual shut-off valve A03. One end of the filter A05 is connected with the pneumatic shut-off valve A04 and the manual shut-off valve A03. Connect the manual shut-off valve A06 and...
