Problems solved by technology

Therefore, the supply system needs to meet the above two test requirements at the same time, which makes it very difficult to switch the supply system. In addition, the general method is to use a pump that provides a high-pressure inlet of the thrust chamber and a large flow rate. Manufacturers have raised great manufacturing difficulties, and the domestic market can hardly meet the requirements

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...

Abstract

The invention discloses a large cryogenic liquid rocket engine test bed supply system. The system comprises a fuel pressurization system, an oxidizing agent pressurization system, a fuel transport system and an oxidizing agent transport system. According to the system, propellant is pressurized through a gas supercharging method, and the stability and reliability of liquid flow in the engine testing process are guaranteed; the domestic normally-used pump pressurization method is not adopted and has the defects that the output flow of liquid is in an impulse mode, vibration is strong and difficulty is caused in the testing process, so the gas supercharging method has high adaptability to the system; the function that liquid propellant is converted into gas propellant is expanded, the requirements of other testing systems for the gas propellant can be met in future, and the multifunctionality of the testing system is greatly expanded.

Description

technical field [0001] The present invention is suitable for a large-scale low-temperature liquid rocket engine test bed supply system, and its main application field is the low-temperature liquid oxygen / methane engine test platform that can be used by reusable engines in the future. Background technique [0002] Large-scale liquid rocket engines have a huge demand in the field of aerospace. Human exploration of the moon or future landing on Mars require high-thrust liquid rocket engines as support. Among them, the reusability of the engine has become an urgent problem to be solved. Liquid oxygen / methane As a reusable propellant for future engines, it has potentially strong competitiveness. The construction of a test system based on liquid oxygen / methane has become one of the problems that must be solved. [0003] A high-thrust engine is generally composed of a turbopump system and a thrust chamber, so the supply system should simultaneously meet the requirements of the sep...
