Abstract

The invention discloses an oxygen supply system for an engine reusing test. The oxygen supply system comprises an oxygen source system, an oxygen transporting system and an oxygen distribution table. In the oxygen source system, a process of preparing oxygen through a liquid oxygen vaporization method is adopted, and the utilization rate of raw liquid oxygen materials is improved. Through the real-time monitoring of a pressure sensor, the whole process can be safely performed. In the oxygen transporting system, measures are taken for control over the flow speed of an oxygen pipeline, a mode of connecting two pneumatic cutoff valves in parallel is adopted, and a small-aperture pneumatic cutoff valve is turned on in advance to be served as a pilot valve. The pressures of two ends of a large-aperture pneumatic cutoff valve are balanced, and the large-aperture pneumatic cutoff valve is turned on, so that a good effect of reducing the flow speed of high-pressure oxygen can be achieved. In the oxygen transporting system, a scheme of three main paths and an ignition path is adopted. A pipeline assembly can be reasonably selected according to test requirements.

Description

Technical field

[0001] The invention relates to an oxygen supply system for liquid rocket engine testing, which belongs to the technical field of aerospace engines. Specifically, it is an oxygen supply system with high safety factor, high control precision, and remote control performance. Background technique

[0002] At present, in the field of repeated use of aerospace engine tests, the supply system is required to be able to supply propellant multiple times for a long time. The realization of the propellant supply system is the guarantee for the successful engine test, and the design of the oxidant supply system is an important content. As a common oxidant, oxygen occupies an important position in the field of engine propellants. During the engine test, the oxygen supply is maintained at a high pressure. At this time, the oxygen has strong oxidizing properties. In the process of high-speed flow, it is easy to rub against the oil and ester substances in the pipeline and ignite...
