Abstract

The invention discloses a supply system applicable to large scale liquid oxygen methane rocket engine tests. The supply system avoids repeated construction of an oxidizing agent supply system, and reduces the cost; in the supply system, methane and liquid methane can be supplied at the same time, large scale rocket engine tests with gas and liquid methane being mixed can be carried out, and regeneration and cooling engine fuel performance tests can be performed at low cost; large scale rocket engine tests at different methane injection temperatures can be stably and efficiently carried out through a mixer; in the supply system, liquid nitrogen is adopted to perform low-temperature pipeline precooling, and the supply system has the advantages of high safety and low cost. On the basis of thesupply system, the invention further provides a rocket based on the supply system applicable to large scale liquid oxygen methane rocket engine tests.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to a test supply system and a rocket suitable for a large liquid oxygen methane rocket engine. Background technique [0002] 1. Large-scale liquid rocket engines have a huge demand in the aerospace field. Human exploration of the moon or landing on Mars in the future will require high-thrust liquid rocket engines as support. Liquid oxygen / methane liquid rocket engines have high specific impulse, low cost, The advantages of low carbon deposition, cooling without coking, good environmental performance, and reusability are the focus of research in the field of reusable launch vehicles and large liquid booster power devices today. However, at present, there are few related tests on liquid oxygen / methane rocket engines, and further research is still needed. The existing test system carries out liquid oxygen / liquid methane and liquid oxygen / gas methane tests separately, and the test system has p...
