The pressurizing device of the liquid oxygen methane rocket comprises a liquid oxygen storage tank and a liquid methane storage tank, wherein the liquid oxygen storage tank is provided with a pressurized gas inlet; and the liquid methane storage tank is internally provided with a pressurized gas cylinder, and the pressurized gas cylinder communicates to the pressurized gas inlet through a pipeline. The invention providesthe pressurizing device of the liquid oxygen methane rocket and the liquid oxygen methane rocket with lower cost on a basis of guaranteeing the safety.

Description

technical field [0001] The invention relates to the technical field of liquid rockets, in particular to a liquid oxygen methane rocket booster and a liquid oxygen methane rocket. Background technique [0002] Liquid oxygen methane propellant has the characteristics of wide sources, low cost, non-toxic and environmentally friendly, and high performance. It is more suitable for repeated use and the use requirements of low-cost rocket vehicles. It is one of the ideal liquid power options for future space vehicles. At present, many aerospace companies at home and abroad are developing liquid oxygen methane rockets and rocket engines. The pressurization system is used to provide the pressure of the air pillow of the liquid rocket propellant tank. The pressurized gas enters the propellant tank, expands to occupy the space after the propellant is discharged, and generates working pressure on the liquid propellant. On the one hand, it meets the needs of the engine during flight. Th...
