Abstract

In order to solve the problems of the existing liquid oxygen kerosene engine based on the high-pressure helium supercharging system that the price is expensive, the pressurized working fluid is carried on the ground, and the consumption is large, the present invention provides a liquid oxygen kerosene engine propellant combination based on gas-oxygen and gas-hydrogen working fluid Pressurization system, including liquid oxygen storage tank, kerosene storage tank, gas-hydrogen pressurization unit for pressurizing kerosene storage tank and gas-oxygen pressurization unit for pressurizing liquid oxygen storage tank; gas-oxygen pressurization unit It includes an electric booster pump, a gas-oxygen gas generator, a water removal device, a throttle valve group, a high-pressure gas-oxygen storage tank, a third on-off valve and a second pressure-reducing valve arranged in sequence; the outlet of the second pressure-reducing valve connected to the pressurized gas inlet of the liquid oxygen storage tank; the liquid oxygen inlet of the gas-oxygen gas generator is connected to the outlet of the electric booster pump, and the kerosene inlet is connected to the outlet of the kerosene storage tank through the fourth switching valve. The invention uses high-pressure gas hydrogen instead of helium to pressurize the kerosene storage tank, and uses high-pressure gas oxygen to pressurize the liquid oxygen storage tank, thereby significantly reducing the cost.

Description

technical field [0001] The invention relates to a liquid rocket engine booster system, in particular to a liquid oxygen kerosene engine propellant combined booster system based on gas-oxygen and gas-hydrogen working fluids. Background technique [0002] With the improvement of liquid power technology, cryogenic propellants will also be gradually applied to the power systems of long-term space vehicles such as lunar landing and Mars exploration. Most of the existing cryogenic engine supercharging systems based on liquid oxygen and kerosene High-pressure helium is used to pressurize the propellant, but my country is a helium-poor country. As a non-renewable resource, helium is currently mainly dependent on imports and is expensive. Contents of the invention [0003] In order to solve the technical problems of the existing liquid oxygen kerosene engine based on the high-pressure helium supercharging system, which are expensive, and the pressurized working medium is carried on ...
