Hydrogen peroxide and kerosene self-pressurization power system

Abstract

The invention discloses a hydrogen peroxide and kerosene self-pressurization power system. The system comprises a thrust chamber used for generating thrust through ignition and combustion, a hydrogenperoxide storage box used for providing hydrogen peroxide for the thrust chamber, a kerosene storage box used for providing kerosene for the thrust chamber and a gas generator used for injecting gas into the hydrogen peroxide storage box and the kerosene storage box. The hydrogen peroxide storage box is further used for providing hydrogen peroxide for the gas generator. The hydrogen peroxide storage box is used for providing hydrogen peroxide for the gas generator, hydrogen peroxide is combusted in the gas generator to generate gas to be injected into the hydrogen peroxide storage box and thekerosene storage box, the hydrogen peroxide storage box and the kerosene storage box are pressurized, and hydrogen peroxide and kerosene in the hydrogen peroxide storage box and the kerosene storage box are injected into the thrust chamber to be ignited and combusted to provide drive force for an engine. The system integration degree is high, the system mass is relieved, and safety and maintainability of the hydrogen peroxide and kerosene self-pressurization power system are improved.

Description

technical field [0001] The invention belongs to the field of pump pressure engines, in particular to a hydrogen peroxide kerosene self-supercharging power system. Background technique [0002] The liquid rocket engine is an important foundation of the current launch vehicle, which is of great significance for space launch and deep space exploration missions. In order to further reduce the launch cost and increase the launch frequency, new requirements are put forward for the repeated use and convenience of the rocket engine; as a commonly used propellant combination, hydrogen peroxide kerosene is storable at room temperature and non-toxic and non-polluting. It has the characteristics of high density specific impulse and easy storage, which can bring convenience in storage and filling, and greatly reduce the launch preparation time. Therefore, the research on hydrogen peroxide kerosene power system has received extensive attention. [0003] For a power system with a small th...

[0004] But on the other hand, the constant pressure extrusion power system solution needs to carry high-pressure gas cylinders. During the storage process, high-pressure gas cylinders are poor in safety and maintenance, which brings certain dangers to operators and increases the use and maintenance. At the same time, due to the normal temperature gas pressurization, the pressurization efficiency is low, resulting in a heavier system structure, which leads to a reduction in the payload mass of the aircraft
