Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0014] figure 1 It is a schematic diagram of a longitudinal section structure of an embodiment of the present invention, figure 2 is its injector injection panel view.

[0015] As shown in the figure, this embodiment is composed of a solenoid valve 1, an injector 2, a catalytic decomposition chamber 3, and a spray pipe 4 connected in sequence. The solenoid valve 1 delivers hydrogen peroxide to the injector 2, and the hydrogen peroxide is transported through the injector 2 and injected into the catalytic decomposition chamber 3. Under the action of the catalyst, the hydrogen peroxide is decomposed into high-temperature and high-pressure gas, and then discharged by the nozzle 4 to generate thrust . The mass concentration of the hydrogen peroxide monopropellant used in this embodiment is 85% or 90%.

[0016] The injector 2 adopts a shower he...

Abstract

The invention discloses a small-thrust single-component hydrogen peroxide rocket engine applied to space vehicles and aircrafts, which comprises a solenoid valve, an injector, a catalytic decomposition chamber and a nozzle connected in sequence. The solenoid valve delivers hydrogen peroxide to the injector. The hydrogen peroxide is transported through the injector and injected into the catalytic decomposition chamber. Under the action of the catalyst, it is decomposed into high-temperature and high-pressure gas, and then discharged from the nozzle to generate thrust. The invention uses high-concentration hydrogen peroxide as the propellant of the single-component attitude control rocket engine, which can replace the existing conventional toxic hydrazine single-component propellant, and achieves the beneficial effect of making the single-component attitude control engine non-toxic.

Description

technical field [0001] The invention relates to the technical field of space vehicle engines, in particular to a small-thrust single-component hydrogen peroxide rocket engine. Background technique [0002] Single element rocket engine, because of its simple system and high performance, is widely used in domestic and foreign launch vehicle power systems, spacecraft, space stations and other spacecraft attitude and orbit control systems. At present, the vast majority of small-thrust monolithic rocket engines for spacecraft use toxic hydrazine propellants. These toxic propellants have caused great harm to the natural environment and human health during production, storage, transportation and use, and the manufacturing cost is also very high. Non-toxic, non-polluting, high-performance, and cheap propulsion systems are the main directions of research in the field of spacecraft propulsion. [0003] Hydrogen peroxide is a traditional non-toxic monopropellant, and its decompositio...
