Embodiment Construction
[0033] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0034] The present invention is a hydrogen peroxide solid-liquid rocket engine self-pressurization conveying system, comprising: a booster solenoid valve 1, a safety valve 2, a storage tank 3, a storage tank pressure sensor 4, a storage tank filling discharge valve 5, an electric Explosion valve 6, liquid path tee 7, catalytic path solenoid valve 8, catalytic path flow control valve 9, catalytic bed 10, gas path tee 11, pressure reducer 12, main path solenoid valve 13, gas booster pump 14, Main road flow control valve 15.
[0035] Hydrogen peroxide is stored in the storage tank 3. After receiving the opening instruction, the electric explosion valve 6 is opened, and the hydrogen peroxide flows into the liquid path tee 7 and is divided into two paths. One path flows into the catalytic path solenoid valve 8 inlet, and the other path flows into the main ...

The invention discloses a self-pressurization conveying system of a hydrogen peroxide solid-liquid rocket engine, and is suitable for a solid-liquid rocket engine. The system comprises a pressurization electromagnetic valve, a safety valve, a storage box, a storage box pressure sensor, a storage box injection and out-flow valve, an electric explosion valve, a liquid way tee joint, a catalytic way electromagnetic valve, a catalytic way flow control valve, a catalysis bed, a gas way tee joint, a pressure reducer, a main way electromagnetic valve, a gas pressurization pump, a main way flow control valve, a pipeline and the like. The self-pressurization conveying system of the hydrogen peroxide solid-liquid rocket engine is used for pressurization conveying of hydrogen peroxide of the solid-liquid rocket engine, a high-pressure gas cylinder and a subsidiary pipeline are not utilized, the size and the weight of the conveying system are thus reduced, and the danger of the solid-liquid rocket is reduced; and in the self-pressurization conveying system of the hydrogen peroxide solid-liquid rocket engine, the extrusion pressure of the storage box is lower, the weight of the storage box is reduced, and the performances of the engine are improved.
Description
technical field [0001] The invention relates to a hydrogen peroxide solid-liquid rocket engine self-pressurization conveying system, which belongs to the field of solid-liquid rocket engines. Background technique [0002] The hydrogen peroxide solid-liquid rocket engine has the advantages of high specific impulse, easy adjustment of thrust, and environmental friendliness. [0003] Small and medium-sized solid-liquid rocket engines often use extrusion delivery systems, and high-pressure gas cylinders are often used to store gas to pressurize the storage tank. The pressure of the storage tank and gas cylinder is high, and the pressure of the combustion chamber is limited by the pressure of the storage tank. When the extrusion conveying system is used in a solid-liquid rocket engine for a long time or at a high chamber pressure, the structural mass of the conveying system is heavy, which affects the performance of the solid-liquid rocket engine.
