Hydrogen peroxide propellant filling and supercharging operating platform

Abstract

The invention discloses a hydrogen peroxide propellant filling and supercharging operating platform. The hydrogen peroxide propellant filling and supercharging operating platform aims at a hybrid rocket motor or a liquid rocket motor, fills hydrogen peroxide into a motor storage tank, and supercharges a motor gas storage bottle and the motor storage tank. The hybrid rocket motor or the liquid rocket motor adopts an extruding type supercharging delivery method and adopts the hydrogen peroxide as propellant. The hydrogen peroxide propellant filling and supercharging operating platform comprises a high pressure supercharging gas circuit, a low pressure supercharging gas circuit and a hydrogen peroxide filling gas circuit. The high pressure supercharging gas circuit, the low pressure supercharging gas circuit and the hydrogen peroxide filling gas circuit respectively conduct high pressure supercharging to the motor gas storage bottle, conduct low pressure supercharging to the motor gas storage bottle or / and the storage tank, and adopts a suction type scheme to fill the hydrogen peroxide propellant into the storage tank. When gas pressure of the motor gas storage bottle or the storage tank is larger than a safe value, emergent pressure relief is further capable of being conducted. The hydrogen peroxide propellant filling and supercharging operating platform has the advantages of simultaneously having hydrogen peroxide filling, high pressure supercharging and low pressure supercharging functions, and being simple in structure, small in floor area, and saving in high pressure supercharging gas consumption of a high pressure bottle group in the high pressure supercharging process.

Description

Technical field [0001] The present invention relates to the technical field of rocket engine testing. Specifically, it relates to a hybrid rocket or liquid rocket engine that uses an squeeze pressurized delivery method and uses hydrogen peroxide as a propellant to fill the engine tank with peroxide Hydrogen, and pressurize the engine gas cylinder and storage tank. Background technique [0002] Hydrogen peroxide has the characteristics of low toxicity, high density, and low saturated vapor pressure, and the decomposition products are only water and oxygen. It can be used as a single-component propellant or as an oxidant in a two-component propellant. Its high-density specific impulse, green non-toxic, storage at room temperature, high fuel mixing ratio and other performances are particularly suitable for mission requirements such as high thrust, rapid response, repeated use, and long-term on-orbit operation. It is considered to be the current propellant toward non-toxicity One of...
