Problems solved by technology
The ignition guide is installed in the fuel pipeline system, and the capacity is the dose used for one ignition; the isolation and sealing device is a welded structure, which cannot be replaced after use
The above characteristics determine that the ignition duct can only be used for an engine system that starts once; at the same time, the ignition duct cannot realize the gas-liquid isolation of the ignition agent and the pressurized gas, and cannot realize the liquid supply management under complex overload conditions

The invention relates to a rocket engine ignition agent storage and supply device. The rocket engine ignition agent storage and supply device mainly comprises a shell assembly, a metal film box assembly, a gas path isolation assembly and a liquid path isolation assembly. An ignition agent is strong chemical active substance, oxygen and water are required to be isolated from the environment duringstorage and use, and the rocket engine ignition agent storage and supply device realizes sealed storage of ignition agent liquid by adopting a metal shell, a metal film box, a gas path isolation diaphragm and a liquid path isolation diaphragm; in the ignition agent supply process, the metal film box serves as a management element, so that complete gas-liquid isolation is guaranteed, and the metalfilm box can be repeatedly used; the gas path isolation diaphragm and the liquid path isolation diaphragm are connected with the module shell through redundant sealing joints so that reliable sealingconnection can be realized, and the replacement is convenient; a charging and discharging valve is used for charging the ignition agent liquid and packaging positive-pressure inert gas, and a pressuresensor is used for monitoring the pressure of a gas cavity in a module to ensure a positive-pressure safe storage environment; and by means of the characteristics, safe and reliable storage of the ignition agent liquid can be achieved, and the characteristics of repeated supply and reusability are achieved.
Description
technical field [0001] The invention relates to the technical field of liquid rocket engines, in particular to a rocket engine igniter storage and supply device. Background technique [0002] For rocket engines with a combination of liquid oxygen and hydrocarbon propellants, since the propellant combination cannot spontaneously ignite, a special ignition system is required for engine ignition. Ignition starting with a self-igniting igniter has been widely proven to be a reliable, compact and efficient ignition scheme. Its main working principle is: install a special container pre-filled with igniting agent in the engine fuel pipeline system, press the pressurized gas to squeeze the igniting agent into the engine combustion chamber, the igniting agent and liquid oxygen undergo a spontaneous combustion reaction, and then organize fuel injection. Into the mixed combustion, to achieve ignition. The storage and supply module of igniter is an important part of the ignition syste...
