Abstract

The invention relates to an internal heating nitrous oxide monopropellant gas generator. A high-temperature decomposition product of nitrous oxide gas can be applied by utilizing the characteristics of nontoxicity, non-pollution, high decomposition temperature and self-sustaining decomposition reaction of the nitrous oxide gas. The internal heating nitrous oxide monopropellant gas generator can be taken as a monopropellant thruster to be applied to the attitude control of satellites, and also can be taken as an oxidant source and an ignition device to be applied to the oxidant supply and ignition of a small liquid-propellant rocket engine or a solid-liquid rocket engine. Compared with the internal heating nitrous oxide monopropellant gas generator adopting the conventional external heating preheating mode, the internal heating nitrous oxide monopropellant gas generator adopting the unique heating mode and overall layout can effectively improve heating efficiency, save energy and ensure relatively long service life.

Description

【Technical field】

[0001] The invention relates to a small-sized internally heated nitrous oxide single-unit gas generator. The device uses nitrous oxide gas as a working medium, and can be used as a single-unit thruster for attitude control of satellites, and can also be used as an oxidant source And the ignition device is applied to the oxidant supply and ignition of small liquid rocket motor or solid-liquid rocket motor. 【Background technique】

[0002] In order to break through the many limitations of traditional micro-propulsion systems in terms of safety and performance, the use of nitrous oxide as a monopropellant has become one of the development directions for the development of non-toxic propellants. Nitrous oxide is non-toxic, non-corrosive, and has good stability at room temperature; and its saturated vapor pressure is high (about 50 atm), and it can be self-pressurized to realize propellant extrusion transportation; when it is used as liquefied gas for propulsion,...
