Abstract

The invention discloses a liquid-solid mixed propellant and a charging method thereof. The liquid-solid mixed propellant is prepared from 88%-95% by weight of a standard solid propellant and 5%-12% byweight of an aqueous hydroxylamine nitrate solution, and the mass concentration of the aqueous hydroxylamine nitrate solution is not lower than 80%. The charging method is simple and easy; by means of a unit prepared with the liquid-solid mixed charging method, slow-burning release of hydroxylamine nitrate can be realized, burning gas of the standard propellant is sufficiently burnt again, content of CO gas in fuel gas is reduced, and environment-friendly burning and regular control for energy release are realized.

Description

technical field [0001] The invention relates to the field of weapon preparation, in particular to a liquid-solid mixed propellant and a charging method thereof. Background technique [0002] The main requirements of barrel weapons for solid propellants are high energy and controllable combustion law, that is, to increase the utilization rate of energy, so as to achieve the purpose of increasing the muzzle velocity of the chamber pellet under a certain chamber pressure. Today, higher requirements are put forward for the combustion of propellants, and the combustion is clean and green, that is, to minimize the content of harmful gases (mainly CO) in the combustion gas. In order to meet the needs of green combustion and launch of weapons, high-energy new materials directly filled with oxygen-enriched materials such as ammonium nitrate (NH 4 NO 3 ), ammonium perchlorate (NH 4 ClO 4 ), potassium perchlorate (KClO 4 ) etc. improve the oxygen balance and energy of the propella...
