A kind of electric control solid propellant and preparation method thereof

Abstract

The invention relates to an electronically controlled solid propellant and a preparation method thereof, belonging to the field of solid propellants. The electronically controlled solid propellant includes the following raw materials in mass percent: 10% to 14% of a hydroxyl-containing binder, 80% to 85% of a main oxidant, 1% to 4% of a secondary oxidant, and 0.5% to 0.5% of a crosslinking agent 2%, functional additive 1% to 2.5%; wherein, the main oxidant is an aqueous solution of hydroxylamine nitrate with a mass concentration of 5% to 10%, and the crosslinking agent is one of a silicon-containing compound or an organic titanium chelate or a combination. The invention can avoid a lot of gel groups and air bubbles in the slurry, and significantly improve the uniformity of the electronically controlled solid propellant.

Description

technical field

[0001] The invention belongs to the technical field of solid propellants, and relates to an electrically controlled solid propellant and a preparation method thereof. Background technique

[0002] Solid rocket motors have the advantages of simple structure, fast response, and convenient use and maintenance. Therefore, they are widely used in strategic and tactical missile weapons. However, once the solid propellant is started, it cannot be extinguished, so that the solid rocket motor cannot be started multiple times, and it does not have flexible energy management capabilities, which seriously restricts the wide application of solid propulsion technology. The liquid rocket engine has the characteristics of multiple starts and precise thrust adjustment, but the structure of the liquid engine is complex, and most of the liquid propellant components are highly toxic, flammable, explosive, volatile and corrosive, and the storage period is limited. In the use env...
