Abstract

The invention discloses an aluminum-rich fuel electric ignition solid propellant and a preparation method thereof. The solid propellant is composed of hydroxylamine nitrate, an oxidizing agent with cosolvency, polyvinyl alcohol, aluminum powder, other metal powder and additives. The raw materials are mixed in a reactor according to determined ratios, fully stirred at room temperature under vacuum conditions and then cured and molded under a constant-temperature condition. The solid propellant has the characteristic of electric ignition, the preparation method is simple and easy to operate, the safety factor is high and the solid propellant is environmentally friendly.

Description

technical field [0001] The invention relates to the field of solid propellants, in particular to an aluminum-containing fuel-rich electric ignition solid propellant and a preparation method thereof. Background technique [0002] In modern propellant systems, high stability, high performance and high flexibility and controllability are the main development directions. There are two main types of propulsion systems: liquid propulsion and solid propulsion. [0003] Although the technology of the liquid propulsion system is more mature than that of the solid propellant system, it has better controllable performance of ignition and flameout, but its structural system is relatively complicated, and there are many moving parts similar to valves, so it is necessary to design a high-stability and high-precision operation system, resulting in higher costs. [0004] In addition, the liquid propellant used in the liquid propulsion system has certain toxicity and is more harmful to the...
