变燃速发射药的研究进展

Current situation of varible-buring rate propellant

综述了变燃速发射药的种类、性能及应用研究现状,指出发射药钝感包覆技术中表面钝感剂与包覆层的分布及迁移控制问题是该技术的关键。管状变燃速发射药由于制备工艺易于实现、能量性能较优而被广泛使用。分析了国内在变燃速发射药的种类、制备工艺及应用等方面存在的差距,并提出了建议。

The current situation about the variety,performance and the application of variable burning rate propellant are reviewed based on the kinds of the burning rate propellant.The article points out that the key of the technology of deterrent coated is the distribution and migration of surface insensitive agent and coating layer.Tubular variable burning rate propellant has been widely used for the easy preparation process and the optimum energy performance.The shortcomings in the variety and the preparation process and application of variable burning rate propellant in domestics are analyzed.The research of new variable burning rate propellant should be strengthened.
