一种新型高燃速推进剂的燃烧性能

Burning Properties of a New Kind of High-burning Rate Propellant

介绍了一种新型推进剂的多孔结构和燃烧性能,并重点讨论了在发动机中不同装填参数下所产生的平行层燃烧。选择不同燃烧类型,可获得不同压力下的燃速及其他参数,为该推进剂的应用打下了良好的基础。

This article introduces the porons grain structure and combustion characteristics of a novel high burning-rate propellant.Base on motor test results, it is found that the propellant exhibit three type of combustion manners at different motor loading parameters. The combustion manners include parallel layer burning, limited convection burning and convection burning.
