Title Application to multi-stage particle size distribution in solid propellant
Abstract
Solid propellant is a kind of composite materials with specific function and power source of missiles, space vehicles of various types of solid rocket motor. In this article, by analyzing the technological development of modern solid propellant, summarized the development of solid propellant technology, the development course of a solid propellant technology has been generalized.
By introducing new energy solid propellant progress and combined with the development status of foreign solid propellant, some problems about propellant performance and technical features has been expressed ,it analyzed the gap of the solid propellant between at home and abroad . By analyzing the distribution of dense arrangement of solid propellant grains, a multi-level particle size distribution in the solid propellant about the deployment of the application has been put forward, also it proposed a proposal about solid grains fill solid propellant and completed grading proposal in a single size gradation programs and two dimensions particle size gradation programs by using the program named Visual Basic, so the density of the propellant will be highly enough to let the propellant obtain a higher energy.
Keywords Solid propellant high-energy multi-level particles high-density composite propellant energetic materials
