基于一维气相稳态反应流的燃速预估软件研究

Study on Software of Solid Propellant Burning Rate Prediction Based on one-dimensional Steady-state Reaction Gas Flow

在一维气相稳态反应流模型的基础上,总结了适用于双基推进剂、改性双基推进剂、复合固体推进剂燃速预估的修正因子,拓宽了燃烧理论模型的适用范围。采用Visual C++和Microsoft Access为开发工具,完成了基于组分化学键结构参数的固体推进剂燃速预估软件(SPRS)编制。该软件基于Windows XP系统,界面友好,使用方便,具有数据更新和信息查询功能。用户不仅能根据推进剂的化学组成(配方)和给定压强计算燃速、压力指数等参数,还可根据给定的燃速和压力指数等调整推进剂配方组成,对缩短固体推进剂研制周期和节约研制成本具有重要意义。

Based on the model of one-dimensional steady-state reaction gas flow, the correction factors of burning rate related to double base propellant, modified double base propellant and composite solid propellant were summed up, the application scope of theoretical combustion model was broadened. Using Visual C ＋＋ and Microsoft Access for the development tools, the software of solid propellant burning rate prediction（SPRS） was completed by the structural parameters of chemical bonds. The software was based on system of Windows XP, user-friendly, easy to use ,and with the functions of data updating and information querying. The burning rates and pressure indexs could been calculated when the chemical compositions of the propellant （formula） and the pressures were given. The compositions of the propellant（formula） could be adjusted by giving the burning rates and pressure indexs too. It was of great significance in development of cycle-shortening and cost-saving of solid propellant.
