固体发动机装药CAD

基于计算机图形处理直接获得燃面几何数据,发展了一种装药设计新方法,可以进行装药燃面、质量及惯性随肉厚变化的计算,为一维内弹道计算及流场计算提供更为详尽的数据,还能进行动态燃面推移,使设计者直观地判断其设计的合理性。

Computer Aided Design of Propellant Grains for Solid Rocket Motors

A new Propellant grain design method which is based on computer graphic Processing techniques by geting burning suface data directly is developed .On this basis, other data such as burning area, mass properties and inertia properties versus web can be caculated respectively. Moreover,more detailed data for one dimensional internal ballistic and internal flow field caculations are presented. A propellant grain design computer code was developed. A dynamic burning surface recession allows the user to judge if his design is reasonable.
