摘要: 首次利用正交试验优化设计方法对固体发动机三维药柱进行了优化设计。计算的结果表明这种方法非常有效。在优化模型中,对药柱的燃面计算采用了通用坐标法。这种处理方法使本文的优化设计更为通用。

Abstract: Orthogonal test method is applied to design optimization of 3D grains of solid motors.It is proved that this method is very effective according to the calculation result. In the optimizationmodel, we choose "general coordinate" method to compute burning area of grain which makes thisoptimization method universal.
