为解决小样机仅通过等比例放大得成品所带来的尺寸效应、迭代周期长的问题，本文以57mm直径的装药为对象设计发动机，选择采用全尺寸厚壁试验机进行前期验证；对圆孔-锥孔-翼柱进行多次迭代设计，获得高体积装药比、燃通比合格的装药结构，并提供了一种有关此种复杂装药的迭代设计方法

爱好者们早已从圆孔、端面药柱的制作，转向星形、翼柱、组合内孔等复杂装药结构的设计尝试。很多爱好者在此设计过程中都会发现，仅依靠经验估测和简易公式套用，很难准确把控复杂装药的燃面变化。

7.2运用CAD软件展开复杂装药燃面的设计，根据平行层推移特性设计装药结构。7.3设计装药具备恒面性，高体积装药比，且燃通控制优良。7.4运用硅胶模具进行推进剂芯棒。
