将前期损毁的火箭再生后做发动机测试之用.说明如下: 1.全箭质量:76g(含发动机) 箭长:420mm 箭体直径:24mm 弹头和箭体材料:纸张(挂历报纸) 尾翼材料:铁皮(罐头盒

我的那个火箭是两级上升式的，液推部分一分级（箭体纵向固定），固推一级，尾翼安在液推部分外壁上，所以可以排除尾翼故障，主要是在固推这出问题了，团队最后诊断为，在设计外螺纹模式下的拉瓦口及整个燃烧室时，须在气动平衡上下大功夫

引用 1160599678:我记起了之前别人厂商的一个办法，我以前参加三模比赛，比的是火箭组装（固体火箭），然后它开伞的方式也很粗暴，就是箭体和头锥用绳子连接起来，然后在头锥上绑一个伞塞进箭体里，用滑石粉保证润滑
