的常压燃速没怎么高啊......如果真的这么高你的失败就很容易解释了....我的KNSU确实是这样的，11CM的烧了8秒，可能是由于测燃速的时候点的面积大了，不过总体上来说还是优秀的KNSU，性能很变态，只要有好的喷口

弹头夹是通过这个收缩的方式夹紧电机轴的，只不过不是抛物线，是一个收缩的锥形理论上说没有压缩段就不能跨音速喷气，且扩张段角度非常窄，我认为该部件产生马赫环的原理与拉瓦尔喷口存在较大差异。

发动机的超音速气流和嘴吹的亚音速气流性质不一样拉瓦尔喷口只有工作在设计的压强比下才能达到设计的性能引用楼主qw2582于2010-08-07 16:21发表的拉瓦尔喷口、 :我用堵漏王和自制模具
