摘要
利用火炮身管等齐膛线的缠角α值沿炮膛轴线始终为一个常数的原理,在炮膛纵向展开的平面图中,利用直角三角函数换算关系,提出了等齐膛线缠角的简易检测方法,比较简便实用。
This text is according to the principle that gun barrel twist angle ＂α＂ is a constant and use Rt△ trigonometric function relation on the developed view of the tube bore. A easy method of checking twist angle of uniform twist rifling was presented and had been applied.
