提高小口径杆型弹飞行稳定性的弹体设计方法探讨

The Discussion of Design Method about Improving Small Caliber Long Rod Bullet's Flying Stability

论述了一种改进杆型弹飞行姿态的方法 ,并根据简化受力模型 ,分析了弹丸的受力情况 ,比较了改进前和改进后三种弹飞行姿态的优劣 ,试验证明质心和阻心确实是影响飞行姿态的一个重要因素 ,通过正确的调整可以大大地改善飞行姿态 ,提高飞行稳定性。

An improvement method of long rod bullet's flying pose is expatiated, also ,theoretic model is built and the different flying pose of three kinds of bullets is compared. Tests imply that center of mass and resistance center are the important influence factors of flying pose, and properly adjusting the position of center of mass and resistance center can improve the flying pose and stability.
