摘要
弹丸的气动外形对其外弹道性能有重要的影响。减小飞行阻力对缩短弹丸飞行时间、增加射程、减小飞行速度衰减都是有利的。本文针对目前低阻增程弹的情况,导出了最小波阻母线方程,对低阻增程弹的气动外形设计有一定参考意义。
The aerodynamic shape of projectiles strongly influences their performance on ballistic trajectory. Reduction of drag is very helpful in shortening the flight time and increasifig the range or to slow down the reduction in velocity. According to the present status of the extended range projectiles, the paper is devoted to a study of their aerodynamic shape and deduces contour equations leading to smallest wave drag. It is useful in the design of aerodynamic shapes for such a kind of projectiles.
