本文从理论上对低速杆式弹的气动特性做了初步分析与探讨;重点闸述了杆式头部弹丸对减少头部法向力、增加阻力从而对提高弹丸稳定性的好处;提出了在亚音速范围内低速杆式弹的气动力系统的估算公式,并列举了部分实验数据及图表,将估算值与实验值加以对比,二者基本相符.
In this paper, the aerodynamic characteristics of low-speed rod-type projectiles are theoretically analyzed and discussed. The advantages of the projectile-type projectile on decreasing the normal force of the head and increasing the resistance of the projectile are emphasized. The calculation formula of the aerodynamic system of low-speed rod-type projectile in the subsonic range is also given. Some experimental data and charts are listed. The estimated values are compared with the experimental values, and the two are basically in line with each other.
