| 摘 要： | 普通弹丸的底阻约占弹丸总阻的１／３。因此，准确测量底阻是准确测定弹丸总阻的关键。在超音速风洞中进行测力实验时，模型底部大多用一根天平支杆将模型支撑在风洞中。由于支杆的存在，模型底部大多用一根天平支杆将模型支撑在风洞中。由于尾支杆的存在，使得模型底部流动发生畸变，引起底阻测量的不准确。本介绍了天平尾支杆和模型船尾角对超音速弹丸底压测量的影响。研究表明，尾支杆直径从小到大变化时，底压经历了一个由大到

| Abstract: | Presents the effect of tail sting and the angle of boat tail on the base pressure of a projectile in flight at supersonic velocities. The base pressure goes through a process of reduction and then an increase when the relative diameter of the sting changes from 0 to 1. The angle of boat tail tends to increase the base pressure when the angle of boat tail is within the critical angle of separation. |
