The air drag coefficients of spherical tungsten fragments are studied. The fragment includes ideal sphere and real fragment formed by a warhead. The experimental results show that: (1) for ideal spheres, the attenuation coefficient of velocity is constant, the air drag coefficient is slightly affected by the initial velocity and is a linear function of initial velocity, and (2) for real fragments formed by a warhead, the flight performances are different from ideal spheres, the air drag coefficient is affected by the flight velocity and is a linear function of flight velocity.

实验研究了理想球形钨合金破片和经历爆轰驱动的球形钨合金破片长距离飞行时的速度衰减规律。实验结果表明:(1)对于理想球形钨合金破片,在同一初始速度条件下,衰减系数为常数,空气阻力系数与初始速度有关,两者成线性关系;(2)对于经历爆轰驱动的球形钨合金破片,由于有轻微的质量损失和变形,速度衰减规律与理想球形钨合金破片有明显的区别,空气阻力系数与飞行速度有关,两者成线性关系。

实验研究了理想球形钨合金破片和经历爆轰驱动的球形钨合金破片长距离飞行时的速度衰减规律。实验结果表明:(1)对于理想球形钨合金破片,在同一初始速度条件下,衰减系数为常数,空气阻力系数与初始速度有关,两者成线性关系;(2)对于经历爆轰驱动的球形钨合金破片,由于有轻微的质量损失和变形,速度衰减规律与理想球形钨合金破片有明显的区别,空气阻力系数与飞行速度有关,两者成线性关系。

The air drag coefficients of spherical tungsten fragments are studied. The fragment includes ideal sphere and real fragment formed by a warhead. The experimental results show that: (1) for ideal spheres, the attenuation coefficient of velocity is constant, the air drag coefficient is slightly affected by the initial velocity and is a linear function of initial velocity, and (2) for real fragments formed by a warhead, the flight performances are different from ideal spheres, the air drag coefficient is affected by the flight velocity and is a linear function of flight velocity.
