ABSTRACT:
A projectile that is primarily suited for supersonic flight, such as a bullet, a shell, or a rocket, incorporates the model of the natural wave behavior. The leading edge of the projectile has a sharp tip which merges smoothly into a cylindrical body. The merging segment from the tip to the cylinder may be defined with a tangent function. The rounding of the surfaces promote proper fluid sheet formation along the surface and to reduce undesirable vortice formation and thus to reduce the value of several drag factors.
