Spin or aerodynamically stabilized ammunition

摘要

Disclosed is spin-stabilized ammunition for use in grooved or smooth bore handheld firearms with calibers up to 60 mm. The projectile of the ammunition features a body in the shape of a truncated cone at the top of a cylinder with proportions of the cone length to the cylinder length varying between from one-to-six to one-to-three depending on the expected initial speed of the projectile after the ammunition has been discharged. A central longitudinal barrel extends through the projectile with a proportion of the entrance diameter and exit diameter of 1.38-to-one for expected discharge speeds near sound velocity or of 1.22-to-one for expected discharge of hypersonic velocities. Finally, nozzles within the projectile create a spinning motion around the projectile's axis, the nozzles being located between cavities for propellant charges.

主权项

1. A projectile that is aerodynamically stabilized, wherein the projectile comprises:
a truncated cone atop a cylinder so that the cone and cylinder share an axis; a barrel through the cone and cylinder, said barrel (a) centrally positioned through the shared axis of the cone and cylinder and (b) featuring a first end with a first diameter and a second end with a second diameter wherein the diameter at the first end is greater than the diameter at the second end; a first chamber for a first explosive charge, said chamber defined within the cone between an outer wall of the cone and the barrel; a second chamber for a second explosive charge, said second chamber defined within the cylinder between an outer wall of the cylinder and the barrel; and a nozzle that is located at the top of the cylinder between the outer wall of the cylinder and the barrel, said nozzle for providing fluid communication between the first and second chambers, said nozzle configured to enact rotation of the projectile around the axis whenever said first explosive charge is discharged.
