Abstract

A projectile of the type to be stabilized by rotation is formed with an asymmetrical point. In one embodiment a pair of unequal, diametrically opposed recesses are provided and apportioned so that the center of gravity of the projectile is located along the projectile'"'"'s axis of rotation.

Claims

1. A small-caliber projectile with an asymmetrical tip, of the type stabilized by rotation, and whose tip is provided with an asymmetry which exerts its effects upon penetration of the projectile in a target, characterized that in the tip of the projectile there are two diametrically located recesses which are unequal with respect to each other, said recesses having the effect of increasing the rate of spin of the projectile during its penetration into a target.

2. A small-caliber projectile with an asymmetrical tip as set forth in claim 1, characterized in that the angles formed by the two recesses with the axis of the projectile are distinct with respect to each other, and in addition are advantageously less than 30°

, in order to originate little air drag.

3. A small-caliber projectile with an asymmetrical tip as set forth in claim 2, characterized in that the tip of the projectile is formed by the two recesses, and is eccentric with relation to the axis thereof, due to the differences existing between said recesses;

this eccentricity being related to said diametrical recesses in such a way that the projectile'"'"'s center of gravity is located on the rotational axis thereof.

4. A small-caliber projectile with an asymmetrical tip as set forth in claim 3 characterized in that the tip is formed in the manner of an ogive and said recesses are disposed in the ogive and are formed by flat surfaces, according to the rotational torque required.

5. A small-caliber projectile with an asymmetrical tip as set forth in claim 3 characterized in that the tip is formed in the manner of an ogive and said recesses are disposed in the ogive and are formed by curved surfaces, according to the rotational torque required.
