Definitions
- the present invention relates to a shell and bullet or shell or other ballistic projectile device allowing greater ballistic precision resulting from an improved air penetration and an increase in speed and consequently in the momentum of the ball .
- the bullets existing at present have a profile whose aerodynamics rests on the outer lines of the projectiles. As a result, opposition to air resistance increases with the surface and volume of the projectile.
- the device according to the invention makes it possible to escape this principle.
- a bullet in fact comprises a bullet pierced in its center from the base to the top and a socket comprising an integral metal axis which fills the opening of the bullet;
- This metal axis which is a function of the bullet hole allows the explosion to unfold under the conditions of a conventional bullet because it prevents the loss of pressure during the explosion which could be due to a leak by drilling the ball.
- the ball thus propelled offers only a low resistance to air because of the hole passing right through.
- the length of the axis, its diameter and metal which composes it can be adapted to the various constraints of friction type etc ... imposed by the conditions of shooting of the various projectiles.
- the length of the bale and its piercing can be modified according to ballistic tests.
- FIGURE 1 shows in section, the device according to the invention.
- FIGURE 2 shows in section in the plane perpendicular to that of Figure 1 the same device. This figure is identical to Figure 1 because the device has a symmetry of revolution.
- the device comprises a socket (1) provided with a metal shaft (2) of variable length, the fasteners (3) of which allow the combustion of the powder (4) triggered by the primer ( 5) for the propulsion of the pierced bullet (6).
- the metal axis (2) allows the hole in the bullet (6) to be closed so that the explosion takes place under satisfactory conditions.
- the device according to the invention is particularly intended for improving the performance of ballistic projectiles.
