Abstract

Bullet without bushing, characterized by the fact that it has in the culotte, "the flange" properly biased thanks to grooves and/or grooves that allows the folding of the same, as a result of the explosion up to a diameter similar to the diameter described by the initiator or multiplier, which may be semimaciza and/or hollow core, depending on the benefits you want to obtain. Likewise, the tip of the bullet without cap, is reserved for the multiple functions of the bullet, tracer, breaker, explosive, expansive, etc. The area where the holes are housed should be kept in the position described in the explanatory drawings, once the explosion occurred, as well as the areas that exist from the contact with the bore of the barrel, to the tip of the bullet.

Description

Bullet without cap.

The present invention relates to a bullet that unlike the bullets known so far, you don't need cap or sheath, and that thanks to its design, features and operation, avoids the expulsion process that all weapons perform with respect to the cap once the Shooting. And whose main advantages are cost elimination cap or sheath manufacturing, smaller bullet size, and faster firing, since the ejection phase of the bushing does not there is, in addition, avoids the encasquillamiento of the arms. Supposed also a lower weight and an ammo storage capacity greater than hitherto known.

In addition and to reduce the size of the bullet without bushing is planned to use an explosive of the type compact and agglomerated nitro cellulose powder.

Background of the invention

Various types of similar bullets are known, but in reality the only thing they have achieved is to reduce the size of the cap, or replace it with a powder coated block by varnishes, lacquers or the like, as in the case of ammunition used by the German assault rifle HK G 11. But this bullet It presents a great inconvenience, since the projection load It is covered by varnishes, lacquers or similar, it originates easily and spontaneously an auto explosion of the charge of projection, initiator, etc. Originated by the logical warming of the gun barrel, in addition to shutting the gun barrel.

Description of the invention

The bullet without cap or sheath object of this patent, consists of a unique piece that will serve as a receptacle of the initiator and / or multiplier load, as of the load of projection, likewise will be the projectile that hits the target Or aim to beat.

Two different models have been devised as far as to its design, and according to the benefits that you want to achieve. He First bullet concept without a bushing, it will be closed or semi-solid, while the second model has been designed with a soul hollow

In the first bullet model without a cap, closed or semi-solid, its operation will be as follows. One time that the firing pin of the weapon has impacted on the initiator or bullet multiplier 9, which is housed in the shorts 10, this initial explosion will be transmitted to the entire load of propulsion or projection 4. In order for the entire bullet to slide through the barrel of the gun 2, the culot of the bullet without a cap 10, and more specifically tab 7, will be provided with slots and / or grooves 8. These grooves and / or grooves must be the strong enough for the bullet without a socket be fixed before launch. And in turn, they must be sufficiently flexible, semi rigid and / or elastic, so that Once the explosion occurs, fold back with regarding the direction of the bullet, allowing, in addition to the free displacement of the bullet without a cap through the gun barrel, and obtaining an aerodynamic shape of the entire bullet in its set, thus facilitating its penetration into the air, avoid turbulence etc. Zone 3 will be the outer wall of the bullet without cap that will be in contact with the gun barrel, which together with stretch marks and attached to the aerodynamic shape of the Bullet without socket, will facilitate the movement of said bullet through the air until it reaches its goal.

Zone 1 will be the tip of the bullet without cap and will be intended for the various applications that you can have the bullet, such as expansion, explosion, incendiary, plotter, perforator, etc.

In the second bullet model without a socket, or hollow bore, the operation will be similar to that of the first mentioned previously, with the sole exception that zone 11, or anima of the bullet without a cap will be full of explosive or not, depending on the benefits you wish to obtain, but in any case, this bore will remain hollow once the explosion of The projection load. Points 5 are pores, perforations that facilitate the correct detonation of both the explosive located in zone 4, as in zone 11, transmitting this detonation of inside to outside and / or vice versa. And also in this bullet model without socket with hollow bore, it will be taken into account that both the tip of the bullet zone 1, as the initiator and / or multiplier zone 9, will remain completely open after detonation, to the object to allow the free circulation of air through the bore zone eleven.

In both cases of bullet without bushing, that is, in the closed or semi-solid model, and in the hollow bore model, the material used for the construction of the same, will be the most convenient, depending on the needs to be covered, such as for example, kinetic energy, penetration force, initial velocity, range, etc. Using the usual formulas. The explosive used will be of the compact powder cellulose nitro powder type and / or aglo-

Description of a preferred embodiment

Once the bullet without a socket has been located in the position suitable for firing, the firing pin of the weapon will impact on the initiator and / or multiplier 9. Act followed and by action of the multiplier and / or initiator, this explosion to the entire projection load 4, responsible for propelling The bullet without a cap. Then the bullet without a socket can be slide freely along the gun barrel thanks to the fact that slots and / or grooves 8, located in tab 7, have been folded backwards, adopting the gun barrel once abandoned, a posture or aerodynamic position to avoid any type of turbulence or similar.

In the case of the bullet without a bushing with a bore hollow, the operation will be similar, with the particularity that the bore zone 11, depending on whether or not it is full of projection, will explode from the inside out or vice versa, thanks to the pores and / or perforations 5, and in any case both zone 1, as the initiator and / or multiplier 9, they will be completely perforated in order to ensure the free circulation of air, facilitating, thus, a greater capacity of penetration in the air, scope, etc.
