RU164925U1 - UNIT AMMUNITION WITH AN ARMORBAR - Google Patents

Abstract

Unitary munition with armor-piercing-projectile projectile, characterized in that the projectile, spun before firing in the breech of an artillery gun by generating an electromagnetic field, is secured as a rotor of a jet rocket motor in a sleeve using an obturator, which is a roller-bearing system that disintegrates and breaks up and escapes barrel channel smoothbore guns.

Description

The stabilization system of armor-piercing-projectile unitary ammunition using the generation of an electromagnetic field in the breech of an artillery gun

The utility model relates to the field of military equipment, in particular, to anti-tank artillery weapons.

The object of the utility model is the "artillery - ammunition" system.

The subject is the physical principles of maintaining the moments of force and inertia in an armor-piercing-subcaliber projectile.

Known systems "artillery gun - ammunition" in which the stabilization of the BPS released from the smooth barrel of the gun on the flight path is achieved through the use of aerodynamic surfaces in the tail of the projectile that create a stabilizing force when the longitudinal axis of the projectile deviates from the normal flight path. These systems have disadvantages:

additional aerodynamic surfaces increase the aerodynamic resistance of the air, which leads to a loss of BOD flight speed and increase the longitudinal section of the projectile, which leads to a decrease in its armor penetration.

Known systems "artillery gun - ammunition" in which stabilization of the projectile on the flight path is achieved by giving it advance rotation when moving along the rifled bore of the barrel. These systems have disadvantages:

a) rifling increases the friction force between the projectile and the barrel, which leads to a reduction in the initial velocity of the projectile, as a result, to a decrease in the penetration ability of the BPS and a reduction in the effective range of fire from an artillery gun;

b) increased friction in the bore contributes to accelerated wear of the artillery gun;

c) the technology of cutting helical grooves in the bore and leading belts in shells increases the cost of guns and ammunition.

Known systems "artillery gun - ammunition" in which the stabilization of the BPS released from smoothbore guns on the flight path is achieved by giving them longitudinal rotational motion due to the forces created by the oncoming air flow or due to the use of increased pressure coming from the channel of the barrel of powder gases . These systems are distinguished by relatively low speed of rotation of the BPS and a small effect of stabilization of ammunition.

Known systems "artillery gun - ammunition", with the master magnetic type. (see RF patent RU 2297592, publ. 04/20/2007). This system has disadvantages, in particular, the magnetic field energy is mainly spent on detaching the supporting ring sector from the shell of the projectile, in addition, the system is difficult to operate.

The objective of this utility model is to provide the effect of BPS hyperstabilization when firing from smoothbore guns.

The technical solution of the proposed utility model is the constructive implementation of the projectile obturator in the form of a roller bearing system, in order to ensure free rotation of the projectile in the obturator.

The technical result of the proposed utility model are:

1. Ensuring the possibility of preparing for a high-speed rotation shot in the breech of a smooth-bore gun (which is a stator of a valve jet electric motor) of an armor-piercing projectile made of magnetically soft materials (representing a rotor of an electric motor), under the influence of electromagnetic field forces.

2. Increasing the flight speed and armor penetration of the BPS by reducing its longitudinal section, as well as increasing the accuracy of firing from a smoothbore gun to the level of rifled artillery by giving the BPS a high-speed rotation.

A useful model is illustrated in FIG. 1, which shows the position of a unitary shot in the breech of the barrel in preparation for firing, where: 1 - gun barrel, 2 - ferrimagnetic projectile, 3 - obturator-bearing, 4 - stators of a valve jet electric motor, 5 - burning shell of the shot, 6 - powder charge, 7 - pan, 8 - galvanic shock bushing.

The principle of operation of the proposed "gun-shot" system.

When preparing for firing a gun, after determining the target, the gunner-operator selects the specified type of ammunition, and the shot is fed into the breech of the barrel (1). The stators of a jet jet engine (4) begin to generate a pulsed voltage of a controlled frequency by spinning a projectile (2) in a stationary obturator-bearing of the shot. Upon completion of the aiming operations, after the gunner-operator presses the “shot” button, the galvanic shock detonator (8) ignites the powder charge (6). Excessive pressure is pushed by the obturator, and through it the swirling shell from the burning capsule (5), and then from the bore (1). After the projectile leaves the barrel, the obturator collapses into parts and scatters like in existing samples of armor-piercing-sub-caliber feathered shells. Over the entire flight path, the swirling ammunition seeks to maintain the angle of departure according to the principle of a gyroscope.
