Description

The utility model relates to the field of military equipment, in particular, to armored weapons.

The object of the utility model is “a system of smooth-bore artillery with a capsule for armor-piercing sub-caliber projectile - liquid propellant loaded into the capsule before firing - electromagnetic field generator”.

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

Known stabilization systems of shells, representing the system of "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 paths. 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 stabilization systems 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.

The objective of this utility model is to increase the speed of the projectile, range and accuracy, as well as the power of the BPS when meeting with an armored obstacle due to the use of the effect of hyperstabilization when firing from smoothbore guns.

Technical solutions of the proposed utility model are:

1. The statement in the breech of the smooth-bore guns of the electromagnetic field generators, which are a stator of a valve jet electric motor. BPS, made of soft magnetic materials, in preparation for the shot, playing the role of a rotor or engine armature, tends to settle down along the field and twists to the required significant value (6-10 thousand rpm / sec) with voltage pulses of controlled frequency. Achieving high rotation speeds should minimize deviations of the projectile position from the angle of departure, not only on the flight path, but also when meeting with an armored obstacle.

2. The placement of the projectile in a sealed, dielectric capsule, which is a cell of the drum in the breech of the artillery gun.

3. Filling this capsule with a liquid propellant charge in preparation for the shot. The liquid medium should help minimize the frictional force arising from the rotation of the projectile.

4. Giving the projectile without aerodynamic stabilizers a special shape that allows the projectile to rotate freely in the shutter and the shutter to slide off the flying projectile immediately after loss of acceleration.

The technical result of the proposed utility model is the ability to stabilize the projectile by rotating before the shot, which will eliminate the use of aerodynamic stabilizers, reduce the projectile cross-section, increase the projectile flight speed, range and accuracy, as well as the power of the BPS when meeting with an armored obstacle.

A useful model is illustrated in FIG. 1, which shows the position of the projectile in the capsule of the drum in preparation for firing, where: 1 - the gun’s barrel, 2 - the ferromagnetic projectile, 3 - the shutter, 4 - the stators of the valve jet electric motor, 5 - the burning shell of the shot, 6 - the liquid propellant, 7 - valve system for supplying liquid propellant charge.

The principle of operation of the proposed "stabilization system armor-piercing projectile with liquid propellant charge using the generation of an electromagnetic field."

When preparing for firing a gun, after determining the target for a hit, the gunner-operator selects the specified type of ammunition and the drum with the specified type of shot is rotated by positioning the shot in the axis of the barrel (1). A liquid propellant charge is poured into the shot capsule through the valve (7). The stators of a valve jet engine (4) begin to generate a pulsed voltage of a controlled frequency, twisting and stabilizing the projectile (2) along the electromagnetic field. Upon completion of the aiming operations by pressing the “shot” button, the gunner-operator switches the generator frequency to hyper-revolutions. Upon reaching a certain frequency, the centrifugal force creates a critical pressure in the capsule with a liquid propellant charge (6), causing the detonation of the explosive mixture. Excessive pressure pushes the obturator, and through it the swirling projectile from the burning capsule, and then from the bore. The liquid mixture displaced by the projectile in front of the obturator reduces the friction force of the obturator against the bore, and after passing through the projectile it immediately detonates, causing an additional increase in speed. After the projectile with the obturator takes off from the bore, the pressure of the powder gases directed to the rear area of the obturator forces it to move with acceleration until this force is overpowered by the air resistance force. From this moment, the obturator ceases to put pressure on the projectile, and therefore, the projectile having less resistance begins to overtake the obturator, slipping out of it. Over the entire flight path, the swirling ammunition seeks to maintain the angle of departure according to the principle of a gyroscope. When the BPS encounters an armored obstacle, a significant moment of inertia of the projectile is an additional factor counteracting the rebound.
