Description
Technical Field
Penetration bomb, ground drilling bomb and armor piercing bomb, in particular to an outer ballistic tail-end bottom explosion speed-increasing penetration armor piercing bomb.
Background
The armor-piercing projectile is the most effective weapon for dealing with armor, the armor-piercing penetration effect finally depends on the speed when contacting the target, need obtain very high initial speed of transmission through the barrel artillery, but can slow down gradually because of air resistance after the warhead goes out of the chamber, the penetration armor-piercing ability when reaching the target reduces, even becomes the end of strong crossbow, and the more far away the distance hits the precision and is lower, still can lead to the artillery heavy huge for improving the warhead initial speed, reduces mobility and convenient operation.
Rocket projectiles have low precision, can be accurately sheathed by kinetic missiles, but have high cost, and can obtain enough armour penetration capability by being accelerated for a long distance (at least about one thousand meters) after being launched, and can not be sheathed at a short distance.
The recoilless gun, the antitank rocket launcher and the like are light, but have low initial speed and lower outer ballistic trajectory terminal speed, so that the penetration capability is low, and the recoilless gun is not suitable for being used as a armor-piercing weapon.
Ground-boring bombs, anti-runway rocket bombs and the like need to be accelerated by a rocket for a long distance, so that the required armor-piercing speed can be obtained.
The assumed nuclear pulse propeller generates reverse thrust through continuous nuclear explosion and can accelerate the spacecraft to the subsonic speed. Similarly, the conventional explosive generates instantaneous reverse thrust during explosion, the acceleration time and distance are very small, and the reverse thrust efficiency generated by the energy-gathered explosive explosion is higher.
The antitank rocket launcher finishes acceleration in the launching canister, but the acceleration effect is limited, about four hundred meters per second at most, and the penetration ability of the armor is not enough.
Disclosure of Invention
The invention aims to solve the problems that: the warhead is accelerated over a short distance to a speed sufficient for penetration.
The basic scheme adopted by the invention is as follows: the near-explosive fuze is arranged on a warhead, the near-explosive fuze comprises a armor-piercing bomb or a penetrating bomb, energy-gathered charge is additionally arranged at the rear part of a penetration warhead part, and then a rocket engine or a metal bomb bottom is arranged behind the warhead part, the warhead is launched or self-propelled through a cannon, even the warhead is delivered by an unmanned aerial vehicle or manually arranged, although the speed of the warhead reaching a target is low, the tapered charge at the rear part of the penetration warhead part can be detonated under the control of the fuze, energy-gathered jet flow is ejected backwards to generate instant reverse thrust, the warhead is pushed to be increased to high speed within a very short time and a very short distance, the target is penetrated, and series multi-stage energy.
First, a fuse.
The use of a proximity detonator, placed at the head of the warhead, can cause the initiation of a shaped charge behind the penetration warhead when the warhead is at a distance of about one meter from the target, with the reverse thrust accelerating the penetration warhead.
The head of the bullet can also be provided with a contact rod with a piezoelectric fuse at the front end, like a fuse with a piezoelectric transistor at the head of a nail-breaking bullet.
Second, barrel artillery shooting ammunition.
The penetration part of the ammunition is a common armor piercing bullet, a long rod armor piercing bullet and the like.
The warhead is a proximity detonator, and the warhead, the explosion-proof body and the energy-collecting charge in the cylinder are sequentially arranged behind the warhead, and the metal warhead bottom is used for resisting the pressure of the chamber.
The metal plug type bullet bottom is used for resisting the pressure of a chamber, and the back thrust effect is also increased when the tail of the tail section of the bullet bottom is exploded by energy-gathered explosive.
The warhead can be used as a mine or barrier-breaking tool without launching a medicine and placed beside a target to trigger the warhead to obtain a certain speed and penetrate the nearby target.
Thirdly, self-propelled ammunition.
The unmanned aerial vehicle is used on rocket projectiles or missiles propelled by rocket engines or low-speed unmanned aerial vehicles, so that the unmanned aerial vehicle also has high penetration capability.
The first end is a fuse, and then the penetration warhead, the explosion-proof body, the energy-gathering charge, the heat insulation plate and the solid rocket engine are sequentially arranged. When the fuse leads the shaped charge to detonate, the thermal insulation board and the rocket motor are directly washed away.
And fourthly, throwing ammunition.
The method is mainly used for guided bombs or unguarded bombs. The head part is a near-explosion fuse or the long rod fuse, and then the penetration warhead part, the explosion isolation plate, the energy-gathering charge and the metal bullet bottom or the cylinder-packed tungsten steel sand are sequentially arranged, so that the back thrust generated by the energy-gathering charge explosion is larger.
When the guided or unguided throwing ammunition falls to a certain height away from a ground target, the fuze detonates the energy-gathered charge to push the penetration warhead to accelerate penetration or ground drilling.
And fifthly, layout type.
The structure of the device is the same as that of the throwing ammunition, but the tail wing is not arranged, and the device is arranged on a bracket and a direction finder and is arranged beside a target.
Sixthly, serially connecting multi-stage shaped charges.
Two-stage or multi-stage series shaped charges can be adopted, and the explosion-proof layer is arranged in the middle of different stages of shaped charges. In order to prevent deviation, a guide rail or a cylindrical director is arranged, an electronic fuse is used for controlling, the detonation is started from the rearmost energy-gathered charge, more than two times of explosions are accelerated, the interval is extremely short, and more than two times of instantaneous acceleration are obtained at the penetration warhead. This is mainly suitable for lining-type ammunition.
Seventhly, the tail section of the rocket tube is accelerated.
If the requirement on the penetration capability of the warhead is not high, the detonation acceleration at the tail section can be adopted. The near-explosion fuse is arranged in front of the penetration warhead, the fast-burning rocket engine for the anti-tank rocket tube is arranged behind the penetration warhead, and when the warhead reaches the position close to the target through a rocket or a low-speed artillery, an unmanned aerial vehicle or a throwing bomb, the explosion fuse enables the rocket engine to deflagrate to generate instant reverse thrust, so that the penetration warhead is accelerated to the target within about one meter, and the speed of penetrating through the thin armor is achieved.
And eighthly, beneficial effects.
The low-speed artillery, the recoilless artillery, the rocket artillery and even the artillery thrown by the unmanned aerial vehicle can obtain high speed instantly when the lower speed is close to a target, so that a better penetration and armor piercing effect is realized. Even high-speed armor piercing bullets, the ground-boring bullet can be suddenly accelerated at the tail section of the trajectory, and faster speed and armor piercing effects can be achieved. Statically arranged ammunition can also achieve high speeds over short distances.
For rocket guns or rockets-propelled missiles, the time and distance required for acceleration after launching can be reduced, the precision is improved, the flexibility is enhanced, and the guidance cost is reduced. The detonation speed is increased when the target is reached, and the precision of the whole outer trajectory is not influenced.
The energy-gathered charge explodes outside the target, and the damage effect outside the target can be realized, while the damage effect of the traditional armor piercing bullet on the outside of the target is smaller.
