Description

High-efficiency damaged energy-collecting charge supercavity projectile warhead

Technical Field

The invention relates to the field of underwater supercavitation ammunition, in particular to an underwater supercavitation projectile warhead for efficient damage.

Background

The weapon in water becomes an indispensable part in sea warfare, and the density of air and water is different by a plurality of orders of magnitude, so that the movement conditions of the projectile in water and air are quite different, and the movement resistance of the projectile in water is far greater than that in air. Therefore, underwater range-increasing drag reduction becomes an important field for researching underwater weapons, and the underwater supercavity technology becomes a main breakthrough for solving the problem. The damage mechanism of the traditional underwater supercavity projectile mainly depends on the self kinetic energy, and the kinetic energy projectile needs to have the minimum speed capable of damaging a target at the endpoint so as to achieve the purpose of damage.

For a traditional supercavitation projectile, the navigation speed of the projectile needs to be properly controlled before the projectile reaches a target so as to meet the speed requirement of terminal damage. This is difficult to achieve with conventional uncontrolled kinetic energy projectiles, and requires high initial velocity for launch and strength of the projectile when it enters water. The increase of the uncontrolled kinetic projectile range inevitably leads to the reduction of the speed near the end point, so the initial launching speed must be increased to ensure good damage performance under the large range, which is very harsh for the launching device of the large-range underwater supercavity projectile, therefore, the two are contradictory in the problems of range extension and high-efficiency damage, and the prior art does not solve the contradiction.

Disclosure of Invention

The invention provides a super-cavitation projectile warhead with good damage performance and large range, which can separately consider two factors of damage and range, and the kinetic energy of the projectile only needs to be ensured to collide with a target, does not require collision speed, and the damage can be completely borne by energy-gathered jet generated after a fuse is triggered by collision. The invention simultaneously applies the supercavity drag reduction technology and the energy-gathering charge technology, increases the shooting range of the projectile and enhances the damage capability of the projectile.

The technical solution for realizing the invention is as follows: a high-efficiency damaged energy-collecting charge supercavity projectile warhead consists of five parts, namely a detonator 01, a charging cylinder 02, a V-shaped liner 03, an energy-collecting charge supercavity projectile head 05 and a cavitator 06;

the opening end of the head 05 of the energy-gathered charge supercavity bullet is connected with the opening end of a charge cylinder 02 provided with a V-shaped charge cover 03 through threads, and a cavitator 06 and the head 05 of the energy-gathered charge supercavity bullet are of an integral structure; the detonator 01 is inserted into the other end of the cartridge 02.

Compared with the prior art, the invention has the following remarkable advantages: 1) the invention solves the problem of the conflict between the voyage and the damage performance of the uncontrolled kinetic energy supercavitation projectile 2) the invention improves the damage mode of the kinetic energy supercavitation projectile and can efficiently damage the target underwater on the premise of ensuring that the energy-gathered jet with good damage capability can be formed. 3) The invention has simple structure, can change the sizes of the liner and the cavitator with different included angles in the liner and the cavitator in a short time, and simultaneously adjusts the explosive height, thereby improving the head size and being convenient and fast to process.
