Description
Technical Field
The invention relates to the technical field of detonation physics, armor piercing mechanics and ammunition engineering, in particular to an enhanced aftereffect spinning EFP warhead.
Background
The shaped charge warhead is developed based on one-end cavity charge, and when a metal lining (namely a charge type cover) is attached to the surface of a charge cavity, after explosive charge is initiated, high-speed metal Jet flow (Jet) or rod Jet flow (JPC) or explosion-shaped Projectile (EFP) damage elements can be generated according to the shaped charge effect of different charge structures. Among them, EFP is widely used in intelligent ammunition systems, such as dead-sensitive ammunition, intelligent mines, etc., because it is not sensitive to large explosives and has strong aftereffect damage power to targets behind targets. As an application technology with a strong military application background, EFP warheads have since been developed, and long-range flight stability and end-point effects have received significant attention from those skilled in the ammunition art. Practice proves that in the EFP design process, the requirements on aerodynamic force and penetration power are on the same level (namely, when the requirement on penetration power is high, the requirement on aerodynamic force is also high, and when the requirement on penetration power is low, the requirement on aerodynamic force is also low).
In the prior art, although the quasi-spherical EFP has no flight stability problem, the penetration depth is too small to pose a fatal threat to thick armored targets and is gradually replaced by the rod-type EFP, but the serious flight stability problem is also brought. In order to improve the aerodynamic characteristics of the rod-type EFP, a tail skirt EFP, a straight tail EFP, and a slant tail EFP were proposed and studied one by one, wherein a slant tail EFP (CFEFP) having a stronger advantage than the tail skirt EFP and the straight tail EFP was proposed by Bender in 2003, a CFEFP was an EFP having a certain inclination angle between a tail fold and a Projectile axis, and Bender et al verified that the CFEFP could generate a large self-rotation speed under the aerodynamic force during flight through numerical simulation and a live-action experiment, and had excellent long-range flight stability and accuracy of an end-point target. The influence of the shell, which is one of the key components, on the performance of the EFP has been studied in the last decades, and research shows that the structure of the shell has a great influence on the forming speed and the form of the EFP, and that obtaining the EFP with a specific structure and function by using a special-shaped shell is a feasible way.
With the protection armoring of targets such as various land vehicles, large and medium-sized naval vessels on water surfaces, aerial accurate guidance ammunition and the like, the EFP applied to the terminal sensitive ammunition and the medium-short-burst high-pass flying top-attacking weapon system is more and more taken into consideration as a key damage element to realize the subsequent damage power of the target in the armor, and the traditional EFP takes a large number of secondary fragments behind the target as a main subsequent damage power source. However, the killing effect is single, the range is small, the duration is short, especially for a protective structure with a lining behind an armor, the fragment cloud behind a target is greatly reduced, and the damage capability to personnel, electronic equipment and the like inside the armor is weak.
In recent years, active Materials (RMs) are inert at normal temperature and normal pressure, and undergo chemical energy release reaction after being strongly impacted by a dynamic load (such as high-speed impact and explosive loading), even have strong explosion-like action, so that RMs is adopted to replace the traditional inert Materials as a novel damage element, and the trend of technical development is realized; at present, a great deal of RMs application research is carried out in a fragmentation part, an energy-gathering jet part and a armor piercing part, and the high-efficiency damage to various soft and hard targets is realized by utilizing the combined action of kinetic energy penetration and similar explosion reaction. Particularly, RMs is prepared into a liner, and the liner is applied to the shaped charge warhead to obtain stronger destructive power than the traditional inert shaped charge destructive elements such as soft iron, copper, tantalum and the like. Although RMs developed and prepared at the present stage is various, excellent dynamic mechanical properties similar to those of traditional inert EFP cover materials such as red copper, soft iron and the like cannot be obtained, and the formability of a single shaped charge cover prepared by RMs under explosive loading cannot be guaranteed.

Has the advantages that:
1. the EFP warhead of the invention compounds the stepped shell and active compound liner structure, it utilizes the influence of stepped shell to explosive charge detonation capacity, make the active compound liner form under the explosive drive into the compound EFP that has inertia forebody and active afterbody constitution of the oblique tail wing structure destroys the yuan, on the one hand, because the radial thickness of the periodic variation section of circumference of the stepped shell changes gradually from thin to thick in a variation cycle, explosive charge detonation product is restrained by it, expand the range from big to small gradually in radial, therefore, the detonation impulse that the active compound liner receives different areas of circumference also distributes from small to big periodically, produced the similar velocity distribution, will produce the oblique tail wing structure with the axis has an inclination angle in the deformation stage of the active compound liner; meanwhile, due to the periodic change of the radial thickness of the circumferential periodic change section of the stepped shell, the finally formed composite EFP damage element has the inclined tail wing structures with the same number of the periodic times as the periodic times, can play the same role as the inclined cutting/inclined tail wing of the rolling spinning missile, generates a steering torque under the action of aerodynamic force, enables the composite EFP damage element to generate self-rotating speed, and can greatly improve the stability of long-distance flight and the accuracy of hitting;
on the other hand, the inert precursor coats the active afterbody to avoid releasing energy in advance when penetrating the first layer of armor until the active afterbody is broken under the impact action after penetrating the first layer of armor and starts to react violently, so that the aftereffect damage effect of the inert precursor on a target can be effectively enhanced.
2. Since the sharp active energy release reaction of RMs under high speed impact is the root cause of its enhanced aftereffect power compared to traditional inert materials, great progress has been made in the research of active jet application; compared with a jet damage element, the EFP has the problems of high-speed large deformation such as turnover, injection, stretching and the like under explosive loading, and explosive formability, and particularly, when a stepped shell is used for generating an inclined tail wing structure, the circumferential edge of the shaped charge cover needs to be kept from being broken to generate periodic folds; according to the specific structural design of the active composite liner, an inner liner close to explosive charge is designed into the active liner, an outer liner far away from the explosive charge still adopts a traditional mature inert liner, and the active composite liner can be formed into a composite EFP damage element with precursor inertia and afterbody activity under the drive of explosive charge explosion; after the explosive is detonated, the inert outer cover deviating from the explosive is greatly influenced by the stepped shell, can form a complete and effective oblique tail wing structure and is used as an outer layer for coating an active rear body to drive the composite EFP damage element to spin under the action of aerodynamic force; meanwhile, when the first layer of armor is penetrated, the inert precursor on the outer layer firstly impacts the target plate, most of erosion and crushing caused by strong impact damage are only generated on the inert precursor in the plastic penetration stage, the active afterbody in the inner part is protected, the active afterbody is prevented from reacting and releasing energy in advance before the target and in the penetration process until the first layer of armor is penetrated, the active afterbody is impacted and crushed, the energy is released by violent reaction, most of chemical energy is released behind the target, and the subsequent damage power to the target behind the target is greatly enhanced.
