Description
Technical Field
The invention relates to a preparation method and an evaluation method of energy-containing micro-projectile damage cloud with a composite structure, and belongs to the field of energy-containing materials and warheads.
Background
At present, the mode of preventing the air defense and the anti-pilot warhead from damaging the target is mainly implemented through a fragment field and shock waves formed by the explosion of the warhead after the missile directly hits the target or approaches the target. Direct targeting without precision guidance fuses is difficult to achieve with conventional weapon munitions, and the impact destructive effect of the shock wave decays rapidly with increasing distance. Therefore, the damage to the target by the fragment field generated after the blast of the warhead is the most common damage way. However, since the conventional warhead uses the inert tungsten alloy as the fragment, there are disadvantages in the following aspects: (1) the effective killing radius of the fragments is only meter-order, under the condition of high relative speed of the bullet eyes, the requirement on accurate guidance is extremely high, the target can be hit only within a very small range of miss distance, and the 100% killing probability is difficult to meet; (2) in order to ensure that the fragments can effectively puncture the target, the fragments need to have higher kinetic energy and larger mass, so that the number of the fragments is inevitably greatly reduced, and the target quantity on a unit area is limited; (3) in pursuit of guidance accuracy, the weight of the warhead must be sacrificed, and the payload of the warhead is reduced, thereby reducing the cost-effectiveness ratio of the warhead. In addition, studying the damage effect on the target under different fragment scattering situations is one of the important factors for measuring the damage performance of the target and making damage assessment. The scattering situation of a fragment field formed by the blast of a warhead in the space is random and uncertain, so that the striking effect of fragments on a target is random and uncertain when the target is damaged, and the target presents different damage degrees after being struck. Therefore, at present, the correlation calculation method for the fragment scattering situation model and the target damage established under different intersection conditions is complex and tedious, and meanwhile, the after-effect damage effect of the active fragment cannot be coupled in, so that the method is unreliable.
Disclosure of Invention
The invention aims to solve the problems of small killing radius, high guidance precision, single damage mechanism, low damage cost ratio and complex and fussy damage evaluation method of the conventional warhead using inert tungsten alloy as a damage element at present, and solve the technical problem that the conventional air defense reverse guidance mode is difficult to form substantial threat on a high-speed aircraft.
The invention relates to a preparation method and an evaluation method of energy-containing micro-projectile damage cloud with a composite structure, wherein the energy-containing micro-projectile with the composite structure is an energy-containing micro-projectile with a core-shell structure and consists of a high-activity energy-containing core material with an impact reaction characteristic and a high-strength energy-containing shell material. The traditional high-molecular-based energetic fragment has high energy and high activity, but the mechanical property is brittle, and the integrity of the fragment can not be maintained when the explosive is driven to be thrown. Although the traditional metal-based energetic fragment has better mechanical property by adding an inert metal component, the energy and the activity per se are reduced, the density and the weight are increased, the damage effect on a target plate is reduced, and the density and the range of the energetic fragment cloud are also reduced. Compared with the prior art, the composite structure energetic micro-projectile has excellent energy release characteristics, also has extremely high strength and lower density, usually has enough passivity to maintain the structural integrity under the static or quasi-static load condition, has extremely strong penetration capability when initiating impact on a target, can realize multiple strikes of blasting effect, high temperature effect and pilot effect as active fragments, and has great development potential in the national defense fields of air defense and anti-conductance and the like.
The energy-containing micro-projectile damages the cloud, namely, a large amount of energy-containing micro-projectiles are filled in the warhead, and are scattered by the warhead to form a large-area energy-containing fragment cloud cluster, and a large-area sealing area is formed in front of a target trajectory. When the target passes through the energy-containing fragment cloud cluster, the energy-containing micro-projectile impacts the target and then pre-damages the heat-proof structure to destroy the heat balance of the target, so that the heat-proof structure is locally and seriously ablated, further the damage such as perforation, breakage or falling is generated, and finally the target is disintegrated or deviates from a preset trajectory. The damage mechanism of the energy-containing pellet damage cloud mainly comprises kinetic energy generated by collision of the energy-containing fragments and the aircraft, explosion energy of the energy-containing fragments, aerodynamic force and aerodynamic heat energy of high-speed flight of the aircraft, and compared with the single kinetic energy action of the conventional inert fragments, the energy-containing pellet damage cloud is a typical compound energy action.
