Description
Technical Field
The invention relates to a preparation method and an evaluation method of high-activity energy-containing pellet damage cloud, 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 efficiency and cost ratio of the conventional warhead using inert tungsten alloy as a damage element and the complexity and complexity of a damage evaluation method caused by the conventional warhead, and solves the technical problem that the conventional air defense reverse guidance mode hardly forms substantial threat on a high-speed aircraft, and provides a preparation method and an evaluation method of high-activity energetic micro-projectile damage cloud.
The invention relates to a preparation method and an evaluation method of damage cloud of a high-activity energy-containing micro-projectile, wherein the high-activity energy-containing micro-projectile is a metastable state energy-containing composite material with a core-shell structure, and the metastable state energy-containing composite material consists of an outer layer of inert high polymer and an inner layer of active metal powder. The high-activity energy-containing micro-projectile has a certain density and strength besides an excellent energy release characteristic, usually has enough passivity under a static or quasi-static load condition to keep the structural integrity, has stronger penetration capability when initiating impact on a target, can realize multiple strikes of a blasting effect, a high-temperature effect and a pilot effect as an active fragment, and has great development potential in the national defense fields such as air defense and guidance.
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.
