Description
Technical field
Patent of the present invention relates to the passive ballistic armor materials of a kind of fluctuating type, especially relates to a kind of ballistic structure armour material that can make bullet generation rank sheer, can be used for the Protective armor of the fighting equipments such as such as haulage vehicle, tank, aircraft.
Background technology
Along with the development of modern war, fighting equipment will suffer more fatal attack in future war, can propose renewal, higher requirement to guard technology.And adopting passive plate armour, the compound armor formed as homogeneous armor, composite armour, reactive armor etc. or modularization are armoring, make every effort to accomplish not breakdown.For improving the damage effects such as the running through of barrier propterty, particularly anti-bullet of armour, the blast of bomb and fragmentation damage, improving protecting factor, selecting the passive plate armour that bullet can be made to go off course, then greatly can reduce the armour-piercing kinetic energy of bullet.
Application number be 200920004650.8 a kind of module that patent discloses to put on a suit of armour the spherical Passive Defence of formula armoring; the unit module assembled by preset hemisphere spill collet, spheroid, cover plate is formed; and this element module is carried out matrix arrangement; be wrapped in the outside of protected object; utilize spheroid to produce High Rotation Speed when hit by external force thus make to attack bullet and change attack trajectory, realize the armoring performance of Passive Defence.But there is protection blind area in this element module, if projectile impact is on aspheres contact surface, then cannot avoid being hit.
Application number be 201010120575.9 patent to disclose a kind of flexible protective armoring, it is characterized in that in housing, be filled with dense thick viscous liquid, place in dense thick viscous liquid and stop net, be placed with high-strength alloy plate at the postmedian of dense thick viscous liquid.Reached the object of protection by the mode of wrapping up, clinging, being wound around and stopping, can be used for making the thicker protection shield of thickness and bulletproof armour.But, the dense thick viscous liquid parcel effect of clinging that this invention adopts is very faint for the effect of high velocity bullet, and stopping that the winding cushioning effect of net and strengthened rope is also limited, the penetrability finally for decomposition and absorption bullet only rests on low velocity slug impact events.
Application number be 201120517203.X patent discloses a kind of additional reactive armor turned to, it is characterized in that cellular construction is a steel plate box, a built-in concave bottom, fuse and explosive are equipped with in the inside.By increasing turning function on reactive armor, realize the object limited explosions orientation being passed on penetration bullet.Its built-in detonating explosive speed is exceedingly fast, but cannot resist the secondary penetration of bullet.
Therefore, the present invention proposes the passive ballistic armor materials of a kind of fluctuating type, according to the program of input, fluctuating plate armour can carry out amplitude, speed, frequency adjustment according to battlefield situation, conversion fluctuating attitude, to make to greatest extent to attack bullet driftage, containment objective.
Summary of the invention
