Abstract

The invention relates to a preparation method for an active metal micro-projectile loading a high explosive and belongs to the field of energetic material, damage and ammunition engineering. The active metal micro-projectile loading a high explosive prepared by the preparation method combines advantages of the active metal energetic material and the high explosive: an active metal micro-projectileprojectile cloud is formed by the projectile, a trajectory of an incoming missile is roughly resolved to give a substantial flight path, and the explosive is scattered around important targets on thetrajectory or the protected important targets. For a hypersonic vehicle, the trajectory resolving and trajectory predicting and calculating pressure is reduced without capturing and tracking, so thatthe intercepting probability is improved. A shell of the micro-projectile is prepared by compounding the active meal and an adhesive. An inner charge is an existing high molecular bonding explosive or a casted mixed explosive which is sophisticated in technology. Generally, the micro-projectile is easily available in raw material, simple in process, low in cost, convenient to prepare on a large scale and feasible.

Description

technical field [0001] The invention relates to a method for preparing active metal micro-projectiles loaded with high-energy explosives, belonging to the fields of energetic materials, damage and ammunition engineering. Background technique [0002] The maximum speed of a hypersonic vehicle can reach more than 25 times the speed of sound, which cannot be captured by conventional military radar technology. The emergence of hypersonic aircraft will greatly change the existing air defense and anti-missile technology pattern, and even make the existing air defense and anti-missile system completely ineffective. Some important targets will be completely exposed to enemy firepower and subject to tactical or even strategic strikes . Traditional air defense and anti-missile technology focuses on tracking targets, calculating ballistics, and predicting rendezvous trajectories, and achieves the purpose of interception through the "scalpel" type of point-to-point precise collision or...
