Energy focussing

摘要

A method of producing a localized concentration of energy includes providing a series of projectiles and firing the projectiles at a target. An apparatus for producing localized concentration of energy includes: a mechanism to provide a series of projectiles and a mechanism to fire the projectiles at a target. The target is configured such that upon striking the target, a projectile traps and compresses a volume of gas between the projectile and the target. The target and the projectile are also configured such that impact of the projectile onto the target gives rise to a converging shockwave inside the trapped volume of gas.

1. A method of producing a localised concentration of energy comprising:
providing a series of projectiles and firing said projectiles at a target, wherein said projectiles have a radius of curvature and said target comprises a concave surface at the point of impact of the projectiles, the concave surface having a radius of curvature at the point of impact of the projectiles that is less than the radius of curvature of the projectiles such that upon striking said target, the concave surface at least partially receives a said projectile and said projectile traps and compresses a volume of gas between the projectile and the concave surface, such that impact of the projectile onto the target gives rise to a converging shockwave inside the trapped volume of gas.
