Abstract
A projectile is provided for use in a non-lethal weapon system. The projectile having kinetic energy is launched substantially along the longitudinal axis in the direction of a target. Upon impact of the projectile with the target an elastic mechanism absorbs elastically a first portion of the kinetic energy. A locking mechanism stores the first portion of the kinetic energy within the elastic mechanism; whereby the remaining kinetic energy of the impact is reduced to a non-lethal level of the target. The projectile preferably includes a deformable head attached to the first body. The deformable head is formed from a viscoelastic material which manifests both the elastic mechanism (with the elastic mechanical properties of the viscoelastic material) and further manifests the locking mechanism with the viscous properties of the viscoelastic material.
