US Patent 10451378 Reverse velocity jet tamper disrupter enhancer

Provided herein are fluid jet enhancement adapters for use with a propellant driven disrupter. The adapter may comprise: a first end operably connected to a muzzle end of a propellant driven disrupter barrel and a second end, wherein a longitudinal region extends between the first end and the second end. The longitudinal region has: a longitudinal region inner surface that defines a longitudinal region lumen; a longitudinal region outer surface opposably facing the longitudinal region inner surface, with a longitudinal region wall having a wall thickness that separates the longitudinal region inner surface from the longitudinal region outer surface. The longitudinal region lumen has a first end inner diameter that is substantially equivalent to a muzzle inner diameter. The longitudinal region wall forms a continuous surface that radially isolates the longitudinal region lumen from a surrounding environment.
