An amputation system includes a cutting element having a cutting blade traversing a V-shape. The V-shape has a vertex and an angle in a range of 90-120&#xb0;. A rod, rigidly coupled to the cutting element, has its longitudinal axis aligned with the vertex so it bisects the angle of the V-shape. A barrel having a bore receives at least a portion of the rod therein wherein the rod's outboard end resides in the bore. An energetic energy source, positioned in the bore adjacent to the rod's outboard end, generates a pressure force that is incident on the rod's outboard end. The pressure force is one that peaks within 0.5 milliseconds to propel the rod from the bore at a velocity in a range of 300 to 1000 feet per second.

Amputation system for field use

A discrete gradient charge that has a discrete first hollow cylindrical layer of a solid first fuel, which is about 85% by weight fine aluminum powder having a median diameter of about 3.5 microns. There is a discrete second hollow cylindrical layer of a solid second fuel that is about 80% by weight coarse aluminum powder with a median diameter of about 31.0 microns. The fuels have a cured HTPB binder. A pellet of an explosive positioned within the first hollow cylindrical layer provides ignition. The fuel in the charge reacts with the surrounding air or with a hollow cylindrical oxidizer layer, or a combination thereof.

Process for additively manufacturing discrete gradient charges

An explosive ordnance disposal (EOD) tool has an inflated state and a deflated, collapsed state. In the inflated state, the EOD tool includes a central longitudinal axis and a radially outer portion. The radially outer portion contains an inflation composition. The radially outer portion includes an opening for admitting the inflation composition into the radially outer portion, an exterior wall and an interior wall that defines a through opening centered on the central longitudinal axis.
