Fluted linear shaped charge with simultaneous initiation
10458761 · 2019-10-29 ·

This patent relates to lined shaped explosive devices, in particular it relates to linear Shaped Charges (SC), more particularly it relates to a Fluted or Scalloped Linear Shaped Charge. The fluted linear SC, unlike a standard linear SC produces hydrodynamic penetration, higher jet velocities, higher mass jets and deeper penetration. The fluted linear device disclosed herein produces greater compression and convergence of the liner material because of the partial radial collapse of the concave flutes. Further, the fluted linear SC is equipped with a simultaneous initiation of the full length of the explosive driving the liner, providing smooth detonation wave front along the full length of the fluted linear liner.

Extraction charge for underground threats

An extraction charge for threats buried underground includes a housing, a shaped charge disposed in the housing at one end thereof, and a canister disposed in the housing and spaced apart from the shaped charge. The canister defines an open-ended tubular pathway and includes an explosive material housed in a region of the canister that circumscribes the tubular pathway. A delay detonator is coupled to the shaped charge and to the explosive material.

Layered energetic material having multiple ignition points

An energetic material having thin, alternating layers of metal oxide and reducing metal is provided. The energetic material may be provided in the form of a sheet, foil, cylinder, or other convenient structure. A method of making the energetic material resists the formation of oxide on the surface of the reducing metal, allowing the use of multiple thin layers of metal oxide and reducing metal for maximum contact between the reactants, without significant lost volume due to oxide formation. An ignition system for the energetic material includes multiple ignition points, as well as a means for controlling the timing and sequence of activation of the individual ignition points. A gas producing layer is also provided to increase pressure.
