This program will demonstrate how additive manufacturing technologies can be used with reactive and high energy materials to create rapid and flexible fabrication of payload and munitions. Our primary approach to this problem will be to use powder bed binder printing techniques to print reactive structures. The anticipated feedstock will consist of composite particles containing all reactant spe ...

While aluminum casing materials provide some enhanced performance and thermal loading to explosive ordinance, their overall effectiveness is highly limited by incomplete combustion and long residence times. In order to reduce these problems, the casing material must be designed to facilitate rapid fragmentation through either specialized casing geometries or greatly refined initial particle sizes. ...

A compact laser driver will allow photoconductive semiconductor switches to be used in small EMP simulator "building blocks" (EMPBB). Combined with a battery powered on-board pulsed power system, these EMPBBs will allow the construction of flexible EMP test facilities with nothing more than a single fiber optic timing connection to each EMPBB.

For effective protection against EMP and HPM threats, it is important to understand the physics of the threats, and also to quantify the effects they have on electrical systems. EMP and HPM vulnerability testing requires delivery of high peak power and electric fields to distant targets. The most practical solution to simulate such environments is to develop a modular, optically-isolated MV-antenn ...

Vibrant Corporation and Sandia National Laboratories (SNL) propose to apply Process Compensated Resonance Testing (PCRT) to the DLA's need for an NDI method to detect counterfeit, nonconforming and improperly processed materiel. PCRT collects and analyzes the resonance frequencies of a component to detect structural defects, characterize material, analyze population variation, monitor manufacturin ...

The introduction of substandard or counterfeit materials into the DoD supply chain can have extremely expensive, and potentially life threatening, consequences. Current techniques used to detect nonconforming materiel can be destructive (e.g., manual sectioning and inspection of a part), time consuming and expensive (e.g., micro-computed tomography, ultrasound), or provide only limited informatio ...

Triton Systems, Inc. and its academic partner are proposing to fabricate an innovative highly conductive and transmissive thin layer to replace ITO on large area, lightweight solar cells. Part of the proposed approach will be to texture the surface of the coating to improve light transmission into the solar cell. Triton will work with a manufacturer of flexible solar panels for the Army, who wil ...

Thin-film, lightweight, large-area flexible inorganic solar cells have shown promise to meet the militarys remote power needs on the battlefield. However, thin film solar cells normally have inferior conversion efficiencies due to limited absorption of sunlight by the thin active layer. Various approaches have been investigated to improve conversion efficiencies of thin film solar cells. Among the ...

Laboratory investigations have suggested that acoustically or vibrationally inducing motion in buried targets can aid in improving target detectability through a characteristic response related to differential target motion. This gain is realized by adding an additional degree of freedom, modulation due to motion in the GPR return signal, to use as a discriminating feature. The AKELA team is propo ...

White River Technologies, Inc. (WRT) and University of Vermont (UVM) present this proposal, "Acoustically/Vibrationally Enhanced High Frequency Electromagnetic Detector for Buried Landmines". Among the primary gaps in our current landmine detection technology base is the ability to detect a wide range of buried explosive hazards including emerging low-metal mines and improvised explosive devices ...
