Explosions and high-velocity impacts can create strain rates on the order of 105 to 107 s-1. To simulate these events, first-principles codes require material models that are valid at these loading rates. Currently, the amount of test data, material models and material constants for this strain rate range is extremely limited, and an innovative and cost-effective laboratory test procedure is neede ...

Nanohmics proposes to develop a hyperspectral imager for aft-looking sensing of phenomenology associated with target vehicles.The payload is designed to operate with existing components and has no moving parts.The high spectral resolution will provide feedback for signature models and the spatial resolution will allow the spectral signatures to be associated with specific phenomena.Approved for Pu ...

Applied Mathematics, Inc., proposes to implement and test multi-sensor, multi-platform data fusion software, using state-of-the-art non-linear filters. This effort supports the development of a multi-sensor, multi-geometry picture of threat scenarios, supporting requirement for a single integrated picture of the battlespace. We will test and evaluate the software using threat scenarios of interes ...

The adoption of Human-Machine Interface (HMI) technologies for BMDS planning, test and evaluation, operations, and mission control must be undertaken in a carefully planned manner. Lacking are methods to test the effectiveness of user interface technologies for improved situation awareness and decision-making ability. Knowledge Based Systems, Inc.’s (KBSI) Intuitive User Interface Technolog ...

In the Phase 1 program, ENGIN-IC studied the key technologies to develop a Solid State Power Amplifier (SSPA) to replace the Klystron Tube currently used for the Ground-based Midcourse Defense Element of the Ballistic Missile Defense System (BMDS). ENGIN-IC demonstrated a GaN Power amplifier MMIC design offering greater than 40-W saturated power with more than 45% efficiency, a 160-W sub module w ...

Ballistic missile threats include the potential for complex target scenes including countermeasures and debris in addition to lethal objects. In order to defend against this threat, the Ballistics Missile Defense System (BMDS) has been developed to intercept the targets. The construct of using multiple interceptors on a single target is both costly and taxing on the BMDS command control. However, ...

HIGH-DENSITY ENERGY STORAGE AND FAST DISCHARGE WILL BE CRITICAL IN A VARIETY OF HIGH POWER AEROSPACE APPLICATIONS. CAPACITORS ARE IDEAL FOR THESE PURPOSES, AS WELL AS FOR POWER CONDITIONING AND FILTERING. UNFORTUNATELY, BULK POWDER-BASED DIELECTRICS USED IN CAPACITORS HAVE SEVERE LIMITATIONS, ESPECIALLY THE HIGH NUMBER OF SHORT-INDUCING DEFECTS CAUSED BY POOR CONTROL OF MATERIAL PROPERTIES IN CERA ...

An innovative discharge geometry for a very compact, area cooled, high average power CO2 laser employing a two mirror, waveguide-stable optical cavity is proposed. The specific Phase I result sought is the generation of an average CO2 output power of 1 W/cm2 of wall cooling area in a geometry that has a total cooling area of 140 cm2. A lightweight CO2 amplifier version of a future Phase II devic ...

Glass is an attractive material for microelectronic packaging because it is hermetically sealing, has a low coefficient of thermal expansion, and is compatible with d.c. circuits. Unfortunately, the working temperature of glass is too high for this application. Low-temperature processing of a sol-gel derived, aluminosilicate material for hermetic seals is proposed for electronic packaging. This ...
