In an effort to development more robust optical system coatings DTRA, in collaboration with Sandia National Labs, is working to characterize the degradation of optical materials for space systems when exposed to high intensely EUV/ cold x-rays. The experiments utilizes the Double Eagle z-pinch facility which generates high current, high voltage arc pinch plasma to produce an intense EUV and cold x ...

This SBIR Phase I project will investigate the use of virtual shared memory technology as a unifying software paradigm for a cluster of shared-memory multiprocessors interconnected on a local area network or on a high-speed communication fabric. The main focus of the research will be on development of compilation and runtime systems that support a notion of data locality within a global distribut ...

This project team will fully develop and test AlphaBear 2, a vocabulary learning game for grade 4 to 7 students. Vocabulary is a prerequisite for academic success, as it is linked to stronger performance across academic subjects and improved reading comprehension. It is more difficult for students to participate in educational activities without understanding the key vocabulary associated with tha ...

In a previous effort, GTL successfully demonstrated that the BHL cryotank technology provides a 75% mass reduction compared to the state of the art cryotanks. This capability would double the payload a liquid propellant launch vehicle just from the mass...

While guided munitions have been used with great success, the technology for these weapons is still rapidly advancing and more nations are gaining access to them. In order to fulfill its mission to assure that the US is the beneficiary of technical surp...

Exploitation of new chip-scale optical frequency comb sources demands improvements in MWIR/LWIR detector performance, including: High speed (5 GHz); high sensitivity (NEP < 1pW/Hz1/2); broad spectral response (Octave); and thermo-electric cooler (TEC) operating temperature. No existing detector meets these demanding performance parameters. Phase I successfully designed and demonstrated an octave s ...

AN EXPERIMENTAL INVESTIGATION OF INNOVATIVE FLAMEHOLDER DESIGNS TO ENHANCE MIXING IN A SUPERSONIC COMBUSTION RAMJET (SCRAMJET) ENGINE IS PROPOSED. IN A SCRAMJET ENGINE OPERATING AT HYPERSONIC FLIGHT SPEEDS,THE SHORTER RESIDENCE TIME AND DECREASED MIXING RATE CAUSE DETERIORATION IN THE COMBUSTION EFFICIENCY AS COMPARED WITH LOWER SPEEDS. TWO CONFIGURATIONS RECENTLY DEVELOPED TO PROMOTE RAPID MIXING ...

Using new low bandgap GaSb photovoltaic cells, JX Crystals has recently demonstrated functional thermophotovoltaic prototype generators. While it is generally believed that the cost of materials makes non-silicon photovoltaic cells prohibitively expensive unless one can develop thin film cells, this thesis is wrong for thermophotovoltaic cells. Specifically for the GaSb cell, the Ga and Sb mater ...

Traditional weapon systems often fail to meet the requirements of close combat typical of the previously discussed engagement, where insurgents often blend in or store weapon amongst friendly or non-combatant forces, to shield them from precision strike munitions of a technologically superior force. This type of warfare has led to an increased focus on the use of less-lethal weapons, to reduce let ...

The OrbWeaver effort addresses DoD needs for affordable, resilient SATCOM capabilities by developing a system for recycling an unmodified ESPA ring on-orbit to form a large aperture phased array capable of providing high-bandwidth SATCOM services to K-ba...
