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 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 ...

A sensor/communications package is demonstrated that can sense the physical presence of a submerged submarine at very short range, and that can be manufactured cheaply enough to enable very high density seeding of anti-submarine barriers using environmentally benign materials. The method is based on specially designed composite sensor particles activated by the submarine propulsor wake turbulence. ...

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...

Massive blood loss is the most common cause of death in potentially survivable battlefield casualties, yet no definitive medical innovations have been made for reducing these deaths in the past several decades. It is still highly impractical to carry large volumes of refrigerated blood into battle, and substantial research for developing blood substitutes and extending the durability and portabili ...

A thick SiC epitaxy process was demonstrated by SemiSouth in Phase I, as the growth (or deposition) rate was boosted from 5 um/h to 20 um/h, and thickness uniformity was kept to 5% or below. In the Phase 2 effort, it is proposed that the processes be developed for production by re-designing and optimizing the reactor susceptor in a research reactor to minimize cost and risk. Specifically, the su ...

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 ...

In this SBIR proposal, Orora Design Technologies proposes to develop a behavioral modeling centric automated design flow and supporting CAD tools for radiation-hardened mixed-signal electronic systems. A hierarchical approach will be developed to facilitate the analysis and synthesis of mixed-signal circuits and systems, where devices and circuits are described in various abstraction levels using ...

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 ...
