ABSTRACT:The LWIR spectrum is well suited for moderate- to long-range free space communications because of its atmospheric window and low scattering by dust, haze, precipitation, and fog. The recent impressive laser development of QCLs is poised to provide the high speed LWIR transmitter for such a free space communication system; a corresponding advance in LWIR detectors is needed to enable the h ...

ABSTRACT:Type II strained-layer superlattice (SLS) materials are predicted to have much lower Auger recombination rates than those of HgCdTe, leading to lower dark currents; however, they are limited by Shockley-Read-Hall recombination via defect states near mid-gap. Hydrogenation is a technique that has proven to be effective in electrically passivating defects in various semiconductor-based devi ...

ABSTRACT: An organizational culture that promotes problem solving is necessary for success in any organization. Nondestructive Inspection (NDI) is the inspection of a structure or component in any manner that will not impair its future usefulness. The purpose of the inspection may be to detect flaws, measure geometric characteristics, determine material structure or composition, or it may characte ...

As the Air Force (AF) begins the progression of applying systems engineering from the top-level definition of the system architecture down to a granular level of design it is very important to also realize the changes that will be taking place through Technology Insertion initiatives. Continuous system engineering is required to preserve the integrity of a system, facilitate the development of new ...

Design Intelligence Incorporated, LLC (DII) proposes an integrated design approach for an innovative perching micro air vehicle (MAV) using energy harvesting.  The proposed design concepts will build upon DIIs proprietary energy harvesting technology and hardware and will include innovative biomimitic MAV design concepts. In particular, DII proposes MAV design concepts that focus on energy harves ...

Military aircraft are largely constructed from special aluminum alloys, which typically have secondary precipitate phases that substantially improve mechanical strength. However, these regions also promote corrosion in such common environmental conditionsas acid rain, saltwater, and thermal cycling. The problem is significant enough that the U.S. Air Force expends approximately $1 billion per ye ...

This Phase I SBIR project will demonstrate the feasibility of a novel method for monitoring volatile organic compounds (VOCs) such as ubiquitous hazardous solvents in military or industrial environments and their neighboring communities. The long-termobjective of the project is to develop and commercialize a real-time, on-line and autonomous mid-infrared laser spectrometer specifically designed fo ...

The primary objective of this proposal is to select an effective in-situ technology for remediating PCE/TCE at Tinker Air Force Base. A secondary objective of the work is to develop a protocol that can be used for identifying feasible in-situ approachesfor chlorinated solvent degradation on a site-specific basis. The four remedial technologies that will be evaluated include anaerobic dehalogenat ...

THIS PROPOSAL DESCRIBES A FEASIBILITY STUDY FOR IMPLEMENTING A REALTIME, THREE-DIMENSIONAL CLOUD MODEL TO SUPPORT REENTRY VEHICLE TEST OPERATIONS. AN EXISTING RESEARCH CLOUD MODEL WOULD BE INTERFACED TO A MESOSCALE ATMOSPHERIC MODEL. THE COMBINED MODELING SYSTEM WOULD BE ADAPTED FOR USE AT THE KWAJALEIN MISSILE RANGE (KMR). FORECASTS OF DETAILED CLOUD FEATURES SUCH AS WATER CONTENT, RADAR REFLECTI ...

THE PROGRAM GOALS FOR THE EGRESS BORING MACHINE REQUIRE A ROCK BORING SYSTEM WHICH WILL PRODUCE PENETRATION RATES OVER TEN TIMES GREATER THAN THOSE PRODUCED TO DATE UNDER SIMILAR CONDITIONS. THIS PROPOSAL IS TO DEVELOP A CUTTER SYSTEM WHICH USES THE CONCEPT OF AN INTERRUPTED DISC CUTTER. IT WILL TAKE FULL ADVANTAGE OF INDEXING BETWEEN CRATERS TO MAXIMIZE ROCK REMOVAL WHILE MINIMIZING THRUST REQUIR ...
