The proposal describes a miniaturized tunable filter technology for wideband tuning in the 500 MHz to 3 GHz bands. The filters use a novel actuator to achieve a combination of wide tuning range and high-Q of the resonant elements. The filter technology can be integrated into a small surface mount package, as described in the proposal. The technology is a major step for reducing the SWAP of front- ...

The Full Authority Digital Engine Control (FADEC) controls engine operation.  It is historically mounted on the engine case to minimize the routing length of the sensor and actuator wiring.  The FADEC must be maintained below 70°C, while the environment can be as hot as 170°C.  The current design uses fuel to cool the FADEC, however, this often limits the allowable ground or flight idle time ...

Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

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 ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

By continuing teaming up with one of the most reputable university teams in THz science and technology, ArkLight proposes to carry out the tasks set for a Phase-II program following our success in Phase I. We are aimed at the further development of novel spectrometers to analyze chemicals in the vapor phase based on accurate measurements of the emission and absorption spectra due to the molecular ...

The DOD requires an environmentally friendly, rapid, and non-destructive method to selectively remove coatings from composite substrates.  Atmospheric Plasma Solutions Inc. (APS) has developed a cold atmospheric plasma process to accomplish this goal. Current processes for the removal of coatings from composite materials are slow, expensive, and potentially damaging to the environment. APS has de ...

Ribbon Mills and its subcontractor Northrop Grumman Corporation (NGC) propose a Phase II program, to continue the research into advanced complex performs concepts utilizing weaving technology applied to state-of-the-art composites to enhance the revolutionary low frequency, conformal load-bearing antenna structures (CLAS) foliage penetration ground/air moving target indicator (FOPEN GMTI/AMTI) rad ...

BDC is developing a process called SMART BLEND(TM) for inspecting blended IBRs/Blisks. IBRs are susceptible to foreign object damage and blending is a relatively low cost method using machining to repair that damage.  The difficulty is that blending changes the geometries of the blades so that they no longer meet specifications.  More specifically, blending changes the frequencies of the blades ...

THE OBJECTIVE OF THIS PROPOSAL IS TO CONDUCT PRELIMINARY TESTS ON A NOVEL CHEMISTRY WHICH COULD RESULT IN THE PRODUCTION OF A LOW COST WAFER WHICH CHANGES COLOR UPON EXPOSURE TO WARFARE GASES (WG). SIMILAR WAFERS WHICH WE DEVELOPED FOR OTHER GASES ARE ABOUT 2" X 1" X 1/16" AND WEIGH ABOUT 2.3 GM. THESE CHROMOSENSE (TM) WAFERS CAN DETECT HYDROGEN SULFIDE, ETC. IN 10-30 SEC. AT CONCENTRATIONS OF THE ...
