The development of a generalized moving body capability for Computational Fluid Dynamics (CFD) flow simulations of highly transient flowfields is critical to system analyses of Divert and Attitude Control Systems (DACS) for Kinetic Warheads (KWs). Testing capabilities are limited in the DACS operating regime; therefore, computational tools are essential for such analyses. The flow in the DACS its ...

This SBIR Phase I project will demonstrate both the technical and economic feasibility of using a fluidized bed system, initially developed for heat treatment, quenching, and aging of premium aluminum sand castings, to separate castings from sand molds, to de-core internal passageways in the castings, to reclaim the sand for re-use, and to use the binder resins from the molds and waste sand from m ...

The pressing need exists within industry to accurately measure high aspect ratio microscale structures. For example, diesel injector nozzles are manufactured with microscale holes ranging from 50-200 micrometers in diameter and 3-5 mm depths. One fundamental challenge is to nondestrucvely measure these features in order to validate models, enhance manufacturing processes, and reduce fuel emissions ...

Manning Applied Technology proposes to develop a handheld infrared spectrometer, ideally suited to detection of airborne chemical agents at and below permissible exposure limits. This approach offers unmatched sensitivity and specificity for detection of all types of chemical vapors. The instrument is modular, rugged, compact and highly sensitive. Volume pricing will be less than $1000 each. ...

The growth and fabrication of nanostructures, particularly short period Type-II superlattices, rely on high quality crystalline materials. Defects and non-planarities on the substrate surface and non-uniformities in the epitaxial layers can impair device performance. Gallium antimonide (GaSb) substrates have utility in exploring new III-V alloys and devices. While GaSb substrates are available, ...

This Small Business Innovation Research Phase I project Expedited Fabrication of Conformal Window for Airborne Laser (ABL) aims to demonstrate the feasibility of ductile mode machining (DMM) to dramatically reduce manufacturing cycle times of meter-class lightweight mirrors. DMM will drive fabrication times to less than 6 months by reducing/eliminating grinding, lapping and polishing for the ABL 1 ...

MCNC PROPOSES A FEASIBILITY STUDY AND EVALUATION OF THREE PROMISING APPROACHES TO THE FABRICATION OF SURFACE TEST STRUCTURES ON SILICON. SURFACE FEATURES ON THE FIRST STRUCTURE WILL BE PRODUCED BY CONTROLLABLY ETCHING THERMALLYGROWN OXIDES. FEATURES ON THE SECOND WILL BE MADE BY ETCHING PIEZOELECTRIC THIN FILMS. USING THE PIEZOELECTRIC FILM AS PART OF A CAPACITOR, STEP-HEIGHT CAN BE VARIED AND PRO ...

Electronic devices which operate at high temperatures could be used in many military and commercial systems. GaAs and Si based devices cannot operate at these temperatures and require cooling. Wide bandgap material such as diamond, SiC and GaN have greater breakdown voltages, higher operating temperatures, and higher saturated electron velocities than either GaAs or Si. However, these material sys ...

PLEX Corporation will demonstrate a highly efficient laser emitting light at 1100nm in the near infrared. Technical issues in laser design will be resolved in Phase I, with a full lasing test experiment in Phase 2. This laser candidate has potentially a 25% electrical efficiency and can, in principle, be scaled to high power levels. Cutting and welding applications are foreseen in the industrial e ...

A SMALL SCALE WASTE COLLECTION SYSTEM WILL BE DESIGNED AND EVALUATED TO DETERMINE POTENTIAL EFFECTIVENESS OF FOUR DIFFERENT DEGREES OF CONTAINMENT OF NET PANS; 5, 50, 60, AND100 PERCENTS. EFFECTIVENESS OF THE COLLECTION UNIT WILL BE EVALUATED BY MONITORING EFFICIENCY OF PHOSPHOROUS, SUSPENDED SOLIDS AND DOB LOAD REMOVAL AT EACH OF THE FOUR CONFIGURATIONS. OTHER OPERATIONAL AND ENVIRONMENTAL PROBLE ...
