Corvid Technologies is pleased to offer this proposal for the development of a first-principles numerical approach to modeling Solid Rocket Motor (SRMs) response to unplanned thermal stimuli. Corvid has a history of developing models for propellant violent reaction to projectile and fragment impact stimuli. We will adapt an existing heat transfer model to address SRM fast and slow cook-off due to ...

Kyma Technologies will explore aspects of seeded bulk GaN crystal growth to develop manufacturing processes for large area, high quality, semi-insulating GaN substrates for RF applications. Preparation of GaN seeds and growth thereon, including surface cleaning, off-cut angle and direction, growth initiation, and defect control will be investigated. The use of novel seeds and growth conditions wil ...

There is a need for a simple, affordable method for measuring domoic acid in the field. This project will develop a rapid, onsite kit for domoic acid featuring a filter membrane that produces a readable color response without need for instrumentation. The filter membrane contains three or more zones with different assay characteristics in close proximity. These zones will indicate different co ...

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 ...

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. ...

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 ...

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 ...

INADEQUATE STARTER FEEDS SEVERELY HOLD BACK NEW AQUACULTURE ENTERPRISES SUCH AS PRESENT ATTEMPTS TO RAISE FISHES WHOSE LARVAE DEVELOP FROM SMALL EGGS AND HAVE VERY "DIFFICULT" FOOD REQUIREMENTS. INERT LARVAL FEEDS HAVE NOT SUCCESSFULLYELIMINATED THE STRICT DEPENDENCY ON NATURAL FORAGE DURING THE CRITICAL POST-LARVAL STAGE AFTER YOLK ABSORPTION AND BEFORE THE DEVELOPMENT OF A DIGESTIVE SYSTEM WITH ...
