A 24-month Phase II project is proposed to develop and implement models that capture the fidelity of high fidelity physics-based (HFPB) models in a fast-running format. It is anticipated that such models will be incorporated in certain modules of theModular Effectiveness/Vulnerability Assessment (MEVA) code developed for and currently used by the Air Force for assessing munitions effectiveness an ...

A DYNAMIC ATTRIBUTE SPECIFICATION AND ATTACHMENT KIT (DASAK) IS PROPOSED TO SERVE AS A SUPPORT COMPONENT FOR THE RAPIDLY RECONFIGURABLE CREWSTATION (RRC) PROGRAM. A DASAK WILL PROVIDE A USERFRIENDLY INTERFACE TO COCKPIT DESIGNERS WITHOUT PROGRAMMING EXPERIENCE FOR DEFINING DYNAMIC ATTRIBUTES AND ATTACHING THEM TO GRAPHIC OBJECTS, SUCH AS TARGET AIRCRAFT, WEAPONS, ETC., WHICH ARE FOUND IN COCKPIT D ...

SUCCESSFULLY APPLYING MODEL-BASED REASONING TO REAL WORLD VISION PROBLEMS (E.G. AUTOMATIC TARGET RECOGNITION ?ATR?) REQUIRES ACCURATE REPRESENTATION OF COMPLEX RELATIONSHIPS AMONG THINGS IN THE WORLD AND OBSERVABLE IMAGE FEATURES. EVIDENCE ACCRUAL TECHNIQUES MUST BE ABLE TO OPERATE OVER THESE RELATIONSHIPS WITH LITTLE LOSS IN INFORMATION. CURRENT TECHNIQUES SUCH AS BAYESIAN NETWORKS SHOW PROMISE, ...

COMPUTED TOMOGRAPHY (CT) IS RAPIDLY BECOMING AN IMPORTANT COMPLEMENT TO OTHER NON-DESTRUCTIVE EVALUATION (NDE) METHODS AND IS THE PREFERRED NDE TECHNIQUE WHENEVER THE PRIMARY GOAL IS TO LOCATE AND SIZE PLANAR AND VOLUMETRIC DETAIL IN THREE DIMENSIONS. HOWEVER, MODERN MILITARY CT SYSTEMS ARE CAPABLE OF GENERATING MORE THAN A GIGABYTE OF CT INSPECTION DATA PER DAY--AND EVEN HIGHER DATA RATES CAN BE ...

THE DEVELOPMENT OF ANALOG DEVICES FABRICATED ON DEFECT-FREE ADVANCED SUBSTRATES WITH INCREASED NEUTRON TOLERANCE IS PROPOSED. THIS CONCEPT WILL IMPLEMENT ULTRA-THIN, DEFECT-FREE, SILICON-ON-INSULATOR SUBSTRATES FABRICATED BY BONDING AND ETCH BACK (BESOI) TO DEMONSTRATE LATERAL BIPOLAR DEVICES WITH EXTREMELY LOW BASE RESISTANCE AND RECOMBINATION VOLUME. DEVICES WITH A CUT-OFF FREQUENCY IN EXCESS OF ...

HIGH-RESOLUTION COMPUTED TOMOGRAPHY SHOWS SIGNIFICANT PROMISE IN AIDING THE DEVELOPMENT OF ADVANCED COMPOSITE MATERIALS WHICH ARE IMPORTANT IN IMPROVING AIRCRAFT PERFORMANCE. NONDESTRUCTIVE IMAGING OF THE INTERNAL STRUCTURE OF THESE MATERIALS CAN HELP IN IMPROVING PROCESSING QUALITY, IN DEVELOPING PERFORMANCE MODELS, AND IN EVALUATING MANUFACTURED COMPONENTS. CURRENT IMAGING PERFORMANCE COULD BE S ...

THE OBJECTIVE OF THE PROPOSED WORK IS TO DEVELOP TECHNIQUES FOR DETECTING AND QUANTIFYING WEAK OR "KISSING" DEBONDS IN SOLID ROCKET MOTORS. THE PROPOSED TECHNIQUE IS BASED ON X-RAY COMPUTED TOMOGRAPHY.IT IS INNOVATIVE BECAUSE IT DOES NOT REQUIRE THAT ANY GAPS IN THE DEBOND AREA BE RESOLVED. INSTEAD, IT RELIES ON MEASUREMENTS OF THE PROPELLANT DILATATION NEAR THE BONDED INTERFACE TO SHOW WHETHER LO ...

The objective of this SBIR project is to develop enhanced capabilities to evaluate solid rocket motors (SRMs) using x-ray computed tomography (CT) inspection. In Phase I, approaches were defined for developing technology to improve CT inspectioncapabilities. In Phase II, the technology will be developed and incorporated in practical tools to be delivered to OO-ALC at Hill AFB, where Air Force mi ...

The intent of this Phase I effort was to examine the feasibility of using C-C composite for possible tribological applications in Space. In the Phase I effort, selected C-C composite materials were modified and tested for both high-speed bearing cage andslip ring/ brush applications under simulated space environments. 2D C-C cage materials were modified to reduce its pore size for lubricant retent ...

AN INNOVATIVE APPROACH TO DESIGNING AN ADAPTIVE BBT MISSILE AUTOPILOT USING A TECHNIQUE KNOWN AS GSLQ IS THE BASIS OF THE FOLLOWING PROPOSAL, THE BENEFITS OF WHICH INCLUDE: (1) BEST TRADEOFFSBETWEEN PERFORMANCE AND ROBUSTNESS AMONG DIFFERENT DESIGN METHODOLOGIES; (2) THE ABILITY TO ACHIEVE LOOP TRANSFER FUNCTION RECOVERY (LTR) EXACTLY, AND NOT ASYMPTOTICALLY; (3) ADDITIONAL POLE PLACEMENT CAPABILI ...
