IN THIS PROJECT, FAILURE ANALYSIS ASSOCIATES (FAAA) PROPOSES TO EVALUATE AND DEVELOP TECHNIQUES THAT MAY PROVIDE THE BASIS FOR USING CT DATA TO DETECT AND ASSESS THE NATURE OF SUB-PIXEL FEATURES IN ROCKET MOTOR COMPONENTS. FAAA PLANS TO APPLY NDE DATA ANALYSIS AND DISPLAY TECHNOLOGY, THAT WE HAVE BEEN DEVELOPING UNDER IR&D FUNDING. THE FAAA SYSTEM UTILIZES THE PIXAR IMAGE COMPUTER, IN CONJUNCTION WITH FAAA DEVELOPED IMAGE PROCESSING SOFTWARE. FAAA HAS PREVIOUSLY DEMONSTRATED THE CAPABILITY OF THIS SYSTEM TO IDENTIFY MATERIAL DEFECTS IN A PRACTICAL MANNER. FAAA WILL APPLY SIMILAR TECHNIQUES TO THE PROBLEM OF DETECTING FEATURES AT THE SUB-PIXEL LEVEL. AS WITH LARGER DEFECTS,THE PIXAR PROVIDES THE UNIQUE CAPABILITY TO OPERATE ON LARGE AMOUNTS OF DATA IN NEAR REAL TIME AND TO PROVIDE THREEDIMENSIONAL IMAGES OF THE DATA. APPLICATIONS OF THE FAAA NDE DATA ANALYSIS SYSTEM TO THIS PROBLEM WILL BE EVALUATED IN PHASE I, WHICH WILL PRODUCE A PLAN FOR DEVELOPMENT OF A PRACTICAL CAPABILITY IN PHASE II.

THE LONG-TERM OBJECTIVE OF THIS PROGRAM IS TO PROVIDE A SUPERIOR, LOW-NOBLE-METAL-CONTENT ALLOY SYSTEM HAVING METAL/CERAMICS COMPATIBILITY AND BIOCOMPATIBILITY AT A LOWERCOST THAN THE PRESENT HIGH-NOBLE ALLOYS. THE COMBINATION OFTHE PERFORMANCE AND COST FACTORS OF THIS ALLOY SYSTEM WILL ALLOW IT TO REPLACE NOBLE METAL AND BASE METAL ALLOYS FOR DENTAL RESTORATION. THE AIM OF THE PHASE I PROJECT IS TO EXPLORE THE DESIGN AND FABRICATION OF DUPLEX ALLOYS ON CROWNS USING RAPID SOLIDIFICATION AND CASTING TECHNOLOGY. CONSEQUENTLY, MATERIALS WILL BE CHARACTERIZED AND TESTED FOR DEMONSTRATIONOF METAL/PORCELAIN COMPATIBILITY, CORROSION RESISTANCE, AND FIT ACCURACY. THE IMPROVED-PERFORMANCE DUPLEX ALLOYS WOULD BE SYNTHESIZED USING CURRENT WELL-KNOWN DENTAL MATERIALS, SUGGESTING THAT THERE COULD BE RAPID ACCEPTANCE OF THESE DUPLEX ALLOYS BY THE DENTISTRY COMMUNITY. THESE MATERIALS OFFER THE OPPORTUNITY TO REPLACE BASE METAL ALLOYS, WHICH HAVE TOXICITY PROBLEMS, WITH A MATERIAL HAVING THE DESIRABLE CHARACTERISTICS OF HIGH-NOBLE ALLOYS AT REDUCED COST.

THE CONTINUED PROGRESS BEING MADE IN LIQUID-METAL-COOLED NUCLEAR REACTORS REQUIRES A CAPABILITY TO MONITOR AND INSPECT REACTOR INTERNALS. SINCE THE 1960S RESEARCH IN ULTRASONIC IMAGING HAS BEEN PURSUED AT A SOMEWHAT LEISURELY PACE. SIMPLE SONIC ECHO RANGING HAS BEEN THE PRINCIPLE RELIED UPON TO GENERATE IMAGES OF INTERNALS. THIS REQUIRES A PRECISE MECHANICAL MEANS TO SCAN THE ULTRASONIC BEAM OVER THE OBJECT TO BE IMAGED. THIS PROJECT CONSIDERS AN ALTERNATIVE, A DEVICE WITH NO MOVING PARTS OTHER THAN AN ARM FOR AIMING IT. THIS DEVICE WILL CONSIST OF A CIRCULAR ARRAY OF ULTRASONIC ELEMENTS, EACH PRODUCING A DIVERGING CONE OF SOUND. THESE ELEMENTS WILL BE ENERGIZED BY A FREQUENCY-SWEPT SIGNAL, AND THE ECHO RETURNS WILL BE USED TOSYNTHESIZE A RADIAL ARRAY EXTENDING FROM EACH ELEMENT TO THECENTER. THIS FILLED DATA ARRAY WILL THEN BE USED TO RECONSTRUCT A THREE-DIMENSIONAL IMAGE OF THE OBJECT'S SURFACE.

OCCUPANT PROTECTION IN VEHICULAR SIDE IMPACT CRASHES IS AN IMPORTANT THEME OF THE '90S FOR THE DEPARTMENT OF TRANSPORTATION, FOR AUTOMAKERS, AND FOR INDEPENDENT RESEARCHERS. DEVELOPMENT OF OCCUPANT PROTECTION METHODS REQUIRES ACCURATE MEASUREMENT OF CONTACT VELOCITY IN SIDE IMPACT TESTS. MICROWAVE INTERFEROMETRY (MI) IS PROPOSED AS A MEANS TO MEASURE DOOR/OCCUPANT VELOCITIES IN SIDE IMPACT TESTS. MI IS EXTREMELY ACCURATE, AND MI-BASED SENSORS CAN BE CONFIGURED IN SMALL PACKAGES THAT ARE NEARLY IMMUNE TO HOSTILE ENVIRONMENTS. IN ADDITION, UNLIKE ITS OPTICAL ANALOGUE, MI DOES NOT NEED CUBE CORNER REFLECTOR DEVICES AND ACCURATE ALIGNMENT. THE APPLICABILITY OF MI WILL BE STUDIED AND COMPARED TO CONVENTIONAL MEASUREMENT METHODOLOGIES. A SIMPLE MI INSTRUMENT WILL BE USED TO MAKE ACTUAL MEASUREMENTS IN SEVERAL CRASH TESTS. HIGH SPEED FILM AND OTHER CONVENTIONALDISPLACEMENT INSTRUMENTATION WILL PROVIDE DATA FOR EVALUATION OF THE MI PERFORMANCE. MI IS IDEALLY SUITED TO CRASH TEST MEASUREMENTS. BECAUSE THIS MEASUREMENT METHODOLOGY WILL GIVE EXTREMELY ACCURATE RESULTS FOR A WIDE RANGE OF SPEEDS, AND BECAUSE IT IS NEARLYIMMUNE TO VERY HOSTILE ENVIRONMENTS, IT CAN BE USED IN MANY OTHER APPLICATIONS. IN ADDITION, MI IS INEXPENSIVE ENOUGH TO BE USED IN DESTRUCTIVE APPLICATIONS.

THE OBJECTIVE OF PHASE I IS TO DEVELOP A SPECIAL RELIABILITY ANALYSIS ALGORITHM FOR DIESEL ENGINES THAT ACCOUNTS FOR THE COMPLEX FACTORS AND SEVERE ENVIRONMENTAL CONDITIONS EXPERIENCED IN MILITARY APPLICATIONS. A RELIABILITY, AVAILABILITY, MAINTAINABILITY (RAM) MONTE CARLO SIMULATION APPROACH IS PROPOSED TO BE INTEGRATED WITH EXISTING FAULT TREE ANALYSIS SOFTWARE FOR EFFICIENT PREDICTION OF DIESEL ENGINE SYSTEM-SPECIFIC RAM CHARACTERISTICS. BY DELEGATING THE DETAILED RELIABILITY MODELING TO FAULT TREE PROGRAMS, THE RAM SIMULATION CODE CAN BE STREAMLINED, MAKING IT ECONOMICAL FOR STUDYING RAM POLICY DECISIONS WHILE MAINTAINING MODEL SENSITIVITY TO ALL SIGNIFICANT RELIABILITY FACTORS. THE PECULIAR COMPLEX INTERRELATIONSHIPS BETWEEN COMPONENTS OF A DIESEL ENGINE WILL BE REPRESENTED IN THE PROPOSED APPROACH.
