FIBER REINFORCED PLASTIC COMPOSITE MATERIALS ARE AVAILABLE WITH A VARIETY OF PERFORMANCE FACTORS AND MANUFACTURING METHODS. THERE ARE SEVERAL STRUCTURAL CONCEPTS THAT CAN BE UTILIZED WITH COMPOSITES. THIS PROJECT IS TO PERFORM A FEASIBILITY STUDY TO DETERMINE THE APPLICABILITY OF FIBER REINFORCED PLASTIC COMPOSITE MATERIALS FOR COMBATANT SUBMARINE STRUCTURES. EXAMPLES OF STRUCTURES TO BE ANALYZED ...

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 ...

A PLAN FOR THE DEVELOPMENT OF A MESOSCALE WEATHER NOWCASTING SYSTEM IS PROPOSED. THAT SYSTEM WOULD BE USED AS A TACTICAL DECISION AID FOR SUPPORT OF TACTICAL ARMY OPERATIONS. THE SYSTEM WOULD BE COMPOSED OF MODULAR SENSOR PACKAGES, A TELEMETRY SYSTEM, A FLEXIBLE SYSTEM OF SENSOR DEPLOYMENT, AND A MICROPROCESSOR BASED TACTICAL COMPUTER SYSTEM FOR THE ANALYSIS AND DISPLAY OF DATA COLLECTED. THE PROP ...

THIS PROPOSAL DESCRIBES THE PHASE I DEVELOPMENT WORK FOR A DUAL OUTPUT, "FAIL-SAFE" FIBER OPTIC FUZE CONTACT TRANSDUCER FOR USE IN AIRBORNE MISSILE APPLICATIONS. THE SENSOR WOULD EXPLOIT THE SENSITIVITY OF SPECIALIZED OPTICAL FIBERS TO MICROBENDING: THIS PHENOMENON WOULD BE USED TO DETECT PHYSICAL DEFORMATION OF A MISSILE SKIN. THE OBJECTIVES OF THE PHASE I EFFORT INCLUDE RESEARCHING AND IDENTIFYI ...

THE DEVELOPMENT OF A CAPACITIVE PROXIMITY SENSOR ARRAY FOR USE IN AUTOMATED ASSEMBLY AND INSPECTION OPERATIONS IS PRO- POSED. A TWO-DIMENSIONAL ARRAY OF SMALL CAPACITIVE SENSORS DETECTS THE DISTANCE BETWEEN EACH SENSOR TIP AND THE TARGET OBJECT. WHEN TOUCHING THE SURFACE OR OPERATING AT CLOSE DISTANCE, AN IMAGE OF THE SURFACE CONTOUR IS OBTAINED. THE SENSING PROCESS IS CONTROLLED BY A MICROPROCESS ...

ULTRASONIC NONDESTRUCTIVE TESTING HAS BECOME THE METHOD OF CHOICE FOR THE QUALITY ASSURANCE OF ADVANCED COMPOSITE MATERIALS. THE PROPOSED RESEARCH PROGRAM COVERS THE DEVELOPMENT OF A COMPUTER-BASED NDT METHOD FOR DETERMINING LOCAL FIBER VOLUME FRACTION AND RESIN POROSITY IN PRACTICAL LAMINATED COMPOSITES. THE COMPUTER ALGORITHMS WILL BE BASED ON EARLIER STUDIES THAT HAVE BEEN SUCCESSFUL FOR UNIDIR ...

RECENTLY, CONSIDERABLE PROGRESS IN THE GENETIC AND MOLECULAR ANALYSES OF DEVELOPMENT HAS BEEN OBTAINED. THERE ARE POWERFUL NEW MOLECULAR TECHNIQUES THAT CAN BE APPLIED TO ANALYZE THOSE GENES IMPORTANT IN THE REGULATION OF DEVELOPMENT; HOWEVER, THOSE TECHNIQUES MUST BE USED WITH GENETICALLY DEFINED RESEARCH ANIMALS. ISOGENIC LINES ARE AVAILABLE IN THE MOUSE AND DROSOPHILA, BUT ARE NOT AVAILABLEIN T ...

THE PROGRAM GOALS FOR THE EGRESS BORING MACHINE REQUIRE A ROCK BORING SYSTEM WHICH WILL PRODUCE PENETRATION RATES OVER TEN TIMES GREATER THAN THOSE PRODUCED TO DATE UNDER SIMILAR CONDITIONS. THIS PROPOSAL IS TO DEVELOP A CUTTER SYSTEM WHICH USES THE CONCEPT OF AN INTERRUPTED DISC CUTTER. IT WILL TAKE FULL ADVANTAGE OF INDEXING BETWEEN CRATERS TO MAXIMIZE ROCK REMOVAL WHILE MINIMIZING THRUST REQUIR ...

CURRENT BEST TELEMETRY SOURCE COMBINER SYSTEMS USED AT WEAPONS TEST RANGES ARE CAPABLE OF SELECTING THE "BEST" SIGNAL FROM SEVERAL REDUNDANT SOURCES. HIGHER DATA RATES AND DETERIORATION OF TEST RANGE SNRS HAVE PRECIPITATED A REQUIREMENT FOR AN AUTOMATED TELEMETRY SIGNAL PROCESSING SYSTEM CAPABLE OF COMBINING AVAILABLE SOURCES INTO AN ENHANCED "BEST SIGNAL."
