THE OBJECTIVE OF THIS EFFORT IS TO ASSESS LIGHTWEIGHT STRUCTURAL COMPOSITE MATERIALS WITH GREATLY IMPROVED FLAMMABILITY, SMOKE GENERATION, AND TOXIC FUME GENERATION (FST) PROPERTIES FOR USE IN NAVY INTERNAL SUBMARINE APPLICATIONS. THE MATERIALS TO BE EVALUATED CONSIST OF GLASS REINFORCING FIBERS BLENDED IN A THERMOPLASTIC MATRIX WITH PRECISE FIBER/RESIN VOLUME FRACTION CONTROL. THE THERMOPLASTIC ( ...

FOR PHASE I, AMSI PROPOSES TO IDENTIFY AND ESTABLISH THE TECHNICAL FEASIBILITY OF VARIOUS ADVANCED ACOUSTIC ARRAY CONCEPTS. THREE GENERIC APPROACHES ARE CURRENTLY IDENTIFIED: 1) OPTIMIZE THE SENSOR DESIGN (I.E., DIRECTIONAL SENSORS, ETC.), 2) OPTIMIZE HYDROPHONE/ GROUP/ARRAY GEOMETRY (I.E., MULTI-APERTURES, ETC.), AND 3) IMPLEMENT SIGNAL PROCESSING TECHNIQUES (I.E., VARIOUS ANALYTIC CONTINUATION T ...

THE NEED FOR SOPHISTICATED DATABASE MANAGEMENT SUPPORT IN NAVY COMMAND AND CONTROL SYSTEMS CONTINUES TO GROW. HOWEVER, CONVENTIONAL DATABASE MANAGEMENT STRATEGIES AND TECHNIQUES ARE NOT CURRENTLY MEETING THE UNIQUE NEEDS OF NAVY DECISION SUPPORT SYSTEMS, WHICH REQUIRE EXTENDED CAPABILITIES FOR HANDLING UNCONVENTIONAL DATA FORMATS AND TEMPORAL INFORMATION. IN THIS PROPOSAL, AQUIDNECK MANAGEMENT ASS ...

AN OBJECTIVE OF THIS PROJECT WILL BE THE DEVELOPMENT OF NEW AND NOVEL THERMOPLASTIC POLYMER ALLOYS WITH HIGH RESISTANCE TO ALL KNOWN HAZARDOUS CHEMICALS. A FURTHER OBJECTIVE WILL BE TO CROSSLINK INDIVIDUAL POLYMERS IN THESE ALLOYS TO FORM NON-MELTING INTERPENETRATING POLYMER NETWORKS (IPN'S) WHICH WILL EXHIBIT GREATER RESISTANCE TO HAZARDOUS CHEMICALS THAN THE THERMOPLASTIC ALLOYS FROM WHICH THEY ...

IT IS PROPOSED TO USE PHASE I TO ASSESS THE APPLICABILITY OF A NEW ULTRASONIC HEAD-TRACKER SYSTEM DEVELOPED FOR HELICOPTER USE BY AEG, A PROTOTYPE OF WHICH COULD BE MADE AVAILABLE TO W.W. GAERTNER RESEARCH, INC. FOR THIS TEST. IF THE ACCURACY OF THE ORIGINAL PROTOTYPE IS NOT ADEQUATE, SEVERAL DESIGN IMPROVEMENTS ARE SUGGESTED WHICH COULD BE IMPLEMENTED UNDER PHASE II.

A PRELIMINARY DESIGN OF A PROJECTOR IS PRESENTED, BASED ON THE FITZGERALD FLEXBAR, THAT HAS AN ACOUSTIC OUTPUT AT FR 1000 HZ OF SOMEWHAT BETTER THAN 100 WATTS, WITH A QM 5 AND EFFICIENCIES OF 65 - 70%. THE PROPOSED FLEXDUCER MODULE IS 15" (...) IN DIAMETER BY 15" (...) HIGH AND CONSISTS OF 36 CERAMIC FLEXBARS, NODALLY MOUNTED IN TWO TIERS OF 18 EACH. THE PROJECTOR IS AIR-BACKED AND CARRIES ITS OWN ...

KVH INDUSTRIES PROPOSES TO DEMONSTRATE THE FEASIBILITY OF DEVELOPING A MINIATURIZED ORTHOGONAL MAGNETIC SENSOR ASSEMBLY WHOSE VOLUMETRIC DIMENSION, INCLUDING SHIELD, WILL NOT EXCEED 10 CM(3). THE UNIT HAS AS OBJECTIVES A SENSITIVITY OF 1 NANOTESLA WHILE OPERATING AT FLUX DENSITIES OF UP TO 20 OERSTED. FURTHERMORE, THE SYSTEM DRIFT AT ROOM TEMPERATURE IS NOT TO EXCEED 1 NANOTESLA WITHIN A 60 MINUTE ...

THE APPLICATION OF EMERGING COMPUTER TECHNOLOGIES FORMULATE AN OPPORTUNITY TO DEVELOP COMPUTER-AIDED LOGISTICS SUPPORT SYSTEMS. PROVISIONING/SUPPLY SUPPORT, A MAJOR ELEMENT OF INTEGRATED LOGISTICS, IS AN IDEAL CANDIDATE FOR THE APPLICATION OF COMPUTER-AIDED LOGISTICS SUPPORT TOOLS. THIS PROPOSAL WILL (1) DEFINE THE REQUIREMENTS FOR TRANSITIONING CURRENT PROVISIONING/SUPPLY SUPPORT PRACTICES AND PO ...

THE POTENTIAL TECHNOLOGICAL IMPORTANCE OF MULTICOMPONENT ULTRAFINE MICROSTRUCTURES MAKES IT ESSENTIAL TO DEVELOP METHODS OF FORMATION WHICH PERMIT BOTH HIGHER GROWTH RATES AND IMPROVED CONTROL OVER MATERIAL PROPERTIES. WE PROPOSE A NEW TECHNIQUE, "GAS JET DEPOSITION", THAT HAS THE POTENTIAL TO PROVIDE THESE CAPABILITIES AND OTHER ADVANTAGES OVER ESTABLISHED METHODS. IN THIS TECHNIQUE, DEPOSITING A ...
