ATA HAS DEVELOPED SEVERAL ANGULAR SENSORS BASED ON THE MAGNETOHYDRODYNAMIC (MHD) PRINCIPLE AND CURRENTLY HOLDS A PATENT ON THE BASIC DESIGN. THE NAVY REQUIRES A PROJECTILE SPIN SENSOR WHICH CAN MEASURE THE PEAK ANGULAR VELOCITY AND INDIRECTLY, THE PROJECTILE MUZZLE VELOCITY. THIS INFORMATION CAN THEN BE USED TO SET CONTROLLED VARIABLE TIME (CVT) FUSES FOR PRECISE PROXIMITY DETONATION. AN MBD ANGUL ...

REVERSE OSMOSIS (RO) IS A PROMISING NEW PROCESS FOR SHIPBOARD PRODUCTION OF POTABLE WATER FROM SEAWATER. HOWEVER, CURRENT RO SYSTEMS SUFFER FROM TWO PROBLEMS: 1) FOULING CAUSED BY THE FEED STREAMS,AND 2) CHEMICAL DEGRADATION OF THE RO MEMBRANES DUE TO DISINFECTANTS (USUALLY CHLORINE) USED IN THE FEED STREAM. EXTENSIVE PRETREATMENT IS THUS NEEDED WHEN CURRENT RO SYSTEMS ARE USED ON SEAWATER. THUS, ...

THE NAVY HAS A NEED FOR A RELIABLE, COMPACT, AND ENERGY-EFFICIENT COMPRESSED-AIR DEHYDRATION SYSTEM. WE PROPOSE TO DEVELOP SUCH A SYSTEM BASED ON SYNTHETIC MEMBRANE TECHNOLOGY. PRELIMINARY EXPERIMENTAL AND DESIGN STUDIES AT BEND RESEARCH INDICATE THAT IT IS POSSIBLE TO DEVELOP MEMBRANES AND MEMBRANE MODULES DESIGNED SPECIFICALLY FOR THIS APPLICATION--RESULTING IN A SYSTEM THAT CONTAINS ONLY ABOUT ...

THE PRIMARY OBJECTIVES OF THIS RESEARCH PROGRAM IN PHASE I ARE TO DEVELOP CORROSION DATA ON A SERIES OF SIC/AL AND GR/AL METAL MATRIX COMPOSITES. SINCE THESE MATERIALS SHOW SIGNIFICANT POTENTIAL FOR USE IN NAVAL APPLICATIONS, THEIR CORROSION RESISTANCE WILL BE EVALUATED IN DIFFERENT KINDS OF MARINE EXPOSURES. DATA FROM LONGTERM EXPOSURES, SHORT-TERM ACCELERATED ELECTROCHEMICAL TESTS, AND METALLURG ...

A NEW APPROACH TO PHASED ARRAY ANTENNA DESIGN IS PROPOSED, BASED ON UNPUBLISHED WORK AT EMA, WHICH PREDICTS THE POSSIBILITY OF PRODUCING GIGAWATTS OF EFFECTIVE RADIATED POWER. PRELIMINARY PREDICTIONS BASED ON THE NEW DESIGN CONCEPTS INDICATE AS MUCH AS 80 DB INCREASE IN POWER OVER CONVENTIONAL PHASED ARRAY DESIGNS MAY BE ACHIEVABLE. EMA'S CONCEPTS ALLOW ENERGY TO BE STORED ON THE ANTENNA THROUGH A ...

THIS PROGRAM IS ORGANIZAED TO DEMONSTRATE THE FEASIBILITY OF USING A GASEOUS TRITIUM LIGHT SOURCE (GTLS) AS A SELF POWERED DEVICE TO PROVIDE CONTINUOUS ILLUMINATION INSIDE A ROCKET MOTOR ARM-FIRE DEVICE FOR A PERIOD OF 15 YEARS. THE SOURCE WILL ILLUMINATE SAFE/ARMED (S/A) SYMBOLS WITH COLOR CODED LIGHT. AN IMAGE QUALITY FIBER OPTIC BUNDLE WILL ALLOW THE IMAGE OF THE INDICATOR TO BE OBSERVED BY ORD ...

A SIMPLE SAFETY ARMING SWITCH FOR GUIDED MISSILES CAN BE BUILT AROUND AN ACCELEROMETER AND INTEGRATING CIRCUIT. IN GENERAL, DURING THE LAUNCH BOOST PHASE, THE ACCELERATION OF A MISSILE INCREASES TO A MAXIMUM JUST BEFORE BURNOUT. CHARACTERISTIC ACCELERATION PROFILES FOR A PARTICULAR MISSILE ARE DEPENDENT UPON FUEL TAILORING AND MISSION REQUIREMENTS; I.E. AIR-TO-AIR MISSION, GROUND-TO-AIR MISSION, E ...

THIS PROGRAM WILL DETERMINE THE POTENTIAL FOR LIFE IMPROVEMENT, WEIGHT REDUCTION, AND HIGHER LOAD BEARING CAPABILITY OF AIRCRAFT ENGINE COMPONENTS MADE FROM EMERGING MATERIALS AND MANUFACTURING TECHNIQUES. THE GEOMETRIES TO BE STUDIED, BUT NOT LIMITED TO, ARE BOLT HOLES, BLADES, BLADE ATTACHMENTS, CUTOUTS, AND SCALLOPS. TESTING WILL BE CONSTANT AMPLITUDE CRACK GROWTH UNDER BOTH AMBIENT AND HIGH TE ...

THE RESEARCH OUTLINES IN THE PROPOSAL DEALS WITH HIGH BRIGHTNESS, LIQUID ALLOY ION SOURCES (LAIS) THAT CAN BE USED IN MASS SEPARATED FOCUSING COLUMNS TO PROVIDE SUBMICRON FOCUSED BEAMS OF SPECIFIED ION SPECIES. IN PARTICULAR WE PROPOSE TO DEAL WITH THOSE LAIS THAT PROVIDE DOPANT IONS OF AS AND B THAT CAN BE EMPLOYED IN MASKLESS IMPLANTATION OF SILICON BASED IC DEVICES. THE SPECIFIC OBJECT OF THE P ...

ALTHOUGH STRONG IN THE LAMINATE PLANE, COMPOSITES EXHIBIT WEAK INTERLAMINAR PROPERTIES. AS A RESULT, DELAMINATIONS CAN OCCUR DURING MANUFACTURING OR IN SERVICE ENVIRONMENTS. THIS PROPOSAL ADDRESSES A NEED FOR FRACTURE CRITERIA MODELS FOR BOTH ORGANIC AND METAL MATRIX COMPOSITES. A MAJOR OBJECTIVE IS TO ANALYZE AND COMPARE FRACTURES IN MICROSCOPIC AND MACROSCOPIC GEOMETRIES USING A SINGULAR FINITE ...
