THERE EXISTS A NEED FOR INEXPENSIVE, LOW FREQUENCY (0.001 HZ TO 50 HZ) ULTRASENSITIVE VIBRATION DETECTORS. RUGGEDNESS, STABILITY, DYNAMIC RANGE, SENSITIVITY AND COST ALL COMBINE TO LIMIT IN ONE WAY OR ANOTHER THE USE OF CONVENTIONAL DEVICES. RECENT RESEARCH WITH THE NEW CLASS OF HIGH TEMPERATURE CERAMIC SUPERCONDUCTORS AND WITH EDDY CURRENT DISPLACEMENT GAUGES HAS PROVIDED A NEW APPROACH TO THESE ...

MOST OF THE ULTRASONIC SCANNING SYSTEMS IN SERVICE OR BEING INSTALLED AT DOD FACILITIES OFFER SOME MEANS OF RECORDING INSPECTION DATA. HOWEVER, THE ADVANTAGES OF THIS CAPABILITY AREN'T BEING FULLY REALIZED BECAUSE THE STORAGE MEDIA AND DATA ARCHIVAL FORMATS DIFFER FROM SYSTEM TO SYSTEM. THIS LACK OF STANDARDIZATION IS CAUSING A PROBLEM THAT IS BECOMING WIDESPREAD AS MORE AND MORE DOD FACILITIES IN ...

THIS PROPOSED WORK WILL EVALUATE THE USE OF ULTRA-HIGH PRESSURE (20,000 TO 55,000 PSI) WATERJETS AS A METHOD OF REMOVING COATINGS FROM SHIP'S HULL SYSTEMS. ULTRA-HIGH PRESSURE (UHP) WATERJETS ARE IN DAILY COMMERCIAL USE FOR NUMEROUS CLEANING AND COATING REMOVAL TASKS. THE ADVANTAGES OF UHP WATER INCLUDE: IMPROVE PRODUCTIVITY; LOWER REACTION THRUST RESULTING IN INCREASED OPERATOR SAFETY; ABILITY TO ...

PHASE I OBJECTIVES ARE TO DEVELOP THE CONCEPTUAL DESIGN OF A ROLLER BEARING MEASUREMENT SYSTEM AND TO DEMONSTRATE ITS FEASIBILITY. THEN, APPROPRIATE MEASURING TECHNIQUES FOR THE VARIOUS PARAMETERS WILL BE IDENTIFIED. CANDIDATE MEASURING TECHNIQUES WILL INCLUDE HETERODYNE INTERFEROMETERS, EDDY CURRENT SENSORS, OPTICAL TRIANGULATION SENSORS, MOIRE DEFLECTOMETRY, AND LASER MICROMETERS. THE CRITICAL T ...

THIS PROPOSAL PROPOSES TO INVESTIGATE THE FEASIBILITY OF DEVELOPING A RAPID DEPLOYMENT CAPABILITY FOR TACTICAL COMBAT MODELS. THE CAPABILITY IS NECESSARY TO SUPPORT SAMPLING OF ALTERNATIVE SIMULATED TACTICAL DEPLOYMENTS (STDS), WHICH IS PRESENTLY NOT FEASIBLE TO DO ON A SCALE AND LEVEL OF DETAIL REQUIRED BY EXISTING LARGE-SCALE (THEATER LEVEL OR CORPS LEVEL) TACTICAL COMBAT MODELS. WITHOUT THIS CA ...

THIS PROJECT WILL INVESTIGATE AND DEMONSTRATE THE CAPABILITY OF BIDIRECTIONAL REFLECTANCE DISTRIBUTION FUNCTIONS TO CHARACTERIZE THE REPLICATION ATTRIBUTES OF DECOYS, ALLOWING SPECIFICATION AND TOLERANCES TO BE DEVELOPED. THIS WILL BE PERFORMED BY A LITERATURE SEARCH, MATHEMATICAL ANALYSIS AND HUMAN SUBJECT TESTING. A GONIOREFLECTOMETER WILL BE DESIGNED AND BREADBOARDED TO INDICATE THE CAPABILITY ...

ELECTROIMPACT PROPOSES THAT ELECTROMAGNETIC LAUNCH BE EMPLOYED WITH A PERMANENT MAGNET PUSHER MOTOR AND A TRAVELING WAVE LAUNCH TUBE. NEODYMIUM-IRON-BORON PERMANENT MAGNETS ELIMINATE THE REQUIREMENT FOR HIGH POWER ELECTRICAL CONNECTIONS TO THE MOVING LAUNCHING DEVICE. MAGNETIC SUSPENSION TECHNOLOGY USING PERMANENT MAGNETS WILL PREVENT THEDEVICE FROM RATTLING DOWN THE LAUNCH TUBE. A PERMANENT MAGNE ...

A STUDY OF THE USE OF A MULTI-STAGE SOUNDING ROCKET AS A LOW COST ALTERNATE LAUNCH SYSTEM FOR FLIGHT TESTING OF SMALL REENTRY VEHICLES AT THE KWAJALEIN MISSILE RANGE (KMR) WILL BE PERFORMED. A COMBINATION OF GUIDED AND UNGUIDED STAGES IS CONTEMPLATED. A RELATIVELY LOW-COST, HIGH-PERFORMANCE SOLID MOTOR IS REQUIRED FOR THE FINAL VELOCITY STAGE. SELECTION OF A LAUNCH SITE IN THE NEAR VICINITY OF KMR ...
