ELECTRONIC COMPONENTS AND SYSTEMS FOR USE IN DEFENSE APPLICATIONS HAVE REQUIREMENTS OF MATERIAL UNIFORMITY, QUALITY ELECTRICAL CONNECTIONS, MICROSTRUCTURAL INTEGRITY AND FREEDOM FROM STRESS AND DEFECTS. ALTHOUGH THE ELECTRONICS INDUSTRY HAS BEEN SUCCESSFUL IN MEETING MANY OF THESE CONDITIONS, THE INCREASING DEMANDS FOR HIGHER SPEED DEVICES AND CIRCUITS ARE STEADILY REDUCING THE MARGINS OF SAFETY. ...

THERE IS A NEED FOR SMALL, COMPACT, AND RUGGED SOURCES THAT OPERATE IN THE 0.7-2MM WAVELENGTH REGION. SUCH A SOURCE WOULD BE SOLID STATE BUT THE OVERALL SYSTEM WILL MOSTLIKELY NOT BE SO COMPACT IF THE WIDEBAND FREQUENCY TUNABILITY IS DESIRED. THE CONCEPTUAL SOLID-STATE (IN-AS) GYROTRON IS WIDE-BAND BUT OPERATED WITH A CRYOGENIC SYSTEM WHICH IS MOSTLIKELY BULKY. THIS PROPOSAL ADDRESSES CURRENT AVAI ...

A MICROCLIMATOLOGICAL WEATHER STATION DESIGN IS PROPOSED WHICH INCORPORATES RESEARCH QUALITY INSTRUMENTS CAPABLE OF MEASURING HEAT FLUXES DIRECTLY. RECENT TECHNOLOGICAL ADVANCES HAVE ENABLED THESE INSTRUMENTS TO OPERATE IN REMOTE, LOW POWER, UNATTENDED APPLICATIONS. ULTRASONIC TECHNOLOGY IS USED TO MEASURE SENSIBLE AND LATENT HEAT FLUXES USING THE EDDY CORRELATION METHOD. THE WEATHER STATION IS DE ...

THE PRIMARY OBJECTIVE OF THIS RESEARCH IS TO DEVELOP A METHOD THAT WILL IMPROVE BOTH THE RELIABILITY AND PREDICTABILITY OF WELDING AGE HARDENING ALUMINUM ALLOYS. THIS MAY BE ACCOMPLISHED BY USING AN IMPROVED VASR (VIBRATORY AGING AND STRESS RELIEF) SYSTEM, SQUARE WAVE PULSED ARC WELDING, AND POSSIBLY A COMBINATION OF BOTH TECHNIQUES. VASR TECHNIQUES INCLUDE TESTING IN BOTH THE SUBRESONANT AND RESO ...

CONTRACTOR WILL DEVELOP A LAGRANGIAN FORMULATION FOR THE ELECTROMAGNETIC RESPONSE OF A METALLIC ENCLOSURE WITH THIN, SLIGHTLY DIFFUSIVE WALLS AND A WIRE SPANNING THE ENCLOSURE. CONTRACTOR WILL FIRST DERIVE A LAGRANGIAN OPERATOR ON THE FIELDS WHICH IS STATIONARY WHEN MAXWELL'S EQUATIONS ARE SATISFIED. THE LAGRANGIAN WILL THEN BE USED TO DETERMINE THE ENCLOSURE EIGENMODES (WIRE INCLUDED) AND THE AMP ...

CODES CURRENTLY EXIST THAT WILL CALCULATE THE ELECTROMAGNETIC ENVIRONMENT (EMP) PRODUCED BY A BEAM OF COLLIMATED GAMMA RAYS. THE COLLIMATION MAY BE EITHER CYLINDRICAL OR CONICAL. THE CURRENT EFFORT WILL BE TO INSTALL THE CODES ON AN ARMY CRAY COMPUTER AND TO SET THEM UP AND RUN THEM FOR PROBLEMS OF INTEREST TO THE ARMY.

THERE IS AN ESTABLISHED NEED FOR A SIMPLE ROBUST TRANSDUCER TO MEASURE PARTICLE VELOCITY IN SEVERE BLAST AND SHOCK ENVIRONMENTS SUCH AS NUCLEAR AND HIGH EXPLOSIVE TESTS. A GAGE CONCEPT IS PROPOSED FOR DEVELOPMENT, BASED ON THE PROVEN MEASUREMENT PRINCIPLES USED IN THE HIGHLY SUCCESSFUL DX GAGE, BUT RECONFIGURED MECHANICALLY AND ELECTRICALLY TO WITHSTAND THE HARSH SHOCK ENVIRONMENTS. THE CONCEPT RE ...

A RESEARCH EFFORT COMPLETED RECENTLY FOR THE AIR FORCE IDENTIFIED NEW TECHNOLOGIES FOR ANGULAR MOTION MEASUREMENT. TWO CONCEPTS WERE FOUND WHICH APPEAR TO OFFER POTENTIAL FOR AN EXCELLENT COMBINATION OF SMALL SIZE, WIDE DYNAMIC RANGE, WIDE BANDWIDTH AND EASE OF FABRICATION AND UTILIZATION. ONE DEVICE, CALLED A FLUID-FILLED BENDER BEAM, USES PIEZOCERAMICELEMENTS TO PRODUCE A SIGNAL PROPORTIONAL TO ...

AS ARMY MEDICAL FIELD AND HOSPITAL EQUIPMENT, THROUGH TECHNOLOGICAL ADVANCES IN INTEGRATED HARDWARE, BECOMES MORE COMPLEX AND SOPHISTICATED, IT LIKEWISE BECOMES MORE SUSCEPTIBLE TO DAMAGE FROM POTENTIAL NUCLEAR EMP COUPLED CURRENT AND VOLTAGE TRANSIENTS. THIS PROPOSAL DEFINES A PLAN WHEREBY THE DESIGNATED MISSION ESSENTIAL MEDICAL EQUIPMENT MAY BE ANALYZED AND EVALUATED FOR TECHNIQUES TO ACHIEVE H ...
