IRON-BASED RARE EARTH-BORON PERMANENT MAGNETS OF THE COMPOSITION FE14ND2B WHICH WERE DISCOVERED SEVERAL YEARS AGO POSSESS MAGNETIC ENERGY PRODUCTS EXCEEDING 40 MGOE. THE OPPORTUNITY EXISTS TO DESIGN ASYNCHRONOUS MOTOR WITH SUCH PERMANENT MAGNET MATERIALS. SINCE THE WEIGHT OF A MOTOR IS INVERSELY PROPORTIONAL TO THE ENERGY PRODUCT OF THE MAGNET, IT IS CLEAR THAT MOTORS DESIGNED FROM SUCH HIGH ENERG ...

RECHARGEABLE POWER SOURCES POSSESSING HIGH ENERGY DENSITIES, BRIEF BUTREPETITIVE HIGH CURRENT OUTPUTS, AND THOUSANDS OF DUTY CYCLES ARE REQUIRED FOR STRATEGIC DEFENSE SYSTEMS. TO ADDRESS THESE NEEDS, HIGH SURFACE AREA, THIN FILM CATHODES ARE BEING FABRICATED FOR AMBIENT TEMPERATURE LITHIUM BATTERIES. THESE CATHODES FEATURE AN ARRAY OF APPROXIMATELY L MICROMETER MICROCRYSTALLITE TIS2 PLATES ORIENTE ...

A SYSTEMATIC MEANS IS BEING DEVELOPED TO RELIABLY DEPOSIT OPTICAL-AND/OR TRIBOLOGICAL-QUALITY DIAMOND THIN FILMS ON SUBSTRATES RELEVANT TO STRATEGIC DEFENSE NEEDS. TO ACHIEVE THIS OBJECTIVE, THE CONDITIONS OF THIN FILM DIAMOND SYNTHESIS BY ELECTRON-ASSISTED PLASMA-ENHANCED CHEMICAL VAPOR DEPOSITS ARE BEING CORRELATED WITH THE RESULTING AS-DEPOSITED MICROSTRUCTURE (GRAIN SIZE AND ORIENTATION). CORR ...

A PROGRAM TO DEVELOP ELECTROCHROMIC DEVICES CAPABLE OF FAST TRANSMISSIVE TO REFLECTIVE OPTICAL SWITCHING IS PROPOSED. THESE DEVICES WOULD BE USED FOR OPTICAL HARDENING IN THE WAVELENGTH RANGE FROM 0.615 MICROMWTERS. OPTICAL SWITCHING ELEMENTS BASED ON SINGLE CRYSTAL LAYERS OR EPITAXIAL FILMS OF THE METAL DICHALOCOGENIDES ZRS(2) AND HF(2) WOULD BE DEVELOPED. WE PROPOSE TO INTERCALATE SINGLE CRYSTAL ...

HIGH SPECIFIC IMPULSE ELECTRIC PROPULSION CONCEPTS WILL BE INVESTIGATED FOR OPERATION IN THE 0.1-5 MW POWER RANGE TO SUBSTANTIALLY REDUCE PROPELLANT MASS REQUIREMENTS AND SUBSEQUENT COST, OVER CHEMICAL PROPULSION, FOR ORBIT TRANSFER FROM LOW EARTH ORBIT, STATION KEEPING AND SUBTLE EVASIVE MANEUVERING OF SDI PAYLOADS. A DATA BASE DOCUMENTING DIFFERENT ELECTRIC PROPULSION CONCEPTS WILL BE DEVELOPED ...

PRESENT ION ENGINE TECHNOLOGY IS LIMITED IN ENGINE THRUST DENSITY AND EFFICIENCY BY ENERGY EXPENSIVE PLASMA PRODUCTION PROCESSES AND BY ION ACCELERATOR SYSTEM DESIGNS WHICH LIMIT THE ATTAINABLE BEAM CURRENT DENSITY. IN ADDITION, NO EFFORTS HAVE BEEN MADE TO ENHANCE THE BASIC LOW OPERATING TEMPERATURE POTENTIAL OF THE ENGINE CONCEPT TO CREATE ANENGINE DESIGN WITH LITTLE OR NO INFRARED SIGNATURE. CO ...

THIS PROJECT WILL INVESTIGATE A NEW STRUCTURAL MATERIAL THAT APPEARS TO HAVE A NOVEL COMBINATION OF PROPERTIES SUITED TO LAUNCH VEHICLE APPLICATIONS. IN ADDITION, INITIAL WORK WITH THE MATERIAL INDICATES THAT IT SHOULD LEND ITSELF TO LOW-COST FABRICATION TECHNIQUES. WE WILL FIRST CHARACTERIZE THE MATERIAL ITSELF, WITH THE AIM OF IDENTIFYING IDIOSYNCRASIES THAT MAY LIMIT ITS RANGE OF APPLICATION. N ...

IN ADVANCED INFRARED FOCAL PLANE ARRAYS (IR FPAS), AS THE NUMBER OF DETECTORS ON THE ARRAY INCREASE AND THE COMPLEXITY OF TARGET DETECTIONBECOMES GREATER, THERE IS AN ASTRONOMICAL INCREASE IN SIGNAL PROCESSING NECESSARY TO RESOLVE AND DISCRIMINATE TARGETS SATISFACTORILY. PRE-PROCESSING ON THE FOCAL PLANE TO THE GREATEST EXTENT POSSIBLE IS THEREFORE DESIRABLE, ALTHOUGH IT HAS BEEN LIMITED BY POWER ...

THE DESIGN OF AN EXO-ATMOSPHERIC PROJECTILE SEEKER REQUIRES THE CAPABILITY TO DETECT AND TRACK TARGETS AGAINST THE BACKGROUND, PARTICULARLY, THE EARTH BACKGROUND RAPIDLY MOVING BEHIND THE TARGET AND PRODUCING A FALSE SIGNAL MASKING THE SLOWLY MOVING TARGET. CURRENT SENSOR TECHNOLOGY HAS NOT BEEN ABLE TO SOLVE THIS PROBLEM. A LIGHTWEIGHT EXO-ATMOSPHERIC PROJECTILE SEEKER APPROACH CAPABLE OF EXTRACT ...

RESEARCH IS DIRECTED AT TECHNIQUES TO IMPROVE SURFACE MORPHOLOGY IN SILICON ON INSULATOR (SOI) WAFERS PREPARED BY ZONE MELTING RECRYSTALLIZATION (ZMR). THE THREE AREAS OF PRIMARY IMPORTANCE IN IMPROVING THE SURFACE MORPHOLOGY OF ZMR PROCESSED WAFERS ARE: SLIP, BOW AND WARP, AND SURFACE SMOOTHNESS. SLIP IS CAUSED BY THERMALLY INDUCED STRESS THAT RESULTS FROM THE TEMPERATURE GRADIENT IN THE MELT ZON ...
