AN INTEGRATED DRILL-LOAD-SHOT (IDLS) SYSTEM WILL BE DEVELOPED TO OVERCOME THE CURRENT DISADVANTAGES AND REALIZE THE POTENTIAL OF EXPLOSIVE EXCAVATION SYSTEMS. THE IDLS SYSTEM IS TEAMED WITH A UNIQUE SPIRAL DRILL AND BLAST CONCEPT, THE COMBINATION OF WHICH PERMITS NEARLY CONTINUOUS, RATHER THAN CYCLIC OPERATION. THIS CONCEPT PROVIDES A SIMPLE, REPETITIVE BLAST GEOMETRY, EFFICIENT BLASTING TO A FREE ...

COMPOSITE LAMINATES MADE FROM CONVENTIONAL EPOXY PREPREGS ARE PRONE TO DELAMINATION DUE TO IMPACT OR EDGE EFFECTS. SOME MEANS OF IMPROVING COMPRESSIVE STRENGTH AFTER IMPACT IS DESIRED. STITCHING IS ONE OPTION, BUT CAUSES DAMAGE TO IN-PLANE PROPERTIES (STRENGTH, MODULUS). THE PROPOSED TECHNIQUE UTILIZES STAPLES TO CONTROL DELAMINATION. DAMAGE TO IN-PLANE PROPERTIES WILL BE MINIMIZED BY VIBRATION OF ...

HIGH PERFORMANCE ELECTRONIC CIRCUITS ARE EXCEEDING THE LIMITS OF EXISTING PACKAGING MATERIALS. RECENT DEVELOPMENTS IN SURFACE MOUNTING LEADLESS CHIPS, MULTI-LAYER CONSTRUCTION, AND HIGH SPEED DENSITY PACKED CIRCUITS DEMAND INNOVATIVE NEW MATERIALS. THE OBJECTIVE OF THIS PROGRAM TO DETERMINE THE FEASIBILITY OF NEW MATERIALS. PBT (POLYBENZTHIAZOLE) ORDERED POLYMER FILMS AS A SUBSTRATE MATERIAL IN AD ...

ENHANCED EGRESS REQUIREMENTS NECESSITATES A RATE OF ADVANCE OF 80 FT/HR FOR BOTH A BORING MACHINE AND GROUND SUPPORT LINING SYSTEM. THIS ADVANCE RATE IS BEYOND THE CURRENT TECHNICAL FEASIBILITY OF ALL STATE-OF-THE-ART LINING SYSTEMS. AN INNOVATIVE PRESSURIZED LINING SYSTEM USING A POLYMERIC MATERIAL IS PRESENTED WHICH WILL MEET BOTH THE STRUCTURAL, AS WELL AS, OPERATIONAL REQUIREMENTS OF THE EGRES ...

THE PROPOSED WORK WILL INVOLVE EVALUATION OF ORDERED POLYMER SHEET AND TAPE-REINFORCED COMPOSITE STRUCTURES FOR APPLICATIONS SUCH AS ROCKET MOTOR CASES, PRESSURE VESSELS AND OTHER CYLINDRICAL COMPONENTS. THE OBJECTIVE OF THE PROGRAM IS TO MAKE HIGH QUALITY FILM LAMINATES USING A FABRICATION PROCESS AMENABLE TO SCALE-UP. TEST SAMPLES WILL BE MADE, TESTED AND COMPARED WITH OTHER HIGHER PERFORMANCE C ...

MOBILE ROBOTS REQUIRE CONSIDERABLE AMOUNTS OF POWER TO PERFORM WORK, PROVIDE LOCOMOTION, AND RUN THE CONTROL ELECTRONICS. ARTIFICIAL INTELLIGENCE AND VISION PROMISE TO MAKE FUTURE MOBILE ROBOTS HIGHLY AUTONOMOUS AND THEY WILL BE EXPECTED TO OPERATE OVER SUBSTANTIAL DISTANCES FOR LONG PERIODS OF TIME. THE NEED FOR LIGHTWEIGHT, STABLE, POWERFUL ENERGY SOURCES THAT WITHSTAND TEMPERATURE EXTREMES, SHO ...

THE ARMOR PLATES USED IN TESTING MUNITIONS CONTAINING DEPLETED URANIUM (DU) ARE SUBJECT TO DISPOSAL AS LOW-LEVEL RADIOACTIVE WASTE. THE OBJECTIVE OF THIS PROPOSAL IS TO DEVELOP SELECTIVE SOLVENTS THAT WILL PREFERENTIALLY ATTACK THE CONTAMINATED AREAS OF THE TARGET, REMOVING THE DU, AND LEAVING THE ARMOR PLATE UNAFFECTED AND INTACT. PREVIOUS WORK HAS BEEN DONE ON THE DISSOLUTION OF URANIUM FOR ANAL ...

THE OBJECTIVE OF THIS PROGRAM IS TO DEMONSTRATE THE FEASIBILITY OF REMOTE MONITORING OF HUMAN CORE TEMPERATURE WITHOUT ANY PHYSICAL LINK WITH THE TEST SUBJECT. TEMPERATURE SENSING WILL BE CARRIED OUT BY AN INDUCTIVELY-COUPLED, INGESTED RADIOCAPSULE. IN PHASE I, AN EXISTING RADIOCAPSULE SYSTEM WILL BE UPGRADED AND ADAPTED TO MEET ARMY REQUIREMENTS. THIS UPGRADED SYSTEM WILL INCLUDE A RADIOCAPSULE, ...

THE ECONOMIC USEFULNESS AND THE RANGE OF INFOMATION THAT CANBE OBTAINED FORM ON-LINE INFRARED GAS ANALYSIS IS LIMITED SINCE A COMPLEX AND UNRELIABLE EXTRACTIVE SAMPLING SYSTEM ORA DEDICATED SPECTROMETER IS NEEDED AT EACH SENSING POINT IN THE PROCESS. THIS PROGRAM INTENDS TO DEMOSTRATE THE FEASIBILITY OF TRANSMITTING THE IR SPECTRAL INFORMATION VIA OPTICAL FIBERS DRAWN FROM NEW MATERIALS--HEAVY MET ...

MEMBRANE APPLICATIONS FOR GAS CLEANUP AND GAS SEPARATION HAVE BEEN LIMITED BECAUSE OF THEIR LOW FLUX, THE CHEMICAL RESISTANCE OF CURRENT MATERIALS, AND BECAUSE OF THEIR HIGH TEMPERATURE LIMITS. MEMBRANE PERMEATION RATE IS A FUNCTION OF THE CHEMICAL POTENTIAL DIFFERENCE ACROSS THE MEMBRANE ANDTHE PATH LENGTH. CORROSIVE MATERIALS SUCH AS FLUE EMISSIONS, SYNTHESIS GAS, AND HYDROGEN SULFIDE CREATE DIF ...
