THE PROPOSED UNDERSEA MAGNETIC LAUNCHER COULD PROVIDE BENEFIT TO THE NAVY. BUT THE MODERN TORPEDO AND THE AREA ADJACENT TO THE TORPEDO TUBES IS JAMMED WITH DIGITAL ELECTRONICS INCLUDING MICROPROCESSORS. IF THE SHOOTING OFF OF THE TORPEDO SHOULD CAUSE A MEMOR LOCATION TO CHANGE STATE THE MISSION OF THE TORPEDO COULD BE ABORTED, OR IN THE WORST CASE, THE SHIP ITSELF COULD BE PUT IN JEOPARDY. THE DES ...

N/A

USE OF THE PATENTED SPLIT SLEEVE COLD EXPANSION (CX) PROCESS, AND PROCESS VARIATIONS, WILL BE INVESTIGATED AS A MEANS TO EXTEND THE LIFE OF IN-SERIVCE J-52 COMPONENTS DAMAGED BY LOW CYCLE FATIGUE. THESE PROCESSES HAVE BEEN WIDELY USED FOR LIFE EXTENSION OF NEW AND IN-SERVICE AIRFRAME COMPONENTS BUT HAVE NOT BEEN FULLY EVALUATED FOR GAS TURBINE ENGINE APPLICATIONS. THIS PROGRAM WILL DETERMINE THE P ...

PHASE BEHAVIOR STUDIES OF THE HFO(2)/TA(2)O(5) AND HFC/TAC SYSTEMS ARE PROPOSED. THIS WORK EMPHASIZES MEASUREMENT OF LIQUIDOUS TEMPERATURES AND WILL IDENTIFY PHASES PRESENT BETWEEN ABOUT 1500 DEG C AND 2500 DEG C. THE PROPOSAL INCLUDES NOVEL IN SITU METHODS INVOLVING CO(2) LASER HEATING AND THE USE OF ANNEAL QUENCH METHODS. A DIFFUSION COUPLE APPROACH IS PROPOSED AS THE MOST EFFICIENT MEANS OF EVA ...

THE SUCCESSFUL DEVELOPMENT OF HIGH-TEMPERATURE CERAMICS OR CERAMIC COMPOSITES FOR USE IN COMBUSTION ENGINE ENVIRONMENTS WILL REQUIRE DEVELOPMENT OF THERMODYNAMICALLY STABLE OXIDES FOR PROTECTIVE COATINGS OR AS THE MATRIX MATERIAL IN WHISKEROR FIBER-TOUGHENED COMPOSITES. THIS PROGRAM WILL DEVELOP CUBIC FLUORITE RELATED OXIDES (BASED ON Y[2]O[3]) WITH STRUCTURES MODIFIED BY SELECTED DOPING. THE MODI ...

N/A

GEOPHEX, LTD. PROPOSES TO DEVELOP AN AIRBORNE ELECTROMAGNETIC (AEM) SYSTEM DEDICATED TO THE DETECTION OF SUBMARINES IN THE OCEAN (TOPIC NO. N87-22, THE DOD SBIR PROGRAM, 1987). THE AEM METHOD HAS RECENTLY EMERGED AS A VIABLE TECHNIQUE FOR AIRBORNE CHARTING OF WATER DEPTH (IN EXCESS OF PERHAPS 100 M), WATER CONDUCTIVITY (THUS, SALINITY AND TEMPERATURE VARIATIONS), AND BOTTOM SEDIMENT CONDUCTIVITY ( ...

A LOW FREQUENCY, NON-EXPLOSIVE, SOUND SOURCE THAT USES A RADIALLYPOLED, CERAMIC, CYLINDRICAL TRANSDUCER AND OPERATES IN FLEXURAL MODES IS PROPOSED. THE TRANSDUCER IS STRIPED INTO 4 QUADRANTS. ALTERNATE QUADRANTS ARE DRIVEN IN-PHASE AND LOADED INTO THE WATER THEREBY ENHANCING ACOUSTIC PERFORMANCE AT THE LOW FREQUENCY FUNDAMENTAL FLEXURAL MODE. THE TRANSDUCER IS INSTALLED INTO A 3.5 INCH DIAMETER BY ...

N/A

A NOVEL MINIATURIZED MAGNETIC SENSOR IS PROPOSED WHICH OPERATES ON A MOLECULAR LEVEL. RATHER THAN USING A MAGNETIC FIELD TO MODULATE CONDUCTIVITY OR CURRENT FLOW, THE PROPOSED SENSOR MODULATES OPTICAL TRANSMISSION. THE MAGNETIC RESPONSE OF A LIQUID CRYSTALLINE MEDIUM IS GREATLY INCREASED BY THE ADDITION OF CERTAIN SMALL PARTICLES. IN THE LIQUID CRYSTAL MEDIUM THESE PARTICLES SPONTANEOUSLY ALIGN TO ...
