TO DEFINE, DESIGN, AND BUILD PROTOTYPE HARDWARE AND SOFTWARE TO ENABLE A PILOT OR GUNNER TO USE HUMAN VOICE TO RECEIVE AUTOMATIC STATUS REPORTS, GIVE COMMANDS TO, AND QUERY ARMAMENT, AIRCRAFT, AND FLIGHT INSTRUMENT FUNCTIONS. HARDWARE WILL BE CONSTRUCTED ON A MODULAR BASIS CONSISTING OF A SPEECH OUTPUT ADVISOR AND A LOW MEMORY REQUIREMENT (LMR) VOICE/UTTERANCE RECOGNIZER. THE LMR VOICE/UTTERANCERE ...

OPTOELECTRONIC SOURCES, INTEGRATED AS MONOLITHIC ELEMENTS ON SILICON VLSI CHIPS, OFFER IMPORTANT ADVANTAGES IN THE TRANSMISSION OF INFORMATION WITHIN THE CHIP OR BETWEEN CHIPS IN ADVANCED COMPUTER SYSTEMS. THE SPEED OF OPTICAL-INTEGRATED VLSI DEVICES IS EXPECTED TO BE CONSIDERABLY HIGHER THAN EQUIVALENT VLSI WITH METALLIC INTERCONNECTS, DUE TO ABSENCE OF THE RC DELAY INHERENT IN THE METALLIC CONDU ...

THE ULTIMATE HIGH-EFFICIENCY CRYSTALLINE SILICON SOLAR CELL DESIGN CONSISTS OF A THIN FILM OF ELECTRICALLY-ACTIVE SILICON EPITAXIALLY GROWN ON AN OXIDE-OVERCOATED, INFRARED-TRANSPARENT GALLIUM PHOSPHIDE (GAP) SUBSTRATE. IN ADDITION TO HIGH CONVERSION EFFICIENCY AND INTRINSIC RADIATION RESISTANCE DUE TO THE THIN ACTIVE LAYERS, THIS NOVEL DESIGN HAS SEVERAL UNIQUE PERFORMANCE ENHANCING FEATURES. THE ...

A DEFINITION OF THE INFLUENCE OF HEATING RATE ON THE MECHANICAL AND THERMAL PROPERTIES OF PHENOLIC COMPOSITES USED IN ROCKET MOTOR COMPONENTS IS REQUIRED. IN ORDER TO ACCOMPLISH THIS GOAL, IT IS NECESSARY TO FIRST DEFINE THE INDEPTH TIME-TEMPERATURE RESPONSE OF THESE PHENOLIC COMPONENTS SUBJECTED TO THE MOTOR ENVIRONMENT. ONCE THIS HAS BEEN ACCOMPLISHED, THE VARIOUS TECHNIQUES WHICH HAVE BEEN USED ...

CARBON/CARBON COMPOSITES ARE HIGH STRENGTH MATERIALS WHICH WILL BE INCREASINGLY USED IN ADVANCED AEROSPACE AND DEFENSE SYSTEMS. AS MATERIAL PERFORMANCE REQUIREMENTS BECOME MORE STRINGENT, THE CURRENT PROCESS CONTROL METHODS WILL BECOME INADEQUATE AND MANUFACTURING VARIABILITIES WILL IMPACT ON SYSTEM PERFORMANCE, COST AND RELIABILITY.CURRENT MANUFACTURING SYSTEMS RELY HEAVILY ON TEMPERATURE AND PRE ...

CARBON-CARBON COMPOSITES ARE ATTRACTIVE MATERIALS FOR HIGH TEMPERATURE APPLICATIONS BECAUSE THEY ARE LIGHTWEIGHT AND RETAIN STRENGTH AT HIGH TEMPERATURES. HOWEVER, THESE COMPOSITES BECOME SEVERELY OXIDIZED ABOVE 700 DEG F IN AIR OR AN OXIDIZING ENVIRONMENT. PREVIOUS RESEARCH AT FMI INDICATES THAT CERAMIC MATRICES CAN BE INTRODUCED INTO A FIBROUS PREFORM USING SIMILAR PROCESSING TECHNOLOGY TO CARBO ...

MECHANISMS EXIST IN NATURE CAPABLE OF ACCELERATING JETS OF MATTER TO VELOCITIES CLOSE TO THAT OF LIGHT, WITH GREAT ENERGY EFFICIENCY. THESE MECHANISMS ARE NOT PRESENTLY UNDERSTOOD, BUT ARE OBSERVED TO OCCUR BOTH IN THE CENTRAL REGIONS OF GALAXIES AND IN A FEW STARS IN OUR OWN GALAXY. THE EXISTANCE OF ASTROPHYSICAL JETS ON THESE TWO VERY DIFFERENT SCALES SUGGESTS THAT SOME COMMON MECHNISM MAY EXIST ...
