AstroPower proposes to develop gallium phosphide (GaP) ultraviolet (UV) sensors for engine combustion control. The UV spectra from the free radial combustion components correlates with combustion effectivity in terms of predetonation, and provides a real time basis for central control of excess air ratio, internal combustion temperatures, and other fuel injector parameters. A system for the engine ...

Computer and engine studies demonstrated a 100% increase in diesel engine power with the use of 31% oxygen enriched air (OEA) versus standard 21% oxygen air. Additional benefits from OEA include: (1) improved fuel efficiency, (2) compatible with lower grade (volatility) fuels, (3) reduced CO and hydrocarbon emissions, (4) enhanced lean burn capability, (5) smoother less noisy operation, (6) better ...

NONDESTRUCTIVE INSPECTION FOR CORROSION IN ALUMINUM AIRCRAFT STRUCTURES OF AGING AIRPLANES HAS BEEN DEMONSTRATED RECENTLY USING MAGNETO-OPTIC/EDDY CURRENT IMAGING TECHNOLOGY. THIS TECHNOLOGY WAS DEVELOPED FOR RAPID INSPECTION OF SURFACE BREAKING CRACKS NEAR RIVETS IN ALUMINUM AIRCRAFT ALLOYS, BUT HAS BEEN SHOWN TO BE CAPABLE OF GENERATING IMAGES OF CORRODED REGIONS AS WELL. DEVELOPMENT OF A CORROS ...

The long term objective of this program is to provide a high performance, thin-film microbattery that will serve as a highly reliable, rugged, miniature power source amenable to providing on-chip power for microelectronic devices. A solid state lithium-based technology will be adapted to this product. In Phase I, the project will further investigate candidate microbattery applications, develop app ...

Bubbles within a cloud can undergo collective oscillations and produce large acoustic emissions at low frequencies (20 to 2 kHz). Using the collective oscillation properties, relatively small targets can be developed for underwater acoustics research and other applications. This proposal presents three designs to produce and contain bubble clouds in a fixed geometry for the purpose of producing lo ...

QUEST Integrated, Inc. (formerly Flow Research) proposes to develop and fabricate compliant coatings synthesizing dolphin skin/blubber for use on underwater vehicles to achieve drag and flow noise reduction. Guided by the theory of the hydrodynamic response of viscoelastic materials, the design of the compliant coatings will be aided by using a computer code combining finite element techniques, vi ...

PAVEMENT DISTRESS DATA ARE UTILIZED DURING PAVEMENT EVALUATION, DESIGN, REHABILITATION, MAINTENANCE, MANAGEMENT, AND RESEARCH. CURRENTLY, THE MANUAL SURVEY METHOD, UTILIZING PAPER AND PENCIL, IS USED EXTENSIVELY IN COLLECTING THE DISTRESS DATA, BUT THIS PROCESS IS SLOW, TEDIOUS, EXPENSIVE, AND PRONE TO HUMAN ERROR. THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP A COMPUTERIZED PAVEMENT DISTRESS DATA ...
