SOLAR CELLS ARE BEING FABRICATED USING THIN FILMS OF SILICON ON INEXPENSIVE, FLEXIBLE CLOTH SUBSTRATES. PHOTOVOLTAIC DEVICES FABRICATED WITH THESE STRUCTURES CAN DEMONSTRATE THE HIGH PERFORMANCE OF CRYSTALLINE SILICON WITH THE LIGHT WEIGHT OF THIN FILM SOLAR CELLS. THE RESULT IS A SOLAR CELL THAT HAS APPLICATIONS WHEREVER A LIGHTWEIGHT POWER SOURCE IS NEEDED. THE RADIATION TOLERANCE OF THIN CRYSTA ...

THIS DOCUMENT IS AN SBIR TECHNICAL PROPOSAL SUBMITTED TO THEFEDERAL AVIATION ADMINISTRATION BY DELTA INFORMATION SYSTEMS, INC. IN RESPONSE TO SBIR SOLICITATION NUMBER 91-FA11. THE PURPOSE OF THE PROPOSED PROGRAM IS TO INVESTIGATE, ANALYZE, AND DESIGN ALTERNATIVE DATA COMPRESSION SYSTEMS TO EFFICIENTLY TRANSMIT AIR TRAFFIC CONTROL DISPLAY DATA FROM MAJOR AIRPORTS TO SMALLER SATELLITE AIRPORTS ON LI ...

EVAPORATING A COOLANT FROM THE SURFACES OF A FINE POROUS WICK CAN DO SOMETHING NO OTHER KNOWN COOLING SCHEME CAN DO: MAINTAIN A NEARLY CONSTANT SURFACE TEMPERATURE WHILE THE HEAT FLUX IS VARIED BY TEN TIMES OR MORE. THE PROGRAM GOAL IS TO COOL HIGH-POWERED LASER MIRRORS, AND OTHER TOUGH COOLING PROBLEMS. THE UNIQUE HEAT EXCHANGER DESIGN IS AN ADVANCED COUSIN OF THE HEAT PIPE AND OF PUMPED TWO-PHAS ...

The objective of this effort is to develop high performance rare earth permanent magnets with essentially constant magnet properties over a wide temperature range of -50 to 350oC, and which can survive temperatures as high as 500oC, for TWT applications.The combination of a light rare earth (Sm) with heavy rare earths (Gd, Er, and Ho) provides very low temperature coefficients of magnetic properti ...

kTC's high performance thermal core technology offers the potential of significant cost savings by allowing the use of low cost commercial components without the need for liquid flow through thermal cores. kTC's encapsulated APG thermal core is a highconductivity (>1000WmL) macrocomposite comprised of annealed pyrolytic graphite (AG) encapsulated within an aluminum sheet. In Phase I, k Technolog ...

MRi proposes to further the demonstration of graphite foam heat exchanger fabrication technology utilizing its innovative active solder joining alloys and processes (S-Bond). The proposed Phase II will build on the success of the Phase I feasibilitystudies that showed the active solder joined Gr-foam core heat exchangers to have over 15 x the heat transfer capacity as aluminum finned heat exchang ...

The sensing element is the heart of a sensor. A generic requirement for any sensor is that it only responds to the particular stimulus since all other stimuli are considered noise. The basic physics of the operation of a sensor thus determines the limitof its sensitivity. Here we build upon a family of proposed light sensors in which sensor noise is substantially reduced by altering the nature ...

Stress monitoring in composite materials is a difficult but necessary endeavor. It is required for testing to compare measurements with modeling predictions as well as to monitor flexing and vibration under load. Presently, there are only a limitednumber f methods to measure strains that are suitable for embedding in a composite material and all are either expensive or complex. This proposal is ...

Intense dynamic and thermal loads will occur during stage-separation events that are of major concern from both operational and safety viewpoints. The insensitive-munitions (IM) stimuli and thermal/dynamic response associated with such events has received very little attention, yet this is of major concern for the KEI vehicle undergoing Stage 1 to Stage 2 separation. The KEI event is at lower alti ...
