The objective of this effort is to demonstrate a prototype advanced diagnostic system for the T800 turboshaft engine using a hybrid polynomial network and production-rule expert system. The resulting system will demonstrate the feasibility of developing a revolutionary diagnostic capability which can model the engine at a system level, detect failures before they become signficant isolate faults, ...

CURRENTLY, AIRBREATHING PROPULSION SYSTEMS WHICH OPERATE IN THE HIGH SUBSONIC REGIME ARE EXPENSIVE, COMPLEX, HEAVY AND USE PERISHABLE FUELS. TO OVERCOME THESE LIMITATIONS, A NOVEL PROPULSION CONCEPT BASED ON A PULSE DETONATION ENGINE (PDE) OR A CONVENTIONAL RAMJET COMBUSTOR (CRC) COUPLED WITH A BORON SOLID FUELED HYBRID GAS GENERATOR (HGG) IS PROPOSED. THE INNOVATION DRAWS FROM RECENT SUCCESSES IN ...

Adroit Systems, Inc. proposes to develop a hand-held , autonomous Satellite Location and Point System (SLAPS). The system will store communication satellites' ephemeris data to calculate and display visibility windows. SLAPS also will use this data to calculate the azimuth and elevation angle to the communication satellite of interest. The system will use interferometry of Global Positioning Syste ...

ASI proposes developing a novel MultiNetwork Engineering Tool which is innovative in its unique integration of several state-of-the-art technologies with established technologies. The state-of-the-art technologies include unique network data visualization algorithms, a data driven intelligent equipment database, novel network modeling tools based on graph theory algorithms, network planning heuris ...

THE NEXT GENERATION OF HIGH POWER, HIGH FREQUENCY ELECTRONIC DEVICE TECHNOLOGY WILL BE BASED ON WIDE BANDGAP SEMICONDUCTOR MATERIALS SUCH AS SIC, GAN AND DIAMOND. OF THESE, SILICON CARBIDE IS THE MOST PROMISING MATERIAL FOR NEAR TERM APPLICATIONS, SINCE ITS PROCESSING SHARES MANY COMMON FEATURES WITH WELL-ESTABLISHED SILICON PROCESSING. TECHNOLOGY HAS BEEN DEMONSTRATED FOR PRODUCING OHMIC AND SCHO ...

HIGH POWER AND HIGH TEMPERATURE ELECTRONIC DEVICES ARE IMPORTANT IN BOTH DEFENSE AND COMMERCIAL SYSTEMS. BETA SILICON CARBIDE IS AN EXCELLENT CANDIDATE SEMICONDUCTOR MATERIAL FOR DEMANDING APPLICATIONS DUE TO ITS HIGH BREAKDOWN VOLTAGE, RELATIVELY LARGE BAND GAP, HIGH THERMAL CONDUCTIVITY AND HIGH MELTING POINT. USE OF SILICON CARBIDE THIN FILMS IS HAMPERED, HOWEVER, BY THE INABILITY TO REPRODUCIB ...

IN-SITU MONITORING OF CRITICAL FILM PROPERTIES WOULD GREATLY ENHANCE PROCESS CONTROL OF THIN FILM COATING TECHNOLOGIES SUCH AS CHEMICAL VAPOR DEPOSITION (CVD) AND PHYSICAL VAPOR DEPOSITION (PVD). ATM, WORKING IN CONJUNCTION WITH PENNSYLVANIA STATE UNIVERSITY, PROPOSES TO INCORPORATE A POSITION SENSITIVE FIBER OPTIC X-RAY SCINTILLATION DETECTOR (PSSD) FOR REAL TIME X-RAY ANALYSIS OF CHEMICALLY VAPO ...

SEMICONDUCTING DIAMOND HAS MANY NOVEL PROPERTIES, MOST NOTABLY A STABLE NEGATIVE ELECTRON AFFINITY SURFACE. CONDUCTION BAND ELECTRONS ARE READILY EMITTED FROM A NEGATIVE ELECTRON AFFINITY (NEA) MATERIAL BECAUSE THE BULK CONDUCTION BAND LIES ABOVE THE VACUUM LEVEL. IN THE PHASE I PROGRAM WE WILL CONSTRUCT A NEGATIVE ELECTRON AFFINITY DIAMOND VACUUM COLLECTOR TRANSISTOR AND INVESTIGATE THE PERFORMAN ...
