GAASP SOLAR CELLS PLACED ON TOP OF CONVENTIONAL SILICON SOLAR CELL ARRAYS CAN INCREASE THE ENERGY CONVERSION EFFICIENCY OF THE SYSTEM AS MUCH AS 100%. ASTROPOWER DIVISION OF ASTROSYSTEMS, INC. PROPOSES TO DEVELOP A HIGH BAND GAP TOP SOLAR CELL FOR ATTACHMENT TO CONVENTIONALS ILICON SOLAR CELLS. TRANSPARENT GAP SUBSTRATES WILL BE USED WITH EPITAXIALLY GROWN LAYERS OF GAASPH HAVING A BAND GAP OF 1.7 ...

This project will create a distributed portal and virtual testbed for ATR/Fusion algorithms. The investigators will develop a CORBA architecture and software tools to support profiling of distributed software processes, workflow task management, andinterfaces to algorithm and performance measure repositories. The investigators will design and create databases for algorithm inputs, algorithm outp ...

A SYSTEM UTILIZING THE FREE-WING CONCEPT HAS BEEN DESIGNED FOR LIGHT AND VERY LIGHT WING-LOADING AIRCRAFT THAT ACCOMMODATES MODERATE TO HEAVY TURBULENCE WITHOUT TRANSMITTING HIGH GUST LOADINGS TO THE AIRFRAME OR THREATENING LOSS OF CONTROL. THE PROJECT WILL TEST THE SYSTEM IN A RESEARCH VEHICLE APPROXIMATING THE DESIGN CRITERIA SET FORTH IN 14 CFR, PART 103; THE RESEARCH VEHICLE IS UNMANNED.

InnoSys proposes the advanced development of microwave power modules (MPMs) that combine monolithic microwave integrated circuit (MMIC) driver amplifiers with miniature traveling wave tube (TWT) amplifiers. This provides high power density at low cost and a small size and weight. When used as a driver amplifier in the MPM, the V/W band MMIC provides sufficient power and gain to drive the special ...

Current high-energy computed tomography (CT) techniques for nondestructive testing (NDT) of solid rocket motors (SRM) and other large industrial objects often produce inferior imagery due to artifacts, impairing detection, identification, and measurement of anomalies. Phase I results verified that these artifacts arise from failure of assumptions implicit in the filtered backprojection algorithm. ...

A SIX MONTH PROGRAM TO DEVELOP A RUGGED NEW DEVICE FOR MONITORING THE ONSET OF ICE FORMATION ON SURFACES OF TRANSPORTATION VEHICLES, ROADS, BRIDGES AND AIRCRAFTS, WILL BE DEVELOPED AND A PROTOTYPE WILL BE LABORATORY TESTED. THE NOVEL GAGE AND ELECTRONIC SYSTEM IS PARTLY BASED ON THE TECHNOLOGY APPLIED TO MEASURE CONDUCTIVITY OF SOLUTIONS. BASED ON EXISTING TECHNOLOGY, AND ALREADY TESTED UNDER HIGH ...

THE OBJECTIVE OF THE PROPOSED STUDY IN PHASE I IS TO DEVELOP A NOVEL AND COMPREHENSIVE ALGORITHM FOR THE RETRIEVAL OF THE COMPOSITIONS AND STRUCTURE OF CIRRUS CLOUDS USING DATA GATHERED FROM ORBITING METEOROLOGICAL SATELLITES. IN THE PROPOSED PROGRAM, THE TEMPERATURE, EMISSIVITY AND FRACTIONAL COVER OF CIRRUS CLOUDS ARE FIRST DETERMINED FROM NOAA-AVHRR AND DMSP-OLS RADIANCE DATA. ONCE THE CIRRUS C ...

Scheduling is a complex, NP-hard problem that challenges the use of any single solution technique. In Phase I, we built a model that uses our multi-technique Quantum Leap Problem Solving Engine to solve a representative but simplified version of the AirForce Satellite Control Network (AFSCN) contact scheduling problem. The system demonstrated that it could schedule the hundreds (500 to 600) of t ...

Computational fluid dynamics (CFD) is playing an increasingly important role in U.S. industry. In the aerospace industry, where the cost of construction and operation of sub-scale and prototype units increases significantly with the increase in size andspeed of aircraft, CFD plays an important role as an adjunct to experimentation in reducing the costs of testing and scale-up and the time to take ...

During the last two decades, there has been considerable interest and research in inorganic polymers (“geopolymers”) for high-temperature applications. Geopolymers are manufactured by combining aluminosilicate powders with activating liquids through a polycondensation reaction. The resulting cured geopolymer can exhibit high compressive strengths after only four hours of set time. Geopolyme ...
