THIS PROGRAM ADDRESSES THE KEY PROBLEM IN THE DEVELOPMENT OF LIGHTWEIGHT COMPOSITE WAVEGUIDES, NAMELY THE SELECTION OF SUITABLE PROCESS\MATERIAL TO PROVIDE IF THE NECESSARY INTERIOR CONDUCTIVE COATING. A SURVEY OF THE WIDE VARIETY OF ABALABLE MEHTODS IS PERFORMED WITH THE SPECIFIC REQUIREMENTS OF WAVEGUIDES IN MIND. TWO CONDUCTIVE COATING METHODS ARE THEN

COMPOSITE MATERIALS SUCH AS GRAPHIT/EPOXY AND KEVLAR/EPOXY OFFER THE POTENTIAL TO REDUCE WEIGHT, RADAR CROSS SECTION (RCS), AND MANUFACTURED COSTS IN FLIGHT VEHCILE STRUCTURES. THIS PROGRAM IS DESIGNED TO APPLY THESE BENEFITS TO AFAL'S LOW ALTITUDE DISPENSER (LAD). AT THE SAME TIME THE CURRENT 11" PAYLOAD BAY WOULD BE INCREASED TO 12" TO INCREASE PAYLOAD VOLUME AND EFFICIENT MUNITIONS PACKING. AFT ...

THIS PROJECT IS TO DEVELOP AN IMPROVED NON-INTRUSIVE METHOD OF TEMPERATURE DETERMINATION FOR PULVERIZED COAL COMBUSTION BASED ON FT-IR SPECTROSCOPIC MEASUREMENT OF ITS EMISSIONS. IN PHASE I SPECTRAL MEASUREMENTS WILL BE MADE OF THE RADIATION FROM COMBUSTING COAL PARTICLES IN A LABORATORY FURNACE. TEMPERATURE DETERMINATION WILL BE ACCOMPLISHED USING VISUAL AND ANALYTIC COMPARISON TECHNIQUES, THE LA ...

IN THE PROCESSING OF SOLIDS, RAPID METHODS ARE NEEDED TO DETERMINE ORGANIC AND MINERAL PARAMETERS WHICH CAN BE RELATED TO PROCESS BEHAVIOR. THIS PROPOSAL SUGGESTS THE DEVELOPMENT OF PHOTOACOUSTIC FOURIER TRANSFORM INFRARED (PA-FT-IR) SPECTROSCOPY FOR ON-LINE MONITORING OF FOSSIL FUEL FEEDSTOCKS AND PROCESS STREAM SOLIDS FOR THE FOLLOWING REASONS: (A) FT-IR TECHNIQUES HAVE RECENTLY BEEN DEVELOPED W ...

IF COAL WATER FUELS (CWF) ARE TO BE USED WITH THE CONVENIENCE AND RELIABILITY OF LIQUID OR GASEOUS FUELS, CHOICES MUST BE MADE IN SLURRY FORMULATION, COAL RANK, DEGREE AND METHOD OF CLEANING, ATOMIZATION TECHNOLOGY, COMBUSTION PARAMETERS, AND SORBENT ADDITIVES. A LABORATORY-SCALE METHOD IS NEEDED FOR TESTING CWF WHERE THE RESULTS CAN BE RELATED TO THE FUEL'S PERFORMANCE IN FULL-SCALE DEVICES. A RE ...

THE ATMOSPHERE CONTAINS MANY NATURALLY OCCURRING AND MANMADE FINE PARTICLES AND AEROSOLS. THESE PARTICLES AFFECTWEATHER, AIR QUALITY AND COMMUNICATIONS. KNOWLEDGE OF THEIRCONCENTRATION, COMPOSITION, DISTRIBUTION AND TRANSPORT IS IMPORTANT TO THE PREDICTION OF WEATHER, DETECTION AND CONTROL OF POLLUTION, HEALTH MONITORING OF VEGETATION AND ATMOSPHERIC CHEMISTRY. WHILE A METHODS PRESENTLY EXIST FOR ...
