THERE IS, AT PRESENT, NO COMMERCIALLY AVAILABLE NON-CONTACT DEVICE WHICH CAN ACCURATELY MEASURE TEMPERATURES WITHOUT PRIOR KNOWLEDGE OF THE EMISSIVITY OF THE MATERIAL BEING SAMPLED. WE PROPOSE TO INVESTIGATE THE FEASIBILITY OF CONSTRUCTING A PYROMETER SYSTEM CAPABLE OF ACCURATELY MEASURING TEMPERATURES AND EMISSIVITIES IN THE TEMPERATURE RANGE OF 300 TO 2000 C. THE DEVICE WILL EMPLOY SEVERAL RADIO ...

THE EFFECT OF ATMOSPHERE-INDUCED RADIATIVE EMISSIONS ON SEN-SOR SYSTEMS OF KINETIC ENERGY WEAPONS WILL BE INVESTIGATED. AT THE HIGH VELOCITIES OF PALNNED KINETIC ENERGY WEAPONS, COLLISIONS WITH IN VEHICLE SENSOR BANDWIDTHS. THESE EMISSIONS WOULD BE FROM ELECTRONICALLY EXCITED MOLECULAR STATES IN THE UV/VISIBLE AND FROM HIGHLY VIBRATIONALLY EXCITED STATES IN THE IR. THUS, MANY SENSOR BANDPASSES MAY ...

WE PROPOSE TO DEVELOP TWO LASER-BASED TECHNIQUES TO MONITOR POPULATIONS OF HIGHLY VIBRATIONALLY EXCITED GROUND ELECTRONIC STATE N(2)(X,V>>0) IN A CHEMICAL LASER ENVIRONMENT. THE TECHNIQUES ARE NON-INTRUSIVE POINT DIAGNOSTICS WITH POTENTIAL DETECTION SENSITIVITIES AS LOW AS 10(12) MOLECULES CM -3. ONE TECHNIQUE INVOLVES THE USE OF MULTIPHOTON IONIZATION SPECTROSCOPY (MPI) TO IONIZE N2(X,V) WITH FOU ...

A METHOD FOR DETERMINING INCIPIENT ICE LAYER FORMATION ON PAVED SURFACES IS TO BE DEMONSTRATED. THE PROPOSED TECHNIQUE WILL RELY UPON THE ENHANCEMENT IN SPECULAR REFLECTANCE, I.E., "GLARE," THAT WILL OCCUR WHEN AN OVERLYING ICE LAYER FORMS ON A PAVED SURFACE. THE PROPOSED INVESTIGATIONS WILL ALSO EXPLORE HOW OVERLYING ICE LAYERS MODIFY THE BACKSCATTERED RADIATION OBSERVED OFF PAVEMENT SURFACES. TH ...

THE PROPOSED RESEARCH IS DIRECTED TOWARDS IMPROVING THE EFFICIENCY OF THE CHLOR-ALKALI PROCESS BY PRODUCING HYDROGENCHLORIDE IN A COGENERATING FUEL CELL. HYDROGEN CHLORIDE IS USED TO ACIDIFY THE BRINE ANOLYTE USED IN THE PRODUCTION OF CHLORINE AND CAUSTIC SODA. BRINE ACIDIFICATION IS REQUIRED TO AVOID AN UNDESIRED PARASITIC ANODE REACTION. THE HYDROGEN CHLORIDE USED FOR BRINE ACIDIFICATION IS EITH ...

WE PROPOSE TO PREPARE A MATERIAL IN WHICH A HIGHLY DISPERSEDCATALYST IS CHEMICALLY BONDED TO A CARBON FILAMENT SUPPORT MATERIAL FOR USE IN THE FABRICATION OF CATHODES FOR ALKALINEFUEL CELLS. THE CARBON FILAMENTS WILL BE GROWN ON GOLD OR GOLD ALLOY CATALYSTS FROM HOT FLOWING GASES. THE ELECTROCATALYST IS EXPECTED TO EXHIBIT THE IMPROVED SINTERING AND CORROSION RESISTANCE NEEDED FOR PRESSURIZED ALKA ...

A SERIES OF LABORATORY EXPERIMENTS WILL BE CONDUCTED TO INVESTIGATE THE FEASIBILITY OF USING AN ACOUSTIC-BASED DETECTION TECHNIQUE AS A REAL-TIME, IN SITU INDICATOR FOR LASER-INDUCED KIDNEY/GALLSTONE FRAGMENTATION. THE AIM WILL BE TO ESTABLISH A RELIABLE CORRELATION BETWEEN THE ACHIEVE- MENT OF STONE DEMISE DUE TO LASER-DRIVEN FRAGMENTATION AND THE RESULTING ACOUSTIC SIGNATURE GENERATED. IF SUCCES ...

A LASER-ASSISTED, THERMOMECHANICAL PROCESS IS PROPOSED FOR CLADDING OF HIGH MELTING REFRACTORY METALS ON LOW MELTING SUBSTRATES WITHOUT MELTING OR DAMAGING THE UNDERLYING SUB- STRATE. THE PROCESS CAN BE ADAPTED, WITH POST-CLADDING TREATMENTS, FOR PRODUCTION OF REFRACTORY METAL OXIDE, AND CARBIDE COATINGS FOR HIGH TEMPERATURE OXIDATION AND WEAR RE-SISTANCE. THE PROPOSED PROCESS PROVIDES FOR CLADDIN ...

WE PROPOSE A THREE PART, PHASE I, PROGRAM OF DIRECT INTEREST TO SCRAM JET COMBUSTOR DESIGN WHICH LAYS A PROPER FOUNDATION FOR HIGH-ENTHALPY,SUPERSONIC COMBUSTING FLOW EXPERIMENTS SUITABLE FOR A PHASE II PROGRAM. BOTH PHASE I AND II RESEARCH EFFORTS FOCUS ON FUEL/AIR MIXING, WHICH WILL SIGNIFICANTLY AFFECT IGNITION AND FLAME HOLDING PERFORMANCE. A SPECIFIC INJECTOR CONFIGURATION, WHICH PRODUCES INT ...
