INTERMETALLIC COMPOUNDS ARE KNOWN FOR THEIR HIGH MELTING POINTS AND CORROSION AND OXIDATION RESISTANCE. MANY OF THESE COMPOUNDS HAVE LOW DENSITIES AND VERY HIGH STRENGTHS AND, THEREFORE, ARE OF INTEREST FOR HIGH TEMPERATURE AEROSPACE AND SPACE STRUCTURE APPLICATIONS. HOWEVER,CONVENTIONAL PROCESSING OF INTERMETALLIC COMPOUNDS SUFFERS SEVERE LIMITATIONS: REACTIONS WITH CONTAINERS, POROSITY, CONTAMIN ...

MAJOR TECHNOLOGICAL ADVANCES IN MATERIAL ENGINEERING WILL BE REQUIRED IN ORDER TO MEET THE INCREASINGLY STRINGENT CONSTRAINTS OF HIGH STIFFNESS AND LOW WEIGHT STRUCTURAL MATERIALS FOR AEROSPACE VEHICLES. SIGNIFICANT EFFORT IS BEING SPENT ON DEVELOPING NEW EXOTIC METAL ALLOYS AND COMPOSITE MATERIALS IN AN ATTEMPT TO SATISFY THE STATED CHALLENGE. AN ALTERNATE APPROACH TO BE CONSIDERED IS THE CREATIO ...

THE USE OF MULTIPLE SENSORS FOR ELECTRONIC SIGNAL UNDERSTANDING HAS IMPORTANT ADVANTAGES. MULTIPLE VIEWING ANGLES CAN PROVIDE MULTIPLE DIRECTION FINDING, MULTIPLE DOPPLER MEASUREMENTS FOR TARGET VELOCITY DETERMINATION, ROBUSTNESS AGAINST TERRAIN MASKING/SPOOFING, ETC. ALTHOUGH THE DATA FROM MULTIPLE SENSORS CAN BE SENT TO A CENTRAL SITE FOR PROCESSING, A DISTRIBUTED ELECTRONIC SIGNAL UNDERSTANDING ...

CARBON-CARBON COMPOSITES ARE INCREASINGLY BEING EMPLOYED IN ADVANCED DOD SYSTEMS. THE LENGTH AND COMPLEXITY OF THE MANUFACTURING PROCESS OF THESE COMPONENTS TEND TO MAKE THE PARTS COSTLY AND THE YIELDS LESS THAN OPTIMAL. AN ONGOING DARPA PROGRAM AIMS AT DEVELOPIG AN INTELLIGENT CONTROL SYSTEM WHICH INTEGRATES PROCESS MODELING, OPERATOR KNOWLEDGE, AND IN-PROCESS SENSORS TO IMPROVE THE RELIABILITY, ...

THE OBJECTIVE OF THIS RESEARCH IS TO DEMONSTRATE THE FEASIBILITY OF FUSING DATA OBTAINED SIMULTANEOUSLY FROM VISIBLE, INFRARED AND RADAR SENSORS, TO PROVIDE A HERETOFORE UNOBTAINABLE SURVEILLANCE CAPABILITY.THE DIFFICULTIES ASSOCAITED WITH SENSOR FUSION WHICH WILL BE ADDRESSEDINCLUDE THE DIFFERENT FIELDS OF VIEW, DIFFERENT MEASUREMENTS, DIFFERENT RESOLUTIONS, AND DIFFERENT POSITIONS AND VELOCITIES ...

DARPA HAS IDENTIFIED A NEED FOR NEW AND IMPROVED TECHNIQUES FOR COATING CERAMIC FIBERS FOR SUBSEQUENT INCORPORATION INTO METALLIC, CERAMIC OR HYBRID MATRICES. AMERICAN MATRIX, INC.'S PHASE I PROGRAM ADDRESSES THE SIGNIFICANT PERFORMANCE ATTRIBUTES (DEFINED BY DARPA AS INTERFACE CHEMICAL REACTION INHIBITION, INTERFACE BOND DEVELOPMENT,AND TAILORED PROPERTIES) WITH A MULTI-FACETED COATING PROGRAM. S ...

A METHOD FOR DETECTING BURIED PLASTIC MINE IN PRESENTED WHICH EMPLOYS THE ACTIVATION OF NITROGEN BY 14 MEV NEUTRONS AND THE SUBSEQUENT DETECTION OF EMITTED 7 MEV GAMMA RAYS. THE DETECTION SYSTEM IS TRANSPORTED BY A REMOTELY PILOTED VEHICLE WHICH PROVIDES THE REQUIRED STANDOFF DISTANCES.

COMPUTATIONAL FLUID DYNAMICS (CFD) CODES HAVE BECOME IMPORTANT DESIGN AND ANALYSIS TOOLS FOR ENGINEERS, PARTICULARLY IN THE AEROSPACE INDUSTRY. CFD CODES, HOWEVER, ARE SEVERELY LIMITED BY THE COMPUTING RESOURCES OF PRESENT-DAY SUPERCOMPUTERS. IT IS ESTIMATED THAT A THREE ORDER-OF-MAGNITUDE INCREASE IN COMPUTER SPEED IS NECESSARY FOR PERFORMING PRACTICAL ENGINEERING VISCOUS-FLOW ANALYSES OF FULL AI ...
