NEW GENERATION HIGH-TEMPERATURE MATERIALS ARE BEING DEVELOPED FOR A HOST OF APPLICATIONS SUCH AS THE NATIONAL AEROSPACE PLANE (NASP). CARBON-CARBON COMPOSITES SHOW GREAT PROMISE FOR THIS APPLICATION BECAUSE OF THEIR HIGH STRENGTH AND STIFFNESS AT ELEVATED TEMPERATURES.IN ORDER TO FULLY UTILIZE THE HIGH-TEMPERATURE ADVANTAGES OF CARBONCARBON, OXIDATION COATINGS ARE BEING DEVELOPED AND APPLIED TO CA ...

COMPRISES IN WIND TUNNEL OPERATIONAL PARAMETERS, RELATIVE TO ACTUAL ATMOSPHERIC FLIGHT, AND INADEQUACINES IN NUMERICAL SIMULATIONS INDICATE THE REQUIREMENT FOR A NONINTRUSIVE DIAGNOSTIC TECHNIQUE WHICH CAN ENABLE PROFILES OF KEY PLASMA BOUNDARY LAYER PARAMETERS (E.E., ELECTRON DENSITY AND ELECTRON COLLISION FREQUENCY) TO BE DIRECTLY MEASURED IN REAL FLIGHT OR WIND TUNNEL ENVIRONMENT. WE PROPOSE AN ...

THE PROPOSED EFFORT IS INTENDED TO PROVIDE IN DEPTH TECHNOLOGICAL SUPPORT TO THE ARNOLD ENGINEERING DEVELOPMENT CENTER (AEDC) FOR THE INTERPRETATION AND EVALUATION OF THE RELATION BETWEEN THE MAJOR PULSE FORMING DEVICES IN THE ADVANCED PULSEPOWER SYSTEMS USED IN CONJUNCTION WITH INDUCTIVE ENERGY-STORAGE TECHNOLOGY. PARTICULAR EMPHASIS IN PHASE I WILL BE ON THE CONTROLLED ELECTROMAGNETIC IRRADIATIO ...

THE GOAL OF THE PROPOSED RESEARCH IS TO DEVELOP A THEORETICAL MODEL OF DIAMOND FILM DEPOSITION SO THAT THERE WILL BE A SIMULATION GUIDE FOR EXPERIMENTAL WORK. THERE IS A CONCEPTUAL SIMILARITY BETWEEN THE ISING MODEL AND CELLULAR AUTOMATA (CA), BOTH OF WHICH USE ARRAYS OF CELLS WHOSE STATES DEPEND ON THE STATES OF THE NEIGHBORING CELLS. THE CELLULAR AUTOMAT (CA) MODEL USES "TRANSITION RULES" TO DET ...
