During Phase I we will advance and develop innovative Adaptive Critic based neural network control methodologies specifically for a Remotely Piloted Vehicle (RPV) based upon the aerodynamics of the National AeroSpace Plane (NASP). Phase II will involve the actual implementation which will prove these neurocontrol concepts. This work will be the first step in creating the complex aerocontroller for ...

Accurate Automation will design a weakly ionized gas drag reduction system for an advanced fixed wing aircraft. To this end we will develop a theoretical model for the WIG drag reduction phenomena, initiate a series of two dimensional shock tank experiments, evaluate the engineering feasibility of employing the technology on an operational aircraft, and perform a conceptual design for a wind tunn ...

BETTER METHODS TO DELIVER AND DISSEMINATE CARGO ARE NECESSARY TO FULLY EXPLOIT THE CAPABILITIES OF FUTURE INTRATHEATER AIRLIFTERS. THE ARMY'S AND AIR FORCE RENEWED EMPHASIS ON MOBILITY WILL REQUIRE GREATER PRODUCTIVITY BY TRANSPORTATION RESOURCES TO ACHIEVE NATIONAL OBJECTIVES. THE NECESSITATES A MORE THOROUGHLY-INTEGRATED TRANSPORTATION NETWORK. ADVANCED TECHNOLGIES, MATERIALS, AND INNOVATIVE ENG ...

THE OBJECTIVE OF THE PROPOSED WORK IS TO ANALYZE THE HYPERVELOCITY MODELS TESTED AT ARNOLD ENGINEERING DEVELOPMENT CENTER TO DETERMINE THE CAUSE OF NOSETIP FRACTURES. WE WILL ACCOMPLISH THIS GOAL BY PERFORMING TWOAND THREE-DIMENSIONAL FINITE ELEMENT ANALYSES OF THE HYPERVELOCITY MODEL USING DYNA2D AND DYNA3D. IF NECESSARY, WE WILL ALSO DO HYDRODYNAMIC ANALYSES OF THE GAS EXPANSION WHICH DRIVES THE ...

THE PROPOSED RESEARCH PROGRAM WILL PROVIDE AN EVALUATION TOOL FOR ASSESSING THE EFFECTS OF MANUFACTURING AND IN-SERVICE MATERIAL ANOMALIES ON SUBSEQUENT SOLID ROCKET MOTOR PERFORMANCE. THE EVALUATION TOOL CONSISTS OF A NONLINEAR FINITE ELEMENT PROGRAM WITH A COMPOSITE DAMAGE AND FAILURE CONSTITUTIVE MODEL. THE EVALUATION TOOL WILL BE VERIFIED BY CORRELATION WITH LABORATORY TESTS OF DESIGNATED COMP ...

ONE KEY PROBLEM IN MAKING LOW ABSORBANCE MEASUREMENTS IS THERANDOM NOISE GENERATED IN VARIOUS SYSTEM COMPONENTS SUCH AS PHOTODETECTORS, ETC. ANOTHER CLASS OF PROBLEMS ARE ENVIRONMENTAL IN ORIGIN, SUCH AS AIRBORNE OR SAMPLE-BORNE CONTAMINATION, AND SCHLIEREN EFFECTS. THE PROPOSED INSTRUMENT, BASED ON WELL KNOWN WAVELENGTH MODULATION TECHNIQUES, BUT NOVEL IN CERTAIN CRITICAL ASPECTS, SUBSTANTIALLY R ...

AIR BUBBLES TRAPPED IN POLAR ICE AT THE TIME OF ICE FORMATION PROVIDE VALUABLE CLUES TO AID IN OUR UNDERSTANDINGOF THE CAUSES OF GLOBAL CLIMATE CHANGE. IT IS VITAL IN THISEFFORT THAT THE AGE OF THE ICE (WHICH MAY BE 500,000 YRS. ORMORE IN SOME LOCATIONS) BE ESTABLISHED. PRESENTLY, THERE ISNO METHOD FOR DATING ICE ABSOLUTELY BEYOND 50,000 YRS. A NEW METHOD FOR DATING POLAR ICE IN THE RANGE OF 50,00 ...
