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 ...

CONCENTRATION FLUCTUATION MEASUREMENTS OF A TRACER GAS CAN PROVIDE INFORMATION REGARDING THE DISPERSION AND TRANSPORT OF AN AIR MASS. THERE HAS BEEN A DEARTH OF SUCH DATA BECAUSE OF A SHORTAGE OF INEXPENSIVE, SIMPLE-TO-OPERATE INSTRUMENTATION MEETING THE NECESSARY REQUIREMENTS OF FAST RESPONSE, HIGH SENSITIVITY, AND STABILITY. IT IS THE GOAL OF THIS RESEARCH PROGRAM TO DEVELOP AN INEXPENSIVE, HIGH ...

This proposal describes the development of an instrument based on laser-induced breakdown spectroscopy (LIBS) for the detection of lead in paint and soil that will have both military and commercial applications. The Phase I instrument will be similar to multi-species, portable LIBS instruments built by Dr. David Cremers at Los Alamos National Laboratory that utilize a spectrograph/charge coupled ...

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 ...

APPLIED TECHNOLOGIES, INC. PROPOSES A DESIGN PROGRAM TO DESIGN A SIMPLE, MOBILE, VERTICAL AXIS FM-CW RADAR. THE PROGRAM WILL ENCOMPASS A LITERATURE SEARCH TO FIND THE LATEST STATE-OF-THE-ART ADVANCES IN RADAR TECHNOLOGY. THE DATA FROM THE LITERATURE SEARCH WILL FORM THE BASIS FOR A DESIGN THAT INCLUDES ANTENNA DESIGN, TRANSMITTER DESIGN, RECEIVER DESIGN, AND DATA COLLECTION AND PROCESSING. COST TR ...

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 ...

THIS PROPOSAL DESIGNS A MAN PORTABLE AND DEPLOYABLE FOOTBRIDGE WITH THE BRIDGING CAPABILITY TO CROSS A 20 METER DRY GAP AND AN UNLIMITED WET GAP. THE BRIDGE IS DEPLOYABLE QUICKLY AND QUIETLY, AND ONLY REQUIRES ACCESS TO ONE SIDE OF THE GAP. THE DESIGN USES NEW LIGHTWEIGHT, HIGH-STRENGTH MATERIALS ALONG WITH STATE-OF-THE-ART COMPUTER OPTIMIZATION TECHNIQUES TO MAXIMIZE LOAD TO BRIDGE WEIGHT RATIOS. ...

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 ...
