The primary objective of this proposed work is to develop a method of producing integrally stiffened, complex shaped monolithic structural components in high strength aluminum alloys at a lower cost and lighter weight than equivalent conventional built-up assemblies. In Phase I the feasibility of attaining this objective will be demonstrated by conducting a series of subscale experiments based upo ...

This proposal is directed at creating discontinuous unidirectional composite from continuous unidirectional prepreg. The process, Selectively-Discontinuous-Fiber (SDF), introduces micro-cuts in preimpregnated unidirectional materials at specified locations. This process will allow unidirectional composite prepreg to be used for the fabrication of complex-compound components that have be ...

DEVELOPMENT OF A PLAN AND ITS DEMONSTRATION IN PRODUCING MODERN DATABASE FOR RV TECHNOLOGIES IS PROPOSED BY USING CLOUD MICROPHYSICAL DATA SETS COLLECTED SINCE 1985 OVER THE NORTH AMERICAN CONTINENT AND U.S. ARMY KWAJALEIN ATOLL. THE PLAN INCLUDES THE USE OF AIRBORNE RADAR, MODELING, AND SATELLITE ADDITIONS TO THE PARTICLE SIZE DATA TO CORRELATE PARTICLE SIZE AND LIQUID WATER CONTENT OVER AN EXTEN ...

Measuring temperature in specimens being heated by electromagnetic energy requires the use of special probes. The temperature probes must be specially designed to minimize electromagnetic field perturbations. Several types of non-perturbing temperature measurement probes have been investigated and developed. Many employ optical fibers rather than electrical conductors to avoid the e ...

Beam Technology Corporation is prepared to develop an innovative personal Radio frequency Radiation Dosimeter based on concepts originally enunciated by Dr. Johnathan Kiel, The approach will use a technology that promises to be much more versatile than currently available methods of measurement, which often employ E-field probes and meters. The objective is to use a novel chemical, Diazoluminomel ...

The CFTF Centrifuge at Armstrong Laboratory will be a useful tool for crewmember training and human factors research for future high performance aircraft. The centrifuge features an accelearation of performance that is unmatched by other Air Force facilities, however, it lacks a set of powered gimbals that would allow positioning of the rider with respect to acceleration. With these additional d ...

ACCURATE AND EFFICIENT PREDICTION OF SKIN FICTION AND HEATING RATES FOR SUPERAND HYPERSONIC VEHICLES HAS LONG BEEN A GOAL OF COMPUTATIONAL FLUID DYNAMICS (CFD). THE USE OF STANDARD CFD METHODS TO RESOLVE THE NEAR-WALL BOUNDARY LAYER (WHICH IS ESSENTIAL FOR GOOD PRECITIONS OF AIRFOIL BEHAVIOR) USING A LARGE NUMBER OF GRID POINTS IS SELDOM FEASIBLE, OFTEN INACCURATE, AND IF DONE, ALWAYS REQUIRES EXC ...
