THIS PROJECT FOCUSES ON THE TWO MOST IMPORTANT ISSUES OF ALL OF COMPUTATIONAL FLUID DYNAMICS: 1) HOW GOOD ARE THE NUMERICAL ANSWERS OBTAINED IN A COMPUTATION? AND 2) HOW CAN THE BEST POSSIBLE ANSWERS BE OBTAINED FOR A FIXED AND LIMITED COMPUTATIONAL EFFORT, BUDGET, OR COMPUTING CAPABILITY? IN GENERAL TERMS THE ANSWERS TO THESE QUESTIONS ARE 1) TO DETERMINE RELIABLE A-POSTERIORI ESTIMATES OF ERROR ...

AN INNOVATIVE APPROACH TO FORMING A NULL IN THE SECONDARY PATTERN OF A REFLECTOR ANTENNA IS DEVELOPED BY THIS PROJECT. AN ELECTRONICALLY CONTROLLABLE REFLECTIVE SURFACE BEING DEVELOPED ON A NASA SBIR IS THE STARTING POINT FOR THE WORK. THIS PROJECT EXTENDS THE PERFORMANCE OF THE SURFACE SO THAT IT IS USEFUL AS A NULL FORMER. THE RESULT IS CONSIDERABLY REDUCED COST OF NULL STEERING ANTENNAS. THE DE ...

"ABSTRACT: Modern electronic and opto-electronic devices are predicated on controlled deposition and patterning of functional material layers (e.g. semiconductors, conductors, and dielectrics). A handful of techniques, including vacuum epitaxy and chemical vapor deposition, in conjunction with lithographic micromachining methods, have long dominated the manufacture of these systems, particularly ...

ABSTRACT:Modern electronic and opto-electronic devices are predicated on controlled deposition and patterning of functional material layers (e.g. semiconductors, conductors, and dielectrics). Vacuum epitaxy and chemical vapor deposition, in conjunction with lithographic methods, have dominated the manufacture of these systems. While these techniques are well-established and routinely deliver relia ...

Dominance in hypersonic systems is necessary to counter emerging threats from near-peer states which are aggressively developing their own hypersonic capabilities. An important part of the Air Force’s projected future capabilities is reusable hypersonic aircraft with the ability to operate from conventional fields and accelerate to speeds of Mach 5 or above. These aircraft could perform a v ...

ABSTRACT: The current state-of-the-art for heat exchanger (HEX) analysis and design relies on analytical approaches which are difficult to scale and highly empirical, thus making the ability to optimize advanced heat transfer devices improbable without comprehensive characterization efforts. The design standard for predicting heat exchanger performance is a set of empirical data developed more th ...

ABSTRACT: The future of gas turbine engines needed for propulsion and power in small unmanned military aircraft will hinge on the ability to enhance the efficiency for low fuel burn while maintaining world-class performance. Florida Turbine Technologies, Inc. (FTT) is developing the Advanced Recirculating Total Impingement Cooling (ARTIC) technology to enable a revolutionary leap in gas turbine e ...

We propose a resilient silver flake based metallization technology directly printable onto multijunction solar cells. The metallization will be loaded with carbon nanotubes to improve crack resilience. We will demonstrate that we can maintain connectivity (< 5% performance degradation) of a printed front-side metal layer across a gap up to 30 microns. In Phase I, we demonstrated metal line resisti ...

The objective of this Phase II research is to perform advanced testing of second-generation solvent replacements used for cleaning hydrocarbon and fluorocarbon residues from oxygen systems. The advanced testing includes determining flammability,autogenous ignition temperature in oxygen, atmospheric impact, toxicity, and characterization of the thermophysical properties of the candidate solvents. ...
