While circuit simulation tools have revolutionized the art of RF and microwave design, these tools are only as good as the component values they employ. The increased demand for reduced design cycles and easier to manufacture systems has generated the need for accurate and reliable tools. Current circuit simulation tools use component models that do not always account for parasitic coupling, non ...

Specific mechanical properties of fiber-reinforced composites have made them an attractive material for application to many aircraft structures. Today, composite structure is typically made up of laminated layers (plies) of 2-D composite material with the fiber direction of each ply thoughtfully oriented to optimize structural efficiency. The goal of 'continued improvement' in structural efficie ...

We propose to develop automatic rezoning algorithms for general-purpose 2-D and 3-D Lagrangian hydrocodes. Rezoning allows treatment of ballistic problems involving very large deformations, such as warheads and penetrations. Unlike erosion techniques, rezoning allows continued modeling of failed material. A previously developed and demonstrated 2-D rezoning algorithm will be extended to 3-D thr ...

The goal of this effort is to develop optical interconnection technology for high performance image processing. Conventional intra-computer electrical communication, for example between multi-chip modules (MCMs), is a limiting problem in future image processors. The pin count needed between high performance image processing MCMs is a problem. In this effort we explore potential high density opt ...

Throughout the United States and around the world, a variety of industries are moving from conventional to high flash solvents, including dibasic and other esters, glycol ethers, and terpenes (d-limonene isomers). For instance, approximately 80% of the cleaning solvents used in the screen printing industry, representing more than $50 million per year in solvent sales, are high flash solvents. Al ...

The goal of this effort is to develop high efficiency optical switching systems based on free space switchable gratings. The use of switched gratings as an enabling technology to arbitrarily steer RF modulated optical carriers from 1 to any of N channels or alternatively from among N input to N output channels has several distinct advantages over other photonic switching systems including: 1) low ...

GaAs based Quantum Well Intersubband Photodetectors (QWIP) are attractive devices for large staring Focal Plane Arrays (FPA) at mid- and long- infrared wavelengths. The mature GaAs processing technology allows larger arrays with higher pixel operability and better uniformity to be manufactured at lower cost than competing technologies that can access both the MWIR (3-5 micron) and LWIR (8-12 micr ...

RedZone Robotics, Inc. proposes to develop an innovative robotic laser induced surface improvements system (LISI) to meet test facilities requirements of USAF AEDC. The project goal is to demonstrate an easily deployed, rapidly recovered robotic laser and alloy delivery system to improve corroded AEDC duct surfaces at a rate of at least 20 square feet per hour. The system will consist of three m ...

The principal objective of the proposed effort is to enhance the Vehicle Integrated Thermal Management Analysis Code (VITMAC) to include an optimization scheme, at the component and system levels, that will provide an optimum thermal design ensuring minimum weight while satisfying cooling requirements. Additiionally, VITMAC will be coupled with an engine performance code to obtain better estimate ...
