Modern aircraft include numerous RF systems and associated antennas of diverse types. The designed performance of antennas is typically degraded by their installation on the airframe. Also, the presence of many RF systems in a small region creates enormous opportunity for undesired interference via antenna-to-antenna coupling. These conditions present serious challenges for engineers tasked with i ...

One of the most important problems encountered in an electromagnetic environment is that of providing compatibility between radiating and receiving RF equipment within the environment. This problem is a type of EMI and the goal of RF system designers and analysts is to achieve EMC where no interference problems exist. We propose to develop a software tool named Electromagnetic Interference Toolki ...

Environmental degradation of aerospace turbine components is a major concern for aircraft and power generation systems, and various surface treatments are utilized to extend the lifetimes of these critical components. This Phase II project is targeted toward extending the durability of thermal barrier coatings (TBCs) on hot section turbine components. TBCs are highly susceptible to degradation b ...

The United States Navy (USN) uses a number of high strength steels, primarily AerMet100, in demanding landing gear structural applications. Unfortunately AerMet100 is expensive and, despite impressive mechanical properties, is subject to stress corrosion cracking (SCC) and requires plating operations for corrosion resistance. In a recently completed Phase I SBIR program QuesTek Innovations applied ...

Today\'s submarine towed array handling system operating parameters an methods are equivalent to those used in the late sixties. Attempts to utilize conventional cable handling methods are not suitable for array handling, and appropriate methods have not yet been defined. Outboard system volume, weight, system complexity, installation complexity, and cost far exceed acceptable standards for a hand ...

During Phase I, the authors extended the development work for an automated microfactory that began with a prototype developed at the University of Illinois at Urbana-Champaign in 2005 as part of a grant from the US Army Aviation and Missile Command. The prototype provided proof-of-concept for important microfactory technologies, and revealed gaps between the state-of-the-art and the Navy microfac ...

An integrated experimental and computational investigation of non-conventional nozzles and series of nozzles in crosswind environments is proposed. The experiments will be conducted at the University of Illinois and will provide a validation test bed for numerical simulations. High-fidelity three-dimensional simulations will be conducted using the proprietary framework Rocstar. This experimental a ...

This program is intended to advance the state-of-the-art d36 shear mode projector. Phase I of this effort produced a projector which demonstrates promising bandwidth and source level, especially considering its compact size. It is also the first known d36 underwater projector in the history of piezoelectrics. To develop a robust, high power, and broad bandwidth d36 shear mode projector array and b ...

Under the Phase I project, we have developed a Polarimetric Imaging System (PIS), integrated it with the 3-D Flash Ladar (FL), and have demonstrated operation of the integrated device: a PLADAR (Polarimetric Ladar). Furthermore, we have performed a detailed study of the ability of the PLADAR system to see parts of a scene that are not visible under intensity-only imaging. We have also shown how ...

PAVEMENT DISTRESS DATA ARE UTILIZED DURING PAVEMENT EVALUATION, DESIGN, REHABILITATION, MAINTENANCE, MANAGEMENT, AND RESEARCH. CURRENTLY, THE MANUAL SURVEY METHOD, UTILIZING PAPER AND PENCIL, IS USED EXTENSIVELY IN COLLECTING THE DISTRESS DATA, BUT THIS PROCESS IS SLOW, TEDIOUS, EXPENSIVE, AND PRONE TO HUMAN ERROR. THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP A COMPUTERIZED PAVEMENT DISTRESS DATA ...
