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 ...

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 ...

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 ...

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 ...

Physics-based modeling and simulation tools for predicting electromagnetic interference (EMI) and vulnerability (EMV) between RF systems are playing an increasingly important role in system level performance predictions. In order to accurately capture all of the complexity associated with RF systems on a modern military platform, very sophisticated multi-physics simulators using models of multiple ...

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 electromagnetic interference and the goal of RF system designers and analysts is to achieve electromagnetic compatibility where no interference problems exist between the various RF systems ...

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 ...

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 ...
