Higher inlet temperatures for turbine engines will provide significant benefits in fuel efficiency and performance for both military and commercial air vehicles. To accomplish this goal, new generation thermal barrier coatings (TBCs) with superiorreliability and durability will be needed. The currently-used zirconia-based TBCs do not adequately meet thermal conductivity requirements and they suf ...

We propose to design, fabricate, and test a novel x-ray detector for use in industrial CT scanners. This linear detector array combines high spatial resolution and long array length to achieve high-resolution scans on large objects. We propose to supplyan x-ray scanner to the Army Research Laboratory for non-destructive testing that includes this linear array with a commercial flat-panel area de ...

The primary objective of CU Aerospace's Phase II work will be to experimentally characterize the ElectriCOIL flow using advanced diagnostics and to demonstrate lasing of this electrically assisted chemical iodine laser. CU Aerospace (CUA) and theUniversity of Illinois at Urbana-Champaign (UIUC) believe that it is possible to construct a highly efficient electric generation scheme to provide the pr ...

A nearly universal trend in modern technology is the continued integration of systems, and their associated devices, on decreasingly smaller scales. While this has led to personal computers that offer more functionality and faster computational speeds, ithas also spurred the development of hybrid optoelectronic systems on a chip (SOCs). Currently, such SOCs are receiving significant interest fro ...

A nearly universal trend in modern technology is integrating systems, and their associated devices, on decreasingly smaller scales. Examples range from complete telecommunication systems on a chip to implantable medical devices smaller than human cells. The majority of these devices apply hybrid designs that integrate on a commensurate scale electronics with active and passive optical components. ...

The availability of large format, multicolor, high performance infrared focal plane arrays is of the utmost importance to future DoD missions. The semiconductor HgCdTe is the material of choice for multicolor arrays due to its bandgap tunabilitythroughout the infrared spectral range and its high quantum efficiency. Present day 2nd generation focal plane array technology, based on the hybridizati ...

High-performance HgCdTe infrared focal plane arrays (IRFPAs) sensing in the long-wavelength infrared (LWIR) region and advanced structures such as multi-color detectors required for future generation IRFPAs are highly desirable for various Air Forceapplications. Such device architectures require not only reliable extrinsic n- and p-type doping of HgCdTe but also the precise control of composition ...

We propose the development of high quality HgCdTe-based materials and high performance two-color detector arrays operating in the very-long wavelength infrared (VLWIR) spectral region. The fabrication of large format, high sensitivity focal plane arrays sensing in the VLWIR is highly desirable for various applications complementing Missile Defense, Army, Navy, and Air Force capabilities. They will ...

: The development of cost-effective manufacturing technique for PMN-PT based piezoelectric single crystals with enhanced capabilities is critical to the achievement of the new generation of acoustic transduction devices. In Phase I, feasibility of the novel technique was demonstrated. The objective of this research project is to continue development of reducing the manufacturing costs for large-si ...

The Navy has a critical need to measure temperatures at critical areas on the inner bore surfaces of large guns in order to insure appropriate action is taken in case of a misfire. In the case of a misfire, the gun crew must know the bore surface temperature in order to decide if they have time to safely remove the ammunition before enough heat has transferred from the hot barrel, possibly initi ...
