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 ...

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 ...

The objective in this exploratory development is to design, fabricate and test a dual-mode radome for a high speed missile application. Performance, cost and ease of manufacturing will be emphasized. Radome models will be produced to be as close toflight hardware as practical. The use of an insert to provide performance enhancements will be incorporated into the design.

The objective of this Phase II program is to achieve a commercial solar blind AlxGa1-xN based p-i-n ultraviolet (UV) photodetector product, with high solar blindness, high external quantum efficiency and low dark currents. The Phase II work will buildupon the results obtained from the completed Phase I project, which showed the feasibility of the proposed lateral epitaxial overgrowth approach to ...

High performance infrared detectors with cutoff wavelength above 16 micrometers are highly needed for many applications such as early detection of long range missiles, pollution monitoring, and astronomy. Currently available detectors with high quantumefficiency and high uniformity in this wavelength range are extrinsic silicon detectors which have to be cooled below 10K. Here, we propose novel te ...

Scheduling is a complex, NP-hard problem that challenges the use of any single solution technique. In Phase I, we built a model that uses our multi-technique Quantum Leap Problem Solving Engine to solve a representative but simplified version of the AirForce Satellite Control Network (AFSCN) contact scheduling problem. The system demonstrated that it could schedule the hundreds (500 to 600) of t ...
