Combustion chemical vapor deposition (CCVD), which was invented by the principal investigator, is the only open atmosphere CVD technique for ceramics and metals. The CCVD method has been shown to inexpensively and quickly apply dense, adherent, epitaxial thin films in a continuous manner. This technology can be used for the production of thermal control coatings onto spacecraft even after assemb ...

The project objective are to develop a new software method for the dynamic analysis of aircraft and to prove the potential of unique high angle of attack Leading Edge Vortex Control (LEVC) devices. The software method will be an upgrade of a current computer code. The upgrade will include the effects of hysteresis during dynamic stall. New methods recently published employing state-spac ...

The xpatch code suite, today combines a highly regarded high-frequency RCS prediction code with several visualization tools and a host of CAD editing and conversion programs. Currently, ideal conditions are always assumed by xpatch. In reality, sensor characteristics and atmospheric effects play a part in the appearance of a collected signature. In this proposal, we outline a course fo ...

The use of synthetic data for the generation of target signature templates is a vital element of current and future automatic target recognition systems. [1] [2] Although current synthetic signatures closely match their measured counterparts, they suffer from two shortcomings: 1) susceptibility to model error and 2) poor representation of signature variance. The current model validation relie ...

ALGORITHMS WILL BE DEVELOPED FOR THE AUTOMATED DESIGN OPTIMIZATION OF PHYSICAL SYSTEMS (MODELS) GOVERNED BY PARTIAL DIFFERENTIAL EQUATIONS (PDE'S) IN TWO AND THREE DIMENSIONS. THE IMMEDIATE MOTIVATION IS THE PROBLEM OF ELECTRODE DESIGN OPTIMIZATION FOR LASERS AND SWITCHES. THIS WORK WILL BUILD ON THE ELF CODES, USER-INTERACTIVE DESIGN CODES WHICH ACCURATELY CALCULATE THE FIELDS IN LASERS AND PULSE ...

AN EFFICIENT ARCHITECTURE WILL BE DESIGNED FOR THE PHASING, EXCITATION, CONTROL, AND CALIBRATION OF A LARGE SPACE BASED ARRAY. IT IS PROBABLE THAT SIGNAL DISTRIBUTION WILL BE BY CLOSED OR OPEN OPTICAL PATHS. PHASING MAY BE BY DIRECT DIGITAL AT LOW FREQUENCIES, ACOUSTICAL LENSES AT MIDDLE FREQUENCIES, AND CONVENTIONAL PHASESHIFTERS AT HIGH FREQUENCEIS. RF EXCITATION DISTRIBUTION WILL BE BY CLOSED O ...

TWO OR MORE FREQUENCY HOP RADIOS OPERATING IN A COMMON SITE CREATE A SUBSTANTIAL INTERFERENCE PROBLEM BECAUSE CONVENTIONAL FIXED FILTERING TECHNIQUES WITHOUT FREQUENCY AGILITY CANNOT BE USED TO SUPPRESS IT. A NEW ENABLING TECHNOLOGY CALLED ACOUSTIC CHARGE TRANSPORT (ACT) HAS GIVEN RISE TO A FAMILY OF PROGRAMMABLE FILTERS THAT HOLD PROMISE FOR REDUCING THIS INTERFERENCE PROBLEM. THE PROGRAMMING TIM ...

The fabrication of large format, long wavelength (LWIR) mercury cadmium telluride based focal plane arrays (FPAs) is highly desirable for Air Force applications such as satellite power and array cooling reduction along with higher resolution. However, the development of large FPAs has been seriously impeded by the limited size of commercially available bulk Cd{sub 1-x}Zn{sub x}Te substrates. In ...
