This project will investigate candidate space-time coding schemes to be incorporated in a multiple-input multiple output two-way communication system that operates within an urban warfare environment. The main objective is to increase channel capacity to achieve high-quality video transmission using narrow signal bandwidths, typically deployed for voice channels. The investigation will determine t ...

Advanced Cooling Technologies, Inc. (ACT), supported by Hamilton Sundstrand, proposes to develop a shock and vibration tolerant Capillary Two-Phase Loop for military vehicle applications. The proposed capillary two-phase loop differs from the traditional loop heat pipes and capillary pumped loops in the evaporator design, which provides inherent tolerance to shock and vibration. Two additional fea ...

The objective of this proposal is to demonstrate the feasibility of producing exchange-coupled magnets with a mixture of Sm2Fe17Nx and alpha double prime-iron nitride powders as starting materials. Advanced Materials Corporation (AMC), together with Georgia Institute of Technology propose to produce these powders with the use of a fluidized bed reactor and consolidate mixtures of these powders uti ...

A complementary, theoretical and experimental effort to design and verify high-lift, low pitching-moment airfoils for VTOL UAVs is proposed. In Phase I, an accurate, rapid, test capability will be validated over the range of Reynolds numbers from 50,000 to 500,000 by investigating the E 387 airfoil, the low Reynolds number calibration standard, in The Pennsylvania State University Low-Speed, Low- ...

Though ladar and stereo have received far more attention for UGV navigation use, radar offers some unique benefits. Many radar systems have the ability to partially penetrate thin vegetation, fog, smoke, and other obscurants while detecting hidden solid obstacles. Also, some systems provide useful information in addition to range; for example, Doppler radars measure target relative velocities as w ...

In the proposed work we will investigate the THz properties of a slab waveguide made from a GaP or ZnGeP2 wafer. We plan to investigate how the width of a slab waveguide will affect the output power of the THz waves and normalized conversion efficiencies. We are particularly interested in the exploration of how the multi-modes supported by the waveguide will affect the THz parametric conversion du ...

New technologies for assessing how blending affects structural and aerodynamic mistuning will be developed using the combined strengths of Blade Diagnostics Corporation and Duke University. BDC has developed an approach for identifying aerodynamic mistuning from engine data that will be further developed under this STTR. Duke will develop new methods for computing the effect of blending on the a ...

Due to funding and scheduling limitations, current testing for different IBR damping techniques and treatments has been forced to be accomplished simultaneously on a single IBR. Just like IBRs in service, the rotors are mistuned and the modal response is highly coupled. Mistuning refers to the fact that slight manufacturing differences cause each blade to have a different natural frequency – t ...

For this Phase I STTR program, TRS proposes to investigate the synthesis of new single crystal piezoelectric compositions that will operate at higher temperature, higher electric field and/or higher stress than current state-of-the-art PMN-PT single crystals. PMN-PT single crystals are readily available for certain applications, however a broader operating range would allow for greater device des ...

For the proposed work, TRS Technologies, Inc., in collaboration with The Penn State Electro-optics Center (EOC), and Dr. David J. Quesnel at the University of Rochester will investigate increasing the yield of damage minimized or damage free piezoelectric single crystals by establishing an optimal parameter matrix for PMN-PT crystal machining involved in wafer and element processing (slicing, lapp ...
