An internal aircraft weapons bay, when exposed to freestream flow, experiences an intense aeroacoustic environment and varied suppression concepts have been tested for attenuating flow-induced oscillations. Recent tests with open-loop, high-frequencyexcitation have shown great promise in providing broadband attenuation and elimination of tones. High frequency actuation apparently alters the dyna ...

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 ...

The Phase I efforts aimed at establishing the feasibility of Air Film Damping for controlling vibration induced high-cycle fatigue (HCF) in gas turbine engine components. To establish this goal, current commercially available finite element software wasutilized to develop a methodology for predicting the effects of Air Film Damping on dynamic response of simple components such as beams and plates ...

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 proposed SBIR Phase II effort will build upon the demonstration success of the Phase I effort for the reduction of viable Biological Warfare (BW) agent (stimulant) release from a scaled target structure, concurrent with denial of the use of the BWagent remaining within the target structure to minimize collateral damage potential form the engagement of a threat BW storage facility. The Phase I ...

As we look towards the next decade there are many opportunities to enhance services for navigation which compliment, enhance, and replace existing Aids to Navigation technologies. This Phase II project will continue the US Coast Guard¿s investigation of the development of a Virtual Aids to Navigation system by building a working prototype that delivers real-time data to the mariner. The vATON s ...

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 ...

This proposal outlines a program to develop a complete Stokes polarization imaging system. Although conventional imaging techniques have undergone fairly advanced levels of development, enabling low-level light detection, IR imaging, and high-resolutionimaging all at rapid frame rates, the techniques nevertheless are fundamentally constrained to detection of only the intensity and color of light. ...

We propose to develop software products for embedded, real-time monitoring of machinery health and failure prediction. The work will be based on new damage estimation, tracking, and prognostic algorithms that have been successfully developed in Phase I.Existing algorithms have been applied to data from the Boeing Reconfigurable Control and Fault and Identification System (RCFIS), an F/A-18 stabil ...
