  • Publication number: 20220214260
    Abstract: A tomography duct for wind tunnels includes a plurality of light sources and sensors displaced around a support structure. The light sources are cycled and sensor measurements are made from sensors opposite the light sources. Tomographic algorithms are used to determine an extinction map from the sensor measurements. The extinction map provides details about particles in a cross-section of the air flow through the tomography duct.
    Type: Application

  • Publication number: 20160011105
    Abstract: Systems and methods for imaging and detection of small liquid and solid water particles in different spray conditions includes visible light laser diodes that are pulsed across the area of interest and optical detectors that measure the extinction of light intensity at different directions. The attenuated light projections across the field of view are reconstructed to yield an image of the particles that crossed the plane of light. A wind tunnel is a major tool used in understanding of ice formation and the performance of aircraft engine components. The measurement of the spray provides calibration and, to date, wind tunnel calibration has been time consuming and expensive. This system and method provide near real-time in-situ quasi-quantitative full-field ice/water content data and the corresponding reconstructed images for analysis. The support frame, source-detector configurations, acquisition, simulation, and reconstruction methods of the light emission tomography technology are also disclosed.

  • Patent number: 8939253
    Abstract: Systems and methods for the suppression of unwanted noise from a jet discharging into a duct are disclosed herein. The unwanted noise may be in the form of excited duct modes or howl due to super resonance. A damper member is used to reduce acoustic velocity perturbations at the velocity anti-node, associated with the half-wave resonance of the duct, weakening the resonance condition and reducing the amplitudes of the spectral peaks.
