  • System and method for image-based structural health monitoring suitable for structures having uncertain load conditions and support conditions
    Patent number: 9734423
    Abstract: An image-based structural health monitoring system and method are disclosed herein. The image-based structural health monitoring system includes a marker image acquisition unit, a marker coordinate calculation unit, a shape function determination unit, and a structural health evaluation unit. The marker image acquisition unit acquires marker images of markers attached onto the surface of a structure. The marker coordinate calculation unit calculates the coordinates of the markers in the marker images. The shape function determination unit determines a shape function by performing spline interpolation based on the calculated marker coordinates. The structural health evaluation unit evaluates the structural health of the structure by calculating the strain or stress of the structure based on the radius of curvature calculated at each location on the determined shape function.

  • Gas turbine device using supercritical fluid as cooling fluid
    Patent number: 9638104
    Abstract: The present invention relates to a gas turbine device using a supercritical fluid as a cooling fluid, the gas turbine device having a compressor for compressing air, a combustor for burning the air emitted from the compressor and fuel, and a turbine driven by the burned gas emitted from the combustor, wherein the gas turbine device includes cooling passages formed in the combustor and the turbine, along which the supercritical fluid as a cooling fluid flows to allow the combustor and the turbine to be cooled.
