Abstract: An airfoil includes an airfoil body that has a trailing edge region. The trailing edge region includes first and second monolithic ceramic exterior walls, a flow discharge passage between the first and second monolithic ceramic exterior walls, a ceramic matrix composite (CMC) liner at least a portion of which is disposed in the flow discharge passage between the first and second monolithic ceramic exterior walls, and an array of pedestals disposed in the flow discharge passage. Each of the flow guides bridges the CMC liner and at least one of the first and second monolithic ceramic exterior walls.

Abstract: A method for thermally-sensitive coating analysis of a component includes imaging the coated, exposed component over a range of distinct frequencies as selected by a narrowband variable filter; estimating parameters of non-uniformity correction (NUC) for every pixel at every wavelength; constructing a 2D temperature map on a pixel-by-pixel basis using the non-uniformity correction; and mapping the 2D temperature map to a 3D computer aided design (CAD) model.

Abstract: A nondestructive multispectral vibrothermography inspection system includes a fixture to retain a component, an ultrasonic excitation source directed toward the component retained within the fixture, a laser Doppler vibrometer directed toward the component retained within the fixture, and a multispectral thermography system directed toward the component retained within the fixture. A method for nondestructive multispectral vibrothermography inspection of a component, includes generating ultrasonic excitations in a component over a broad range of frequencies; determining a spectral signature in the component from the excitations; comparing the spectral energy signature against database 270 of correlations between vibrational frequencies of a multiple of components and the spectral energy distribution thereof, and classifying the component based on the database data.

Abstract: A aerodynamic particle separator for an Additive Manufacturing System (AMS) has an air supply device to entrain a mixed powder in an airstream flowing through a housing. Each particle in the mixed powder is imparted with a momentum dependent upon the particle weight and size. Utilizing this momentum characteristic, the heavier particles are capable of crossing streamlines of the airstream at a bend portion of the housing and the lighter particles generally stay within the streamlines. Utilizing this dynamic characteristic, the particles of specific weight ranges are collected through respective offtake holes in the housing and controllably fed to a spreader of the AMS.

Abstract: A monolithic composite turbine component includes at least one first region of a first material and one second region of a second material formed by solid freeform fabrication (SFF). The first material may be a metal and the second material may be a ceramic or a ceramic matrix composite. Transition regions between the metal region and ceramic region are functionally graded regions to minimize internal stress during temperature fluctuations.
