摘要： The invention relates to an arrangement of a component (2, 20), which comprises at least one control device (3) for detecting a degradation (40) of the component, whereby the control device comprises at least one electrical conductor structure (30) and the component and the conductor structure of the control device are connected to each other in such a manner that the degradation of the component effects a degradation (41) of the conductor structure. The arrangement is characterized in that the control device comprises at least one means for examining a time domain behavior of the conductor structure. The invention also relates to a method for examining operability of a component using the aforementioned arrangement. The inventive method comprises the following steps: a) feeding the input signal to the conductor structure, b) reading out the output signal from the conductor structure, and c) evaluating the measured signal. The invention is especially used for the operational check of a heat shield (20) of the combustion chamber of a gas turbine.

摘要： The invention relates to a configuration (1) of a component (2) and at least one test device for recording a degradation (4, 40) of said component. Said test device has at least one electric oscillating circuit (31) and the component and oscillating circuit are interconnected in such a way that the degradation of the component causes a degradation (41) of the oscillating circuit and a modification of a detectable resonant signal of the oscillating circuit. The configuration is characterised in that the test device has at least one additional oscillating circuit (32) comprising an additional detectable resonant signal and that the oscillating circuit and the additional oscillating circuit are coupled to form a comprehensive oscillating circuit (30) comprising a detectable comprehensive resonant signal that differs from the resonant signal and the additional resonant signal. The inventive component is for example a heat shield (20) of a combustion chamber in a gas turbine. The oscillating circuits are connected in parallel. Different high-frequency signals are received for an intact oscillating circuit and for a degraded oscillating circuit. The oscillating circuit consists of a brittle ceramic conductive material. A crack (degradation) in the heat shield continues as a crack in the oscillating circuit. The measuring signal received permits the degradation of the component to be reliably detected.

摘要： Turbine engine (80) components, such as blades (92), vanes (104, 106), ring segment 110 abradable surfaces 120, or transitions (85), have furcated engineered groove features (EGFs) (403, 404, 418, 509, 511, 512) that cut into the outer surface of the component's thermal barrier coating (TBC). In some embodiments, the EGF planform pattern defines adjoining outer hexagons (560, 640, 670, 690, 710). In some embodiments, the EGF pattern further defines within each outer hexagon (560, 640, 670, 690, 710) a planform pattern of adjoining inner polygons (570, 580, 590, 600, 610, 680, 682, 700, 702, 704, 705, 720). At least three respective groove segments (509, 511, 512) within the EGF pattern (506, 507, 508) converge at each respective outer hexagonal vertex (510, 564) or inner polygonal vertex (574, 564, 604, 614) in a multifurcated pattern, so that crack-inducing stresses are attenuated in cascading fashion, as the stress (σA) is furcated (σB, σC) at each successive vertex juncture.
