    Abstract: A turbine exhaust diffuser (12) for a gas turbine engine having a turbine section, the exhaust diffuser (12) includes a flowpath (14) downstream of the turbine section. The flowpath (14) is defined at least in part by a turbine casing (16) having an inner casing (18) forming an ID flowpath boundary (20) and an outer casing (22) forming an OD flowpath boundary (24). A least one strut (26) is positioned within the flowpath (14) and spans between the inner casing (18) and the outer casing (22). The exhaust diffuser (12) includes an undulating portion (32) located along at least one of the inner casing (18) and the outer casing (22) along the exhaust diffuser (12). The undulating portion (32) includes at least a first point (34) upstream of the at least one strut (26) and a second point (36) approximate to a halfway span of the at least one strut (26). The undulating portion (32) includes radially and axially extending crests (42) and troughs (44).

    Abstract: The invention relates to a computer-implemented method (100) for probabilistic quantification of probability of failure PoF(n) of a component, especially a gas turbine component, which during operation is subjected to cyclic stress, wherein the component is divided virtually in one or more domains, the method comprising the steps of: providing or determining (104) for at least one domain, preferably for each domain, a domain probability density function PDF CI i for crack initiation and providing or determining (106) for the considered domains a domain probability density function PDF CPF I for subsequent crack propagation induced failure. For providing an improved method for probabilistic quantification of a probability of failure of a component, especially a gas turbine component, designated for being subjected to cyclic stress, it is proposed to determine for each considered domain a combined domain cumulative distribution function for failure CDF Fail i or its probability density function PDF Fail i by convoluting either both the considered domain probability density functions PDF CI i for crack initiation induced failure and the respective domain probability density function PDF CPF i for subsequent crack propagation induced failure, or their integral function CDF CI i and CDF CPF i . Alternatively, numerical methods for said component failure probabilities are described including domain-based Monte-Carlo schemes.

    Abstract: Turbine engine (80) components, such as blades (92), vanes (104, 106), ring segment 110 abradable surfaces 120, or transitions (85), have vertically aligned engineered surface features (ESFs) (632, 634) and furcated engineered groove features (EGFs) (642, 652). A planform pattern of EGFs (642, 652) is cut into the outer surface of the component's thermal barrier coating (TBC). The EGF pattern includes a planform pattern of overlying vertices (644) respectively in vertical alignment with an underlying corresponding ESF (632, 634). At least three respective groove segments (642, 652, 642) within the EGF pattern (640) converge at each respective vertex (644) in a multifurcated pattern, so that crack-inducing stresses are attenuated in cascading fashion, as the stress (σ A ) is furcated (σ B , σ C ) at each successive vertex juncture.

    Abstract: A method for probabilistically predicting fatigue life in materials includes sampling (41) a random variable for an actual equivalent initial flaw size (EIFS), generating (42) random variables for parameters (InC, m) of a fatigue crack growth equation [Formula should be inserted here] from a multivariate distribution, and solving (43) the fatigue crack growth equation using these random variables. The reported EIFS data is obtained by ultrasonically scanning a target object, recording echo signals from the target object, and converting echo signal amplitudes to equivalent reflector sizes using previously recorded values from a scanned calibration block. The equivalent reflector sizes comprise the reported EIFS data.
