  • Publication number: 20220196398
    Abstract: An automated method, computer program product and device for determining a thickness of an object at a specific location, such as the determination of a wall thickness of a blade or a vane of a gas turbine. The method includes performing a plurality of ultrasonic measurements around the specific location with an ultrasonic probe of the ultrasonic measurement device, recording and storing the measurement signals, determining at least one apparent thickness of the object for each measurement, sorting the apparent thicknesses in a histogram, and determining the thickness of the object by selecting the most frequently occurring apparent thickness in the histogram.

  • Publication number: 20190048737
    Abstract: A turbine blade for a turbomachine, having a blade airfoil with a blade tip region and a sealing region which has an auxetic material and is arranged and designed such that, when transitioning from a rest state to an operating state of the turbine blade, the blade tip region of the turbine blade expands in a first direction perpendicular to a longitudinal axis of the blade airfoil. An auxetic material is used for a turbine blade for sealing a gas path during operation of a turbomachine.

  • Publication number: 20180238679
    Abstract: A method for predetermining a thickness of a coating which is to be arranged on a substrate is provided. A spray spot is arranged on a surface of the substrate or a test substrate. The volume of the spray spot is determined, and based on the determined volume, the thickness of a layer which is to be applied is worked out. An arrangement for predetermining the thickness of a coating is further provided.

  • Publication number: 20140099476
    Abstract: A method for additive manufacturing with multiple materials. First (48), second (50), and third (52) adjacent powder layers are delivered onto a working surface (54A) in respective first (73), second (74), and third (75) area shapes of adjacent final materials (30, 44, 45) in a given section plane of a component (20). The first powder may be a structural metal delivered in the sectional shape of an airfoil substrate (30). The second powder may be a bond coat material delivered in a sectional shape of a bond coat (45) on the substrate. The third powder may be a thermal barrier ceramic delivered in a section shape of the thermal barrier coating (44). A particular laser intensity (69A, 69B) is applied to each layer to melt or to sinter the layer. Integrated interfaces (57, 77, 80) may be formed between adjacent layers by gradient material overlap and/or interleaving projections.

  • Publication number: 20120156362
    Abstract: A method for generating a motion path for a spray gun for coating a component is disclosed. Path templates for surface segments of the component are defined, the surface is analyzed, a first motion path is generated, a model of the spray profile is simulated, the coating thickness is simulated for the motion path based on the simulated model of the spray profile and the generated first motion path. The simulated coating thickness is compared with tolerances and when the simulated coating thickness does not achieve the tolerances, an adapted motion path is generated. The coating thickness is simulated for the motion path based on the simulated model of the spray profile and the generated adapted motion path. Repeating the comparing, the motion path generation, and the simulation of the coating thickness based on the generated adapted motion path until the simulated coating thickness achieves the tolerances.
