  • Publication number: 20250060206
    Abstract: An inspection device is disclosed herein. In various embodiments, the inspection system device comprises: a support structure; a motor; a shaft operably coupled to the motor, the shaft extending from a first side of the support structure to a second side of the support structure, the shaft configured to couple to a bladed rotor; and a scanner moveably coupled to the support structure, the scanner configured to generate a three-dimensional model for the bladed rotor.

  • Patent number: 11860060
    Abstract: A method of repairing an integrally bladed rotor (IBR) may comprise: performing a vibratory analysis of a rotor module including a first inspected IBR with a potential repair shape for the IBR; determining an undesirable vibratory characteristic of a second inspected IBR in the rotor module; iterating the potential repair shape for the first IBR to eliminate the undesirable vibratory characteristic of the second inspected IBR; and repairing the first IBR with a selected repair shape based on determining the potential repair shape eliminates the undesirable vibratory characteristic.

  • Publication number: 20230315938
    Abstract: A method is providing comprising receiving, via a processor, a digital representation of a potentially repaired blade from an inspection system, the digital representation including a repair blend profile, the digital representation based on an inspected blade of an inspected bladed rotor; generating, via the processor, an airfoil definition file corresponding to the digital representation, inputting, via the processor, the airfoil definition file into an aerodynamic simulator, receiving, via the processor, simulation results from the aerodynamic simulator of the potentially repaired blade; analyzing, via the processor, an overall engine impact of the potentially repaired blade based on the simulation results, inputting, via the processor, a plurality of simulation results into an aerodynamic effect translator, and receiving, via the processor, a translated impact for local effect of a repaired bladed rotor with the potentially repaired blade.

  • Patent number: 10253693
    Abstract: A single, unitary thermal management system (TMS) manifold for a gas turbine engine is provided which comprises one or more interfaces for mounting various thermal management system components directly to the TMS manifold. The TMS manifold also defines fluid passages for transferring fuel, engine lubricant or generator oil from one component to another component. Packing numerous fuel system and lubricating system components within the TMS manifold reduces cost and weight and simplifies maintenance.
