  • Component shielding
    Patent number: 11560798
    Abstract: A method of manufacturing a component for a gas turbine engine includes applying a thermoplastic polymer sheet over a composite body for the component; applying a shield over part of the composite body, the shield terminating at an end which overlies the thermoplastic polymer sheet and defines an interface between shielded and unshielded regions of the component; and pressing the shield into the thermoplastic polymer sheet so that the thermoplastic polymer sheet deforms around the end of the shield, such that the exterior profile of the component at the interface between the shielded and unshielded regions is flush.
    Type: Grant
    Filed: September 30, 2019
    Date of Patent: January 24, 2023
    Assignee: ROLLS-ROYCE PLC
    Inventors: David Churcher, Andrew R. Collis

  • Automated welding apparatus and computer-implemented method for filing a volume
    Patent number: 10427238
    Abstract: An automated welding apparatus and computer-implemented method are described which generally perform the steps of: scanning a joint interface of a workpiece using a three-dimensional scanner (S4); determining a volume to be filled by a welding process (S6); determining a specification for the welding process based on the volume to be filled using an algorithm (S8, S10); and controlling a welding device so as to execute the specification by moving the welding device relative to the workpiece (S12).
