    Date of Patent: October 27, 2020
    Assignee: Rolls-Royce Corporation
    Inventors: Kerry J. Lighty, Larry A. Junod
  • Patent number: 10267177
    Abstract: A rotor system lock for a gas turbine engine is described which blocks movement of rotating wheel assemblies relative to static vane assemblies in a gas turbine engine in order to block unintended rotation (or windmilling) of the gas turbine engine when it is exposed to high winds while at rest or to ram air during pre-launch flight and thereby avoid damage to components of the engine.

  • Patent number: 9845688
    Abstract: A gas turbine engine airflow member including a blade core portion, a shroud tip portion extending from the blade core portion, and an airfoil portion formed exteriorly to the blade core portion, where the blade core portion and the shroud tip portion are constructed as a first unitary structure and the airfoil portion is constructed as a second structure. A method of forming a gas turbine engine component is also disclosed.

  • Patent number: 5195243
    Abstract: A coated porous metal panel includes a first outer surface on one side of the panel, a second outer surface on the other side of the panel, a plurality of laterally offset discharge and inlet pores in respective ones of the first and the second outer surfaces, an internal chamber in the panel communicating with each of the inlet and discharge pores so that tortuous gas flow paths are defined through the porous metal panel, and a shield lamina mechanically clamped against the second outer surface. The shield lamina has shield pores aligned with the inlet pores to permit gas flow into the inlet pores. A plurality of extraction passages are formed in the panel between the internal chamber and the second outer surface and directly behind each of the discharge pores. When the coating material is sprayed on the first outer surface with the shield lamina not attached to the panel, surplus coating entering the discharge pores passes through the extraction passages for collection behind the panel.

  • Patent number: 5152667
    Abstract: A cooled wall structure including a hot side, a cold side, a linear slot opening through the hot side, a plurality of diffusion chambers below the hot side separated therefrom by relatively thin bridge sections of the wall structure and arrayed in checkerboard fashion on opposite sides of the linear slot and opening into the linear slot through the sidewalls thereof, and a plurality of passages from the cold side to each of the diffusion chambers. The cold side is exposed to coolant gas under pressure and the passages are aimed at the bridge sections so that jet of cooling gas issuing from the passages impinge against the bridge section for convection cooling the hot side. The bridge sections prevent direct penetration of the coolant gas jets into the environment adjacent the hot side. The coolant gas flows from the diffusion chambers into the linear slots and from the linear slots over the hot side to form on the latter a coolant film or blanket.
