  • Gas turbine engine cooling fluid metering system
    Patent number: 11939919
    Abstract: A fluid supply system for a gas turbine engine includes a first component and a second component. A fluid fitting has a fluid junction. The fluid junction includes a first fluid port in fluid communication with and configured to supply a first cooling fluid to the first component. The fluid junction includes a second fluid port in fluid communication with and configured to supply a second cooling fluid to the second component. A primary pipe is fluidly connected to the fluid fitting. A flow meter is arranged upstream from the fluid junction and is configured to receive a cooling supply fluid from a fluid source. Thee flow meter is a wall having an orifice and a surface that is radiused and convex facing into the cooling supply fluid. A secondary pipe is secured to the fluid fitting and is configured to supply the second cooling fluid to the second component. A turbine section includes the first and second components.

  • Engine mid-turbine frame transfer tube for low pressure turbine case cooling
    Patent number: 10087782
    Abstract: A turbine engine includes a turbine section with a low pressure turbine and a turbine case disposed about an axis. A frame assembly defines an outer cavity and an inner cavity with the outer cavity including at least one opening configured and adapted to communicate cooling air to the turbine case. A transfer tube is disposed within the outer cavity and is configured and adapted to receive cooling air. The transfer tube includes a bend configured to impart circumferential velocity to the cooling air within the outer cavity.
