  • System and methods for controlling surge margin in the compressor section of a gas turbine engine
    Patent number: 11519339
    Abstract: Systems and methods are disclosed for controlling surge margin in the compressor section of a gas turbine engine. A first compressor section and a second compressor section are in fluid communication with a bypass conduit. An auxiliary turbine and discharge conduit are positioned in the bypass conduit. Fluid flow from the compressor sections into the bypass conduit is controlled by bypass control valves.
    Type: Grant
    Filed: October 5, 2021
    Date of Patent: December 6, 2022
    Assignee: Rolls-Royce North American Technologies Inc.
    Inventors: Benjamin Michael Iwrey, Graham Adam Burkholder

  • Systems and methods for controlling surge margin in the compressor section of a gas turbine engine
    Patent number: 11168619
    Abstract: Systems and methods are disclosed for controlling surge margin in the compressor section of a gas turbine engine. Bypass ports on a first compressor section and second compressor section lead to a bypass conduit. An auxiliary turbine and discharge conduit are positioned in the bypass conduit. Fluid flow from the compressor sections into the bypass conduit via the bypass ports is controlled by bypass control valves.
