  • Anti-icing core inlet stator assembly for a gas turbine engine
    Patent number: 11391205
    Abstract: A gas turbine engine is defined wherein the inlet guide vanes leading into a core engine flow path are sized and positioned such that flow paths positioned circumferentially intermediate the vane are sufficiently large that a hydraulic diameter of greater than or equal to about 1.5 is achieved. This will likely reduce the detrimental effect of icing.
    Type: Grant
    Filed: December 4, 2015
    Date of Patent: July 19, 2022
    Assignee: RAYTHEON TECHNOLOGIES CORPORATION
    Inventors: Matthew R. Feulner, Shengfang Liao
