  • Gas turbine blade
    Patent number: 11927109
    Abstract: The present invention relates to a blade for a gas turbine, in particular of an aircraft engine, having a blade airfoil, which has a blade-root-side first profile section and a blade-tip-side second profile section, which is spaced apart from the first profile section in a radial direction, from the first profile section to the second profile section, by a blade airfoil height, wherein a stagger angle of the blade airfoil changes with a height in the radial direction over the first profile section at least over certain portions, wherein, in a first region between a first height and a second, greater height, the change in the stagger angle over the height does not decrease with increasing height at least over certain portions.
    Type: Grant
    Filed: December 8, 2020
    Date of Patent: March 12, 2024
    Assignee: MTU Aero Engines AG
    Inventors: Sergio Elorza Gomez, Tobias Froebel, Nina Wolfrum, Sebastian Mann
