  • Method of making a leading edge structure of aircraft airfoil
    Patent number: 6279228
    Abstract: A leading edge structure of an aircraft airfoil comprises an outer skin, a front wall extended in the spanwise direction of the leading edge structure in a front section of the space defined by the outer skin so as to form an anti-icing duct together with a front part of the outer skin, and a plurality of ribs disposed in the space defined by the outer skin so as to form hot air passages. A laminar structure is formed by superposing upper and lower sheets of a superplastic titanium alloy, inserting a pair of core sheets of a superplastic titanium alloy between the upper and the lower sheet, and forming release agent layers in predetermined regions between the sheets.
    Type: Grant

    Date of Patent: August 28, 2001
    Assignee: Fuji Jukogyo Kabushiki Kaisha
