  • Patent number: 9695695
    Abstract: A turbojet fan blade in which a leading edge presents a sweep angle greater than or equal to +28° in a portion of the blade that is situated at a radial height lying in a range of 60% to 90% of a total radial height of the blade measured from its root towards its tip, and the leading-edge sweep angle presents a difference of less than 10° between a minimum sweep angle measured at a radial height of minimum sweep angle situated in the portion of the blade lying in a range of 20% to 90% of the radial height of the blade, and a sweep angle measured at a radial height that is 10% greater than the radial height of minimum sweep angle.

  • Patent number: 8317482
    Abstract: A turbomachine blade including a plurality of blade sections stacked along a radial axis is disclosed. The projection of a line interconnecting the leading edges of the blade sections of the bottom stack onto a mid-plane presents a first longitudinal angle of inclination towards the leading edge that lies in the range 10° to 25°. The projection of a line interconnecting the leading edges of the blade sections of the intermediate stack presents a second longitudinal angle of inclination towards the trailing edge lying in the range 10° to 25°. The projection of a line interconnecting the leading edges of the blade sections of the top stack presents a third longitudinal angle of inclination towards the trailing edge lying in the range 20° to 50°. The bottom limit of the intermediate stack of the blade sections lies in the range 30% to 40% of the total radial height of the stack of blade sections.
