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.

Abstract: The present invention relates to the field of blades, particularly fan blades, intended for turbojets, particularly of the aeronautical type. Its objective is to provide a fan blade the features of which will enable the number of fan blades to be reduced while at the same time providing satisfactory performance. According to the invention, the fan blade comprises a plurality of aerodynamic parts which are superposed in a radial direction Z and the number of aerodynamic profiles varies from one aerodynamic part to the other.
