Abstract
An aircraft turbojet fan including multiple fan blades including a support that includes a rear portion including a first surface located on an intrados side and a second surface located on an extrados side. A fan disk includes, between recesses, attaching flanges radially protruding towards the outside such that the first surface and the second surface are located respectively opposite two attaching flanges. The fan further includes a wear-resistant part installed on the blade to form a protective shell on each of the first and second surfaces of the support, preventing contact between each surface and the attaching flange located opposite it.
