Propeller blade and method for repairing a propeller blade

Abstract

The invention relates to a propeller blade for an aircraft propeller, comprising a wi¬ng section (10) and a propeller blade root (20) connected thereto, as well as a method for repairing such a propeller blade. The wing section (10) may have a foam and / or honeycomb core (11, 12, 13) with a sheath (14) made of a fiber-reinforced polymer material. The propeller blade root (20) may be made of a metallic material and may have a shaft (21) extending into and connected to the wing section (10), at least one outer bearing ring (23), and an adjustment pin (22). It is preferred that the bearing ring (23) has a running surface consisting of a layer (26) of a steel material welded or remelted onto the bearing ring (23), which has a yield strength Rp0.2 of over 750 N / mm² and a tensile strength Rm of over 1,000 N / mm². The bearing ring (23) with the running surface can have a core Vickers hardness HV10 of over 430. (Figure 2)
