Abstract:
1. A turbomachine blade comprising: an aerodynamic surface extending along a first direction between a leading edge and a trailing edge, and extending along a second direction substantially perpendicular to the first direction between a root and a tip of the blade, said aerodynamic surface being made of a composite material; and a solid metal reinforcement adhesively bonded to the leading edge of the aerodynamic surface, wherein: the solid metal reinforcement extends along the first direction beyond the leading edge of the aerodynamic surface of the blade and extends in the second direction between the root and the tip of the blade, the solid metal reinforcement includes at least one recess for absorbing at least a portion of an energy that results from an impact of a foreign body against the leading edge of the blade, the at least one recess extends substantially along a third direction perpendicular to both the first direction and the second direction, and the at least one recess opens out to both an aperture through the pressure side of the blade and an aperture through the suction side of the blade.
