Composite turbomachine blade with metal reinforcement

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,
• a first end of the at least one recess opens out to an aperture through a suction side of the blade,
• a second end of the least one recess, opposite the first end of the at least one recess, terminates within the solid metal reinforcement, and
• the at least one recess is not in fluid communication with an aperture on the pressure side of the blade, an aperture on the leading edge of the blade, an aperture on the root of the blade, or an aperture on the tip of the blade.
