PROPELLER BLADE FOR TURBO ENGINE

摘要

The invention relates to a propeller blade (34) extending radially between a blade root (38) and a blade tip (36) and having a leading edge (40) and a trailing edge (42), together with a pressure side face and a suction side face. According to the invention, along the leading edge (40), the angle (α) between the radial direction and a tangent to the leading edge passes through a local maximum zmax situated in the range 60% to 80% of the height of the blade (34). Furthermore, the suction side face of the blade (34) includes an indentation (54) extending axially from the leading edge (40) to the trailing edge and located at a height of the blade (34) between the local maximum zmax and the blade tip (34).
