PURPOSE: A rotor blade having a projected trailing edge is provided to reduce intensity of vortex generating in the end by comprising a leading edge protrusion part projected to a rotation direction and a trailing edge protrusion part projected to a reversed rotational direction. CONSTITUTION: A rotor blade(100) comprises a main body part(13), a leading edge protrusion part(14), and a trailing edge protrusion part(15). The main body part is coupled to a rotary shaft to have a shape that is extended toward a rotational radius direction of the rotary shaft, and comprises a leading edge(11) and a trailing edge(12). The leading edge is the edge of the rotational direction. The trailing edge is the opposite edge of the rotational direction. The leading edge protrusion part is arranged in the leading edge of the main body part and is projected to the rotational direction. The trailing edge protrusion part is arranged in the trailing edge of the main body part and is projected from a reversed rotational direction. |
