Zusammenfassung:PURPOSE: A rotor blade to reduce a vortex ring including a trailing edge is provided to reduce or to remove the vortex ring by discharging the compressed air to the outside of the rotor blade. CONSTITUTION: A rotor blade to reduce a vortex ring comprises a housing, a leading edge(112), and an air flow channel. The reading edge makes up a part of the housing. An injection hole(112-2) is formed at a leading edge. The air flow channel is connected to the air inducing cavity the air flowed in through the air injection hole in the rotor blade rotation. The air flow channel is formed inside the housing along the longitudinal direction of the rotor blade. The end part of the air flow channel is opened to the outer end of the housing.
