To further reduce BVI noise in an aircraft.SOLUTION: A rotor blade for an aircraft includes: a blade body that has a blade profile in which undersurface pressure is larger than top face pressure when rotated, and one end of which forms a first blade tip of the rotor blade; and a blade for generating vortex which forms a second blade tip by being provided at the end on a blade tip side of the rotor blade, and has a blade profile in which undersurface pressure is smaller than top face pressure when rotated.SELECTED DRAWING: Figure 1

    【課題】航空機におけるBVI騒音を一層低減させることである。【解決手段】実施形態に係る航空機用のロータブレードは、回転させた場合に上面の圧力よりも下面の圧力の方が大きくなる翼型を有し、一端が前記ロータブレードの第1の翼端を形成するブレード本体と、前記ロータブレードの翼端側における端部に設けられることによって第2の翼端を形成し、回転させた場合に上面の圧力よりも下面の圧力が小さくなる翼型を有する渦発生用のブレードとを有するものである。【選択図】 図1
