To provide a blade for a propeller that is further improved in propeller efficiency, and to provide a propeller mechanism and a flying object.SOLUTION: A blade 3 for a propeller is used for a flying object 20. The blade 3 comprises an inner blade 4 on a side of a propeller shaft 2 and an outer blade 5 provided on an outside of the inner blade, where a blade angle 23 defined between the inner and outer blades and a rotation surface 22 of the propeller is variable. A suppression mechanism 6 is provided in the vicinity of part in which the outer blade and the inner blade are adjacent to each other. The suppression mechanism suppresses an air flow 30 that comes around to a top surface from a lower surface of the outer blade via an interval between the outer blade and the inner blade.SELECTED DRAWING: Figure 1
【課題】プロペラ効率を一層高めたプロペラの羽根、プロペラ機構および飛翔体を提供することを課題とする。【解決手段】飛翔体20に用いられるプロペラの羽根3であって、羽根3が、プロペラ軸2側の内羽根4およびその内羽根の外側に設けられる外羽根5からなり、内羽根および外羽根のプロペラの回転面22となす羽根角23がそれぞれ可変にされており、外羽根と内羽根の隣り合っている部位の付近に抑制機構6が設けられており、その抑制機構は、外羽根と内羽根の間を介し、外羽根の下面から上面へ回り込む気流30を抑制するものである。【選択図】図1
