  • Propeller, flying object, and method for manufacturing propeller
    Patent number: 12054248
    Abstract: A propeller includes a plurality of blades that extends outward in a radial direction of a rotation central axis relative to the rotation central axis, and includes an end that is located on an opposite side of the rotation central axis. Each of the plurality of blades has a maximum angle of elevation in a position ranging from 30% to 60% with the rotation central axis as a starting point of a radius of a circle that passes through the end of each of the plurality of blades with the rotation central axis as a center, the maximum angle of elevation being a maximum of an angle of elevation in each of the plurality of blades. A change in the angle of elevation in a longitudinal direction of each of the plurality of blades is within 10 degrees per 5% of the radius.
