  • Propeller
    Publication number: 20260071546
    Abstract: A propeller. The blade thrust surfaces of the propeller correspond to the surface of a cone, and the hub axis is set at an angle relative to a first generator line of the cone which passes through the hub axis and a second generator line of the cone which passes through the blade thrust surface to achieve desired gamma angles over the blade thrust surface. A propeller whose blade center axis does not conform to a generator line of a cone also is disclosed.

  • Propeller
    Patent number: 12497892
    Abstract: A propeller. The blades of the propeller are characterized by a blade center axis which corresponds to a generator line of a cone to which the blade, or blade thrust surface, conforms. The propeller hub is fixed to the blade at the root, in line with the blade center axis, such that the hub axis and blade center axis lie in the same plane, and the leading edge of the blade is positioned forward (referring to the upstream direction of movement caused by the propeller) of the trailing edge of the blade.
