Rotor wing model with cutting wing type of picking unmanned aerial vehicle

Abstract

The invention relates to a rotor wing model with a cutting wing type of a picking unmanned aerial vehicle. The rotor wing model comprises a paddle model and the cutting wing type, wherein the paddle model sequentially includes a cutting section, a transition section, a main lift section and a root reinforcing section, the cutting section is 100%-80% of a span direction of a paddle, a paddle torsion angle of the cutting section is 0 degree, a windward side of the paddle, in the 100%-80% direction of the span direction, of the cutting section is a diverging structure, and the wing section of thecutting section is a cutting wing section; the transition section is 80%-70% of the span direction of the blade, the blade torsion angle of the transition section is transited from 0 degree to 5 degrees, and the wing section of the transition section is smoothly transited from a cutting wing section to a standard wing section; the main lift section is 70%-40% of the span direction of the blade, the wing section of the main lift section is a standard wing section, and the shape of the main lift section is a 16% standard wing section; and a root reinforcing section is 40%-10% of the four spanwise directions, the main lift section is in the shape of a 16% standard wing section transited to a 24% standard wing section, and the windward side of the root reinforcing section in the 40%-10% spandirection is a gradually-contracted structure. A butt joint area of propeller blades and a propeller hub is 10%-0% of the span direction; and a cutting edge is arranged at the wing type front edge ofthe cutting wing type.

Description

technical field [0001] The invention relates to the technical field of rotor blade design, in particular to a cutting-wing rotor shape of a picking drone. Background technique [0002] The blades currently used by small multi-rotor UAVs only provide flight aerodynamic force and do not provide other functions. [0003] The cutting tools used in gardening and agriculture and forestry have cutting bodies that only have a cutting function and do not take into account other functions. [0004] At present, the high-altitude branch cutting in the garden and agriculture industry can only rely on manual climbing to the height of the tree crown, and then the cutting operation is low in efficiency and high in risk, especially in mountainous planting areas where transportation is inconvenient and large machinery is difficult to reach. Casualties happen from time to time. Contents of the invention [0005] The technical problem to be solved by the present invention is to overcome the...
