A cutting-wing rotor shape of a picking drone

Abstract

The invention relates to a rotor shape with a cutting airfoil for a picking unmanned aerial vehicle, including a blade shape and a cutting airfoil; the blade shape sequentially includes a cutting section, a transition section, a main lift section and a root reinforcement section, and the cutting section is a blade 100%-80% of the span direction, the blade twist angle of the cutting section is 0°, the windward side of the blade along the 100%-80% of the span direction of the cutting section is a gradually expanding structure, and the airfoil of the cutting section is a cutting wing type; the transition section is 80%-70% of the span of the blade, the blade twist angle of the transition section transitions from 0° to 5°, and the airfoil of the transition section transitions smoothly from the cut airfoil to the standard airfoil; the main lift section is 70%-40% of the blade span, the airfoil of the main lift section is a standard airfoil, and the shape of the main lift section is a 16% standard airfoil; the root reinforcement section is 40%-10% of the 4 span, and the main The shape of the lift section transitions from 16% standard airfoil to 24% standard airfoil, and the windward side of the root reinforcement section along the direction of 40%-10% of the span is a tapered structure; the joint area between the blade and the hub is spanwise 10%‑0%; cutting airfoils are provided with cutting edges at the leading edge of the airfoil.

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...
