Abstract
The utility model discloses a light high-strength hollow propeller which comprises a central connection part connected to a motor output shaft and two propeller blades symmetrically extending on the two sides of the central connection part, wherein each propeller blade is an internally-hollow carbon fiber blade, and a carbon fiber strip for enhancing the strength of the propeller blade is arranged in a hollow cavity of the propeller blade. The utility model aims at providing a light high-strength hollow propeller.
Description
Technical field
The utility model relates to a kind of lightweight, high strength, hollow screw oar.
Background technology
Existing unmanned vehicle screw propeller quality is large, affects the flight time of aircraft.For this reason, be badly in need of wanting a kind of lightweight, high strength, hollow screw oar, the application creates under such background.
The utility model content
The utility model purpose is in order to overcome the deficiencies in the prior art, a kind of lightweight, high strength, hollow screw oar to be provided.
The purpose of this utility model is achieved through the following technical solutions:
Lightweight, high strength, hollow screw oar, it comprises the center connecting portion that is connected on the motor output shaft, and the symmetrically arranged two screw propeller fins that extend to both sides from the center connecting portion, the screw propeller fin is the fine fin of the carbon of inner hollow, is provided with the fine bar of the carbon of strengthening screw propeller fin intensity in the cavity of screw propeller fin.
Examples of implementation: be respectively equipped with draw-in groove along screw propeller fin extension direction on the wall of the upper and lower chamber of cavity, the fine bar of carbon and draw-in groove are corresponding and be installed in the draw-in groove one by one.
The utility model has following advantage and effect with respect to prior art: in the utility model, the screw propeller fin is the fine fin of the carbon of inner hollow, be provided with the fine bar of the carbon of strengthening screw propeller fin intensity in the cavity of screw propeller fin, screw propeller has lightweight, high-intensity effect like this, satisfies the requirement of unmanned vehicle high standard.
