Propeller having adjustable effective aerodynamic force

Abstract

The invention relates to the airplane transmission mechanism technology field, especially relates to a propeller having adjustable effective aerodynamic force. The propeller comprises a transmission shaft, a transmission base, and propeller blades. The center position of the inner part of the transmission base is provided with a circular assembly blind hole. The propeller having the adjustable effective aerodynamic force is characterized in that the transmission shaft, the transmission base, and the propeller blades are assembled and arranged in a split manner, and then each component is fixedly disposed by a bolt, and then the components having different specifications can be dismounted and replaced according to requirements, and therefore the dynamic property, the durability, the material and the noise can be adjusted, and expandability is strong, the later maintenance is convenient, and at the same time, the propeller can be screwed on an external screw assembly rod by using an assembly nut, can be disposed on an external positioning rod in a sleeved manner by an external positioning slot, and can be inserted in an arc-shaped limiting slot by using an arc-shaped assembly strip to improve the assembly firm performance of the abovementioned components.

Description

technical field [0001] The invention relates to the technical field of aircraft transmission mechanisms, in particular to an adjustable high-efficiency aerodynamic propeller. Background technique [0002] Propeller refers to a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There may be two or more blades connected to the hub, and the rear side of the blades is a helical surface or similar to a helical surface. A propeller. There are many types of propellers, and they are widely used, such as propellers for airplanes and ships. At present, most of the propellers used for aircraft on the market are fixed in structure. Once the structure and specifications are produced, they cannot be adjusted and replaced. As a result, their power, durability, material and noise control cannot be adjusted and replaced in the later stage, and the expansion and playability are very limited. Later maintenance is also more trou...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problems in the above-mentioned background technology, an improved adjustable high-efficiency aerodynamic propeller is provided, which solves the problem that most of the propellers used for aircraft on the market are fixed in structure, and once the structure and specifications are produced It cannot be adjusted and replaced after it comes out, so its power, durability, material and noise control cannot be adjusted and replaced in the later stage. The expansion and playability are very limited, and the later maintenance is also more troublesome.
