Air vehicle

Abstract

The invention discloses an air vehicle. The air vehicle comprises an upper propeller (1), a lower propeller (2) and an air vehicle body (3), wherein a first motor (4) and a second motor (5) are arranged inside the air vehicle body (3), the first motor (4) is connected to the lower propeller (2) through a first transmission shaft (42), the second motor (5) is located below the first motor (4) and connected to the upper propeller (1) through a second transmission shaft (52), and the second transmission shaft (52) penetrates through the first motor (4), the first transmission shaft (42) and the lower propeller (2) in sequence and then is connected to the upper propeller (1); the second transmission shaft (52) and the first transmission shaft (42) share the same axial center, and the upper propeller (1) and the lower propeller (2) rotate at the same speed in different directions under the driving of the motors respectively. The air vehicle has the advantages of being simple in structure, high in bearing capacity and low in wind resistance.

Description

technical field [0001] The invention relates to the technical field of aircraft design, in particular to an aircraft with two coaxial propellers and two motors. Background technique [0002] At present, coaxial dual-propeller aircraft can be divided into two types: single-motor drive and dual-motor drive. The motor of a single-motor aircraft needs to drive two propellers. Drive direction so that the two propellers spin in opposite directions at the same speed. Disadvantages of single-motor aircraft are: low load, not suitable for carrying additional camera modules. Generally, a lightweight camera module is built into the aircraft. Since the camera module is directly bound to the aircraft, it is not easy to replace the camera module. [0003] The dual-motor aircraft has a stronger carrying capacity than the single-motor aircraft. The motor layout of the dual-motor aircraft includes vertical layout and horizontal layout. The horizontal layout of the dual-motor aircraft needs ...

Problems solved by technology

The disadvantages of single-motor aircraft are: the load is low, and it is not suitable to carry an additional camera module. Generally, a lightweight camera module is built into the aircraft. Since the camera module is directly bound to the aircraft, it is not easy to replace the camera module.

[0003] The dual-motor aircraft has a stronger carrying capacity than the single-motor aircraft. The motor layout of the dual-motor aircraft includes vertical layout and horizontal layout. The horizontal layout of the dual-motor aircraft needs to use transmission components such as gears or belts to drive the upper and lower propellers. The horizontal layout The disadvantage of the current dual-motor aircraft is that transmission components such as gears and belts need to be used to drive the propeller, and there is a problem of wear and aging of the transmission components.

[0004] The dual-motor aircraft with vertical layout needs to set up a wiring support frame outside the propeller, and the wiring between the motor and the propeller can be realized with the help of the wiring support frame. wire support frame, resulting in an increase in the weight of the aircraft
