Problems solved by technology

[0004] At present, some domestic multi-rotor UAVs have a large load, but they are large in size, and the wheelbase is usually above 800mm, so the scope of use is greatly limited; some small quad-rotor UAVs are small in size, but The load is also very small, only 500-1000 grams

Embodiment Construction

[0019] The present invention is described in further detail now in conjunction with accompanying drawing. The following drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner.

[0020] Such as figure 1 with figure 2 As shown, the present invention provides a double-deck eight-rotor aircraft, comprising a body 1, eight motor booms 2, eight motor mounts 3, eight motors 4, four upper rotors 5, four lower rotors 6 and Four supporting feet 7, the angle between eight motor booms 2 and adjacent motor booms 2 is 45° and one end is fixed to the body 1, and the other end is fixedly connected to a motor mount 3 respectively, and the eight motor mounts 3 are respectively installed with a motor 4, wherein the motors 4 located in the four positions of front, rear, left and right are upward, the motors 4 located in the four positions of left front, right front, left rear and right rear are downward, and the fo...

Abstract

The invention discloses a double-layer and eight-rotor-wing aircraft, and relates to the technical field of unmanned aerial vehicles. The double-layer and eight-rotor-wing aircraft comprises an aircraft body, and eight rotor wing components mounted on the aircraft body; angles between the adjacent components are 45 degrees; each rotor wing component includes a motor suspension arm, a brushless motor and a rotor wing; the rotor wings are connected with output ends of the brushless motors; the brushless motors are mounted at the tail ends of the motor suspension arms; mounting holes are formed in the aircraft body; the other tail ends of the motor suspension arms penetrate through the mounting holes, and are clamped on the aircraft body through mechanisms on two sides of the mounting holes; the mounting directions of the rotor wing components are opposite to the mounting directions of the adjacent rotor wing components; if the motor of one rotor wing component is upward, the motors of the adjacent components are downward, and vice versa; and the rotor wings of the adjacent rotor wing components are slightly overlapped, and are opposite in rotating directions. As eight rotor wings are mounted on the unmanned aerial vehicle, the lift of the aircraft is increased; and through double-layer arrangement of the rotor wings, the size of the aircraft is smaller, and the size of the aircraft is reduced.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a double-deck octarotor aircraft. Background technique [0002] Rotorcraft with a plurality of rotor blades are sufficiently known in the prior art. The most popular is the quadrotor aircraft, which is defined by four rotors arranged in the same plane and acting vertically downwards. The advantage of a rotorcraft with multiple rotor blades is generally that the three flight axes: longitudinal, transverse and vertical can be controlled individually by varying the rotational speed of the individual rotors. [0003] The octarotor aircraft is derived from the traditional quadrotor aircraft, including two structural forms, one is to install eight rotors on the same plane, the other is to install four coaxial rotors on the same plane, and the quadrotor aircraft In comparison, the eight-rotor aircraft uses eight rotors to generate lift, which is greater than the lift ...
