Embodiment 1

[0037] figure 1 The front view of the multi-rotor aircraft provided by the embodiment of the present invention; figure 2 A three-dimensional schematic diagram of a multi-rotor aircraft provided by an embodiment of the present invention; image 3 Another perspective view of the multi-rotor aircraft provided for the embodiment of the present invention; as Figure 1-3 As shown, the multi-rotor aircraft provided by the embodiment of the present invention includes a main rotor 11 and several auxiliary rotors 12, wherein the main rotor 11 is driven by a fuel engine (not shown in the figure), and the main rotor 11 is installed on the body 1 of the fuel engine. The lower or upper end of the center position. The secondary rotors 12 are arranged around the machine body 1 , and the secondary rotors 12 are respectively driven by electric motors 122 .

[0038] In the above scheme, the main rotor 11 is installed on the lower side of the center of the body 1 of the fuel engine, and the m...

Embodiment 2

[0044] Figure 4 A three-dimensional schematic diagram of a multi-rotor aircraft provided by another embodiment of the present invention; Figure 5 A three-dimensional schematic diagram of a multi-rotor aircraft provided for another embodiment of the present invention; as Figure 4 and Figure 5 As shown, the multi-rotor aircraft provided by another embodiment of the present invention includes a main rotor 11 and several auxiliary rotors 12, wherein the main rotor 11 is driven by a fuel engine (not shown in the figure), and the main rotor 11 is installed on the fuel engine. The lower end or upper end of the central position of the body 1. The secondary rotors 12 are arranged around the machine body 1 , and the secondary rotors 12 are respectively driven by electric motors 122 .

[0045] In this embodiment, the plane of the auxiliary rotor 12 has an included angle with the plane of the body 1 (see Figure 4 ). Specifically, the auxiliary rotor 12 in the opposite direction ...

Embodiment 3

[0050] This embodiment serves as a kind of alternative scheme of embodiment 2, see Image 6 with Figure 7 , according to needs, this multi-rotor aircraft also includes balance wing 13, and the number of balance wing 13 is 1 or 2, and it is also directly driven by electric motor, and in this embodiment, the plane where balance wing 13 is located is the same as the plane where main rotor 11 is located. The plane is vertical, so that the anti-torque moment of the main rotor 11 can be offset by the balance wing 13 to control the yaw attitude, and then the inclined installation angle of the auxiliary rotor 12 in the left and right directions can be canceled.

[0051] As a preferred embodiment, the multi-rotor aircraft includes 4 auxiliary rotors 12 and 1 balance wing 13, specifically, an extension arm 131 is extended on the arm of one of the auxiliary rotors 12, and at the end of the extension arm 131 Balance motor 132 is fixedly installed, and balance wing 13 is driven by balanc...

Abstract

The invention provides a multi-rotor type aircraft. The multi-rotor type aircraft comprises a main rotor and a plurality of secondary rotors, wherein the main rotor is driven by a fuel engine, and is arranged at the lower end or the upper end of the center position of the engine body of the fuel engine; the plurality of secondary rotors are distributed on the periphery of the engine body; the secondary rotors are driven by motors respectively. The multi-rotor aircraft has the advantages of high carrying capacity and long voyage time.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a multi-rotor aircraft. Background technique [0002] Aircraft (flight vehicle) is a flying object manufactured by humans, capable of flying off the ground, flying in space and controlled by humans. Among the existing flying objects, multi-rotor aircraft with vertical take-off and landing and hovering capabilities have a very wide range of applications. Compared with traditional single-rotor helicopters, they have simple structure, easy maintenance, small blade damage, Features for operational safety. Not only is it playing an increasingly important role in the military field, but it is also widely used in many civilian fields such as aerial photography, agricultural plant protection, power line inspection, traffic inspection and disaster assessment. [0003] At present, multi-rotor aircraft are driven by battery-powered electric motors. Since the bottleneck of battery technology has no...
