Problems solved by technology

[0002] As a new type of aircraft, the multi-rotor unmanned helicopter has the advantages of stable flight, electric drive, small vibration, and flexible maneuvering. It is necessary to prepare more batteries to prolong the battery life, but the weight of the battery itself greatly limits the load capacity of this aircraft and limits the application field of multi-rotor aircraft as an air platform.

Embodiment Construction

[0016] control figure 2 , taking the quadrotor as an example to illustrate the implementation process of the present invention.

[0017] Large-load quadrotor unmanned helicopter, including: fuselage, 4 symmetrically distributed rotors, all of which are driven by electric motors; 4 electric motors 4 paired with the rotors, ground power supply 8, and a ground brushless variable frequency motor controller 7. Cable 5, cable reel 6; the power of the motor is transmitted from the ground through the cable, which reduces the weight of the battery attached to the quadrotor fuselage and improves the payload; moment adjustment.

Abstract

The invention relates to a rotor wing type unmanned plane and further relates to a multi-rotor-wing unmanned helicopter. The invention aims to provide the multi-rotor-wing unmanned helicopter which is not influenced by a battery and has strong load capability. The heavy-load multi-rotor-wing unmanned helicopter comprises a fuselage and four or more than four rotor wings, and is characterized in that the rotor wings are driven by a motor; and a power supply of the motor is transmitted from a ground through a cable. Compared with the prior art, the heavy-load multi-rotor-wing unmanned helicopter has the advantages of being used as a lifted-up platform, wherein the weight of the battery on a multi-rotor-wing machine is reduced, and more instruments and equipment can be placed on a plurality of the rotor wings.

Description

technical field [0001] The present invention relates to a rotary-wing unmanned aerial vehicle, and further relates to a multi-rotor unmanned helicopter. Background technique [0002] As a new type of aircraft, the multi-rotor unmanned helicopter has the advantages of stable flight, electric drive, small vibration, and flexible maneuvering. It is necessary to prepare more batteries to prolong the battery life, but the weight of the battery itself greatly limits the load capacity of this aircraft, and limits the application field of multi-rotor aircraft as an air platform. Contents of the invention [0003] The purpose of the present invention is to provide a multi-rotor unmanned helicopter that is not affected by batteries and has a strong load capacity. [0004] Technical scheme of the present invention is as follows: [0005] The large-load multi-rotor unmanned helicopter includes: a fuselage, four or more rotors 3 in groups, and the rotors are all driven by a motor 4, ...
