Problems solved by technology

Due to the limitation of battery capacity, battery-driven rotor-type unmanned aerial vehicles generally have short battery life, which limits the application of this type of aircraft
Using an oil-powered engine or increasing the size of the rotor will bring greater vibration to the body structure. The current structural form of the multi-rotor aircraft supported by a single rod can no longer meet the actual application requirements, and a multi-rotor with a more efficient structural layout is needed. aircraft

Embodiment Construction

[0028] The present invention will be described below in conjunction with the accompanying drawings, and the described preferred embodiments are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0029] Such as Figure 1-Figure 3 As shown, the present invention consists of a landing gear 1, a middle frame 2, a plurality of outriggers 3 connected to the middle frame 2, and a power terminal 4 positioned on each outrigger 3. The number of outriggers 3 depends on the number of power terminals 4, and can be even numbers such as 4, 6, and 8.

[0030] Such as Figure 4 As shown, the outrigger 3 is designed according to the equal strength criterion, the cross section is triangular, and starts from the connection between the side 36 and the middle frame 2, and the cross section decreases continuously to the end face 31, the side 36 is used to connect the middle frame 2, and the end face 31 is used for Connect power termina...

Abstract

The invention relates to a multi-rotor aircraft. The multi-rotor aircraft comprises a landing gear, a middle framework, a plurality of extending frames and power end heads, wherein the extending frames are connected with the middle framework; each power end head is positioned on each extending frame. The multi-rotor aircraft has the advantages that the structure adopts the modularizing design and manufacturing technology, so that the splitting package and transportation and site quick assembly functions are realized; the extending frames are designed according to an equal-strength principle, so that the weight of an aircraft body is reduced under the condition of ensuring strength and rigidity to meet property requirements, and the potential of oil-powered engines and large-size rotors in increasing cruising ability and load ability is fully realized.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a multi-rotor aircraft. Background technique [0002] Due to its good maneuverability and maneuverability, rotorcrafts are widely used in various fields. Due to the limitation of battery capacity, battery-driven rotor-type unmanned aerial vehicles generally have a short battery life, which limits the application of this type of aircraft. Using an oil-powered engine or increasing the size of the rotor will bring greater vibration to the body structure. The current structural form of the multi-rotor aircraft supported by a single rod can no longer meet the actual application requirements, and a multi-rotor with a more efficient structural layout is needed. aircraft. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, reduce the adverse effects caused by structural changes, and improve the endurance performance of the rotor...
