Abstract

The invention relates to a multi-rotor aircraft body made of a composite material. The multi-rotor aircraft body is composed of an equipment compartment, cantilevers, undercarriages, rotors, an anti-collision ring and hangers. The equipment compartment is located inside, the anti-collision ring is located outside, the equipment compartment and the anti-collision ring are connected through the cantilevers, and the cantilevers are provided with motor installation platforms used for installing motors and the rotors. The undercarriages are connected with the lower portion of the equipment compartment, and the hangers are arranged on a middle truss structure and can be used for installing onboard equipment or used for medical rescue. Compared with a metal aircraft body, the multi-rotor aircraft body made of the composite material is simple in structure, under the condition that the use condition is met, the aircraft body made of the composite material has the obvious weight reducing beneficial effect, and energy consumption can be reduced due to the reduction of the weight.

Description

technical field [0001] The invention relates to the technical field of aircraft body, in particular, it relates to a composite material multi-rotor aircraft body and a preparation method thereof. Background technique [0002] At present, there are various forms of multi-rotor aircraft, but the application range of conventional commercial-grade multi-rotor aircraft is limited due to the limitation of flight time and flight load. Most of them are used for flight performances, flight photography and other purposes. Moreover, during the flight, the space environment is relatively complex, and the blades are easily damaged by the impact of solid garbage, birds and other unknown objects. Once the blades are damaged, it will directly affect the flight effect of the entire multi-rotor aircraft, which is not conducive to its work. normal operation. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide ...
