Problems solved by technology

[0002] In recent years, electric multi-rotor aircraft has gradually emerged in our country. Because the aircraft is disturbed by airflow or other aspects during flight, it is easy to cause the aircraft to have a slight resonance phenomenon during flight. This resonance phenomenon will reduce the flight life of the aircraft and the flight control. For this reason, we have developed a frame that eliminates the resonance of multi-rotor aircraft, which eliminates the resonance phenomenon generated by the aircraft during flight, and increases the service life of the aircraft and flight control

Abstract

The invention relates to a rack capable of eliminating the resonance of a multi-rotor aircraft. The rack comprises a central plate, wherein two carbon fiber tubes which are horizontally placed and are vertical to each other are arranged on the central plate, and an undercarriage placed horizontally is arranged below the central plate; two adjacent sides of the two carbon fiber tubes are connected by a connecting rod; four brackets distributed in a circumference and in an arc shape are arranged between the central plate and the undercarriage; and reinforcing rods are arranged between two ends of each carbon fiber tube and the undercarriage. According to the rack, two adjacent sides of the two carbon fiber tubes are fixed by the connecting rod, so that the resonance phenomenon generated by a motor is eliminated, and thus the service lives of the aircraft and a flight control system are prolonged.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a frame for eliminating resonance of a multi-rotor aircraft. Background technique [0002] In recent years, electric multi-rotor aircraft has gradually emerged in our country. Because the aircraft is disturbed by airflow or other aspects during flight, it is easy to cause the aircraft to have a slight resonance phenomenon during flight. This resonance phenomenon will reduce the flight life of the aircraft and the flight control. For this reason, we have developed a frame that eliminates the resonance of the multi-rotor aircraft, which eliminates the resonance phenomenon generated by the aircraft during flight, and increases the service life of the aircraft and the flight control. Contents of the invention [0003] The object of the present invention is to provide a frame for eliminating the resonance of the multi-rotor aircraft in order to overcome the deficiencies of the prior art, eli...
