Problems solved by technology

Because usually only one set of rotors is arranged in the duct of the existing aircraft, the rotation of the rotors generates a large torque, which is not conducive to the control of the aircraft.
If two groups of rotors overlapping each other on the axis of the duct are arranged in the duct, it will cause the problem of low aerodynamic efficiency

Abstract

The present invention provides a ducted power device and an aircraft. The ducted power device includes a first duct, a first rotor device is arranged in the first duct, the first rotor device is coaxially arranged with the first duct, and the second A rotor device is driven by the first power device and rotates around the axis of the first duct, wherein a second duct is arranged outside the first duct, the second duct is coaxially arranged with the first duct, and the second duct There is a second rotor device driven by the second power device inside, the second rotor device is located between the first duct and the second duct, and the second rotor device and the second duct are coaxially arranged. The aircraft includes a frame and a ducted power device installed on the frame. The ducted power device of the invention can reduce the mutual disturbance of fluids, thereby reducing the energy loss of the ducted power device.

Description

technical field [0001] The invention relates to the field of power supply equipment, in particular to a ducted power device and an aircraft using the ducted power device. Background technique [0002] Unmanned aerial vehicles are widely used in aerial photography, air transportation and other fields. Most of the existing unmanned aerial vehicles are fixed-wing aircraft or multi-axis aircraft. One or more wings are set on the fixed-wing aircraft, and the wings The propeller is arranged on the top, and the airflow generated by the rotation of the propeller driven by the motor propels the aircraft to fly. [0003] A multicopter is a rotorcraft with two or more rotor axes, such as figure 1 As shown, an existing multi-rotor aircraft has four rotor shafts, and the aircraft has a frame 10 on which a power supply, a control circuit, etc. are arranged, and the frame 10 is provided with four supporting shafts 12, The four support shafts 12 are evenly arranged in the circumferential ...
