Magnetic levitation ducted fan for electric aircraft

Abstract

The invention provides a magnetic levitation ducted fan for an electric aircraft, which comprises a shell, a stator, a first coil, a rotor fan and a permanent magnet, aiming at a high-rotating-speed low-noise electric propulsion mode adopted by an oil-electricity hybrid power aircraft, a magnetic levitation technology is adopted, a traditional shafting power system is decoupled in a shaftless manner, the traditional shafting structure limitation is eliminated, suspension rotation of the rotor fan is achieved through the mixed magnetic suspension bearing, and the low-noise environment-friendly requirement is met. The magnetic levitation ducted fan has higher efficiency, can generate greater thrust under the same power consumption, and realizes high speed, shaftless and environment-friendly effects of the electric propulsion device of the oil-electricity hybrid power aircraft.

Description

technical field [0001] The present disclosure relates to the technical field of aircraft electric propulsion devices, in particular to a magnetic levitation ducted fan for electric aircraft. Background technique [0002] At present, the existing aircraft propulsion device is mainly shafting structure transmission, and the traditional shafting structure power device mainly has the following defects: the traditional electric propulsion device is driven by the shafting system, and the rotational speed is affected by the structure; and the propulsion structure of the traditional shafting structure power device Connected with the shaft system, it will generate huge noise when rotating, causing sound pollution to the environment. The problems of traditional shafting structure power devices such as high noise, low efficiency, and small thrust can no longer meet the society's increasing demand for environmental protection and high efficiency. At the peak of research, if a breakthro...
