The invention belongs to the technical field of aircrafts, and discloses a ducted fan and an aircraft.The ducted fan comprises an annular duct and a fan arranged in the annular duct, and the fan comprises a fan inner ring suitable for being used as a rotor, a fan outer ring suitable for being used as a rotor and a plurality of fan blades connected between the fan inner ring and the fan outer ring; the inner wall and the outer wall of the annular duct are respectively provided with a stator, and the annular duct is matched with a fan inner ring and a fan outer ring of the fan through the two stators so as to drive the fan to rotate in the annular duct. A sliding installation assembly is arranged in the annular duct and provided with an inner ring sliding rail and an outer ring sliding rail. According to the invention, the annular propeller hub and the motor rotor are combined into a whole, the fan can do annular track motion in the track under the running fit of the inner ring sliding track and the outer ring sliding track, the centrifugal force generated by high-speed rotation acts on the middle of the fan blades, the structure is more stable, the strength is higher, the weight is lighter, and the rotating speed is higher.

    本发明属于飞行器技术领域,公开了一种涵道风扇及飞行器,其中涵道风扇包括环形涵道和设于环形涵道内的风扇,所述风扇包括适于作为转子的扇内圈、适于作为转子的扇外圈以及连接在扇内圈与扇外圈之间的若干扇叶;所述环形涵道的内壁和外壁分别设有一定子,并通过两个定子分别与风扇的扇内圈和扇外圈配合,以驱使风扇在环形涵道内转动;在所述环形涵道内设有滑动安装组件,滑动安装组件具有内圈滑动轨道和外圈滑动轨道。本发明将环形浆毂与电机转子合二为一,并通过内圈滑动轨道和外圈滑动轨道的转动配合下,可使得风扇在轨道内作环形轨道运动,高速旋转产生的离心力作用于扇叶中间,结构更稳定,强度更大,重量更轻,转速更高。
