The invention provides a duct powder device and an aircraft. The duct powder device comprises a first duct, wherein a first rotor device is arranged in the first duct; the first rotor device and the first duct are coaxially arranged; the first rotor device is driven by the first power device and rotates around the axis of the first duct; a second duct is arranged outside the first duct; the second duct and the first duct are coaxially arranged; a second rotor device driven by a second driving device is arranged in the second duct, and is positioned between the first duct and the second duct; the second rotor device and the second duct are coaxially arranged. The aircraft comprises a frame and a duct power device mounted on the frame. The duct power device can reduce the mutual disturbance of fluid, thereby reducing the energy loss of the duct powder device.
