The invention provides a ducted power device and an aircraft. The ducted power device comprises guide plates which are configured to allow the direction of the component velocity of air flow, guided by the guide plates to move along the duct direction, to be opposite to the rotary direction of rotors, so that relative velocity between the air flow and the rotors is increased, and not only can disturbed flow in the inlet of a duct be relieved, but also pneumatic efficiency of the ducted power device can be improved.
