The invention discloses a ducted fan and propeller combined vertical fixed wing aircraft propelling structure which comprises an engine, a ducted supporting rod is fixedly connected to the engine, a ducted wall is fixedly connected to the ducted supporting rod, a ducted fan is arranged in the ducted wall and comprises ducted blades, the propeller is arranged in front of airflow of the ducted wall, and the ducted blade is arranged in front of airflow of the ducted wall. An output shaft of the engine is coaxially and fixedly connected with a rotating shaft; the rotating shaft is coaxially and fixedly connected with a ducted fan and a propeller; the section of the duct wall adopts a wing-shaped appearance design; the diameter of the propeller is larger than that of the duct wall. Large thrust can be generated in a small-size space, and meanwhile the hovering efficiency is higher.
