Description

[Technical field]

[0001] The present invention relates to a ducted aircraft, in particular to a single-ducted aircraft. [Background technique]

[0002] Ducted fan aircraft has the advantages of compact structure, good maneuverability, strong environmental adaptability, etc., and the scope of use has been extended to the three major fields of military, civil and scientific research. focus on. The structure of the ducted UAV includes: annular wing (ducted), paddle disc, tail rudder and fuselage. Among them, the annular wing and fan play an important role in the forward flight of the ducted fan UAV, and the driving force of the whole aircraft is provided by this. When the annular wing UAV takes off on the vertical plane, the reaction force of the propeller on the air and the additional thrust of the annular wing act together; the yaw, pitch and roll of the ducted fan aircraft during forward flight are determined by Control the role of the rudder surface to achieve.
