Ducted coaxial multi-rotor type aircraft
The invention discloses a ducted coaxial multi-rotor type aircraft and belongs to the field of special aircrafts. The multi-rotor type aircraft comprises an airframe structure, a power system and a control system. The airframe structure comprises a central duct, a main rotor and a plurality of assistant rotors evenly distributed at the peripheral of the central duct. The main rotor comprises an upper propeller and a lower propeller. The upper and lower propellers are fixed in the central duct. The centers of the upper and lower propellers are at the same vertical axis and the directions of the upper and lower propellers are opposite. A rotation device is connected to the outside of a supporting structure. The assistant rotors are connected to the rotation device through retractable rocker arms. The rotation device controls the rocker arms to drive the assistant rotors to rotate around connection points of the assistant rotors and the supporting structure. The assistant rotors can rotate and move freely, and therefore the aircraft can change the lift force distribution of the aircraft according to flight needs and a good maneuvering characteristic of the aircraft is achieved. The assistant rotors can be retracted into the inside of the central duct so as to reduce the size of the aircraft, thus facilitating flight in narrow spaces.
