More Information
Summary:The aircraft comprises a power system, an empennage and a main rotor above a fuselage, at least one anti-torque rotor is arranged around the fuselage, the anti-torque rotor and the main rotor are arranged in parallel, and the rotation directions of the anti-torque rotor and the main rotor are opposite; in the helicopter mode, the anti-torque rotor wings are used for balancing reaction torque and providing lift force for the aircraft at the same time; and in the autorotorcraft mode, the main rotor is disconnected from the power system and enters an autoroatation state, and the anti-torque rotor can tilt by 0-90 degrees around the transverse axis of the aircraft to provide advancing power for the aircraft. The unmanned aerial vehicle not only has the advantages of vertical take-off and landing, hovering, large load capacity and flexible direction of a helicopter, but also has the advantages of long voyage, high load ratio capacity, high safety and high stability of a gyroplane during voyage, and is simple in st
