摘要：NOVELTY - This utility new type provide a one coaxial double rotary wing type small micro-aircraft, this aircraft comprising a machine body, a dual-system and the bypass system, a wing comprising symmetrically set on the machine body of a lower two side of upper rotor and a lower rotor system, a rotor and a lower rotor system rotation mechanism through a upper, lower main transmission shaft reverse drive rotation mechanism is differential located inside and has a bevel gear and a transmission ratio of the differential and upper, lower main transmission shaft coaxial to a rotation, the bypass system set on the machine body and the tail part through one tilting regulating component and the machine body is connected with a bypass line and a differential mechanism vertical to the axis of upper and lower main transmission shaft. This utility new type a the helicopter and a rotorcraft, the aircraft is capable of improving air field distribute, has a simple structure, safe and reliable, flexible, economical and practical, and has strong commonality and so on.
