Foldable Y shaped three axis two-layer six rotorcraft

The invention relates to a foldable Y-shaped aircraft with three shafts and two-layered six rotor wings, which overcomes the defects of existing aircrafts with multiple rotor wings that opposite torque forces that are generated by corresponding positive and negative rotor wing groups counteract with each other through a supporting arm, as the supporting arm has a certain length and large structural weight loss, the torque moment counteracting effect is limited, and as the single-layered rotor wings are positioned on a same horizontal plane, the aircraft has limited motion power. The structure of the foldable Y-shaped aircraft with three shafts and two-layered six rotor wings consists of a main body, three groups of electric motor installation hood, three groups of supporting arms that connect the electric motor installation hood and the main body, three groups of rotor wings and a plurality of fasteners; each group of rotor wings has two rotor wings that are respectively arranged at an upper top end and a lower top end of the electric motor installation hood and are the positive and negative rotor wings which have the same geometrical shape and the opposite rotary direction. As the upper and lower two rotor wings of each rotor wing group are the positive and negative rotor wings that have the same geometrical shape and the opposite rotary direction, the torque forces generated by the rotation of the upper and lower rotor wings can counteract with each other, thus realizing the self-equilibrium during the movement of the aircraft, and the foldable Y-shaped aircraft has simple structure and better flexibility and stationarity, can be folded and is convenient for carry and transportation.
