The invention discloses a micro-miniature foldable wheel-shaped aircraft and belongs to the technical field of aviation systems. The related wheel-shaped aircraft is mainly composed of components including an aircraft body, a rotor wing supporting frame, a vector power set, a folding locking mechanism and the like. The wheel-shaped aircraft mainly includes two state modes which are a folded mode and a flying mode respectively and can achieve the functions of ground rolling advancing, flying in air and the like, wherein in the folded mode, the aircraft is folded into a wheel shape and is used for rolling advancing or user carrying, and meanwhile multiple aircrafts can be combined in the wheel-shaped mode to carry out cooperative combat tasks conveniently; in the flying mode, the aircraft isunfolded into the vector two-rotor-wing mode under driving of the folding locking mechanism and is used for executing flying tasks. The aircraft has the advantages of being novel in structure, convenient to carry, foldable, various in function and capable of facilitating individual combat use.
