Multi-rotor aircraft capable of hovering in any attitude

The invention discloses a multi-rotor aircraft capable of hovering in any attitude, and belongs to the field of aircraft structure design, the whole aircraft is composed of carbon fiber tubes and printing pieces, adjacent carbon tubes are connected and reinforced through 3D printing pieces, observation is carried out with the upper vertex as a reference point, the center part is a regular tetrahedron, and the three-dimensional printing pieces are arranged on the carbon fiber tubes. The three-side structure units extend in the normal direction of the tetrahedron frame, the six extending three-side structure units are combined with the tetrahedron frame, the whole unmanned aerial vehicle is in central symmetry, and the problem that a common multi-rotor unmanned aerial vehicle cannot hover at any angle can be solved.
