The steering engine controls the inclination angle of the blade through the pitch transmission structure, changes the pitch of the blade, and enables the unmanned aerial vehicle to make corresponding actions.

Most unmanned aerial vehicles in the market adopt single rotor or multi-rotor structures, and the difference between the unmanned aerial vehicles is that the double rotor unmanned aerial vehicle is combined in two modes of directional control: the rotating speed of one rotor head and the inclination of the blades are controlled, and when the two rotor heads are turned in the direction pointed by the two rotor heads, the rotating speed of one rotor head is reduced, and the rotating speed of the other rotor head is increased, so that the rotating speed of the other rotor head is finished; when the direction perpendicular to the pointing directions of the two rotor heads is controlled, the steering engine drives the middle domain body to incline, the cross disc is driven to incline by the incline of the middle domain body, and the slurry clamp is inclined according to the required direction by the cross disc through the phase rocker arm and the slurry push rod.

When the double-rotor unmanned aerial vehicle flies, the rotating speed of the rotor head is very fast, the flying direction of the double-rotor unmanned aerial vehicle is wanted to be changed through the steering engine, the acting force on the steering gear is very large, the existing rotor head is directly connected with the steering engine through the steering shaft, and the connecting part is required to bear all interaction forces in such a connecting mode, so that the steering shaft is worn.

Therefore, we propose a rotor head structure of a dual rotor unmanned aerial vehicle.
