Propeller yaw device and unmanned aerial vehicle thereof

Abstract

The invention provides a propeller yaw device and an unmanned aerial vehicle thereof. The propeller yaw device comprises a linking bearing, a transmission robot arm group and a yam control unit, the transmission robot arm group is arranged on the upper connecting part of the linkage bearing, and is connected with blade linking arms, the yam control unit is arranged at the lower end of the linkingbearing, the control unit is composed of a pedestal, a deflection tray and a transmission assembly, the transmission assembly controls the linking bearing to move up and down in order to realize the control of the transmission robot arm at the upper end of the linking bearing and realize the control of every blade linking arm, and the control precision is realized through a steering engine connected with the transmission assembly in order to realize the simple and stable motion control of an aircraft, so the problem of low yam control precision caused by difficult yam control due to too complex mechanical structure of existing unmanned aerial vehicle yam control devices is solved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a propeller yaw device and an unmanned aerial vehicle thereof. Background technique [0002] With the gradual development of aviation technology, especially for UAV yaw control technology is very important, when a UAV needs to change the flight direction during flight, it needs to achieve very precise and fast control, The UAV needs to be equipped with a very complete yaw control system. In the current yaw control technology, most of them use dual propellers to control the rise and fall of the UAV by controlling the rotation rate of the upper and lower propellers. , control the left and right swing of a single propeller to control the left and right yaw, but this control method will lead to a very complicated propeller structure of the UAV, requiring multiple controllers to control each propeller separately, and the mechanical structure of the propeller requires ...
