The invention belongs to the technical field of unmanned aerial vehicle design, and discloses a dual-redundancy electromechanical actuation front wheel turning device for an unmanned aerial vehicle, which comprises a driving mechanism, a planetary reducer, an output gear, a feedback sensor and an electromagnetic damper, the driving mechanism is connected with the input end of the planetary reducer, the output end of the planetary reducer is connected with the output gear, and the feedback sensor is connected with the output gear through parallel shaft transmission. Wherein the planetary reducer comprises a differential epicyclic gear train, a WW type planetary reducer and an NW type planetary reducer from top to bottom, and the electromagnetic damper is connected with the output end of the WW type planetary reducer. An electric actuation mode is adopted, the direction control function in the ground sliding and landing process of the unmanned aerial vehicle can be achieved through an onboard power source, the integrated electromagnetic damper is designed, shimmy damping of the front wheels is achieved, the requirements of multi-electric and full-electric aircrafts are met, and due to the fact that the dual-redundancy motor and the dual-redundancy feedback sensor are adopted, the unmanned aerial vehicle is more stable in performance. Therefore, the device has the characteristic of high reliability.
