The invention provides an intelligent linear steering engine suitable for an unmanned helicopter. The intelligent linear steering engine comprises a lead screw pipe and a dual-redundancy servo motor. A thrust pipe is arranged in the lead screw pipe, and a lead screw is arranged in the thrust pipe; one end of the thrust pipe is connected with the knuckle bearing push rod through the knuckle bearing adjusting pipe, and the other end of the thrust pipe is connected with the lead screw; one end of the lead screw is connected with an angle sensor through a large straight gear, and the angle sensor is sleeved with an angle sensor cover plate. According to the invention, a dual-redundancy servo motor is adopted, the reliability of the motor is improved, and power-off self-locking and remote communication are completed through an integrated controller and an actuator in the servo motor; the straight gear is adopted for speed reduction and torque increase, the transmission efficiency is high, the reliability is good, the production cost is low, the split type lead screw shell is adopted, the shell machining difficulty is reduced, and the production cost is further reduced; a strain gauge and a rotary transformer are installed on a rear shell of the steering engine, and the load borne by the linear steering engine and the output stroke are detected and fed back to a control system in real time.
