The invention relates to the field of sensor design, in particular to a rotor wing unmanned aerial vehicle lift force feedback system based on air pressure type force sensing, an air pressure type force sensor is used for collecting lift force generated by a rotor wing to obtain a lift force measured value; the filter is used for filtering the lift force measured value and taking the filtered lift force as a feedback signal of the single-shaft lift force feedback system; and the force feedback controller is used for taking the lift force deviation obtained by the difference between the feedback signal and the expected lift force as an input signal of the force feedback controller, and outputting an adjusting quantity to the power system of the unmanned aerial vehicle through the force feedback controller, so that the power system adjusts the rotating speed of the motor through the electronic speed regulator, and then the rotor wings are driven to rotate to generate lift force. The air pressure type force sensor has the advantages of being low in manufacturing cost and light in weight, the cruising ability of the rotor wing unmanned aerial vehicle can be improved, and the load pressure is relieved; the flexible structural design and installation mode can reduce the influence of dynamic torque, and the control accuracy and robustness of the lift feedback system are improved.
