The invention belongs to the field of aerodynamic layout design of aircraft control surfaces, and relates to a control surface upper rotating shaft design method giving consideration to a lift augmentation target and drag reduction ability, which comprises the following steps of: performing integrated fusion design on an actuator cylinder bump and a wing lower surface, obtaining a current position of a control surface rotating shaft and a distance L1 from the control surface rotating shaft to the wing lower surface, and determining an adjustable range of the control surface rotating shaft; and performing iterative simulation calculation, and setting proper criteria to obtain a group of simulation data with optimal comprehensive evaluation as the final position of the control surface rotating shaft and the final contour of the actuator cylinder bump. Through the optimal design of the upper and lower positions of the rotating shaft, the supersonic resistance is reduced by 50% compared with the traditional lower rotating shaft design, the aerodynamic layout design contradiction under multiple design constraints is relieved to a certain extent, the control surface rotating shaft design method can be popularized to other aircraft control surface rotating shaft design, and the aircraft performance is improved.
