In order to study the stable flight of an electric aircraft in the whole flight speed range, taking the manned electric aircraft as an example, the method and principle of Longitudinal Trim for high aspect ratio aircraft are presented. Based on the wind tunnel test data, the torque produced by different gravity centers and tension lines as input parameters, and ignoring the influence of lateral and heading parameters, the three-degree-of-freedom motion equation of the aircraft is established, the difference of the performance parameters before and after the trim state is analyzed, which reflects the flight characteristics of the aircraft in a comprehensive way, and is compared with the flight test data. The simulative simulation data and the flight test data are in good agreement and have certain feasibility, it provides a reference for analyzing the performance parameter modification of other high aspect ratio electric aircraft in the future.
