Abstract: The post-stall maneuverability is a standard performance requirement for advanced fighters, and fighters with such ability possess tactic advantages in the close-range air battle, such as the fast occupancy, rapid acquiring, and agile evading. The model flight test is an important approach for the aerodynamics research, and it may play a vital role in addressing technical challenges of aircrafts development. In this paper, the post-stall maneuver model flight test technique upon the powered autonomous control flight platform, developed by the China Aerodynamics Research and Development Center, is introduced. The complete post-stall maneuver model flight test for an advanced fighter is demonstrated. Studies are expounded regarding the high angle-of-attack unsteady aerodynamics modeling, wide-range measurement of airflow parameters, nonlinear control for high angle-of-attack flight, thrust-vectoring implementation, and unsteady aerodynamic parameter identification, and approaches to address the critic problems therein are presented. The post-stall maneuver for the scaled model of advanced fighter is achieved for the first time in China. The resulting research fruits may provide meaningful technique supports for the achievement of post-stall maneuverability on real advanced fighters.
