[Abstract]:In order to meet the requirements of domestic fighter models for the study of unsteady aerodynamic problems in the process of high angle of attack stall maneuver, A set of two-degree-of-freedom large-amplitude oscillation test technology based on coupling drive of electro-hydraulic servo motor and motor has been developed in FL-8 wind tunnel by China Aeronautical Industry aerodynamics Research Institute. The basic composition and test principle of the system are briefly introduced. The typical results of the two-degree-of-freedom large-amplitude oscillation test of the dynamic standard model of FL-8 wind tunnel are given. The analysis shows that the operation performance of the system is stable and the test data are reliable. Because of its high repeatability, it can be used to study the aerodynamic characteristics of two-degree-of-freedom coupling motion of aircraft.
