Identification of Unsteady Aerodynamic Model Based on Wind Tunnel Test
摘要
Abstract
The linear superposition model, dynamic derivative model, mixed model and unsteady aerodynamic model are established based on the wind tunnel test results of the large-amplitude motion. The applicability of four kinds of aerodynamic models is analyzed. The former three models are suitable for the test results at the small angle of attack, but not at the large angle. Compared with the former two models, the mixed model is still applicable to the medium angle of attack. As for the unsteady aerodynamic model, the aerodynamic characteristics of coupled-motion are reflected well to the test results in spite of any angle of attack.关键词
