An Intelligent Algorithm for Aerodynamic Parameters Calibration of Wind Tunnel Experiment at a High Angle of Attack

In this paper, an intelligent algorithm for the aerodynamic parameter calibration of wind tunnel experiments advanced layout aircraft at a high angle attack is proposed. The proposed based on homologous comparison and tuning algorithm, it can effectively improve accuracy experiment model. First, analysis large oscillation experimental data scaled aircraft, model composed static derivative, dynamic rotating balance derivative established. Second, to effectively, idea combing layered correction method solves problems complex structure, amount data, poor in models aircraft. Finally, interface software designed MATLAB GUI, which integrates methods ideas realizes effective adjustment parameters simulation flight test This study provides reliable engineering technical means subsequent verification
