It is important to determine pitching dynamic aerodynamic performance and test data precision of models with high angle of attack in high speed wind tunnel to meet the needs of evaluating aerodynamic performance, designing control system with precision and achieving maneuverability fight of aircraft. The dynamic performance and repeated test data precision of 70° delta wing model, SDM and Su-27 fighter model with high angle of attack in the dynamic experimental system with large amplitude of FL-24 wind tunnel have been obtained, which can be used as a standard for investigations on dynamic test of models. The obtained results under the test conditions basically meet the standards of those with steady force test of models with high angle of attack in high speed wind tunnel.
