| Abstract: | An improved high speed wind tunnel wall signature method is used for a practical high blockage aircraft model test under the conditions of \%Ma\%≤0.9 and high angle of attack to calculate the wind tunnel interference effects on model aerodynamic forces and pitching moment.It takes the interference velocity undulation into account for the aerodynamic forces and pitching moment corrections to solve the difficult moment correction problem in high angle of attack tests.The tunnel interference effects are assessed and corrected using the measured tunnel wall pressure data,so the method can be applied to various ventilated or solid wall wind tunnels. |
