T-tail flutter wind tunnel test model design and validation
Due to the relationship between the flutter characteristics of T-tail aircraft and the static lift of the horizontal tail, the accuracy of theoretical predictions for the flutter speed of T-tail aircraft decreases. Therefore, it is particularly important to design precise T-tail flutter wind tunnel test models for wind tunnel testing. This paper systematically studies the design and validation methods for the stiffness, mass, and inertia of T-tail flutter wind tunnel test models. Through T-tail flutter wind tunnel tests, the effects of variations in the static lift of the horizontal tail and the bending and torsional stiffness of the vertical tail-fuselage connection joints on the T-tail flutter speed were validated. The research shows that the errors between the tested values (such as the center of mass, inertia, and natural frequencies) of the designed T-tail flutter wind tunnel test models and the theoretically calculated values are within 4%, and the predicted critical flutter speed error is within 5%. Increasing the torsional stiffness of the vertical tail-fuselage connection significantly improves the critical flutter speed, while increasing the bending stiffness of the vertical tail-fuselage connection reduces the critical flutter speed. The flutter test results provide important guidance for the overall layout of the horizontal tail and the structural stiffness design of the vertical tail in T-tail configurations.
