Aeroelastic analysis of flexible large aspect ratio wing

Research output: Contribution to journalArticlepeer-review

Abstract

Aeroelastic phenomena are significant for high-altitude long-endurance aircraft with large aspect ratio wing. The effect of structural geometrical nonlinearity on wing dynamic characteristics and the changes of unsteady aerodynamics due to the large static deformation of wing were studied. The wing flutter was carried out based on the result of large deflected wing vibration analysis using quasi-linear method and its unsteady aerodynamics by strip theory. Through the calculation of the wing, it can be concluded that the flutter speed decreases under large deformation.
