Abstract
In recent years, fiber-reinforced composites have been increasingly used in the aeronautical field to improve the structural efficiency and reduce the weight of the aircraft. Furthermore, in order to enhance the aerodynamic performance, aircraft with highly elongated wings have been also extensively investigated. Within this context, this work presents a beam finite element model for aeroelastic analysis of elongated plate-like wings made of composite material. For validation purposes, a concentrated mass has been added to the model and modeled as a ballast located at the wing tip. A parametric study in terms of aeroelastic stability (flutter speed) has been carried out varying the positions of the ballast along the chordwise direction for different layup configurations.
