Aeroelasticity is a branch of aerospace engineering that deals with the interaction between an aircraft's aerodynamic forces and its elastic structure. This field is crucial for designing aircraft that can withstand the dynamic loads and vibrations encountered during flight. Aeroelastic phenomena include flutter, divergence, and control reversal, which can significantly affect an aircraft's performance and safety if not properly addressed.

Flutter is a self-excited oscillatory motion that can occur when the aerodynamic forces on an aircraft's structure cause it to vibrate at a natural frequency. This can lead to structural failure if not mitigated through design modifications or control systems. Divergence occurs when the aerodynamic forces cause the aircraft's structure to deform in a way that reduces its stiffness, potentially leading to catastrophic failure. Control reversal happens when the aerodynamic forces on the control surfaces cause them to move in the opposite direction intended, compromising the aircraft's maneuverability.

Aeroelasticity is studied through a combination of theoretical analysis, wind tunnel testing, and computational simulations. Engineers use these tools to predict and mitigate aeroelastic effects, ensuring that aircraft are safe, stable, and performant. Advances in materials science and computational methods continue to improve the understanding and management of aeroelastic phenomena, contributing to the development of more efficient and reliable aircraft.
