Aeroelastic dynamic and stability of a folding fin with freeplay nonlinearities

Key Points

• Aeroelastic behavior significantly influences dynamic stability under variable conditions, and freeplay nonlinearities present challenges.
• Key insights show that changes in the folding fin's design impact stability metrics, enhancing performance by 30%.
• Assessment using theoretical models and simulations examines various non-linear effects and their interactions in aeroelastic systems.
• This highlights the need for innovative design approaches to manage stability problems associated with folding fins at high maneuvers.
