Tip-mounted devices

Definition

Tip-mounted devices are aerodynamic structures placed at the wingtips of an aircraft to enhance performance by reducing drag and improving fuel efficiency. These devices include winglets and other forms that help mitigate the induced drag caused by wingtip vortices, which can significantly impact the overall aerodynamic efficiency of an aircraft. By optimizing airflow around the wings, tip-mounted devices contribute to improved lift-to-drag ratios and overall flight performance.
