Vortex generators are small aerodynamic devices designed to improve the performance of vehicles, particularly aircraft and cars. They create small vortices, or swirling air patterns, that help maintain airflow over surfaces, reducing drag and increasing lift. This can enhance fuel efficiency and stability during flight or driving. Typically mounted on wings or body panels, vortex generators can be made from various materials, including plastic and metal. They are often used in aerospace engineering and automotive design to optimize performance and safety. By managing airflow, these devices contribute to better handling and overall efficiency.
