What is a curved airfoil?

A curved airfoil is a specialized wing shape designed to generate lift when air flows over it. Its curvature allows for a difference in air pressure between the upper and lower surfaces, creating lift due to the Bernoulli principle and Newton's third law of motion. Curved airfoils are commonly used in aircraft wings and blades of turbines, enhancing aerodynamic efficiency and performance. The design can vary based on the specific application and desired flight characteristics.
