Thin airfoil theory

Thin airfoil theory is a mathematical model used in aerodynamics to predict the behavior of very thin wings (or airfoils) at small angles of attack. It simplifies the complex interactions between airflow and the wing shape by assuming the wing is so thin that its thickness is negligible. This theory helps in understanding how air flows over the wing, contributing to lift generation. It is particularly useful in designing aircraft wings, allowing engineers to calculate important properties like lift and drag efficiently, while offering insights into how changes in shape can affect overall performance.
