The Kármán–Trefftz airfoil

The Kármán–Trefftz airfoil is a specially shaped design used in aerodynamics to control airflow around wings. It consists of a smooth, curved upper surface and a flatter lower surface, optimized to reduce drag and improve lift. These aerodynamic features help aircraft generate lift efficiently while minimizing energy loss during flight. The design balances theoretical principles with practical considerations, making it effective for various flying conditions by improving stability and performance. In essence, it's a carefully crafted wing shape that enhances how air moves over its surface, leading to more efficient and stable flight.
