Airfoil
by Bartosz Ciechanowski
Summary
The article “Airfoil” by Bartosz Ciechanowski is an interactive, physics-based exploration of how wings generate lift by shaping airflow. It explains that lift is not caused by a simple path-length difference between air traveling over and under a wing, but by a coupled system of airflow velocity, pressure differences, and the geometry of the airfoil. Using visual simulations, it shows how an object moving through air creates regions of varying pressure, and how these pressure gradients produce forces that can balance gravity for an airplane.
The article further builds intuition by introducing key fluid dynamics ideas such as relative motion, pressure fields, viscosity, boundary layers, and the Reynolds number, illustrating how different flow regimes (laminar vs turbulent) emerge depending on conditions. Overall, it connects microscopic particle interactions and pressure gradients to macroscopic flight, showing how carefully designed airfoil shapes manipulate airflow to produce stable lift.
