Without the aerodynamic forces of lift and drag, aircraft would be unable to fly, wind turbines would not spin, and countless other machines that we depend on every day would not work. What, exactly, ...

We’ve probably all experimented with a very clear demonstration of the basic principles of lift: if you’re riding in a car and you put your flattened hand out the window at different angles, your hand ...

Illustration of the airflow along an airfoil that exhibits leading-edge stall behavior. Notice the formation of a “short bubble” at a critical point along the leading edge. When the AOA is increased ...
