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, ...

The following question, "How does an airfoil create lift?" comes from Ms. Gillespie's class. I love watching airplanes take off at the airport. I think it’s an amazing feat of human engineering that ...

Humanity has long been obsessed with heavier-than-air flight, and to this day it remains a topic that is shrouded in a bit of mystery. In this video we take a detailed look at lift, starting with how ...

A team of evolutionary biologists and engineers have demonstrated a new structure inspired by shark skin that could improve the aerodynamic performance of planes, wind turbines, drones, and cars. The ...

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 ...
