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 ...

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 ...

As the angle of attack is increased on a high-performance airfoil, a small amount of separation occurs near the leading edge. This separation causes the boundary layer to transition from laminar to ...

Combined flow control accessory effectively improves the lift coefficient of the airfoil in the pre-stall and post-stall region. Journalists may use this image only with appropriate credit.

The NACA 23012, designed in 1935 by Eastman Jacobs, is possibly the most widely used airfoil in history. Its widespread adoption is attributed to its excellent performance characteristics, which ...
