This was a fun-filled hour of demonstrations, videos and explanations about things that spin. Dr. Duque is a research scientist who uses computers to study the aerodynamics of helicopters, rotorcraft, and wind turbines. You will learn about lift and angle of attack by watching this archive. Lift is a force that is perpendicular to the airflow around an aircraft. Engineers design airplanes so that the lift created by the airfoil opposes the weight force.
Angle of attack refers to the angle of an airfoil to the oncoming airflow.
