airfoil
er faw il
- n a device that provides reactive force when in motion relative to the surrounding air; can lift or control a plane in flight
- Cause is an area of excessively compressed air, built up by the airfoil's passage.
- Once he had learned that air, moving over a still airfoil, also generates lift, Custer went on to investigate the principle of the Venturi tube.
- He showed the airfoil to a pilot friend, Floyd Fogleman, who concluded that Kline had inadvertently discovered "a whole new concept in aerodynamics.
