Airfoil (Noun)
Meaning
A device that provides reactive force when in motion relative to the surrounding air; can lift or control a plane in flight.
Classification
Nouns denoting man-made objects.
Examples
- The curved upper surface of an airplane wing is a classic example of an airfoil, providing lift as air flows over it.
- The helicopter's rotor blades are essentially airfoils, generating lift and allowing the aircraft to rise into the air.
- The airfoil shape of the sailplane's wing enables it to stay aloft for hours, using rising air currents to stay airborne.
- The racing car's spoiler is essentially an airfoil that provides downward force on the rear axle, improving handling and stability at high speeds.
- During flight, the airplane's control surfaces, including the ailerons and elevators, act as airfoils to control roll, pitch, and yaw.
