Definition
- Noun:
- A device that provides reactive force when in motion relative to the surrounding air; can lift or control a plane in flight: An aerofoil is a specially shaped surface, such as a wing, propeller blade, or rudder, designed to generate a desired aerodynamic force (like lift or control) as it moves through the air.
Usage and Examples
- Noun:
- The shape of the aerofoil is crucial for generating lift.
- Engineers tested a new aerofoil design in the wind tunnel.
- The horizontal stabilizer uses an aerofoil section to control the aircraft's pitch.
Advanced Usage
- "Aerofoil section" or "aerofoil profile": Refers to the specific two-dimensional cross-sectional shape of the wing or blade.
- The paper analyzed the pressure distribution over the aerofoil section.
- "Aerofoil theory": The branch of aerodynamics concerned with the properties and performance of aerofoils.
- His research contributed significantly to modern aerofoil theory.
Variants and Related Words
- Airfoil (noun): The American English spelling of 'aerofoil'. Both terms are identical in meaning.
- The NACA airfoil series is widely used in aviation.
- Camber (noun): The curvature of an aerofoil's upper and lower surfaces.
- Increased camber generally increases lift at lower speeds.
Synonyms
- Wing section: Specifically refers to the aerofoil shape of a wing.
- Control surface: A type of aerofoil used for steering (e.g., aileron, elevator).
Related Technical Terms
- Lift: The upward force generated by an aerofoil.
- Drag: The resistance force an aerofoil encounters moving through air.
- Angle of attack: The angle between the aerofoil's chord line and the oncoming air.
