airfoils, plural;
  1. A structure with curved surfaces designed to give the most favorable ratio of lift to drag in flight, used as the basic form of the wings, fins, and horizontal stabilizer of most aircraft

  1. a device that provides reactive force when in motion relative to the surrounding air; can lift or control a plane in flight
  2. An airfoil (in American English) or aerofoil (in British English) is the shape of a wing or blade (of a propeller, rotor or turbine) or sail as seen in cross-section.
  3. A structure shaped to produce lift when moving in air; A wing of an aircraft
  4. a wing, kite, or sail used to generate lift or propulsion.
  5. A surface designed to produce lift from the movement of air over it. Ideally, it should present the greatest amount of lift with the least amount of drag.
  6. The Airfoil is the shape of the cross section of the wing. The front of the airfoil is the leading edge and is usually a rounded section. The back of the airfoil is the trailing edge and usually tapers to nearly a point. The distance between the two is the wing chord. ...
  7. the cross-section shape of a wing. Airfoils can be flat-bottomed, semi-symmetrical or symmetrical, depending on the style of airplane and what it needs to do. Also written as aerofoil, depending on which country you are in.
  8. A surface, such as an airplane wing, shaped to produce more lift than resistance when driven through the air.
  9. An object with a special shape that is designed to produce lift efficiently when the object is moved through the air. For example, the cross-section of a wing is an airfoil.
  10. The shape of any flying surface, but principally a wing, as seen in side view ("cross-section"). Its characteristics are Center of Pressure (CP), DRAG (CD), LIFT (CL), Lift-Drag Ratio (L/D), and Moment (CM).
  11. A curved body, such as a wing, that causes lift when air moves over it.
  12. the special curved shape of an airplane wing or helicopter rotor blade. The airfoil shape generates an upward force called lift.
  13. Any surface, as a wing or stabilizer, designed to aid in lifting or thrusting, controlling or stabilizing an airborne body or craft, by making use of the air currents through which it moves.
  14. Shaped or streamlined member at hood entrance designed to enhance movement of air into the hood.
  15. Any surface such as an airplane wing, aileron, or rudder designed to obtain a useful reaction from the air moving past it.
  16. The cross section profile of the leeward side of a wind generator blade. Designed to give low drag and good lift. Also found on an airplane wing.
  17. root: NACA 0018-64 mod; tip: NACA0009-64 mod (symmetrical)
  18. The aerodynamic, lift producing, profile of any flying wing.
  19. An aerodynamic device designed to improve traction by increasing the downforce on the car. The use of airfoils (also called wings) increases the cornering capability and improves stability at speed, but often at the expense of additional aerodynamic drag.
  20. A structure shaped to obtain an aerodynamic reaction in the air, thus affecting the performance of the aircraft.
  21. The shape of the wing when looking at its profile. Usually a raindrop type shape.
  22. a shape that creates lift. Often shaped like a wing.
  23. the cross-section shape of an aircraft’s wing. Another common spelling is aerofoil.
  24. An airfoil or aerofoil is a part or surface, such as a wing, propeller blade, or rudder, whose shape influences control, direction, thrust, lift, or propulsion.
  25. The shape of the blade cross-section, which for most modern horizontal axis wind turbines, is designed to enhance the lift and improve turbine performance.
