About: Foil (fluid mechanics)

An Entity of Type: planet, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

A foil is a solid object with a shape such that when placed in a moving fluid at a suitable angle of attack the lift (force generated perpendicular to the fluid flow) is substantially larger than the drag (force generated parallel to the fluid flow). If the fluid is a gas, the foil is called an airfoil or aerofoil, and if the fluid is water the foil is called a hydrofoil.

  • A foil is a solid object with a shape such that when placed in a moving fluid at a suitable angle of attack the lift (force generated perpendicular to the fluid flow) is substantially larger than the drag (force generated parallel to the fluid flow). If the fluid is a gas, the foil is called an airfoil or aerofoil, and if the fluid is water the foil is called a hydrofoil. (en)
  • En mécanique des fluides un foil est une aile positionnée et profilée de façon à engendrer, par son déplacement dans l'eau, une force de portance qui agit sur sa vitesse et sa stabilité. (fr)
