  "term": "Foil",
  "field": "Industrial and trades",
  "definition": "The cross-sectional shape of a wing, propeller blade, or rotor blade designed to generate an aerodynamic force when moving through the air. Its curved upper surface and flatter lower surface cause air to travel faster over the top, creating a pressure differential that produces lift. The specific geometry of a foil is defined by its camber, chord, and thickness, with standardized shapes cataloged in systems like the NACA airfoil series.",
