Which term denotes the curved part of an airfoil from its leading edge to trailing edge?

Which term denotes the curved part of an airfoil from its leading edge to trailing edge?

• A. Chord
• B. Leading edge
• C. Camber
• D. Relative wind

Answer: (C)

Camber is the curvature of the airfoil's centerline as it runs from the leading edge to the trailing edge. It describes how far that mean line arches away from the straight chord line (the straight line from front to back). This curvature is what gives the airfoil its lift without necessarily changing the overall size—the chord is the straight distance between leading and trailing edges, the leading edge is the front edge, and relative wind is the direction of the oncoming air. So the curved part from front to back is camber.
