Default RE: Airfoils

ORIGINAL: WS

The chord x span = area
The greater the chord for a given thickness, the greater the frontal area (and wing area)

For a given thickness, how does increasing the chord increase the frontal area? It will certainly increase the wing area (wetted surface) ------ but frontal area???

Are you referring to a frontal area increase because of exposed under-wing surface at some angle of attack? At zero AOA, for example, I don't see how a change in chord can affect frontal area.
