A thin sheet curved convex up has an upper side and a
lower side; the curve of the lower side is the intrados; some uses move
further on the term and identify the material skin for that underside as
the intrado or intrados. Similarly for the upper curve as extrados with
some moving the term into a use that identifies the material skin of the
curved item as the extrado or extrados.
An idealized curved line has extrados and
intrados; such idealized line has no material skin. A wing that is
curved has a top curve and a lower curve; the curves are sometimes
referred to as extrados and intrados, respectively. If material skins
are used for those curves, some identify the material skin used as
extrados and intrados, respectively. Dropping the "s" is done by some
users: extrado or intrado, respectively.
The XXLite's upper surface curve is an idealized
curve; the material forming he skin of that upper surface may by some
users be called the extrados or extrado. The XXLite has two sectors to
its airfoil in the lower region; the frontal sector of the airfoil in
the lower region has a curve when loaded in flight; such curve is
skinned using contiguous material that flows to the top surface; the
skin on that lower surface frontal section may be referred by some users
as the intrados or intrado of that wing for the frontal lower sector.
Then the wing has a large aft lower curve that is the intrados of the
wing for that larger aft section of the wing; the material skin of that
aft intrados, if already specified as the skin of the extrados, then one
may say that a second skin is not used for the aft sector of the
intrados; some will say then that there is no intrados for that aft
section of that wing; but indeed the curve is there and the skin is
there; it is just that the same material skin is used for both the
curves: the extrados and the intrados, if one neglects to see that the
actual curves are actually finely distinct. The ordinary goal of
the distinctions is to sort that in the aft section of the wing, only
one material sheet of cloth is used to effect both the extrados and
intrados; that sheet of cloth has an upper side or upper surface and a
lower side or lower surface; those surfaces have curves to them that are
finely distinct. For related matter, see KFm airfoils.
