wingShellType

The upper and the lower shell are the outer surface of the component segment above and below its chord surface. <skin> and <stringer> hold for the whole shell; a cell (<cells>) gives a region of it a skin and stringers of its own.

Stringers do not have to be given as parts of their own: a skin of a composite material can carry them as an equivalent layer instead.
