Wing unit airfoil structure

摘要

The wing unit (12) has a ridge (6) bulging outwardly in a top skin (4), and a ridge (7) bulging in a bottom skin (5). The ridges begin in an area (9) of a trailing edge (2), and extend toward the leading edge (1) in the direction of a depth axis (8). Each ridge has a height that is largest in the trailing edge area, and diminishing from the trailing edge area toward the leading edge. The top skin and bottom skin are supported by an inner structure between the trailing and leading edges. The depth axis extends perpendicularly to and between the leading and trailing edges.
