A single piece co-cured composite wing is disclosed. The wing has a flying surface
and structural members. In one embodiment the structural members may be a plurality
of spars. The spars may have various shapes to increase the buckling strength.
The spars may be wave shaped, such as a sinusoidal shape. The flying surface and
the structural members are co-cured in order to form a single piece, integral wing
structure. A process for manufacturing a single piece co-cured wing is also disclosed.
The process may include laying out composite sheets for the flying surface of the
wing. Then, the composite material of the spars is arranged around a plurality
of pressurizable forms. Finally, the composite material is cured in a clamshell frame.
