In this paper the design of spinal structures for the control of
morphing airfoils is examined. The aim is to find structures that,
when suitably loaded, can alter the aerodynamic shape of a
cladding that forms the airfoil. Morphing through different
cambered airfoils to achieve aerodynamic properties for different
maneuvers is then possible by exploiting a range of incremental
non-linear structural solutions. Further, by using structures that
are acting in the post-buckling regime, it is possible to obtain
significant changes in shape with only modest changes in applied
load. The structure also presents enhanced aeroelastic properties.
Results are formulated in terms of the aerodynamic properties of
the morphed airfoils using a shape optimized beam as the spinal
structure with fixed aerodynamic cladding.
