Abstract
A closed shear flexible panel has upper and lower surfaces each having front ends which define a leading edge and rear edges which define a trailing edge. The rear edges are slideable longitudinally with respect to each other when a torsional force is applied to the panel or a linear force is applied to the rear edges to induce a spanwise gradient pitch in the panel.
Claims24
A shear flexible panel which comprises:
- a longitudinally extending upper surface having a first longitudinal front end;
- a first longitudinal rear edge and a first inner face;
- a longitudinally extending lower surface having a second longitudinal front end, a second longitudinal rear edge and a second inner face;
- wherein said first and said second inner faces cooperate to define an interior cavity;
- wherein said first and second front ends cooperate to form a leading edge and said first and second rear edges cooperate to form a trailing edge;
- and
- wherein said first and said second rear edges are slidable longitudinally with respect to each other when one of a torsional force is applied to said panel or a linear force is applied to at least one of said first and second rear edges to thereby induce a spanwise gradient twist extending longitudinally in said panel.
