Fig. 7: Design of variable thickness wing.

a The crease pattern of a variable thickness wing consists of tessellations of five Miura-origami units. The unit geometry can be designed by changing side a. b Snapshots (the permanent and temporary shapes) of the variable thickness wing. Scale bar, 40 mm. c Experimental demonstration of different modes of the variable thickness wing obtained by changing heating time. Scale bar, 40 mm. d Variation of airfoils of the variable thickness wing with different geometric designs. e One airfoil can be represented by the peak point coordinates (L is the wing extension). Scale bar, 20 mm. f Design space of the variable thickness wing.
