A morphing wing for an aircraft, comprising: a top surface, a bottom surface, a leading edge, a trailing edge, a tip, and a root, wherein the root is adapted for connection to the aircraft, a plurality of structural ribs (76,78) disposed between the root and tip, wherein the structural ribs (76,78) extend between the top surface and the bottom surface; four active members (88,90,92,94) connected between adjacent first and second structural ribs (76,78) of the plurality of structural ribs (76,78), the four active members (88,90,92,94) being actively adjustable, characterised in that a first and second active member (88,90) of the four active members (88,90,92,94) attach to the first structural rib proximate each other at a first position; a third and a fourth active member (92,94) of the four active members (88,90,92,94) attach to the first structural rib proximate each other at a second position; the first active member and the third active member attach to the second structural rib proximate each other at a third position; and the second active member and the fourth active member attach to the second structural rib proximate each other at a fourth position; and at least one passive member (80,82,84,86) connected between the adjacent first and second structural ribs (76,78), wherein the at least one passive member (80,82,84,86) is passively adjustable; wherein adjustment of at least one of the four active members (88,90,92,94) moves the adjacent first and second structural ribs (76,78) with respect to one another, thereby morphing the wing from a first configuration to a second configuration. a top surface, a bottom surface, a leading edge, a trailing edge, a tip, and a root, wherein the root is adapted for connection to the aircraft, a plurality of structural ribs (76,78) disposed between the root and tip, wherein the structural ribs (76,78) extend between the top surface and the bottom surface; four active members (88,90,92,94) connected between adjacent first and second structural ribs (76,78) of the plurality of structural ribs (76,78), the four active members (88,90,92,94) being actively adjustable, characterised in that a first and second active member (88,90) of the four active members (88,90,92,94) attach to the first structural rib proximate each other at a first position; a third and a fourth active member (92,94) of the four active members (88,90,92,94) attach to the first structural rib proximate each other at a second position; the first active member and the third active member attach to the second structural rib proximate each other at a third position; and the second active member and the fourth active member attach to the second structural rib proximate each other at a fourth position; and at least one passive member (80,82,84,86) connected between the adjacent first and second structural ribs (76,78), wherein the at least one passive member (80,82,84,86) is passively adjustable; a first and second active member (88,90) of the four active members (88,90,92,94) attach to the first structural rib proximate each other at a first position; a third and a fourth active member (92,94) of the four active members (88,90,92,94) attach to the first structural rib proximate each other at a second position; the first active member and the third active member attach to the second structural rib proximate each other at a third position; and the second active member and the fourth active member attach to the second structural rib proximate each other at a fourth position; and at least one passive member (80,82,84,86) connected between the adjacent first and second structural ribs (76,78), wherein the at least one passive member (80,82,84,86) is passively adjustable; wherein adjustment of at least one of the four active members (88,90,92,94) moves the adjacent first and second structural ribs (76,78) with respect to one another, thereby morphing the wing from a first configuration to a second configuration.
