1. An aircraft structure comprising:
an aircraft structural component having a first outer surface, and
a set of reinforcing straps for reinforcing the aircraft structural component, wherein the set comprises:
a first reinforcing strap having an inner and outer surface, wherein the inner surface is attached to the outer surface of the aircraft structural component such that the first reinforcing strap extends longitudinally along the aircraft structural component,
a second reinforcing strap having an inner and outer surface, wherein the inner surface is attached to the outer surface of the first reinforcing strap and the inner surface does not contact the outer surface of the aircraft structural component such that the second reinforcing strap extends longitudinally along the first reinforcing strap,
wherein over at least a portion of the length of the reinforcing straps, the second reinforcing strap has an average thickness between the inner and outer surfaces of the second reinforcing strap that is larger than the average thickness of the first reinforcing strap between the inner and outer surfaces of the first reinforcing strap,
wherein the thickness of the first reinforcing strap varies along its height,
wherein the aircraft structural component is a stringer, and
wherein the aircraft structure further comprises a rib extending across the stringer and wherein the rib is provided with a hole for the stringer to pass through and wherein the reinforcing straps also pass through the hole.
