Abstract

Aeroelastic performance controls wing shape in flight and its behaviour under manoeuvre and gust loads. Controlling the wing's aeroelastic performance can therefore offer weight and fuel savings. In this paper, the rib orientation and the crenellated skin concept are used to control wing deformation under load. The impact of varying the rib/crenellation orientation, the crenellation width and thickness on the tip twist, tip displacement and natural frequencies are investigated. Various wind-off and wind-on loads are considered through Finite Element modelling and experiments, using wings manufactured through polyamide laser sintering. It is shown that it is possible to influence the aeroelastic behaviour using the rib and crenellations. Reasonable comparison between the numerical and experimental results was found.
