Optimal design of composite wing subjected to gust loads

Aeroelastic Tailoring of a Representative Wing Box Using Tow-Steered Composites

“…shown that the application of aeroelastic tailoring may lead to significant overall aircraft performance improvements in terms of reduced weight, reduced drag, reduced aerodynamic gust loads and higher flutter/divergence instability airspeeds [4][5][6][7][8][9], by concurrently optimizing the structural and aerodynamic behaviors. The improvement in wing static and/or dynamic behavior in different airflows is typically achieved by adjusting the wing stiffness and the coupling between wing bending and torsion deformations.…”

Optimization of Tow-Steered Composite Wing Laminates for Aeroelastic Tailoring

“…It was first demonstrated on the X-29 experimental aircraft, where a washout effect (wing up-bend coupled to nose-down twist) was used to increase the divergence speed of the forward-swept wing [1,2]. Other aeroelastic tailoring objectives include: weight reduction [3], drag reduction [4], improved gust response [5,6], optimum flutter characteristics [7], and combinations thereof [8][9][10]. All of these typically involve modifying the stiffness of the wing and the passive elastic coupling between wing bending and torsion deformations, such as to improve the static and dynamic wing behavior in different airflows.…”

Impact of the Wing Sweep Angle and Rib Orientation on Wing Structural Response for Un-Tapered Wings

“…Such control has been principally achieved through the use of composite materials where the stiffness tailoring is achieved through the control of the fibre orientation [4][5][6][7][8][9] . More recently research work has focused on the use of the wing structure shape and arrangement to improve aeroelastic properties [10][11][12][13][14][15][16][17][18][19][20][21][22][23] .…”
