Fatigue strength estimates for composite wing panels of prospective supersonic transport aircraft

Implementation of the Methodology of Coupled Modelling of Aerodynamics and Strength to Determine the Onset Speed of the Bending-Torsional Flutter of the Wing Console

“…To construct a finite element model, the original geometric characteristics were preserved, and the equality of stiffness values was ensured by the reduced properties of the material [3] To simulate the constraints, an encastre was used on the side of the wing root chord [4]. The model consists of two finite element grids: a structural-power mesh, necessary for the perception of external loads [5], and an aerodynamic mesh, necessary for obtaining external aerodynamic loads and transferring them to a structural-power mesh [6].…”
