Computational Fluid Dynamics (CFD) and Static Structural Analysis (FEA) of an Aircraft Wing
Journal Title: Libyan Journal of Engineering Science and Technology - Year 2024, Vol 4, Issue 1
Abstract
In this study a CFD and static structural analysis of an aircraft wing have been carried out. An aircraft wing has been designed and modelled via the software SolidWorks and subsequently, structural analysis is carried out in ANSYS using pressure loads extracted from the performed CFD simulations. Numerous aerodynamics and static structural analysis results have been shown and a comprehensive comparison of results for two different materials for wing construction has been presented. Pressure and velocity fields, pressure coefficient, total deformations and stresses are calculated and presented. The proposed design of the wing has been found safe under the applied flight condition loads. The maximum total deformation arrives to 0.00377 m for the wing with aluminum spars, whereas for the wing with steel spars is found 0.00331 m. The maximum principal stress is found equal to 3.92e7 Pa for the aluminum spars wing, whereas for steel spars wing its maximum value up to 3.3e7 Pa. Stresses are not close to the yielding stress of materials of the wing. It has been therefore concluded that steel spars of wing are safer compared to the aluminum spars, however the advantage of aluminum alloy is higher strength to weight ratio.
