The combined results demonstrate that implementing a one-way aero-structural coupling approach better predicts loading accuracy and the resultant structural response, giving a more reliable basis for preliminary aircraft wing design.
Abstract
In this work, an integrated aero-structural methodology is presented, combining a MATLAB panel-method aerodynamic solver with ANSYS finite-element analysis to predict the performance of a tapered NACA 2412 wing. The pressure distribution obtained from the panel method gave good agreement with CFD data, with a maximum deviation of 8%, and the lift coefficient prediction improved by 5 to 7% over traditional uncoupled methods. Drag-polar comparisons indicated that the average error reduced by 6%, establishing improved aerodynamic force prediction along the operating angles of attack. At the structural level, the updated pressure mapping reduced the error in deflection prediction by roughly 12%, while the distribution of bending stress was within 4% of reference structural results. These combined results demonstrate that implementing a one-way aero-structural coupling approach better predicts loading accuracy and the resultant structural response, giving a more reliable basis for preliminary aircraft wing design.
Winglets are aerodynamic devices that reduce induced drag by mitigating wingtip vortices, thereby improving aircraft fuel efficiency and overall performance. This study presents a comparative computational investigation of the aerodynamic performance of wings with NACA 2412 (cambered) and NACA 0012 (symmetric) airfoils...

Finite element simulation is a crucial tool for strength analysis of civil aircraft wing structures, imposing stringent requirements on accurate nodal load application. Wing surface loads are typically provided as spatial curved surface pressure distributions (CP) at aerodynamic grid points, which cannot be directly ap...
The application of composite materials on aircraft wings can not only enhance the structural stiffness of the wing, reduce the weight of the wing, but also decrease the number of mortise-and-tenon joints in the wing structure, resulting in a smoother wing surface and improved aerodynamic performance of the aircraft. In...
