What is it about?
This article explores state-of-the-art methods to modify the shape and material thicknesses of aircraft wings while retaining structural integrity and adhering to constraints imposed by manufacturing processes and overall aircraft design. Specifically, a benchmark test case was optimized, which was proposed to compare different institutions' numerical methods. Fuel burn, which was used as the objective, was reduced by increasing the aspect ratio and decreasing the wing profile thickness.

Why is it important?
We present methodologies to predict aircraft performance in the early stages of aircraft design, aiding in the evaluation of unconventional aircraft configurations.
Perspectives
We must establish automated end-to-end processes for designing aircraft wings to accelerate aircraft development. Implementing these capabilities reduces CO2 emissions and increases economic efficiency.
