In the published article, incorrect versions of three figures (Figs 19, 22 and 23) were displayed. The published article has now been updated to show the correct figures.
Also, in the last paragraph of the Conclusion, a sentence that originally read:
“It must/needs to be analysed how the structure can be modified depending on maximum loads and how this eventually affects the weight and efficiency of the aircraft must also be analysed.” has now been amended to read:
“It must be analysed how the structure can be modified depending on maximum loads and how this eventually affects the weight and efficiency of the aircraft.”
The publishers would like to apologise for these errors.
