A new aircraft wing is up to 5 percent lighter than that of the current Boeing 777. This means that fuel consumption can be reduced by up to 200 tonnes.
A group of researchers from the DTU technical university in Denmark designed the optimal wing for a Boeing 777.
The wing is up to 5 percent lighter than the current wings, which can result in a fuel saving of 40 to 200 tons per year.
The wing is built in a 3D program that is 200 times as detailed as industrially used programs.

The researchers made the program themselves and used a supercomputer with access to 8000 processors for five days to develop the wing.
The program helps to find the structures that are strongest in relation to a concrete load and use as little material as possible.
The result is not only interesting for the aircraft sector, but also for the 3D printer industry, as it paves the way for printing larger, more complex structures.

The researchers designed the light wing using a 3D program that uses a resolution that is 200 times as high as the current standard.
- INSPIRATION FROM NATURE: The internal structure of the wing is reminiscent of certain structures in nature, for example in bones or beaks.
- 5 PERCENT LIGHTER WITH ALUMINUM: If the wing is printed in aluminum, it is 5 percent lighter than the wings of a Boeing 777.
- MORE PLACE FOR FUEL: A large part of the fuel is stored in the wings. The new wing therefore has more room for fuel.
