The successful use could also be verified for 2×2 m section demonstrators in a package. This way the heating time could be shortened from 2 to 1 hours under the compliance of the sufficiently exact temperature distribution – and that’s by only 5% of the oven energy! The result is an even ecological as well as an economical advancement.
For the rear section of the pressure cell of an airplane – the front end measuring 3 m spherical segment was joined from 2 parts using friction stir welding and transformed by creep forming.
Further sampling using heating mats are in packages and for original 10 x 2 Meter in size complex formed skins with hold-down clamps planned and are taking place at the technology center in Nordenham.
AlMgSc is a superior aluminium alloy which through proven innovative technology and clearly cheaper forming costs is compensating a significant part of the material costs, a specific implementation option for a clearly more lightweight metal plane.
