All-metal aircraft - Ganzmetallflugzeug
The outer skin of the aircraft absorbs forces and transmits them so that an all-metal aircraft only needs a light load-bearing structure. Due to this so-called half - shell construction , all-metal aircraft have a lower weight than aircraft in wood or composite construction despite the use of relatively heavy materials .
This construction was first used by Hugo Junkers with the Junkers J 1 , which took off on December 12, 1915 with Friedrich von Mallinckrodt on its maiden flight. Junkers still used steel as the outer skin of the J 1 and J 2 , but for weight reasons switched over to paneling with light metals such as duralumin for subsequent models such as the J 7 , which subsequently became the norm in metal aircraft construction. Junkers built several all-metal aircraft during the First World War , including the first series-produced all-metal aircraft J 4 ( IdFlieg-Specification "JI"); However, the breakthrough came in 1919 with the J 13 , the first all-metal aircraft in civil aviation, which was used throughout the world and of which 320 units had been built by 1932.
