National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Fabrication of Test-Articles from Al-Li 2091 for Fokker 100.

ADP005930

Publication Date	1989
Personal Author	Vaessen, G. J.; Tilborgh, C.; Rooijen, H. W.
Page Count	12
Abstract	The technical requirements for introduction of Aluminium-Lithium-alloys in secondary structures of aircraft are formulated. The general corrosion behaviour, stress-corrosion properties and mechanical properties of the alloy 2091-T3 from Cegedur-Pechiney meet these requirements. The successful fabrication of access doors in the underwing fairing of the Fokker 100 is described. The same manufacturing techniques as for 2024 can be used for 2091, i.e. machining, blanking, bending, chemical milling, surface pretreatments, adhesive bonding, solution heat treatment and drop hammer forming, stretch forming, painting and rivetting. Operational in-service trial on Fokker 100 and F28 operated by major airlines as Swissair and Garuda has started.
