Korean Air Aerospace Division has become a partner in Airbus's Wing of Tomorrow programme aimed at developing manufacturing methods for a composite wing on a future A320-family replacement.
The airline says that its aerospace arm will participate in the development of "innovative composite structures" for the demonstrator programme under a co-operation and research agreement that was signed with Airbus on 19 June.
Airbus and its partners are in the process of assembling an initial 5m (16ft) demonstrator and have plans to manufacture three full-scale demonstrators in 2020.
The Wing of Tomorrow programme is scheduled for completion by early 2022.
Korean Air Aerospace Division has been a supplier for A320 winglets for 10 years, and was selected in 2016 to produce winglets for the A330neo, Korean Air notes.
The manufacturer additionally manufactures winglets for Boeing 737s, and fuselage and wing structures for the 787 programme.
