The Irkut MC-21’s polymer-based composite wing box has been delivered to the Central Aero-Hydrodynamic Institute (TsAGI) on the outskirts of Moscow and is set to begin static testing.
A special wing box test-stand was built in TsAGI to implement the test programme as this is the first time a composite structure of this size has been created and tested in Russia. It was manufactured by the AeroComposite-Ulyanovsk plant and delivered to the TsAGI by road transportation.
Extensive use of composite materials manufactured according to unique Russian technologies has been implemented with the aim of giving the MC-21 a flight performance advantage over other aircraft in its class.
Currently, assembly of the second MC-21 aircraft is nearing completion at Irkut Corporation’s plant in Irkutsk, where the first prototype was unveiled on 8 June 2016.
