"Today, the MC-21-300 plane with a wing produced from Russian-made polymer composite materials has performed its first flight. The plane took off from the Irkutsk Aviation Plant airstrip. The flight proceeded as planned," the company said.
The domestic materials for the wing’s bearing frame were developed in cooperation between Rosatom, Moscow State University scientists, and aviation industry specialists.
According to Rostec CEO Sergey Chemezov, the share of composite materials in the MC-21 plane is about 40%, which is the record high for planes of this class.
