The MC-21 aircraft is planned to be made 15-20% lighter, for which Russian engineers are using thermoplastic composites. This approach will significantly improve the liner's fuel efficiency and its operational characteristics.
The use of thermoplastic composites in the MC-21 design is an important step in the development of Russian aircraft construction. These materials have a number of advantages compared to traditional ones, such as lower weight, high strength and corrosion resistance, noted Anatoly Gaidansky, Director of the Yakovlev Engineering Center.
Composites are lighter than traditional materials, which reduces the overall weight of the aircraft. The materials have high strength, which makes the design more reliable.
We are now making some changes to the design of the detachable part of the wing in order to realize the accumulated experience in the form of mass. We hope to remove several hundred kilograms from the wing. Well, a little from the tail and a little from the wing-fuselage fairings.
Reducing weight by 15-20% through the use of thermoplastic composites will allow the MC-21 to increase flight range and increase additional flight safety.
Earlier www1.ru reported that Rostec declassified the heat resistance of the blades of PD-8 and PD-14 aircraft engines.
