What's Happening?
United Aircraft has successfully completed ground-vibration testing on the Yakovlev MC-21 prototype, which has been modified to replace foreign systems with domestically-built alternatives. This step is crucial for the aircraft's certification program, ensuring reliability and protection against resonant oscillations during flight. The tests were conducted at the final assembly plant in Irkutsk, focusing on the aircraft's hydraulics, power supply, integrated control system, undercarriage, and electronic equipment. The MC-21 chief designer, Vitaly Naryshkin, emphasized the importance of frequency testing in bringing the fully import-substituted airliner closer to its first flight. The prototype is set to be the baseline model for serial production, with around 220-230 test flights required for certification.
Why It's Important?
The completion of ground-vibration tests marks a significant milestone for United Aircraft and Russia's aerospace industry, which has been affected by international sanctions. By substituting foreign systems with domestic alternatives, Russia aims to reduce dependency on foreign technology and strengthen its aerospace capabilities. This development could enhance Russia's position in the global aerospace market, potentially leading to increased production and export opportunities. The successful certification and production of the MC-21 could also bolster domestic employment and technological innovation within the industry.
What's Next?
The MC-21 prototype is expected to carry out its maiden flight in August, as indicated by Russian state technology firm Rostec. Following this, the aircraft will undergo extensive flight testing, with approximately 220-230 test flights planned for its certification program. Preparations for serial production are underway, including updates to equipment at the Irkutsk final assembly line and training of maintenance specialists for the MC-21 and its Aviadvigatel PD-14 engines. These steps are crucial for ensuring the aircraft's readiness for commercial production and operation.
