The Scientific Research Department of Strength at PJSC Yakovlev is responsible for the strength of the new SJ-100 Superjet aircraft body. In total, it employs 48 people, including one Doctor of Science and two Candidates of Technical Sciences.
Specialists conduct dynamic and static calculations, ensuring the strength of the standard design of the aircraft and its units during design, production, testing and certification.
Engineers ensure the structural strength during long-term operation by performing calculations for survivability and fatigue, and maintain compliance of the aircraft with the requirements of airworthiness standards.
They perform calculations to determine external loads acting on the structural elements of the airframe, calculations to determine fatigue loads, and also analyze the results of flight tests and monitor the load on the Superjet fleet.
Earlier www1.ru reported that the MS-21 aircraft flew for the first time to test navigation systems as a regular aircraft.
