Specialists of the Zhukovsky Central AeroHydrodynamic Institute (TsAGI, a member of the National Research Center “Zhukovsky Institute”) completed one more stage of the Sukhoi Superjet 100 airframe endurance tests by undertaking 24 000 flight cycles. The aircraft was tested under multiple loads corresponding to all flight modes: takeoff and landing, cruise and ground.
The RRJ-95LR-100 model structure was the object of the tests. It is an extended-range version of up to 4578 km. According to the specialists of the Institute, the tests confirmed the initial reliability of the aircraft structure.
It is planned to simulate 162 000 flight cycles to prove a design life of 54 000 flights for the main load-carrying structure of the RRJ aircraft. The work was started in 2015 and will last for several more years.
Cooperation between Sukhoi Civil Aircraft and TsAGI within the framework of the Sukhoi Superjet 100 Project has been ongoing since 2001.
During this time, Institute specialists implemented a wide range of studies of aerodynamics, strength and control systems for the domestic aircraft.
