Another phase of endurance tests of extended-range Sukhoi Superjet 100 airframe has been completed in the Central AeroHydrodynamic Institute named after N.E. Zhukovsky (TsAGI). TsAGI‘s specialists implemented 12.000 flight cycles, i.e. recreated on the ground the periodic loads occurring during take-off/ landing, cruising and nonflight modes. The tests have confirmed high reliability of a new modification of the Russian airliner during initial phases of its operation.
Endurance tests of Sukhoi Superjet 100 airframe with extended range of 4.578 km will be performed during next several years. During this period of time it is planned to simulate 162.000 flight cycles in order to confirm the design service life of 54.000 flights in relation to load carrying structure of RRJ family aircraft.
It bears reminding that RRJ-95LR-100 A/C was delivered in a disassembled state to Zhukovsky in the end of 2014. During 2015 joining of outer wings and fins to the fuselage and construction and mounting of the special-purpose test stand was carried out, as well as preparation works and first stage of endurance tests were performed in TsAGI.
Sukhoi Superjet 100 is a new generation regional jet featuring state-of-the-art technologies of the aircraft industry. SSJ100 boasts enhanced comfort for the passengers, favorable economic benefits for the air carriers and maximum environmental safety. Cooperation of TsAGI and Sukhoi Civil Aircraft Company has started in 2001. The whole range of aerodynamics and endurance tests, A/C control system tests has been implemented by the Institute. SSJ100 extended-range variant is designed for air transportation of passengers at the distance of up to 4.578 km.
