On November 6th 2014, the airframe of Sukhoi Superjet 100LR (Long Range) aircraft was delivered to the Central Aerohydrodynamic Institute named after professor N.E. Zhukovsky (TsAGI), in order to carry out endurance testing, press-service of Sukhoi Civil Aircraft Company (SCAC) reports.
“The SSJ100 aircraft, certified model RRJ-95LR-100, MSN 95075, was delivered in knocked down condition by the An-124 “Ruslan” to the Ramenskoye airfield, located in Zhukovsky (Moscow Region). Fuselage, wings and empennage will soon be joined and the airframe will be fitted with special system used to impose load as well as measuring sensors,” the company noted.
”During the endurance testing, all the primary structural elements of the aircraft will be checked under different loading conditions corresponding to all flight conditions, including turbulence,” Chief Designer of SCAC Vladimir Lavrov said. “The test results should confirm both the claimed aircraft service life and the program of maintenance checks developed for this aircraft type”.
We remind you that in 2013, the Aviation Register of the Interstate Aviation Committee (IAC AR) certified the Long Range version of Sukhoi Superjet 100 aircraft and confirmed its compliance with IAC AR regulations. This fact allowed Russian carriers to start the operation of the SSJ100 LR jet. At present the company is working on European Aviation Safety Agency (EASA) certification for the Long Range version of Sukhoi Superjet 100.
The endurance testing should confirm the designed service life of Sukhoi Superjet 100 LR aircraft: 70 000 flight hours and 54 000 cycles, SCAC noted.
SCAC and TsAGI have been working in close cooperation in the network of Sukhoi Superjet 100 project since 2001. One of the largest scientific research centers was used to carry out static tests of SSJ100 airframe (MSN 95002) and specific aircraft components. The same center also carried out studies on the aircraft’s aerodynamics using wind tunnels.
Besides longer range (compared to basic version), the aircraft has an increased takeoff weight – up to 49.45 tons and reinforced wing (in order to compensate the increased takeoff weight). This version of SSJ100 is powered by SaM146-1S18 engine having 5% more thrust, SCAC added.
