The third Sukhoi Superjet 100 (S/N 95004) has completed cold-soak trials in Yakutsk, in Russia’s Far East, and returned to the Sukhoi Civil Aircraft Company (SCAC) flight-test center in Zhukovsky, the manufacturer announced today.
Yakutsk hosted successful warm-up runs after the jet sat parked for up to 17 hours in temperatures reaching -41 degrees C. The testing included a check of aircraft system performance and involved standard ground-servicing equipment. The airplane then conducted a total of seven test flights, demonstrating the smooth operation of all onboard systems. SCAC’s team also assessed the influence of short-term parking on aircraft availability for subsequent takeoff.
Upon receipt of the type certificate, SCAC plans to hold further trials to extend the temperature operational limits below -41 degrees C.
SCAC’s latest schedules call for Russian type certification of the Superjet 100 this summer and delivery of the first production airplanes to Aeroflot and Armavia by the end of this year.
