Industry Sukhoi completes Superjet 100 Saberlets flight test program
Russian aircraft manufacturer Sukhoi has released that it has completed its flight test program for the Superjet 100 with Saberlets.
At the aerodrome located in Zhukovsky, the flight test programme with the Saberlets-equipped SSJ100 was successfully completed. Manufacturer serial numbers 95032 and 95157 flew several tests with the new horizontal wing tips. One of the aircraft had ice simulators on the leading edge.
Overall, Sukhoi performed 140 flights with the aircraft. The programme included the examinations of the take-off and landing performance, stability and manageability, flight control systems and light functionality. Additionally, there were tests for strength, high speed flights and critical angles during the flight. Also, the manufacturer tested CAT I, II, and IIIa landings and take-offs.
Minister for Industry and Trade of Russian Federation Denis Manturov commented: “Sukhoi Superjet 100 – is dynamically developing program. The installation of the Saberlets allows to simultaneously improve the take-off and landing performance. Moreover, fuel effectiveness will improve.
