On the 21 December 2017 Sukhoi Superjet 100 performed its first flight with the installed saberlets in Zhukovsky.

The flight of the SSJ100 tail number 95032 with the installed saber-like tips took 2 hours 42 minutes. According to the flight plan the SCAC crew performed the appraisal of the aircaft stability and manageability under different flap configurations. Different modes were also performed in order to determine the level of fuel consumption at different flight stages. The flight was carried out up to 11 000 meters.

The saber-like configuration is a result of research carried out by the Sukhoi Civil Aircraft Company with the assistance of Central Aerohydrodynamic Institute (TsAGI). The results of research and experiments showed that the installation of the saber-like tips allows to simultaneously improve the take-off and landing performance and decrease the fuel consumption for not less than 3%. The expected improvement of the take-off and landing characteristics will be obvious for the carriers operating the aircraft at regional runways and in hot weather conditions as well as on mountain aerodromes (Hot&High).

The end of a full-scale program of ground and flight tests will result in the certification of the SSJ100 with the horizontal tips – saberlets and they will be offered as an option to the customers. The installation of the tips is possible not only to new aircraft but to the already delivered aircraft as well. VASO (Voronezh aircraft manufacturer) is the manufacturer of the saberlets kits.
