On December 21, 2017, Sukhoi Superjet 100 performed its first flight with the installed saberlets in Zhukovsky. The saber-like configuration of the tips installed on to the Sukhoi Superjet 100 turned out to be the result of a number of research, engineering and experimental activities carried out by the Sukhoi Civil Aircraft Company with the assistance of The Central Aerohydrodynamic Institute (TsAGI).
The geometry of the tips was determined with the implementation of the innovative methods of 3D optimization based on numerical computation called Computational Fluid Dynamics (CFD) – the unique TsAGI know-how used in Russian aviation industry in particular for Sukhoi Superjet 100 program.
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, the materials used are certified in Russia as well as abroad.
