TsAGI holds strength tests of the Sukhoi Superjet 100 wing-flap system

press release


In the beginning of August specialists of the Zhukovsky Central AeroHydrodynamic Institute (TsAGI) conducted periodic testing of composite material parts of the Sukhoi Superjet 100 wing-flap system.

It was the proof-load test for the two flaps -internal and external- and the aileron. They first were loaded to the level of 40%, and then over 100% of the design load. The testing purpose was to verify the manufacturing technology of a new lot of units made of polymer composite materials.

“When the factory produces a run of 30 elements, one example is sent to TsAGI for periodic testing to confirm the quality of manufacturing technology,” explained Victor Tsygankov, the Head of TsAGI’s Static and Thermal Strength Department. “If the element does not withstand the load the whole lot is scrapped. In our case, all three units showed good results under specified loads and won TsAGI’s approval.”

The Sukhoi Superjet 100 (SSJ100) is a new-generation Russian civil aircraft designed and produced by Sukhoi Civil Aircraft Company (SCAC.) It is to operate on short- and medium-haul routes. TsAGI has been cooperating with the Sukhoi Civil Aircraft Company on the Sukhoi Superjet 100 project since 2001, having implemented during this time the full complex of research in aerodynamics, strength and the aircraft control systems. The SSJ100 has been in commercial service since 2011.

The SSJ100 composite wing mechanization units are produced at the Voronezh research plant PJSC “VASO.”
