Sukhoi Completes Pressure Test

On June 22 upon completion of the scheduled test of the fuselage at a pressure equal to 125 percent of operational load and tuning the tensometric sensors, Sukhoi Superjet 100 resumed factory flight tests. The completed tests allow for longer flights at the higher altitudes. Tests continued with two more Sukhoi Superjet 100 on June 22 and 23, during which pilots – Alexander Yablontsev and Leonind Chikunov – continued to evaluate in-flight performance, stability and controllability at cruise, take-off and landing positions of control surfaces with landing gear extracted and retracted at the altitude of 1000 and 3000 meters. In order to evaluate stability and controllability the pilots executed maneuver of shifting from turn with 30° bank angle to the turn in the other direction with same bank angle.
The first four flights produced the initial evaluation for fuel consumption which demonstrates good compliance with expected characteristics. The pilots as well as flight results on the controllability and stability tests confirmed flight dynamics set during simulation results at TsAGI and SCAC.
