Fourth Sukhoi Superjet 100 flight test prototype arrives to Zhukovsky (Moscow Region)
Today the fourth Sukhoi Superjet 100 flight test prototype SN95005 flew from Komsomolsk-on-Amur to Zhukovsky-based Sukhoi Civil Aircraft Company Flight test center to continue flight certification campaign. Flight certification campaign tests scheduled for this aircraft include the evaluation of on-board equipment and, together with 95004, systems failure safety. SN95005 will accomplish tests on both fire protection and inertial gas systems. Sukhoi Superjet 100 is the first Russian aircraft to feature inertial gas systems. Its implementation is a must according to the American and European aviation authorities introduced to enhance flight operation safety. Inertial gas system fills the fuel tank with nitrogen deployed from the air in proportion to the fuel consumed. Its application allows preventing fire and detonation of fuel fumes in case of unfortunate critical landing.
