Today, the third Sukhoi Superjet 100 flight prototype SN 95004 took to the air from Komsomolsk adding momentum to the flight test campaign. Prior to this, the flight test campaign included the first two flying prototype aircraft — SSJ100 # 95001 and # 95003.
This first Flight of SN 95004 began at 07:44 p.m. local time and lasted 1 hour and 21 minutes (landing local time -09:05 p.m.). The purpose of the flight was to check all aircraft system operations and to confirm their ability to ensure the safety o f the aircraft. The first flight of SSJ100 SN 95004 was quite similar to the flights performed to check the ramp-up production aircraft prior to delivery.
As Sukhoi Superjet 100 SN 95004 will undergo testing of the passenger cabin and avionics, it will be the first aircraft to be completely fitted with passenger equipment and the certification-ready avionics suite, which includes all options designed to meet the airlines' requirements.
Sukhoi Superjet 100 #95004 will demonstrate the full capabilities of the "dark-and-quiet" cockpit, which is powered by the avionics suite and designed to make the flight comfortable for the pilots and, therefore, safer for the passengers. Later, the aircraft will undergo a series of tests in Italy that will include checks on the community noise level, Instrumented Landing System, Precision Navigation (P-RNAV) and High Intensity Radiated Field (HIRF) tests.
Sukhoi Civil Aircraft Company test-pilots Nikolai Pushenko, who captained the flight, and Sergey Korostiev were the crew for SN95004's initial test flight. Pushenko and Korostiev also flew SSJ100 SN 95003 from Komsomolsk to Moscow via Novosibirsk this spring. "It is a pleasure to be the first to touch the controls of another SSJ100 and we are very pleased that, in accordance with the schedule of the flight test campaign, every "first flight" becomes more and more saturated as the operational functionality of the aircraft broadens", — said Nikolay Pushenko, after leaving the plane.
Upon completion of a few factory test flights and painting, the aircraft will follow the same route through Novosibirsk to SCAC's flight test center in the Moscow region and join the other two prototypes for their certification flights.
"Putting another Sukhoi Superjet 100 in the sky is an important milestone for us, as it demonstrates the capacity of this comfort oriented design, which has taken into consideration the noise and emissions of the aircraft, safety of the passenger cabin, and also the comfort of its pilots, crew, and passengers. It will supplement the daily flight display of SSJ100 # 95003 at MAKS airshow this August in the Moscow Region, showcasing the passenger cabin comfort at the static display", — noted Vladimir Prisyazhnyuk, SCAC's President upon completion of the flight.
Today, this aircraft joins the other two prototypes which together have accumulated more than 700 flight hours in over 270 flights. The tests performed thus far in the Moscow region have included flutter, natural icing, a significant part of high angles of attack, as well as other tests. The initial two prototypes began flight performance tests after SSJ100 SN 95003 returned from its international debut at the Paris Airshow, and included take off and landing tests, and also included tests of the stability and controllability of the aircraft. While flight performance covers a vast number of flights, a number of specific take off and landing missions — such as minimal unstuck speed, minimal control and control ground speed, as well as partial climb rate tests — had already been performed before the show. SSJ100 SN 95003 is currently undergoing engine performance trials. Both aircraft SSJ100 SN 95001 and SN 95003 have now performed the low speed section of stability and controllability tests.
