Sukhoi Superjets arrive at Russian Flight Test Centre in Zhukovsky
The first two Sukhoi Superjet 100 series aircraft have been delivered to the M.M. Gromov Flight Research Centre in Zhukovsky for flight certification testing.
The two aircraft, Sukhoi Superjet 95001 and 95003 were flown from Komsomolsk to Zhukovsky via the Siberian city of Novosibirsk. Both aeroplanes will continue the certification flight test campaign at the SCAC flight test centre, which is furnished with a full set of test
equipment and software packages required for flight data processing.
Conducting the certification test programme at the flight centres is expected to accelerate the certification test programme due to better logistics of data processing and interaction with certification authorities.
"The schedule of the SSJ100 certification tests is truly tough," said Igor Vinogradov, First VP on programme coordination, Sukhoi Civil Aircraft. "Within a limited time frame two test aircraft have completed more than 130 flights totaling more than 400 hours in the air."
To date, flutter safety tests as well as the first stage of the tests on high angles of attack and stall control have been completed. Both aircraft demonstrated the flutter margin within a whole range of operating altitudes and speeds. The flight control system was checked at direct and normal modes of the remote control system.
"The stability and control testing show good results. The overall test programme, including static tests at the Central Aerohydrodynamics Institute (TsAGI), eliminated the redesign risks," said Viktor Soubbotin, president of Sukhoi Civil Aircraft, summing up the results of the tests in Komsomolsk. "Expansion of the SSJ100 operating limits will make further tests within all approved ranges of heights and speeds possible."
