Sukhoi Superjet 100 has successfully passed noise testing program

October 12, Turin - Under supervision of AR IAC and EASA, the SSJ 100 has successfully passed noise testing program performed as a part of the overall certification campaign. At the Cuneo-Levaldigi airport the aircraft made 8 certification flights. The preliminary results show that the aircraft noise levels show full compliance with ICAO CAEPIV requirements.

Being now cleared by AR IAC and EASA, the same aircraft #95004 is undergoing HIRF testing, in the same premises. HIRF testing methodology was elaborated by the SCAC engineering team in collaboration with Alenia Aeronautica, a Finmeccanica Company, and relevant certification authorities.

HIRF certification is required to demonstrate that the aircraft electric and electronic equipments are not influenced by external electromagnetic fields like those produced by a TV or radio station or by a radar. HIRF testing technique consists in radiating the aircraft with radio waves whose frequencies and levels of emission are set by Certification rules. The aircraft can be electrically powered or unpowered, and engines can also run. The electromagnetic fields and currents on cables inside the aircraft are measured during radiation and avionic equipments are kept under control to check for any malfunction. Telemetry is used to monitor aircraft parameters in real time as well as to avoid people exposure to radiation during tests with powered aircraft.

“Sukhoi Superjet 100 is the first aircraft in Russia that has compliance with international noise standards proven in flight under supervision of Russian and European certification authorities. It’s a real milestone of the SSJ 100 Program which confirms good perspective for the aircraft worldwide sales”, - said Igor Vinogradov, SCAC’s SVP on Certification, commenting the finalization of the noise testing program
