Sukhoi Superjet 100 passes noise testing program

Oct. 14, 2010
TURIN, Italy, 14 Oct. 2010. The Sukhoi SSJ 100 from Sukhoi Civil Aircraft Co. in Moscow has passed a noise testing program performed as a part of its overall flight certification campaign with the European Aviation Safety Agency (EASA) and Interstate Aviation Committee (IAC) Aviation Register (AR) in Russia. At the Cuneo-Levaldigi airport in Turin, Italy the aircraft made eight certification flights. The preliminary results show that the aircraft noise levels show full compliance with International Civil Aviation Organization (ICAO) CAEPIV requirements.

The Sukhoi SSJ 100 from Sukhoi Civil Aircraft Co. in Moscow has passed a noise testing program performed as a part of its overall flight certification campaign with the European Aviation Safety Agency (EASA) and Interstate Aviation Committee (IAC) Aviation Register (AR). At the Cuneo-Levaldigi airport in Turin, Italy the aircraft made eight certification flights. The preliminary results show that the aircraft noise levels show full compliance with International Civil Aviation Organization (ICAO) CAEPIV requirements. The same aircraft -- #95004 -- is undergoing high intensity radio frequency (HIRF) testing, in the same premises. HIRF testing methodology was elaborated by the SCAC engineering team in collaboration with Alenia Aeronautica and relevant certification authorities. HIRF certification is required to demonstrate that the aircraft electric and electronic equipment are not influenced by external electromagnetic fields such as those produced by a TV, radio stations, or 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 avionics equipment monitored to check for any malfunction. Telemetry is used to monitor aircraft parameters in real time as well as to avoid radiation exposure during testing. "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," says Igor Vinogradov, senior vice president of certification for Sukhoi.
