Sukhoi Superjet 100 (SN 95004) has successfully completed the type’s HIRF testing programme during flights from Turin-Caselle airport at the Alenia Aeronautica facilities.
The preliminary results show that the aircraft meets all certification requirements regarding HIRF (high intensity radiated field) tests.
The SSJ100 is the first Russian aircraft to accomplish the full scope of a HIRF certification testing programme. Its methodology was designed by the Sukhoi Civil Aircraft Company (SCAC) engineering team in collaboration with Alenia Aeronautica, with further approval of the Interstate Aviation Committee Aviation Register (AR IAC) and European Aviation Safety Agency (EASA).
HIRF certification is required to demonstrate that the aircraft’s electric and electronic equipment is not influenced by external electromagnetic fields like those produced by a TV or radio station or by a radar. Methods used in conducting the tests includes low level swept current, low level swept frequency, bulk current injection and high intensity radiated field.
“Completion of HIRF tests is an important milestone of the Sukhoi Superjet 100 certification programme. Our airliner is the first Russian aircraft that has compliance with international standards in this domain,” commented Igor Vinogradov, SCAC’s SVP for certification. “Recently during flight tests under the supervision of Russian and European certification authorities, the SSJ100 has successfully passed noise testing programme. This joint effort will definitely contribute to the harmonisation of the certification standards of Russia and Europe, as well as the successful entrance of our product into the international market.”
