Sukhoi Superjet 100 Cleared For Noise Flight Testing Certification

By Daniel Baxter

September 26, 2010 - On completion of 5 validation flights Sukhoi Superjet 100 has been cleared by ARIAC and EASA for noise program certification flights. At the Levaldigi airport SSJ100 is performing certification flights. The Sukhoi Superjet 100 is a modern, fly-by-wire regional jet in the 75- to 95-seat category. The Superjet 100 is produced by Russian aerospace firm Sukhoi's.

The jet is being developed in collaboration with Finmeccanica subsidiary Alenia Aeronautica. Thanks to telemetry equipment interfacing with on-board Aircraft testing instrumentation, the noise relevant flight parameters, including the aircraft trajectory, will be shown in real-time to flight test specialists sitting in Alenia Aeronautica Control Room located in Torino Caselle airport.


Subsequent to the flight, the data will be analyzed in the same Alenia laboratories to provide quick look assessment of aircraft noise characteristics. Since meteo data are essential for Noise tests, both on-ground and in-flight measurements will be taken during tests, the last by using a helicopter equipped by a special probe.

Prior to the clearance AR IAC and EASA verified the aircraft 95004 configuration, reference trajectories for noise certification, flight test procedures, flight and ground test instrumentation and calibration status. In course of AR IAC-EASA parallel certification, EASA experts have already taken part in high angles of attack program, airstairs ejection and hydraulic system pressurization checks.

?SSJ100 Noise and HIRF testing, conducted in Italy is not just a program which tests certain aircraft parameters, it?s an essential part of a big effort of AR IAC and EASA in harmonization of the certification standards of Russia, CIS and Europe. And this job is made possible owing to Sukhoi Superjet 100 Program, as SSJ100 is the pioneering aircraft which is designated for the both Russian and world market and has to meet the international certification norms?, said Igor Vinogradov, SCAC?s SVP on Certification.

SSJ100 is easy and safe to pilot. The cockpit design features a ?passive? side stick and ?active? engine control levers. The Human Centered Design concept perfectly arranges the control levers and on-board equipment. SSJ100 can be landed by one pilot only. Dark and Quiet Cockpit offers precise, convenient and reliable piloting of Sukhoi Superjet 100.


Sukhoi Superjet 100 is equipped with the built-in failure detection system able to find any failure including those at the LRU level of any major aircraft system. Moreover, the basic configuration of avionics offers wider functionality, including triple ultra-short-wave communication system with ACARS function, the second generation T2CAS system designed to prevent collision as well as the IIIA ICAO category approach capabilities.

Each aircraft is powered by the new SaM146 engine developed by PowerJet to meet the highest performance and eco requirements. Snecma Moteurs and NPO Saturns distinct experience and perfect synergy produced a hi-tech result by applying the CFM56 & Tech56 technologies when creating an engine distinguished for its excellent performance.

A strong focus was put on engine maintainability. Now the blades can be replaced with engine on the wing. Owing to the new modular design, the engine employs 20% less parts, which significantly streamlines maintenance operations. The double-bubble fuselage expanded ?life space? for each passenger up to 0.885 m3 and increased the height of the cargo compartment up to 1014 mm.

Sukhoi Superjet 100 ? a new family of regional jets ? is the Company?s major project. The aircraft was rolled out on September 26, 2007 in Komsomolsk-on-Amur. On May 19, 2008, the first Sukhoi Superjet 100 performed its maiden flight there. On October 24, 2008, after successful completion of factory flight tests, the aircraft emerged into certification flight campaign. Sukhoi Civil Aircraft was founded in 2000 to develop new regional aircraft projects. Headquartered in Moscow, the Company enjoys several production branches seated in the cities of Komsomolsk-on-Amur, Novosibirsk and Voronezh. Today the company employs over 2,000 people. 

The Italian design group Pininfarina will design optional interiors, and in 2007 Alenia Aeronautica and Sukhoi Holding formed SuperJet International, a joint venture (51% Alenia Aeronautica, and 49% ? Sukhoi Holding) based in Venice, responsible for marketing, sales and aircraft delivery in Europe, North and South America, Africa, Japan and Oceania as well as for worldwide logistic support for the Superjet 100.
