Sukhoi Superjet 100
Since the year 2012 the interior installation and systems final adjustment of RRJ-95 family aircraft began at «Aviastar-SP». Certified name of the airliner is Sukhoi Superjet 100 (SSJ). It is a new short-range passenger aircraft.
Development: Sukhoi Company (JSC)
First flight: 19 May 2008
Aircraft design complies with the requirements specification of Russian, CIS and western countries airlines and complies with the АP-25, FAR-26 and JAR-25 requirements. Aircraft family Superjet 100 meets the noise level requirements (noise made by the aircraft according to part 4 ICAO and FAR 36 standard Chapter 4, that came into force in 2006). Aircraft SSJ meet the requirements of 99% Russian and CIS class А, Б and В aerodromes.
On the third of February 2011 Intergovernmental Aviation committee issued the Certificate of the Aviation Register МАК type for the aircraft Sukhoi Superjet 100.
Aircraft certification according to the requirements EASA is planning to be finished in 2011.
The project of Russian regional aircraft family Sukhoi Superjet 100 is accomplished by JSC «Civil aircraft Sukhoi (ГСС)», established in 2000.
Nowadays 5 aircraft of this family are being in operation.
JSC «Aviastar-SP» accomplishes galley and toilet modules installation, side and ceiling panels, wardrobes, partitions, passenger seats and steward seats installation in complete set according to customer requirements. Emergency equipment, fire protection aids are installed on SSJ. Lights, galley equipment and oxygen equipment final adjustment are being installed on SSJ. Final stage is aircraft weighing and aircraft balance calculation after interior installation.
Cabin layoutOptimum fuselage section size allows passenger aisle increase to 510 mm (20.08») even at the layout of 5 seats in a row. Seats width is 465 mm (18.31»). There is more space over the passenger head in Superjet 100. Ceiling height is 2120 mm (85.04 ).
The conception «double-bubble», applied in fuselage section, allows space increase for one passenger up to 0.885 m3, and in baggage-in-cargo compartment height up to 1014 mm. At the configuration of 4 seats in a row aircraft Superjet offer full business-class with the equal comfort level for all passengers, seating both at the right side and at the left side. For greater comfort for passengers, there is a simpler and a more convenient access to shelves, that can easily keep suitcases with wheels, approved by IATA standards as hand luggage.
Design peculiaritiesFamily Sukhoi Superjet 100 aircraft (for 75 and 95 seats) have high degree of unification (to 95%): along the glider, wing, power plant, cockpit and main aircraft systems. Aircraft seat capacity increase is achieved by means of passenger cabin lengthening using additional devices installed into the cylindrical fuselage part. All aircraft Superjet 100 at this use uniformed geometry wing and minimum fuel system changes increase the aircraft range. During the operation of several Superjet 100 type sizes in a single fleet airlines get the opportunity to vary aircraft dimension depending on flight loading. Besides, high unification allows a great decrease in expenses on maintenance and repair.
Superjet 100 aircraft family is unique on new technologies, applied both in the aircraft itself and at all stages of its creation: starting with design and to its assembly.
The chosen high-lift devices scheme and overcritical wing section of the third generation and proper local aerodynamic final adjustment allow fuel economy. Optimum aerodynamic assembling is formed using up-to-date aerodynamic designing technologies and experimental investigations in aerodynamic tubing. High aircraft family fuel effectiveness is determined also by the presence of up-to-date engine, created on the basis of the last technologies CFM56 & Tech56 and possessing high performance. Engines SaM146 are developed by the company Powerjet taking into account all the requirements of the Superjet family 100. Great attention was paid to engine maintainability, for example, the opportunity of changing blades without engine removing from the engine. In the module design of the new engine the number of components is reduced to 20%, that provided costs reducing and maintenance procedure simplification. Due to up-to-date technologies used as the basis of the engine SaM146, all aircraft of the family overcome all effective and the nearest prospective ICAO requirements on the noise and emission level.
Aircraft fuel effectiveness is also increased due to optimum aircraft pilotage in the automatic mode, aircraft weigh economy and engine SaM146 performance.
Due to the automatic pilotage mode not only additional profit in fuel effectiveness is reached, but also high flight safety, because in this mode remote flight control system is protected from accidental faults. Remote control fail-safe system architecture allows full rejection of mechanic reservation. Horizontal stabilizer shift is also accomplished distantly. It helped to optimize its dimensions for its high control rate. It is the first time when algorithmic protection from touchdown at tearing off is applied on Superjet 100, that excludes the necessity of mechanic shock-absorbers usage, that other aircraft are equipped with.
The basis of ДСУП are three upper level calculators (PFCU- Primary Flight Computer Unit) and additional lower level calculators (ACE- Actuator Control Electronics). PFCU can process commands, coming from the cockpit on ACE, and optimize aircraft pilotage performance at all flight modes. At the same time, there is no need in switching to direct control in case of failure, and pilotage performance remain at the adequate control level.
Superjet 100 high operation manufacturability and weighing perfection is also reached by means of gear retraction/extension and brake system electrical remote control system realization.
Open avionics architecture is designed by the company THALES on the basis of integrated module technology. This allows approximately 15% enclosure boxes number reducing and therefore its maintenance simplification. For aircraft maintenance simplification airborne TM system is provided in total, that can detect failure in all basic aircraft systems. Basic avionics configuration at this is more functional in comparison with the nearest competitors: it includes triple USW-connection with the function ACARS, traffic collision avoidance system T2CAS of the second generation, the possibility of approach according to IIIA ICAO.
Due to the improved cabin lighting system, based on LCD-technologies, aircraft Superjet 100 gives his passengers additional comfort, and to airlines- additional economy due to more effective maintenance. Cockpit design includes the most prospective decisions of modern aviation: «passive» side handle, «active» engines control levers. The conception «Human Centered Design» allows control levers and instrumental equipment installation optimization. Thus, even in case of extraordinary situation it is possible to complete the flight by one pilot. These decisions in combination with the conceptions «Dark and Silent Cockpit» provide the possibility of aircraft Superjet 100 precise and reliable pilotage.
