Sukhoi SuperJet 100

Sukhoi SuperJet 100 (Sukhoi SuperJet 100, SSJ 100) is a short-haul airliner introduced by the Russian company Sukhoi Civil Aircraft in the 2000s.

History

By the beginning of the XXI century, most of the medium-haul and passenger air transportation in Russia was carried out on Tu-134, Tu-154, and Yak-42 aircraft. All these models were obsolete, and they could not compete with each other.

In 2000, the Sukhoi company, specializing in military aviation technologies, decided to create a passenger plane for short and medium lines. For this, a new company was created – Sukhoi Civil Aircraft (GSS).

The children’s city of the new firm was to become an aircraft, called the RRJ (Russian Regional Jet).

Designing and creating postings at a fast pace. Already in 2007, elements of the prototype were delivered by An-124 Ruslan aircraft from the Sukhoi plant in Komsomolsk-on-Amur in Zhukovsky for open testing. While the prototype is ready for testing, the second prototype took part in the official presentation (rolling out) at the factory for the assembly of developers and publications.

In 2008, the prototype RRJ made its first flight at the airport in the Moscow region Zhukovsky. The flight tests of the liners began. Already in 2009, the aircraft was first demonstrated at the air show in Le Bourget. A little later, another second side joined the flight tests, already fully equipped with all systems and a passenger cabin.

Even then, the first contracts for aircraft were concluded. It was planned that by 2010 the SSJ 100 will begin to enter the fleets of launch customers – Armenian Armavia and Russian Aeroflot. However, this plan could not be implemented due to difficulties with certification and delays in engine production. In 2010, three aircraft participated in flight tests.

In 2011, the SSJ 100 received a certificate of the IAC type (according to certification documents it is listed as RRJ). In the spring, the first plane was handed over to Armavia. In 2012, the aircraft received an EASA certificate. SSJ 100 became the first domestic aircraft certified according to EASA standards, which also makes it possible for the first time for any airline in the world to buy and operate these aircraft (many countries have their certification bodies, such as the FAA in the USA, but their requirements are close to EASA requirements )

Over the next few years, the GSS continued active flight tests to expand the capabilities of the aircraft and obtain permits (heat, highlands, automatic landing, steep glide path, and so on). Also, the SSJ 100LR version was certified – with an increased flight range.

Features

SSJ 100 – a classic modern airliner with a low wing low sweep wing and jet engines suspended under the wing.

According to the distribution of the shares of various materials, the aircraft is also classic, made mainly of aluminum alloys. Part of the mechanization of the wing, nose cone, and elements of the root part of the wing are made of composite materials.

The cockpit is glass, developed by GSS specialists, together with Sukhoi Design Bureau and Thales concern. The interface includes five multifunction displays. Control in flight is carried out using side sticks, instead of classic helms (similarly with the cabins of Airbus airliners).

The passenger cabin SSJ 100 is the most spacious in the class of regional jetliners. Due to the increase in the fuselage cross-sectional area, the cabin has a width of 3.24 meters (compared to 2.74 meters for the Embraer 190), which is closer to the performance of medium-haul aircraft (Boeing 737, Airbus A320).

Power plant – two SaM146 turbofan engines. The engines were created jointly by NPO Saturn and Snecma specifically for SSJ 100 liners.

Modifications

  • SSJ 100 (RRJ-95B – Asic) – the basic modification of the aircraft, certified in 2011.
  • SSJ 100LR – modification with increased take-off mass, boosted engines, and an increased range of 1,500 km. It was created in 2013.
  • SBJ – version for VIP, government, and corporate transportation. In the VIP version, it can carry 19 passengers at a distance of up to 7415 km.
  • SportJet (Sportjet by Sukhoi) is a special modification for the transport of athletes. It will be equipped with special equipment for recreation and comfortable transportation of athletes and staff.
  • SSJ SV (Stretch Version) – modification with an extended fuselage, which can accommodate up to 120 passengers. Commissioning is scheduled for 2020.

Operation

At the beginning of 2017, more than 90 SSJ 100 aircraft were operated in the fleets of airlines and public services of different countries. The largest operator is Aeroflot (30 aircraft), the second is the Mexican InterJet (22 aircraft).

Since its inception, the plane has had many problems, including difficulties with mechanization, defects in structural elements, failures in some auxiliary systems, and so on. However, none of them is critical to flight safety and most of them are “cured”. Reliability indicators of operation, although inferior to foreign counterparts, are growing and approaching standards.

One of the main problems of the SSJ program, as well as the civil aviation industry in Russia in general, especially in the international market, is the lack of an after-sales technical service network. When difficulties arise, aircraft are delayed, which negatively affects the economic benefits of their operation. However, with the increase in the number of operated liners and airlines, as well as with the introduction of other UAC aircraft (primarily MS-21), the service network will also develop.
