The Irkut MC-21 (Russian: Иркут МС-21) is a Russian single-aisle twinjet airliner, developed by the Yakovlev Design Bureau and produced by its parent Irkut, a branch of the United Aircraft Corporation (UAC). The initial design started in 2006 and detailed design was ongoing in 2011. After delaying the scheduled introduction from 2012 to 2020, Irkut rolled out the first MC-21-300 on 8 June 2016 and first flew the aircraft on 28 May 2017. It has a carbon fiber reinforced polymer wing and is powered by Pratt & Whitney PW1000G or Aviadvigatel PD-14 turbofans. With a capacity of 132–163 passengers in two class, up to 165–211 and up to 6,000–6,400 km (3,200–3,500 nmi) range, the standard MC-21-300 will be followed by a shortened MC-21-200. By July 2018, it had received 175 firm orders and recorded nearly 150 intentions.

Naming

In Russian: МС‑21 "Магистральный Самолёт 21 века" – "Magistralny Samolyot 21 veka" translates as "mainline aircraft of the 21st century".[9] It was called MS-21 in English before June 2013, but its official name is MC-21.[7] The MS-21 is marketed in the West as the MC-21,[10] despite the aircraft's original Russian model name being МС-21, which transliterates as MS-21.

In 2013, Russian deputy premier Dmitry Rogozin indicated that it will be designated Yak-242 once it enters serial production, the name of a 1990s proposal of an aircraft of similar size.[11] In 2014, Oleg Demchenko, the president of Irkut at the time, also preferred the Yak-242 name, claiming it would better reflect the design bureau behind the aircraft, however he has also said that any of these renaming decisions would be after the aircraft first flight and certification work.[12]

Development

Assembly of prototype in January 2016

In 2006, the UAC design goal was to seat 130–170 passengers over 5,000–6,350 km (2,700–3,430 nmi) to replace aging Tu-154, 20–25% more efficiently than the Airbus A320 and B737NG competitors with 15% lower weight, 20% lower operating costs and 15% lower fuel consumption, it was due to enter service in 2012 for an initial target price of US$35 million, $20 million below the similar 737-700.[13] The program was launched in 2007, planning a 2016 introduction.[9] Those goals were reiterated in 2008, except for the general efficiency gain lowered to 10–15%.[14]

In 2009, the MC-21 was in the "pre-design" phase, with projected completion of the first prototype in 2013 and the first flight in 2014.[15] By June 2011, the "pre-design" phase was completed and the "working design" stage was under way with three-dimensional models and drawings for subcontractors and suppliers, to be completed by mid-2012.[16] In February 2012, Russian deputy prime minister Dmitry Rogozin announced it was slated to begin certification tests in 2015/2016 and to enter production in 2020.[17]

On 8 June 2016, the -300 was rolled-out in Irkutsk, East Siberia, six years after program launch and with 175 orders. It could be the first commercial aircraft with an out of autoclave composite manufacturing for its wings. The program faces domination of the single-aisle market by Airbus and Boeing and Russian protectionism hampering critical western suppliers for the avionics, landing gear, hydraulics, power systems and engines. Its introduction was delayed to the end of 2018.[18][19] It is intended to rival the Airbus A320neo or Boeing 737 MAX and will replace the outgoing Tu-134, Tu-154, Tu-204 and Yak-42.[20]

Ground Testing

In February 2017, it passed 90% of the static ultimate load test (150% of the highest load in operation) at the TsAGI but failed the 100% test for which the wingbox will need 25kg reinforcements: this is common for new airliners like the Airbus A380, Boeing 787 or Mitsubishi MRJ, aiming for the smallest possible margin to avoid excess weight; it passed the limit load test (highest load during flight) which enables flight testing which should start in April.[21] Cracks developed at the point of contact between the titanium beam and the composite wing skin in the wingbox.[9] The reinforced wingbox withstood a load exceeding specifications without damage in mid-November at TsAGI Moscow.[22]

In May 2017, it was undergoing systems ground testing including its auxiliary power unit and taxiing tests.[23] After completing taxi and runway roll tests, its maiden flight was scheduled for late May 2017 with Pratt & Whitney Geared Turbofan engines, certified in September 2016 in Russia. The Russian certification is targeted for 2018 and the European Aviation Safety Agency certificate for 2019.[9]

Flight Testing

On 28 May 2017 MC-21 made its successful maiden flight in Irkutsk.[2] Compared with recent 3-4 hour maiden flights of western types, this first flight was brief at 30-minute and low, reaching a 1,000 m altitude and 300 km/hour.[24] The maiden flight was originally scheduled for December 2016, then to April before finally taking place in May.[25]

Following this maiden flight, trade and industry minister Denis Manturov claims it will have 12–15% lower operating costs than contemporaries, generating a demand for over 1,000 MC-21s between 2017 and 2037.[26] Aeroflot expects delivery of the first aircraft through Rostec subsidiary Aviakapital leasing in 2019.[9] Its early production rate is projected for 20 aircraft per year.[27]

In August 2017, the first prototype performed nine test flights, analysing stability and controllability in various configurations, altitude, altitude/speed sensors accuracy and engine operation. Its software is adjusted by the results as it is fitted with over 500 strain gauges measuring in-flight loading on the airframe, to verify the initial design, for "several weeks". A second prototype is finalised while three other prototypes are undergoing construction; production of 70 MC-21s annually is planned for 2024.[28] Irkut began the second testing phase on 13 September with an eventless 2h flight.[29] The phase will extend the mass, centering, speed and altitude envelope.[30]

In October 2017, the first prototype flew from Irkutsk Aviation Plant to Moscow Ramenskoye Airport to continue testing at the Gromov Flight Research Institute, a 6 h flight over 4,500 km (2,400 nmi) at 10,000 m (33,000 ft), piloted by Oleg Kononenko.[31] The flight test programme started on 2 November with a 3h flight reaching 12,000 m (39,400ft).[32] Before being flown to Moscow, 20 flights were conducted in Irkutsk. In November, the second prototype was prepared for flight-tests, followed in 2018 by the third for which final assembly has started.[33]

EASA approval is targeted for mid-2020.[33] Certification testing was to start at the end of 2018 for a mid-2019 Russian type certification after a 1,150 flights effort. Entry into service was then planned for the second half of 2019 with the first five deliveries and within five years UAC plan to ramp up production to 70 aircraft per year.[34]

The second test aircraft was in final assembly in January 2018 and was to join the flight-test campaign in the first quarter.[34] It was to fly in late February or early March 2018.[35] Its construction was completed by March end.[36] It was scheduled to fly in April 2018, and the third in the 2018 fourth quarter.[3] It made its first flight on 12 May for 1h 7min, reaching 3,000 m (9,800 ft) and 215 kn (398 km/h), checking its landing gear retraction and testing wing configurations.[37] On 20 July 2018, it flew from Irkutsk to the Gromov Flight Research Institute near Moscow in six hours.[38]

Production is starting in 2018, certification slipped to late 2019 and the first delivery to 2020.[3] For three years from 2018, UAC plans to invest ₽56.4 billion ($899 million) for the MC-21.[39] By October 2018, two EASA test pilots and a test engineer had flew it towards European certification.[40]

Introduction

Aeroflot will lease 50 MC-21-300 from Aviakapital for 12 to 18 years and a monthly lease below $437,282 each, to be delivered from the first quarter of 2020 to the third quarter of 2026, with EASA certification from early 2021. Powered by PW1400Gs or maybe PD-14s for the second half, Irkut guaranteed a less than 9,865 kg (21,749 lb) fuel burn on a 3,240km (1,750nmi) route with a 14 kn tailwind. They will be guaranteed to reach 2,100h and a dispatch reliability of 96% for the first year, rising to 2,900h and 97% in the second year then 3,750h and 98.5% in the third year.[41]

In October 2018, fuselage panels for the first customer MC-21 were completed by United Aircraft subsidiary Aviastar.[42]

Design

The design is based on the never-realized, twin-engine Yakovlev Yak-242 as a development of the three-engine Yakovlev Yak-42.[11]

Airframe

In March 2008, Sukhoi was selected to design and produce the carbon fiber composite wings.[14] The UAC subsidiary AeroComposit developed the vacuum infusion to produce the wingbox and wing panels. The vertical and horizontal fins and wingbox are also composite and the high aspect ratio wing is a supercritical airfoil.[9] The MC-21 design is more innovative than the C919: it is the only airliner with a CFRP wingbox made with resin infused dry fibre, cured in an oven out of autoclave.[43] The initial design was including ~33% composite materials, increasing to 40–45% with the composite wing.

Its fuselage is 11 cm (4.3 in) wider than the A320/C919 and 27 cm (11 in) wider than the 737, for a 61 cm (24 in) aisle allowing passing others or a trolley.[43] Its 79.25 t (174,700 lb) MTOW is the same as the almost 5 m (16.5 ft.) shorter A320neo, and is 3 t (6,600 lb) lighter than the almost 3 m (9.8 ft) shorter 737-8, for similar two-class layouts of 162 to 165 while the 737-8 and A320neo have 200 nmi (370 km) more range.[34] The MC-21 is a low-wing cantilever monoplane with a composite structure, a tricycle landing gear, powered by two wing-mounted turbofan engines and with a 3.81 m (150 in) wide cabin.

Engines

The 30,000 lbf (130 kN) thrust class Pratt & Whitney PW1000G was selected in December 2009.[44] The Russian engine will be the 8–16 tf (18,000–35,000 lbf) Aviadvigatel PD-14.[45] Its certification is slated for 2018.[9] United Engine will deliver five PD-14s for the MC-21 by the end of 2018, after Rosaviatsia certification, to start flight tests in 2019 for type certification of the variant in 2021.[46]

Systems

In August 2009, Hamilton Sundstrand, a subsidiary of United Technologies, announced it will provide electric power generation and distribution equipment for $2.3 billion over 20 years of production.[47] Rockwell Collins and its Russian partner Avionika were selected to supply the MC-21's avionics.[48] Honeywell, Thales and Elbit Systems supplies avionics with 9 X 12 in multifunction displays, electronic flight bags, synthetic vision and enhanced vision systems The MC-21 will be the first airliner with active sidesticks, supplied by UTC Aerospace Systems.[9] It has Fly-By-Wire controls.[43] It has a glass cockpit with side-stick controls and an optional Head-up display.

Goodrich Corporation, also a subsidiary of United Technologies, along with Aviapribor was selected to provide the flight control system actuators.[49] Zodiac Aerospace, Eaton and Meggitt provide other components.[9] Interior furnishings will come from Zodiac Aerospace, coordinated from C&D Zodiac in Huntington Beach, California. Innovations from Zodiac Aerospace in Carson, California, will be incorporated in the water and waste systems.

There are two types of auxiliary power units (APU) designed with specifications suitable for MC-21: HGT750 from Honeywell Aerospace[50] and TA18-200 developed by Aerosila.[51]

Variants

In 2009, the MS-21-200 was designed around 150 passengers in single-class configuration, to be followed by a 181-seat -300 and 212-seat -400 with basic and extended-range models, plus a very-long-range MS-21-200LR[15]

MC-21-300
Standard model, 163 passengers in two class, up to 211, up to 6,000 km (3,200 nmi) range
MC-21-200
Shortened version with 132 passengers in two class, up to 165, up to 6,400 km (3,500 nmi) range

Proposed

Initially a 132-seats MC-21-100 variant was planned but then superseded by the Superjet 100 development.[52] The small variant with a capacity of 130- to 150-seat was proposed with commonality with the Sukhoi Superjet 130.[53]

UAC considers more developments for the MC-21 by 2035. These include: a -400 with 18 tf (40,000 lbf) engines for a 105 t (231,000 lb) MTOW, a -500, a -600 with 20–25 tf (44,000–55,000 lbf) engines, and a -700 with 30 tf (66,000 lbf) engines, as well as a MC-21X with a 155 t (342,000 lb) tons MTOW for a 9,000–10,000 km (4,900–5,400 nmi) km range.[54] Ilyushin Finance wants a MC-21-400 stretch for up to 256 seats and plans to buy 20 to 60 of them.[55] The 250-passenger MC-21-400 single-aisle twinjet could be jointly produced in the United Arab Emirates.[56]

Orders

By the end of the 2013 MAKS Air Show there were 175 firm orders including 50 for Rostec subsidiary Aviakapital leased to Aeroflot and 35 more with PD-14 engines for governmental customers, 50 for Ilyushin Finance (10 leased to Red Wings Airlines and six to Transaero), 30 for VEB Leasing (10 leased to UTair Aviation and 6 to Transaero) and 10 for IrAero with an agreement for 20 others leased from Sberbank of Russia, for a potential 195 orders.[57] Transaero bankrupted in 2015.

In June 2016, Azerbaijan Airlines has tentatively signed to lease ten -300s from Ilyushin Finance.[58] By July 2018, it had received 175 firm orders and recorded nearly 150 intentions.[59]
