Status Joint-Venture established[1]

The CRAIC CR929, formerly known as Comac C929, is a planned long-range 250-to-320-seat wide-body twinjet airliner to be developed by China-Russia Commercial Aircraft International Corporation (CRAIC), a joint-venture between Chinese Comac and Russian United Aircraft Corporation (UAC), to challenge the Airbus and Boeing duopoly.

Development

In June 2011, Comac was studying the 290 seats C929 and 390 seats C939 wide-body aircraft.[2] In June 2012, Russia and China were to set up a joint venture between UAC and Comac to develop after demand evaluation for at least seven years and $7-12 billion an Il-96 successor and produce several hundred aircraft, with Russia contributing its knowledge and China providing the resources.[3]

In May 2014, a memorandum on cooperation was reached and a feasibility study completed in autumn 2014. UAC estimates a 8,000 widebody worldwide demand through 2033, with 1,000 in China. In November 2014 UAC said it would have a 12,000 km (6,500 nmi) range while Comac pointed a gap for a 7,400 km (4,000 nm) moderate range ; seating was targeted for 250-280 seats with later shrink and stretch. In February 2015 preliminary design had begun. In 2016 should be launched with detailed design a nine-year, $13 billion development program, targeting a 2025 introduction. Comac was likely to develop and build the fuselage while UAC handles the composite wing and fin.[4]

In June 2015, an agreement targeted a mid-2021 first flight, certification and initial deliveries in 2024. The airframe would be 50% composite and 15% titanium, UAC would deliver in 2019-2020 the first 360 ft (110 m) wide composite wing.[5] In November 2015 was announced the more fuel-efficient, re-engined Ilyushin IL-96-400M as a more attainable and affordable alternative.[6]

In June 2016 was signed an agreement to set up a 50-50 joint venture.[7] In November 2016 at Zhuhai Airshow Comac and UAC searched suppliers and approached Honeywell and United Technologies.[8] Its mock-up was exhibited there.[9] Comac and UAC estimated the development at 10 years, implying a first delivery in 2027 if the joint company is established and the program is launched in 2017.[10]

CRAIC joint venture

The China-Russia Commercial Aircraft International Corporation Limited (CRAIC) 50-50 joint venture was launched on May 22, 2017 in Shanghai, targeting a 2025-2028 maiden flight and first delivery. It aims to take 10% of a market dominated by Boeing and Airbus of 9,100 widebodies over 20 years through 2035, with a plane 10-15% cheaper to run.[1] Based in Shanghai where the assembly line will be located, CRAIC will oversee the programme : technology development, manufacturing, marketing, sales, customer services, and programme management. The fuselage will be aluminium, total investment will be $13-20 billion.[11]

Seating : 1-2-1 in First, 2-2-2 in Business and 3-3-3 in Economy

For 2023–45, UAC and Comac forecast a 7,000 widebodies demand for $1.5 trillion - an average of $214 million, their goal for first delivery is 2027. The 280 passengers capacity over 12,000 km is comparable to the Airbus A330-900 but with a nine-abreast economy seating, the shrink would seat 230 while the stretch 320. Major suppliers will be picked among 169 companies by the end of 2018, as detailed design should be completed and a joint engineering center in Moscow with a branch in Shanghai will oversee development, employing around 100 engineers from both countries. Comac's will be in charge of the fuselage sections, horizontal and vertical stabilizers, wing fairings, nose cone and landing gear; UAC will develop the composite wing, wing flap systems, engine pylons and main landing gear, with Chinese manufacture if it is cheaper.[12]

For Russia, Moscow will provide the know-how and technology, while Beijing will be responsible for the cash.[13] China could see the joint venture involving joint financial investments, rather than an intellectual property sale, as Russia wants with the research and development center in Moscow and the aircraft manufacturing in Shanghai.[14]

It will be named CR 929 (CR stands for China-Russia) and will come in three variants: the -500 will carry 250 passengers in three-classes with a range of 14,000 km (7,560 nmi), the -600 will have 280 seats and a range of 12,000 km (6,480 nmi) and the -700 will carry 320 over 10,000 km (5,400 nmi). Concept approval is slated for 2017, early configuration and preliminary design for 2018, design documentation for 2021, first flight for 2023 and introduction for 2025. It will be powered by a western engine at first before an indigenous power plant is developed between Russia's United Engine Corporation and China's AECC, to start testing in 2022 and be certificated in 2027.[15]

Engines

A competitive widebody would initially need Western powerplants and onboard systems.[4] It would need a 77,000–88,000 lbf (340–390 kN) thrust turbofan.[5] At November 2014 Zhuhai Airshow, a later high-thrust joint turbofan was discussed between Avic Commercial Aircraft Engines and United Engine Corporation (UEC), with parameters defined in early 2015 for an introduction between 2025 and 2030.[4] In September 2017, a memorandum of understanding was signed between Rostec's UEC and Aero Engine Corporation of China: initially joint research and customer requirements analysis and definition, then determining engine design and operating parameters before testing in 2022 and certification in 2027.[16]

A more powerful version of the Aviadvigatel PD-14 developed for the Irkut MC-21 could be developed after its certification in 2017, with a 50% scaled up core.[5] In August 2015 was also proposed a derivative of the Kuznetsov NK-32 powering the Tupolev Tu-160 supersonic bomber.[17] In May 2016 began the development of a 35 tf (77,000 lbf) Russian engine Aviadvigatel PD-35 for the twinjet, expected to enter service in 2025.[18] On the other hand, China have been working independently on the CJ-2000 engine which is also intended to be used on the aircraft.[19][20] [better source needed]
