Control points. Chinese-Russian CR929 aircraft going to the sky
Entertaining numerology
The wide-body CR929 should be considered Sino-Russian: the letter C is responsible for China, and R is for Russia. The joint venture for the development and assembly of winged vehicles is called CRAIC, China-Russia Commercial Aircraft International Corporation Limited. The 929 number also has some sacred meaning for the Chinese public - the 9 number stands for eternity, and the 929 index serves as a logical continuation of the name of the narrow-body COMNX919. But for Russian users there is a continuity, albeit not so obvious. Look, the MC-21, which has not yet reached the operational level, has 200 / 300 / 400 modifications in the project, and CR929 variants will be with additional 500 / 600 / 700 indexes. Elegant, isn't it? In fairness, it should be said that the aircraft is developed primarily for the market of Southeast Asia. CRAIC's head office is also located in China - it was opened in Shanghai on 22 on May 2017 of the year.
According to the plan of work on the new machine, they are geographically divided: in Russia, a center wing and wing consoles with mechanization are being developed, and in the PRC (more precisely, at COMAC), the fuselage and plumage. At the same time, the Russian side very much hopes that work on integrating the machine into a single whole will nevertheless go on in our country. Also in Russia, engineers will be fully responsible for all the avionics and logic of the control systems. The developments in vacuum infusion methods that we received with the “black wing” of MS-21 will also find their place in CR929. How much is story with a wide-body aircraft? As the head of the KLA, Yuri Slyusar, notes, in general, it is planned to spend no more than 20 billion dollars, naturally, sharing costs between the 50 / 50 countries. However, if you recall the constantly growing spending on SSJ-100 and MS-21 projects, you can hardly believe it. In September of 2018, the Minister of Industry and Trade Denis Manturov spoke at the peak of Slyusar when he announced the total value of 40 billion rubles.
Partner countries, according to the minister, will invest 20 billion in just three years. In general, you will not envy the integrators of the aircraft project: the car has two main designers, and the design bureaus are located almost on different ends of the continent. Only in Moscow are plans to gather more than 800 specialists of various profiles, both from the Russian and Chinese sides, under one roof of Sukhoi Civil Aircraft and the UAC. The developers plan in Russia to attract Aerocomposite JSC for the assembly of the wing, Irkut, and specialists in wide fuselages from Ilyushin. In this sense, the Chinese are easier, they are not so at risk of running into foreign sanctions and therefore attract foreign "helpers". So, with the Italian Leonardo 26 on October 2018, a joint venture Kangde Marco Polo Aerostructures Jiangsu was laid in Zhangjiang.
They will be engaged in the development and production of composite sections of the fuselage. And already on 26 of December of the same year, an experimental composite fuselage part with a length of 15 and a diameter of 6 meters was ready for Chinese partners. By the way, according to preliminary plans, the proportion of composites in the aircraft structure may exceed the record 50% (for SSJ100 - 10%, MS-21 - about 30%). CR929 has not actually left the stage of preliminary design, and China is already fantasizing about its military version. In particular, there are thoughts about building a strategic tanker and AWACS aircraft.
Step by step
At the moment, the most interesting controversial moment in the history of CR929 is the choice of a site for the production of a huge composite wing. The problem is that it is not included in the An-124 cockpit, no one will give money for the development of a specialized aircraft for transportation (and never pay for it like that), but somehow it is necessary to deliver the assembly to the stocks in Shanghai. The possibility of disassembling parts from Ulyanovsk is being considered, but this entails difficulties with the design and makes it heavier. Trying to get the wing on water is ridiculous - just look at the globe for that. One thing remains: to build new production near China, presumably near the port of Vladivostok. And these are separate and considerable investments. Where will they be found and then what will Russia do immediately with two factories specializing in composite production?
At the moment, the CR929 development process, according to officials, is going according to plan. In the near future will be passed the control point Gate 3. That is, a preliminary study ends and are determined with the main suppliers of on-board systems. At the previous Gate 2 point, which the developers successfully passed at the very end of the 2017 of the year, defended the technical concept or philosophy of the future machine. And here the issue with engines remains unresolved. They are considering ready-made options from GE (GEnx-1B76) and Rolls-Rolls (Trent 7000 or 1000E), which even though now install under the wings, but Russian and Chinese engineers want, of course, their product. An alternative for the distant future will be the promising PD-35 with a thrust of about 35 tons, but it will have to wait about 8-10 years. Therefore, you have to choose between American and British proposals. In addition to choosing a power plant, engineers by the end of this year to complete the Gate 3 need to have time to work out the nuances of aerodynamics, choose materials for the design and carefully work with future customers.
It is assumed that the main customers will be "their" companies Air China, China Eastern and China Southera - in this sector CR929 plans to squeeze the duopoly of Boeing and Airbus. In total, China will be able to buy about 1200 aircraft in twenty years, while in Russia, a maximum of orders for 120 aircraft will be gathered in the same time. And this is at best. The first supply contracts and letters of intent at CRAIC are already awaiting the technical design phase. That's exactly when the project is waiting for the most serious multibillion expenditures, the first delays in the stages of development and the first unforeseen expenses. Actually, everything that we saw and observe with the SSJ100 and MS-21 projects. According to the most cautious opinions, we will see the first prototypes of the car in the sky in the 2023-2025 years. At the moment, the developer is not going to move away from the key concept of CR929.
This long-range wide-body aircraft is supposed to be built in three versions of the basic version of the CR929-600 on the 281 passenger in the three-class version, on the 291 person in the two-class layout and on the 405 in the single-class version. There is also an “extreme” version for 440 people, which will be placed in seats with a sealed arrangement. Apparently, a fragment of just such a cabin caused a grin from Erdogan at the MAKS-2019 air show. The Russian president then showed the Turkish leader a full-size model of the compartment of the aircraft 22 meters long, 5,9 meters wide and 6,5 meters high, which was brought specifically for the Moscow air show from China. The real CR929 will be a large machine - take-off weight in all versions will be equal to 245 tons, wingspan - 63,9 meters, the length of the “six hundred” version will reach 63,8 meters, and the height will be 17,4 meters. The flight range, depending on the modification (short 500, medium 600 and long 700) will vary from 10000 to 14000 kilometers.
No matter how corny it sounds, CR929 will have to be tight in terms of conquering the market. Of course, in both Russia and China it will be possible to turn on the administrative resource and force companies to turn their eyes to the new product, but in other markets Boeing and Airbus will remain unshakable. New-fashioned chips such as an ultralight composite case and unique fuel efficiency will not help here. It is necessary to create a global fleet service system and build a reputation. And this, unfortunately, is not included in the financial plan of the CR929 project.
