Three minutes to talk about popular science
The CR929 wide-body passenger aircraft jointly researched and developed by China and Russia has become China's independently developed C929
Some people always feel that they have been split, and then look at the atmosphere of the first flight scene happily beating gongs and drums, and 10,000 moods are galloping in their hearts.
It is said that when I studied CR929, Da MaoExpect us to pay, and the technology never talks about sharing, the war distracted Da Mao's energy, and the breakup was also a last resort.
At the same time, it is inevitable that Da Mao wants to study his own wide-body aircraft, more than 90% of Da Mao's passenger planes were imported from the United States, and it is rare to make domestic products, and the key technology still depends on people's facesIt's better to control 100% of the heavy weapons of a big country!
Watching Da Mao take off, I must also want to know, what is our independent research and development?Is Da Mao's R&D so fast and reliable?Today, let's talk about the Chinese and Russian planes.
This incident began in 2011, when the rabbit was on the rise, and the rabbit's aerospace should develop, especially the rabbit's self-esteem is still so strong, and he must master the technology himself.
Therefore, after the successful production of C919 and ARJ21, the rabbit is ready to devote itself to the research and development of large wide-body passenger aircraft, and gradually replace the Boeing series of Eagle Sauce.
The ideal is very plump, the reality is very skinny, it is said that it is self-developed, but there is no benchmark for reference, how can it be played?
The rabbit thought about it, so he looked for Da Mao to cooperate in research and development, so COMAC found the Russian United Aviation Manufacturing Group and held a press conference to officially announce the joint design and development of the Sino-Russian wide-body passenger aircraft project.
The good times do not last long, when everyone thinks that China and Russia will give the world a miracle, in September this year, He Dongfeng, chairman of COMAC, said at a meeting that the domestic C929 is being designed and is expected to be fully launched in 2030. Such an important and sensitive information instantly **catches "domestic C929?".r flew?”For a while, the news was overwhelming, and the whole country was sighing that Da Mao broke up with us unconsciously.
The reason for this is that, on the one hand, Da Mao and Rabbit have different opinions on whether to use some foreign advanced technologies in the core components of CR929, on the other hand, Da Mao is busy fighting with Xiao Wu, and the research and development and production of military aircraft are imminent, and he has no intention of slowly studying with Rabbit.
In the end, because both sides hold 50% of the shares, it is too difficult to make decisions, and the little technical work left by Da Mao's ancestors is unwilling to be shared.
Of course, COMAC also made it clear that the C929, as a domestic wide-body passenger aircraft, is imperative to be developed and will not be shelved because of the withdrawal of Russian United Airlines, and China's wide-body passenger aircraft will meet the world in 2030.
Although this cooperation did not bring the relevant technical achievements we wanted, it also reminded us that the important weapon of the country, technology must rely on itself, in our own hands in order to gain a firm foothold.
After the rabbit left Da Mao, he devoted himself to the study of domestic aircraft, and did not dare to slack off for a moment, but he did not expect the speed of Da Mao to be amazing, and after breaking up for just two months, the child was suddenly born, and on November 1, Russia announced that the Il-96-400M long-range wide-body passenger aircraft made its first successful flight in Voronezh.
As soon as the news came out, especially the rabbit who had just broken up with Da Mao, someone insisted on linking the first flight of the Il-96-400M with the withdrawal from the research and development of CR929 in SeptemberIt is believed that Da Mao is suspected of leaving China alone to enjoy the fruits of victory
But take a closer lookIt is not difficult to find that the Il-96-400M is far from the standard of our C929 in terms of engine application and fuselage structure design, If you investigate further, you will know that this aircraft was improved by Da Mao on one of their old planes, which was supposed to be tested in 2021, but the epidemic has delayed, and it has nothing to do with withdrawing from CR929. And Da Mao's choice to test fly an aircraft that is not avant-garde but nationally produced at this time is also a significant move.
The prototype of the Il-96-400M is an upgraded version of the Russian Il-96-300, and the aircraft of the Il-96-300 series can be traced back to 1976, when Da Mao tested a "Il-86" is also a long-range passenger aircraft with 4 engines. Due to the short research and development time and the lack of a solid foundation, a series of problems arose after the Il-86 was put into operation, and some of them were barely produced before being discontinued.
Later, the upgraded Il-96 even as Putin's special plane has been embarrassingly grounded, small problems continue, with the change of the international situation, Da Mao also began to buy the Boeing series of Eagle sauce, don't say, it is really easy to use, so Da Mao has not cared about the development of Il-series aircraft over the years.
Including today's Il-96-400M, it is still inevitable that there will be some technical problemsFor example, it continues the four engine units of the Il-seriesThere is a gap with the international advanced twin-engine technology, because the thrust of the engine of Da Mao is only half of the thrust of the engine in Western countries
Looking at it this way, the Il-96-400M is a domestic technology that Da Mao picked up again in response to the current international situation. Since the outbreak of the war between Da Mao and Xiao Ukraine, Da Mao's family has so many Boeing planes, and now they can't even buy maintenance parts.
Although from the early development, the Il-series R & D design is not perfect, and the technology is not the world's advanced, but it is better than the national production!At this time, the first flight of the Il-96-400M is an important step for Russia's breakthrough, a symbol of national confidence in the world, and a great stride to promote the development of Russia's domestic civil aviation industry, which is of great significance.
Da Mao's withdrawal from C929 is not necessarily a bad thing for rabbits, whether it is an opponent or an ally, we can't always expect to find a shortcut to growth in others, especially the core technology of heavy weapons, and it is necessary to independently develop intellectual property rights.
At the end of November, Qi Xuefeng, deputy general manager of COMAC, talked about C929, which is China's dream wings, the wide-body passenger aircraft has entered the detailed design stage, after successful research and development, China will become the world's third wide-body passenger aircraft player after Boeing and Airbus in Europe.
At present, the wide-body passenger aircraft being produced in the world mainly include Boeing 777 787, Airbus A330 A350XWB, etc., which almost monopolize the entire intercontinental flight.
By 2030, the international demand for wide-body passenger aircraft will reach about 8,000, and 90% of the aircraft demand will be 200-350 seatsThey believe that we will be buyers of Boeing and Airbus, but the development of the C929 may disrupt this pattern.
Let's first understand the C929 "excellent" in**. Compared with the C919 independently developed in China, the C929 has a larger fuselage, a larger passenger capacity, and can fly longer distances.
C929 uses two large bypass ratio turbofan engines, the benchmark range after successful development is 12,000 kilometers, the standard passenger load is 280 people, and the economy class adopts the standard "3-3-3" pattern, which is completely benchmarked against the Boeing 787, and the rabbit will also have a medium-wide aircraft model that can fly from Shanghai to Antarctica.
So what is the significance of C929 for China?
First of all, C929 is an important progress in China's aviation industry, and technology research and development is imperative. The research and development of C929, closer to international standards, this process is of great significance, will promote China to accumulate more technology and experience, improve China's aviation technology level, and after the successful research and development, China's aerospace industry international competitiveness will also be on a higher level. You know, at present, the only wide-body passenger aircraft in the world are Boeing and Airbus, and the research and development of C929 means that we will become the world's third largest wide-body passenger aircraft player, and the civil aviation industry will step into the world's leading ranks.
Secondly, the future commercial market can be expected, and we must lay out in advance to promote industrial upgrading. If the international market demand for wide-body passenger aircraft in 2030 is really as promising as international civil aviation, then China will meet its own domestic and foreign market demand at the same time, it will also enter the international market and gain more business opportunities, drive the development of China's civil aviation industry, and accelerate the upgrading of China's industry to the middle and high-end.
Finally, it is to enhance the country's reputation and image as a whole. As we all know, in recent years, we should see the situation of Da Mao clearly and be vigilant, and we must always keep moving forward in heavy equipment technology, otherwise it will be someone else's fish and meat on the board to be slaughtered. China has a lot of core technologies, in order to establish a good image in the international community, enhance the international influence and status.
Although Russia parted ways with China on C929, it did not affect the cooperation and progress of the two countries in other fields. The first flight of the Il-96-400M is a project that Russia has been preparing for a long time, and for the current Russia, it has its necessity, which has nothing to do with the "cooperative disintegration of the CR929 project".
After the end of China's cooperation with Russia, China's C929 is still in the process of orderly R&D and design, and will be promoted to the international market in the future, giving a dream wing for China's international competitiveness and domestic industrial upgrading.
