Although the C929 wide-body large airliner was born a little late, it is more than just a passenger aircraft.
You must know that although the Chinese Air Force has a large transport aircraft such as the Y-20, it is not very suitable to use the Y-20 to change early warning aircraft, tankers, and electronic warfare aircraft.
Because almost all of the world's mainstream early warning aircraft and tanker aircraft are modified from large passenger aircraft, such as the E767 early warning aircraft and E3 watchtower early warning aircraft in the United States, which are modified from Boeing 767 passenger aircraft and Boeing 707 passenger aircraft.
The reason why a large civil airliner is used to modify an early warning aircraft is because the economy of a civil airliner is better, and at the same time, its fuselage resistance is much smaller than that of a large transport aircraft, and the speed is also faster.
The large military transport aircraft, by the fat is too fat, not only the fuel economy is not good, the empty time and endurance are also worse, of course, there is also a point that the ergonomics are far inferior to the civilian airliner, because the civilian airliner was designed for comfort at the beginning, and the large military transport aircraft is much worse in this regard.
In terms of modifying military special aircraft, the C929 large wide-body passenger aircraft can be said to have too obvious advantages.
If you use C919 to modify, it is a little too small, after all, the C919 passenger aircraft is only a level with the Boeing 737 passenger aircraft, and the maximum take-off weight is less than 100 tons, so its range, air time, etc. are far inferior to the C929 large wide-body passenger aircraft.
You must know that the only countries that can design and produce large wide-body passenger aircraft in the world are the Boeing Company of the United States and the European Airbus, and the representative models of the two companies in the eight or nine years and the tenth generation are the Boeing 747 and the Airbus A350, both of which are 350-seater.
In the new century, Airbus produced the Airbus A380 airliner, and Boeing launched the Boeing 787 Dreamliner.
The A380 airliner, second only to the Antonov AN225 transport aircraft, has been in service since 2007 and has been fraught with controversy since its debut.
Because it is the largest passenger aircraft in the world, with a double-decker cabin, and four turbofan engines with the largest single thrust, the number of passengers is also the largest, reaching 555 seats, and what is even more amazing is that in the cabin of this passenger plane, there are retro gangways, bars, showers, gyms, suites, and even duty-free shops and plunge pools, the luxury is comparable to those top sea cruise ships.
Of course, these are nothing, and the most amazing thing is how big it is.
The length and wingspan of this large passenger plane have reached more than 70 meters, close to more than 80, and the height is equivalent to a seven-story building.
The maximum take-off weight can reach 560 tons, the maximum load capacity is 150 tons, and it can carry 310,000 liters of fuel.
It's just that this large passenger plane has big successes and big failures.
It is precisely because it is too big, too heavy, and too expensive, so its order volume is ultimately too small, which makes Airbus lose a lot of money, and because it is too big and heavy to land at an ordinary airport, it is destined to be unable to be converted into a military special aircraft.
The Boeing 787 Dreamliner of Boeing is also a very controversial airliner.
It is also a twin-engine wide-body airliner with a 300-seat aircraft, somewhat similar to the C929.
With fuel consumption comparable to that of the Boeing 767 and A330, this airliner can fly at Mach 0.98 at close to the speed of sound, while the average airliner can only reach Mach 0.8 to Mach 0.9.
This is because it uses a lot of composite materials, the fuselage is lighter than ordinary airliners, and it has very advanced aerodynamic efficiency.
In the seventies and eighties, the United States had a refueling aircraft modified from the Boeing 707 passenger plane and the McDonnell Douglas DC10 passenger aircraft, and in the new century, the latest refueling aircraft and early warning aircraft were modified from the more mature Boeing 767, without exception, they were modified by large civilian passenger aircraft.
In addition to the purchase of American tankers, European tankers are also modified from Airbus A330 and A310.
Therefore, the civil airliner is the best choice for modifying military special aircraft, only Da Mao is the use of Il-76 large transport aircraft to modify the tanker Il-78, as well as early warning aircraft A50, the disadvantages of modification with large transport aircraft are obvious, although it has a large fuel reserve, suitable for in-flight refueling of a variety of models, but the use of Il-76 military transport aircraft platform, both economy and multi-purpose compared with the same level of KC-767 and KC-46A are far away.
The Il-78 can only use hoses, which makes it less efficient than hard hose fueling machines.
In the same way, the conversion of the Y-20 into an air tanker aircraft will also have the above problems.
Therefore, in the future, the air tanker suitable for the Chinese Air Force is still better to use the civil airliner platform, and the optional civil airliner platform is only C919 and C929, and in the long run, the most suitable is of course the C929 with longer fuel load and empty time.
Shen Huan was not only a shipbuilding engineer in his previous life, but also a senior military fan, so he knew all about these very well, and was even more professional than the so-called experts on some TV shows, so he was favored by top aircraft design masters like Chief Tang Weiwen, and specially invited him to fly to the west for an exchange visit.
He is most aware of the future development of China's large passenger aircraft and the development of regional passenger aircraft.
Xifei and 603 are factories specializing in large transport aircraft and passenger aircraft, and Chief Engineer Tang Weiwen is a leader in large passenger aircraft, transport aircraft, and bombers in the future.
So of course Shen Huan will not be stingy, and give the technology of the pulsating production line to Tang Weiwen, the chief engineer of the aviation industry department, and other aviation industry factories, if all aircraft factories have pulsating production lines, then in the future, China's aviation industry will definitely be able to keep pace with the United States and Europe, and even surpass them.
After listening to Shen Huan's opinions on independent research and development or seeking cooperation with foreign countries, Chief Engineer Fu Jianshe nodded and said: "Yes, the reason why Embraer has succeeded in the field of regional airliners is that they know how to aim at positioning, how to integrate international aviation industry resources, and at the same time firmly grasp independent design and construction, so I think what you just said is the most suitable for us to combine the two."
This is true in the aviation industry, and it is not the same in the field of shipbuilding!
” Shen Huan couldn't help but sigh: "Yes, take the shipbuilding industry of the stick country as an example, their start is not too early, before the seventies, the world shipbuilding market was dominated by Europe and the foot basin country.
Due to the high cost of the shipbuilding industry in the United States, it only focuses on the construction of warships, and the same is true for the woolly bear.
At the beginning of the seventies, the shipbuilding industry of the stick country was even inferior to ours, it was equivalent to starting from scratch.
They adopted the method of introducing complete sets of production equipment and importing core components for assembly and production, which is almost the same as the development of the Brazilian aviation industry.
We don't like sticks, but we have to learn from them!
