Chapter 3017: Why are you so big

The path Xiong Guo took is completely different from that of the West.
The West adopts the core machine method. The core machine is first developed. After it comes out, it can be used in many ways and blossom everywhere. The Xiong Country is a special fund. What development is needed. One hammer and one hammer, of course. , And only the bear country has this kind of ability. Other countries play like this, and they have long been ruined by high research and development expenses.
In all fairness, the performance of this D-436 engine is good and it is a good choice. However, Han Guo also has its own mature power system on the Yun-10 passenger aircraft. This is the core engine of the turbofan 10. Coupled with a large external duct, the engine is made specifically for passenger aircraft. This engine is now quite mature and has experienced a lot of flying hours.
This core aircraft is actually used in many aircraft in the West. After all, it is actually a surveying and mapping imitation product of the F110. The core aircraft of the F110 is also the core aircraft of the main western CFM56 passenger aircraft engine. A core aircraft with different equipment The external ducts of the engine get a different power system. Therefore, although this engine is very advanced, it is not needed by itself.
If it is the parallel time and space, Han is very eager for this engine. After all, Han’s Yun-20 relies on this kind of power system. In order to be able to control production in its own hands, Han even eventually With a huge sum of money, he acquired 51% of the shares in Madassic and took the company into his own hands.
So now, Vladimir's expectations are destined to fail. Qin Guan took his brochure and turned to the last page: "Tell us about this D-18T engine."
This is the last page. The expectation just now fell through. Vladimir was a little disappointed. He could only continue to introduce to Qin Guan: "This engine was developed for the An-124 transport aircraft back then. The thrust of the Taiwan is 23.4 tons, with a reverse thrust device."
The contents he introduced are all in the brochure. After all, this engine is their biggest, and it was brought here mainly to show off their technical prowess. At present, they simply cannot find this kind of engine in Han. According to the intent of the demand, the Han country wants such a large engine, it is useless at all, unless they have any special military bomber project?
When thinking of this, Qin Guan said: "Does this engine have the potential to increase the thrust to 32 tons?"
Thrust increased to 32 tons? Hearing Qin Guan's question, Vladimir was taken aback: "What do you want such a big engine for?"
For a mature engine, it is not too difficult to increase thrust. Anyway, passenger aircraft engine does not require high mobility. By adding external ducts, that is, replacing fan blades with larger diameters, the engine can be improved. The thrust of the Western engine, a core machine, and different fan blades get different power. That's it.
They naturally have this technology, but it is not necessary.
If the thrust is increased to 32 tons, that means, what kind of aircraft are they going to develop? I'm afraid it's even more advanced than An-225. Are they going to build the world's first flying monster?
What Vladimir was looking forward to most was to promote the D-436 engine. As a result, people were not interested. He hadn't planned to sell the D-18T, but they came up with a request for improvement?
In this way, the thrust of a modified engine is almost equivalent to the thrust of four D36 engines.
Now it was Vladimir’s turn to question. Looking at his gaze, Qin Guan smiled and said,
It’s not a secret. We plan to develop a new airliner, code-named C929. A large dual-aisle wide-body airliner, so it needs a powerful engine to support it."
Large, dual-aisle, wide-body airliner? The question in Vladimir’s eyes is even greater. Even for such a dual-aisle wide-body airliner, there is no need for the sky-defying figure of 32 tons, right? No matter how big it is, can it be bigger than the An-124 airliner?
Seeing the other person's continued questioning expression, Qin Guan patted his head: "Oh, I forgot to tell you, our airliner is a twin-engine airliner."
Twin-engine airliner? This time, Vladimir's face became even more ugly: "How is this possible? Such a long-range passenger plane has four engines."
With the continuous development of passenger aircraft and the continuous advancement of technology, it has become more and more unified now. The long-range mainline passenger aircraft uses four engines and hung under the wings, and the short-range regional passenger aircraft uses two engines. , Hung under the wing, the third release bureau at the tail has been abandoned, too insecure.
Up to now, there has never been a long-distance trunk airliner that uses two-engine layout!
What I have seen now is the Boeing 767. The engine required for this aircraft is only 22 tons. The current D-18T engine is definitely enough. Therefore, the engine power that Han Guo needs is so strong, it shows that they The aircraft is bigger than the Boeing 767.
"We know that at the beginning of the jet era in civil aviation, the power of the engine was not particularly strong. Therefore, the dual-engine design of civil aviation was generally underpowered, so that it could not be used as a large trunk airliner and could only be used as a short-haul or branch line Passenger aircraft; and if you want to fly intercontinental, you must use a four-engine solution. In this case, the power is abundant and strong, but the economy has become a problem again. In the past, it was There is no way, but now, with the advancement of technology, dual-engine long-range passenger aircraft will inevitably become a trend. After all, the cost of two engines is much smaller than four."
Even in terms of thrust, the four existing engines have the same thrust as the two engines to be developed, but the fuel consumption of the four engines is definitely higher. At the same time, the maintenance and maintenance of the four engines is definitely better than Two engines are much more complicated. Therefore, as long as a dual-engine long-range passenger plane that satisfies the market can be launched, the four-engine passenger plane will be quickly eliminated.
Although there is no such twin-engine aircraft of the C929 class yet, Boeing has already begun to move. Their Boeing 777 is this type of passenger aircraft. It uses two engines for intercontinental flight. It is still a comfortable double-engine aircraft. Channel wide-body airliners, if you want to compete with them, you must have the same type of products.
For this kind of passenger aircraft, the engine's entry-level thrust must reach 32 tons. Only in this way can it have surging power to promote this aircraft for intercontinental flight.
