Chapter 1068

After all, they had also read the drawings sent by Chu Fei at the beginning. At that time, Mr. Wu Daguan smiled and said, "This is simply nonsense. The development of the engine is not a child's house, so he can come whatever he wants... But let him play first, I think he is under a lot of pressure now!"

Yes, a 301-stage factory has been moved here, do you still care about this material?

But who would have thought that in just five days, such a "playing house" engine was released, and the data directly surpassed the world's top engine...

Here comes a concept that needs to be explained, thrust and push ratio

The greater the thrust of military aviation engines, the higher the requirements for raw material quality and manufacturing process. The higher the push ratio, the higher the technological content, and the more advanced the engine performance, just like the United States' engines have always been pushing higher data, while Russia's engines have the thrust leading all the way.

So speaking of this, the F118-GE-110 afterburnerless turbofan engine of the B-2 stealth bomber is not actually the most advanced engine in the world, because it appeared to accommodate the B-2's size and stealth needs, depending on the size and fuselage design of the B-2.

The B-2 is a flying wing layout, and in order to stealth, all fuel tanks and mountings are in the fuselage.

Although the fuselage is already relatively thick, in order to accommodate up to 22 tons of ammunition and 90 tons of fuel, the internal space of the fuselage is very tight. You should know that the data of 22 tons of ammunition is close to the maximum loading of B-52.

The F-118 is relatively small in size and is only about 25 meters long, so that the B-2 can stuff four F-118 engines into the short fuselage.

However, when B-2 chooses F-118, it is not only the diameter that compromises, because even the diameter of F-119, F-110, and F-101 is less than 12 meters; it is compromised by the inherent shortcomings of the B-2 ammunition and fuel in all built-in and wing-style layout of the B-2 ammunition and wing-style layout.

Relatively speaking, the F-119 is the most advanced engine in the world. Its thrust reaches 156 kiloN and its push ratio is as high as 117. However, it is an engine specially developed for the US F22. It was officially approved for the initial use of the US Air Force in September 2002. So at present, the F-118 is still the king of aircraft engines. Although the thrust is not large, the push ratio is incomparable to all other engines. Even Russia cannot catch up with its push ratio at this time, let alone Europe and China...

Because the push ratio of Kunlun engines in China is only 7 that can be pity...

Here is a popularization of engine knowledge. The Kunlun engine independently developed by China was also developed for upgrades. Unfortunately, it was born at the wrong time. It took 18 years before Shanshan came late. Kunlun has reached the peak of the turbojet engine, but it has lagged behind the pace of the times. Because it was in 2002, the US F-22 was born, which forced the Chinese Air Force to also start to equip a large number of third-generation aircraft. The completely backward Kunlun engine was not attracted by the Chinese Air Force at all. So until Chu Fei was reborn, there was no order. If it weren't for the Taihang engine that appeared at that time, China's engine research and development would be...

completely annihilated!

But although the data of Taihang engines are very beautiful, the push ratio is barely 9, which is not comparable to that of European engines, let alone Russian and American engines...

Not a thing of the same level at all!!

Think about it, even five years later, China's engine technology still cannot catch up with the United States. It is not difficult to explain what kind of mentality will it be when the country knows that Chu Fei has two F-118s here? What is the purpose of relocation of 301?

If possible, they even dared to bring all of China Aviation and Shenhang over!

So it is even more difficult to explain why Mr. Wu Daguan and others were shocked, because whether it is Kunlun or Taihang, it was finally unsheathed after eighteen years of hard work. Moreover, Kunlun engines are still being developed, not to mention Taihang engines that do not even have a shadow. China is still blank in the engine field so far...

But here Chu Fei had taken out the drawings directly, and then made them into one go, and then...

Be accomplished?

And it is a finished product that is more advanced than most engines in the world?

And the most important thing is that the technology of this engine is completely different from that of the United States and Russia. Not only the design concept, but also the materials, but even the assembly technology belongs to another new concept, which is what Mr. Wu Daguan said before...

Children play house!

However, after two or three days of repeated tests, they were shocked to find that the performance of this engine is outrageous, and both the function ratio and other indexes are far superior to the F-118 used by the B-2 stealth bomber!
