Chapter 990: Adults Choose to Have It All

After all, it was not a formal selection, and there were not many experts in the field of gas turbines sitting below.

Yan Zhongcheng could not spend several hours to explain the technical points of aviation-to-gas conversion.

Besides, he had not really started to take over the design work of QC300, and even if he wanted to talk, he could not say much for the time being.

Even today when the WS-10 has been finalized, Chang Haonan is still the only one who can really understand the design points of this model from the inside out.

In short, Yan Zhongcheng spent about twenty minutes to introduce all the content he prepared.

As for the comparison results of the two models...

There is no result.

The core purpose of today's symposium is still for communication.

The navy must first determine its next shipbuilding plan.

As for the selection, that is a matter for the future.

Of course, everyone still has a scale in their hearts.

Originally, after Wen Xueyou finished speaking, most people thought that "the old model is still reliable in the short term."

As a result, now, a considerable part of them has become "the new model seems to be quite stable"...

Let's not say that the latter has an advantage, at least the balance has begun to swing left and right--

Both sides mentioned the intercooling and heat recovery technology.

Even the content is similar, and the plagiarism rate is suspected to not pass the initial review of the graduation thesis.

And it's all empty talk.

And the special design of stable operation under low working conditions was originally thought to be the trump card of the 703 Institute.

But when I looked back, the next door also took out a... shuriken?

In short, the style is different, but the function is similar.

The conference room was silent for a while.

Everyone was thinking.

For Wen Xueyou, the only weakness that the opponent can bring out at present is the uncertainty of the research and development process.

After all, the adjustable stator matching technology involves modifying the high-pressure compressor, which is much more risky than the 703 Institute's solution of only adjusting the casing.

But on the one hand, everyone is a decent person, and it is not good to be too aggressive in such an occasion.

On the other hand, others just brought out the example of the turbofan 10.

Although it is not exactly the same thing, it is indeed very convincing.

For the Navy and the participants in charge of the overall design, there are more things to consider...

"General Zhu, do you have a more mature plan for the subsequent improvement of 052C... or at least an idea?"

Li Jiang, the head of the Navy Equipment Department, who was sitting in the first seat, looked at Zhu Fuying next to him and asked first.

The latter is the chief designer of the 052B/C models. Of course, he has now been transferred to the deputy director and chief designer of the 701 Institute.

He is the successor of the old predecessor Academician Pan Jingfu.

"Originally, there was..."

Zhu Fuying exhaled a breath of turbid air with some helplessness, and then sorted out his messy gray hair:

"But the design of 052C... is actually mainly shipborne equipment. It has undergone a major adjustment in the middle, and many projects planned to be deployed in the next upgrade have been occupied in advance."

Even for the experienced Zhu Fuying, this situation is really rare-

If you want to talk about improvements, there are actually many places that need to be improved in the first two 052Cs.

First, the new universal vertical launch has a caliber of up to 850mm. Although the row is more dense, it occupies a larger area than the special vertical launch used for the HQ-9.

Secondly, the planned Z-12 has a larger footprint than the Z-9 and Ka-28 (mainly wider), and the 052 series has a relatively narrow hull width to ensure the speed. Therefore, even if the single hangar is set on the left side, there is still not much space on the other side.

And this "universal" vertical launch is mainly for the consideration of the future of war. At present, there is actually no second type of missile to be installed except the HQ-9, and the Chinese Navy is in urgent need of means of attacking the sea.

Therefore, the two inclined quadruple anti-ship missile launchers in the middle and rear of the hull are still retained...

In the end, they had to squeeze in two 8-unit vertical launchers between the anti-ship missiles and the hangar, and they were not even on the central axis of the whole ship, so they came up with a 32+16 configuration.

Not only is the firepower sustainability not enough, but it is also very unfriendly to obsessive-compulsive disorder.

Therefore, in the future, they will definitely develop an anti-ship missile that can be compatible with vertical launch, and remove the 8-round Eagle Strike 62 that is an eyesore and replace it with a vertical launch.

He even reserved space in the hull.

However, the improvement is so small that it is hard to say whether it can be singled out and called 052C(M), and it is impossible to occupy a separate 052D model.

But then again, if we want to solve the problem of insufficient space in the hull from the root, the amount of work will be huge...

After organizing his words a little, Zhu Fuying continued to explain:

"If the Navy believes that the current technical status of 052C is suitable for mass production as a main battleship, then our next step is to fine-tune and optimize the surface equipment of this type in batches to ensure that combat effectiveness and mass production capabilities are formed in the shortest possible time."

"But if we can obtain a more powerful power, we can also consider further modifications based on the current hull, reducing the length-to-width ratio from the current 8.6 to about 8.2, and increasing the displacement to 8,000 tons accordingly. This can completely solve the problem of tight hull space, and even re-set up a double hangar..."

Obviously, as a pure technician, he did not want to show too obvious tendencies, so he introduced the two current ideas.

"Would the technical difficulty of the second option be too great, I mean...if the hull is adjusted?"

As the person in charge of the equipment outlet, Li Jiang is naturally interested in more advanced options, but at the same time he has to consider the risks.

"The technical difficulty is actually pretty good."

Zhu Fuying replied:

"Although the 052 is a series, from the earliest Type 052 to the current Type 052B/C, a large-scale change has been made to the hull in the middle. So should we change it again... we also have experience."

"But considering that this change is not simply amplification, but also involves internal structural adjustment, the workload will indeed increase a lot, and the research and development cycle may be longer. At least it cannot be made and modified at the same time. I am afraid that there will be a stop in the middle... ...Uh...about three or four years..."

In fact, he originally wanted to refer to the development cycle of 052B and say six to eight years.

But then I thought about it and realized that the conditions now are completely different from those ten years ago.

If the gas turbine itself could be developed in time, then a single ship body would not take that long anyway, so he changed his mind midway.

And this seemingly casual change of words had a huge impact on Li Jiang's heart.

Waiting three to four years is completely acceptable to the Navy.

Originally, according to the plan, even if we continued to build the 052C, we would have to wait until the GT25000 was fully domestically produced before starting to increase production.

It probably takes about two years.

Now as long as you wait a year or two more, you can get a completely redesigned and upgraded model.

Make money with blood.

But in this way, the choice of introducing and localizing GT25000 seems a bit clownish...

And to undertake this task, we even built an upgraded 703 Institute on its basis...

If Chang Haonan saw this scene, he would definitely exclaim NTR in his heart.

Although Li Jiang did not have this concept, he also felt that it seemed inappropriate.

He turned his head slightly and glanced at Jacky Wen, who had a somewhat unpleasant look on his face.

At this time, another officer next to him suddenly interjected and asked Yan Zhongcheng and Wen Xueyou on the other side:

"Mr. Yan, Mr. Wen, after I just listened to your introduction, I have an immature idea."

For a moment, everyone's attention was attracted to him.

“The plan proposed by Mr. Yan is to modify the design of the stator blades of the high-pressure compressor, while Mr. Wen’s plan is to open the casing at the leading and trailing edges of the moving blades, but the ultimate goal is to achieve a very high-pressure compressor. Design point performance optimization.”

"Then... is there a possibility that you two can combine technologies and jointly develop a model with better performance..."

After listening to his suggestion, the two principals did not express their opinions immediately, but just lowered their heads in deep thought.

But Li Jiang's eyes suddenly lit up.
