The military-industrial scientific research system of the academic master.

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

It is impossible for Yan Zhongcheng to spend several hours explaining the technical points of aviation fuel conversion.

Besides, he hasn't really started taking over the design work of QC300 yet, so even if he wanted to talk about it, he can't say much for the time being.

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

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

As for the comparison between the two models...

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 will be a matter for later.

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"...

Not to mention that the latter has the upper hand, at least the balance has begun to swing left and right -

Both sides mentioned the indirect cooling and heat recovery technology.

Even the contents are similar, and the plagiarism rate is unlikely to pass the initial review of the graduation thesis.

And they are all empty promises.

Everyone originally thought that the special design that enables stable operation under low operating conditions was the trump card of 703.

When I looked back, I saw that the person next to me had also taken out... a shuriken?

In short, the styles are different, but the functions are similar.

The meeting room fell silent for a moment.

Everyone is thinking.

For Wen Xueyou, the only weakness that his competitors can currently point out is the uncertainty in the research and development process.

After all, the adjustable stator blade matching technology involves modifications to the high-pressure compressor, and the risk is much higher than the 703 Institute's plan of only adjusting the casing.

But firstly, we are all decent people, and it is not appropriate to be too aggressive in such occasions.

Secondly, someone has just brought up the example of WS-10.

It's not exactly the same thing, but it's certainly convincing.

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

"Mr. 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 position of deputy director and chief designer of the 701 Institute.

He is the successor of the senior academician Pan Jingfu.

“Originally there was…”

Zhu Fuying exhaled helplessly, then straightened his messy gray hair:

"However, the design of the 052C...is actually mainly about shipborne equipment. It has undergone a major adjustment in the middle, which has occupied many projects that were planned to be deployed in the next upgrade."

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

Speaking of improvements, there are actually quite a few areas that need improvement on the first two 052Cs.

First of all, the new universal vertical launch system has a caliber of up to 850mm. Although its arrangement is denser, it occupies a larger area than the previous special vertical launch system used exclusively for the HQ-9.

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

This "universal" vertical launch is mainly for future warfare considerations. At present, there is actually no second type of missile available except the HQ-9, and the Chinese Navy is in urgent need of anti-sea strike means.

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

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

Not only is the firepower sustainability insufficient, it is also very unfriendly to people with obsessive-compulsive disorder.

Therefore, in the future, we must develop an anti-ship missile that is compatible with vertical launch, and remove the unsightly 8-round Eagle Strike 62 and replace it with a vertical launch.

He even reserved space in the ship.

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 for it to occupy a separate 052D model.

But then again, if we want to fundamentally solve the problem of insufficient space in the ship, the workload will be huge...

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

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

"But if we can get a more powerful engine, we can also consider further modification 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 8000 tons. This can completely solve the problem of tight space in the hull, and even re-set up a double hangar..."

Obviously, as a mere technician, he did not want to show too obvious tendency, so he introduced both current ideas.

"Will the second option be too technically difficult? I mean...if we adjust the hull?"

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

“The technical difficulty is actually not that bad.”

Zhu Fuying replied:

"Although the 052 is a series, the hull has undergone a large-scale modification from the earliest 052 to the current 052B/C, so if we need to modify it again... we have the experience."

"But considering that this change is not a simple enlargement, but also involves internal structural adjustments, the workload will indeed increase a lot, and the R&D cycle may be longer. At least we can't make and modify at the same time. I'm afraid we will have to 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 it would be six to eight years.

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

If the gas turbine itself could be developed in time, then the development of the hull alone would not take so long, so the plan was changed halfway.

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.

According to the original plan, even if the construction of 052C continues, it will not start to increase in volume until GT25000 is fully domestically produced.

It will probably take about two years.

Now, just wait a year or two longer to get a completely upgraded model.

It’s a great profit.

But in this case, the choice of importing and localizing GT25000 seems a bit clownish...

The 703 Institute, which took on this task and even upgraded it...

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

Although Li Jiang had no idea about this, he also felt that it seemed inappropriate.

He turned his head slightly and glanced at Wen Xueyou, who looked a little unhappy.

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

"Boss Yan, Boss Wen, after listening to your introductions, I have an immature idea."

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

"The proposal put forward by Mr. Yan is to modify the design of the stationary blades of the high-pressure compressor, while Mr. Wen's proposal is to open the casing at the leading and trailing edges of the moving blades. However, the ultimate goal is to achieve performance optimization at non-design points."

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

After hearing his suggestion, the two main parties did not express their opinions immediately, but just lowered their heads in thought without saying a word.

But Li Jiang's eyes lit up instantly.
