Chapter 72
Kuang Wei's efficiency is very high, within ten days, the new 052 ship hull design master plan came out.Of course, without expert review and acceptance, it can only be regarded as a sketch.

He took this sketch to Yang Fan's office.

In the past ten days, the combat system design room has been relatively busy, and everyone has a lot of design tasks, especially the first expert review under the organization of Yang Fan. After the review, there is a lot of work to be done.

In addition, the construction of the laboratory has also started, and the first batch of equipment and equipment has been put in place. Several people including Yang Fan and Zhang Xiaodong spent a large part of their time in the laboratory, starting the construction of the professional combat system laboratory.

When Kuang Wei came over, Yang Fan was returning to his office from the laboratory. He had just taken a breath, drank a few sips of hot tea, and was thinking about his next work.

The work for a period of time in the future will undoubtedly focus on the construction of the laboratory. In addition, the general design of the combat system will also be drafted, and then submitted to experts for review and acceptance.

The design of the 052 ship's combat system also follows the principle of first overall, then partial, and finally detailed design.Yang Fan first set up the framework and clarified the main design, and then a group of technicians began to design in detail. Of course, various verifications will inevitably be carried out during the design process. Only after verification can a formal design be formed.

"Director Yang."

Seeing Kuang Wei coming in, Yang Fan greeted him warmly, "Director Kuang is here, please take a seat."

Kuang Wei smiled and said, "I won't sit down for now. According to your suggestion last time, we have redesigned a general plan of the hull design. You can take a look."

"Oh, so fast."

Yang Fan was overjoyed, took these design sketches and spread them out on the big table next to him, and looked at them seriously.

"Director Kuang, the length of the ship has increased from 146 meters to 147.5 meters, and the width of the ship has also increased by 600 mm."

Yang Fan said while looking at the drawings.The power cabin is expanded, and the overall length and width of the corresponding 052 ship have increased.

After looking at it and feeling that there is no problem, Yang Fan asked: "After the size of the ship increases, under the same power, have you calculated the impact on the speed and range?"

Kuang Wei replied: "It has been calculated. There is a little impact, but the impact is relatively small and can basically be ignored."

There will definitely be some impact.The impact is not big, Yang Fan is completely relieved, and agrees with the design in front of him very much. With enough cabin capacity, even if the supply of LM2500 gas turbines is completely cut off in the future, UGT-25000 can be used without changing the hull design. /DA-80 gas turbine replacement.

"Director Kuang, my opinion is that this design sketch should be submitted for review together with several other sketches. How about taking a look at the opinions of the expert group?"

"No problem, we will submit the review together, and the time is set for next Monday. In addition to our experts from Donghai Institute, Donghai Shipyard, Military Industry Bureau, military, general headquarters, etc., there are a total of more than a dozen units and more than 30 people. Experts participate in the review."

The scale is really big enough.

In fact, it is also easy to understand that the overall design of the 052 ship is of great importance, involving all aspects, and cannot be taken lightly. It must be reviewed by a large number of experts.

It is estimated that the overall design of the combat system is the same. After the general design drawing is released, it is estimated that the number of experts participating in the review will only be more, not less.

Other sub-systems may not have such a large scale of review. It should be based on Donghai, and then invite some outside experts to participate.

Review next Monday.

Yang Fan felt relieved that this plan would only be submitted to the expert group, and it might be passed. As long as it passes the review of the expert group, it is a certainty, and the hull design of the 052 ship will not be changed.

The two chatted for a while, time was precious, Kuang Wei did not stay long, and returned to the general design room with the design sketch. From now on, he must prepare for the expert group review next Monday.

in the office.

Pan Jinfu is seriously looking at the blueprints sent by the general design office. They are all the general design drawings of the 052 ship. There are several kinds of general design drawings, and there are certain differences between them.

On the big table, one of the design drawings was being laid, pressed with beading bars. Pan Jinfu had been looking at it for a long time. In addition to Mr. Pan, Tang Jianming and other vice-president designers were also nearby. Everyone's eyes were also focused on above this drawing.

After looking at it for a while, one of the deputy chief designers said: "The biggest difference between this design drawing and the previous ones is the power cabin. Its cabin capacity has increased significantly."

"That's right. With the enlargement of the power cabin, the captain and the width of the ship have also increased accordingly. I personally don't think there is such a need." Another deputy chief engineer said.

Pan Jinfu didn't say anything for the time being, but just kept looking at the drawings like this, stopping to think about it from time to time.

Before submitting these drawings to the expert group for review, Pan Jinfu and others must go through them carefully. Design room redesign.

After a few more minutes, Pan Jinfu looked away from the drawings, "There are no major problems in the drawings, and these different designs are based on full consideration from different angles. Expanding the power cabin, I personally Think it’s okay.”

"Old Pan, I don't think it's necessary. The power system has already been determined. Designing such a large power cabin is a waste of cabin capacity." A deputy chief designer reminded.

Pan Jinfu smiled slightly, "Director Kuang from the General Design Office mentioned to me that the increase in cabin capacity was suggested by Yang Fan, Deputy Director of the Combat System Design Office."

what!
Fan Yang's suggestion!
Several deputy chief engineers were stunned. They always thought it was the idea of ​​the general design office, but they didn't expect it to be Yang Fan's suggestion.

"Old Pan, how could Yang Fan make such a suggestion? His job should be to complete the design of the 052 ship's combat system excellently."

Pan Jinfu said: "Our Comrade Yang Fan considers the problem more comprehensively and looks at the problem in the long term. He has been worried that the LM2500 gas turbine may be cut off in the future. With a large cabin design, in case the LM2500 gas turbine is cut off, it will be replaced by other types of gas turbines. The replacement gas turbine can be successfully installed in the power compartment."

It is easy to understand that if the power compartment is not large enough, the replacement gas turbine may not be able to fit in it.

Will the LM2500 gas turbine be cut off?
Regarding this matter, different comrades hold different opinions, but most comrades do not support this view, believing that our relationship with the United States is improving, and the possibility of cutting off the supply is too small.

A deputy chief designer said: "I think the possibility of cutting off the supply is almost negligible. Comrade Yang Fan has been worried that the supply will be cut off. Before that, he proposed to purchase 10 LM2500 gas turbines in the first batch. As a result, we signed a purchase agreement with General Electric. Formal contract for 8 gas turbines”

The deputy chief designer said a lot, but he only meant one thing. The possibility of cutting off the supply is too small. There is no need to design such a large power cabin. It can be tailored according to the currently determined power system to save the cabin capacity.

Tang Jianming kept silent. At this time, he objected: "Tailor-made can indeed save the cabin capacity, but the risk is too great. Just like what Comrade Yang Fan is worried about, what if the supply is really cut off in the future."

"As I said, this possibility is almost negligible." The deputy chief designer's voice was a little louder just now, "Even if the supply is really cut off, we don't have to worry about this in the next ten years. Not enough gas turbines."

Tang Jianming argued with the deputy chief designer. Both of them were deputy chief designers at the same level, and no one would give in to the other.

In the end, Pan Jinfu said: "Stop arguing, I don't think any of you can convince anyone, how about this, submit all these design drawings to the expert group for review and discussion, and listen to everyone's opinions."

It can only be this way.

Tang Jianming nodded in agreement, "Yes, then submit it to everyone for discussion at the review meeting next Monday, and the minority obeys the majority."

After thinking about it for a while, Pan Jinfu said, "Expanding the capacity of the power cabin was proposed by Comrade Yang Fan. Let him participate in the expert review meeting next Monday."
