Chapter 21 ML2500 Gas Turbine

The document was transferred from above to the East China Sea Ship Design Institute. This document stated that country M basically agreed to our request to send people to investigate.

As early as a few months ago, Pan Jinfu began to consider the power system of the 052 ship shortly after he was appointed as the chief designer of the 052 ship.

Compared with the 051 ship, the future 052 ship must have a qualitative leap, and its power system can no longer use steam turbines as power like the 051 ship. According to Pan Jinfu's vision, it should be diesel powered, that is, there are both diesel engines and diesel engines. gas turbine.

Adopting such a power combination has many advantages, not only the fuel utilization rate is greatly improved, but also the volume of the power system is greatly reduced, which can save a lot of cabin capacity.

Diesel-fuel power combination is generally propelled by a relatively economical diesel engine, and a gas turbine is used when high-speed sailing is required.

After carefully reading this document, Pan Jinfu was in a good mood and thought happily that country M really agreed to send people to investigate. It seems that the introduction of their LM2500 gas turbine from General Electric is very promising.

It's not too late, it needs to be done as soon as possible.

In Pan Jinfu's view, the urgency of it is much higher than sending people to country F to inspect the combat system.Because the first thing to be determined in ship design is the power system.

This is the same as designing an aircraft by first determining the engine and flight performance indicators, then designing the aerodynamic shape, and finally integrating the combat system.

The power system goes first, and the combat system can be slightly behind.Besides, it is still early to send people to country F to inspect its combat system. On the one hand, the upper management needs to communicate with country F, and the other party agrees to send people to investigate. On the other hand, Pan Jinfu sent people to country F to inspect It hasn't been long since the report was submitted, and it will take time for a reply.

After determining the power system, new ships start to consider indicators such as voyage, speed, self-sustaining force, anti-sinking, seaworthiness, and maneuverability.

In other words, if the power system is not determined, a lot of work cannot be carried out.No wonder Pan Jinfu is so happy. If General Electric's LM2500 gas turbine can be successfully introduced, then the design and demonstration work of the 052 ship will take a big step forward.

Since it is possible to send people to the General Electric Company for investigation, it is not too late. Pan Jinfu picked up a pen and began to write. Soon, a report gradually took shape.

There are always some "informed people" in the East China Sea Ship Design Institute, which may be due to the lack of entertainment programs in this era. People always look for something to talk about, and some people always talk about something quietly.

Ship 052 plans to adopt General Electric's LM2500 gas turbines. This matter is spread within a small area of ​​the East China Sea Design Institute. Of course, everyone knows the importance of confidentiality. The spread is limited to the East China Sea Institute. This kind of thing will never be spread. go outside.

In Yang Fan's large office, most of the people are immersed in their work and are very serious. Some people will take a break after getting tired, such as drinking a sip of tea and simply chatting with colleagues next to them.

No, several people are talking about the demonstration of the 052 ship's power system.

"It's basically decided. Our 052 ship will be powered by diesel fuel. It is initially planned to use two gas turbines and two diesel engines as power."

"This is much more advanced than the 051 ship. Our 051 ship still uses steam turbines."

"We don't have the gas turbines needed for the 052 ship in China, so we should import them from abroad."

"It must be imported. I heard that it is going to import gas turbines from General Electric Company. I don't know the specific model yet."

"Imported from General Electric! Boy, that's probably the most advanced gas turbine in the world."

"."

These colleagues were beaming with joy, chatting excitedly like this, their voices became louder and louder, almost verbatim what they were talking about entered into Yang Fan's ears.

"It turns out that the power scheme has been initially determined. Well, it has entered the stage of comprehensive design and demonstration of the 052 ship. It is true that the power system scheme should be finalized as soon as possible." Yang Fan thought to himself.

As an excellent ship designer of the Republic, Yang Fan naturally knows the importance of the power system, and is also very familiar with the power system of the 052 ship.

In the early days, the military required the 052 ship to use gas turbines as power instead of continuing to use steam turbines like the 051 ship.

The 052 ship adopted the CODOG scheme of alternating diesel fuel at the beginning, and now it has entered the comprehensive design and demonstration stage of the 052 ship. Yang Fan guessed that Chief Master Pan should have many ideas in his mind, and the scheme of alternating diesel fuel may have already taken shape.

just
Familiar with the development history of the 052 ship, Yang Fan is very worried about the 052 ship using GM's LM2500 gas turbine as power.

In history, the 052 ship has taken many detours, and it has been extremely difficult along the way, including the cut off of the supply of LM2500 gas turbines by the United States.

Because of the outage of the LM2500 gas turbine, the No. 052 ship of our 2 ship almost died.

In the middle and early 80s, we and the United States were in the honeymoon period. We proposed to import LM2500 gas turbines as the power of the 052 ship. The United States agreed immediately, and also agreed to carry out technology authorization and transfer.

这让很多人无比的欣喜，052舰也顺利的确定采用LM2500作为动力，并一共从美国进口了4台LM2500燃气轮机，以及1台用于培训、实验的LM2500样机。

However, the international situation changed at the end of the 80s. Western countries initiated a ban on the export of weapons technology and equipment to my country. The introduction of LM2500 was blocked, and there were no more LM2500 gas turbines.

In this case, the design of the 052 ship has to be reconsidered. What's worse is the combat system of the second ship of the 052 ship. A considerable amount of hull structural materials have been produced and will be built on the berth soon.

The construction of the second ship even faced cancellation for a time.

If the construction is cancelled, it means that those things produced for the second ship will be idle, which is an incomparably huge waste
Knowing these things well, Yang Fan saw that there was no deviation, and the 052 ship would still use General Electric's LM2500 gas turbines. He felt a little heavy and seemed extremely helpless.

"Ugh"

Apart from sighing softly, Yang Fan really has no better way. He can’t go to Pan Jinfu and say loudly that the LM2500 gas turbine cannot be used. The Americans will cut off our supply later, leaving us in a situation where there are no gas turbines available. .

If that is the case, it is undoubtedly a neurosis.

"Yang Fan, what's wrong?"

Not far away, Zhang Xiaodong noticed that Yang Fan was in a low mood, and seeing that he even sighed, he asked with concern.

Yang Fan shook his head, "It's okay, I suddenly remembered something, and I just felt a little bad all of a sudden."

Of course, I can't say the real reason. This matter can only be hidden in my heart for the time being, and no one can say it.

In the meeting room, Pan Jinfu is presiding over the meeting.

Not only Tang Jianming, the deputy chief designer of the 052 ship, Zhao Yulan, the director of the Type Office of the 052 ship, but also the design leaders of various subsystems, such as Shen Bin, the design leader of the power system, participated in the meeting.

There were also a few senior designers in the institute, and many people attended the meeting, a total of more than a dozen people. This meeting mainly discussed matters related to the LM2500 gas turbine.

Pan Jinfu seemed to be in a very good mood, and said in a slightly excited tone: "Comrades, things are becoming clearer and clearer. The superiors have approved the fact that we sent people to General Electric for investigation. It seems that the introduction of LM2500 gas turbines as the power of our 052 ship is very important. has hope."
