When Huang Keping noticed the surprise look on Yang Fan's face, he also smiled.

To be honest, after making this decision, he felt much more relaxed, as if he had seen hope for successful surveying and mapping and imitation.

Chief Secretary Pan sat next to him and didn't say anything. After hearing this decision, he laughed happily and couldn't help but say, "If this kind of high-temperature alloy is successfully purchased, it will be a great blessing!"

The atmosphere became relaxed.

After chatting for a while, he naturally talked about the future power system of the 052 ship. Huang Keping said appreciatively: "Xiao Yang, time proves that you are correct, and your vision is really long-term. At that time, it was not only recommended to buy a few more lm2500 gas turbines from the United States, but also designed an increased power cabin for our 052 ship. If other models of gas turbines are replaced, there will be no need to change the power cabin, which will save a lot of trouble."

Chief Secretary Pan also agreed: "This power cabin design avoids major surgery on the power cabin and even the hull of the 052 ship."

Without major surgery, you can directly hoist the new alternative gas turbine, which is very convenient.

Huang Keping nodded and continued: "Xiao Yang, we have begun contacting the Soviet Union and are interested in purchasing their ugt-15000 gas turbine. If there is any progress, you can send a team to inspect. You must be prepared to go to the Soviet Union for an inspection."

Go to the Soviet Union for an inspection!

Suddenly, Yang Fan felt another surprise. This was a great opportunity. The Soviet Union is not far from disintegration, and there are opportunities everywhere. Can we take the opportunity to pack and bring back their gas turbine technology? For example, the more advanced and more powerful UGT-25000 gas turbine they are developing.

The Soviet Union had complete models of ship-use gas turbines, from ugt-3000, ugt-6000, to ugt-15000 gas turbines, and ugt-25000 gas turbines.

Yang Fan thought to himself that at this time, they have completed the comprehensive design of the ugt-25000 gas turbine, and the first test prototype should be manufactured.

If you really go to the Soviet Union for inspection, you should not only look at the ugt-15000 gas turbine, but also look at the ugt-25000 gas turbine.

To be honest, Yang Fan looked down on the ugt-15000 gas turbine at all, thinking that it was not the most ideal alternative gas turbine for the 052 ship.

Only the ugt-25000 gas turbine is an ideal replacement for the 052 ship because it is more advanced and has greater power. If our future 052 ship is installed, it will have strong power.

If the ugt-15000 gas turbine is used as the power of the future 052 ship, it is not impossible, but the power is weaker, and the maximum speed will drop by at least two or three knots, which may be more than 100% if it is weaker.

In terms of power alone, the ugt-25000 gas turbine is much larger. It weighs only 16 tons but has 29 megawatts of power, while the ugt-15000 gas turbine has only 16 megawatts of power, the former is almost twice the latter.

At the same time, Yang Fan knew that the enlarged power chamber of the 052 ship was designed for the ugt-25000 gas turbine. If you put them down, there would be no problem.

In the office, Commander Huang and Yang Fan chatted for a long time.

After seeing off Commander Huang and returning to his office, Yang Fan was still a little uneasy and was still thinking about how to get the entire set of technical information of the ugt-25000 model, or even make a prototype.

Of course, I also know that this is extremely difficult, and requires enough luck and how high the price the country can offer to the other party.

.........

The time spans 1990 and enters 1991.

Ship 2 successfully entered outfitting in October 1990, and the design of the missile vertical launch system also entered the final stage, and a large number of design drawings have been drawn.

There are nearly a thousand design drawings, and there are more than 2,000 large and small drawings. There is no problem in completing the comprehensive design in one or two months.

In a few months, the surveying and mapping of the parts of the lm2500 gas turbine were basically completed. All the parts with relatively simple structures had design drawings.

Not long ago, Liu Hui arrived at the Donghai Institute again and sat in Yang Fan's office for most of the day. The two chatted for a long time.

After the design drawings of the parts came out, Xi'an Airlines Group began to try to imitate some parts, but only those types of turbine blades cannot be imitated for the time being.

As for the surveying and mapping work, it has been basically completed. The designers have begun drawing the design drawings based on the surveying and mapping data.

High temperature alloy materials for making them are temporarily lacking.

However, the General Command has been actively contacting the Soviet Union, and the progress is not bad. Reliable news comes, and it is estimated that you can go to the Soviet Union in a few months.

The list of people who went to the Soviet Union for inspection has been basically determined, including Yang Fan of Donghai, Li Zhengjun, deputy director of the power system design office, and Han Jiang, the design team leader.

Xi'an Airlines Group has three people including Liu Hui, and in addition, there are several people from the military and the general command center. It is said that Huang Keping, the commander-in-chief of the 052 ship, will be led by Huang Keping.

Commander Huang personally led the team. With such a high standard, we have great hope for the importance we attach to this inspection.

Not only should we negotiate with the other party specifically on the purchase of high-temperature alloys, but we should also talk about the introduction of ship-purpose gas turbines. Whether it is high-temperature alloys or gas turbines, they are all in the Soviet Union's "Shuguang" Mechanical Design Bureau (i.e. md).

Knowing that things were going well, they might be heading to the Soviet Union in a few months. Yang Fan was slightly excited and thought a lot in advance.

.........

February 24.

The weather is still relatively cold, and it is still in the Lunar New Year. There are still a few days left before the fifteenth day of the first lunar month, but the dock of the Donghai Shipyard has been vacated and the first ship is about to welcome the arrival of the first ship.

Whether it is the Donghai Institute or the Donghai Shipyard, all of them have officially started work. On the second day of work, Yang Fan even convened everyone to hold a meeting to deploy the end of the missile vertical launch system design.

The design is coming to an end, and the drawings have basically been drawn. Yang Fan plans to complete the full design acceptance around mid-March, and then starts to manufacture the first missile vertical launch system.

Today, Yang Fan arrived at the Donghai Shipyard early in the morning. Because the first ship had completed all navigation tests, he was about to return and dock at the dock of the Donghai Shipyard.

The test is completed, and the next step is to deliver the 052 ship to the Navy, which will begin its service and begin its decades-long service career.

After parking the car, Yang Fan walked directly into Chen Shaohua's office and asked loudly: "Old Chen, when will our first ship arrive at the dock?"

While pouring hot tea for Yang Fan, Chen Shaohua replied: "It's still an hour away, it's cold outside. There's no need for us to go to the pier to blow the cold wind now. Let's sit and drink tea first, and then go over."

Yang Fan sat down and said with a smile and joked: "Welcome to our first ship, I'll be happy to blow the cold wind!"

Chen Shaohua burst into laughter.

He is extremely happy to say what he says in his heart!

Now he has a little unreal feeling that our first ship can be delivered and will begin to be put into service.

The two talked and laughed, and after chatting, they were all very moved.

Chen Shaohua sighed: "From the design demonstration in 1983 to the delivery in 1991, our first ship took a total of eight years. In a flash, eight years passed!"

yes!

Eight years spans from 1983 to 1991.

Yang Fan nodded deeply with consent, and scenes of these years appeared in his mind. Everything seemed to be just yesterday, so clear.

"Old Chen, in eight years, we finally completed this difficult task. What is it called "Eight Years of Fighting a Ship"

One ship in eight years!

Chen Shaohua's eyes shimmered slightly and he agreed: "This is too appropriate. It's indeed eight years to beat a ship."

The two chatted for about half an hour. Yang Fan raised his hand to look at the time and reminded him: "The time is almost over, we can go there now."

"Walk."

Chen Shaohua stood up and waved his hand in front. The two of them left the office one by one and walked directly towards the dock.

From a distance, I saw that there were already many people beside the originally empty pier. They looked forward to it completely regardless of the wet and cold sea breeze.

"It should be coming soon."

"I'm really excited. Our first ship has finally completed all the tests successfully and can be delivered soon."

"I feel that all the hard work and hard work in the past is worth it."

“…….”

Standing by the dock are basically people from the Donghai Shipyard, including technicians, managers, and workers. In addition, some people from the military are also looking forward to the return of the first ship.

Yang Fan and Chen Shaohua arrived at the dock and felt everyone's enthusiasm. Listening to those proud words, they looked at each other and smiled.

"Look, that should be our first ship!"

Someone had sharp eyes and saw a ship's shadow appearing on the plane in the distance. It was just a small black dot, very vague, so he shouted loudly.

Many people stretched their necks and looked around.

Will it be our first ship?

After a few minutes, it became much clearer and someone shouted excitedly: "That's right, that's our first ship, it is heading towards this side."

The first ship is back.

Complete all the experiments and it is back!

In everyone's eyes, the distance was getting closer and closer. After a few minutes, I finally approached the dock and slowly moved closer.

An excited shout rang out.

Then, there was another warm applause.

It lasts for a long time!

Some people, like chicken blood, couldn't stop for a moment, clapping and shouting, just like a child.

The first ship successfully docked at the dock.

Next, the people from the Donghai Shipyard were busy driving. Not only did they dress up the 052 ship, but they also cleared out the wharf and made grand arrangements.

A few days later will be the delivery ceremony.

It is destined to be more grand, more lively and more festive than the launch ceremony.

In eight years, the first ship of the 052 ship can finally be delivered, which will undoubtedly be a highlight in the entire history of the construction of the 052 ship.
