Yao Yuan's speech at the Avionics Research Institute shocked Zhu Yingjie and others and left an indelible mark in their hearts. Yao Yuan's speech to them, who represent the national team of ship design, will undoubtedly have a profound impact on them.

Subsequent design.

The emergence of integrated ship electronic systems (integrated ship electronics technology) that spanned two decades has suddenly placed the electronic technology of Chinese ships at the forefront of the world. Its significance and far-reaching significance cannot be overstated.

Relatively speaking, the all-diesel combined power plant is not so dazzling.

The so-called all-diesel combined power plant refers to a diesel-diesel combined power plant, which literally means that all diesel engines are used as the main engine.

There are two modes in the use of ships. To improve the combat effectiveness of military ships, they should increase the two indicators of speed and maneuverability as much as possible. Specific to combat ships such as destroyers, frigates, and aircraft carriers, they are required to reach 30 knots when sailing at full speed.

.

However, this working condition accounts for a very small proportion of the total sailing time of the ship. To put it bluntly, it is rarely used, only about 1%.

From the perspective of the two indicators of cruising power and self-sustaining power of military ships, the power plant is required to have good economy and to increase the maximum range as much as possible. Generally, the cruising speed of 16 knots shall prevail, and the farthest it can sail under full load.

The distance is the maximum range.

These two working conditions are actually opposite. To sail at full speed, you must run at full power, and the range will inevitably be affected. However, if you want to be economical, you must sacrifice speed and maneuverability. This is a contradiction.

In order to solve this problem, the combined power plant appeared.

Simply put, it means using the same type of main engine or different main engines, and changing the engine, propeller and operating mode of the propulsion device according to different working conditions.

The all-diesel combined power plant uses a diesel engine as the main engine, so it is also called a diesel-diesel combined power plant.

On the third day when Zhu Yingjie and others arrived at the Chunfeng Academy of Sciences, they saw this joint power device that represents the world's leading level.

Mr. Nian Haihong rushed over from Jinan to introduce the joint power unit in person, which flattered Zhu Yingjie and his technical team. Mr. Nian Haihong has a very high position in the domestic power field.

"The Quanchai Combined Power Plant is a product jointly produced by our Jichai General Plant and the Chunfeng Academy of Sciences to localize similar products from the German MTU company." Mr. Nian Haihong was full of energy and surrounded the room as neatly sized as a small room.

The Quanchai combined power unit rotated slowly while introducing.

Zhu Yingjie and others followed closely, listening respectfully and attentively.

"Xiao Yao said that the Navy must build a 5,000-ton frigate. The target requires a maximum speed of 30 knots and a maximum range of 7,500 kilometers when cruising at a speed of 16 knots. We do not have a power plant that can meet these targets at the same time."

Nian Haihong said with a smile, "He spent a lot of money to buy a diesel engine with a maximum power of 7,500 horsepower from the German MTU company. We worked with the Chunfeng Academy of Science to make a local copy of it, and then made improvements on this basis."

"The maximum power has been changed to 9,000 horsepower, which is amazing." Zhu Yingjie said with emotion.

This is where Nian Haihong is proud of. Jichai General Plant has high-horsepower marine diesel engines, but many of their performances cannot meet the requirements of military ships and can only be used on civilian ships. However, they have made some efforts to increase the horsepower of MTU diesel engines.

It has made a contribution, which proves the strength of Jichai General Plant, and the improved MTU diesel engine is manufactured by Jichai General Plant. Although its lifespan is only two-thirds of the original one, other performance has been improved.

The service life is mainly related to raw materials. I am afraid that this problem will need to wait until the special steel branch of the steel plant on the east coast industrial island is built, and wait until the relevant projects of the Basic Materials Research Institute and the Process Technology Research Institute of the Chunfeng Academy of Sciences make breakthroughs before it can be completely solved.

"Xiao Yao told me, and I think what he said makes sense. People who are not worried about the immediate future must have long-term concerns. It is always good to take a long-term view. A ship will be put into the water for as short as twenty or thirty years, and as long as four or five years.

In ten years, leaving enough redundancy also leaves enough potential for modification and improvement in the future." From a more practical perspective, Nian Haihong expressed his support for Yao Yuan's "5 protection and 8 drive" proposal, that is, designing and building a 5,000-ton

Frigate, 8,000-ton destroyer proposition.

Zhu Yingjie said in a deep voice, "Sister, the all-diesel combined power plant is obviously a power system prepared for 5,000-ton frigates, and the CFZR-30 gas turbine power system is a power system prepared for 8,000-ton and tens of thousands-ton large drives.

This guy Xiao Yao has been preparing for it a few years ago."

"Slowly you will realize that many of his ideas are very advanced and are often verified by real developments." Nian Haihong looked over at Yao Yuan who was talking to the power experts from the 703 Institute who had just arrived today, and sighed softly.

He said, "The Neptune gave him too much stimulation. Stop playing around. You are a passionate young man with technology and funds. He is going to be very aggressive."

Shaking her head, Nian Haihong said, "He has never suffered such humiliation."

Zhu Yingjie nodded solemnly, "The Sea King incident is not only his humiliation, but also the humiliation of our Chinese nation. We will build a strong People's Navy without hesitation, and we will not hesitate to do anything. Elderly, you are highly respected, I will say more at the expert seminar."

Sentence, the boss will pay more attention to it."

Nian Haihong said, "I will definitely give it a good lecture. Not only will I do it myself, but I will also bring Xiao Yao's mentor Professor Mo and my old friends to do it together."

He looked at Zhu Yingjie and said, "But, Xiao Zhu, we old guys have retreated so badly, and most of them are not in the military industry system, no one knows the weight of what we say. The key is still up to you. It depends on you."

these people."

"Yesterday I made a statement and fully supported it, and so did Xiao Zhong." Zhu Yingjie said.

"This way, the chance of success is at least 50%." Nian Haihong said with a smile.

After a slight hesitation, Zhu Yingjie took a few steps to the side, and Nian Haihong followed him tacitly. At this time, Zhu Yingjie whispered, "Old man, there are some things I can't say to Xiao Yao. Before you came, I still

I’m worried.”

Nian Haihong pondered for a moment and asked, "Is there a lot of resistance?"

Zhu Yingjie nodded, "There are still disputes within the army about which direction the navy should develop. The submarine faction, the aircraft carrier faction, the defensive faction, and the offensive faction are very complicated. Changing a five-thousand-ton destroyer into a frigate, starting from our design

It is not difficult in terms of blocks, but it means that the nature has changed, and it means that the development direction needs to be determined, which is a very difficult job."

He looked back and said, "Xiao Zhong left early this morning, and he will have to work on this matter next. The things on his side are the most difficult to do."

Sighing lightly, Zhu Yingjie said, "Our opinions are only reference opinions after all. It is the troops themselves who make the decision. In fact, there has been a debate within the military on the continued construction and renovation of the Varyag. It is already very difficult to achieve the current situation.

Already."

Nian Haihong understood and said to the point, "They are all caused by poverty."

This is the source of the problem.

In fact, everyone knows that the Chinese Navy and other military services will one day develop into an armed force that can compete with the US military, or even surpass it.

But based on reality, there will be debates about which area to develop first.

The so-called submarine faction, aircraft carrier faction, defensive faction, and offensive faction. In the final analysis, whether to develop submarines or aircraft carriers first, whether to strive to develop offshore defense capabilities or to develop preliminary far-sea offensive capabilities is a matter of priority.

The reason is just two words - no money.

If there were enough funds, there wouldn't be so many debates. Let's do it all!

"It is already very difficult to build two 5,000-ton destroyers." Zhu Yingjie sighed and said that the helplessness involved cannot be understood except by personal experience.

Nian Haihong said, "You want me to vaccinate Xiao Yao in advance. If it fails, it will be easier for him to accept it."

"I hope he can understand, but there is one thing that we will definitely support fully," Zhu Yingjie said.

"Well, do your best," Nian Haihong said.

After all, Yao Yuan is a young man. His optimism and confidence come from his achievements and the wealth he controls. It is inevitable that he will consider the problem first. Or, he has already considered the outcome and has done a good job in psychological construction.

"The more I go on, the more I realize that all policies centered on economic construction are correct. Develop the economy first and then talk about other things. If the economy is not developed, talking about anything else will be rootless. I remember that Xiao Yao purchased the Jichai General Factory

Later, he said at the workers' meeting that the first thing Jichai General Plant needs to do is to divest all non-production assets. Only when the production aspect is taken up can there be a basis for talking about other services. The same is true for a country. Someone needs to do it.

Out of hope."

Nian Haihong said in a deep voice, "The person Xiao Yao is unwilling to make sacrifices for is the army, so he has spared no effort to do this job over the years. If he fails, it will definitely hit him hard. This, that

Director Zhong should understand."

"I think he understands." Zhu Yingjie nodded in agreement.

Smiling, Nian Haihong said, "We should be more optimistic. There was nothing before, but now it is different. We have cfzr-30 gas turbines, a comprehensive electronic system for the ship "Light", an all-diesel combined power plant, and a ship power management system.

, hold the seminar well and fully explain the significance of the four major system technologies, and the superiors will pay attention to it."

"Xiao Zhong also had the same opinion, so the seminar was postponed for five days. He ran around to make contacts, invited more heavyweight experts, and made the specifications as high as possible and the larger the scale, the better." Zhu Yingjie said.

Nian Haihong waved her hand gently, "Let the young man be busy, I will take you to see the ship that uses the all-diesel combined power unit. I just happened to return to the port of Lingang Industrial Park today."

"Has it been shipped?" Zhu Yingjie was shocked.

"It's been more than half a year. Now it's time to do an inspection to see how the test is going." Nian Haihong and Zhu Yingjie walked out, followed closely by the others.

The administrative personnel of the Chunfeng Academy of Sciences and the concierge of the Chunfeng Group who were responsible for protecting them immediately arranged vehicles, and the vast convoy headed towards Lingang Industrial Park.
