Chapter 70 The timing is very good
Kuang Wei smiled enthusiastically and pulled a chair and sat down, "Director Yang, you're very busy lately."
"Yeah." Yang Fan nodded gently, got up and brewed a cup of tea for Kuang Wei while holding the boiling water bottle, and said, "I have always been very busy. Since our 052 ship entered the comprehensive design stage, everyone is almost the same."
"Yes, it's almost the same." Kuang Wei took the cup of hot tea and said with emotion, "In addition to being busy, the pressure is also very high. The technical difficulty of the 052 ship is several times that of the 051 ship. Brother, I can hardly sleep at night now, and the pressure is really too great."
Yang Fan looked at Kuang Wei carefully and found that he was really under great pressure and didn't seem to be telling lies.
He comforted: "Only when there is pressure, there is motivation. The design of the 052 ship is indeed quite difficult, but with the technical accumulation of the 051 ship, it will take several years to succeed in the end."
"I don't doubt the final success. After all, it's the whole country's strength. But at present, our overall design has also begun to enter the comprehensive design stage. As the design unfolds, I have discovered many problems, the biggest problem is the insufficient cabin capacity."
The 052 ship's designed displacement is only about 4,200 tons and the full load displacement is about 4,800 tons. It is easy to imagine how difficult it is to plug tens of thousands of equipment into the hull with a displacement of more than 4,000 tons.
As a ship design expert, Yang Fan understood Kuang Wei's current difficulties and nodded: "The difficulty is indeed much greater than that of the 051 ship."
"well......"
Kuang Wei sighed softly, "So many equipment and the cabin capacity are so small, we can only compete for millimeters, and each millimeter is calculated very accurately."
This is called careful design, one success.
In the era without computer drawing, if you have to draw a picture again due to calculation errors, then all the design drawings you have worked hard to draw will be scrapped and everything will be pushed back and will be over again, and the workload will be extraordinary.
One of the reasons why Kuang Wei was under great pressure was that he was worried that such a thing would happen. If he wanted to start over, his previous efforts would be in vain.
If the cabin capacity is small and there are many equipment, if the size calculation in some place is incorrect and the equipment cannot be placed, this situation is very likely to occur and can only be redesigned.
If the cabin capacity is abundant and there is less equipment, it will be much easier to do. Even if the size calculation is incorrect, as long as it is not particularly outrageous, you generally don’t need to start over again, because there is plenty of room for you to modify.
Kuang Wei shook his head with a bitter smile, his face full of bitterness.
Yang Fan asked with concern: "Director Kuang, where is your design work going?"
Kuang Wei said: "The size calculations of some main cabins have been started, and the overall design plan has been successfully passed and reported to the 052 ship general command center."
That's it...
Yang Fan seemed to be thinking. To be honest, it was a very good time at present. To put it more than anything, if you miss this village, you will never have this store again.
No one knows the many shortcomings of the 052 ship at the beginning of its design, the most typical of which is the overall design of the hull. The lack of redundancy has led to many equipment on the ship being unable to be upgraded and replaced, because the upgraded equipment may no longer be installed into the limited hull.
Later, there was no choice but to undergo major changes to the hull and undergo major surgery, which not only took a lot of time, but also consumed a lot of manpower and material resources.
Such major changes not only increase the design workload of designers, but also because the design changes are too large, many of the original molds and toolings during the construction process can no longer be used, causing huge waste.
This is indeed a good opportunity now.
Yang Fan previously mentioned that the design of the 052 ship must be platform-based, with redundancy fully considered to facilitate future upgrades and improvements. Obviously, some comrades did not adopt Yang Fan's suggestions when making the overall design plan, and still came up with such a design plan as in history.
If the 052 ship enters the meticulous design stage, if it is overturned and made major changes at that time, the efforts of so many designers will be in vain, and all the design drawings drawn before may be invalid.
But Yang Fan was a little hesitant, and he allowed the 052 ship to develop according to the historical trajectory, but to adjust the direction and reduce detours?
After pondering for a little while, Yang Fan still felt that he would understand the situation in detail first, so he asked, "Director Kuang, I also came out of the overall designer and am more interested in the overall design, especially the design of the hull of the 052 ship."
Kuang Wei glanced at Yang Fan with a little surprise, but he didn't take it too much and said truthfully: "We have started some size calculations of the main cabin of the hull. The general diagram of the hull design should be available in one or two months."
"Although the formal general map has not been released, many things are already clear, such as the main size of the hull, standard displacement, etc.."
"Oh." Yang Fan seemed to be intrigued and waved: "Let's go to your office and let's have a good chat, how about it."
Kuang Wei didn't even think about it. He felt very stressed. He finally had a partner to talk to, so he would not let it go. He immediately agreed and said, "Okay, let's go now."
But he just wanted to express his feelings. He would never dare to expect any constructive suggestions on the overall design of the 052 ship, nor would he dare to expect Yang Fan to help him.
The two of them left the combat system design room together and entered Kuang Wei's office soon.
Yang Fan came to this office several times, but at that time he was just a newcomer to the overall design room. He was basically a soldier under Kuang Wei. He came here with a nervous, cramped, or looking up mentality. It is different now.
Yang Fan no longer had the same mentality as before, but talked and laughed with Kuang Wei, just like an old friend of many years.
"Director Yang, please sit down."
Kuang Wei was very enthusiastic. While calling Yang Fan to sit down on the sofa, he poured Yang Fan a cup of hot water.
The two sat down and had a good atmosphere and chatted a little. Ru Kuang Wei also introduced some size data and other data that have been basically determined by the 052 ship.
According to their calculations, for example, the tentative size of the 052 ship is 146 meters long, the side width is 16 meters, the draft is 5.1 meters, the standard displacement is 4,200 tons, and the full load displacement is 4,800 tons...
Yang Fan listened carefully.
After listening, Yang Fan said: "The hull general drawing has not yet been released, so the sketch should have come out."
"It's already out, and there are several plans, you can take a look."
After saying that, Kuang Wei took a few drawings from his desk and spread them out, and introduced their design of the hull of the 052 ship to Yang Fan in turn.
From these sketches, we can see that the main dimensions of the hull are basically the same, and the only difference is that there are subtle differences in some cabins.
Yang Fan's eyes fell on the power cabin. The plan for the 052 ship to use the diesel-Ranking combined power has been decided, powered by two LM2500 gas turbines and two Mtu-20 v956 tb92 diesel engines. This plan will hardly be changed.
Obviously, Kuang Wei and the others knew that this power plan would not be changed, so they almost tailored the power cabin, which could just put down two lm2500 gas turbines and two mtu-20 v956 tb92 diesel engines, and there was no extra space.
Tailored, just right.
There is no extra cabin capacity!
Yang Fan's brows frowned slightly. These sketches were exactly the same. Almost all the power cabins were like this. If there were no accidents, the power cabins would be the same in the future official overall picture.
This won't work!
Yang Fan pondered in his heart and thought, should he mention it?
If Yang Fan is the deputy director of the overall design office, he would definitely raise this question clearly. The power cabin is not built with energy, but should leave enough margin and space. In the future, if the lm2500 gas turbine is discontinued, and when we choose other models of gas turbines, the newly selected alternative gas turbine can be placed in the power cabin.
The power tank is designed too small, and the new alternative gas turbine cannot be placed in the power tank, which means that the several 052 ships built in the early stage can only use the lm2500 gas turbine as power. Once the lm2500 gas turbine is faulty and needs to be replaced, it will be troublesome.
Unfortunately, Yang Fan is not the deputy director of the overall design room, but the deputy director of the combat system design room. If you clearly express different opinions on the design of the hull, there is a suspicion of having a rat and meddling in other people's business. Some people may even laugh at Yang Fan for being too wide and stretching his hands too far.
But even though she knew there was something wrong and let it go, Yang Fan felt a little unwilling to accept it, so even a tangled look appeared on his face.
Do it, or don't care?
