Nie Shiyu started school early, but today is Sunday. After finishing her homework at home, she ran to the shipyard to play. She happened to hear that military representatives were coming, so she came over to take a look. She happened to hear Qin Tao saying that he wanted to invite the general representatives.
Of course I am very happy to come home.
While she was talking, she ran in and saw Zhao Ling standing inside wearing a military uniform.
"Wow, brother, this sister is so beautiful, much prettier than the sister last time!"
"What are you talking about?" Qin Tao's heart skipped a beat.
"Which sister was it last time?" Zhao Ling had a smile on her face.
"Sister Cong Ju, you are here to work as a welding consultant. You originally said you would come here after the New Year. Who would have thought that I have never seen you again. This sister, the room you live in is the room where Sister Cong Ju originally lived."
Nie Shiyu behaved very well, because the last time she faced Qin Tao and Cong Ju, she did not perform well enough and ended up making a big mistake. From that incident, she learned lessons and she must not give anything to Brother Tao.
Shameful.
"Sister Cong Ju?"
"He's a master craftsman from a shipyard. He's in his thirties, and his kids are old enough to do it." Qin Tao quickly explained.
Zhao Ling glanced at him, feeling a little happy. Why did she explain this to herself? It meant that he was afraid that he would misunderstand, and that in his heart, he still had status.
Is it because of his special status that he has an inferiority complex and doesn't come to see me? If that's the case, then forgive him.
"Have you settled in? Hey, why is there an extra little sister?" At this time, Meng Fansheng and Guo Wei came out.
"Well, hello, uncles." Nie Shiyu said very politely, "I'm here to see my brother."
"Qin Gong, it turns out she is your sister."
"Yeah. By the way, you just arrived today. I'll take you out to have a nice meal and give you a refreshment."
"No, there's no need to make special arrangements for us, just the canteen." Meng Fansheng quickly refused.
The military representatives have a special status. If they are bribed by the sugar-coated bullets in the factory and lower their standards, something will happen. Before coming, the three of them all accepted the leadership's teachings not to make mistakes in this regard.
"Okay, then let the cafeteria cook some dishes for you."
There was a long distance from the dormitory to the cafeteria. Nie Shiyu was bouncing as she walked. Zhao Ling looked at her and always felt a little strange. The appearance of the two brothers and sisters were not similar at all!
Zhao Ling looked at the shipyard again. The hull of the dredger was still being welded. Countless sparks were flying, and countless people were busy. On the river beach further away, two of the three submarines had been dismantled, and countless pieces of steel had been dismantled.
Being loaded onto a truck and transported away.
This is where Qin Tao has lived since he was a child, and she and she are almost completely different worlds! Perhaps, he is embarrassed to contact her because of the big gap, right? Maybe he wants to wait until the shipyard develops.
Only when he has enough status will he look for his own, right?
Zhao Ling looked at Qin Tao's back again, and the dissatisfaction caused by Qin Tao's lack of contact completely disappeared.
In the canteen, although the tables were a little shabby, they were wiped clean without any oil stains. Several plates of dishes were put out, including meat and vegetables.
"What do you guys want to drink?" Qin Tao asked with a smile.
His father was on a business trip these days, so Qin Tao took the initiative to take on the task of receiving military representatives. Anyway, Qin Tao was so versatile that it was easy to do such a thing.
"No need, as long as there is water. When the missile boat is delivered, we will have a celebration bar then!" Meng Fansheng said.
"Okay, let's get some bottles of soda, Shiyu, help bring a few bottles over."
"OK."
Nie Shiyu left jumping up and down.
"Shiyu, this name is very good." Zhao Ling looked at Qin Tao: "It sounds much better than your name."
"Yes." Qin Tao nodded in agreement.
"Gong Qin, we have brought over the blueprints of the missile boat. Shall we start construction tomorrow?" Meng Fansheng is a workaholic, so this brought up work matters.
"Of course, our shipyard is large enough. It will be no problem for the first two missile boats to be built simultaneously," Qin Tao said.
A missile boat with several hundred tons is naturally a piece of cake.
"We have seen the design drawings. The overall design is good, but there is one thing." Meng Fansheng continued: "Wrapping the entire superstructure will require covering a large number of steel plates. Will the overall center of gravity increase?
"
Military representatives also have to understand technology. Meng Fansheng's words made Qin Tao admire him very much. He really thought about it seriously.
In the past, there was no such design scheme in China or even in the world. The upper equipment of warships were all exposed to the outside. What was needed was put on it. Although it looked messy, it was nothing.
Now, everything is wrapped inside, which is equivalent to an extra layer of weight on the outside! In this way, compared with the naked body exposed outside, the weight has increased a lot.
"The catamaran that has been launched currently uses ultra-high-strength steel plates. It has been inspected by the customs and the performance of the hull is very good. Therefore, the lower part of the hull remains unchanged, and the part covered by the upper layer is planned to be used
The thinnest steel plate only needs to meet the coverage requirements. Of course, if the Navy requires further reduction of the weight of the upper layer, we can also choose aluminum alloy."
Anyway, the Mingzhou Steel Plant can produce steel plates. Just ask them to roll a batch of thin steel plates. If the Navy is not satisfied, then they can use aluminum alloy.
In fact, the best thing is composite materials. Use composite materials to make warships, which have the best stealth and can absorb part of them after all.
But now, we have just entered the 1990s, and there is not enough research on composite materials in the country. The shipyards are even unable to master the manufacturing technology suitable for the materials, and accidents may occur. Therefore, Qin Tao did not mention it.
.
"Aluminum alloy?" Meng Fansheng said: "This is a good choice, but if aluminum alloy is used as the upper covering, how can it be welded to the hull below?"
In the Falklands naval battle in the 1980s, the British HMS Sherfield caught fire after being hit, burning with black smoke. The scene was extremely spectacular. The fire was eventually unable to be controlled, and damage control had to be abandoned. The reason was later analyzed. Sherfield
In order to reduce weight, the superstructure is made of aluminum alloy materials. One reason is that aluminum alloy burns too easily.
However, the experience at that time was not taken seriously by warship designers. After entering the 1990s, aluminum alloys were still used in the construction of various warships, even big ones like the American Littoral Combat Ship. After all,
Aluminum alloy is the best material they can find to reduce weight.
