Super Craftsman

“Why is it easy?” Zhao sighed with a sigh, then suddenly thought of something, turned his head directly, and asked Guo Tailai: “Do you have a solution?”

"The noise that the submarine can produce is nothing more than the hydrodynamic noise generated by the shape of the ship; the active noise generated by the rotation of the propeller; the position and design size of the drain hole will also generate noise; the most critical is the engine, transmission, etc. The shaft running device will produce noise." Guo Tailai thought for a moment and replied slowly: "The targeted design modification!"

"It's very difficult." Zhao Wei shook his head, and she didn't know why, but it was too difficult to achieve. "

I don't have any good advice on the shape. I am not very familiar with fluid mechanics. Guo Tailai replied with enthusiasm: "But the improvement of materials and some craftsmanship should be able to reduce some?" ""

In general, if you can reduce the noise by 6 decibels, the detection distance of the enemy's passive sonar will be reduced by 50%! "Zhao Wei agrees with this: "If you use the processing precision of your level, it can really reduce a lot. ”

"When I think about the material, I should be able to find some suitable materials for the anechoic tile. If possible, I can absorb some radar waves." Guo Tailai thought for a moment: "Let's pay attention to some special joints and isolate some of the pipes along the pipeline." Vibration noise should be reduced?"

But the noise is still the engine and the drive shaft and the propeller! "Zhao Wei knows the meaning of Guo Tailai. Although it can be reduced a little, the place with the largest proportion is not solved. The noise of other parts is not enough to reduce the overall noise of the submarine."

“The propeller is noisy.” Guo Tailai indulged for a while and said slowly: “Either referring to the latest propeller design of the United States and Lao Maozi, we now have large-format five-axis CNC, and can also produce high-precision curved propellers. If the size is not enough If you can, I can do it even more. Recently, I have improved it. I should be able to achieve higher precision. The area can be several times larger."

"Really?" Zhao Yu was overjoyed and lifted up from Guo Tailai's chest. He was very surprised to see Guo Tailai. "

Really. Guo Tailai nodded, but then remembered something general: "The workpiece is too large, and it seems that there is no need for high precision." ”

Zhao Wei also smiled and put his face on Guo Tailai's chest again. Guo Tai is right, the big ones are different from the precision ones. They can't move more than a few meters. The size of the temperature can change the temperature of hundreds of times the precision required by some precision workpieces. Change, it is enough to support a few filaments, no need to be more precise. And in general, the working environment of large workpieces is unlikely to be constant temperature.

“What else?” Zhao Wei continued to ask.

"The future is definitely the world of magnetic fluid propulsion." Guo Tailai said with certainty: "Last year was the year before, did we not have successfully developed a magnetic fluid propeller?"

“The head and power are too small.” Zhao Wei shook his head slightly: “Up to one ton of hull, the speed is still less than one meter per second. It is still in the experimental stage, far from the actual application. And it needs a large generator. The battery also needs a revolutionary upgrade."

"Or learn the single-axis jet propeller of the American Seawolf-class nuclear submarine." Guo Tailai said subconsciously, but immediately denied it: "Well, behind, their latest one should be a single-axis single-blade pump propeller, we You can also do it!"

Zhao Wei has once again looked up and smiled and looked at Guo Tailai, his face full of pride. Switching to other people, this time may ask Guo Tailai how to know so detailed, the seawolf-class nuclear submarine is some early, knowing that it is not strange, the latest US-type Virginia-class nuclear submarine propeller information, how did he know? But Zhao Wei did not ask at all, the fat man knows something, need to explain to others so detailed?

“Single-axis single-blade is not optimal.” Guo Tailai thought about it: “We can try to push the shaftless pump and save the drive shaft directly. Naturally, there is no noise from the drive shaft. If the engine uses a motor. If you can, you can be very quiet. At that time, the conventional submarine can do less than the ocean background noise."

"What if a nuclear submarine?" Zhao Wei asked.

“The reactor certainly can't be stopped at any time.” Guo Tailai quickly replied: “Look at the efficiency of the anechoic tile and soundproofing materials and the application of other noise-reduction designs. You can try it, maybe it can be equal to the ocean background noise.”

Zhao Wei took a kiss on Guo Tailai’s face and then got up directly. The noise of the nuclear submarine and the noise of the ocean background are flat, which means that it will hardly be easily found. This is a real weapon of the country. Zhao Wei has to report it anyway. to

It is said that Guo Tai’s ideas can be realized. Zhao Wei never doubts that the fat man has never let her down. How to achieve it, she only needs to know that this is enough to quickly catch up with the US advanced Russian submarine.

Didn't he say that his fat man is going to study silencer materials? If it is a research report, it may be necessary for Zhao Wei to verify it, find an expert to prove it, and then meet with the leaders of the final assembly for a long time. If the fat man can say it, Zhao Yilian does not even think about it, it must be a relatively large grasp. This

On the other hand, Guo Tailai has a natural advantage. He does not need state funding, and then sells it to the country after the results are achieved. This allows private companies to take a large part of the decision-making risk, which is actually more cost-effective than national research. Because Guo Tailai doesn't care about academic disputes, he doesn't have to argue which genre is the correct mistake. He is the boss, he can do it if he wants to do it, but the state investment is not the case. There are too many things to consider, whether it is capital utilization or efficiency. There is no way to compare with Guo Tailai's private company.

The flexible system and the incentive system that thoroughly mobilizes the enthusiasm of researchers make the efficiency of the Justice Square technology intimidating. The aircraft carrier deck steel that was previously invested by the fat man has been successfully researched in just half a year, and the strength is completely in line with the requirements. The process is now being studied. This is unimaginable in the national research institutes. Unfortunately, only Guo Tailai can do it. anti-

Yes, now Zhao Wei or the final assembly is full of trust in Guo Tailai and Justice Square Technology. As long as they intend to invest in development, there is almost no research and development.

"I knew that General Li would have heard it when he was there." Zhao couldn’t help but complain about Guo Tailai: "If he knows that he must be happy and dead."

Isn't this an idea? Guo Tailai laughed. "When I really have something to talk to, isn't it more exciting?" ”
