As soon as these words came out, Huang Jianguo and Peng Jun looked at Dong Yimin in some surprise, wondering why their chief of staff suddenly made such a decision.

As for why Dong Yimin naturally knew in his heart that the engine silencer was a new thing applied to diesel-electric submarines in the 50s in the Soviet Union, aiming to reduce submarine noise and increase its concealment and penetration.

Since the Soviet Union had just entered the experimental stage at that time and had not yet finalized the form, it was not included in the list of aid to China, but this does not mean that this noise-reducing device is not easy to use.

Therefore, Dong Yimin clearly remembers that Soviet experts once said that the overall noise of the Soviet 641 submarine (foxtrot class) with the addition of diesel engine intake and exhaust mufflers was 8% lower than that when it was not installed.

Don't underestimate the 8% noise reduction, in the vast ocean, this 8% means that the chance of being detected by the enemy will be reduced at a geometric rate, and on the contrary, your attack strength and success rate will be multiplied.

Of course, he naturally won't talk about these things to Huang Jianguo and Peng Jun, firstly, the two may not be able to understand, and secondly, if someone asks why you didn't say it earlier, he can't tell people what happened more than 20 years ago, and he will return it to the Soviet experts almost early.

No matter how you say that you are also a senior leading cadre of the N fleet, you still have to be a little embarrassed.

So Dong Yimin didn't explain or talk nonsense, and directly ordered Huang Jianguo and Peng Jun to go with him to Endeavor Factory for research and research the day after tomorrow.

……

"Chief of Staff, this is the marine propeller production workshop that our factory has just established, here is the cattle head planer, the one over there is the leaf processing lathe, and here, but the treasure of our factory, the original Soviet photoelectric profiling machine tool, can finish the propeller blade. ”

Two days later, Dong Yimin led Huang Jianguo and Peng Jun and other six officers of the N fleet to form a research team, and suddenly came to the Endeavor Factory.

As a result, it turned out that Dong Yimin and others had no intention of going to the factory at all, but directly asked to go to the production workshop to see, if it had been placed a few months ago, Jiao Dalin would have felt a little embarrassed, because the little belongings of the Endeavor Factory were too shabby.

But now, Endeavor has already changed the gun through the equipment retrieved from the excellent factory, so Dong Yimin is not afraid of people to see, but he wants people to go to the processing workshop more, you must know that this is also a manifestation of the strength of the factory.

As for the effect, of course, it is surprisingly good, Jiao Dalin doesn't need to bother with lip color, just point to a few pieces of equipment and introduce it a little, the majestic atmosphere with a sense of industry has already shocked Dong Yimin and others.

"All Soviet originals?"

Looking at the Russian sign on the device, Dong Yimin asked Jiao Dalin beside him in some surprise.

"Yes, all of them are the equipment that the Soviet Union helped us in those years, the base of the equipment has been stored for nearly 20 years, and the stability is better than that of the new machine tools, and the machining accuracy of these machine tools is very good, if it were not for the transformation of the brother factory to other industries, we would not have obtained such good equipment. ”

Jiao Dalin still had a bit of morality on his lips, and he didn't say that these equipment were all thrown to Endeavor Factory as scrap products from the excellent factory, but he said it ambiguously and stayed in a hurry.

However, Dong Yimin obviously had a careful understanding of Endeavor before coming to the factory, and nodded meaningfully when he looked at the equipment in front of him: "It's all good equipment, it's better to stay, otherwise it's not good to be poked in the back." ”

No one answered this, and Dong Yimin naturally knew how to measure it, so he didn't wait for others to interface, so he changed his words and continued to ask: "How is your factory's mastery of this batch of equipment now?"

"We have set up a propeller production team to specialize in the operation and processing of these equipment, and after a few months, most of the team members are proficient in operating these equipment. Jiao Dalin replied proudly.

However, before Jiao Dalin could be happy, Dong Yimin pointed to the three freshly processed propellers not far away, frowned and asked, "Are all the small clovers you produce?"

Jiao Dalin looked in the direction of Dong Yimin's finger, and found that there were three small three-bladed propellers with a diameter of only fifty or sixty centimeters not far away, and he was immediately relieved, so he quickly explained: "That is a propeller processed for fishing boats, in fact, our factory can produce larger and heavier four-bladed propellers." ”

"What are the specific specifications and processing technology? Also, I see that your factory does not even have a standard drawing room, how do you determine the parameters and drawing specifications of the propeller?"

As soon as the confident Jiao Dalin heard Dong Yimin's words, he was immediately stunned, he never expected Chief of Staff Dong to ask such a professional and profound question, and originally wanted to behave well in front of his old instructor, but this is good, and he directly got rid of the chain.

Fortunately, Jiao Dalin is very self-aware, and his face is thick enough, just a little embarrassment, and he returned to normal in a blink of an eye, and immediately pulled Meng Jianye from the crowd, and swore to Dong Yimin: "This is Comrade Meng Jianye, the assistant director of our factory, he is now in charge of the technical work of our factory, and let him answer your question just now." ”

Meng Jianye really wants to say that you are a big-headed ghost, you are a scorched old man, everything that is easy is taken up by you, and when you encounter difficulties, you will push yourself out, it is very bad!

But slander is slander, how to do it, who makes the director of the factory.

"Oh, Meng Jianye, I remember you! In the exercise in the middle of last year, was it just a tugboat that made a beautiful sharp turn in the harbor?"

When it comes to last year's exercise, Dong Yimin is still deeply impressed, especially the turn in the port that is still fresh in his memory, which not only evokes the memories of his youth, but also allows him to score the only excellent score.

Afterwards, he also inquired about the commander who drove the tugboat, and after understanding the situation, he was also embarrassed, so he could only press the impulse in his heart, but he didn't expect to see the person concerned today, so he naturally had to mention it.

Meng Jianye naturally modestly said that he was just an axe, and then a few sycophants who did not make a trace slapped it lightly, which made Dong Yimin laugh more than once.

However, Meng Jianye's little tricks are really not enough in Dong Yimin's eyes, praise is praise, laughter is laughter, but the question still has to be answered.

Meng Jianye saw that he couldn't get mixed up, so he could only breathe a sigh of relief and slowly speak: "In fact, our preliminary work on the ship is a cooperation model between enterprises and schools, which means that the factory is not responsible for specific design and drawing, but is completed by the cooperative school!"
