With the submarine in front and the rescue ship behind, the two boats slowly left the trestle and entered the bay. m.

It is only the first sea trial, and it is not necessary to enter the real sea for the time being.

The public bay where Sanyou is underwater is originally a natural harbor, and the water depth can fully meet the needs of submarine sea trials.

Several fishing boats that were originally fishing in Gongwan have been persuaded to leave this sea area early, and originally this sea area of Gongwan belonged to Kawashima Ship Repair, and Sanyou still has the jurisdiction of this sea area after taking over underwater, but Sanyou underwater does not prohibit fishermen from entering this sea area to fish.

Sanyou underwater non-military facilities, good neighbors.

The two boats sailed to the middle of Gongwan one after the other, and Qin Feng's voice came from the walkie-talkie: "Dongyi, the water depth here is 126.5 meters, and the underwater terrain is flat, so you can conduct sea trials here." ”

Qin Long replied, waved his hand at the rescue boat behind him, turned around and nodded at Lin Huan: "Let's dive." ”

Lin Huan and Qin Long got back into the submarine one after another, and as the double-sealed hatch was closed, the submarine slowly entered the state of diving, and soon disappeared completely on the surface of the sea.

The crew in the submarine began to nervously carry out various tests, 5 meters, 10 meters, 20 meters......

Andre smiled at Qin Long and said: "Chinese Dragon, you can amplify your courage a little more, this submarine can dive to a depth of 200 meters." ”

Qin Long said with a smile: "It's better to implement it according to the original plan, step by step, and find that the problem can be solved in time." ”

Qin Long was relaxed on the surface, but in fact, since the submarine went to sea, he had completely let go of his subtle realm, and every slight change inside and outside the submarine was under his control.

An accident involving a submarine underwater is a major accident, and there are very few examples of successful escapes, especially in the deep sea.

Type 021 submarine today's sea trial plan only dives to a depth of 30 meters, this depth is exactly the dividing line where sunlight penetrates the seawater, at this depth Qin Long has full confidence to ensure the personal safety of the personnel in the submarine, even if the submarine loses the power to float, Qin Long only needs to give an order, and those shrimp soldiers and crab generals can lift the submarine out of the water even if they lift it.

Otherwise, Qin Long would not agree to Pork Rong taking Qin Jie into the submarine as well.

Of course, even if Qin Long was sure to ensure the safety of everyone in the submarine, he also hoped that this sea trial could be successfully completed, after all, this was the first submarine that Sanyou had completed underwater.

More than an hour later, the Type 021 submarine completed all the sea trials originally scheduled for this sea trial and returned to the dock, and the workers happily beat gongs and drums to celebrate the success of the Type 021 submarine sea trial.

Although Qin Long had a smile on his face, he was not so happy in his heart.

There were no major problems in this sea trial submarine, but many minor problems were discovered, especially the relatively large defects in the submarine's balance control system, but this defect has not yet been noticed.

Qin Long did not believe that such a defect would exist on the Severodvinsk-class submarines, which was not too problematic in normal navigation, but fatal in an emergency.

It seems that we have to talk to Andrey to see if this flaw is originally a flaw in the Severodvinsk class itself, or if this old Russian man cut corners in the design and construction of this submarine.

Pork Rong pulled Qin Jie to say goodbye to Qin Long, Daqin Pictures' first film "The Social King" was completed and entered post-production, and Qin Jie wanted to rush back to preside over the film distribution.

Qin Long laughed and teased Qin Jie: "Xiaojie, you are not qualified as the general manager, I have to criticize you, professional things should be done by professional people, it is not necessarily a good thing to do things in person, sometimes rest is also work." ”

Qin Jie looked at Qin Long and said with a smile: "Chairman, you have done a very good job in this regard, sometimes our directors even forget that Daqin Industry still has you, the chairman." ”

Qin Long's face was entangled: "I just want you to rest for a few more days, is it interesting to squeeze me like this?"

"Interesting. Qin Jie giggled and pulled Pork Rong and ran away.

Qin Long shook his head with a smile, walked up to Andre and Lin Huan, who were talking, and bluntly said to Andre who was talking: "Lao An, I think the design of this submarine's balance control system is a little unreasonable. ”

Andre sighed, looking at Qin Long, the head soldier of the submarine, with some surprise, he didn't expect Qin Long to be able to pick out the flaws in the design.

Even Lin Huan didn't see it, can you see it?

Lin Huan opened the design diagram in confusion and leaned in front of Qin Long and asked, "What do you say that the design of the place is unreasonable?"

Many design flaws cannot be detected without sea trials, and even if some invisible defects are still difficult to detect.

Qin Long was already familiar with the design drawings of the Type 021 submarine, and he also didn't notice any problems before this sea trial, but as soon as the submarine entered the water, many problems were exposed in his subtle realm.

Qin Long took the design drawings, reached out and took out a 2B from Lin Huan's pocket, and just like that, he held the folder and sketched the balance control system in the design drawing with a pencil and said: "Our design is like this, if we encounter such a situation, it will be like this, if we change the design to this, the submarine will be like this again, let's do this and then and then we can solve this problem, do you understand?"

Lin Huan was stunned when he heard this: "Yes, it should be like this first and then like this, Lao An, do you think it should be like this?"

Andrei stared suspiciously at Qin Long, who was talking, he now had every reason to suspect that Qin Long had seen the design drawings of the Severodvinsk-class submarine, and even spent a long time on the Severodvinsk-class nuclear submarine.

Now the Type 021 submarine imitated by Sanyou underwater is the first draft of the design of the Severodvinsk-class nuclear submarine, because the imitation of the Type 021 submarine is a conventionally powered submarine, the design of the interior of the cabin has been greatly changed, including some core structures have also made some changes, and now the sketch of the balance control system outlined by Qin Long is infinitely close to the prototype of the Severodvinsk-class nuclear submarine, how can this not surprise Andrei?

Qin Long saw that Andre's expression was already clear to him, he smiled slightly and stuffed the design diagram in his hand into Andrei's hand: "Lao An, Director Lin, you study whether this design is feasible, you are experts in technical matters, I am talking nonsense." ”

Lin Huan grabbed Qin Long: "Don't go, let's study together." ”

Qin Long smiled and said, "Okay, but I have to wait until I come back after finishing my business, I think there are still some details of our submarine that need to be modified, and we will discuss it together when the time comes." ”

Looking at Qin Long's departing back, Andre couldn't help but muttered softly: "He's really a devil." ”

The corners of Qin Long's mouth, who had already walked out of the dock, couldn't help but smile.

Am I the devil?

Perhaps.

But Lao An, you have been exposed, you have known from the beginning that this design has such flaws, it seems that I really need to take the time to talk to you properly, otherwise you will think that the high salary I offered you is too easy to earn.

There's nothing wrong with being patriotic, but what you're getting now is the salary I gave you, and at least your work should be worthy of your salary.
