Chapter 854 Normal hanging hair

For the purpose of confidentiality and preventing sabotage by enemy spies, the military and civilian businesses of the Hudong Factory were physically separated. In addition, Lin Qing was from the 701 Institute after all, so he had only heard of the LNG ship project.

As for the specific technical details such as Gas-Transport liquid cargo tank and boil-off gas reliquefaction system, I had no idea about them at all.

Therefore, when he first heard the straightforward name "condition monitoring and fault automatic diagnosis system", he immediately became excited:

"In order to meet maintenance needs, we specially left some space margin for the power compartment during the design. If sensors are needed..."

Obviously, this feature is very useful for the new frigates at hand.

However, Chang Haonan waved his hand:

"The sensor is definitely not installed in the power compartment. It won't be able to detect anything. It has to work directly with the power system itself."

"With the power system itself..."

Lin Qing's face froze after hearing this:

"Does this mean that we need to dismantle these two gas turbines and rebuild them?"

Now the ship sections are almost completely assembled. If any modifications are made to the equipment within the sections, it will inevitably affect the launching schedule.

This is a significant loss for the first ship of a model, which undertakes a considerable amount of testing tasks.

"Uh... that's not necessary."

Chang Haonan quickly explained:

"After all, the QC130 is based on the WP-14, and the issue of electronic control was taken into consideration during the design, so it can be modified in situ. However, because you do not have a unified power control system for the entire ship, this function cannot be integrated into the bridge or CIC, and can only be viewed in the engine room."

"call--"

This answer made Lin Qing feel relieved:

"That's not a big deal. There will always be someone on duty in the engine room of a warship, and we will mainly use this function during maintenance."

In theory, the power systems of modern ships are directly controlled by the bridge section and can therefore operate unmanned.

However, warships have to take special circumstances into consideration and still need to set up a special engine room duty post.

The only difference is that there is no need to follow commands from the bridge to operate the engine room or even fill coal into the boiler as before.

This is also why a warship of several thousand tons generally has dozens or even hundreds of crew members, while a cargo ship of one hundred thousand tons or even several hundred thousand tons may only have twenty or thirty people.

It was not until this time that Lei Zhixing, who was first questioned by Chang Haonan, interrupted:

"Mr. Chang, there is no problem from the perspective of system hardware, but we have never done parameter calibration of gas turbines before, so if we want to realize the complete functions, we may have to cooperate with the turbine design unit and the shipyard."

Before the conversation was over, Lin Qing and the engineer named Liu next to him said almost in unison:

"No problem, we will definitely cooperate on business matters!"

Wu Wentao next to him also expressed his agreement.

Anyway, at the group level, the shipbuilding industry and aviation power have already started cooperating on the LNG ship project, so it doesn't matter if there is another one.

"It's like a close relationship..."

Wu Wentao concluded.

"No... I'm mainly worried about efficiency..."

Chang Haonan sighed:

"This system is still in the development stage. Ordinary employees of Torch Group are not very familiar with it. If only the two of them rely on it, it would be a bit troublesome to run back and forth."

"Um……"

Lei Zhixing and Liu Fangping also nodded slightly.

It’s actually not that difficult to run back and forth physically, after all, they’re both at the Hudong Shipyard and not that far away.

But not everyone can multi-thread their work like Chang Haonan, so working on two similar but different projects at the same time is likely to lead to confusion between the two sides and then chaos together.

"How about... Professor Chang lend us the new doctoral student in our group for two days?"

Liu Fangping, who usually speaks very little, suddenly suggested:

"I have talked to Wang Jie before. Like Lei Zhixing, he also has a background in mechanics. He also studied the fault characteristics of rotary mechanical equipment during his master's degree. However, he had never been exposed to the theoretical concept of high-dimensional data dimensionality reduction before, so he should be able to get started quickly."

"Is this..."

Chang Haonan hesitated:

"I'll ask for his opinion when I get back. We still need to refer to the students' opinions in this area of ​​research."

"If it doesn't work out, I plan to recruit a group of postdocs and researchers in a few months. Anyway, we have the technology, and there is always a solution to the problem of manpower."

"That's fine..."

Lei Zhixing nodded:

"Anyway, shipbuilding is not something that can be achieved in just a few days."

"Then General Lin, you guys should continue to advance the project according to the original schedule. When the warship is outfitted, we will solve the power system problem in parallel with the ship's surface operations?"

Chang Haonan looked at Lin Qing beside him.

"can."

Since it will not affect the progress of the project itself, the latter naturally has no objection.

……

After visiting the construction of the entire ship, considering that it was still early, Wu Wentao and Lin Qing took Chang Haonan to the equipment warehouse to take a look at the 3K95 ship-to-air missile system that had been delivered.

That is Doyle from Haiji.

However, the appearance of this set of things is somewhat different from what Chang Haonan remembered...

"I remember..."

Chang Haonan looked up at the four launch boxes in front of him and asked in surprise:

"The launcher of this 3K95 should have 8 rounds arranged in a cylindrical shape, right?"

“Yes, that’s the original version.”

Lin Qing nodded:

"Eight rounds, similar to a revolver cylinder, but with only one firing port and a rotating mechanism underneath."

"But we can't understand why we have to use this strange launch method. It doesn't save space or cost, and it increases the complexity of the system out of thin air."

Just after I finished complaining, Engineer Liu next to me added:

"Moreover, the land-based 9K330 actually already has a set of mature 8-tube launch boxes, but even so, the Soviets still designed... such a thing for their navy."

In fact, Chang Haonan had heard of relevant analysis a long time ago, and believed that the reason for this peculiar design idea was that the Soviet-style sea-based vertical launch, whether 3K95 or the long-range S300F, were direct replacements for the single/double-arm launchers of earlier years.

This is equivalent to hiding the launch pad directly under the deck to prevent high sea conditions from having adverse effects on the missile and launch system.

With this in mind, it is almost a natural idea for 8 rounds to share one launch port.

The 9K90 single-arm launcher on the Sovremenny class has one firing position for every 24 rounds of spare ammunition.

But later people had already seen the drooping hair of the Aegis, so looking back, they of course thought everything about it was strange.

"So you just got four sets of Land-Based Doyle vertical launch systems?"

Chang Haonan looked at the four rectangular metal boxes and found that they did look a bit similar to the one in 9K330.

"Not directly from the Army."

Lin Qing explained:

"In fact, the Russians themselves also thought that the rotary launch mechanism was very strange, so they had designed this 8-mounted vertical launch a long time ago, but later they did not launch new ships, so there was no place to install it."

"After we learned about this situation, we packed this equipment back along with several battalions' 9K330s and some related technical data..."

"Even if the Type 054 is replaced with a larger domestic vertical launch system that can launch medium-range or even long-range missiles, this relatively small close-in defense system will definitely have its place."
