Chapter 854 Normal Hanging Hair

For the purpose of keeping secrets and preventing destruction by enemy agents, the military and civilian operations of the Hudong Plant are physically separated. In addition, Lin Qing is from the 701 Institute after all, so he has always been concerned about the LNG ship project. The degree of hearing.

As for the specific technical details of the Gas-Transport cargo tank and the boil-off gas re-liquefaction system, I have no idea at all.

Therefore, when he heard the straightforward name "Condition Monitoring and Automatic Fault Diagnosis System" for the first time, he immediately became energetic:

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

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

However, Chang Haonan waved his hand:

"The sensor is definitely not installed in the power cabin, so it can't detect anything. It has to directly cooperate with the power system itself."

"With the power system itself..."

Lin Qing's expression froze after hearing this:

"Does this mean that these two gas turbines have to be dismantled and modified?"

Now that the ship segments are nearly completely closed, if any further modifications are made to the equipment in the segments, it will inevitably affect the launch schedule.

This is a considerable loss for the first ship of a model that undertakes considerable testing tasks.

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

Chang Haonan quickly explained:

"After all, the QC130 is the basis of the turbojet 14. The electronic control issue was taken into consideration when designing it, 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 It’s inside the CIC and can only be viewed in the engine room.”

"call--"

This reply made Lin Qing relieved:

"It doesn't matter. Anyway, someone must be on duty in the engine room of a warship, and we mainly use this function during the maintenance process."

Theoretically, the power system of modern ships is directly controlled by the bridge part, so it can work unattended.

However, warships must consider special circumstances and set up special engine duty posts.

It's just that there is no need to operate the engine or even fill the boiler with coal according to the commands from the bridge as before.

This is why a warship of several thousand tons usually has dozens or even hundreds of crew members, while a cargo ship of 100,000 tons or even hundreds of thousands of tons may only have 20 or 30 crew members.

It was only then that Lei Zhixing, who was first asked by Chang Haonan, intervened:

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

Before the words could even be finished, Lin Qing and the engineer surnamed Liu next to him expressed their opinions almost in unison:

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

Wu Wentao next to him also agreed.

Anyway, at the group level, the shipbuilding industry and aviation power have already begun cooperation on the LNG ship project, so there is no need to have another one.

"Kiss, kiss, kiss..."

Wu Wentao concluded.

"No...my main concern is efficiency..."

Chang Haonan sighed:

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

"Um……"

Lei Zhixing and Liu Fangping also nodded slightly.

Physically, it's okay to run from both ends. After all, they are both at the Hudong Shipyard, not far away.

But not everyone can handle work with multiple threads like Chang Haonan, so working on two similar but different projects at the same time is likely to cause the two sides to get confused and mess up together.

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

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

"I have talked with Wang Jie before. Like Lei Zhixing, he also has a mechanical background, and he has studied the fault characteristics of rotary mechanical equipment during his master's degree. However, he has never been exposed to the theoretical concept of high-dimensional data dimensionality reduction before, so he should get started. It’s pretty fast.”

"Is this..."

Chang Haonan hesitated for a moment:

"I'll ask for his opinion when I get back. We still have to refer to the students' own opinions in the field of research."

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

"That's fine..."

Lei Zhixing nodded:

"Anyway, the progress of shipbuilding cannot be seen in three days or two."

"Then Mr. Lin, you will continue to advance the project according to the original timetable. When the warship is outfitted, we will solve the problem of the power system simultaneously with the ship's surface operations?"

Chang Haonan looked at Lin Qing next to him.

"Can."

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

…

After visiting the construction status 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 of 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 sets of launch boxes in front of him and asked with surprise:

"This 3K95 launcher should have 8 rounds arranged in a cylindrical shape?"

"Yes, that's the original version."

Lin Qing nodded:

"Eight rounds of ammunition, similar to the magazine of a revolver, but there is only one firing port and a rotating mechanism below."

"But we can't understand why we need to use this strange launch method. It neither saves space nor cost, and it also increases the complexity of the system out of thin air."

Just after he finished complaining, Engineer Liu next to him added:

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

In fact, Chang Haonan heard relevant analysis a long time ago and believed that the reason for this peculiar design idea is because the Soviet-style sea-based vertical hair, whether 3K95 or long-range S300F, is a direct replacement of the single/double arms of earlier years. The product of the launcher.

It is equivalent to hiding the launcher directly under the deck to prevent high sea conditions from adversely affecting the missile and launch system.

Under this idea, it is almost a logical idea for 8 rounds to share a launch port——

The 9K90 single-arm launcher on the modern level has only one firing position for 24 rounds of ammunition.

It's just that later people have seen Aegis's kind of hanging hair, and looking back, of course they find everything strange.

"So you just got four sets of Lu Ji Doyle's hair hanging devices?"

Chang Haonan looked at the four rectangular metal boxes and found that they did look a bit like the ones from 9K330.

"It's not directly from the Army."

Lin Qing explained:

"Actually, the Russians themselves thought the wheel-launching mechanism was very strange, so they had already designed this kind of 8-unit vertical launcher. However, they never launched new ships, so they had no place to install it."

"After we learned about this situation, we packed this set of equipment back together with several battalions of 9K330s and some related technical information..."

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