Chapter 854 Normal hanging hair
For the purpose of keeping secrets and preventing enemy agents from sabotaging, the military and civilian business of the Hudong Factory is physically separated. In addition, Lin Qing is from the 701 Institute after all. , so I have only heard about the LNG ship project.
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, his whole body suddenly became energetic:
"In order to meet the requirements of maintenance According to the demand, we specially left some space margin for the power cabin during the design, if a sensor is 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 cannot detect anything. It must directly cooperate with the power system itself."< br>
“With the power system itself...”
After hearing this, Lin Qing’s expression froze:
"Does this mean that these two gas turbines have to be dismantled and modified?"
Now that the ship segments are almost completely closed, if the equipment in the segments is modified again, 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.”
“Huh——”
This reply made Lin Qing relieved:
“It doesn’t matter, anyway. The engine room of a warship must always be manned, and we mainly use this function during the maintenance process.”
Theoretically, the power system of a modern ship is directly controlled by the bridge. 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 freighter of 100,000 tons or even hundreds of thousands of tons may only have twenty or thirty crew members. people.
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 I have never calibrated the parameters of a gas turbine, so if I want to achieve complete functions, I am afraid I have to cooperate with the turbine design unit and the shipyard.”
Before the words could even be finished, Lin Qing and the engineer named Liu next to him said almost in unison:
“No problem, we will definitely cooperate in business matters!”
Wu Wentao next to him also followed suit. Agree.
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...I am mainly worried about efficiency..."
Chang Haonan sighed:
"This system is still in the development stage. Torch Group's Ordinary employees are not very familiar with it. If they only rely on the two of them, it would be a bit troublesome to travel from both ends."
"Well..."
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 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 talks little, suddenly suggested:
"I've talked to 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:
"I'll ask for his opinion when I get back. We still need to refer to it in the research field. Opinions from the students themselves. "
"It really doesn't work. I plan to recruit a group of postdocs and researchers in a few months. Anyway, the technology is in our hands, and the manpower problem will always be solved. Method.”
"Okay..."
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 next to him. green.
"Okay."
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 and took a look around to see what had been delivered. Cargo's 3K95 ship-to-air missile system.
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. He asked with a surprised look on his face:
“The launching device of this 3K95 should have 8 rounds arranged in a cylindrical shape?”
“Yes, the original version is like this.”
Lin Qing nodded:
"8 rounds, similar to the magazine of a revolver, but there is only one firing port, and there is a rotating mechanism below."
"But we want to break I don’t even understand why this strange launch method is used, which does not save space or cost, but also increases the complexity of the system out of thin air.”
As soon as he finished complaining, Engineer Liu next to him said again. Added:
"Moreover, the land-based 9K330 actually already has a set of 8-link launch boxes with mature technology, 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 below 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 only has one for 24 rounds. launch location.
It’s just that later people have seen Aegis’s kind of hanging hair, and looking back, of course, everything seems strange.
"So you just got four sets of Luji Doyle's hair hanging devices?"
Chang Haonan looked at the four rectangular metal boxes and found that they did seem to be somewhat similar to the one in 9K330.
“It’s not directly from the Army.”
Lin Qing explained:
“In fact, the Russians themselves also think that the wheel launcher mechanism is very strange, so they have They designed this kind of 8-pack hanging hair, but they never launched a new ship, so they had no place to install it.”
"After we learned about this situation, we packed this set of things back together with several battalions of 9K330s and some related technical information..."
"Even if the 054 is changed to a larger size in the future , a domestic vertical launcher that can launch medium-range or even long-range missiles, this relatively small close-in defense system will definitely have its place.”
