Chapter 1008 Is this the beginning of a comprehensive power system?
Zhang Weiyong put down the cup with a "numb" expression on his face, and at the same time punched his chest hard twice to calm down the breath he had just been having.
"You wait a minute, you wait a minute..."
After he recovered, he quickly stopped Chang Haonan and continued:
"Mr. Chang, with all due respect... …”
"For a satellite constellation consisting of three satellites, let alone preparations for project approval and proof of principle, etc., even if we skip these steps and establish the project today, from the beginning of research and development to the smooth launch into orbit, it will be a long time. It needs a cycle of about two to three years..."
"That's why I set a two-year goal..."
Chang Haonan's answer highlighted a natural thing, but it seemed that Zhang Weiyong It's a bit rare and strange.
"It's not...but..."
The latter didn't know how to respond for a while, and he hesitated for a long time without uttering a word.
"In the pre-research stage, we can also do some things..."
Looking at Comrade Lao Zhang who was a little nervous, Chang Haonan enlightened:
"Low-orbit communication relay satellite It doesn’t need to be big, 24 transponders are enough. Dongfanghong-3 should be a very mature platform now. I can provide you with some hardware requirements for network coding technology first. It would be best if the satellite can be installed before the project is established. The overall design has been solved on paper. After the project is officially approved next year, only equipment debugging and software and hardware adaptation will be required. It is not an exaggeration to complete it in two years..."
Zhang Weiyong said nothing.
Just looked at Chang Haonan dumbfounded.
Good guy, other people's pre-research is to study feasibility, and at most add some demonstrations of key technical nodes.
Essentially, it is a process in which management is greater than technology.
The results are here for you. Pre-research is just about completing half of the project, right?
Chang Haonan also saw Zhang Weiyong’s uncertainty, so he cited his past successful experience:
“Don’t worry, I led the team to develop the turbofan 10 before, and that heavy-duty mold The same thing is done when forging a press.”
"The initial funding is definitely insufficient, but by combining past development experience and technology to reduce some unnecessary experiments, we can still promote progress normally..."
"..."
Next, Chang Haonan It took about ten minutes to share some of my experiences with the other party.
It’s hard to say whether it had any actual effect, but in the end Zhang Weiyong agreed to his proposal.
The first formal test of Ocean One ended with such an "unexpected harvest".
...
For the entire next April, Chang Haonan prepared for the QC300 gas turbine project as he had planned.
As the chief engineer of the project, he has relatively few specific technical tasks to be responsible for, but most of the coordination and management tasks fall on his head.
Especially matters related to the cooperation with Shipbuilding Industry 703——
After the previous seminar, the senior leaders of both groups quickly approved the cooperation in the research and development of 30-megawatt new type Power gas turbine proposal.
Considering that both the Navy and the 701 Institute responsible for the overall design preferred the second option at that time, which was to continue to make in-depth improvements based on the 052C and enlarge the hull to an 8,000-ton class, the baseline research and development for cooperation was finally determined. for QC300.
In other words, Shipbuilding Industry Institute 703 will participate in the research and development of QC300 in the form of "technical investment".
Mainly the design work of the receiver and the intercooler.
But the model dominance is still in the hands of Aviation Power 606.
In fact, it is equivalent to completing the selection.
However, the 703 institute that "failed" in model selection can also obtain part of the funds and profits to support its continued localization and upgrade of GT25000.
It’s a happy ending.
This situation is equivalent to directly completing the project proposal and feasibility study.
As for the preliminary design...
QC300 is a turbofan 10 aeroderivative.
The latter's current performance in the Air Force is the best preliminary design illustration.
Therefore, the project approval was naturally passed smoothly.
It didn’t even alarm the Science and Technology Commission or even higher-level leaders like the Turbofan 10 did.
The project was finalized by only four direct participants: the General Armament Department, the Navy, the Aviation Power Group and the Shipbuilding Industry Group.
After the project review meeting, the deputy chief engineer sent by the 703 Institute slowed down and found Chang Haonan:
"Mr. Chang, please stay."
The latter was packing his things and preparing to leave. When he heard someone calling him, he followed the voice and looked over:
"Oh...it's Mr. Changshan... ..."
He stopped what he was doing and turned to face the person:
"If you have anything to say, please tell me."
Coincidentally, this deputy chief engineer also has a surname of Chang Shan.
In fact, it is not uncommon for the first and second leaders to have the same surname.
Just call Mr. Chang and Mr. Xiao Chang respectively.
In the beginning, everyone actually called it that.
Until one day, when Chang Haonan and Chang Shan were standing together, someone called Mr. Chang.
Then the two of them raised their heads at the same time... The chief engineer was much younger than the deputy chief engineer, which was sometimes a problem...
So later, everyone changed the name of Chang Shan directly. He became President Chang Shan.
The situation in Changshan is very special.
The 703 Institute sent him here not to compete with Chang Haonan for project leadership, nor to cooperate with Chang Haonan's work.
On the contrary, it is related to another project——
Chang Shan’s area of expertise is not gas turbines, but transmission devices.
The diesel-fuel alternating system on 052B/C was developed by him.
The transmission efficiency is very high, and more importantly, the mean interval between failures far exceeds the design requirements, and the evaluation is quite good.
So, he naturally became the chief designer of the 052D transmission system.
In the new model, the "chai" used for alternating diesel and combustion has not changed.
So Changshan’s main job is to adapt his transmission system to the QC300.
Then he came over and asked his name.
To put it bluntly, he, the deputy chief engineer, does not participate in the actual work of the project, but only to fully understand the situation of QC300.
Therefore, being specifically stopped by Chang Shan today was somewhat beyond Chang Haonan's expectations.
"That's right."
Chang Shan sat across from Chang Haonan.
Perhaps because the two of them were not familiar with each other, their movements were a little stiff:
“I heard Chief Engineer Lin Qinglin from the 701 Institute say that Mr. Chang, you previously designed the Type 054 frigate. A fault fusion diagnosis system?”
Chang Haonan actually felt a little strange when the other party suddenly mentioned this matter.
However, after thinking for a while, he still replied:
"Strictly speaking, it was actually designed for the LNG ship at the Hudong Plant, and 054 just took advantage of it."
"After all, if there is a problem with the LNG ship...especially if there is a problem with the cargo tank or the overall structure, it will be a big deal. So we considered the safety of the entire ship and designed such a system."
"So, although it is called a fault fusion diagnosis system, it actually focuses on several aspects related to structural safety, and its functions are still slightly limited when used on warships... For example, the combat system cannot be included in the diagnosis, including The power system can only diagnose the approximate position, and engineers still need to conduct detailed inspections. "
"As a transmission person, you should know... The power part of a ship is generally relatively independent, and the ship's power is another. Set something up.”
Hearing this, Chang Shan couldn't help but nod:
"Yes, I know that."
"Actually, I came to you specifically today just to ask, can this fault fusion diagnosis system Can't we do it better?"
Chang Haonan didn't reply, but looked slightly confused.
“That is to say, in addition to fault location technology, is it possible to add functions such as fault control management, fault prediction and risk assessment, and even fault self-healing?”
Chang Shan further explained.
"Hiss..."
Chang Haonan slowly sat up straight.
The idea proposed by the other party is very close to his ultimate goal when developing this system.
But since it is said to be the ultimate goal, it means that it is indeed more difficult to do it now.
"It can actually be realized at the algorithm level..."
He touched his chin and answered while considering his words:
"But each system of the entire ship must have a high degree of synthesis so that the system can In addition, to obtain the overall situation of the ship in all directions, one or two orders of magnitude more sensors are needed than at present, as well as a master control computer whose computing performance is no less than that of a supercomputer. These things... only rely on two diesel power generation auxiliary engines. I'm afraid it will be difficult to provide enough energy. "
"In addition, automatic fault repair cannot repair the hardware. We can only delay the fault as much as possible by adjusting the equipment working parameters after discovering the hidden fault. time for the outbreak, but this requires the ship to achieve fully automated control..."
"In short, it is not difficult in principle, but in terms of engineering, there is no ship that can meet so many requirements at the same time... So there is nowhere to install it.”
Chang Haonan finally concluded.
"Then Mr. Chang."
At this time, Chang Shan showed a somewhat mysterious smile:
"What if I said...it will be available soon?"< br>
“Huh?”
Chang Haonan was immediately shocked when he was suddenly asked a riddle.
Chang Shan, who was asking for help, did not continue to sell out:
“Our 703 University, Shanghai 704 University, Bingcheng University of Engineering and Naval Engineering University are preparing to jointly conduct a technical verification of a ship. The ship combines power and ship power into one system and manages them in one system. "
"In this way, the ship is driven by electricity, and the gas turbine or diesel engine is decoupled from the propeller. Always working in the highest efficiency range, you can also achieve faster response speed and stability; and because the high-power power machine directly generates electricity, the power supply is no longer a problem, which is equivalent to directly solving all the problems you just mentioned. …”
“…”
Now, it was Chang Haonan's turn to be stunned by others.
So much so that he didn’t fully hear the last few words Chang Shan said.
The thoughts in my mind almost blurted out:
"No...it's only 2002, and you are already considering building an integrated power system?"
