Chapter 1008 Are you starting to build an integrated power system now?
?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 from continuing:
“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 takes about two to three years..."
“That’s why I set a two-year goal...”
?Chang Haonan''s answer was obvious, but it seemed that Zhang Weiyong was a bit unusual and strange.
“Not…but…”
The latter didn''t know how to respond for a moment, 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 Zhang who was a little nervous, Chang Haonan gave some guidance:
"The low-orbit communication relay satellite does not need to be very large. 24 transponders are enough. Dongfanghong-3 should be a very mature platform now. I can first provide you with some hardware requirements for network coding technology. It is best to The overall satellite design can be solved on paper before the project is approved. 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 guys, other people’s pre-research is to study the feasibility, and at most add some demonstrations of key technical nodes.
Essentially, it is a process that is more management than technology.
As far as the results are concerned, the pre-research is to complete half of the project, right?
Chang Haonan also saw Zhang Weiyong’s uncertainty, so he cited his past successful experience:
“Don’t worry, I did the same thing when I led the team to develop the turbofan 10 and the heavy-duty die forging press.”
“The initial funding is definitely insufficient, but by combining past development experience and technology to reduce some unnecessary experiments, progress can still be pushed forward normally…”
…”
Next, Chang Haonan spent about ten minutes sharing some of his 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 gain".
…
Throughout the following April, Chang Haonan prepared for the project establishment of the QC300 gas turbine as he had planned.
?As the chief engineer of the project, he is responsible for relatively few specific technical tasks, but most of the coordination and management tasks fall on his head.
?Especially matters related to cooperation with Shipbuilding Industry 703—
After the previous seminar, the top leaders of both groups quickly approved the proposal to cooperate in the research and development of a new 30-megawatt power gas turbine.
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 703 will participate in the research and development of QC300 in the form of “technical investment”.
Mainly involved in the design work of the casing and the intercooler.
But the model dominance is still in the hands of Aerodynamics 606.
In fact, it is equivalent to completing the selection.
It’s just that 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 can be considered a happy ending.
In this case, it is equivalent to directly completing the project proposal and feasibility study.
As for the preliminary design…
The QC300 is a turbofan 10 aeroderivative.
The latter’s current performance in the Air Force is the best preliminary design illustration.
Hence, the project approval was naturally passed smoothly.
It did not 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 getting ready to leave. When he heard someone calling him, he followed the sound and looked over:
“Oh…it’s Mr. Changshan…”
?He stopped what he was doing and turned to face the person:
“If you have something to say, please tell me.”
It is a coincidence that this deputy chief engineer also has a surname of Chang, and his name is 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 and that’s it.
At the beginning, that’s what everyone called it.
?Until one day, when Chang Haonan and Chang Shan were standing together, someone called Mr. Chang.
Then they both raised their heads at the same time... The chief engineer is much younger than the deputy chief engineer, which is sometimes a problem...
So later, everyone’s name for Chang Shan was directly changed to General 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.
Instead, it is related to another project—
Changshan’s area of ??expertise is not gas turbines, but transmissions.
The alternating diesel-fuel 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.
Hence, he naturally became the chief designer of the transmission system of 052D.
In the new model, the "chai" in the alternation of diesel and combustion has not changed.
Hence Changshan’s main job is to adapt his transmission system to the QC300.
?Just then he ran over and asked for his name.
To put it bluntly, he, the deputy chief engineer, did not participate in the actual work of the project, just 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 opposite Chang Haonan.
?Perhaps because the two of them are not familiar with each other, their movements are a little stiff:
“I heard from Chief Engineer Lin Qinglin of the 701 Institute that, Mr. Chang, you have designed a fault fusion diagnosis system for the Type 054 frigate before?”
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 of 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, and Only the approximate location can be diagnosed, and engineers still need to conduct detailed inspections.”
“If you are engaged in transmission, you should know...the power part of a ship is generally relatively independent, and the ship’s electricity is another set of things.”
Hearing this, Chang Shan couldn’t help but nod:
“Yes, I know that.”
“Actually, I came to you specifically today to ask, can this fault fusion diagnosis system be made more complete?”
?Chang Haonan did not 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.
…
?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 considered his words as he answered:
"However, each system of the entire ship must be highly synthetic, so that the system can obtain the overall situation of the ship in an all-round way. In addition, one to two orders of magnitude more sensors are needed than at present, and the computing performance is no less than that of a supercomputer. The main control computer, these things...it is difficult to provide enough energy with just two diesel generators.”
"In addition, automatic fault repair cannot be done by repairing the hardware. We can only delay the outbreak of the fault as much as possible by adjusting the equipment working parameters after discovering the hidden fault. However, 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 no place to install it.”
Chang Haonan finally concluded.
“That’s Mr. Chang.”
At this time, Chang Shan showed a somewhat mysterious smile:
“What if I say...it will be available soon?”
"Um?"
Chang Haonan was immediately surprised when he was suddenly asked a riddle.
Chang Shan, who had something to ask for, did not continue to sell out:
“Our 703rd Institute, Shanghai 704th Institute, Bingcheng Engineering University and Naval Engineering University are preparing to build a technology verification ship together, integrating power and ship electricity into one, and integrating them into one system for management.”
"In this way, the ship is equivalent to being driven by electricity, and the gas turbine or diesel engine is decoupled from the propeller. It can always work in the highest efficiency range and obtain faster response speed and stability; and because the high-power power machine directly generates electricity, Therefore, the power supply is no longer a problem, which is equivalent to directly solving all the problems you just mentioned..."
…”
?At this time, 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’re already considering building an integrated power system?”
