Chapter 1008: Are we starting to develop an integrated power system now?

Zhang Weiyong put down the cup, showing a "numb" expression, and pounded his chest twice at the same time, so that the breathing that was not smooth just now could be evened out.

"Wait a minute, wait a minute..."

After recovering from his shock, he quickly stopped Chang Haonan from continuing:

"Mr. Chang, please forgive me for being blunt..."

"For a satellite constellation consisting of three satellites, not to mention the preparations for the project and the verification of the principle, even if we skip these steps and start the project today, it will take about two to three years from the beginning of research and development to the successful launch into orbit..."

“That’s why I set a two-year goal…”

Chang Haonan's answer emphasized the sense of being natural, which made Zhang Weiyong seem a little surprised.

"No...but..."

The latter didn't know how to respond for a moment, and hesitated for a long time without uttering a single word.

"During the preliminary research phase, we can also do something..."

Seeing that Comrade Lao Zhang was a little bit overwhelmed, Chang Haonan tried to comfort him:

"A low-orbit communication relay satellite does not need to be very large. 24 transponders are enough. Dongfanghong- should be a very mature platform now. I can first provide you with some hardware requirements for network coding technology. It would be best if the overall design of the satellite can be solved on paper before the project is launched. After the project is officially launched next year, we only need to debug the equipment and adapt the software and hardware. It is not an exaggeration to complete it in two years..."

Zhang Weiyong didn't say anything.

He just stared at Chang Haonan in amazement.

My goodness, other people’s preliminary research is to study the feasibility, and at most add the demonstration of some key technical nodes.

It is essentially a process that is more management-oriented than technical.

As a result, for you, preliminary research is just completing half of the project, right?

Chang Haonan also saw Zhang Weiyong's doubts, so he brought out his past successful experience:

"Don't worry, I did the same thing when I led the team to develop the WS-10 and the heavy-duty forging press."

"The initial funding is definitely insufficient, but by combining past development experience and technology to reduce some unnecessary experiments, we can still push forward the progress normally..."

"..."

Next, Chang Haonan spent about ten minutes sharing some of his own experiences with the other party.

It is hard to say whether it had any practical effect, but in the end, Zhang Weiyong agreed to his proposal.

The first official test of Ocean No. 1 ended with such an "unexpected gain".

……

Throughout the entire month of April, Chang Haonan prepared for the project establishment of the QC300 gas turbine as he had planned.

As the project chief engineer, he has relatively little specific technical work to be responsible for, but most of the coordination and management tasks fall on him.

Especially the matters related to cooperation with Shipbuilding Heavy Industry 703 Institute——

After the previous seminar, senior executives from both groups quickly approved the proposal to jointly develop a new 30-megawatt power gas turbine.

Considering that the Navy and the 701 Institute responsible for the overall design both preferred the second option at the time, which was to continue to make in-depth improvements on the basis of 052C and enlarge the hull to 8000 tons, the benchmark research and development of the cooperation was finally determined to be QC300.

In other words, the 703 Institute of Shipbuilding Industry Corporation will participate in the research and development of QC300 in the form of "technology investment".

The main design work involves two parts: the casing and the intercooler.

But the dominance of models still lies in the hands of the 606th Institute of Aero-Power.

In fact, it is equivalent to completing the selection.

However, the 703 Institute, which "failed" in the selection, can also obtain part of the funds and profits to support it in continuing to complete the localization and upgrading of GT25000.

It's a happy ending.

In this case, it is equivalent to directly completing the project proposal and feasibility study.

As for the initial design...

QC300 is a modified turbofan 10 aircraft.

The latter's current performance in the Air Force is the best explanation of its preliminary design.

Therefore, the project approval was naturally passed with ease.

It didn't even alarm the Science and Technology Commission or even higher-level leaders like the WS-10 incident did.

The project was finalized by only four direct participants: the General Armament Department, the Navy, the Aviation Power Group, and the Shipbuilding Industry Corporation.

After the project review meeting was over, the deputy chief engineer sent by the 703 Institute slowed down and found Chang Haonan:

"Mr. Chang, please stay."

The latter was packing up to leave when he heard someone calling him, so he looked in the direction of the voice:

"Oh...it's Mr. Changshan..."

He stopped what he was doing and turned to face the person who came:

"If you have something to say, tell me."

Coincidentally, the deputy chief engineer's surname is also Chang, and his name is Changshan.

In fact, it is not uncommon for the top two leaders to have the same surname.

Just call them Mr. Chang and Little Mr. Chang and that's it.

In the beginning, everyone indeed called it that.

Until one day, when Chang Haonan and Chang Shan were standing together, someone called them "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 on, everyone simply changed the way they addressed Changshan to General Changshan.

The situation in Changshan is very special.

Institute 703 sent him here not to compete with Chang Haonan for the leadership of the project, nor to cooperate with Chang Haonan.

It's related to another project.

Changshan’s area of ​​expertise is not gas turbines, but transmissions.

He was in charge of the research and development of the diesel-fuel alternating system on the 052B/C.

The transmission efficiency is very high, and more importantly, the mean failure interval far exceeds the design requirements, and the evaluation is quite good.

So, it was natural for him to become the chief designer of the transmission system of 052D.

In the new models, the "柴" in the diesel-fueled fuel has not changed.

Therefore, Changshan’s main job is to adapt his transmission system to QC300.

Only then did I come here and sign up.

To put it bluntly, as the deputy chief engineer, he did not participate in the actual work of the project, but only wanted to fully understand the situation of QC300.

Therefore, being stopped by Changshan today was somewhat beyond Chang Haonan's expectations.

"That's it."

Chang Shan sat opposite Chang Haonan.

Perhaps because the two were not familiar with each other, the movements were a little stiff:

"I heard from Chief Engineer Lin Qinglin of the 701 Institute that you, Mr. Chang, have designed a fault fusion diagnosis system for the Type 054 frigate before?"

When the other party suddenly brought up this matter, Chang Haonan actually felt a little strange.

However, after a little thought, he replied:

"Strictly speaking, it was actually designed for the LNG ship of the Hudong plant, and the 054 was just a byproduct."

"After all, if there is a problem with an LNG ship...especially the cargo tanks, or the overall structure, it would be a big deal, so we designed this system considering the safety of the entire ship."

"So, although it is called a fault fusion diagnosis system, its focus is still on several aspects related to structural safety. It has relatively few functions when used on warships... For example, the combat system cannot be included in the diagnosis, including the power system. It can only diagnose the approximate location, and engineers still need to conduct detailed inspections."

"You are a transmission engineer, so you should know that... the power system of a ship is usually relatively independent, and the ship's electrical system is another system."

Hearing this, Changshan nodded continuously:

"Yes, I know that."

"In fact, I came to you today specifically to ask you whether this fault fusion diagnosis system can be made more perfect?"

Chang Haonan did not reply, but showed a slightly puzzled look.

"That is, 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-repair?"

Changshan explained further.

"hiss……"

Chang Haonan slowly sat up straight.

The idea proposed by the other party was 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 quite difficult to achieve it now.

“It can actually be achieved at the algorithm level…”

He stroked his chin and answered while choosing his words:

"But all systems on the ship must be highly integrated so that the system can obtain the overall situation of the ship in all directions. In addition, it will require one to two orders of magnitude more sensors than the current ones, as well as a master control computer with computing performance no less than that of a supercomputer. These things... it is probably difficult to provide enough energy with just two diesel generators."

"In addition, automatic fault repair cannot repair the hardware. We can only adjust the equipment working parameters to delay the occurrence of the fault as much as possible after the potential fault is discovered. However, this requires the ship to achieve fully automated control..."

"In short, it's 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 concluded.

"Then Mr. Chang."

At this time, Changshan showed a somewhat mysterious smile:

"What if I say... it's coming soon?"

"Ok?"

Chang Haonan was suddenly shocked by the riddle.

Chang Shan, who had something to ask of him, did not continue to keep the secret:

"Our 703rd Institute, Shanghai 704th Institute, Bingcheng University of Engineering and Naval University of Engineering are planning to build a technology verification ship together, combining the power and ship power into one unified management system."

"In this way, the ship is equivalent to being driven by electricity, and the gas turbine or diesel engine is decoupled from the propeller, so it can always operate in the highest efficiency range, and can also achieve faster response speed and stability; and because it is a high-power power machine that directly generates electricity, the supply of electricity is no longer a problem, which is equivalent to directly solving all the problems you mentioned just now..."

"..."

This time, it was Chang Haonan's turn to be stunned by others.

As a result, he didn't even hear clearly the last few words Changshan said.

The thought in my mind almost came out:

"No...it's only 2002, and you're already considering building an integrated power system?"
