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 to make the breath that was not smooth just now even.

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

After recovering, he quickly stopped Chang Haonan from continuing:

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

"A satellite group consisting of three satellites, not to mention the preparation for the project establishment and the principle verification, even if we skip these steps and establish 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 a sense of course, which made Zhang Weiyong seem a little surprised.

"No... but..."

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

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

Looking at Comrade Zhang who was a little bit overwhelmed, Chang Haonan said:

"Low-orbit communication relay satellites do 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 solve the overall design of the satellite on paper before the project is established. After the project is officially established 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 did not speak.

Just stared at Chang Haonan in astonishment.

Good guy, other people's pre-research is to study the feasibility, and at most add some demonstrations of key technical nodes.

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

As a result, in your case, the pre-research is to directly complete 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 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, we can still push the progress forward normally..."

"..."

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

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

And the first formal test of Ocean No. 1 ended in such an "unexpected harvest".

...

In the whole of April, Chang Haonan prepared for the project establishment of the QC300 gas turbine as he had planned before.

As the chief engineer of the project, he had relatively few specific technical tasks to be responsible for, but most of the coordination and management tasks fell on his head.

Especially the cooperation with the 703 Institute of Shipbuilding Industry --

After the previous seminar, the top leaders of both groups quickly approved the proposal to jointly develop a new 30MW power engine.

Considering that the Navy and the 701 Institute, which was responsible for the overall design, preferred the second option at the time, that is, to continue to make in-depth improvements on the basis of 052C and enlarge the hull to 8,000 tons, the benchmark research and development of the cooperation was finally determined to be QC300.

In other words, the 703 Institute of Shipbuilding Industry will participate in the development of QC300 in the form of "technical investment".

Mainly the design work of the casing and the intercooler.

But the model dominance is still in the hands of the 606 Institute of Aviation 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 from it to support its continued completion of the localization and upgrading of GT25000.

It is a happy ending.

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

As for the preliminary design...

QC300 is the turbofan 10 aero-fuel.

The latter's current performance in the Air Force is the best preliminary design description.

Therefore, the project approval was naturally passed.

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

The project was decided by the four direct participants, the General Armament Department, the Navy, the Aviation Power Group and the Shipbuilding Heavy 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 up and preparing to leave. When he heard someone calling him, he 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, tell me."

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

In fact, it is not uncommon for the first and second in command to have the same surname.

Just call them Mr. Chang and Mr. Xiao Chang respectively.

At the beginning, everyone did call them that.

Until one day, when Chang Haonan and Chang Shan were standing together, someone called him "Little Chief 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 changed the way they addressed Chang Shan to "Chief Chang Shan".

And this Chang Shan's situation 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——

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

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.

Therefore, he naturally became the chief designer of the transmission system of 052D.

In the new model, the "chai" used for alternating diesel and combustion has not changed.

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

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, but only wanted 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 from Chief Engineer Lin Qinglin of the 701 Research 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. It can only diagnose the approximate location, 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 a different set of things."

Hearing this, Chang Shan couldn't help but nod:

"Yes, I know that."

"Actually, I came to you today specifically to ask, can this fault fusion diagnosis system be made more complete?"

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 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 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 adjust the equipment working parameters to delay the outbreak of the fault as much as possible after discovering the hidden fault. 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 no place to install it."

Chang Haonan finally concluded.

"Then 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 shocked when he was suddenly asked a riddle.

Chang Shan, who wanted to ask for help, did not continue to lie:

"Our 703rd Institute, Shanghai 704th Institute, Bingcheng University of Engineering and Naval Engineering University are planning to build a technology verification ship together, combining 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..."

"..."

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're already considering building an integrated power system?"
