The military-industrial scientific research system of the academic master.

“Release private capital?”

Although Dordan had just behaved like an ordinary old man who was persistent and nagging others, since he had become the top leader in the European Space Agency where interests were complicated and relationships were tangled, he must not be a fool.

Almost at the same time as Kandel's voice fell, his whole aura instantly became sharp, and his fox-like eyes narrowed slightly, scanning the former several times back and forth.

However, after just a few seconds, Dordan regained his previous amiable image.

It was as if the changes just now had never existed.

"Now that you mention it, it reminds me... It seems that in 2000, a company of similar nature was established in the United States. It should be called Blue Origin?"

He did not respond directly to Kandel's suggestion, but instead brought up a topic that seemed related, but not particularly closely.

The latter was stunned when he heard this, and seemed to have not expected the other party to suddenly bring up the matter in the United States, but he quickly nodded:

“Yes, it was founded by an Internet business owner named Jeff Bezos.”

In 2003, the world had not yet fully recovered from the previous round of Internet bubble, and Bezos was not yet the world-famous richest man he later became.

For outsiders, it is normal to have never heard of it or feel unfamiliar with it.

"But I heard that the company is currently only conducting some research on suborbital spacecraft?"

Obviously, Dordan was not completely unaware of this.

Kandel realized that he had entered the opponent's rhythm and reacted quickly:

"It doesn't matter... You don't expect this company to come up with anything anyway. You just need a clean and safe medium to hedge your bets."

He shrugged:

"Of course, as the space regulatory agency, ESA must have the corresponding supervisory power... But as long as this market can be opened, no matter what is done, it is purely commercial behavior. Since it is a commercial behavior, there are a hundred ways to circumvent supervision..."

Dordan quickly grasped the other party's point.

It is not the private capital mentioned above.

It's a business behavior.

“You want the space industry to be commercialized?”

He changed his previous way of speaking which was always beating around the bush and went straight to the point.

Such a rapid change caught Kandel off guard.

"It's not that I want it...but that you need it."

He still hopes to get by with a painless way:

"As long as ESA is deeply involved in a project, NASA will definitely get the news faster than you, the director...Instead of this, it is better to let ESA just be the first party, at least NASA can be confused with you."

However, Dordan was not so easily fooled:

"Bernard..."

He showed a somewhat weird smile:

"I know that after you left ESA, in addition to being a nominal consultant and honorary professor, your main job has always been an independent analyst..."

At first, Dordan invited Kandel over just to ask for advice.

But when the latter talked about commercial space travel, he realized that the other party actually needed his help as well.

Kandel's smile froze on his face after being directly exposed.

But it only lasted a short time:

"All right……"

Now that things have come to this, if I continue to deny it, it will affect our friendship:

"I do have many clients who hope that NASA or ESA can start the commercialization process of the space industry, such as launching a commercial orbital transportation service... You know, after the Internet bubble, a lot of hot money has no good place to go. If it keeps idling for a long time, the risk will be very high..."

"But this will not be a loss for you or the entire ESA. The ELDO faction can get rid of NASA's control to a certain extent and obtain the multi-party cooperation they want. After commercialization, a considerable portion of the orders will definitely be given to American companies. The ESRO faction will not have any objections. If they are all satisfied, you will naturally be able to sit more securely as the director..."

"And you, as the middleman, can also get a huge commission from it."

Dordan spoke directly, interrupting the other party's empty promises.

"really."

Kandel did not deny this:

“So, this is not a bad thing for all of us.”

In fact, the so-called commercial space flight is very simple.

It's outsourcing.

At first glance, it doesn't sound like a good word.

However, for organizations like NASA or ESA that have become bloated and inefficient for various reasons, outsourcing can actually reduce a lot of trouble.

Therefore, Dordan did not refuse immediately, but thought about it for a while:

“Commercialization…I’m afraid it’s not as easy as you think.”

This response seems to be negative.

But in fact, there is enough room.

"So...it's not necessary to do it all at once."

Kandel smiled:

"First, we can start with some simple projects, and by the way, we can test the depth of Chinese people..."

Dordan still didn't nod.

But there was already some looseness in his eyes...

……

Commercial space travel is naturally not something that can be promoted by a few people and a few words.

Chang Haonan naturally had no idea that his seemingly unrelated actions would even affect the landscape of the aerospace industry.

For nearly the next month, he spent most of his time at Torch Group, testing several typical multi-objective optimization algorithms.

With Chang Haonan's current theoretical foundation, plus a little help from the system, this task is not difficult at all.

The workload is indeed staggering.

In the past thirty years, there have been no less than two dozen multi-objective evolutionary algorithms proposed by academia, even if we only consider those with application value.

Combined with the three improvement ideas proposed by Chang Haonan...

Even if we can directly rule out a part of it through theory, the remaining number is by no means a small number.

Fortunately, for the entire adaptive machining technology, this algorithm is a relatively isolated part. It is only used to determine the clamping methods of different types of workpieces and will not affect the development of machine tool hardware and industrial control programs.

Until one night in early December.

Chang Haonan ended his short break and walked into the computer room as usual.

But this time, what appeared before him was not the scene of a group of researchers busy shuttling back and forth.

Instead, more than a dozen people, including Wei Yongming, sat around a computer and whispered.

For a moment, no one even noticed Chang Haonan coming in from outside.

Finally, he leaned over and asked:

"Is there any progress?"

The sudden voice coming from behind scared several of them.

Wei Yongming also stood up quickly:

"Boss Chang, the comparison results are out."

Although when he saw this situation, Chang Haonan guessed that there must have been a breakthrough.

But it was quite unexpected to reach the finish line directly:

"All out?"

"Yes."

Wei Yongming directly stuffed a report that had just been printed out next to him into Chang Haonan's hands:

"Sample No. 14 is a particle swarm algorithm that uses Gaussian sampling of the global best position and the best position of individual particles to replace the particle velocity update formula. Sample No. 22 is a genetic algorithm that has undergone dimensionality reduction optimization. The results of these two groups of tests are significantly better than the other groups. In fact, they are also better than our initial estimates. However, it is still unclear which one is better..."

The optimized particle swarm algorithm was something that Chang Haonan was optimistic about in advance.

Of course, the result did not disappoint him.

As for the other one...

"No need to conclude."

Chang Haonan quickly looked at the final result:

"Take it to the production end and test it in practice!"

In fact, he didn't really have to compete with the other party.

When there are only two options left and the performance is comparable, the final result is definitely "I want them all".

Let the customer decide which algorithm to use based on the actual situation.

The reason why we proposed to do production testing was just that we happened to catch up...

"Has Lao Yang completed the hardware adaptation?"

Wei Yongming's movements of organizing the documents paused.

Even though he and Chang Haonan are responsible for the industrial control system and the clamping and positioning algorithm, as for the software aspects, as long as they have a solid theoretical foundation and their ideas are straight, they can produce results relatively stably.

On the contrary, it is the hardware aspect.

Machine tools are not home computers and their compatibility is far less than that of the latter.

After the industrial control system is updated, it often takes a lot of effort to adapt it.

Especially since most of the action system comes from Italy, so we have to coordinate with them in the middle.

And the Italian efficiency...

All I can say is that everyone who understands understands.

"What a coincidence! It just passed the inspection yesterday..."

Chang Haonan showed a satisfied smile.

……

Based on the principle of software adapting to hardware, production testing must naturally be carried out in the workshop of Torch-CB Ferrari.

As Yang Weihua said before, the adaptive machining prototype was improved based on an MS45T three-axis CNC machining center.

Therefore, from the appearance point of view, it seems to be no different from the same product next to it.

However, after the machine tool is started, the production data that needs to be imported is much more complicated than that of the old model.

Three-axis machining centers cannot produce overly complex surfaces.

For example, when milling the flow channel of an impeller, the milling cutter needs to extend into the flow channel. If there is no swing head on the spindle or no turntable on the workbench, the processing cannot be completed.

Therefore, Chang Haonan simply provided a typical aluminum alloy aircraft structure as a test object.

The clamping and positioning algorithm itself is very complex and it is impossible to complete the calculation through the machine tool itself.

But the MS45T allows external devices, which largely makes up for this shortcoming.

"The test begins!"

Following Chang Haonan's order, a group of technicians began their preparations.

Soon, the algorithm control parameters and workpiece processing plans were input into the computer.

"The axial cutting depth was set to 6 mm, and a non-uniform machining sequence was used. A total of 168 intermediate state centroids were generated, of which 159 (94.64%) centroids were enclosed by the optimized fixed clamping area. After 18 rounds of iterations, the objective function converged to 0.7789..."

“三个定位点坐标分别为A(394.73，-219.87)、B(367.00，0)、C(292.07，-218.40)……”

"..."

Wei Yongming had just finished reporting the calculation results when Yang Weihua had already completed the three-point fixation of the thin plate blank to be processed.

The next step is to import the processing program into the industrial control system.

Since the code had already been written in advance, the whole process took less than 10 minutes.

After the safety officer finally confirmed that the equipment was in good condition, the protective cover was closed.

Immediately afterwards, everyone heard the sound of cutting fluid hitting the milling cutter and the milling cutter cutting the raw material.

The protective cover shell has a transparent window for the operator to see the working conditions inside.

However, this kind of precision processing cannot be seen with the naked eye.

Fortunately, after being upgraded, the MS45T can directly display the measured value of the cutting force.

Therefore, just by glancing at the screen, you can get a general idea of ​​the machine's current operating status.

In fact, the general processing flow is not much different from the traditional method.

It is just because the cutting edge needs to be changed to calculate the compensation amount, so the cutting speed is obviously slowed down, and the interval between each two rounds of action is also extended a lot.

But it saves the process of artificial stress release.

It also reduces the errors caused by repeated clamping.

Even more, some areas that fail to meet the requirements will be compensated twice...

In short, it highlights the peace of mind.

Yang Weihua looked at the knife-moving steps that kept popping up on the screen in front of him, and suddenly felt a little dazed:

"Boss Chang, if all products can be processed this way in the future, wouldn't it be enough to just input a few parameters... or even not require personnel to be on site to operate in person?"

Chang Haonan touched his chin gently:

"It will not be possible to achieve this level in a short period of time, and this is just a relatively simple process like cutting."

"However, this can indeed be regarded as the first step in intelligent production..."
