This civilization is very strong, but the technology tree is a bit crooked

Compared to previous chemical fuel propelled drones.

There are already mature technologies and accessories on the market.

Chen Yi only needs to buy accessories, assemble them by hand, and then adjust the attributes to upgrade.

The current ion-propelled drones and Hall-propelled drones are breakthroughs from scratch.

This represents.

The overall system design and accessories of the ion propulsion drone, including every technology, all have to be studied by Chen Yi himself.

to this end.

Chen Yi spent more than half a month.

Except for the fifteenth day of the lunar calendar, the drone that controlled the moon landing into the lunar orbit took a close-up shot of the moon and posted a news, and did not broadcast live to keep a low profile.

In addition, I took the time to build a rotating detonation engine. The reading technology replaced the incomprehensible quantum material with a copper-based superalloy, and made a technical paper and sent it to Professor Zhang.

For the rest of the time, Chen Yi was busy with the technical details of the new drone.

Ask Professor Zhang for a list of relevant books and literature, and consume two opportunities for virtual learning.

Only then did the design and planning of his new drone be completed.

At the same time, this is also his first self-designed drone.

Towards a new milestone in the machine.

"Although the efficiency and specific impulse of the ion thruster are great, the thrust is notoriously small."

"In addition, according to the kinetic energy conservation and impulse formula, it can be calculated."

"With the same power, the faster the injection speed and the higher the impulse, the lower the quality of the injection and the smaller the thrust."

"So if you want to enter space from the ground through ion propulsion, the key is inseparable from four points."

"One is that the thrust can be adjusted, and the air can be taken in at low altitude.

The second is to increase the energy density, and the same mass releases higher energy.

The third is that the material structure is lightweight and empty, which reduces the weight of the fuselage itself.

The fourth is to enter space by only overcoming the planet's gravity and low-speed spaceflight.

To describe it vividly, ion propulsion plays on the durability of technology and external supplements.

You can't be as energetic, prosperous, and violent as a young man like chemical propulsion."

Chen Yi figured out his thoughts step by step.

The biggest disadvantage of ion propulsion is that the thrust is too small.

Take the HET-80 Hall thruster of Tianhe Space Station as an example.

The power is 1350W, which is equivalent to 1.8 horsepower, but the thrust generated by HET-80 is only 80 millinewtons.

The mass of an ordinary egg, after unit conversion, is about 500 millinewtons.

6 HET-80 Hall thrusters can push an egg.

Such an ion-propelled UAV can imagine how small the thrust is.

To enter space on the ground, different designs and technical means must be used.

"The design of the hardware system is completed, and the next step is the design of the avionics control layer"

Chen Yi took out his mobile phone and called He Yu.

Space drones don't go in orbit.

The avionics control system is inseparable from the assistance of artificial intelligence.

In this way, before manufacturing drones, artificial intelligence also needs to be arranged.

"Hello, Mr. He.

Recently, I have a new idea. The studio wants to order a supercomputer.

The cost of overcalculation will be deducted from the patent authorization payment of the studio later. "

After waiting for a few seconds, He Yu answered the phone.

Chen Yi was not polite, and stated his request straight to the point.

Now Yifei has completed industrial and commercial restructuring.

The entire wing fly is divided into two parts.

Part of it is Chen Yi's studio and the laboratory being acquired, responsible for technology development.

The other part is Yifei New Company managed by He Yu, which is responsible for market operation, production, sales, etc., except for technology development.

And Yifei's technology is authorized through an agent.

Authorized by Yifei Studio and handed over to Yifei Company.

Yifei new company.

He Yu, who is following up the renovation and construction of the factory and handling company affairs.

Hearing Chen Yi's request, he subconsciously opened the report.

View the company's most recent sales totals, as well as total pre-orders.

After looking at it, He Yu replied to Chen Yi: "Mr. Chen, what is the approximate budget for what you want?"

"Around 100 million."

Chen Yi analyzed the requirements for cultivating and upgrading artificial intelligence, and gave a price.

"."

He Yu's expression almost froze when he heard the price: "Mr. Chen, there are only less than 50 million left in the company's account. You are overcalculating, and the price is too high."

"No way, I think drone engines are pretty good recently.

The shipment volume exceeded 20,000, and even if calculated based on the wholesale price of 25,000, this accounted for at least 500 million. "

A trace of doubt flashed in Chen Yi's heart.

For the drone engine he researched, he knew exactly how much it cost.

In Yifei's small workshop, the cost of manufacturing an engine was between 2000 and 2500 including raw materials, labor, equipment loss, positioning chips, electricity, etc.

Now that Yifei has acquired a larger and more well-equipped mechanical processing plant, the total production capacity has been increased to 50,000 yuan per month. The manufacturing cost of this engine can be further reduced, and it can be reduced to less than 2,000 yuan conservatively.

More than 80% of the 500 million payment for the shipment is profit.

But now, He Yu said that Yifei couldn't even get 100 million?

"."

He Yu rubbed his head: "Mr. Chen, I reported to you 10 days ago.

Yifei acquired a battery manufacturing company at a cost of 256 million.

Recently, it cost 89 million yuan to renovate the battery production workshop and order various materials and equipment.

Plus some others relocating company headquarters, acquiring labs, etc.

I have reported all these large expenditures of more than two million yuan to you, and I have also sent the cashier slip to Manager Qin for her to sign for you.

Don't you think you signed it without even reading it? "

"Yeah?"

Chen Yi thought for a while.

It seems that a few days ago, Qin Xiaoyu did take some financial statements for him to sign.

But at the time, he was busy designing his new drone, and almost forgot about it after signing it.

Chen Yi opened his company mailbox and checked the latest financial summary statement sent by the finance department.

It will be seen that Yifei's debt ratio is less than 10%.

This He Yu is still too conservative.

With such a low debt ratio, there is not enough money to get a loan?

Thinking of this, Chen Yi made a decision: "Mr. He, first borrow a loan to order one, under the name of Fangyifei's assets.

Wait for the follow-up patent dividends, and then transfer them to the studio in the form of capital offset. "

"May I ask you, what is Mr. Chen planning to do by buying this supermarket? Is the company going to develop new businesses in the data computing industry recently?"

He Yu was silent for a while, and decided to ask clearly.

"Suddenly I had an inspiration idea, and I need to use a supercomputer to verify it." Chen Yi didn't hide anything, and answered very simply.

"In this way, we can lease the supercomputer, and there is no need to spend so much money to buy it. The business of Yifei does not need to use the supercomputer for a long time."

"The experiment is more violent and may cause damage to the supercomputer. Buy it yourself."

"."

"Yes, I will talk to the bank about the loan today."

He Yu was silent for a long time, and finally agreed to purchase with a loan.

According to the technology and turnover shown by Yifei.

There are not too many bank managers who come to ask for loans these days, the leather shoes almost polished the floor of Yi Fei.

It's just that there is a super-high-margin product called a space engine.

Even if Tianyifei is buying companies frantically and deploying in the battery production industry, the capital flow can keep up.

As a qualified manager, facing such a good cash flow, she wanted to control the company's debt and leverage and minimize loans.

Unexpectedly, after being in control for so long and rejecting a bunch of bank clerks, Yifei still couldn't avoid the loan.

Moreover, the reason for the loan was that the boss suddenly had an idea that needed to be verified by the supercomputer, and he also bluntly stated that it might cause damage to the supercomputer.

It's just such a result, and Chen Yi's way of playing with hundreds of millions of supercomputers as toys, which made her feel tired.

Although she came to Yifei as a professional manager, she valued Yifei's technical potential.

But I didn't expect that Yifei's skills are really awesome.

The boss's unreliability is directly proportional to the level of the shopkeeper and Yi Fei's potential.

He Yu sighed inwardly, and asked again: "Mr. Chen, the company's battery production workshop will be remodeled in the near future, and trial production can be carried out. We are just waiting for your ultra-high-energy battery."

The cake Chen Yi drew for her before.

She had been injected with chicken blood and ate it with a groan.

Now, it's up to Chen Yi to fulfill his promise.
