Compare to the previous chemical-fuel-propelled drones.

There is already mature technology on the market, and there are mature accessories.

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

Now the ion propulsion drone, the Hall propulsion drone, this is a breakthrough from scratch.

This represents.

The overall system design and accessories of the ion propulsion drone, including each technology, must be studied by Chen Yi himself.

For this.

Chen Yi spent more than half a month.

I asked Professor Zhang for a list of relevant books and literature.

Consume two opportunities for virtual learning.

Only then did he complete the design and planning of his new drone.

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

Towards a new milestone in the development of machines.

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

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

"For the same power, the faster the jet speed and the higher the impulse, the lower the mass of the jet and the less thrust."

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

"One is that the thrust is adjustable, and the air can be intaken at low altitudes.

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

The third is the lightweight and hollowing of the material structure to reduce the weight of the fuselage itself.

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

The image point describes that ion propulsion plays with long-lasting technology, and there are external supplements.

You can't be as energetic, red-hot, and violent-...... as young as chemistry."

Chen Yi was clear about his thinking step by step.

In the past half month, except for the fifteenth day of the lunar calendar a few days ago, the moon landing drone that has entered the lunar orbit has been controlled, and a close-up moon has been filmed and a dynamic has been posted, and no live broadcast has been kept low-key.

He also took the time to build a rotary detonation engine, read the technology, and made a technical paper to send to Professor Zhang.

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

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

Take, for example, the HET-80 Hall thruster on the Tianhe space station.

The power is 1350W, which is equivalent to 1.8 hp, but the HET-80 produces only 80 milliN of thrust.

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

6 HET-80 Hall thrusters to propel an egg.

Such an ion-propelled drone, you can imagine how small the thrust is.

If you want to go into space on the ground, you have to use different designs and technologies.

"After the hardware system design is completed, the next step is the design ...... the avionics control plane"

Chen Yi took out his mobile phone and dialed He Yu's number.

Space drones do not go to orbit.

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

In this way, before the drone is made, artificial intelligence also needs to be arranged.

"Hey, Mr. He.

Recently, there was a new idea, and the studio wanted to order a supercomputer.

The cost of supercomputing will be deducted from the studio's patent authorization fee in the future. ”

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

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

Now Yifei has completed the industrial and commercial restructuring.

The entire wing flight is divided into two parts.

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

The other part is the new company of Yifei managed by He Yu, which is responsible for the operation of the market, production, sales, etc., and everything except technology development.

The technology of Yifei is authorized by agents.

Authorized by Wingfly Studio, it is handed over to Wingfly Company as a full agent.

Wing Fly New Company.

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

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

See the company's most recent sales totals, as well as the total amount of scheduled orders.

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

"About 100 million."

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

“......”

Hearing this price, He Yu's expression almost didn't collapse: "Mr. Chen, there are less than 50 million left in the company's account, your supercalculation, the price is too high." ”

"No, I think the drone engine has been bought very well recently.

The shipment volume exceeded 20,000, even if it was calculated at a wholesale price of 25,000, which would be at least 500 million. ”

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

For the drone engine he researched, he knows very well how much it costs.

In the past, the small workshop of Yifei made an engine with a cost of between 2000 and 2500 yuan, counting raw materials, labor, equipment loss, positioning chips, electricity costs, etc.

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

More than 80% of the 500 million yuan of shipments are profits.

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

“......”

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

Yifei acquired a battery manufacturing company for 256 million.

Recently, the battery production workshop was renovated, and various materials and equipment were booked, which cost 89 million.

Plus a few others relocated company headquarters, acquired labs, and more.

I have reported to you all these large expenditures of more than two million, and the cashier form has also been sent to Manager Qin, so that she can sign it for you.

Do you want to sign without even looking at it? ”

"Really?"

Chen Yi thought for a moment.

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

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

Chen Yi opened his company's mailbox to check the latest financial summary sent by the finance.

When we see the debt ratio of Yifei, it is less than 10%.

This He Yu is still too conservative.

With such a low debt ratio, not enough money to take out a loan?

Thinking of this, Chen Yi made a decision: "Mr. He, take out a loan to order one first, and put it in the name of the assets of the company."

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

"I would venture to ask, what does Mr. Chen plan to do when he buys this supercomputer, and is the company going to develop new business in the data computing industry recently?"

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

"Suddenly I had an idea that I needed to use a supercomputer to validate." Chen Yi did not hide it, and replied very simply.

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

"The experiment is more violent, which may lead to damage to the supercomputer, so buy it yourself."

“......”

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

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

In accordance with the technology and turnover of the performance of the wingflight.

These days, the bank manager who comes to ask for a loan is simply not too much, and the leather shoes are almost polishing the floor of Yifei.

It's just that there is a space engine, a super high-profit product.

Even if Yifei is crazy about acquiring companies and laying out the battery production industry these days, the capital flow can keep up.

As a qualified manager, in the face of such a good flow of funds, she wants to control the company's liabilities and leverage, and try to borrow as little as possible.

I didn't expect to control it for so long and reject a bunch of bank clerks, but Yifei still couldn't avoid loans.

And the reason for the loan is that the boss suddenly has an idea that needs to be verified by the supercomputer, and he bluntly said that it may lead to supercomputer damage......

It's just that this result, as well as Chen Yi's gameplay of using hundreds of millions of supercomputers as toys, makes her feel tired.

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

But I didn't expect that Yifei's technology is really awesome.

The unreliability of this boss is directly proportional to the degree of hands-off shopkeeper, and also proportional to the potential of Yifei.

He Yu sighed in his heart, and asked: "Mr. Chen, the company's battery production workshop will be transformed in the near future, and trial production can be carried out, just waiting for your ultra-high-energy battery." ”

The cake that Chen Yi painted for her before.

She had already been beaten with chicken blood and ate it with a scream.

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