Compared with previous chemical fuel-propelled drones.
There are already mature technologies and mature accessories on the market.
Chen Yi only needs to buy accessories, assemble them manually, and then adjust the attributes and upgrade them.
The current ion propulsion drones and Hall propulsion drones are breakthroughs from scratch.
This represents.
The overall system design, accessories, and every technology of the ion propulsion drone must be researched by Chen Yi himself.
to this end.
Chen Yi spent more than half a month.
I asked Professor Zhang for a list of relevant books and documents.
Consume two virtual learning opportunities.
Only then did he complete the design and planning of his new drone.
At the same time, this is also his first self-designed drone.
Towards a new milestone in machine development.
“Although the efficiency and specific impulse of ion thrusters are very impressive, their thrust is notoriously small.”
"In addition, it can be calculated based on the conservation of kinetic energy and the impulse formula."
"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 use ion propulsion to enter space from the ground, four key points are inseparable."
“One is that the thrust is adjustable and air can be taken in at low altitudes.
The second is to increase the energy density, so that the same mass releases higher energy.
The third is to make the material structure lighter and hollower to reduce the load on the fuselage itself.
The fourth is to enter space by only overcoming the gravity of the planet and using low-speed spaceflight.
To describe it vividly, ion propulsion is about long-lasting technology and external supplements.
It cannot be as energetic, prosperous, and violent as a young person like chemical propulsion..."
Chen Yi clarified his thoughts step by step.
In the past half month, except for a few days ago on the 15th day of the lunar calendar, I controlled the lunar landing drone that had entered the lunar orbit, took a close-up view of the moon and posted an update, and did not broadcast any more live broadcasts to keep a low profile.
I also took the time to build a rotary detonation engine, and wrote a technical paper on reading technology and sent it to Professor Zhang.
The rest of the time, Chen Yi was busy with the technical details of the new drone.
The biggest drawback of ion propulsion is that the thrust is too small.
Take the HET-80 Hall thruster of the 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.
It takes 6 HET-80 Hall thrusters to push one egg.
One can imagine how small the thrust of such an ion-propelled drone is.
If you want to enter space from the ground, you must use different design and technical means.
"The hardware system design is completed, and the next step is the design of the avionics control level..."
Chen Yi took out his mobile phone and dialed He Yu's number.
Space drones do not follow orbits.
The avionics control system is inseparable from the assistance of artificial intelligence.
In this way, artificial intelligence also needs to be arranged before manufacturing drones.
"Hey, Mr. He.
Recently, I have a new idea. The studio wants to order a supercomputer.
The super-computing fee will be deducted from the studio’s patent licensing fee 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 its industrial and commercial restructuring.
The entire Yi Fei is divided into two parts.
Part of it is Chen Yi's studio and the laboratory he is acquiring, which are responsible for technology development.
The other part is the Yifei New Company managed by He Yu, which is responsible for market operations, production, sales, etc., and all matters except technology development.
Yifei's technology is licensed through agents.
Authorized by Yifei Studio and handed over to Yifei Company as the sole agent.
Yifei New Company.
He Yu is following up on the renovation and construction of the factory and handling company affairs.
After hearing Chen Yi's request, he subconsciously opened the report.
View your company's recent sales totals, as well as pre-order totals.
After looking at it, He Yu replied to Chen Yi: "Mr. Chen, what is the approximate 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 collapsed: "Mr. Chen, there is less than 50 million left in the company's account. You have calculated that the price is too high."
"No, I think the recent purchase of drone engines is quite good.
The shipment volume exceeded 20,000. Even based on the wholesale price of 25,000, the revenue was at least 500 million. "
A trace of doubt flashed in Chen Yi's heart.
Regarding the drone engine he developed, he knew exactly how much it cost.
In the previous small workshop of Yifei, the cost of manufacturing an engine was between 2,000 and 2,500, including raw materials, labor, equipment losses, positioning chips, electricity bills, etc.
Now that Yifei has acquired a larger and better-equipped mechanical processing factory, the total production capacity has been increased to 50,000 per month. The manufacturing cost of this engine can be further reduced, conservatively to less than 2,000.
More than 80% of the 500 million payment for shipments is profit.
But now, He Yu says that Yifei can'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 for 256 million.
The battery production workshop was recently renovated and various materials and equipment were ordered at a cost of 89 million.
Plus a number of other relocations of corporate headquarters, acquisition of laboratories, and more.
I have reported all these large expenditures exceeding two million to you, and the cashier's slip has been given to Manager Qin for her to bring to you for signature.
You couldn't have signed it without even looking at it, right? "
"Yeah?"
Chen Yi thought for a moment.
It seems that a few days ago, Qin Xiaoyu did bring some financial statements for him to sign.
However, he was busy designing his new drone at the time, and almost forgot about it after signing the contract.
Chen Yi opened his company email and checked the latest financial summary sent by the finance department.
When I saw Yifei's debt ratio, it was less than 10%.
This He Yu is still too conservative.
With such a low debt ratio, you don’t even have enough money to get a loan?
Thinking of this, Chen Yi made a decision: "Mr. He, first order a loan and put it in the name of Yifei Company's assets.
After the subsequent patent dividends are distributed, they will be transferred to the studio in the form of capital offset. "
"I would like to ask, what is Mr. Chen planning to do when he buys this supercomputer? 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.
"I suddenly had an inspired idea and I need to use a supercomputer to verify it." Chen Yi did not hide anything and answered simply.
"In this way, we can rent supercomputers and there is no need to spend so much money to buy them. Yifei's business does not need to use supercomputers for a long time yet."
"The test is relatively violent and may cause damage to the supercomputer. It is better to 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 the loan purchase.
According to Yifei's performance technology and turnover.
These days, there are not many bank managers who come to ask for loans, and their leather shoes are almost polishing the floor of Yi Fei.
However, there is the ultra-high-profit product called space engine.
Even though Tianyi Fei is crazy about acquiring companies and deploying in the battery production industry, its capital flow can keep up.
As a qualified manager, faced with such good capital flow, she wanted to control the company's liabilities and leverage and borrow as little as possible.
Unexpectedly, after being in control for so long and rejecting a lot 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 bluntly stated that it might cause damage to the supercomputer...
But this result, and Chen Yi's way of treating hundreds of millions of supercomputers as toys, made 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 Yi Fei's skills were really awesome.
The boss's unreliability is proportional to the degree of hand-off shopkeeper and Yi Fei's potential.
He Yu sighed inwardly and turned to ask: "Mr. Chen, the company's battery production workshop will be renovated in the near future and can be put into trial production. We are waiting for your ultra-high-energy batteries."
The cake that Chen Yi drew for her before.
She had already injected chicken blood and slurped it up as she ate it.
Now, just wait for Chen Yi to fulfill his promise.
