Build a photolithography machine? No, my photolithography park, photolithography factory

Lin Fan once had a luxury sports car, but after his father died, he sold it.

He didn't drive it a few times.

Sports cars, not so fun, most of them are driven out for face, and every time they are driven, the price is very expensive.

Now looking at this group of rich second generations, Lin Fan felt a little emotion in his heart.

During this time, this group of rich second-generation people seemed to be blowing up streets around here.

It seems that because at two o'clock in the morning, there are not many cars here, it is relatively quiet, and they often get together to play, which is very disturbing.

In the distance, Lin Fan saw two familiar faces inside, it was the sons of his second and third uncles, that is, his cousins Zhou Yao and Zhou Hao...

They each seemed to be holding a girl with long flowing hair and playing with everyone.

They are now... It can also be regarded as the rich second generation.

Lin Fan didn't bother to pay attention to them, and took his things and walked towards the house.

The company needs to do UAVs, naturally it will not be an ordinary UAV.

Lin Fan's engine is called the miniature turbo engine, which is a multi-cylinder turbocharged engine developed based on the alien toys he found.

This engine is still 108,000 miles away from alien technology, but it is relatively advanced compared to Earth.

For example, it is stable, has little fluctuation, low energy consumption, low wear, fast speed, and is an adaptive variable cycle engine.

This is what Lin Fan improved on the basis of the earth, and it is already quite reliable.

Lin Fan did not make it bigger, because he did not have this qualification, he just wanted to make a drone first for the time being to see the effect of the drone.

What is an adaptive variable cycle engine?

Generally speaking, the engine structure is from front to rear: intake port - compressor - combustion chamber - turbine - nozzle.

The corresponding process is air inhalation - air compression and pressurization - air mixed combustion - drive the turbine to rotate - tail ejection to do work.

The variable cycle engine, on the other hand, adopts a turbofan system that divides the air flow into three ducts, but these three ducts can be changed in size and caliber and combined to form the best working mode.

That is, it can change automatically.

When economical cruising is required, 2 control plates adjust downwards to block the air flow through the combustion chamber and allow the engine to operate in turbofan mode.

When transonic maneuvering is required, the adjustment plate 1 is down, 2 up, forming a turbojet engine.

When supersonic cruising is to be carried out, adjustment plates 1 and 2 are deflected upwards, making it a ramjet engine.

If the engine uses a mission planning system, you can also use computers to plan the operation mode of the engine according to different tasks to achieve the best combat efficiency.

This measure may seem simple, but it is very difficult to implement in engineering.

Because the engine works under the condition of high temperature and high pressure and extremely high speed, it is best not to have any structural changes, otherwise, it will bring disastrous consequences.

Any damage to engine components can lead to engine safety issues.

If the baffle is offset, it will also bring about instantaneous distortion of the airflow, resulting in unstable engine operation and even shutdown.

So, such an engine is very difficult to manufacture!

And Lin Fan's adaptive variable cycle engine has perfectly solved this problem!

Anyway, he has money in his hands, and this money cannot be kept, part of the bank loan is repaid, and the rest is used as a reserve fund.

Lin Fan decided to spare 50 million to develop a new type of drone.

Fighters, he did not dare to develop, did not have this qualification.

However, fighter models, he can be developed, just treat fighters as drones, as models to develop.

Therefore, after returning to the company, Lin Fan quickly explained the matter of the light factory.

The light factory is still in production and has been on track, and the chips supplied to companies such as Warwick Technology are estimated to be completed in two months.

At this time, Lin Fan found Xu Lei to discuss with Old Song Tou.

Lao Song Tou is the technical director, a doctor of optics and mechanics, and one of the technical backbones of the light factory.

And Xu Lei, from the beginning, he followed Lin Fan to start a business together, loyal, also a doctor of optics, Lin Fan trusted him.

Lin Fan said: "Now that the company has money, there are still more than a billion funds on the books, and there should be no shortage of orders in the follow-up!

"Trivial trifles?"

"This is..." Xu Lei and Old Song Tou were surprised, looking at the documents on the table.

It depicts an engine and an airplane.

"It's a model machine, of course, a toy drone, it's not a propeller plane, but it has very strong stability. I'm going to put new engines and sensors on them so that they don't fall to the ground and are easy to handle!"

Lin Fan calmly explained: "Even, I plan to let them hover in the air and take off and land vertically, similar to the Harrier fighter!"

When Xu Lei and Old Song Tou heard this, they were immediately stunned.

Blinked, a little confused.

Old Song Tou immediately said: "When our light factory is making money, we should increase our horsepower and continue to make money, Mr. Lin, why do you want to make this? Is it feasible?"

"This drone, it really seems like a joke, but it is also a model machine, a toy machine, vertical take-off and landing, hovering in the air?

Lin Fan shook his head: "The speed of the propeller is limited, it's not something I want to do!

"What do you want to do at that speed?" said the old Song Tou, "This is just a toy machine! Mr. Lin, you're not doing your job!"

Lin Fan looked at him and smiled: "Old Song Tou, don't worry first! The light factory is naturally still our main business! It's just that our research and development has come to an end, and we only need production in the future, no research and development is required, so we need to develop new things!

Old Song Tou cried and laughed: "Then you can't do this! This looks completely out of line! A toy machine, but also vertical take-off and landing, hovering in the air, that should indeed be equipped with propellers!"

Lin Fan suddenly smiled slightly and did not speak.

Old Song was stunned, not knowing what he meant, and hurriedly continued to read the document.

Xu Lei also looked down and immediately stared at the engine above.

"This is..."

Old Song Tou was surprised: "Multi-cylinder turbocharged engine?"

Lin Fan smiled slightly: "Anyway, it's just a trivial matter, it doesn't cost much, let's study it!"

“......"
