"We now have a small bench No. 1, on the basis of the small bench, simplified a skeleton, this can't be done? If this can't be done, hehehehe......"

Lu Rongrong was so red from Chen Haocong's laughter that he waved his fist and was about to hit him. Pen % fun % Pavilion www.biquge.info

He Cunping grabbed him and said, "Fluffy, in fact, I think Cong Cong is right." ”

"Even if it's right, I'm very upset with his tone and hit him!"

"That's right, this tone makes me very upset!

Lu Rongrong and He Cunping were two-on-one, beat Chen Haocong violently, and then walked away.

Chen Haocong finally struggled to get up, and cried with two dark circles under his eyes and asked Wang Shihao, who was watching the excitement next to him: "Brother Hao, why is it that if you say the same thing, Uncle Ming won't be beaten when he speaks, but if I say it, he will be beaten?"

Wang Shihao thought about it carefully and said, "Probably because when your uncle said this, he brought bodyguards with him?"

Chen Haocong was dumbfounded, thinking about Zhao Xiaopang, who was standing beside Nanming at that time, and felt that it was so reasonable, and he couldn't refute it at all.

"The next time I pretend to be a force, I must remember to bring a bodyguard. Chen Haocong took out a small notebook and wrote down this sentence.

This is a lesson of blood and tears!

In the past, Chen Haocong never used low-end things like "small books".

And now, his PU leather notebook, which he bought from the gate of Zhaoxian Primary School for less than five yuan, has reversed the situation and densely written countless ideas.

He found that sometimes it was unexpected, and that there were several design problems that had come together from his ideas.

After he wrote down this sentence, he flipped through the notebook, and ran to drag Liu Tianyun and said, "Brother Tianyun, where did you just go? Let's go on." ”

Liu Tianyun looked at Chen Haocong's dark circles, saw that he didn't care, and couldn't help but shake his head, a bear child is a bear child.

It's just a punch, and it really doesn't matter, so he said: "I just talked about high-end aerospace-grade FPGAs, and now that we have an engine, we will use the engine design of the Silence...... I'm trying to get the early design drawings out as soon as possible, but I'm afraid there are no FPGAs that work right now, and we have to find a way to simplify the engine. ”

The so-called FPGA is a "field programmable gate array".

To put it more simply, it's the brain of a rocket.

So far, they have confirmed the mechanical design of the engine, using the rocket engine that Chen Haocong picked from the Silence.

The Silence's engine, in fact, is essentially a fusion rocket engine, burning metallic hydrogen is only its auxiliary function, in addition to nuclear fusion heating air, magnetic field spraying ionized air, two auxiliary propulsion methods, to deal with more complex environments, such as taking off from underwater, at very high altitude, or if a certain mode of operation fails.

At the beginning, Feng Tianyou said that the engine of the Silence was very simple, but in fact, it was simply complex and extremely powerful, okay?

At the beginning of the design of the Silence, Nan Ming and others had already set aside a margin in the design, which made Chen Haocong see his own shortcomings and sigh for a long time.

However, the result of the Silence's high-end engine is that the simplified castration version is too complicated, and the existing FPGA is simply not up to the task of controlling this complex engine.

Aerospace-grade FPGAs are much more demanding than civilian ones.

It has to operate normally under ultra-high temperature, ultra-low temperature, high pressure, low pressure, ultra-high speed, and ultra-high acceleration, and it also has to monitor various data of the rocket in real time, communicate with the ground, and so on......

The reliability requirements are simply too high.

Aerospace electronic components are the eternal pain of our rabbit aerospace industry.

Internationally, the most high-end aerospace-grade PFGAs are all from the United States.

The giants of field-programmable logic gate arrays, such as Actel, Altera, Xilinx, and Lattice, all belong to the United States without exception...... That's what America is all about.

In my rabbit's aerospace components recommendation manual, the recommended high-end aerospace-grade FPGA is ACTel's APA1000, but this is only Actel's product around 2000, that is, more than ten years ago. In the past decade or so, the capacity and speed of FPGAs have changed dramatically, and performance has skyrocketed.

Without the support of such high-performance chips, it would not be possible to have a recyclable rocket from SpaceX company Ma Yilong. Ma Yilong's Falcon rocket can automatically land vertically to the designated place after liftoff, and the detached first-stage rocket can be automatically recovered -- although the success rate is not high.

However, these high-end aerospace FPGAs that can handle such complex operations are completely prohibited from export, and they cannot be bought at all.

Although we have made remarkable achievements in aerospace and space exploration over the years, in the field of aerospace electronics, we have always been picking up American bread crumbs to eat.

Whenever he thinks of his motherland, he has to follow behind the Yankees with his head held high, bow humbly, and shout: "Sir, have mercy on me, give me a bite of bread crumbs to eat." Liu Tianyun and Mr. Wu were both humiliated and heartbroken in their hearts.

Chen Haocong didn't understand the pain in this, nor could he understand the feelings of Liu Tianyun and Mr. Wu, he said: "Simplification is not necessarily a regression, the simpler the more reliable, this is what Uncle Ming taught me." ”

As a "body" engine, the simpler and more straightforward it is, the more reliable it is.

As the "brain" of the FPGA, the more powerful, efficient, and reliable it is.

Small horses and large carts are easy to drag and not move, but large horses and small carts are nine out of ten.

No one in this world can conquer the world, and Nanming's enhancement ability is not omnipotent, it can't be pointed to where to fight, and it will often be strengthened to be completely useless, otherwise it will not be full of all kinds of strange technologies now, even the technology of mecha gods.

At the same time, it will also leave a large blank in the place where it is needed, and these gaps may only be needed in a very small part, which is not worth special strengthening, and can only be studied by yourself to make up for the shortcomings.

"Uncle Hades, when they designed the Silence, there were many technical problems that couldn't be solved, if it was Uncle Hades, what would they do?"

Chen Haocong unconsciously substituted himself into the role of Nanming.

For example, to make the Silence fly, at first the weight and resistance of the Silence was still too great to take off by taxiing on the water, so Nanming and the others used a smarter and simpler way to bypass this stage, that is, a huge artificial spider silk air sac.

Using air buoyancy, the Silence was pulled up from the water and accelerated to a sufficient speed before the airbag was discarded and replaced with aerodynamic flight.

Even so, it still created the legend of the first epic journey, is this a stain on the lazy god system?

Of course not!

Later, when the second epic journey was approaching, the Silence finally made up for this shortcoming, and could glide directly on the surface and take off.

There is no clue about improving the FPGA, and Chen Haocong plans to start by simplifying the engine.

The rocket engine of the Silence burns metallic hydrogen, which is enough to react with the air in the atmosphere, but if it flies outside the atmosphere, liquid oxygen is added......

Hydrogenium...... Liquid oxygen? and so on!

An idea suddenly flashed through Chen Haocong's mind. (To be continued.) )
