Chapter 295 You Came at the Right Time
Gao Zhendong was still working on the single-board computer after returning from the Defense Work Committee. It seemed that the results were about to come out, and no one could help themselves. I believe that everyone who has worked on the project has this experience.

More than a day passed, on Wednesday afternoon, when Gao Zhendong saw the words "Ni Hao, Shi Jie!" appear on the monitor, he slammed the table and shouted, "Enough!"

The Chinese character environment is going to be handed over to the people in the computing institute, so only Pinyin can be used here.

He was about to make a phone call excitedly, but someone from the factory office came over with a few people and said someone was looking for him.

Gao Zhendong looked carefully and found that it was Mr. Cai who had been here last time, the one who was working on the liquid rocket engine for the Skyrocket in the desert.

But this time, he brought someone with him.

Gao Zhendong stretched out his hands and said, "Hello, Mr. Cai. What brings you here?"

President Cai almost blurted out the word "Dongfeng", but managed to hold it back, and said with a smile: "This time, I came here specifically to visit Director Gao."

Gao Zhendong was a little surprised. Normally, the liquid rocket engine that had anything to do with him were only the few materials from last time. They had already placed the order, so what else could they come to him for?

He led the two of them to sit on the sofa, and while making tea, he asked, "Oh? If you have anything to say, just tell me."

Mr. Cai did not answer directly, but smiled and said, "What I do, I believe with Director Gao's ability, he should be able to guess it."

Gao Zhendong smiled but didn't say anything. He just nodded, wondering, what? Is this a showdown? Has the higher-ups given the go-ahead?
When President Cai saw Gao Zhendong's actions, he suddenly realized that he had guessed it, and asked a question in his mind: "Director Gao, it seems that you said in front of me last time that alcohol is volatile, and you did it on purpose?"

Gao Zhendong smiled and nodded again.

Mr. Cai laughed out loud, he was right, Director Gao was a wonderful person.

He didn't keep the secret any longer and revealed the answer directly: "This is it, Director Gao, we have obtained permission to communicate some of our work with you to see if we can get some help from you."

Gao Zhendong liked to hear this. Finally, he didn't have to play charades. He was tired of playing charades with those people from the Institute of Guidance and Research. Their matter was more important than that of the Institute of Guidance and Research. Gao Zhendong was afraid that if he kept playing charades, problems would arise due to incomplete information, thus delaying the other party's work.

"Mr. Cai, you are too polite. If there is anything I can help you with, let's talk. But first, let me make it clear that I don't know much about rocket engines."

The design drawings of the solid rocket engine for the individual anti-tank missile lying in his storage warehouse said: You are bullshitting!
However, he is not as familiar with liquid hair treatment as solid hair treatment, so it is not an exaggeration to say that he does not understand it.

President Cai smiled and said, "Director Gao is modest, but this time I am not here for the rocket engine, but for the guidance."

Only then did he turn around and introduce the person who came with him: "This is our guidance system chief engineer, Chief Engineer Zhang."

Gao Zhendong immediately welcomed Chief Engineer Zhang: "Hello, Chief Engineer Zhang. I finally have a job in my field."

The two did not know much about Gao Zhendong's situation and were curious about what he studied and how he was involved in both materials and computers.

Mr. Cai was a little familiar with Gao Zhendong, so he asked out of curiosity, "What is Director Gao's major? I see that your research achievements cover a wide range of fields."

If we must have a major that combines materials and computers, then computational chemistry can barely be considered one, but at this time, there is no such major.

Gao Zhendong said: "Automation, graduated from Wudaokou."

Mr. Zhang smiled and said, "So Director Gao and I are alumni. Hello, junior brother." He also graduated from Wudaokou University. Although he is much older than Gao Zhendong, he immediately recognized him as his junior brother.

Gao Zhendong was also happy: "Hello, senior brother." It's not a bad thing to have a senior brother. If it were in a different situation, maybe they would become uncles or aunts.

"Junior brother, you are originally from the field of automation, but you have made such achievements in materials. You are a genius."

"A small achievement, a small achievement. Senior brother, is there anything you need to communicate this time?" Seeing that the topic of several people was a group of egrets flying farther and farther into the sky, Gao Zhendong quickly took the subject back.

Mr. Zhang then remembered that he had come here for important business.

"Junior brother, you know that we make missiles. Missiles must be guided, otherwise they will become rockets."

That is, I understand, you have always had high requirements for missiles, and anything that does not meet certain requirements is a rocket. Decades later, guided missiles with a range of 500 to kilometers and a warhead of kilograms are still called rockets.

"Speaking of guidance, we originally used a method similar to analog computers for guidance, but after seeing your DJS-59, we had a bold idea. We want to use your DJS-59 to replace analog computers and use digital guidance. I don't need to explain the benefits, you are an expert, you know it."

Gao Zhendong nodded: "Well, you are using inertial navigation, right?" Seeing that Gao Zhendong could say the words "inertial navigation", Chief Engineer Zhang knew that he really understood it, which was even better, and communication would be easier.

"Yes, how do you know?"

Gao Zhendong glanced at Mr. Cai and said, "From the graphite throat liner Mr. Cai has, I can roughly deduce the specifications of the rocket engine. From that specification, I can roughly know the range. Based on the range and existing technical conditions, I can't think of anything else except inertial navigation. Maybe my skills are not good enough, and my experience is not broad enough. Anyway, this is all I can think of."

Hiss~~~~~~Boss Cai and Boss Zhang both took a deep breath. Is this guy from the intelligence field? Plus, he has excellent skills. He can make a pretty accurate guess based on a throat lining.

Intelligence + technology, so terrifying!
"Junior brother, you are so talented! Junior brother, you are so talented!" Mr. Zhang spoke in a rather ancient style. He was probably from a scholarly family. This is also a common phenomenon among top technical talents these days.

Gao Zhendong smiled again and said, "Besides, I recently received a request for processing a batch of tungsten-molybdenum alloy components, and I have a rough idea of ​​the size."

What I mean is that I have looked at the gas rudder you want me to make, and I can deduce the size range of the nozzle and even the size range of the engine based on the size of the gas rudder.

Mr. Zhang had nothing to say, everything was seen.

"Yes, indeed. We use inertial navigation. Our problem now is that although the DJS-59 is already very small, it is still a bit large for use on our missiles. The main body plus the power supply and storage, the total volume is still not small."

If the size and weight are too large, the benefits of changing from analog to digital will not be obvious, or it may be said that the gains do not outweigh the losses. After all, the core of the inertial navigation system is the accuracy of the inertial platform. For pure inertial navigation, changing from analog to digital can only be icing on the cake rather than timely help.

Mr. Zhang and his colleagues want to use digital computers more to prepare for future development and improvement. In the first generation of missiles, there is actually not much difference between analog and digital, because the inertial platform is like that.

"So we hope to make some simplified adjustments to the DJS-59 and reduce its size to about one-third of its current size. We have tested that the computing power of the DJS-59 exceeds our needs, so even if we reduce its capacity, as long as its size is reduced, it will be easy for us."

Hearing this, Gao Zhendong couldn't help but glance in the direction of the computer room. Oh my god, you sent someone to secretly watch me, right? I just made the single board computer, and you guys came?

He stood up and said to Cai and Zhang, "You're right, there's just such a thing. You came at the right time. Come with me, let's go to the computer room and take a look."

Cai and Zhang were overjoyed. Is this guy a spirit from the wishing well? He can get whatever he wants?
The two followed Gao Zhendong to the computer room.

What caught their eyes was a DJS-59, which had many devices connected to it. They all recognized them, except for the printer, because this product had not yet been mass-produced and shipped.

"Director Gao, is this DJS-59?" Mr. Cai hesitated. Isn't this similar to the one we have, except that it has more peripherals?

Gao Zhendong shook his head: "Not the big one, it's over there."

After he finished speaking, he pointed with his finger. Cai and Zhang looked in the direction where his finger pointed and found a circuit board on the table, just a single one with a lot of wires connected to it.

The circuit board looks a bit like one of the ones in the DJS-59 system. It is about the same size, but the electronic components on it are obviously different. They are small plastic cubes.

"Is this a new component for DJS-59?" Chief Engineer Zhang, who was more familiar with electronics, asked.

Gao Zhendong shook his head: "No, this is the DJS-59. In other words, its capabilities are similar to the DJS-59 behind it, except that it has less storage."

The two were shocked when they heard this: "You mean this small circuit board can do the same job as the DJS-59? Except the storage is smaller."

For them, there is no need for such a large storage. After all, the guidance system does not require an interface, does not need to handle other matters, does not need peripherals, and does not require remote communication. It simply receives data from the inertial navigation platform, performs fixed algorithm calculations, and then outputs the results.

Gao Zhendong nodded: "That's why I said you guys came at the right time. I just debugged it today. It took me several months to debug it. It was quite difficult."

Chief Engineer Zhang had an urge to kick him. Who taught this junior fellow? He really deserves a beating.

Gao Zhendong pointed at the “Ni Hao, Shi Jie!” on the monitor and asked Chief Engineer Zhang: “Brother, you should be very familiar with this. It was just compiled and run a few minutes before you came to me.”

Since the DJS-59 came out, everyone who works with computers knows this, and Chief Engineer Zhang is no exception. He knows that this proves that the computer can at least work properly.

Chief Engineer Zhang was suddenly overwhelmed by happiness. He had originally come here just to communicate, raise requirements, and see if there was any hope in the short term.

But I didn't expect that Gao Zhendong had already put the pillow in place before I even fell asleep.
