Chapter 295 You are here just in time
Gao Zhendong came back from the National Defense Work Committee and was still working on the single-board computer. The results are about to come out. No one can resist it. I believe those who have done the project Everyone has this experience.
More than a day later, Wednesday afternoon, seeing "NiHao, ShiJie!" appearing on the monitor, Gao Zhendong slapped the table and shouted softly: "Come on!"
The Chinese character environment was ready to be handed over to People from the Computing Institute do it, so only Hanyu Pinyin can be used here.
He excitedly went to make a call, but someone from the factory office came over and brought a few people with him, saying that someone was looking for him.
Gao Zhendong took a closer look and found out that it was Mr. Cai who had been here last time, the one who worked on the Sky Monkey liquid rocket engine over in the desert.
But this time, he also brought someone with him.
Gao Zhendong stretched out his hands: "Hello, Mr. Cai, what kind of wind has brought you here."
Mr. Cai almost blurted out the word "dongfeng", but he managed to hold it back , turned to smile and said: "This time, I came here specifically to visit you, Director Gao."
Gao Zhendong was a little surprised. Ordinarily, the liquid rocket engine related to him was the ones from last time. They have placed orders to grow materials, so what else can they ask me for?
He led the two of them to the sofa and sat down. While making tea, he asked: "Oh? If you have anything to say, just tell me."
Mr. Cai did not say it directly, but smiled: "I am doing I believe Director Gao can guess it with his ability."
Gao Zhendong smiled and said nothing, just nodded, surprised, what? Is this a showdown? Did the superiors allow it?
Seeing Gao Zhendong’s actions, Mr. Cai suddenly realized that he had guessed it and asked a question in his mind: "Director Gao, it seems that the last time he said in front of me that alcohol is volatile, so Did you do it on purpose?"
Gao Zhendong smiled and nodded again.
Mr. Cai laughed loudly. Sure enough, he guessed right. Director Gao is a wonderful person.
He didn't sell it anymore and revealed the answer directly: "That's right, Director Gao, we have obtained permission to communicate some of our work with you and see if we can get some help from you. . ”
This Gao Zhendong likes to hear it, but he doesn’t have to play riddles anymore. He is afraid of playing riddles with the people from the Guidance and Research Institute. Their matter is more important than that of the Guidance and Research Institute. Gao Zhendong I'm afraid that if I keep playing riddles, problems will arise due to incomplete information, which will delay the other party's work.
"Mr. Cai's words are serious. If there is anything I can do to help, let's communicate. But first, let's talk about it. I don't know much about rocket engines."
Lying down The design drawings of solid rocket motors for individual anti-tank missiles in his storage library said: Fuck you!
However, he was really not as familiar with liquid hair as solid hair. It would be an exaggeration to say that he didn't understand it.
Mr. Cai smiled and said: "Director Gao is modest, but this time, we are not here for the rocket engine, but for the guidance."
At this time, he turned his head and introduced that he was coming with him. Person: "This is our chief engineer of the guidance system, Chief Engineer Zhang."
Gao Zhendong quickly welcomed Chief Engineer Zhang: "Hello, Mr. Zhang, you can be regarded as having a professional job." "
The two of them didn't know much about Gao Zhendong. They were originally curious about what he studied and how he was engaged in both materials and computers.
Mr. Cai and Gao Zhendong were familiar with each other, so he asked directly and curiously: "Director Gao, what is your major? I think your achievements span a wide range of majors."
A major that must bring materials and computers together , then computational chemistry can barely be calculated, but at this time, there is no such major.
Gao Zhendong said: "Automation, I graduated from Wudaokou."
Mr. Zhang smiled: "So Director Gao and I are still alumni, hello, junior brother." He also graduated from Wudaokou, Although he was much older than Gao Zhendong, he recognized his junior brother immediately.
Gao Zhendong was also happy: "Hello, senior brother." It's not a bad idea to recognize a senior brother. If the situation were to change, maybe he would become a senior uncle and uncle now.
"Senior brother, you are from an automated background, but you can make such achievements in materials. You are a genius."
"A small achievement, a small achievement. Senior brother, what do you need to communicate this time?" The topic among several people was a row of egrets flying up into the sky - flying further and further away. Gao Zhendong quickly pulled back the conversation.
Mr. Zhang then remembered that he was here for business.
"Junior brother, you also know that we are making missiles. Missiles must be guided, otherwise they will become rockets."
That is, I understand, you guys The requirements for missiles have always been very high, and those that fail to meet certain requirements are rockets. A few decades later, if you have a guided missile with a range of 400 to 500 kilometers and a warhead of 500 kilograms, you still call it a rocket.
"Speaking of guidance, we originally used a method similar to an analog computer for guidance, but after seeing your DJS-59, we had a bold idea. We want to use your DJS-59 to replace the analog computer, and use I don’t need to explain the benefits of digital guidance. You are an expert and you know it.”
Gao Zhendong nodded: “Well, you use inertial navigation, right?” See Gao Zhendong. General Manager Zhang knows that he really understands the words "inertial navigation", which is even better and makes communication easier.
"Yes, how do you know?"
Gao Zhendong glanced at Mr. Cai: "From Mr. Cai's graphite throat lining, I I can probably deduce the specifications of the rocket engine. From that specification, I can roughly know the range. Judging from 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 good enough. It’s not broad enough, anyway, I can only think of this.”
Hiss~~~~~~Both Mr. Cai and Mr. Zhang took a deep breath. Is this guy from an intelligence background? Coupled with his excellent technique, he can perform almost exactly what he wants with just one throat lining.
Intelligence + technology, so terrifying!
"Junior brother is a great talent! Junior brother is a great talent!" Mr. Zhang spoke in a rather old-fashioned way. He probably came from a scholarly family. This is also a common phenomenon among top technical talents these days.
Gao Zhendong smiled again and said: "Moreover, I recently received a batch of processing requirements for tungsten-molybdenum alloy components. I roughly know the size in mind."
What this means is , I have seen the gas rudder you want me to make. I can estimate the size range of the nozzle and even the size range of the engine for the size of the gas rudder.
Mr. Zhang had nothing to say, he was all looked at.
"Well, indeed, we use inertial navigation. Our current problem is that although the DJS-59 is already very small, it is still a bit larger when used in our missiles. The main body plus the power supply , storage, the total volume is still not small.”
If the volume and weight are too large, then the benefits of replacing analog with digital will not be obvious, or the gain outweighs the loss. After all, the core of the inertial navigation system is the accuracy of the inertial platform. For pure inertial navigation, replacing analog with digital can only be said to be the icing on the cake rather than a timely help.
Mr. Zhang and his colleagues want to use digital computers more to prepare for future development and improvement. On the first-generation missiles, there is actually not much difference between analog and digital, because the inertial platform is just like that.
“So we hope that we can make some simplified adjustments to the DJS-59 to reduce its size to about one-third of its current size. We have tested that for our needs, the DJS-59 The computing power is overflowing, so even if its capacity is reduced, as long as the volume is reduced, it will be easier for us.”
When Gao Zhendong heard this, he couldn't help but glance in the direction of the computer room, "I'm going, you sent someone to keep an eye on me secretly, right?" I just finished the single board computer and you guys are here?
He stood up and said to Cai and Zhang: "Don't tell me, there happens to be such a thing. You came at the right time. Come with me, let's go to the computer room to have a look."
< br>Cai and Zhang were overjoyed. This young man became a spirit in the wishing pond, right? What you want is what you want?
The two followed Gao Zhendong to the computer room.
What came into view was a DJS-59 with many devices connected to it. They all knew it, except for the printer, because this product had not yet been mass-produced and shipped.
"Director Gao, is this the DJS-59?" Mr. Cai hesitated. This is similar to the one we have over there, except it has more peripherals.
Gao Zhendong shook his head: "It's not the big one, over there."
After speaking, he stretched out his finger. Cai and Zhang looked along his finger and found that there was a I bought a circuit board, just a single one, and it also had a lot of wires connected to it.
The circuit board looks a bit like one of the DJS-59 systems. It is about the same size, but the electronic components on it are obviously different. They are small plastic squares.
“Is this a new part of DJS-59?” Chief Zhang, who is more familiar with electronics, asked.
Gao Zhendong shook his head: "No, this is the DJS-59, or in other words, its capabilities are similar to the DJS-59 at the back, except that the storage is smaller."
The two were shocked when they heard this. : "You mean that such a small circuit board can complete the same work as DJS-59? Except that the storage is smaller."
For them, there is no need for such a large storage , after all, the guidance system does not need an interface, does not need to handle other affairs, does not need peripherals, and does not need remote communication. It just receives the data from the inertial navigation platform, performs fixed algorithm calculations, and then outputs the results.
Gao Zhendong nodded: "So I say you are here at a good time. I just finished the debugging today. It took me several months of effort. It was quite difficult."
Mr. Zhang The teacher had the urge to kick him. Who taught this junior brother? He was really too much to be beaten.
Gao Zhendong pointed to "NiHao, ShiJie!" on the monitor and asked Master Zhang: "Brother, you should be familiar with this. It was just compiled and ran out, just a few minutes before you came to me."
< br>Since the advent of DJS-59, everyone who works on computers knows this sentence, and Mr. Zhang is no exception. He knows that this proves that this computer can at least work normally.
General Master Zhang was struck down by happiness. He originally came here just to communicate, mention his needs, and see if there was any hope in a short time.
Unexpectedly, Gao Zhendong had already cushioned the pillows before he felt sleepy.
