Siheyuan Great Craftsmen

He had never expected that the current domestic electronic development was so rudimentary, almost zero, and even qualified electronic vacuum tubes were hard to find. If it weren't for the strong support of the military, it would have been a pipe dream to successfully develop this CNC three-axis lathe.

Although lathes have been produced, their performance is far from what he expected. Compared with the CNC lathes presented in the virtual space of his mind, they seem to be from two completely different eras.

After visiting the underground laboratory, Zhou Tian and several military missile experts began to study Big Brother's Sa-1 anti-aircraft missile.

After this period of hard work, the design of the Sa-1 anti-aircraft missile has been completed. Of course, while the design of the Sa-1 is being completed, the design of the Sa-2 is also halfway through.

It's not that he didn't want to do it all at once, but given that they had just started researching air-to-air missiles, if they took out the Sa-2 all at once, he was afraid that several missile experts would not be able to keep up with the idea.

Therefore, Zhou Tiancai plans to study Sa 1 from the beginning, so that they can gradually adapt.

Anti-aircraft missiles are missile systems specifically designed to destroy enemy aircraft. They can be deployed on ground, sea or air platforms and can intercept fixed-wing aircraft, helicopters, cruise missiles and even ballistic missiles in all weather conditions.

The air defense missile system is usually composed of the missile body, launch device, radar and other sensors, command and control system, and support facilities. Its complexity is by no means comparable to that of light or heavy weapons.

To develop a successful air-to-air missile, we must first ensure the precision of its guidance system so that it can accurately track and intercept high-speed maneuvering air targets. This requires the guidance system to have extremely high accuracy and response speed.

For this reason, the design and optimization of the guidance system has become a major challenge in the research.

Today's air-to-air missile guidance systems rely heavily on radar beam or infrared homing technology, which is still in its infancy in this era, greatly compromising the accuracy and reliability of missiles.

Therefore, in many cases, the accuracy of anti-aircraft missiles in striking aircraft, bombers and warships is obviously insufficient.

At the same time, the technology of solid rocket engines and liquid rocket engines was not yet mature, which also limited the speed and range of missiles. For example, the range of the Sa-1 was only 30 to 40 kilometers, while that of the Sa-2 was 56 kilometers. The difference in firing altitude was even greater, with a difference of as much as 10 kilometers.

Of course, in addition to the above issues, there are also strict requirements in terms of materials and structure.

Materials need to be developed that can withstand high-speed flight and extreme temperatures while maintaining the lightness and strength of the structure.

Moreover, the electronic systems are mainly based on vacuum tubes, which are bulky, power-hungry and have poor reliability, posing serious challenges to the overall performance of the missile.

These problems need to be solved one by one, only in this way can it be called a relatively successful anti-aircraft missile. However, as far as the current domestic electronics industry is concerned, although vacuum tubes have been introduced, they are limited in production and cannot meet national demand at all. Only some top laboratories are using them.

Therefore, Zhou Tian’s team could only obtain some vacuum tubes through military channels, which undoubtedly delayed the research progress of air-to-air missiles.

Adding factors such as radar systems, it can be said that the time required to successfully develop an air-to-air missile is not just a few months, and may even take up to a year.

This is because Zhou Tian is like a cheat, otherwise it would take longer! Just like in the previous life, the research on Hongqi No. 1 lasted for nearly four years.

With the design drawings, the progress of researching Sa 1 naturally accelerated, and Zhou Tian also marked the data on the design drawings.

For two whole months, the four military missile experts never even stepped out of the laboratory. They ate when they were hungry, continued their research after they were full, and took a short break when they were too tired to open their eyes. After resting, they continued their research.

Day and night went by, and even Zhou Tian forgot how many days he had not been home.

It was not until the research on the Sa-1 anti-aircraft missile encountered a bottleneck that he suddenly realized that two months had passed.

Zhou Tian rubbed his greasy hair and looked at the radar in front of him, frowning and feeling distressed. Seeing that the Sa-1 missile was about to be successfully developed, he did not expect to encounter obstacles in the final radar system.

"Chief, what should we do next?" An expert grabbed his messy hair and asked anxiously.

The other three experts were also covered in grease. Their brand new uniforms when they first arrived were now stained with grease, and even their hands were black.

"There is no other way. We can only wait for the military's response! We hope there will be a guidance system that is suitable for our missiles!"

Zhou Tian said helplessly, a trace of sadness flashed across his face, and his bloodshot eyes looked like two red gems.

After all, the current domestic radar system is just starting out, and the detection range is only over 100 kilometers. Although it is sufficient under normal circumstances, the radar's response speed is really unsatisfactory. The guidance system itself requires an extremely high response speed, otherwise, it is just an expensive toy.

"Okay, you've all been exhausted from all this time, so take a good rest, take a shower, and change your clothes. Look at what you're wearing, you're almost wearing work clothes!"

After two months of getting along, Zhou Tian has figured out the personalities of the four people, and they have become much more familiar with each other, no longer as reserved as they were at the beginning.

"Commander, you are still talking about us, aren't you the same?"

After hearing what Zhou Tian said, the four people looked themselves up and down, and seeing that their whole bodies were black, they couldn't help but smile awkwardly. One of the experts looked at Zhou Tian and couldn't help but joked.

"It seems like this is really the case!"

Upon hearing this, Zhou Tian looked at himself and found that he was no different from the four others, so he couldn't help but laugh.

For a moment, in the entire underground laboratory, the five people's originally exhausted spirits gradually relaxed.

"Okay, let's go. The radar system is not up to standard, so even if we continue to research it here, it will be difficult to achieve results. Let's go back and have a good sleep. I'm so tired that I can hardly open my eyes!"

After laughing for a while, Zhou Tian stood up, stretched, yawned, and walked out first.

The four people looked at each other, felt that what the leader said made sense, and followed him out of the underground laboratory.

When they walked out of the test workshop, the five people were stimulated by the scorching sun and closed their eyes one after another. A sour feeling came over them and everyone's face became very ugly.

"Hello, director!"

The security soldiers at the door saw the five people walking out and almost didn't recognize Zhou Tian. After confirming again and again, they saluted in unison.

"Okay, let's go back first. We won't come to the experimental workshop these days. You continue to guard the door of the experimental workshop, and no one is allowed to enter. Do you understand?"

"Understood, Director!"

Several soldiers shouted loudly.

"Well, I'll be leaving first! By the way, Xiao Li, you guys should go back to the dormitory and rest!"

After giving a few more instructions, Zhou Tian left the test workshop, went to the office building, talked to his secretary Liu Yuan, and rode his bicycle home.
