Chapter 522: Only Attack-5 Blueprints Are Not Enough
Gao Zhendong spent New Year's Eve at Lou's house. On the first day of the new year, he took Lou Xiao'e to the temple fair with great interest.

For Gao Zhendong, every visit to this place is always full of novelty, mainly because the temple fair is very down-to-earth and not at all pretentious, and the main feature is the liveliness.

If you want to see fun things, there are those; if you want to eat delicious food, there are those too; if you want to buy rare things, there are those too. Although there aren’t many rare things these days, what you want is the atmosphere.

Moreover, for Gao Zhendong, in fact, he finds many things these days quite rare. This is mainly because of his preconceived life experiences in his previous life. In this life, when he looks at things from the 50s and 60s, everything he sees is new.

He even looked at the big candied haws sold at the temple fair with great interest for a long time, and even bought one to hold in his hand. It was so damn long that to eat it, one person had to hold it, and the other person had to be far away to eat it. If there was only one person, they would have to bend it and eat it, otherwise they wouldn't be able to reach the top.

One of the couple hung the candied haws in front, while the other stood behind and reached up to eat them. They would take turns after eating two.

Lou Xiao'e was holding a windmill in her hand and was happier than a child.

The two of them bought a lot of things, useful and useless, just for fun. At worst, they could give them to the children when they returned to the courtyard.

When they got home, Lou's mother looked at the pile of gadgets and laughed at Lou Xiao'e: "How old are you? Why are you still buying these things?"

Lou Xiao'e was laughing and giggling, picking out a few small purses from a pile of things like offering treasures: "Come here, Mom, these are for you. Dad didn't even know to give you something for the New Year, so it should be me, right?"

Although Lou's mother expressed her disgust, her actions betrayed her. She took the thing from Lou Xiao'e and said, "Well, it's quite nice."

Father Lou, who was stabbed on the back by his leaky cotton jacket, walked down from upstairs, coughing as he walked. He didn't have any illness, but he just wanted to cough a few times.

It was Chinese New Year at that time and there were only three days of holiday. Gao Zhendong and Lou Xiaoe wandered around for two days and spent the remaining day celebrating New Year's greetings.

But now that I know more people, it doesn't seem appropriate to go here and not go there. I might as well treat everyone equally and not go anywhere, except to my own master's house and a few comrades' houses. Don't even think about it, because I'm too busy with work.

After three days, Gao Zhendong went about his business. On his way to work, he saw groups of children setting off firecrackers on the roadside.

As soon as he arrived at the office, a comrade from the confidential room of the Third Branch Factory called him and said that there were several documents that he needed to pick up in person. It was not that the comrade from the confidential room was unwilling to deliver them, but according to regulations, they could not deliver them and he had to pick them up himself.

Gao Zhendong went over to sign for the items, then returned to his office and unpacked them one by one.

The first one was the masks he commissioned Northeast Optics to make. The three branches of the factory could not make these masks. They included a set of standard test masks and a complete set of photolithography masks for the three chips: SZ61000, SZ61001, and SZ61002.

These names are completely imitated from CD4000 and 74/54. Needless to say, the "number" was born in 61, and this series has had to carry 61 since then. As for the three-digit codes at the end, it was a lesson learned from the 74 series. At the beginning, we didn't expect so many, so we kept two-digit codes. In the end, we found that it was not enough, so we had to increase it from 74XX to 74XXX.

Looking at this thing, Gao Zhendong made a phone call to the lithography machine assembly workshop. Now this was all that was missing.

"Boss Gao, um, it's almost done. I estimate it will be ready in a few days."

Gao Zhendong said: "Don't rush to hand in the work. The necessary preliminary tests, experiments and trial runs must be done well. Sharpening the knife does not delay the chopping of wood."

The person on the other end of the phone repeatedly assured us that the product would never be transferred to production with problems and would only be put into production after it had been fully tested.

After hanging up the phone, Gao Zhendong picked up the second thing, which was a thick file bag.

The document came from the National Defense Committee. After opening it, I found that it was not a printed copy. There were many diagrams in it, which were a bit beyond the scope of today's computers and supporting software. On the contrary, a dot-matrix printer could barely keep up with the needs.

When I have some free time, I will definitely get some drawing software! Gao Zhendong vowed to himself.

It is unknown where the document came from, but from the content, Gao Zhendong could tell at a glance that this thing must have come from the Porcelain Capital.

This is the aircraft that the leader of the Defense Work Committee mentioned to him during the last meeting, the Gong-5 attack aircraft, but the leader did not go into too much detail at the time and did not even mention the model.

But this time, the materials were very complete. Not only was the model clearly identified, but Gao Zhendong was basically given everything about the Attack-5 attack aircraft, even the structural diagram was attached in its entirety.

Except for the parts drawings which were too trivial, it can be said that everything about Gong-5 was completely presented to Gao Zhendong. After getting this set of materials, Gao Zhendong spent two days to read everything about Gong-5 in full and carefully. Many originally vague ideas gradually became clear in his mind, and many ideas that had not been there before emerged in his mind.

The more he thought about it, the more excited he became. It was not just about the Gong-5 and the future semi-active air-to-air radar missile itself. He was even bold enough to think about the entire system.

No matter what, he wanted to give it a try!
Back to the Gong-5 itself, its main design had actually been completed at that time. As for why Gao Zhendong's first flight was not scheduled until 65 in his previous life, that is another story.

Judging from the design of the Gong-5 and the environment it is in, it is excellent. Although it has short legs, a small payload, and flies slower than the Type 6, it has achieved almost all of its preset goals under limited conditions and with limited inherent deficiencies.

Except for one thing that seems to be a major flaw: the legendary one-way ticket to sell mushrooms, this is not because the design requirements were not met, but because the requirements are like this. We are in that condition, and we have no choice but to use sacrifice to defend everything we have.

He began to write an email, most of which was written more to his comrades in the Porcelain Capital than to the Defense Work Committee.

In the office of the leader of the National Defense Work Committee, the leader of the National Defense Work Committee was looking at Gao Zhendong's email in his hand. Up to this time, the offices of high-level leaders were still not equipped with computers. Every computer produced was sent to the places where they were most needed.

In Gao Zhendong's letter, there were not many references to semi-active radar air-to-air missiles. In fact, it was only mentioned at the beginning that the nose space of the Gong-5 attack aircraft could meet the expected fighter radar requirements after slight improvements. The rest of the letter was full of suggestions and opinions related to the Gong-5.

This was exactly the effect that the leaders of the Defense Work Committee wanted to achieve, and Gao Zhendong did not disappoint them. He looked down with joy.

But the more he looked back, the more solemn his expression became. It was not directed at the design team of Attack-5. Apart from some details, they had done a good enough job.

More doubts actually come from the technical and tactical requirements at the beginning.

When the leader saw Gao Zhendong’s last request to the end, he felt that Gao Zhendong was going to do something big.

On the last line, Gao Zhendong made a request: "I hope to get the information about the Il-28 light bomber that we are using and preparing to copy."

As for the later Z-5 light bomber, Gao Zhendong was well aware of its basic data. The reason why he specifically asked the Defense Working Committee for it was that if he didn't want it, he couldn't explain how he knew the data of the Z-5.

The second reason was that he wanted to further understand the details of the aircraft before evaluating whether his idea could be realized, rather than making a judgment based on just the basic data in his mind, which was not scientific enough.

What he wanted to do next was a big thing and very difficult, and any improvement in the details would help increase the chances of success.

He did not intend to use the Z-5 to undertake special tasks or carry out specialized modifications. This is a light bomber, and its modification potential, ceiling, speed, and load capacity are not very good, which makes it difficult to handle. What he had in mind was a regular, long-term, formal tactical mission.

After reading Gao Zhendong's request, the leader of the Defense Work Committee fell into deep thought. What was Gao Zhendong going to do? It was not that he did not believe Gao Zhendong, but he felt that Gao Zhendong seemed to be doing something big.

After thinking for a long time, he still couldn't figure it out, but he still chose to believe Gao Zhendong. This young man had never disappointed anyone. In short, his starting point for making this request was definitely good.

He called his correspondent over and handed him the marked mail.

"Forward this part to Cidu." The leader pointed to the part with some suggestions about the Attack-5 type.

After that, he pointed to the last part of the letter and said, "In addition, the sooner Comrade Gao Zhendong's request is met, the better."

A certain unit in the Porcelain Capital received an email forwarded by the National Defense Work Committee. To be precise, it was half an email, because you can see at a glance that the beginning and the end of the email have been cut off, and it is no longer possible to tell who wrote the letter.

The content of this half email is some suggestions on attacking Type-5.

"The two cannons on both sides of the nose have the potential for smoke to be sucked into the engine when firing, causing the engine to malfunction or stop. It is recommended to rearrange them."

From this design, we can see that our designers at that time were seriously inexperienced, and they didn’t even have a way to digest and absorb the existing lessons learned. This is also the common sense from previous lives that Gao Zhendong casually mentioned. The reason why some people are amazed by it these days is that we really lack knowledge and experience.

The placement of the aircraft cannon in front of the engine air intake may cause the engine to malfunction. In fact, this problem has existed for a long time and appears more frequently on Russian aircraft. The most typical and exaggerated one is the Russian MiG-9, which places the largest aircraft cannon almost in the center of the engine air intake.
