Chapter 736 What Are We Going To Do?

The person in charge of civil aviation was the first to respond.

Shen Tu, who claimed to have no 'airworthiness certificate', directly sent several serial questions.

"I saw that some people raised questions about 708 again. Between words, it seemed that it was our mistake that 708 was dismounted. Here, I will elaborate on a few issues."

"1. Does the country have the giant hydraulic presses used for the keels of large aircraft made by the Americans and the Soviet Union, such as the 707?
2. Has the high-strength blasting welding technology passed the Chinese standard?

3. If there is a strong airflow when our Il-18 flies LS, can it ensure that the aircraft does not disintegrate?
4. I have been on the "708", which is a few meters shorter than the Boeing 707, but the empty weight is much heavier. At the same time, there are still many problems, such as the infrared lighting of the instruments, how can the night flight light dizziness ensure flight safety? !
5. There are strict management methods for civil aircraft in the world. How can the Yun-10 built in the "workshop" obtain the "airworthiness certificate" issued by the International Aviation Federation?
6. The Yun-10 is an obsolete model with high fuel consumption, which is not economically desirable, and it is impossible for the country to achieve self-sufficiency in large turbofan engines in a short period of time.

It is very expensive to buy an advanced aircraft, but it is even more expensive to buy spare parts such as engines for advanced aircraft. If you use imported 707 spare parts to assemble the Y-10, it will be a waste of time and money!
This little comrade is asked to do a good job of investigation before speaking, so as not to make people laugh. "

This is the person in charge of civil aviation who is called 'without airworthiness certificate'.

The ones mentioned do exist, and they are not fabricated out of thin air.

For a civil aviation aircraft, the most important thing is the airworthiness standard, and civil aviation is not a fool, so it has to take over the hot potato with the airworthiness certificate.

However, as the mother of Y10, the 640 Shangfei factory heard that the central government was planning to restart, and this mother actually destroyed the materials overnight, demolished the aircraft, and even held a labor competition to dismantle the aircraft production line to the point where it could not be put together again?

Probably because only the mother knows best what is going on with her child.

As for whether it is true, Su Chen has not participated in it.

Or in the eyes of some people, atomic bombs can be made by hand, nuclear submarines can be made by blacksmiths, and rockets can be made by hardware workshops.

But he is a person who respects the facts, if he can't do it, he can't do it, and it's useless to talk about other things.

You can't wait until someone is dead, and then bully him without opening his mouth.

At the same time, some people replied that Su Chen's manuscript was doing some inexplicable things, because the current technology is completely unmatched, and when choosing the direction of civil aviation airliners, we should not be greedy for foreign things, but should do what we can.

Someone else replied: "There is no hypocrisy or arrogance in science. Honesty and humility are fundamental. To build civil aviation airliners, we can't use the guiding ideology of "how bold people are and how productive the land is" to determine the direction of development."

Seeing the replies, he wrote again.

"The strategic significance of large aircraft is extraordinary. Although there are many reasons, I believe that only with the cooperation of multiple parties can we be truly independent, grasp the initiative, form our own unique industrial chain, develop our own technology system, and resist foreign countries. The pressure of the giants will strengthen our country's aviation market."

"But failure is the mother of success. Waking up from a nightmare is the morning. I hope that the developers of Yun-10 will sum up their experience and lessons, work hard, and build a new generation of Chinese passenger aircraft as soon as possible!"

He doesn't care how others reply at all, he just wants to raise this issue and attract everyone's attention.

But many people think that this guy is so annoying?

Always jumping up and down, talking about economics a few days ago, and now talking about big airplanes, what the hell are you doing?

With Su Chen's reply, the matter of the big plane came to an end.

After all, he didn't say that this project must be established now, let alone that this project cannot be abandoned.

Combining with Su Chen's previous article, it looks like a lot of thunder and little rain.

The importance of the big plane was mentioned before, but at the end it just gave everyone blood.

"What the hell is this guy going to do?" Someone couldn't help asking.

"I don't know, it seems like I came here to publish an article when I have nothing to do."

"I look like it too, otherwise I wouldn't have made such an inexplicable thing."

Although Su Chen did not continue to express his opinions on the issue of large aircraft, he did not stop doing things.

A new article will be written soon.

"On the 'Core Ball War' - the Pearl in the Crown of the Semiconductor Industry"

"We all know that semiconductor chip production is divided into three major links: IC design, IC manufacturing, and IC packaging and testing. As the core link of IC manufacturing, lithography is mainly used to transfer the chip circuit diagram on the mask plate to the silicon wafer.

Since the process level of lithography directly determines the process level and performance level of the chip, lithography has become the most complex and critical process step in IC manufacturing, and the core equipment of lithography - the lithography machine is known as the crown jewel of the semiconductor industry. Pearl. "

"In the long industrial chain of chip manufacturing, the lithography machine is the most dazzling pearl. If the aero-engine represents the top level of development in the field of human technology, then the lithography machine is the most dazzling pearl in the semiconductor industry."

"Today we are talking about lithography machines alone. In 1952, the smoke of World War II had just dissipated. China started the computer industry. The country established an electronic computer research group, which was headed by Hua Luogeng, the director of the Institute of Mathematics...

In 1956, my country's first crystal triode was born, in 1958 in my country...1961 in my country...1962...1965, my country's first integrated circuit came out in BJ, SJZ and Shanghai one after another. "

Let’s take a large amount of data as an example.

Referring to the projects that the lithography machine has achieved in recent years, "In 985, the 45th Institute of the Ministry of Mechanical and Electrical Engineering developed a prototype of the step-by-step lithography machine, which passed the technical appraisal of the Ministry of Electronics and was considered to have reached the level of the 4800DSW in the United States.

This should be China's first step-by-step projection lithography machine, which uses a 436-nanometer G-line light source.According to my understanding, the gap between China and foreign countries in step-by-step lithography machines is no more than 7 years. "

"Small TVs and computers, as large as aircraft missiles, are all inseparable from chips, and chips are inseparable from lithography machines. If we stop semiconductor research, maybe one day our missiles will use chips designed by others and fly out. Sometimes it hits itself instead."

"Or, we have been pursuing the 'bringing doctrine', what should we do if others don't give it to us?"

"If someone sells us a chip that can open the back door and remotely control our aircraft missiles, what should we do?"

"Or someone will not sell us semiconductor-related equipment one day, and we are lagging behind others, what should we do?"

"If one day there is another ordinance similar to the 'Batumi Agreement', prohibiting the list of dual-use goods and technologies.

Covering 9 categories including advanced materials, material processing, electronic devices, computers, telecommunications and information security, sensing and lasers, navigation and avionics, ships and maritime equipment, propulsion systems, and various weapons and ammunition, equipment and combat platforms There are 22 categories in total. "

"If our semiconductor industry is only stuck in the manufacturing stage because of the lack of core technology, how many years will we be behind other countries?"

"In the movie, the protagonist makes deals with the devil at every turn, but there are no devils in the real world, only the frequent renunciation between countries! We must always be vigilant against those who will never die."

When this manuscript was written, Su Chen handed it to Xue Fang: "Help me get it published in "Beijing Daily."

Xue Fang took a few glances and frowned: "Have you changed your career to be a magic stick recently?"
