Autumn is a beautiful season. No matter where autumn is, it is very beautiful.

In the south of the Yangtze River, there are certainly autumn, but the plants and trees wither slowly, the sky is always light, and it is often rainy and less windy; in my hometown, Hangzhou, I can only feel a little coolness. The taste of autumn, the color of autumn, and the artistic conception of autumn are always a little bit worse, making it impossible for people to appreciate the true style of autumn. Autumn is not a precious flower or a high-end wine. It is not appropriate to appreciate autumn and autumn with a flower appreciation and drunken attitude.

In Beijing, the reed flowers beside Taoran Pavilion, the weeping willows in Diaoyutai, the moonlit night in Yuquan, and the bells of Tanzhe Temple. Even if you don’t go out in Beijing, you will wake up in the morning and make a cup of fragrant tea and sit in Siheyuan. When you look up, you can see the blue sky, sit under the locust tree, and look at the rays of sunshine that penetrates through the leaves. Or in the small vegetable field in the backyard, you can see the trumpet-like morning glory. I think you can feel the pleasant autumn feeling.

The old locust trees in Beijing are also a kind of autumn embellishment. They look like flowers but not the falling stamens of flowers, and they are spread all over the ground. When you step on them, you can only feel a little softness. After the girls who swept the streets, the silk patterns of brooms left on the land look leisurely and delicate. Now when you think about it, you still feel a little lonely. The sycamore tree leaves and the world knows autumn, maybe it is in these deep places.

There are also the singing of autumn cicadas. Beijing was originally full of trees, and the houses were low, and it could be heard no matter where it was. If it was in the south, it could only be heard in the suburbs or on the mountains. In autumn in Beijing, the rain seemed to be more interesting than the autumn rain in the south, and it looked more like rain. In the gray sky, a cool breeze came, and then it drizzled. After a shower, the clouds gradually drifted westward, the sky became blue again, and the sun's face appeared again. I remember that at that time, the old guys bit the tobacco pot, went up to the bridgehead to gather under the trees, chat, and let the birds go. The days were leisurely.

When autumn comes, fruit trees in Beijing are also a symbol of the arrival of autumn. Take the jujube tree as an example. Look at the corners of the house, the walls, the edges of the thatched cottages, and the doors of the kitchen. When the dates, like pigeon eggs appear to be a faint green and slightly yellow color among the small and oval leaves, it is the heyday of autumn. When the dates, persimmons, and grapes mature to eight or nine minutes, it is also the most beautiful time in autumn in Beijing, and the best time of the year.

These beautiful scenery and things were loved by the elderly before today. Although the elderly have been very busy, they always like to get close to nature and enjoy nature as they are older.

But today everything was different. In the morning, I turned down the walk plan with a few old friends yesterday, and then said "no" to two seminars. After that, the old leader called to inquire and just had to deal with it. All this was because of the big envelope in front of the old man, the letter in it, or a paper. At first, the old man disagreed with the letter he received, thinking that it was another young man who didn't do serious business and wanted to become famous overnight, and said: "Young people today are very impetuous, no longer as before, thinking about the past..."

But by some devils, the old man opened the letter and read it.

The old man was completely attracted by the small part of the front just after seeing it.

This paper describes exactly what the old man is most concerned about now. The old man relies on his own strength to advance the successful development of China's rockets and atomic bombs by at least ten years. Although in the eyes of the old man, these "remarkable achievements" are by no means something that a single person can achieve, and what he does is only one thousandth or one thousandth. In the letters between the old man and others, he also repeatedly emphasized that the research, design, manufacturing and experiments of atomic bombs, hydrogen bombs, missiles, satellites are the result of the joint cooperation of thousands of scientific and technological experts, and it is not the independent creation of any scientist. He is just a "drop in the ocean", but to be honest, the old man is still very proud of his decades of hard work.

Over the years, especially in the past decade, the elderly have been resentful about something. Tell me, we have turned into missiles, atomic bombs, and hydrogen bombs, but why can't we make a big plane? Is that really that difficult?

The old man was quite confused about this, but the large aircraft project has always been trapped in the difficulties of composite materials and cannot move forward. In the past few years, he even gave up independent research and development and engaged in joint development with the Americans. Isn’t this a big shrimp to pull eggs - nonsense? What is the American? Will he be kind to him?

The old man actually has a deep understanding of Americans. After all, he spent a lot of time in the United States, and even went through a lot of trouble in returning to China. It was only after the Premier's repeated efforts that he finally returned to China smoothly.

From then on, the old man was deeply wary of Americans. Besides, what was related to national defense plans, how could he deal with other countries? Although Americans seemed to be extremely friendly to China in the past two years, people who were slightly sober could see the tricks clearly. However, the old man still could not make much impact on the decisions of the country, and he had no intention of interfering in the decisions of the country. The old man thought he was a pure scientific researcher and a very traditional Chinese, so although the old man had many complaints about the matter of large aircraft, he had never made any fierce remarks about it.

However, over the past period of time, he heard that the country and the US McDonald had a lot of differences on the issue of cooperation, and there was even the possibility of cooperation breaking down. The old man was extremely anxious about this, but he could do nothing about it. If he was limited by mechanics and other aspects of his expertise, he would definitely have nothing to say. He tried his best to solve it, but this was limited by the materials. Although he had been paying attention to it over the years and had read a lot of related books and materials, he was still in a difficult position! It was really like a mountain in his heart. The old man lamented in his heart.

However, years of investigation still made the old man look very different. This is an alternative, long-term illness and has become a good doctor. The old man smiled helplessly.

The old man saw the paper in front of him and found the mystery. The old man couldn't help but secretly glad that if he hadn't been in the past few years, he would have stuffed this thing into the garbage can at the door as soon as he saw it?!

This long paper mainly describes a composite material named GS(*-*)MG and an additive named GSRB. The old man had no idea how these two strange names were named, and he couldn't tell what they were named after. Holding the name was just a code name, the key was the idea of ​​the content. The old man did not entangle in such details and continued to read.

Out of the vision of many years of research, the old man was very shocked by these two materials. Perhaps there is nothing special about the separation of these two materials, but when the two are combined, a strange reflection will occur, thus having extraordinary performance. This performance is really a perfect match when used on aircraft.

The old man had to be fascinated by the author of this article. This shouldn't be something that people can think of. It's really incredible.

What makes the elderly pay more attention to is that several aircraft design models are added to the paper, and preliminary analysis of some related aspects such as the initial overall design parameters and scheme design of the aircraft, the design and analysis of aircraft operation system, the analysis of aircraft cost and efficiency, and the optimization of aircraft overall parameter are given.

Although it is not an expert in aircraft design, the old man intuitively judged that this is extremely feasible, and when the product is designed, it will definitely lead the world for more than ten years. This is an amazing conclusion, because it means that China has lagged behind the world for at least 30 years in aircraft design and manufacturing to surpassing the world's advanced level for at least ten years. This span is really amazing, and China's national defense will be qualitatively improved.

After reading the paper, it was almost midnight, and fourteen hours had passed without realizing it. The old man shook his head a little dizzy. It seemed that many years have not been reading such a long time, right?

Although so long has passed, the old man is not sleepy at all, which is also an incredible thing for an elderly man who is about to turn 76 years old.

I couldn't help but feel excited and ecstatic in my heart. The old man kept walking around in the study. Soon, the old man seemed to have made a major decision and resolutely picked up the phone in the study.

"Is it the old leader? What? The old leader is resting? Who am I? I am Qian Xuesen! Please call the old leader, but I have something urgent to ask him for. How urgent? Hundreds of thousands of times! In addition, please ask him to find all the experts in aircraft design. Yes, all! I have important things to discuss with these experts." After making the phone call like firecrackers, the old man shook his head. How many years have he been not so impulsive? It seems that it has been almost twenty years, right? "Time flies so fast!" The old man looked at the final signature of the paper and said to himself.

The final signature of the paper clearly shows: Zeng Lingfeng.

Yes, you read that right, it is the three words "Zeng Lingfeng". This paper took Zeng Lingfeng six months to sort out. The content here is absolutely credible, but the content inside is not his research results, but the research results obtained by a special research group established by China in 2012 in 2020.

The old man’s judgment that this achievement is ahead of the world is correct, but it is still too conservative. You should know that even in 2020, this achievement has reached a leading level. Therefore, if this achievement is applied now, it will be at least thirty years ahead of the world.
