Siheyuan starts from a good life

In the next few days, Jiang Yan met with Mr. Wu, who was in charge of large aircraft manufacturing. The two communicated very happily. Mr. Wu also benefited a lot from Jiang Yan's discussion with his eyes. Under the leadership of Mr. Wu, Jiang Yan visited several authoritative experts in my country's aerospace field. When they heard that we wanted to build a large aircraft, they didn't believe it at first, but when they were sure, they all expressed their unconditional support. In this way, the number of people in the large aircraft project snowballed. Every time they persuaded an old expert to join, they could bring a string of apprentices to follow!

Soon, Jiang Yan's research institute in Shanghai had almost all the researchers. Jiang Yan was quite generous to these people. As long as they did not have special requirements, they would basically be satisfied. He even gave them houses as long as they signed a 20-year contract. This was quite generous, and these conditions naturally attracted more people.

Soon after, the groundbreaking ceremony was held. There were many special requirements for the ceremony. The time, direction, feng shui, etc. of the foundation were very particular, and a special master had to be invited to calculate them. There were also very detailed requirements for the cornerstone itself. The groundbreaking ceremony for a large project even required the use of a golden shovel to pile up the soil.

However, it was only recently that the reform and opening up began, and some things were done tacitly, so some people did not say anything after seeing it.

On November 1985, 11, a grand groundbreaking ceremony was held at the Caojing River in XH District, Shanghai, for a commercial aircraft research institute covering a large area and jointly invested by Jiang Yan and the state.

The groundbreaking ceremony was quite grand. Jiang Yan had invited many people, including leaders from the Ministry of Civil Aircraft. Of course, there were also many invited reporters, including some from abroad.

First, the leader spoke on behalf of the group at the groundbreaking ceremony. He said that under the cordial care of the Party Central Committee, the State Council and the Development and Reform Commission, and with the strong support and help of relevant state ministries and commissions, the Commercial Aircraft Research Institute has officially entered the project establishment and construction stage. The construction of commercial aircraft is a major development trend of the country, and it plays a great role in expanding opening up to the outside world and promoting the sound and rapid development of Shanghai's economy and society.

Mr. Wu delivered a thank you speech on behalf of the group: "Thank you all for coming. The large aircraft project has officially started today! We must take the scientific outlook on development as our guide, design and develop large aircraft with high requirements, high quality, and international overall requirements. We can carry out extensive cooperation with international companies and strive to achieve a win-win effect.

The Commercial Aircraft Research Institute is planned to be built in two phases. The main contents of the first phase of the project include: administrative engineering office building, design building, as well as experimental production workshops, guardhouses and outdoor parking lots.

The main contents of the second phase of the project include: production workshop, aviation material warehouse, engine workshop and maintenance workshop.

The leader of the Development and Reform Commission also came forward to congratulate: "He hopes that the group will complete all preparations for the project as soon as possible, create conditions, and organize the construction as soon as possible. During the construction of the site, all participating units must follow the construction policy of high requirements and high quality, carefully design, manage and construct, ensure the quality of the project, strive to create high-quality projects, and strive to build a century-old enterprise.

Almost all the leaders who arrived took the stage to speak. The ceremony lasted for more than three hours and finally came to an end.

There were almost no experts from the group at the groundbreaking ceremony. What were they doing? Hundreds of experts were conducting the most detailed demonstration of the already produced Y-10 aircraft, discussing the areas that needed improvement and trying to come up with the best solution. The most difficult aspects of civil aircraft are safety and economy. If these two points cannot be achieved, the designed aircraft will hardly be marketable, which is not worth the loss.

After listening to the expert group's evaluation, Jiang Yan took a deep breath. I thought the Y-10 had already been produced, and I would spend some money to fly it, and then make some improvements, which would save a lot of time. But after listening to the experts, I took it for granted.

To be honest, the Y-10 aircraft is a copy of a certain foreign aircraft. It is now far behind the foreign aircraft, and it is not worth the cost to produce it. So after discussion at the meeting, they all agreed that the old Y-10 aircraft must be rectified, because the existing Y-10 aircraft have too many hidden dangers, and it was almost manufactured behind closed doors when it was first manufactured. Now that reform and opening up have taken place, why not take advantage of this favorable situation to introduce a large number of advanced technologies to transform the aircraft.

Therefore, they suggested that the redesign plan should be based on the Y-10, completely aligned with foreign aircraft designs, and that domestic resources should be integrated as soon as possible. In the manufacture of large civil aircraft, the four key evaluation criteria of safety, reliability, comfort and economy must be considered. Otherwise, it will not be able to adapt to market competition. "

In order to ensure that the large civil aircraft developed are internationally competitive and meet the airworthiness standards, we must first break through 10 key technologies: overall design technology of large civil aircraft, aerodynamic characteristics prediction methods of modern civil aircraft, noise prediction and noise reduction measures for large civil aircraft, load determination technology for large civil aircraft, efficient structure and strength design technology, etc.

In addition, the design of large civil aircraft also requires the comprehensive design technology of engines, aircraft onboard systems and aircraft. We estimate that under the current situation, the fastest speed of aircraft development will be around 1990 to produce a prototype and put it into operation in 1995. "

The meeting also decided to use global resources and Shanghai's advantages, and adhere to independent innovation as the basic principle that must be consistently followed in the development of large passenger aircraft. On this basis, deepen international and domestic cooperation to achieve mutual benefit and win-win results.

After listening to all the experts' introductions, Jiang Yan's anxiety was gone, so he stood up and began to express his opinion. "Everyone, I'll leave the big plane to you. I won't rush you here. Slow work makes fine work. I hope you can polish our own plane carefully. No matter what difficulties there are, we must continue to manufacture it. Don't be afraid of spending money! I will inject a lot of funds later and try my best to meet any needs. I believe you will definitely build the best and most advanced civil airliner in the world."

With sufficient money as a backing, I believe that with my countless investments, this big airplane can always be manufactured. As I said, I can afford the money. If it can be produced, it will be a huge profit. I believe that with the speed of national development and the demand for shipping, I am afraid that I cannot meet such demand.

The design work of the large aircraft officially began, and the first thing to be built was the wind tunnel.

Wind tunnel is the most widely used tool in aerodynamic research and testing. Its emergence and development are closely related to the development of aerospace science. Wind tunnel is widely used to study the basic laws of aerodynamics, to verify and develop relevant theories, and directly serve the development of various aircraft. Through wind tunnel experiments, the aerodynamic layout of the aircraft is determined and its aerodynamic performance is evaluated. The design of modern aircraft is highly dependent on wind tunnels.

The design of a new aircraft must go through wind tunnel testing. The airflow in the wind tunnel needs to have different flow rates, densities, and even temperatures to simulate the actual flight conditions of various aircraft.

Because of their good controllability and high repeatability, wind tunnels are now widely used in testing automotive aerodynamics and wind engineering, such as wind loads and vibrations on structures, building ventilation, air pollution, wind power generation, environmental wind fields, flow conditions in complex terrain, and the effectiveness of wind protection facilities.

However, building such a wind tunnel requires a lot of money. When the funds for applying for the wind tunnel were placed in front of Jiang Yan, Jiang Yan couldn't help but sob. This guy needed nearly 100 million yuan at once. This guy was not just talking about producing large aircraft. No wonder the rich second generations in later generations could do anything as long as they didn't start a business. This guy really spent money.

However, Jiang Yan was not stingy and invested the money with a wave of his hand.

Now the design department has more than 700 people, divided into more than a dozen groups. Mr. Wu is responsible for the liaison and coordination between the groups. He is also in charge of the key project group and has set up a new external liaison department to purchase and audit designs and parts that can be purchased internationally.

After a period of adjustment, each group has its own responsibilities. After Jiang Yan designated Mr. Wu as the final person in charge, he prepared to return to Sijiu City with Xu Damao. After all, he had been away for so long and missed home a little.

In the old city, it was December and Jiang Zihan had some free time. He had done a lot of things this year. After his car became a hit, he redesigned the air conditioners and refrigerators that we saw outside, focusing on exquisite appearance and energy-saving, hoping to be helpful to the country.

I heard from my father before that the domestic oil resources are not abundant and new energy sources need to be developed. The father and son also exchanged ideas about batteries. Jiang Yan naturally advocated lithium batteries, so she spent the rest of her time studying lithium batteries. Here he met two new companions.

One is a much older sister, or auntie, surnamed Zhao, who studies semiconductors and is now very interested in chip research. According to her, the research on chips is also thanks to Jiang Zihan's father Jiang Yan, who laid the foundation. Although domestic chips are relatively backward, it is better than nothing. In Jiang Zihan's opinion, he has a better understanding of his father.

To be honest, since he entered the institute, many things seemed to have been given to the institute by his father Jiang Yan, and many things, such as home appliances, were also sold, so she now very much hopes that her father will come back and have a frank talk with her.

Both of them are workaholics, and they occasionally communicated with each other and gradually became familiar with each other. They made some gadgets together, such as remote control airplanes, remote control toy cars, thermal imaging detectors, etc.

The second one is Miss Deng.

Ever since he tinkered with the off-road vehicle, Miss Deng appeared in his world after the celebration party.

Jiang Zihan is a workaholic. Sometimes he is so busy at work that he forgets to eat. Miss Deng always brings him meals, and slowly the two of them become familiar with each other.

But this girl is pretty good. I don’t know her name for such a long time, but Jiang Zihan feels very comfortable with her. It’s just that Aunt Zhao always smiles meaningfully every time she sees them, which makes Jiang Zihan feel a little puzzled.

Aunt Huang's home is also in Sijiu City, not far from Jiang Yan's home. When they have time, they often go home together.

On the way home that day, the two of them started chatting.

"Xiao Jiang, how old are you this year?"

"It's already 23, what's wrong, Aunt Huang?" Jiang Zihan asked.

"Your family has never urged you to get married." Aunt Huang asked curiously.

"Of course I have time. My mother urges me to go home every day, and I don't dare to go home even when I have time." Jiang Zihan said with a little annoyance.

"What do you think of Comrade Deng Zirui?" Aunt Huang continued.

"Auntie Huang! Who are you talking about?" Upon hearing this familiar name, Jiang Zihan slammed on the brakes.

"Aunt Huang, you were talking about Deng Zirui just now, right? She's there to tell me, okay?" Jiang Zihan pulled Aunt Huang's hand and spoke anxiously.

This really confused Aunt Huang. Only now did she realize that the unfortunate child didn't even know Miss Deng's full name.

"Xiao Jiang, come on, you don't even know the name of a girl you've known for two months? You're really foolish. Listen carefully, Xiao Deng's name is Deng Zirui, she's 23 years old this year, a few months older than you!"

"Her name is Deng Zirui!" Jiang Zihan kept thinking about this sentence on the way home! He was confused and didn't know what to think or what to say!

After sending Aunt Zhao home, he wanted to turn around and go back, stepping on the accelerator to the limit. He wanted to ask her if she had recognized him a long time ago? He also wanted to ask her how she had been doing these years? Was she okay?

But he didn't have the courage to do so now. After sighing, he drove back home with mixed feelings.
