C919, in Tan Zhenhua's past life, was not only the pride of Chinese people, but also a difficult and tortuous history.

As mentioned in the previous article, China’s large aircraft journey was extremely difficult and bumpy. Starting from the "Yun Ten", it has almost gone through all the pits in the world. It was not until 2008 that I finally made up my mind and launched the plan to develop a modern single-aisle mid- and short-range trunk airliner based on the integration of the world's top component suppliers' supply chains, which later became the C919.

The starting point of this aircraft is very high. It is China’s first trunk-line civil aircraft with independent intellectual property rights in full compliance with the latest international airworthiness standards. The meaning of its name is: the first letter "C" is the first letter of China’s English name "China" , Is also the first letter of the English abbreviation COMAC of China Commercial Aircraft Corporation. The first "9" means forever. "19" represents the maximum passenger capacity of this type of passenger aircraft of 190.

According to its original design, under the standard two-cabin layout and economy class 3+3 layout, this aircraft has 156 seats, a range of 4,000 to 5,000 kilometers, and a maximum take-off weight of 72 tons. Competitors targeted by this type of aircraft are Boeing 737 and Airbus A320.

A few months before Tan Zhenhua’s rebirth, on May 5, 2017, the C919 had already made a successful first flight and won an expected order of more than 1,000 aircraft. However, although Tan Zhenhua did not know what happened afterwards, at least there was One thing he can be sure of is that for this new passenger plane of China, it will be extremely difficult to obtain the EU Aviation Administration EASA and the US Federal Aviation Administration FAA license.

This is related to the performance and quality of the aircraft. However, with the manufacturing level of China at that time in 2017, the design and manufacture of this aircraft should definitely be at the top level in the world. The difficulty of this, and more importantly, actually comes from the FAA. And EASA's deliberately making things difficult and obstructing-as for the reasons, no explanation is needed.

Today, Tan Zhenhua decided to start this plan 22 years ahead of schedule. This is not only because Secretary Lu entrusted him with solving the major problem of the future of the more than 7,000 employees of the Modu Aircraft Manufacturing Plant, but also because he knew that there were some opportunities. Fleeting.

After sending off Sir Hook, Tan Zhenhua sat alone in the office for a long time, and finally called Sister Monica, who had been transferred to his chief confidential secretary, and asked him to send a telegram to China.

"Master Ma, your telegram."

Wu Guanghui rushed into the office happily, and handed the telegram in his hand to Ma Fengshan, who was having a heated discussion with a group of designers in the large office, and said, "I just passed the communication room and just saw it. I brought you here."

After graduating from Ning Hang, he was assigned to 3603. Wu Guanghui, who took the initiative to join the "BAC" project, was no longer the young man who helped Guo Rongwei to organize the information when he first met Tan Zhenhua. He is already 26 this year. Years old, experienced the entire process of the “London Party” introduced by the “BAC” passenger aircraft, and participated in the entire work flow of the vigorous production line from the disassembly of the British to the installation and commissioning of the Xi’an Aircraft Factory, and the “BAC” test afterwards. It has been tempered in a series of major projects such as production and localization of parts and components, and it has become a leader and leader among the younger generation.

Ma Fengshan likes this young man very much, and has made up his mind secretly-at the end of this year, he himself will be qualified to be promoted to researcher-level senior engineer (equivalent to full professor level in colleges and universities), which means that he will be able to take PhD students Ning Hang will also specially hire him as a visiting professor after he is promoted. At that time, he intends to accept Wu Guanghui as his pioneering disciple. He will directly come to master and PhD students to study without delaying work. Isn't it good to train him as his successor?

He smiled and accepted the telegram handed over by Wu Guanghui. He tore open the envelope easily, but after reading the line of the telegram, he instantly petrified.

The sudden change of Ma Fengshan's expression quickly attracted the attention of everyone in the office. They all stopped their movements and watched this scene in amazement, and Wu Guanghui, who was the nearest to him, discovered that the corner of the chief teacher’s eyes, There were glittering tears flashing.

This is a large office specially designated by XAC. In fact, it is more appropriate to say that it is not so much an office as an auditorium-because there are more than 300 people working in this office, and these are more than 300 The vast majority of the people come from the original "Yunshi" R&D team. The reason for this arrangement is entirely at the request of Ma Fengshan. He believes that the design of each part of the aircraft affects the whole body, so that the office layout that breaks the boundaries of the departments is most conducive to the communication between the departments, and it is also conducive to the coordination of the design contradictions between the various sub-systems-for large aircrafts. For large-scale system engineering, it is not always possible to get the best results by stacking all the best parts together. Balance and compromise between each other to achieve performance, cost, compatibility, safety, manufacturing difficulty, etc. Acceptable results in all aspects are the ultimate goal.

In fact, there is another point that Ma Fengshan did not say clearly. The more than three hundred people in this office are the ones that have finally survived. The most elite core personnel in the original "Yunshi" design team are the hopes for the future of China Aircraft. , He didn't want to keep it away from his sight for a moment.

At this time, more than 300 eyes were cast on Ma Fengshan.

Wu Guanghui whispered, "Chief Master, Master Ma, what's wrong with you? Zhenhua should be the one from the United States? What did he say?"

Wu Xinshi and Cheng Bushi, two old partners of Ma Fengshan, the former deputy chief designer of the "Yun Ten", and the current deputy leader of the "BAC" project team immediately gathered around when they saw this, and asked with concern: "Old horse, how do you return? What? Is it uncomfortable?"

"No, I'm fine." Ma Fengshan finally reluctantly controlled his emotions. He who had never been smirking suddenly showed a big, brilliant smile at Wu Xinshi and the others, and he waved the seal in his hand. Telegraph: "And it's the best moment I feel in these years."

Cheng Bushi asked straightforwardly: "Old Ma, what the **** is going on? Oh, you look like this, you are so anxious."

"Let's take a look. This is the telegram that Zhenhua just sent." Ma Fengshan handed the telegram in his hand to Cheng Bushi and said, "You can understand it at a glance."

Cheng Bushi received the telegram, only glanced at it, and shivered all over, and then handed the telegram to Wu Xinshi. After Wu Xinshi finished reading it, he was demented for a long time, and then suddenly burst into tears.

Wu Guanghui couldn’t understand why these gray-haired elders became so gloomy after seeing a telegram from Tan Zhenhua, they couldn’t help being curious, and took the telegram to see-the telegram Very short, only 5 characters:

"I'm ready".

"I'm ready, I'm ready, I'm ready!" Wu Guanghui chanted these short 5 words, his voice getting louder and louder, and he couldn't help himself. He waved the telegram over his head with both hands, from his chest. Zhong yelled out:

"Tan Zhenhua said he is ready!"

This sentence is like a signal. After a brief silence in the office of Norwegian University, it immediately fell into a state of collective excitement and madness. An emotion that had been suppressed for too long suddenly burst: some people During the stomping, some people were applauding, some were crying, and some were laughing wildly, but everyone shouted from their chests: "He's ready!"

"He's ready, what about us?" Ma Fengshan shouted the question hoarsely.

"We are always preparing!"

More than 300 people answered in unison and went straight into the sky!
