Chapter 29: Cooperation Cancelled; Lucy, This Is Not Okay! (Please Read)

Cancel the cooperation with CFM on the overall integrated propulsion system? Daxia wants to develop its own 100% domestically produced propulsion system?
"The memorandum of cooperation for this project was signed last year, and it is expected that the cooperation will be formally carried out in two months."

Xu Qianren frowned and expressed his concerns: "If we change it now, it may not be that easy."

When COMAC was established last year, it had already set the tone of using the engine propulsion system provided by CFM.

Now that everything is ready, making such a huge change now would be like wasting more than a year of hard work.

He found this somewhat unacceptable.

Zhang Yuli stared at him and repeated what he had just said: "This time we developed everything ourselves, including their engine integration system."

"Build a 100% domestically produced large aircraft!"

Xu Qianren was confused: "President Zhang, if we cancel the cooperation with CFM, with the current self-development capabilities of Daxia Commercial Aircraft."

"It takes too long to build a suitable engine propulsion system, and the C919 project can't wait that long."

If a purely domestically produced propulsion system can be used, who would be willing to use someone else's engine?

He was unwilling, and Daxia Commercial Aircraft Company was even more unwilling.

Xu Qianren saw the true colors of these foreign companies very clearly, no matter how nice they sounded during the initial negotiations.

Today, CFM will try its best to meet COMAC's requirements, and even provide a preliminary plan for the overall integrated propulsion system in the fastest time possible.

But this is only because the cooperation has not officially started yet. When they need to mass-produce aircraft, companies like CFM will definitely use their traditional skills to raise prices when necessary, limit sales when necessary, and will never let you down when it's time to strangle you.

However, how easy is it to develop an economical and practical aircraft engine? Time waits for no one!

"Choosing CFM as a partner is really a stopgap measure." Xu Qianren sighed: "In the future, we will definitely switch to a domestically produced integrated propulsion system."

"In order to develop a domestically produced large aircraft as soon as possible, we have no other alternatives."

After all, as a joint venture between Aero Gallic and General Electric, CFM accounts for more than 40% of the global commercial aviation engine market share, including General Electric's original 15% share.

CFM International as a whole owns more than 55% of the market share, making it almost a giant in this field.

As you can tell from its name alone, the full name of CFM is: International Engine Corporation. If we don’t choose it for cooperation, there will be no better alternative.

Zhang Yuli and others were also very clear about this: "I know your concerns. How could you rashly cancel the cooperation without full preparation?"

Facing Xu Qianren's puzzled gaze, he took out a large stack of freshly printed drawings and said, "Take a look at these first, and you'll understand why I say that."

Picking up the top few drawings, Xu Qianren was stunned when he saw them.

【Analysis of the new flight management computer system (FMC).】

[Analysis of new commercial aviation high thrust engine:
Using the total thrust of 83% bypass airflow and 17% core airflow will minimize fuel combustion in the combustion chamber of the turbofan engine. Using Iec to dynamically control the N1 axis speed, the thrust of all core and bypass airflows can be adapted to the current flight state.

【Technical Parameters:
Fan diameter: 3.251m.

Number of high-pressure compressor stages: 9.

Low-pressure turbine: 6 stages.

Maximum thrust: 520KN】

"Hiss what is this??"

Xu Qianren took a quick look and immediately gasped: "What is this? The design of a super-large civil airliner?"

Although he held a management position rather than a scientific research position in COMAC, how could he not be aware of the value of these technologies?
Just from the perspective of the 520KN thrust engine, isn't it very close to General Motors' GE-115B?

"Now you know why we have to cancel our cooperation with CFM, right?" Zheng Lixing said cheerfully as he drank tea nearby. "I know. I'll go back and inform the people at CFM right away!"

Xu Qianren nodded, his hands trembling slightly with excitement.

He fully believed that this technology was absolutely real.

There was no reason for Zhang Yuli and Zheng Lixing to lie to him about such a thing, and the notice for him to come to Xia Ke Institute was issued directly from the highest-level meeting.

With this kind of technology, who would be willing to serve these foreigners?

Get down here, everyone!
the next day.

Nine in the morning.

Today is Saturday, Lu Ze’s favorite day off.

Eagle sauce, in the small town outside the LLNL laboratory.

It was still the same coffee shop. Lu Ze sat quietly on a chair on the street and ordered a cup of coffee.

He was holding a book in his hand, reading it with great interest: "Wow, there is actually a move that can drop from the sky?"

Of course, the title of the book excludes Jin Ping Mei first.

"Sir, your iced latte." This was a female voice that seemed familiar.

"Okay, just put it on the table."

Lu Ze was still absorbed in reading and replied without even looking up.

He took a sip of the iced latte, and suddenly a huge bitter taste filled his mouth: "Pfft, why is it still so bitter?"

"Is there something wrong with this coffee shop? Didn't I tell you to put sugar and milk in your coffee?"

Just as Lu Ze was complaining, he heard a pleasant laugh: "Lu Ze, coffee should not be added with sugar or milk by default. Only in this way can you taste its original flavor."

"So, do you know why I never eat bitter melon?"

Lu Ze looked at the girl in front of him with helplessness.

He had said many times that he didn't drink coffee without sugar, but she just wouldn't listen and kept asking him to try it.

Lucy, wearing a white shirt and jeans that revealed her perfect figure, had her back to the sun and even her hair was shiny under the light. She looked like the perfect combination of cuteness and beauty.

The return rate is one thousand percent.

Lu Ze has become somewhat immune to this kind of beauty.

He frowned and drank the unsweetened ice latte with difficulty: "Lucy, what do you want to talk to me about today?"

If Lucy hadn't called him out early in the morning, he would probably have stayed in the dormitory and slept in.

"Lu Ze, is it fun in Da Xia?" Lucy sat down and supported her chin with her hands.

To the West during this period, everything in Daxia was shrouded in mystery.

Lucy even asked him several times before: Do people in Sichuan ride pandas to school every day? Can he give her one?

Are you kidding? He himself has barely seen a panda many times!
"I think it's pretty good, at least much better than here in Eagle sauce." Lu Ze thought for a moment and continued: "There are many cultural relics in my hometown, such as the thousand-year-old murals of Mogao Grottoes, the spring breeze does not pass Yumen Pass, etc."

After all, compared to the United States, which has a history of only more than 200 years, every place in Daxia is a famous scenic spot and historical site.
