Chapter 32 Want to increase the price? No, our cooperation is over!
"Super thrust aircraft engine? Are you kidding?"
With strong doubts, Qin Huaichang decisively pulled out the top one.
[Analysis of new super-thrust aero-engine drive system device]
[EEC will adjust the HMU according to the current thrust proportional command so that the current fuel efficiency is reduced to]
[The gearbox drive output power supply operates at a frequency of 415hz. In order to reduce the possibility of damage by N2 speed, it will be driven by a constant speed drive device and an AC motor to ensure a fixed speed.]
The most eye-catching thing here is not the detailed explanation of the engine technical design.
The number marked eye-catchingly at the bottom is that the maximum thrust is 520KN
"His 520KN thrust? Design specifications are that high?"
Qin Huaichang took a breath of air and his teeth were sore: "No wonder they want to build super large civil aviation aircraft"
520KN is equivalent to an incredible number of 53 tons of thrust. Even if it is not a super-large civil aviation aircraft, it cannot use this high-thrust engine.
Even if the aerodynamic layout of the aircraft itself is a little worse, there is absolutely no mistake in describing it as if this engine is flying bricks with all its force.
"Lao Xu, where are the other technical outlines and the entire technical implementation process below? Where did you hide them?" Qin Huaichang turned over several pages but couldn't find it, and asked eagerly.
"The remaining information is still with Xia Ke Academy." Xu Qianren smiled happily.
He was slowly trying to pour himself a cup of tea, but Qin Huaichang, who had quick eyes and quick hands, filled it directly.
"When will Xia Ke Academy send over the remaining technology?" Qin Huaichang's wrinkled face seemed to have squeezed out a flower at this moment.
"After the C919 project is restarted, the follow-up information will be sent to COMAC." Xu Qianren drank the tea poured by Qin Huaichang, feeling happy in his heart.
As an old friend for many years, it is quite rare to be able to take advantage of this.
The draft design drawing in front of him is just a small part of the technical outline he got from Xia Ke Academy.
As for the complete version of the technology, it will be gradually submitted to COMAC after the C919 project is restarted.
After taking two sips, he continued: "How is it? What I said this time about self-developed super-large civil aviation aircraft is true, right?"
"How confident are you that you can successfully develop it?"
This was the reason why he urgently approached Qin Huaichang for technical consultation. With COMAC's research and development capabilities, could it be possible to develop a super-large civil aviation aircraft of this level on its own?
"If subsequent design drafts are similar to this engine technology."
The smile on Qin Huaichang's lips never faded: "I am absolutely sure that I can successfully develop this C919 super-large civil aviation aircraft project by myself."
Although there are only a few dozen drafts, it is not difficult for Qin Huaichang, who has been studying the field of civil aviation for decades, to tell how authentic it is.
Apart from anything else, the level of detail of this super-thrust engine technology alone is not inferior to the integrated propulsion engine system provided by CFM.
"Then I'll feel relieved."
Hearing this solemn assurance, Xu Qianren finally let go of one of his worries.
Suddenly he remembered the scene when he took a flight back to the Magic City this morning.
Whether it was the flight he took or the various civil aviation aircraft parked at the airport, none of them were produced or developed by Daxia.
Xu Qianren began to murmur in his heart: 'Wait for Boeing and Airbus, our large aircraft that is 100% domestically produced and self-developed in Daxia is coming soon! ’
Just like the name COMAC919.
This is not as simple as just developing a large aircraft by ourselves. This is the will of Daxia and the expectation of the people. After sitting on the office chair for a long time, Xu Qianren remembered something.
Picking up the phone on the table: "Make an appointment with the representative of CFM's Daxia branch for me. I have urgent matters regarding the 'Integrated Propulsion Engine' contract that need to be negotiated."
on Monday.
It is still the conference room of Daxia Commercial Aircraft Administration Building.
Although Xu Qianren made an appointment with representatives of CFM's Daxia branch on Sunday, they still didn't arrive until Monday.
He didn't even come in the morning, but finally arrived at the conference room at around four o'clock, which was close to get off work time.
"Mr. Boden, the time we agreed on is obviously in the morning, and you are already seriously late." Xu Qianren frowned.
Charles Borden is the regional executive general manager of CFM in Daxia.
Not only was it as simple as being late, there were only three people in the entire team, one of whom was a translator.
This is a high-level contract negotiation, and the arrogance in it is evident.
"Xu, is there anything I need to add to the contract this time?"
Charles Borden raised a polite smile that was half-smiling: "Is it necessary to speed up the development and deployment of the integrated propulsion system LEAP-X engine?"
In his opinion, the biggest possibility that COMAC approached CFM this time was to speed up the development of the LEAP-X engine, which is the core of the C919 project.
An interpreter began to interpret the content.
Before Xu Qianren could reply, Charles Borden continued: "Xu, if you are looking for us for this problem, I'm really sorry. Our R&D personnel are too busy and the current R&D progress has reached the limit."
"You know, our CFM does not only have the LEAP-X engine project."
The implication behind his words is that if this time we are discussing accelerating research and development progress, then there is no need to discuss it.
Of course, there is another meaning, which is to add money.
Which developers are too busy? Are there more projects under development than just the LEAP-X engine?
Judging from the fact that the negotiation can be postponed for one day, it is not busy at all. It is clearly just an excuse. Adding money is the core meaning.
"Mr. Boden, you misunderstood. We have no objection to the development of your LEAP-X engine."
Xu Qianren didn't take it seriously at all and shook his head: "And that's not what needs to be negotiated this time."
Anyway, COMAC is not planning to purchase LEAP-X as an integrated propulsion system. You can develop it whenever you like.
"What other contract terms need to be negotiated?" Charles Borden was a little confused. CFM International had nothing else to offer except this?
However, Xu Qianren said something that he absolutely couldn't believe.
"The content of this negotiation" Xu Qianren suddenly changed his words: "No, it should be a notice that the cooperation framework that we, COMAC, and your CFM International Company have previously reached can now be cancelled."
Anyway, the contract has not been officially signed, it is just a preliminary memorandum of cooperation.
Now that Xu Qianren has officially notified CFM to cancel this cooperation framework, this is a very thorough consideration. Most other companies just ignore it.
However.
Listening to these words, Charles Borden looked puzzled: "WTF? Are you going to cancel the cooperation?"
I just want to increase the price. Why are you just flipping the table?
