Chapter 733 Design finalization is not the end point
Snecma is the developer of the M88 engine used in the Rafale plan.
The core engine used by the M88 is still the CFM56, and heavily refers to the design of the F110 and F404 engines.
There are even quite a few parts directly operated by General Electric.
Including CFM56 itself, although it is nominally jointly developed by Snecma and General Motors, in fact the two are not equal at all.
For a long time, Rafale directly installed two F404s for flight testing.
Although the M88 has theoretically entered mass production, the stability of model A is very poor.
What is ready to be installed is Type B, which has been reduced in thrust and improved in anti-asthma performance.
It is still in the development stage.
But after GM withdrew its technical strength, it may be difficult to put it into service with the aircraft in 2001 according to the original schedule.
As for the purchase of F404...
Firstly, the sudden change of the engine of the mass-produced aircraft will cause the flight control that has been written to need to be rewritten. Secondly...
This wave of GM is obviously behind the scenes. At the behest of France, France was seeking revenge for its failure to bring down the euro and France's betrayal of taking the lead in the Allied campaign.
How could I sell you F404 so casually?
"Otherwise..."
Ziegler suddenly had a bold idea.
That person was just coming over to chat. After all, GM’s withdrawal was not a secret. It was just that Ziegler rarely got involved in military aircraft projects, so the information in this regard was not updated fast enough.
But now I heard that he seemed to have new ideas, and my eyes suddenly lit up:
"Do you have any alternatives?"
In fact, Ziegler What I was thinking just now was to either go to the British to purchase the EJ200 that will be put into service soon.
But after thinking about it, I feel that the nature of Dassault and Airbus is still different. The A330 can use the Trent 700, which does not mean that the Rafale can use the EJ200——
At that time, five European countries jointly developed the EF2000, and finally France People felt that those guys were really incompetent, so they finally set out on their own to work on Rafale.
Now you go back to the British to buy EJ200?
Even if someone else is willing to sell it, I’m afraid they can’t afford to lose face.
So making this suggestion is asking for trouble.
So he shook his head decisively:
"No...no, I just want to say that after all, Snecma has been involved in the engine field for many years, so there should be a solution."
The other party shrugged. :
"That's right...it's true. At most, it can only reduce the thrust a little bit...In short, the air force model is easy to say, but in this case, the navy type will be a little more troublesome..."
"..."
After some small talk, the man stretched out his hand towards Ziegler:
"Oliver Weiley, head of China Region of Dassault Aviation Civil Aircraft Department."
"Bernard De Ziegler.”
In the European aviation community, Ziegler does not need to state his title in most cases.
In fact, there are very few colleagues who don't know him. It's just a normal courtesy to say his name again.
"Speaking of which, your company's business volume in China...is so large that you need to set up a special region?"
Ziegler gave up trying to see something from the partition with the naked eye. He planned to simply turn around and start chatting with Wei Li.
“That’s not true, the China Region is just a shelf at the moment.”
Dassault’s Civil Aircraft Department mainly operates business jets and has basically no business overlap with Airbus, so the latter also There is no need to bluff, but to directly deny:
“Actually, up to now, we have not sold the first aircraft in China, but after the signing of the agreement last month, the above-mentioned requirements for China Business Jets We are very optimistic about the rapid development of the market, so we plan to send a few people over in advance to set up an office.”
……
At the same time.
Before letting the European delegation enter the production area to visit, the leaders on the Chinese side had naturally seen it once.
However, for the leader who came here in person this time, what he saw in the control room before was the focus, so he just walked around the equipment and took a few glances. The die forging press and several core responsible comrades from Jiang Zhong sat in a conference room.
“The workpiece that was just trial-produced should be part of the domestic fuselage of Project 11?”
Now this link is an internal discussion after the ceremony. In theory, it is not a very serious link. It is usually just a casual chat about what you just saw and heard. However, the leaders present this time are of different levels, so they cannot be too casual.
“Yes, Chief.”
The people next to them looked at each other a few times, and finally He Ming, who was in charge of the production and manufacturing of Project 11, opened the door. Mouth:
“The old models of Su-27 and J-11 used segmented casting and then welding in this part, but now they can be directly formed using the die forging process, which can shorten the processing time and reduce the weight of the parts. The structure and weight of the aircraft have great benefits.”
"Is this the technology provided by Sukhoi, or..."
Leaders with technical backgrounds made very detailed inquiries about technology research and development.
As soon as this question came up, He Ming immediately sat up straight:
“It is an improvement plan jointly finalized by us and Russian technicians within the framework of Project 11. Both parties share intellectual property rights!”
For a project that has only been introduced for three years, it is indeed quite rare to achieve this level.
Therefore, after listening to the report, the chief also seemed very interested:
“Then this should be regarded as...the first time in Project 11 that we have implemented technological feedback to Russia?”
"This...Strictly speaking, it doesn't count..."
He Ming subconsciously turned his head and glanced at Chang Haonan opposite:
"Previously, Mr. Chang, and the 14th Institute of Electronics The airborne jamming system developed by our comrades is also a reciprocal technology exchange with Russia in the name of aircraft ancillary equipment.”
The eyes of the leaders in the front row also turned to the latter.
Chang Haonan, who suddenly had the conversation falling on his head, quickly replied:
"Yes, it is actually the one installed on the JH-7. The Russian side wants to install it on them "We considered at that time that the potential of the JH-7 platform was really limited, so sooner or later our army's dedicated electronic warfare model would have to be transferred to the J-11 series. Now let Su Hoy gave it a try first, which would also help us reference in subsequent research and development, so he agreed to exchange this technology for an ion plating technology production line. The Turbofan 10 can produce a prototype so quickly, and this production line is also available. Credit.”
“But...”
At this point, Chang Haonan changed the subject:
“This matter is only operated in the name of Project 11 for convenience, but it actually has little to do with the aircraft itself, so strictly speaking, This aircraft structure upgrade carried out by Mr. He and the others can be regarded as a real first.”
Today’s gift itself has already attracted his attention, so there is no need to continue to compete at this stage. limelight.
Don’t eat alone.
As expected, the leaders’ attention returned to He Ming:
"I heard Comrade Li Liangxin report before that this year's National Day military parade will have an aerial formation of domestic third-generation fighter jets. Will the aircraft in it use the airframe components made today?"
"That's not the case."
He Ming slowly shook his head:
"We provided a technical demonstrator and two first-stage prototypes to the 9910 project, but for the To ensure the stability of the aircraft, it is determined that there are no problems after a relatively long period of flight testing.”
“Although the J-11B prototype is expected to be completed before the National Day, it is a new structure with new power after all. , without enough time for stability testing, it is still not easy to go directly to the military parade.”
One good thing about leaders who understand technology is that they respect objective laws, so they easily accept such explanations.
“Comrade He Ming just talked about the new power.”
He looked at Chang Haonan again:
“Comrade Chang Haonan, in more than a month, aviation power will The group company is about to be officially established. As the specially appointed chief planner, do you have any specific ideas for the business development of the new group? "
Hearing this question, He Ming opposite and next to him asked. Lin Jingtang's whole body trembled obviously.
If there weren't so many leaders on this occasion, I'm afraid they would all have to shout out——
Chang Haonan did say before that he had found a position in the newly established Aviation Development Group.
But the position you are talking about directly has the word "general" in it?
And this is a proper second-level central enterprise, the chief planner, if he is a member of the leadership team...
The level is a bit scary.
However, Chang Haonan's attention will definitely not be on these two people at this time.
The big leader spoke, and he must take this opportunity to shake off the plan in his mind:
“After the group is established, the first priority will of course still include the turbofan 10. After all, the finalization of the design of several new models of engines is regarded as the first battle after the formation of a separate aviation power force."
"As for the next step, I have mainly arranged two key directions."
"First of all. It is a training opportunity to further develop the Turbofan 10 project, allowing comrades from various units who have participated in the research and development of the Turbofan 10 to return to their posts and make necessary technical upgrades to some of our country’s existing engines with older technology but large installed capacity. .”
"On the other hand, for the Turbofan 10 model itself, the design finalization is by no means the end, but a new starting point. Currently, this model is still subject to several key processes, resulting in relatively limited production capacity, which may even affect The production scale of my country's two types of third-generation fighter jets will increase in the future, so I personally plan to continue to lead the team to tackle the problems of insufficient production efficiency and yield rate! ”
