The Military-industrial Scientific Research System of the Academic Master Chapter 733

Chapter 733 Design finalization is not the end

Snecma is the developer of the M88 engine used in the Rafale project.

   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.

  However, after GM withdraws its technical strength, it may be difficult to enter service with the aircraft in 2001 according to the original schedule.

 As for purchasing F404…

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.

 So making this suggestion is asking for trouble.

“That's right... that's what I said. 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..."

 “Bernard Ziegler.”

This wave of GM is obviously under the instruction of the big boss behind the scenes to retaliate for failing to bring down the euro and France's betrayal of taking the lead in the Allied Forces operation.

At that time, five European countries jointly developed the EF2000. In the end, the French felt that those guys were really not good enough, so they finally independently developed the Rafale.

 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.”

 Firstly, a sudden change of engine for a mass-produced aircraft will cause the already programmed flight control to need to be rewritten, and secondly...

 But now that I heard that he seemed to have a new idea, my eyes suddenly lit up:

 “Do you have any alternatives?”

 In fact, there are very few colleagues who don't know him. It's just a normal courtesy to say his name again.

How could I sell you F404 casually?

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—

 In fact, what Ziegler just thought was to simply go to the British to purchase the EJ200 that will be put into service soon.

 After some small talk, the man stretched out his hand towards Ziegler:

“Oliver Weili, Head of China Region, Dassault Aviation Civil Aircraft Division.”

In the European aviation community, Ziegler is not required to state his title in most cases.

The other person shrugged:

 “Otherwise…”

 Ziegler suddenly had a bold idea.

Now you go back to the British to buy EJ200?

Even if someone else is willing to sell it, I can't afford to lose face.

"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 on trying to see anything from the partition with his naked eyes, and simply turned around to chat with Wei Li.

“That's not true. The Huaxia Region is just a shelf at the moment.”

 Dassault Civil Aircraft Department is mainly engaged in business jets and has basically no business overlap with Airbus, so the latter does not need to bluff, but directly denies:

"Actually, so far, we have not sold the first aircraft in China. However, after the signing of the agreement last month, the higher-ups are very optimistic about the rapid development of China's business jet market, so we plan to send a few people over in advance. Establish 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. At this time, he was already talking to the die forging press and Jiang Zhong. Several core responsible comrades here sat in a conference room together.

“The workpiece that was just trial-produced should be part of the domestic fuselage of Project 11?”

This session now belongs to the internal discussion after the ceremony. In theory, it is not a very serious session. It is usually just a casual chat about what we just saw and heard. However, the leaders present this time are of different levels, so we should not be too casual.

 “Yes, Chief.”

Several people nearby looked at each other, and finally He Ming, who was in charge of the production and manufacturing aspects of Project 11, spoke:

"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 has a great impact on shortening the processing time and reducing the weight of the body structure. benefit."

“Is this the technology provided by Sukhoi, or...”

 Leaders with technical backgrounds will ask very detailed questions 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 No. 11, and 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 of success.

 Therefore, after listening to the report, the chief also seemed very interested:

“Then this should be regarded as...the first time we have implemented technological feedback to Russia in Project No. 11?”

 “This…strictly speaking, it doesn't count…”

He Ming subconsciously turned his head and glanced at Chang Haonan opposite:

“Previously, Mr. Chang and the comrades of the Electronics 14th Institute developed an airborne jamming system, which was also a reciprocal technology exchange with Russia in the name of aircraft ancillary equipment.”

 The eyes of several leaders in the front row also turned to the latter.

Chang Haonan, whose words suddenly fell on his head, quickly replied:

“Yes, it is actually the one installed on the JH-7. The Russian side wants to install it on their new tactical bomber platform.”

"We considered at that time that the potential of the JH-7 platform was really limited, so our military's dedicated electronic warfare models would sooner or later be transferred to the J-11 series. Now letting Sukhoi try it first will also help us in subsequent research and development. We needed to make reference at that time, so we agreed to exchange this technology for an ion coating technology production line. The fact that the Turbofan 10 prototype was able to be produced so quickly was also due to this production line.”

"but…"

 Speaking of this, Chang Haonan changed the subject:

"This matter is only operated in the name of Project 11 for convenience, but in fact it has little to do with the aircraft itself, so strictly speaking, this aircraft structure upgrade carried out by Mr. He and his team can be regarded as a real aircraft for the first time.”

Today's gift itself has already attracted him a lot of attention, so there is no need to continue to steal the limelight in this session.

　　Do not eat anything alone.

As expected, the chiefs' attention returned to He Ming:

“I heard a report from Comrade Li Liangxin before, saying 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?”

 “This is not the case.”

He Ming slowly shook his head:

“We have provided a technical demonstrator aircraft and two first-stage prototype aircraft to the 9910 project. However, in order to ensure the stability of the aircraft, they have been tested for a relatively long time and there are no problems.”

“Although the J-11B prototype is expected to be fully assembled before the National Day, it is a brand-new structure with brand-new power, so it is not easy to go directly to the military parade without enough time for stability testing.”

 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 a new impetus.”

 He looked at Chang Haonan again:

“Comrade Chang Haonan, in more than a month, the Aerospace Power Group Company will 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 Lin Jingtang next to him trembled visibly.

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...

 Level is a bit scary.

However, Chang Haonan's attention will definitely not be on these two people at this time.

 The big leader has spoken, and he must take this opportunity to shake out the plan in his mind:

“After the establishment of the group, of course, the first priority is to finalize the design of several new types of engines, including the Turbofan 10. After all, it is the first battle after the formation of a separate aviation power force.”

“As for the next step, I have mainly arranged two key directions.”

"The first is to further utilize the training opportunities of the Turbofan 10 project, and allow comrades from various units who have participated in the research and development of the Turbofan 10 to return to their posts and conduct necessary training on some of our country's existing engines with older technology but large installed capacity. Technology upgrade.”

"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 In the future, my country will produce two types of third-generation fighter jets, so I personally plan to continue to lead the team to tackle the problems of insufficient production efficiency and yield rate!”
