After the seminar, Chang Haonan asked Zhong Shihong to take him to the new precision casting center set up by Liming Group for the turbofan 10 project.

As the most important manufacturer of Huaxia Aero Engine, the 410 factory in the past naturally also had a casting section.

However, both the technical level and the management mode are not quite able to adapt to the production requirements of the new era.

Not to mention the third-generation turbofan engine, which requires more than one grade of manufacturing accuracy, even the production of turbojet 14 castings, the efficiency has gradually failed to keep up with other technological processes, which has become a short board that limits the output of aviation engine.

You must know that Turbojet 14 and its derivatives are the cash cow of Dawn Group today.

In this case, Lin Zuoming, the newly appointed general manager, simply made a decision, and took advantage of the opportunity to engage in turbofan 10 to reorganize the entire casting section and transform it into a precision casting center with the nature of production, education and research, and also hired some researchers with reliable backgrounds from Northeastern University and Liaoning Provincial University.

It's the time when college professors have the most popular side hustles, but it's clear that not everyone has the talent to run a business.

At the end of the 90s, the business community in China, of course, refers to the private business community, which was still relatively wild and uninhibited.

The mode of business warfare is also often more inclined to war than business.

Literally, shopping malls are like battlefields.

Especially for some science and engineering scholars who have lived on campus for a long time, going out to do business is almost equivalent to giving money to others.

In this case, it is absolutely attractive to be able to find a stable position in a large local central enterprise not far from home, even if it is subject to various restrictions on confidentiality.

Several of the people who attended the seminar just now came from this way.

Judging from the feedback from the people on the scene, their theoretical foundation and understanding of modern technology are indeed much better than their peers who have been working in the production line of the factory for a long time.

"Mr. Chang, these are the directional solidification furnaces that we have only purchased from Shengjing Scientific Instrument Company in recent months, replacing the extensive equipment in the past and used for the production of turbine blades."

Ma Liping, director of the Foundry Center, stretched out his arm and pointed to several huge equipment not far away, which were five or six meters high, and introduced to Chang Haonan.

He used to be the vice president of the Institute of Material Forming and Performance Control of Liao Provincial University, but unlike his colleagues who only came to work part-time, he was poached by Zhong Shihong with scientific research funds that were more than ten times higher than in the past.

"Can this type of equipment meet the technical specifications for the production of monocrystalline turbine blades for the third generation engine?"

Chang Haonan circled around the equipment and finally stopped in front of the equipment nameplate.

When it comes to the production process, the equipment is the basis of all processes.

If the production equipment does not meet the requirements, it is useless for him to calculate the parameters accurately.

"It's hard to say about the other old models, but the one you're looking at is the latest. With new linear motors and vacuum pumps for belt shafts and pull-out devices, it is certainly the best equipment in the world, at least in Asia. ”

Ma Liping said and took out a technical manual from a net pocket next to him and handed it to Chang Haonan:

"The information on the nameplate is relatively limited, so you can take a look at this and be more detailed."

The latter is actually enough to get the answer just now, after all, there is a specialization in the art industry, although he has more specializations, it is impossible to take all the parts together.

The equipment is still to be handed over to someone who specializes in hardware.

But since the other party had already said so, Chang Haonan still took it and flipped it over.

Then it was discovered that the other party's linear motor was purchased directly through the Torch-C.B. Ferrari company.

The model is exactly the same as that used on the MS45T three-axis machining center.

Chang Haonan shook his head helplessly, but at the same time, he had some unexpected surprises in his heart:

"I didn't expect that the person who was engaged in hardware turned out to be myself......"

However, he didn't spend too much time on this technical manual at the moment:

"Since the equipment is fine, it is necessary to establish a model of the directional solidification process of the single crystal in the next period of time, and then determine the process parameters."

Chang Haonan put the manual back in the bag next to him and raised his head to look at the equipment in front of him.

After a moment of silence, he noticed that several devices further away should be in production, only this latest model, probably just in place, and not activated.

"Are you trying to make the turbine blades of the turbofan 10 now, or are you producing the old model?"

"In the production of old models, the current production tasks are mainly turbofan 9 and turbojet 14, compared with the past when it was only a casting section, because the number of blades that can be produced in each batch has increased, so the comprehensive output has increased by about 3.5 times."

Although Ma Liping has not been in the Liming Factory for a long time, he is obviously familiar with business matters.

"You're still producing turbofan 9?"

Hearing the other party's statement, Chang Haonan was really a little surprised.

Although he has always regarded the turbofan 9 as a verification project for the technical and process testing of the turbofan 10, the verification that can be verified on it has long been completed, and even the turbofan 9A has gone through the design finalization process and is ready for mass production.

It stands to reason that the business should be returned to Ho Kyo's side.

After all, people almost point to this one model to live.

Turbojet 8 simply can't build a few units per year.

"Well, we are responsible for the production of the turbine discs, turbine blades and spindles."

Ma Liping first entered the aviation industry system, but he didn't know much about the previous things, but Chang Haonan asked casually, and after holding the helmet, he continued to answer:

"I heard that the number of orders for turbofan 9A is very exaggerated, and the pickaxe side should not be able to get enough production capacity for a while, especially the hot end parts, so it can only be entrusted to us for production."

"Is there such a large demand for the turbofan 9A?"

Rao is Chang Haonan to some extent single-handedly presided over the design finalization and trial production of this model, but he still felt that it was too outrageous.

In his impression, the turbofan 9A model was only used on the J-7A.

But he had inspected the production line when he had changed to an electronic warfare aircraft before, and he was very clear about the production capacity of this aircraft.

Even if there are three shifts a year, that is, the level of more than 20 planes.

This is still the speed after the introduction of the pulsating line.

It's not enough to let the pickaxe explode orders.

Zhong Shihong, who had not spoken just now, opened his mouth at this time:

"Last month, the second prototype of the J-7A was equipped with a twin-engine turbofan 9A for flight testing, because this model was considered to be exported under the name of FBC1, so some military attachés of potential users were invited to visit at that time."

"Later, the plane was not sold, but the Persians felt that the power performance was good, so they went back and accepted the F14AMC improvement plan proposed by Sheng Fei's side, that is, to replace the turbofan 9, and the 1493 radar, and then install the ...... of the open weapon interface."

Watching air shows and buying airplanes belongs to the old Persian tradition.

That's how Pahlavi did it when he bought those F14s back then.

It's just that Chang Haonan feels that Sheng Fei seems to be playing a bit big this time:

"The 1493 radar is going to be installed?"

1493 is the radar installed in the follow-up domestic improved J-11 plan, which is technically no different from the 1473 used in J-10, but the caliber has increased by 200 mm, and the power and performance in all aspects have also been improved.

It's basically one of the strongest mechanical scanning radars on the surface.

"Export type, adjusted the working frequency band and target processing algorithm."

Because they are in Shengjing and have a very close business relationship, Zhong Shihong also knows a lot about Shengfei's situation:

"The main thing is that the Persians basically don't have the Immortal Bird missiles at hand, so they are ready to let those improved F14s directly hang the R33, which requires an open weapon interface and a radar with as much power as possible."

"What the ......"

Chang Haonan used a simple tone word to express his mood at this time.

The R33 is a long-range anti-aircraft missile designed for heavy interceptors during the Soviet era.

But the phased array radar on the MiG-31, which is shocking in power and size, is absolutely impossible to scare the F14.

Then the export version of the 1493 is indeed the only option left.

"In addition, I heard that in addition to the total amount of this upgrade deal is quite amazing, it also includes the Persians leaving 4 original F14s in good condition in our country as training ...... imaginary enemy."

Such explosive news even Chang Haonan felt that it took a little time to accept:

"Forget it, let's not talk about the business on the plane side, let's continue to talk about the current production situation......
