Chapter 579: I still got F14

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

As the main manufacturer of Chinese aerospace engines, Factory 410 naturally had a casting section in the past.

However, both the technical level and the management model are no longer able to adapt to the production requirements of the new era.

Not to mention the third-generation turbofan engine, which requires more than one level of higher manufacturing precision, even in the production of castings for the turbojet 14, the efficiency has gradually failed to keep up with other processes, becoming a shortcoming limiting aviation engine production.

You know, Turbojet 14 and its derivatives are the current cash cow of Liming Group.

Under this situation, the newly appointed general manager Lin Zuoming simply decided to take advantage of the opportunity to develop the turbofan 10 to reorganize the entire casting section and transform it into a precision casting center integrating industry, academia and research. The university and Liao Provincial University have hired some researchers with reliable backgrounds.

Nowadays, it is the most prosperous time for university professors to have side jobs, but it is obvious that not everyone has the talent for business.

In the late 90s, China's business community, of course the private business community, was still relatively wild and unruly.

The model of business war also tends to favor war rather than business.

A shopping mall is literally a battlefield.

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.

Under such circumstances, being able to find a stable and well-paid position in a large local state-owned enterprise not far from home, even if subject to various restrictions on confidentiality regulations, is definitely very attractive.

Among the people who just attended the seminar, there were several with this background.

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

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

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

He was previously the deputy dean of the Institute of Materials Forming and Performance Control of Liaoning University, but unlike his colleagues who came here just for part-time work, he was poached by Zhong Shihong with scientific research funds that were more than ten times higher than before.

"Can this type of equipment meet the technical specifications for the production of single crystal turbine blades for third-generation engines?"

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

As far as the production process is concerned, equipment is the basis of all processes.

If the production equipment does not meet the requirements, it will be useless no matter how accurate the parameters are calculated.

"It's hard to say about the other older models, but the one you're looking at is the latest model. The belt drive shaft and pull-out device have been replaced with new linear motors and vacuum pumps. I can't say that it's the same in the world, at least in Asia. Best performing equipment.”

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

"The information on the nameplate is relatively limited. Mr. Chang, you can take a look at this for more details."

In fact, it is enough for the latter to get the answer just now. After all, there are specialties in the art industry. Although he specializes in more places, it is impossible to take over all the parts.

Equipment matters should still be left to people who specialize in hardware.

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

Then I discovered that the linear motor of the other party was purchased directly through Torch-CB Ferrari.

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 felt a little unexpected surprise:

"I didn't expect that the person doing the hardware would be myself..."

However, as he got down to business, he did not spend too long on this technical manual:

"Since there is no problem with the equipment, in the next period of time, we need to establish a model of the single crystal directional solidification process and then determine the process parameters."

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

After a moment of silence, he discovered that several pieces of equipment further away were probably in production. Only this latest model, perhaps because it had just been put in place, did not start up.

"Are you currently trial-producing turbine blades for Turbofan 10, or are you producing older models?"

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

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

"Are you still producing Turbofan 9?"

Chang Haonan was actually a little surprised when he heard what the other party said.

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

Logically speaking, the business should be returned to Hao Jing.

After all, people almost live by this model.

Only a few turbojet 8s can be built every year.

"Well, we are responsible for the production of turbine disks, turbine blades and main shaft parts."

Ma Liping had just entered the aviation industry system and didn't know much about what happened before. He just thought it was Chang Haonan who asked casually. After holding up his safety helmet, he continued to answer:

"I heard that the order quantity for the turbofan 9A is very exaggerated. Haofa probably doesn't have enough production capacity at the moment, especially the hot-end components, so they can only entrust us to produce them."

"Is there such a big demand for turbofan 9A?"

Although Chang Haonan was responsible for the design and trial production of this model to some extent, he still felt that it was too outrageous.

In his impression, the turbofan 9A model is only used on the JH-7A.

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

Even if there are three shifts all year round, that's still the level of about twenty fighters.

This is the speed after the introduction of pulsating production lines.

It's better not to let Haofa's side explode with orders.

Zhong Shihong, who had been silent just now, spoke at the right time:

“Last month, the second prototype of the JH-7A was equipped with a twin-engine turbofan 9A for flight testing. Because this model was considered for export under the name FBC1, some military attachés from potential users were invited to visit. "

"Later, the aircraft was not sold, but the Persians felt that the power performance was good, so they went back and accepted the F14AMC improvement plan previously proposed by Shengfei, which was to replace the turbofan 9, and the 1493 radar, and then installed the open The one with the weapon interface..."

Watching air shows and buying airplanes is an old Persian tradition.

This is what Pahlavi did when he bought those F14s.

However, Chang Haonan felt that Sheng Fei was playing a little too big this time:

"Does 1493 radar have to be installed?"

1493 is the radar planned to be installed on the subsequent domestically improved J-11. Technically, it is no different from the 10 used in the J-1473, but the caliber is increased by 200 mm, and accordingly the power and performance in all aspects have also been improved.

It is basically one of the most powerful mechanical scanning radars on the surface.

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

Because they are both in Shengjing and have very close business contacts, Zhong Shihong also knows a lot about Sheng Fei's situation:

"The main reason is that the Persians have basically no Phoenix missiles on hand, so they are planning to let the improved F14 directly mount the R33. This requires an open weapon interface and a radar with as much power as possible."

"Fuck..."

Chang Haonan expressed his mood at this time with a simple tone of voice.

The R33 is a long-range anti-aircraft missile specially used by heavy interceptors during the Soviet era.

But the phased array radar on the MiG 31, whose power and size are astonishing, has no chance of defeating the F14.

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

"In addition, I heard that in addition to the astonishing total amount of this upgrade transaction, the Persians also left 4 original F14s in good condition in our country for use as imaginary enemy training..."

Even Chang Haonan felt that it took some time to accept such explosive news:

"Forget it, let's not talk about the aircraft business for now, let's continue talking about the current production situation..."
