Chapter 579 I still got the 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 and has become a restricted aviation industry. Shortcomings in production output.
You know, Turbojet 14 and its derivatives are the current cash cow of Liming Group.
In this case, Lin Zuoming, the newly appointed general manager, simply decided to take advantage of the opportunity of developing the turbofan 10 to reorganize the entire casting section and transform it into a precision casting factory that integrates industry, academia, and research. The foundry center also hired some researchers with reliable backgrounds from Northeastern University and Liaoning University.
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 1990s, China's business community, of course the private business community, was still relatively wild and unruly.
The model of business war is often more inclined to war 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.
In this case, being able to find a stable and well-paid position in a large local 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."
Director of the Casting Center Ma Liping stretched out his arm, pointed at several huge pieces of equipment not far away that were five or six meters high, and introduced to Chang Haonan.
He was previously the deputy dean of the Research Institute of Materials Forming and Performance Control of Liaoning University, but unlike his colleagues who came here just for part-time work, Zhong Shihong used his research funding to be more than ten times higher than before. Digged here.
“Can this model 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 he calculates the parameters.
“It’s hard to say about the other older models, but the one you are looking at is the latest model. New linear motors and vacuum pumps have been installed on the belt drive shaft and pull-out device. I dare not say that in the world, At least it is definitely the best-performing equipment in Asia."
Ma Liping took out a technical manual from a nearby net pocket and handed it to Chang Haonan:
"The information on the nameplate. It’s quite limited. Mr. Chang, you can 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 other party’s linear motor was purchased directly from Torch-C.B. 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 was myself...”
However, at the moment, the business was about to begin. He did not spend too long on this technical manual:
“Since there is no problem with the equipment, in the next period of time, it is necessary 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, raised his head and looked 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?”
“You are producing older models, and the current production tasks are mainly for 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 has increased, the overall output has increased by about 3.5 times.”
Although Ma Liping has not been in Liming Factory for a long time. , but 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, and even Turbofan 9A has gone through the design finalization process. , ready for mass production.
Logically speaking, the business should be returned to Hao Jing.
After all, people almost live by this model.
Few turbojet 8s can be built every year.
"Well, we are responsible for the production of turbine discs, turbine blades and main shaft parts."
Ma Liping first entered the aviation industry system and didn't know much about the previous things. He just thought it was Chang Haonan who asked casually and helped him. After holding on to his safety helmet, he continued to answer:
“I heard that the order quantity of the turbofan 9A is very exaggerated. The Haofan side may not be able to produce enough production capacity at the moment, especially for hot-end components. block, so we can only entrust the production to us.”
“Is there such a large demand for the turbofan 9A?”
Rao Chang Haonan is responsible for this model to a certain extent. The design was finalized and trial produced, but I still felt 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 the electronic warfare aircraft before, and he was very clear about the production capacity of this aircraft.
Even if we work three shifts all year round, that’s still the level of about twenty fights.
This is the speed after the introduction of pulsating production lines.
It’s better not to let Haofa have a huge order.
Zhong Shihong, who had been silent just now, spoke up 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 I considered exporting it as FBC1, so I invited some military attachés from potential users to visit it. "
"Later, the aircraft was not sold, but the Persians felt that the power performance was good, so they went back. I accepted the F14AMC improvement plan previously proposed by Shengfei, which is to replace the turbofan 9, 1493 radar, and install the one with an open weapon interface..."
Watching flight shows and buying airplanes belongs to Persia It’s an old 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:
"The 1493 radar must be installed?"
1493 is the radar to be installed in the subsequent domestically produced improved J-11 plan , technically no different from the 1473 used in the J-10, but the caliber has 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, adjusted the working frequency band and target processing algorithm.”
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 basically have no Phoenix missiles on hand, so they are ready to let Those improved F14s can be directly mounted on the R33, which requires an open weapon interface and a radar with as much power as possible."
"Fuck..."
Chang Haonan uses one. Simple modal particles express one's mood at this time.
The R33 is a long-range air defense missile specially used by heavy interceptor aircraft during the Soviet period.
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 type 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 imaginary enemy training..."
Even Chang Haonan felt that it took some time to accept such explosive news:
“Forget it, let’s not mention the aircraft business for now, let’s continue talking about the current production situation... …”
