Chapter 677 Phased Array Radar
After a moment of silence, the chief took off his glasses with one hand and wiped them slowly:
“When I inspected Hufei in October last year, the responsible comrade told me that they were cooperating with the technical personnel of the Tupolev Group to assemble the first domestically produced C808 passenger aircraft. I wonder what the current progress is?”
Obviously, he has begun to mentally evaluate the prospects of domestically produced large early warning aircraft.
“Chief, Comrade Wan Shengren, the general manager of Hufei, submitted a report to me just the day before yesterday, and it happened to be about this aspect.”
Although he did not expect that the topic would involve Shanghai Aircraft Group before this trip, fortunately, the domestic passenger aircraft project is a top priority in Ding Gaoheng’s view, so there is no need to improvise:
“Prototype No. 01 of the C808 passenger aircraft assembled with large components has entered the final factory inspection stage. It is expected to roll off the assembly line in March and complete its first flight before the National Day at the latest. Prototype No. 02 is expected to be equipped with a pickaxe The domestically produced D436T1 engine assembled by China Development Group is expected to roll off the production line before the end of the year and make its first flight before February next year.”
“The C909 passenger aircraft has also completed technical modifications in accordance with my country’s aviation industry standards. Currently, Hufei has established a No. 2 project team, which is responsible for technical docking with Tupolev and the Perm engine production consortium. When the final assembly workshop is completed Then you can enter the production process.”
“As for the timetable…because it has not been officially put into production, there is no way to determine a very accurate project node for the time being. If we look at the efficiency of the C808, it should be able to complete its first flight before the end of 2001.”
In fact, the expectations reported by Hufei are a bit more optimistic.
But that’s what he was thinking just now, so he immediately stood up and responded:
“Yes, I will get started as soon as I return to the capital!”
“Can.”
“Let’s go down and talk.”
“The one on the early warning aircraft is actually quite good. It took about 14 months to complete production. Like the 346 Sea Star search radar that we are about to transfer to trial production, the antenna array box is 4 meters * 4 meters, and even It requires an additional tailor-welding step where the yield is not optimistic, and it is conservatively estimated that it may take more than 18 months to produce.”
“The chief means…”
It’s just that Ding Gaoheng couldn’t speak so rigidly in front of the big leaders, so he still left some margin for himself.
The chief nodded and agreed:
“However, if a report is to be produced, it should not be limited to the civil aviation industry.”
Wang Xiaomo explained:
The latter was a little surprised to be called on again, but he still trotted forward:
“Yes, especially the packaging of large-sized T/R components, because it is mainly done by hand and is very time-consuming.”
The chief put his glasses back on. Although he made no other movements, it could be seen from his happy expression that he was quite satisfied with the progress.
“After this key equipment is put into production, many aircraft structural parts that we could only import in the past, such as the body frame, landing gear, and central wing box of the C808 and C909, can gradually be made domestically. If you need it, sir, I will provide you with the relevant content. You can compile a report and submit it.”
The chief raised his hand and gently pushed up his black-rimmed glasses:
“Last year, when the Bi Sheng test ship was put into service, I heard from Comrade Shi Yunsheng of the Navy that the first test project after the ship entered service should be the shipborne radar you just mentioned?”
The chief stood up, led everyone out of the cabin, and returned to the apron. Then he turned around and waved to Wang Xiaomo, who had been pushed to a position slightly behind him:
At this time, Ding Gaoheng actually had some plans in mind, but in this case it was not easy to speculate casually:
“Yes, the Bisheng is currently undergoing adaptive changes in the shipyard and is preparing to install our first domestically produced ship-borne phased array radar.”
“Comrade Xiaomo, I remember you just said that domestically produced phased array radars are currently facing production capacity difficulties?”
Hearing this request, Ding Gaohengxin said that if it were a report on the entire aviation industry, I’m afraid you would see a name that appears very frequently in it…
When Ding Gaoheng saw this, he naturally struck while the iron was hot:
“This year happens to be the 50th anniversary of the founding of the People’s Republic of China. We can take this opportunity to summarize the achievements of China Aviation Industry in the past few years and submit it as a phased summary.”
“In addition, in the Equipment Industry Department of the Science and Technology Commission, the 70,000-ton heavy-duty hydraulic press developed under the leadership of Comrade Chang Haonan has also begun final assembly and is expected to be completed in the first half of this year.”
After all, both models are cooperating with the Tupolev Design Bureau. As both parties become familiar with each other, the efficiency will definitely improve gradually, rather than remain static.
“The plan is to be similar to the SPY1 radar used in the American Aegis system. After it is actually equipped on warships, each ship will install four sides at 90° to each other to ensure full 360° coverage of the surroundings. However, technically The active phased array route is more advanced in comparison.”
Hearing that the equipment was better than that of Americans, although the chief’s expression did not change, his tone became much lighter when he spoke:
“I remember a year ago, this model was said to be under development…and now it’s ready for trial production?”
Although Wang Xiaomo is not directly responsible for the 346 radar project, this matter is really closely related to him:
“The 14th Institute said before that it originally thought that the technology for large-size aluminum alloy tailor-welding would still take another stage to tackle, so the timetable was relatively loose.”
“But this time when we were working on early warning aircraft and cooperating with comrades in the aviation industry system, we heard that Shengjing already had experience in using inert gas shielded arc welding to weld large-sized aluminum alloy workpieces in order to produce heavy fighter jets, so we asked They went to provide guidance and solved a lot of problems.”
Although the 14th Institute of Electrical Engineering is also a military-industrial unit, it used to belong to the Ministry of Electronics Industry.
It is not the same system as the aviation industry, which is affiliated to the Commission of Science, Technology and Industry for National Defense.
That’s why there is a situation like “You have the technology I need, but we don’t know it”. Although we have joined the same family now, it is obvious that the cooperation between them cannot be established overnight.
It can be said that thanks to the opportunity to develop a domestic early warning aircraft, the progress of this project has entered the fast lane.
“So, if you want to increase the production speed of phased array radar, what do you need?”
The chief did not go around any more roundabout ways, but asked directly:
“In the future, we will need this kind of large-scale phased array radar in more and more places. It will definitely not work as it does now, and it will take more than ten months to build one.”
This problem is almost unnecessary for Wang Xiaomo to think about, because he is actually already thinking of a solution:
“In a short period of time… we can only recruit a group of more high-level technical workers. This is relatively easy to say, as long as the organization provides a certain number of establishments.”
“In addition, we have purchased a batch of brand-new CNC milling machines from Torch-C.B. Ferrari Group, which was just established last year. They are expected to be delivered in the second half of the year. Once put into use, we can change the current manual workshop model of production, and the efficiency will naturally increase. ”
“Torch…”
Torch Group is naturally famous among the big leaders.
After all, given the age of their general manager, it is difficult not to be noticed.
It’s just…
It seems that this is not the first time I heard the name Chang Haonan today…
…
The other side.
After meeting with Li Jie, Chang Haonan decided on a low-key sales strategy for Sugon 2000T.
Two days later, without any deliberate confidentiality or any publicity, the two parties signed an agency and dealer agreement, identifying Torch Group as the exclusive dealer of Dawn 2000T and the exclusive overseas dealer of Dawn 2000B.
Of course, the latter is just an addition.
Although the computing power of model B is slightly higher than that of model T, for foreign users, it is a technology two or three years ago, and there are no additional benefits. Even at a cabbage price, it is difficult to sell it.
“Professor Yang.”
In the conference room of Torch Group, Chang Haonan is deploying the sales strategy of the official version of TORCH Multiphysics software:
“Send a letter to all users who have tried our software and provided at least one valid feedback, telling them that they can get a long-term discount of 10% off the public sale price. In addition, if they subscribe for more than three years at a time, You can also add another 10% discount…”
In this regard, although he dare not say how professional he is, as someone who has seen various marketing strategies in the Internet era, even if he just comes up with some methods based on the gourd, it is definitely an exaggeration to say that it is shocking, but it is still eye-catching. Not a problem.
Just like Yang Huimei at this time.
She was writing furiously, writing down what Chang Haonan had just said in her notebook.
In a few years, the sales situation of TORC Multiphysics will no longer be a secret to Torch Group, and it can even become a classic case used in classes.
However, after finishing writing, Yang Huimei read it again from beginning to end, and then frowned slightly:
“Mr. Chang, didn’t you say before that you would keep a low profile this time?”
“We have hundreds of trial users who have given feedback, and we will notify them one by one… Isn’t that low-key?”
“What needs to be dealt with in a low-key manner is Sugon 2000T, which has nothing to do with our TORCH Multiphysics.”
Chang Haonan’s answer highlights a confident and confident answer:
“It would be better to say that the release of TORCMultiphysics should be more publicized, so as to hide it from others.”
“As for a special edition software that is bundled with a supercomputer, don’t let the public know about it yet. You can try it out by finding a few users who are more willing to buy, and it’s best to use the phone. way, so that the scope of the spread will be more controllable.”
“I see…”
Yang Huimei quickly agreed with Chang Haonan’s explanation:
“So do you already have candidates, or do you want me to pick some from user feedback?”
“Is this…”
Chang Haonan leaned on the wide backrest of the boss chair, raised his eyes to the sky and thought for a moment:
“It’s better to start from Maranello.”
“Ferrari won the constructors’ championship last year, and will definitely compete for the team and driver championships this year. There is an urgent need for this, and… they have deep pockets, and they probably don’t care about buying a supercomputer.”
