After all, the NB-233 laser additive equipment is the same as the "air car" special transport aircraft, which is a system for the aerospace department, and the high-performance composite materials developed by the Tengfei Aviation Technology Research and Development Center are basically in a little-known state, except for some academic papers that can be made public.

This is also an important reason why the Tengfei Group's "internal strength" cultivation has become more and more refined in recent years, but it has gradually contracted to the outside world, and it is not only to provide materials and equipment to the aerospace department, but also to participate in the production and manufacture of a new type of missile body, and the higher-level departments naturally have to reiterate their discipline.

However, there are also people who understand how much they can see the extraordinaryness of Tengfei Group, such as Song Changzheng, even if he refuses, he refuses politely, try not to offend Zhuang Jianye and Tengfei Group, if necessary, the first object of cooperation guarantees Tengfei Group, and never wants other semicolons.

The reason is very simple, that enterprise and institution has been able to hug the thighs of the troops so tightly over the years?

What is done is not pure military equipment, but the equipment supporting the subsidiary units of the army to support local construction, a year and a half is OK, the result of Tengfei Group has been working for several years, and the major projects have not fallen, even if Zhuang Jianye's reputation in the headquarters has slipped straight to the pile of dog skin plaster, but no matter how the leaders and heads of the headquarters change, Zhuang Jianye's Tengfei Group can always stabilize the share of the big contract foreman.

This treatment, even the own son of the headquarters is estimated to be unable to do it, how can Zhuang Jianye and his Tengfei Group do?

Quite simply, the headquarters is clearly to let the Tengfei Group make money, and spare no effort to give preferential policies, why is this so? Of course, the Tengfei Group has played an important role in other unknown aspects.

Fortunately, Song Changzheng didn't know, otherwise they would definitely be scared.

After listening to Zheng Yongning's brief introduction, they really thought that the NB-233 laser additive equipment was a special equipment purchased by Tengfei Group for the Tengfei Aviation Maintenance Factory, and its use was limited to the maintenance and repair of aircraft.

After all, when the small parts of many models are easily damaged and it is difficult to get a batch supply, it is still very cost-effective to use this equipment for temporary production.

However, if it is to be put into large-scale production and application, it is very unrealistic to use today's NB-233 laser additive equipment.

If nothing else, the workbench, which is not much larger than an ordinary black-and-white TV, limits the scope of application, and can only make parts within 15 cm, even a little larger will not work.

That's it, the key is that the production efficiency of NB-233 laser additive equipment is outrageous, Tengfei Aviation Maintenance Plant is indeed to complete part of the repair of low-pressure turbine blade strain crown work, but the total amount is only three, and the entire JT9D engine damaged the blade crown is as many as 16 pieces.

Based on the processing speed of NB-233 laser additive equipment to complete a leaf crown part in 32 hours, it will take half a month to say less than 16 pieces.

This kind of efficiency is passable in maintenance, but it is a bit touching if it is put on industrial large-scale production, because other production processes, although complex, can be mass-produced, so that efficiency and cost can reach a reasonable balance.

Speaking of cost, Wang Huan and others feel that NB-233 laser additive equipment is chicken ribs even if it is put on maintenance, not to mention the large power consumption, the cost of sensitive components is a sky-high price, and daily maintenance can only be described as a waste of money and labor.

If you look at the people in the whole workshop, you will know that there are thirty or forty people around a piece of equipment, and where is this posture of running equipment, it is simply serving the ancestors.

This made Wang Huan, who was originally surprised by the magic of this kind of technology, just gave birth to the introduction of thoughts, and was immediately cut off, the performance of Shanghai Airlines was not very good, the planes were not well maintained, and an ancestor went back, thinking about it is a little nervous.

Rather than this, it is better to give the maintenance package to the Tengfei Aviation Maintenance Factory, although the maintenance fee is a little more expensive, but it also does not have to bear the maintenance of special equipment and personnel, from this aspect, it seems that the airline side is more cost-effective.

Yes, after seeing the NB-233 laser additive equipment and the leaf crown manufactured by the equipment, Wang Huan's stereotype of Tengfei Aviation Maintenance Factory has completely changed.

After a series of analysis data about Ye Guan came out, Wang Huan was completely relieved, and felt that it was a good choice for the company's management to choose Tengfei Group as the outsourcer of the whole machine maintenance.

After waiting for lunch, Qiao Zhiming and Zheng Yongning took Wang Huan and his party around several other workshops, and Wang Huan's intention of handing over the aircraft maintenance to Tengfei Aviation Maintenance Factory was completely sincere.

Because whether it is electron beam welding equipment or precision imported machine tools, all of them are full of the word "professional", what else can be said about this? Naturally, I am very satisfied.

After Wang Huan returned to Shanghai and made a detailed report to Shanghai Airlines, the leaders of Shanghai Airlines came to inspect in person, and then signed a three-year aircraft professional maintenance agreement with a total value of 200 million yuan.

Tengfei Group's domestic aircraft maintenance business has finally opened up the situation while foreign giants are looking on the other side.

......

"Old Song, what's the matter, tell me quickly, I'm busy here. ”

Cotton City, Tengfei Aviation Power Company, next to a small flower bed next to a workshop.

Zhuang Jianye held the big brother in his hand, blocked the microphone with the other hand, and whispered to Song Changzheng on the other end of the phone.

As a result, Song Changzheng shouted disapprovingly: "Don't talk to me, I don't know you yet, on August 15, are you going to your father-in-law's house again?" ”

Hearing this, Zhuang Jianye almost didn't fall down, what did this cargo do you think of a plane? The stroller that his granddaughter was sitting in was neat, it was a Boeing 767, big brother.

"Okay, let's negotiate the price. ”

didn't hear Zhuang Jianye reply, Song Changzheng on the other end of the phone was a little anxious, and hurriedly urged.

Zhuang Jianye was a little embarrassed: "I said Lao Song, it's really inconvenient to be here today, shall we succeed another day?"

"It's not convenient, Zhuang'er~~ When are you so elegant, don't learn from the girls, just say that you don't give my brother this face. "Song Changzheng doesn't matter which one, he is the same as Zhuang Jianye, he belongs to the kind of faceless and skinless stalker.

Zhuang Jianye knows this better than anyone else, otherwise it would be impossible for the two of them to have a strange relationship during the national defense mobilization exercise, to put it bluntly, the two of them are almost the same-skinned, and no one can help anyone.

So at this time, how could Zhuang Jianye agree, otherwise this old man would definitely kick his nose in the face, so Zhuang Jianye suddenly fed ~~, and then fed in a series ~~ By the way, he patted the eldest brother, and scolded in annoyance, "MD, what is the broken signal!" and hung up the phone decisively in Song Changzheng's fierce shout.

Turning his head, his originally uncompromising face was immediately filled with a friendly smile: "Chief, some small things have made you wait for a long time." ”

The head of the headquarters waved his hand indifferently: "I know that you have a lot of business now, it's okay, we just took advantage of the holiday to come and have a look." ”

As he spoke, he pointed to the workshop in front of him: "The front is the production workshop of WD-30S?"

"Yes, yes......" Zhuang Jianye nodded again and again, and then gestured forward to the head of the headquarters and a large group of leaders of various troops: "Chiefs, ...... go this way."
