Chapter 1206

The old chief teacher's words are not harmful, but very insulting!

What is hair dryer? Is it difficult that these aeroengine manufacturers do not even have a hair dryer? You know, they are aero-engine manufacturers, playing with top-level high-end manufacturing. They even say that they are not qualified to make hair dryers. It's not a slap in the face. It's a slap in the face with an iron hammer!

It's intolerable!

As a result, an impatient person in charge of the aeroengine manufacturing plant finally lost his patience. Before the old chief engineer finished his speech, he began to explain: "old chief engineer, your old saying is somewhat biased. We are the most technologically competent manufacturing enterprise in the domestic industry. How can we not even do a hair dryer well?

Not to mention that tengsen brand hair dryer uses injection technology, but more advanced technology. I believe that as long as you give me time, our factory can also make excellent products? "

"Old chief engineer ~ ~ ~ we know that you can't rub sand in your eyes, but we also need to know the actual situation of other domestic air launch units!"

The person in charge of the aviation development manufacturing plant, who was the first to speak, did not lose his voice. After all, the deputy director who managed to seize the opportunity, said immediately: "if other factories also have such opportunities as Tengfei group, I believe other aviation development manufacturing plants are no worse than anyone else. After all, their ability, technology and quality are there. What they lack is your authoritative recognition ！”

As soon as the deputy director said this, the heads of other air development manufacturing plants immediately nodded like chickens pecking rice. They looked confident and confident. They were really like the flow of failed draft candidates. It was not that they didn't work hard enough, but that they lacked a chance to get ahead!

"Is it?"

The old chief engineer did not get angry because of the affectation of the deputy director and others. Instead, he asked with a smile.

"That's true, old chief. I dare to assure you of my personality!" The person in charge of the aeroengine manufacturing plant who just gave an explanation immediately contacted us.

As a result, the general manager sneered and pointed to the tengsen brand hair dryer in his hand: "then you can try to make a batch of such hair dryers with T300 carbon fiber composite materials. If the price is controlled within 500 yuan, you still have 45% profit!"

"I This Old chief engineer Er... "

The person in charge of Hangfa manufacturing factory, who was facing the old chief engineer, listened to the old chief engineer's words and wanted to continue to explain, but he didn't know how to say it. He really didn't expect that these tengsen brand hair dryers in front of him were made of T300 carbon fiber composite materials.

What's more, I didn't expect that the hair dryer made of such advanced materials would still have 45% profit at the price of 500 yuan.

You know, 500 yuan is RMB, not US dollars. At this price, you can buy a few kilograms of T300 carbon fiber composites at most. Even the domestic materials produced by Tengfei group are only a dozen kilograms at most.

These things are connected, assembled, solidified, reworked, machined and assembled After a set of procedures, it is estimated that consumables alone will be more than 500 yuan. As a result, Tengfei group can guarantee 45% profit at this price. What does that mean?

In addition to being able to independently produce T300 carbon fiber composites and greatly reduce the cost, the most important thing is that Tengfei group has mastered the processing technology of carbon fiber composites in varying states, greatly simplifying the traditional process of manual bonding, cutting and assembling, and even directly applying more advanced mechanized mass production.

So as to greatly reduce the production cost of T300 carbon fiber composite materials, which can ensure profits!

In other words, rentengfei group has almost made T300 carbon fiber composite into cabbage price, and it can still get excess profit in cabbage price.

This is true of a small tengsen brand hair dryer, so is the wd-62mvp turbofan engine.

They are all old birds in the field of aeroengine manufacturing. The voice over of the commentary says venturi effect and injection technology. The directors of these aeroengine factories know the general structure of wd-62mvp turbofan engine.

In addition to the whole aero-engine, a shell similar to an external culvert is built.

In this way, when the engine absorbs air, the surrounding air can be absorbed at the same time, and the overflow temperature of the engine shell can be controlled in the air-cooled situation.

However, the principle of this structure is simple, but it is not easy to make it. Firstly, the material of the shell must be light, otherwise it will affect the total weight of the aero-engine, and then affect the thrust weight ratio;

secondly, the strength must be good enough. After all, it is an aero-engine component, even if it is only the shell, it also needs enough strength to ensure the overall structure of the engine Structure.

Finally, and most importantly, the cost must be controlled within a reasonable range. It can't be said that for the sake of performance, regardless of the cost, the unit price of aeroengine can be directly raised to the same level as that of ordinary combat aircraft. That's too much to be worth the loss.

Therefore, it is necessary to do a good job in cost control on the premise of ensuring the technology. This is not an ordinary high difficulty. The person in charge of the Hangfa manufacturing factory asked himself that his own factory can never do both.But Tengfei group did.

The low cost of tengsen brand hair dryer is just there. I can see how high the injection technology shell of wd-62mvp turbofan engine can be?

You should know that carbon fiber composite is the best material for this kind of shell. Since Tengfei group can greatly reduce the cost in the T300 composite processing plant, it will also have a good effect on the injection shell of wd-62mvp turbofan engine.

After all, the carbon fiber processing technology is a proper dual-use technology for military and civilian use, and it is only between the military and the civilian. In this case, how can the cost of the ejector housing of wd-62mvp turbofan engine be high?

Aware of this, the old face of the person in charge of the Hangfa manufacturing plant who came out to explain it was really red, orange, yellow and green. He was embarrassed to go back to his hometown. He was really embarrassed to go to grandma's home.

The deputy director of the Department is not much better, because the chief executive can't answer the question. He can't even control the cost of the hair dryer. How can he control the cost of the aeroengine?

On the other hand, can't they even make decent hair dryers? It's not that I don't work hard, but I just don't have a chance. Now the opportunity is in front of me. Let's first reduce the cost of the hair dryer made of carbon fiber composite materials. If you can't make it, don't force it!

However, when the old chief engineer once again talked about the happy conversation thoroughly, Zhuang Jianye quickly came out to make it over: "ah, old chief engineer, please calm down..."

Then he looked at the deputy director and others: "don't be hard on the old chief teacher, all my mistakes, all my mistakes..."

When he said this, Zhuang Jianye looked completely frightened, and then faced everyone: "otherwise, our ceramic matrix composite processing technology for the tail nozzle of wd-62mvp turbofan engine is willing to be transferred to our brother factory for free..."

As soon as they were ready to say two words of praise, Zhuang Jianye's next sentence completely broke them down: "however, this technology is currently the world's leading level, and only our group can produce the relevant equipment and raw materials. I can give the technology to the brother factories I want to take over for free, but the equipment and raw materials must be in our hands The group doesn't buy much here, and the one-time investment is only $70 or $8 billion.... "
