Take Off My Aviation Era

, The fastest update to take off the latest chapter of my aviation era!

The curse in Zhuang Jianye's heart, Lin Guanghua's rammer, why did you tell Ding Laixiang everything, is the old man your father?

But think about it, there is really no difference between the tutor of graduate students and my father these years.

Yes, the two sets of equipment proposed by Ding Laixiang are really owned by Tengfei Factory. They were imported from West Germany not long ago, and these two sets of equipment are worth more than three million US dollars, which almost consumed Tengfei's annual foreign exchange quota. one third.

When Zhuang Jianye made this decision, he almost broke his teeth. There was no way. This was the largest external procurement project ever made by Ascendas Factory. It was more than three million U.S. dollars, which is almost the sum of the profits of electric fans in two years. It's definitely a lie to say it doesn't hurt.

But even if it hurts, Zhuang Jianye bought it. The reason is simple. The small jet engine in the factory has entered a critical stage.

When it comes to the jet engine research and development organization of the Ascendas Plant, it is no longer the grass-roots team that Master Ju and Liu Chun privately collected. Now it has an exact name called the Ascendas Plant Jet Power Office.

As for the director of the office, it is neither Liu Chun nor Master Ju, but Yan Tiancheng, the former director of the trial production office of Yonghong Factory and the old superior of Zhuang Jianye, who just retired from Yonghong Factory not long ago.

When Zhuang Jianye was in the trial production, Yan Tiancheng's head was sharpened and his mind went up. In the trial production day by day, he talked about politics more than technology, so that people think that this old guy is a layman leading an expert bureaucrat. In fact In his early years, Yan Tiancheng was one of the few technical backbones at Yonghong Plant who had a full set of experience in the trial production of turbojet engines and turbofan engines.

Even today, his experience and technology are not comparable to ordinary people, and even in this life there is no way to compare it. Starting from Turbojet 6, Turbojet 7, Turbofan 6, "Speey" MK202, and even the border crash Reverse mapping of high-power turbofan engines on large airplanes.

Yan Tiancheng did not simply participate, but went through all the processes completely, not just one, but several.

This is incredible. There are so many domestic aero engines, Yan Tiancheng has done almost all of them, and they are simply precious.

In fact, Yonghong Factory really regards him as a treasure. The reason why he was involved in the aero engine process back then was to cultivate the technical backbone and leading cadres for the future aero engine production.

However, Yonghong Factory did not compete and lost the opportunity to produce engines, but even so, Yan Tiancheng was reused and became the leader in the trial production of iron tails.

Under normal circumstances, Yan Tiancheng would be promoted to deputy factory director and then retired from the factory's party committee. Unfortunately, after a series of transformations in the Yonghong factory, young cadres began to be promoted. Old cadres like Yan Tiancheng began to be gradually marginalized.

At the end of last year, he formally stepped down as the director of the trial production office and was assigned to a second-line position as a leader. This year Wang Wei became a demon, and Yan Tiancheng was implicated and retired early.

Upon receiving this news, Liu Chun and Master Ju, who often blow up engines, came to the door immediately and worked hard for more than half a month. At last they invited the old baby to come back out of the mountain and re-employ the Ascendas factory as the newly established jet engine office. director.

The new official will naturally burn three fires when he takes office. Instead of being a bureaucrat, Yan Tiancheng's three fires are very prosperous. The first is to criticize Liu Chun and Master Ju, even a little bit of common sense of system integration. If you don't have one, you dare to use jet power for drones. It's almost like death, and you're still talking about saving money. Is jet power a money-saving thing?

The second is to go back to the Yonghong factory, find a lot of people who have been doing the trial production, and tell them that they are idle when they are idle. It is better to help him with the trial production, and it is not in vain. The old leaders have been seeking benefits for them.

Yan Tiancheng, the director of the trial production office who has been working for seven years, has the prestige of the trial production office that is within reach. In addition, he backs the Tengfei Factory, a cash cow, and throws a lot of banknotes. Yan Tiancheng's trial production task will begin in the next moment.

After that, I found Zhuang Jianye, an old subordinate, and politely took out a lot of purchase lists and bills. Zhuang Jianye's eyes were dizzy.

He also said to Yan Tiancheng politely: "Can we save a little bit?"

Yan Tiancheng smiled brightly: "This is already the most economical."

Yes, the list given by Yan Tiancheng is staggeringly expensive, but it is indeed the most economical plan that the old man has deliberated on. Even the electron beam welding machine and high-speed hydraulic cutting machine worth more than three million US dollars are also key equipment that has to be used. .

Although the jet power of a drone is less technically difficult than a high-thrust jet engine, but if you want it to have a long service life, in fact, there are not many difficulties.

Titanium alloy should be used for titanium alloy, and for heat dissipation, heat dissipation is also required. Let's say that Yan Tiancheng chooses the two components of the engine combustion chamber turbine cover and fan cover.

That is the material on the proper high-power turbojet engine. In order to achieve high-temperature resistance, the surface is sprayed with ceramic coatings of various high-temperature alloys and carbides.

Because of this ceramic coating, the material has a very high rate of damage during cutting, because ordinary mechanical cutting, due to inevitable vibration and inherent accuracy problems, causes the material to either be sprayed and fall off, or the accuracy after processing is poor Rework is required to meet the standards.

Advanced laser cutting has no concerns about vibration. Unfortunately, the laser cuts through high temperature. The ceramic coating on the material is just a good high-temperature insulator, so laser cutting is equivalent to a heat resistance test for the material. .

Only high-speed hydraulic cutting can solve these problems, not only can cut the material, but also ensure the accuracy.

In Yan Tiancheng's words: "In the early years, we closed ~ www.readwn.com~ I didn’t know that high-speed hydraulic cutting was available abroad, which made us worry about the materials and cannot do large-scale industrial production. No matter how good the materials are, it’s useless. , Turbofan 6 is so absent, so, Xiaozhuang, if you want to use turbojet on the drone, this is something you must do."

High-speed hydraulic cutting is indispensable, and electron beam welding machines are even more indispensable. Because Yan Tiancheng changed the conservativeness of Liu Chun and Ju masters, and used titanium alloy for the key components in the turbojet engine of the Ascendas plant. Low-carbon alloy steel, and the best welding method for titanium alloy is electron beam welding.

Zhuang Jianye is not someone who doesn't know how to do it. The two equipment that Yan Tiancheng wants is not to mention the present, and they will also be indispensable key equipment in the aviation field in the future. Since they are useful, they were bought for more than three million US dollars.

But I didn’t expect that when he hit him, he hit Lao Ding with red eyes. Seeing this, Professor Ding Da wanted to copy Director Yan Da’s bullishness and scorned himself. The problem is that Tengfei’s money is not. Is the vacuum brazing device not enough because of the strong wind?

So after thinking for a while, Zhuang Jianye looked at Professor Ding with a look of embarrassment: "Professor Ding, I think Guanghua has also told you that the two equipment are not only expensive, but also not easy to buy. Ascendas has provided such a set. I have the strength to eat milk, and it is unlikely to get a second set. Do you think this will work? You can ask Professor Qian to take people to me, and use the equipment as you want...
