Take Off My Aviation Era

"Lao Huang, do you know how to speak, hold back if you can't speak, no one treats you as dumb!"

As soon as Huang Feng’s voice fell, Fang Yong, the head of the Northwest Aviation Plant, was unhappy. Before Zhuang Jianye could speak, he took Huang Feng back first, and then said with a serious face: "Why is Lao Zhuang? It's NM that was damaged to grandma's house, OK?"

"Puff~~"

He just drank a sip of the tea and sprayed Huang Feng, and immediately laughed: "Yes, yes, it is the Lao Fang's summary, the summary is in place!"

Zhuang Jianye could see it. These two are not good birds. The arrangement of people is more poisonous. If you change other people, you really can't take these two.

The boss of a Berjaya Group holds the No. 10 project, a high-quality production project; the other is the head of the Northwest Aviation Plant, the cradle of domestic transport aircraft and bombers.

It can be said that stomping can make the domestic aviation industry tremble.

But the problem is that Zhuang Jianye is not an ordinary person, so he coughed slightly: "ЗЛУ-24 vacuum electron beam welding machine, УВН-4500 large heat treatment furnace, ЛВ60 large X-ray irradiation machine, and 55,000-ton die forging from Ural Heavy Machinery Factory. Hydraulic press; 45,000-ton hot die forging press and 18,000-ton multi-directional die forging hydraulic press. I don’t think there is any need to split equally. Anyway, our Ascendas Group is short of these things, so we just stayed and took the -2000 well. This saves the industry from saying that Zhuang Jianye is bragging."

"Don't... don't... don't!" After hearing Zhuang Jianye's words, Fang Yong followed the cat that had stepped on its tail and hurriedly stopped them: "These things are all big guys. You have a place in the Ascendas Group. Is it? Let us help you share some of it."

"Yes, yes, yes..." Huang Feng also immediately agreed: "Lao Zhuang, I don't mean you, don't always carry -2000 out, okay, other people don't know, I and Lao Fang still don't know? A deceptive childcare, a fishing bait, but you Lao Zhuang took it seriously."

"Yes, it's just... you fool Lao Maozi and Lao Mei, but you still come to fool us, Lao Zhuang... Tonight Erguotou, Fenjiu, Xifeng, Wuliangye, Maotai will be like two or two, otherwise this pass will not pass. !" Fang Yong quickly made up for it.

Seeing two of the best in the domestic aviation industry playing rascals like a street gangster, Zhuang Jianye was also quite helpless. It didn’t matter if he was shameless, he actually met two shameless guys. That’s all. The problem is this. The two shameless people are actually right.

In fact, let alone the -2000 project, the WD-60ML-22 turbofan engine hung on the engine test bench is a deceptive support.

Because Ascendas Group has only mastered a part of the preparation technology of high-strength and high-toughness composite materials at best, and in this technological tree, epoxy resins and other chemical agents with fundamentally different proportions will form materials with different properties, precisely because of this. , Can be flexibly configured in different fields according to the properties of different composite materials.

This can not only optimize the performance of aerospace vehicles, but also control costs.

Take the US F-22 fighter jet. According to public information, nearly 25% of the composite materials are used on the fuselage, and most of them are special composite materials with high strength and toughness.

In fact, this kind of high strength and high toughness has a very obvious difference because of the difference in the position of the F-22 fuselage.

For example, the skin and side strips of the F-22 front fuselage use IM7\\5250-4 prepreg; the electronic equipment door uses IM7\\APC-2 prepreg; the internal frame and The fuel tank frame uses IM7\\PR500PTM prepreg; as for the air inlet, IM7\\977-3 prepreg is used.

Just one front fuselage uses four different composite materials. Although these composite materials are all reinforced with MI7 carbon fiber, the ratio of the epoxy resin at the back is different, which makes the final effect of the composite material different.

Some places simply need high strength and high toughness, some places both require radar wave penetration, some places require extremely high heat resistance, and some places are resistant to corrosion Sexually needs higher indicators...

These things need different epoxy resin ratios to achieve. The problem is that Ascendas Group currently only produces H-ZB800 composite materials, which are only equivalent to the IM7\\5250-4 type prepreg on F-22.

In other words, as far as Ascendas Group is concerned, it can only manufacture parts of the skin and edge materials of the new generation of combat aircraft. As for the composite materials of the internal frame, fuel tank frame, intake duct, tail, and electronic equipment door, Don't say that the Ascendas Group has it, it is still ignorant and directionless how to break through.

If this is not the case, the new generation of combat aircraft at this time is not a pre-research, but can be formally established. After all, the key composite materials have been obtained, combined with titanium alloy and aluminum-lithium alloy, and mass production is not dare to say, but one or two prototypes The machine will be available soon.

The reason why the pre-research project has not been formally established is that there is still a long way to go in many aspects.

This is true for the materials of the new generation of combat aircraft, and the same for the composite fan blades of turbofan engines. Ascendas Group can do, but it can withstand the impact of a 1kg bird at a relative speed of 200 kilometers at most. Living.

The composite blades equipped on the GE-90 used in the United States can withstand up to 6 kilograms of bird strikes.

No way, the American composite material uses IM7\8551-7 prepreg, which has invested heavily in research and development by General Motors. It is a high-strength\ultra-high-toughness composite material, which is comparable to the H-ZB800 composite material of Ascendas Group. The material is not a bit strong.

Because of this, the WD-60ML-22 turbofan engine is placed on the engine test bench. It’s okay to be a fudge. If it’s really installed on an airplane, it’s a big accident if something happens. After all, it’s more than 1 kg. There are so many birds, and the ones with relative speeds of more than 200 kilometers are pediatrics. I really want to hit them. That scene...

Even the genuine products on the engine test bench are flickering props, let alone the -2000 project drawn on the drawing board. To describe it in an unceremonious way, it simply means that there is no word at all.

Let alone the cutting-edge aviation aerodynamics technology in 2000, Ascendas Group did not fully grasp it. Even if the entire project enters the implementation stage of ~www.readwn.com~, Ascendas Group will have to stare at the drawings because of domestic manufacturers. Let's do it, let's not talk about the plane, it is impossible to make a common pivot inside.

There is no way, to process such things requires forging, and it cannot be the usual hot forging and die forging, but a precision forging process called multi-directional die forging.

And this process is the same as other forging processes, the stronger the forging equipment, the better.

The problem is that only a few domestic manufacturers have 100-ton multi-directional die forging equipment. This grade can process aircraft pivots up to 50 tons, and the performance is still unstable. Large aircraft with hundreds of tons cost at least 5000. Multi-directional die forging equipment over tons can be processed.

Such a large piece of heavy equipment is completely blank in China. Now it’s good. Zhuang Jianye flicked one-third of the real and seven-pointed fake, so he took one, and now it is used in the production of the Tu-204 passenger plane, and the Tu-160 strategic bomber was processed in the early years. The 18,000-ton multi-directional die forging hydraulic press originally produced by the Ural Heavy Machinery Factory with the variable sweep wing connected to the pivot was brought over.

Let alone Huang Feng and Fang Yong, it is just to make anyone in the aviation industry drool.
