"Lao Huang, you can't speak, if you can't speak, hold back, no one treats you as a dumb person!"

As soon as Huang Feng's voice fell, Fang Yong, the head of the Northwest Airlines Plant, was not happy, and before Zhuang Jianye could speak, he took the first step to scare Huang Feng back, and then said with a straight face: "How is Lao Zhuang damaged? ”

"Poof~~"

As soon as he took a sip of tea, Huang Feng sprayed it directly, and immediately laughed: "Yes, yes, it's still the old party's summary in place, and the summary is in place!"

Zhuang Jianye can see that these two people in front of him are not good birds, and they are more poisonous than the other, if they change to others, there is really no way to take these two.

The boss of a successful group holds the high-quality production project of Project 10 in his hands, and the other is the head of the Northwest Aviation Plant, the cradle of domestic transport aircraft and bombers.

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

But the problem is that Zhuang Jianye is not an ordinary person, so he coughed lightly: "ЗЛУ-24 vacuum electron beam welding machine, УВН-4500 large heat treatment furnace, ЛВ-60 large X-ray irradiation machine and 55,000 tons of die forging hydraulic press of Ural Heavy Machinery Factory, 45,000 tons of hot die forging press and 18,000 tons of multi-directional die forging hydraulic press, I don't think there is any need to divide it equally, anyway, we Tengfei Group is lacking these things, just stay, put FCNB- 2000 good bargaining, saving the industry always said that I Zhuang Jianye braggart. ”

"Don't ...... Other...... Don't!" Hearing Zhuang Jianye's words, Fang Yong hurriedly stopped the cat who stepped on his tail: "These things are all big guys, do you have a place to put them in Tengfei Group?" ”

"Yes, yes, yes......" Huang Feng also immediately agreed: "Lao Zhuang, I didn't mean you, don't always carry FCNB-2000 out, others don't know, I and Lao Fang are still not clear? That's a deceitful nursery, fishing bait, but your Lao Zhuang is still serious." ”

"That's it, that's it...... You fool Lao Maozi and Lao Mei, even if you fool Lao Maozi and Lao Mei, you still come to fool us, Lao Zhuang...... Tonight, Erguotou, Fenjiu, Xifeng, Wuliangye, and Moutai will come to two taels, otherwise this pass will not be passed!" Fang Yong hurriedly made up for it.

Seeing that the two top two bigwigs in the domestic aviation industry are like scoundrels on the street, Zhuang Jianye is also quite helpless, even if he is shameless, he actually met two even more shameless ones, that's all, the problem is that these two shameless people are actually right.

In fact, not to mention the FCNB-2000 project, even the WD-60ML-22 turbofan engine hanging on the engine test bench is a cover-up.

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

This not only optimizes the performance of aerospace vehicles, but also controls costs.

Take the American F-22 fighter jet as an example, public information says that nearly 25% of the composite materials are used in the fuselage, and most of them are special composite materials with high strength and high toughness.

In fact, this kind of high strength and high toughness are very different because of the different positions of the F-22 fuselage.

For example, the skin and edge strips of the front fuselage of the F-22 are made of IM7\5250-4 prepreg, the electronic equipment door is IM7\APC-2 prepreg, the internal frame and fuel tank frame are IM7\PR500PTM prepreg, and the intake duct is IM7\977-3 prepreg.

The front fuselage alone uses four different composite materials, although these composites are reinforced with MI7 carbon fiber, but the ratio of epoxy resin in the back is different, so that the final effect of the composite materials is different.

Some places simply need high strength and high toughness, some places need to have both at the same time, radar wave penetration, some places require extremely high heat resistance, and some places need higher indicators in corrosion resistance......

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

In other words, with the current mastery of the Tengfei Group, it can only be the manufacturing technology of the skin and edge strip materials of the new generation of combat aircraft, as for the composite materials of the internal frame, fuel tank frame, air intake, tail, electronic equipment doors and other parts, the Tengfei Group does not have it, but it is still ignorant and has no direction on how to break through.

If not, 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 are made, with titanium alloy and aluminum-lithium alloy, mass production dare not say, but one or two prototypes can still be made quickly.

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.

The materials of the new generation of combat aircraft, as well as the composite fan blades of turbofan engines, can be done by Tengfei Group, but the things made can withstand the impact of a bird with a size of 1 kilogram at a relative speed of 200 kilometers, and no matter how big it is, it will not be able to withstand it.

The composite blades on GM's GE-90 can withstand up to 6 kilograms of bird impact.

There is no way, the composite materials of the Americans use IM7\8551-7 prepreg that General Motors has invested heavily in research and development, which is a high-strength \ ultra-high toughness composite material, which is not a little stronger than the H-ZB800 composite material of Tengfei Group.

Because of this, the WD-60ML-22 turbofan engine is placed on the engine test bench, and it is okay to fool people when it is a showcase, and it is really installed on the plane, and if there is no accident, it is a big accident, after all, there are more birds than 1 kilogram, and the relative speed of more than 200 kilometers is pediatric......

Even the real thing on the engine test bench is a flickering prop, not to mention the FCNB-2000 project drawn on the drawing board.

Not to mention the cutting-edge aerodynamic technology on FCNB-2000, Tengfei Group has not fully mastered it, even if it is mastered, the whole project has entered the engineering implementation stage, and Tengfei Group has to stare at the drawings dryly, because domestic manufacturers can not make up the aircraft, even a common pivot in it can not be done.

There is no way, forging is required to process this kind of thing, 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 greater the strength of the forging equipment, the better.

The problem is that only a few domestic manufacturers have 100-ton multi-directional die forging equipment, and this level can process about 50-ton aircraft pivots at most, and the performance is not stable, and hundreds of tons of large aircraft at least need more than 5000 tons of multi-directional die forging equipment to process.

Such a large heavy equipment is completely blank in China, and now it is good, Zhuang Jianye is three points true, seven points false for a while, just one, now used for the production of Tu-204 passenger aircraft, in the early years of processing the Tu-160 strategic bomber variable sweep wing connection pivot of the Ural Heavy Machinery Plant original 18,000-ton multi-directional die forging hydraulic press to get over.

Not to mention Huang Feng and Fang Yong, it is just drooling that makes anyone in the aviation industry greedy.
