Chapter 1022

Of course, it's just the army. If you put it in the Navy, the extra load of several hundred kilograms will be more valuable. For example, you can choose a more powerful dipping sonar; for example, you can add a multi-functional antisubmarine system; for example, you can also install a magnetic detection system; if not, you can also install rescue lifting equipment to perform maritime rescue tasks other than antisubmarine tasks, and so on.

It is no exaggeration to say that once the "bearingless helicopter hub" and other technologies are really implemented, it will be enough to make the domestic helicopter level to overtake in a shocking curve. Even if it can not reach the world's first echelon, it will also emerge in the second echelon.

Think about a year ago, Tengfei group customized a special helicopter to avoid radar search for the land aviation special brigade. The head of the headquarters was very confident in Zhuang Jianye's words.

However, he still wanted Lao Mu to have a try in person. First, Lao Mu is an expert in this field. He has been engaged in theoretical research and practical application of land and aviation equipment for many years and has rich experience. Second, and most importantly, he wants to find out what level the "bearingless helicopter hub" of Tengfei group is.

Don't come here to cheat money after learning a little foreign knowledge.

Yes, the head of the headquarters knows exactly what Zhuang Jianye wants to do. It's just that he says he's not bad for money. The stinky boy who gets into the money hole can't hold on to it. He quickly takes the project as a treasure to ask for funds.

For serious things, the head of the headquarters is really not afraid to pay. Despite the Asian financial crisis last year and the shortage of funds this year, the country's support increased by 15.8% in the new year, which is just the daily military expenditure of the army. In contrast, the investment in scientific research increased by 22.7%, reaching the highest level in history.

Moreover, with the state liberalizing commercial housing and vigorously supporting real estate, land prices began to rise more than expected, and the units in charge at all levels who are steadily withdrawing from commercial activities have also gained a lot during this period. In addition, substantial progress has been made in bilateral negotiations with the United States on its accession to the WTO, and it is expected that a bilateral agreement will be signed in the middle of next year to complete the decision on its accession to the WTO The first step is to improve the export market.

As well as the successful completion of the country's financial reform and the substantial increase of the central government's fiscal revenue, we can concentrate more on major tasks.

Combined with all these things, the army, who has endured for nearly 20 years, can finally stand up straight and yell at the sky and the earth: "I'm going to be rich at last."

However, money belongs to money, but you can't spend it indiscriminately. As the saying goes, if you live in poverty, if you live in wealth, you can't get a statistical report and original drawings to come over and ask for money, then you can't be a fool.

Therefore, the head of the headquarters of the "bearingless helicopter hub" mentioned by Zhuang Jianye needs to see it, and it has to be experienced by professionals themselves. There is no way. The principle of the "bearingless helicopter hub" is so simple as to explode. It seems that children can save a very good sample with a rubber band.

But in fact, the key of "bearingless helicopter hub" lies in the so-called "rubber band", that is, the carbon fiber composite flexible load-bearing beam directly below the hub; and the carbon fiber composite bundle that is glued to the blade and twisted like a twist.

Although they are all carbon fiber composite materials, there is a big surprise between carbon fiber composite materials. Just like stars and stars, there is always a top flow, two three four five line difference.

The same is true for carbon fiber composites, not to mention ordinary carbon fiber composites such as T300 and t500, even the aerospace grade T800 or even M40J series.

Because the carbon fiber composite material of the helicopter hub needs not only high strength, but also high toughness. Otherwise, when controlling the deflection of the blade, what can we do if it breaks? Watching planes crash and people die?

At present, only the United States can make carbon fiber composites that meet the requirements of both ultra-high strength and ultra-high toughness. Otherwise, why did Europe and Russia plunge into the deep pit of "bearingless helicopter hub" and climb out of it soon?

That is to say, in terms of carbon fiber composite materials with high strength and high toughness, we can't get the same kind of products as the United States. Because of this, even if Europe and Russia adjust the complex mechanical hub to the extreme, we can only watch the United States lead the generation.

"Americans have conquered carbon fiber composite materials with high strength and toughness when developing a series of advanced stealth aircraft such as F-117, B-2 and F-22. For example, the skin used on F-22 airframe is made of this material..."

The roar of the helicopter once again roared in the Huancheng optoelectronic production base of Tengfei group. The pilot sat in the co pilot's seat, and Lao mu with the "sniper" pilot's helmet sat in the main pilot's seat. He was hovering slowly 40 meters above the ground, bringing a gust of wind.

Despite this, Zhuang Jianye still faced the strong wind and pasted in front of the head of the headquarters to introduce to him the situation that Tengfei group adopted the "bearingless helicopter hub" on the zhi-12 in the sky.

"Our Tengfei group is going the same way as the Americans. It is also through the pre research of the next generation of combat aircraft that the accumulated technical achievements are applied to our helicopters.""Oh? Do you mean that zhi-12 in the sky has applied the technological achievements of the killer's mace project? " The head of the headquarters was a little surprised. He did not expect that the hub of the helicopter would be related to the next generation of combat aircraft in the "Assassin's mace" plan.

Zhuang Jianye nodded, then asked with a smile: "chief, you should still remember the h-zb800 super strength and high toughness carbon fiber composite?"

"Remember, and chief engineer No. 10, oh no, should be chief engineer No. 20 now. He has delineated the h-zb800 as the main material for the skin and some structural parts of the next generation fighter." The head of the headquarters tilted his head, did not pass the wind, slowly said, immediately extended his finger to the sky: "you don't tell me, the wheel hub is h-zb800."

"The chief is the chief. You can't hide anything from me. The cross shaped flexible beam under the wheel hub is made of h-zb800 super strength and high toughness carbon fiber composite."

Then he added mysteriously, "the processing equipment is nb-2800x, an improved nb-2500v, with a total weight of no more than 140 kg. The titanium alloy parts of the same volume are half as light."

The head of the headquarters glanced at Zhuang Jianye: "don't flatter me, you will know that you still have something good to offer. Nb-2800x should be a professional aviation parts processing equipment, right?"

Then he raised his neck and pointed to the helicopter in the sky with his chin: "the twist like winding joint connecting the hub and blade is also made by the combination of h-zb800 and nb-2800x."

"No!"

"No?" The head of the headquarters frowned: "what's that?"

"It's a combination of h-zb1000 and nb-3200u!"

"H-zb1000 and nb-3200u..." The head of the headquarters nodded slightly, but at the next moment his eyes gradually widened and he turned his head fiercely. He was surprised and asked, "your products have been upgraded again?"
