Of course, this is only the army unit, placed in the navy, the extra hundreds of kilograms of load is more precious, for example, you can choose a more powerful hoisting sonar, another example can be added multi-functional anti-submarine system, there is an optional magnetic detection system, no matter how poor it can be placed rescue hoisting equipment to carry out anti-submarine missions other than sea rescue missions, and so on.

It is no exaggeration to say that once the technology such as "bearingless helicopter propeller hub" is really implemented, it is enough to make the domestic helicopter level to a shocking corner overtaking, even if it cannot reach the world's first echelon, it will also emerge in the second echelon.

Thinking about the special helicopter customized by Tengfei Group for the Army Aviation Special Brigade more than a year ago that can avoid radar search, the head of the headquarters is still very confident in Zhuang Jianye's words.

But in spite of this, he still wanted Lao Mou to give it a try, first, Lao Mou is an expert in this field, engaged in the theoretical research and practical application of land aviation equipment for many years, and has rich experience; secondly, and most importantly, it is to feel what level the "bearingless helicopter propeller hub" of Tengfei Group is.

Don't come over to cheat funds just because you haven't learned a little bit from abroad.

Yes, what Zhuang Jianye wants to do, the head of the headquarters is naturally clear, it is nothing more than that he said that he is not bad for money, this stinky boy who got into the eye of money can't hold back, and hurriedly took the project to ask for funds.

Although the Asian financial crisis last year and the shortage of funds this year were also somewhat lacking, the state's support for the past year directly increased by 15.8 percent, and this is only the daily military expenditure of the troops; in contrast, the investment in scientific research increased by 22.7 percent, reaching the highest level in history.

Moreover, as the state has liberalized commercial housing and vigorously supported real estate, land prices have begun to rise beyond expectations, and units at all levels in charge of the armed forces, which are steadily withdrawing from commercial business activities, have also gained a lot during this period; in addition, substantial progress has been made in bilateral talks with the United States on joining the WTO, and it is expected that a bilateral agreement will be signed in the middle of next year, thus completing a decisive step toward WTO accession and benefiting the export market.

In addition, the country's fiscal reform has been successfully completed, and the central government's fiscal revenue has increased by a large margin, so that it can concentrate more efforts on doing major things.

With all these things combined, the troops who have endured for nearly 20 years can finally straighten their waists and roar arrogantly at the sky and the earth: "Lao Tzu is finally going to be rich." ”

However, there is money to be rich, but you can't spend it indiscriminately, as the so-called poor and poor way of living, rich and rich life, you can't always take a statistical report and original drawings to run over and ask for money to give generously, that is not a fool.

Therefore, Zhuang Jianye said that the head of the "bearingless helicopter propeller hub" headquarters should be seen, and it has to be experienced by professionals in person, no way, the "bearingless helicopter propeller hub" looks simple to the point of explosion, and it seems that children can save a top sample with rubber bands.

But in fact, the key to the "bearingless helicopter hub" is precisely the so-called "rubber band", that is, the carbon fiber composite flexible load-bearing beam located directly below the wheel hub, and the carbon fiber composite bundle wire that is glued to the blade and wound like a twist.

Although they are all carbon fiber composite materials, carbon fiber composite materials are very different from each other, just like stars and stars, there is always a top stream, two, three, four and five lines.

The same is true for carbon fiber composite materials, not to mention ordinary carbon fiber composite materials such as T300 and T500, even if it is an aerospace-grade T800 or even the M40J series.

Because the carbon fiber composite material of the helicopter propeller hub not only needs high strength, but also needs high toughness, otherwise when controlling the deflection of the propeller, what should I do if it clicks and breaks?

At the same time, the carbon fiber composite materials that meet the ultra-high strength and ultra-high toughness can only be made by the United States in the world, otherwise why did Europe and Russia climb out of the deep pit of the "bearingless helicopter paddle hub" not long after?

To put it bluntly, there is no comparable product comparable to the United States in terms of high-strength and high-toughness carbon reduction fiber composite materials, and because of this, even if Europe and Russia adjust the complex mechanical paddle hub to the extreme, they can only watch the back of the leading generation of Americans.

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

The roar of the helicopter roared again in the Huancheng optoelectronic production base of Tengfei Group, on which the pilot sat in the co-pilot's seat, and Lao Mou sat on the main pilot with the helmet of the "sniper" pilot, and was slowly hovering at a height of 40 meters above the ground, bringing a gust of wind.

Despite this, Zhuang Jianye still faced the strong wind and stuck to the head of the headquarters to introduce to him the situation of Tengfei Group's use of "bearingless helicopter propeller hubs" on the Z-12 in the sky.

"Our Tengfei Group has taken the same path as the Americans, and it is also through the pre-research of the next generation of combat aircraft and the accumulated technical achievements, which are applied to our helicopters. ”

"Oh? You mean that the Z-12 in the sky has applied the technological achievements of the 'killer' plan?" The head of the headquarters was a little surprised, he did not expect that the wheels of the helicopter would be related to the next generation of combat aircraft in the "killer" plan.

Zhuang Jianye nodded, and then asked with a smile: "Chief, you should still remember the H-ZB800 super-strength\high-toughness carbon fiber composite material, right?"

"Remember, and the No. 10 Chief Engineer, oh no, it should be called the No. 20 Chief Engineer now, he has circled 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, said slowly, and then stretched out his finger to the sky: "Don't tell me, the hub uses H-ZB800." ”

"The chief is the chief, nothing can be hidden from your eyes, the cross-shaped flexible beam under the hub is made of H-ZB800 super strength \ high toughness carbon fiber composite materials. ”

Saying that, he added mysteriously: "The processing equipment is the improved NB-2800X of NB-2500V, with a total weight of only 140 kilograms, and the titanium alloy parts of the same volume are half lighter." ”

The head of the headquarters glanced at Zhuang Jianye: "Don't give me a sycophant, you know that your kid still has good things to come up with, NB-2800X should be a professional aviation parts processing equipment, right?"

As he spoke, he tilted his neck and pointed to the helicopter in the sky with his chin: "The twist-shaped winding joint connecting the paddle hub and the blade is also made by the combination of H-ZB800 and NB-2800X." ”

"It's not!"

"Isn't it?" 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 bowed slightly, but the next moment his eyes gradually widened, he tilted his head sharply, and asked in surprise: "Your products have been upgraded again?"
