Chapter 1020

Although Lao Mu was born in the air force, he used to fly a strong-5 fighter in his early years. Later, with his promotion, he changed from a fighter air force to a helicopter air force.

In the 1980s, the army aviation force was set up. In order to cultivate special army aviation personnel, the helicopter flight academy affiliated to the air force at that time was renamed Army Aviation Academy.

At that time, Lao mu, who was the director of the teaching and research section, was transferred from the air force to the army. Because of this, Lao Mu cared so much about the helmet of the "sniper" pilot before.

Because it's a modern helmet specially made for helicopter troops, especially for armed helicopter troops. Coupled with the advanced cockpit layout inside zhi-12, Lao mu can't wait to get in and fly into the sky to see if he is happy.

As a result, everyone was attracted by the nb-2500v automatic wire laying machine. Who can make this thing known as aerospace hegemony? It is a legend to make the processing of carbon fiber composites efficient and simple.

Because of this, including the head of the headquarters, all feel that the automatic wire laying machine is a good thing representing the future, or even subverting the future.

In contrast, the "sniper" helmet, which has already been displayed, is naturally nothing new. Even if Lao Mu is very reluctant, he can't wring his arm but his thigh. After all, it's only ten years since the formation of the army aviation force. Among all the services and arms in the army, it's the youngest of the youngest, and the voice is naturally less powerful than that of the leaders of the old troops.

So looking at other people following to see the nb-2500v automatic wire laying machine, he is not good at it. He just hides at the back as usual, looking forward to the early end of the visit here, and seeing if he has the opportunity to apply for driving straight-12.

As a result, just after Lao Mou stood behind the crowd, wondering how to mention it to the head of the headquarters and how to fully implement it, Zhuang Jianye's sentence: "the hub of the bearingless helicopter" was like a heavy hammer, which directly made Lao Mou blush.

No way, it is "bearingless helicopter hub" this sentence to the old Mou to shock.

Although he is a professional in aviation, Lao mu, who is inclined to apply, is not as excited as Lao Wei, who is engaged in basic production, when he sees the nb-2500v automatic wire laying machine.

On the contrary, on the "hub of bearingless helicopter", Lao Wei is not as excited as Lao Mou Lai.

In particular, Lao Mou, who has been engaged in helicopter practice and theory for more than ten years, is a compound talent. When he hears this word, it's like a wonderful fairy music, and he can't help himself.

The reason is very simple, because "bearingless helicopter hub" is the most disruptive new technology in the field of rotorcraft.

How subversive is it?

Just look at the "Comanche" helicopter that the United States is testing.

If the B-2 bombers hang other types of bombers, and the F-22 rolls over all the fighters in the world, then Comanche's position in the helicopter field is the same as that of the B-2 and F-22 in their respective categories. They both hang and roll over.

In addition to the stealth capability of Comanche helicopter, the key is its subversive breakthrough in structural weight reduction and flight quality.

Even the American test pilot said to the media without exaggeration: "Comanche's driving experience is similar to that of a real fighter. It's very flexible and smooth. It can almost turn the actions in your mind into flying posture, so that you can do whatever you want at low altitude. Only by this, the world's similar helicopters may not achieve it in 20 years."

As soon as the American pilot's remarks came out, Europe and Russia, which are also regions and countries with strong helicopter production, became rich in lemon essence.

No matter whether the flying quality is good or bad, they dare to say that they will not be able to achieve the flying performance of "Comanche" in another 20 years. This is not an ordinary slap in the face, but a frenzy of pulling out their necks.

Europe and Russia may not be able to do stealth, but when it comes to the experience and accumulated flight performance, Europe and Russia are not afraid of anyone.

Because the flying performance of a helicopter is the same as that of a car. It doesn't mean that an engine and a gearbox can make the car silky smooth.

Is the chassis hard? What is the gear speed of the gearbox? How to achieve linear engine output, and how to burst it?

Such a variety of products can not be easily installed to produce explosive performance, but it needs the accumulation of automobile manufacturers over time to find a just right balance point through massive data comparison.

It's the same with helicopters. Turboshaft engines with main reducers and excellent flying quality depend on the matching and adjustment of the two key components. In this respect, Europe and Russia are no worse than the United States. The experience bar is also full. Why can't we upgrade the American people?

As a result, the disbelieving Europeans and Russians plunged into the pit of improving the helicopter's flying quality. After several years, they found that it was not their lack of experience, but the American. Instead of speaking of martial arts, he directly removed all the bearings on the hub, reducing the weight of the complex hub by nearly 50%.Such a lightweight hub breaks away from the shackles of the bearing, which is equivalent to a horse breaking away from the shackles. Naturally, the flight attitude can be changed according to the pilot's various ideas.

In this way, the Europeans and Russians have no incantation.

Because the hub of their helicopter is unable to cut off the bearing and complex hydraulic pull rod matrix, the helicopter direction adjustment is realized by the forward and backward left-right deflection of the propeller.

In order to control the deflection of the propeller, it is necessary to use complex bearings and hydraulic connecting rods to connect the hub with the control system to form a complex mechanical control structure.

It can be seen from the general helicopter that there are a row of hydraulic connecting rods under the hub. At the same time, the connection between the blade and the hub is equipped with bearings, and the hub and connecting rod also have bearings associated with each other.

Europeans and Russians have studied this complex mechanical structure thoroughly, but the Americans simply don't use it. It's just like a bad old man. He only looks at beautiful women for pleasure. Suddenly, one day, the old brother's reaction is huge, and he starts racing with beautiful women. This scene is not only the subversion of his ability, but also the subversion of his three outlooks.

So Balabala's empty wallet, with a sigh of helplessness and a thorough understanding, continued to nibble at his old capital slowly along the way of traditional complex mechanical paddle hub.

Some Europeans are not reconciled, and the economic dividend brought about by European integration has greatly increased European confidence. Other areas can not compete with the United States. Is it not enough for the helicopter that has the most experience?

So they began to increase investment. They wanted to compete with the United States on helicopters. As a result, they were slapped to the ground by the Americans before their wrists were exposed. There were no key materials, no core parameters, no production technology, no professional processing equipment, no anything, no wrists, no nonsense.

As a result, Tengfei group has such a new technology that even Europe and Russia can't come up with. How can Lao mu, a senior military officer engaged in land and aviation academic and teaching work, not be excited.

So he swallowed his saliva and asked Zhuang Jianye, "can I fly?"

Zhuang Jianye is not ambiguous, pointing out: "of course you can!"
