Take Off My Aviation Era

Although Li Jiang complained about the models he was driving, if others said that, this guy could spray you on the face when he turned his face. Typically, only state officials are allowed to set fires and the people are not allowed to light up lights.

This is also the question of the ground air traffic control. When I was someone else, Li Jiang would have been scolding his mother a long time ago. He hadn't even driven the helicopter before, so he dared to say that there was a problem with this thing, and he was playing the piano.

But even so, Li Jiang’s tone of air traffic control on the ground just now wasn’t considered polite, but it didn’t matter. Since he dared to drive this alternative helicopter to appear over the sky over Sinzhou, he naturally made perfect preparations. Yes, the domestic aircraft management department is not allowed.

After all, if an aircraft falls from the sky, it is very easy to cause secondary accidents, especially in cities. The nature of the matter in case of death or injury to other people is great.

Because of this, after receiving the request of the Ascendas Group, the Civil Aviation and the relevant departments of the Air Force formed a joint expert group to the General Aviation Group under the Ascendas Group to conduct a comprehensive technical evaluation and safety measurement of several aircraft types. Only then prudently agreed that Ascendas General Aviation's models could fly in Sin Chew City.

In other words, the helicopter piloted by Li Jiang didn't rush in rashly. People had written approval.

...

"You said that the Civil Aviation Administration and the relevant departments of the Air Force have done an assessment, there is no problem?"

Just as Li Jiang was looking for the shooting angle according to Ju Tao's request, the leader who asked the staff to inquire about how the terrifying helicopter appeared in the sky above Sinzhou in the compound of the family members of the officials in Xingzhou When he got the reply, his brows couldn't help but frowned, and he asked why he didn't know about it.

At this time, the reporting staff replied: "There were indeed several evaluation reports transferred from the Civil Aviation Administration of Civil Aviation last week for you to read."

"is it?"

Hearing this, the local leader of Xingzhou frowned, obviously he didn't remember.

"This is indeed the case. I have some impressions. At the time we were still talking about it at the team meeting. But first, we focused on the Yonghong factory. Secondly, there are experts from the Civil Aviation Administration of China in aviation. We don’t need to worry about weighing, so we hurriedly expose it."

At this time, another leader of the Sinzhou area finally remembered. After listening to this, the leader who was inquiring about just now remembered it ignorantly.

It’s not the same as the comrades in front of the team, let alone last week, but in the past six months, their local leadership team in Sinzhou hasn’t done anything, so they have been busy working around the Yonghong factory. All other things are classified as secondary, as long as there is nothing serious about it, it will be over.

The same applies to the technical and safety assessment reports submitted by the General Administration of Civil Aviation of Ascendas General Aviation’s various types of aircraft flying over the urban area of ​​Sinzhou. Because there are aviation technical experts, their local leaders didn’t take a close look. Of course, even if you take a closer look. I can't understand it, because the report has more than two thousand pages, and more than 80% are dizzying technical terms and precise icons.

Because of this, even if there is no such thing as the Yonghong factory, these management cadres who are engaged in local governance will not cause any trouble in this regard.

only……

"We approved it, but who knows that Ascendas Airways is flying over this kind of thing, you see, the two propellers are rotating side by side, you are not afraid of being really twisted together?"

Although the leader who inquired knew that the plane in the sky was approved, he still questioned with dissatisfaction. After hearing this, the leader who reminded him didn't know when to say it. He looked at the plane in the sky and circled left and right. Circle, the helicopter who didn't know what it was doing frowned, and was just about to say something easy to say, to express the consistency of their leadership team.

But before he could speak, he saw Yodel, who was staring at the sky in front of him, suddenly slapped his head with a slap, and immediately shouted excitedly: "I see, Gu, it’s Kaman, American Kaman, twin rotors. The two propellers are arranged horizontally and crosswise, and the two propellers are arranged in a V-shape. Some optimization of the gears in the transmission structure can make the two propellers go in parallel. The K-600 general-purpose helicopters equipped in the 1950s have this structure. Unexpectedly, you introduced American technology."

Coming to this conclusion, there was nothing on Yodel's face, but he was very shocked. In the world, only the Kaman Aerospace Corporation of the United States has been researching this kind of double-rotor cross-arranged helicopter.

The reason for this is very simple, that is, this type of layout can greatly simplify the complex transmission mechanism of the helicopter, reduce the weight of the fuselage, and thereby increase the carrying capacity of the helicopter.

Regardless of other things, take the K-600 general-purpose helicopter that was equipped by the US military in the 1950s as an example. The airborne is only 1.8 tons, but the maximum take-off weight is 3 tons.

Its carrying capacity reached 1.2 tons, even though the figure is not big, but this weight is close to 70% of the weight of the aircraft itself.

It can carry 70% of its own weight. This data alone is difficult to achieve even with current aircraft. The k-600 general-purpose helicopter with two-rotor transverse cross-arrangement has been built in the 1950s. Knowing that there were no composite materials, no CNC machine tools and other advanced manufacturing technologies, why?

It doesn't look weird, but the clever layout makes everything impossible possible.

Because the reverse rotation of the double propellers of this layout offsets the reverse unbalanced force, the tail rotor and complicated transmission can be removed, so the entire speed reducer can be made lighter and smaller, and the internal mechanism is also greatly simplified. , Coupled with other aspects of optimization, the entire helicopter can be made compact and light, so as to create a large proportion of the carrying capacity of this type of aircraft.

It’s just that Yordel did not expect that this type of technology, which is unique in weight reduction in helicopters, was actually transferred to China by the Americans. This made Yordel both envious and jealous, wailing in his heart, Kaman Corporation. Damn you, why not transfer it to Leipzig, Germany!

Also shocked is any local leader of Sinzhou who is constantly questioning. A moment ago, he said whether the two propellers of the above plane would be tangled together and fall down~www.wuxiaspot.com~ I will send it to the translator in the next second. What Del said.

Suddenly, one of the entire local leadership team in Xingzhou was stunned.

what's the situation? Kaman Company? American technology?

Let’s just say why this aircraft is so different. It turned out to be American technology. Then it’s okay. The United States dares to say first in the world, but who dares to say second?

If not, the two propellers might have been fighting long ago. Since it is American technology, you can rest assured. It seems that Tengfei General Aviation is still very good, and it can bring American technology back.

So some words about how advanced the United States is, how awesome it is, spread among several leaders.

Gu Jingyou looked at Yordel, who was a little bit hurt next to him, and then turned his head to look at the leaders of Sinzhou who praised American technology. He raised his brows, and finally fixed his gaze on Yordel, and said with a weird expression: " American technology? Mr. Yordel, is your conclusion too superficial? The zb-max helicopters in the sky are all self-developed products of our Ascendas Group. Except for avionics, if any core parts are American, I Gu Jingyou took off his head and let you play as a ball."
