Chapter 632 ZB-MAX Helicopter

Previous page        Return to Catalog        Next page

    Although Li Jiang complains about the model he drives, if others say so, this guy will spit it out in your face as soon as he turns around. Typically, only state officials are allowed to set fires, but ordinary people are not allowed to light lamps.

    This is also an inquiry from ground air traffic control. If it were anyone else, Li Jiang would have scolded his mother a long time ago. He dared to say that there was something wrong with this helicopter without even flying it. It was like playing the piano randomly.

    But even so, Li Jiang's tone to the ground air traffic control just now was not polite, but it didn't matter. Since he dared to fly this unique helicopter over Xingzhou, he had naturally made complete preparations. Otherwise, even if he  Agree, the domestic aircraft management department does not allow it.

    After all, if an aircraft falls from the sky, it can easily cause secondary accidents, especially in cities. If it kills or injures other people, the situation will be serious.

    Because of this, after receiving the request from Ascendas Group, the Civil Aviation Administration of China and the relevant departments of the Air Force formed a joint expert team to go to GE Aviation, a subsidiary of Ascendas Group, and conducted a comprehensive technical assessment and safety measurement of several aircraft models equipped by it.  Only then did they cautiously agree that Ascendas General Aviation aircraft can fly within Sin Chew City.

    In other words, the helicopter driven by Li Jiang didn't just break in rashly, it had approval documents on it.

    ¡­¡­

    "You said that the Civil Aviation Administration of China and the relevant departments of the Air Force have conducted assessments and there are no problems?"

    Just when Li Jiang was constantly looking for shooting angles according to Ju Tao's request, in the compound of the families of Xingzhou cadres, the leader who asked the staff to find out how the scary helicopter appeared in the sky over Xingzhou also  After receiving the reply, he couldn't help but frown, wondering why he didn't know about this.

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

    "Yeah?"

    After hearing this, the local leader of Xingzhou frowned, obviously he did not remember.

    "It is indeed true. I have some impressions. We even mentioned it in the team meeting at that time. However, firstly, our main focus is on Yonghong Factory. Secondly, experts from the Civil Aviation Administration of China are involved in aviation matters.  We don't need to worry about the measurement, so we hurriedly uncovered it."

    At this time, another leader from Xingzhou finally remembered. After hearing this, the leader who had just been asked about it recalled it in a confused way.

    This is not what the comrade in charge of the team in front of me said. Not to mention last week, in the past six months, their local leadership team in Sin Chew has done nothing but been busy with the affairs of Yonghong Factory, so that  Other things were listed as secondary, and as long as there were no major problems, I could get over it.

    The same is true for the technical and safety assessment report submitted by the Civil Aviation Administration of China for Ascendas General Aviation's various aircraft types flying over the Xingzhou City area. Because aviation technical experts have the backing, local leaders like them did not take a close look at it. Of course, even if they did, it would not be possible.  I can¡¯t understand it, because this report has more than 2,000 pages, and more than 80% of it is filled with dizzying technical terms and precise icons.

    Because of this, even if things like Yonghong Factory were not involved, they, the management cadres engaged in local governance, would not cause any obstacles in this regard.

    It¡¯s just

    "We approved it, but who knew that this kind of thing would be flown by Ascendas Airlines? Look at it. If the two propellers rotate side by side, are you not afraid of being really twisted together?"

    Although the leader who asked the question knew that the plane in the sky was approved, he still questioned it with dissatisfaction. After hearing this, the leader who reminded him didn't know what to say and looked at the plane in the sky spinning left and right in the sky.  Helicopter, who didn't know what he was doing, also frowned. He was about to say something innocuous to express the consistency of their leadership team.

    But before he could speak, Yoder, who was staring at the sky in front of him, suddenly slapped his head with his hand, and immediately shouted excitedly: "I know, Gu, it's Kaman, the American Kaman, double rotor."  The two propellers are arranged horizontally crosswise and arranged in a V-shape. By optimizing the gears in the transmission structure, the two propellers can run in parallel. The K-600 general-purpose helicopter equipped in the United States in the 1950s has this structure. Oh my God,  I didn¡¯t expect you to introduce American technology.¡±

    " Coming to this conclusion, Yodel was fine on the surface, but he was very shocked in his heart. Only the American Kaman Aerospace Company in the world is persistently researching this kind of dual-rotor horizontally crossed 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 others, take the K-600 general-purpose helicopter equipped by the US military in the 1950s.It is only 1.8 tons in the air, but its maximum take-off weight is 3 tons.

    Its carrying capacity reaches 1.2 tons. Although the number is not large, this weight is close to 70% of the weight of the aircraft itself.

    Items that can carry 70% of their own weight. As far as this data is concerned, it is difficult for even today's aircraft to achieve it. However, the K-600 general-purpose helicopter with a double-rotor transverse cross-arrangement has already done this in the 1950s.  Knowing that there were no composite materials, no CNC machine tools, and no other advanced manufacturing technologies at that time, why?

    Not only does it seem weird, but the clever layout makes everything impossible possible.

    Because the twin propellers in this layout counter-rotate to offset the reverse unbalanced force, the tail rotor and complex transmission device can be removed, so the entire speed reducer can be made lighter and more compact, and the internal mechanism is also greatly simplified.  , coupled with other optimizations, the entire helicopter can be made compact and lightweight, which creates a large proportion of the carrying capacity of this type of aircraft.

    What Yoder didn't expect was that this kind of unique technology in helicopter weight reduction would be transferred to China by the Americans. This made Yoder feel envious and jealous, and he kept wailing in his heart. Kaman Company  Damn it, why don¡¯t you transfer it to our Leipzig company in Germany!

    " Equally shocked was the local leader in Sin Chew who kept questioning. One moment he was asking whether the two propellers of the plane above would get mixed together and fall down, and the next second he asked the translator to find out what Yoder said.

    Suddenly, the entire Xingzhou local leadership team was dumbfounded.

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

    ???????????????? Why is this aircraft so different? It turns out that it is American technology, so there is no problem. The United States dares to say that it is number one in the world, who dares to say that it is second?

    " If not, the two propellers would have probably fought long ago. Since it is American technology, don't worry. It seems that Tengfei General Navigation is still very good. It is awesome to be able to use American technology.

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

    Gu Jingyou looked at Yodel who looked a little sad next to him, then turned his head and looked at the Xingzhou leaders who praised American technology, raised his eyebrows, and finally fixed his eyes on Yodel, and said with a strange expression: "  American technology? Mr. Yoder, is your conclusion too superficial? The ZB-MAX helicopter in the sky is all self-developed products of our Ascendas Group. If any of the core components except avionics are American, I will  Gu Jingyou takes off his head and lets you kick it like a ball."
