Chapter 440 Very light, very strong, very subversive

Previous page        Return to Catalog        Next page

    If Marcelo had the intention to change the subject in the first sentence, then the next words were really out of emotion, so much so that other people in the cockpit could detect it. Marcelo's words were filled with surprise and amazement.  Emotions.

    ¡°Everyone was stunned for a moment, and then took a closer look at the situation in the cabin. Indeed, as Marcelo said, the noise in the cabin was really not that small.

    You must know that ordinary aircraft, especially small-tonnage aircraft such as the Y-6, do not control noise very well due to limitations in structure and materials. The roar of the huge engine runs throughout the entire flight.

    In fact, let alone small aircraft, these are large civil aviation aircrafts, and the noise control is not very ideal. However, due to the large size, some sound insulation materials can be laid, so that the noise will not be too strong. But even so,  Passengers who are close to the engine will still be disturbed by the roar caused by the engine running.

    But in the cabin of the Yun 6, the sound from the engine is not absent, but it is controlled within a small range, just like the sound of the neighbor's naughty child's swing spring. Although it can be heard, it is not annoying.  , and will not hinder communication.

    Even whispers between each other can be easily heard by the other party, unlike other similar aircraft that need to be shouted loudly to achieve the same purpose.

    Without saying anything else, you can hear the two Chinese pilots in the front row communicating with the ground. Their tone and tone are very calm, just like chatting in person, without any deliberate emphasis.

    After other people in the cockpit discovered this problem, they looked at each other and were a little confused, especially the staff of the French and German embassies in China, whose eyes were full of confusion and with question marks on their foreheads.

    What's wrong with the low voice?  Isn't this normal?  Our passenger planes traveling between China and Europe are not all so noisy, so what¡¯s the fuss?

    In fact, not only the two staff members of the embassy in China, but also Merchant, who was also a fellow sufferer, looked at Marcelo with doubts on his face. He didn't know what this good friend who had shared weal and woe meant, and why he suddenly got involved.  The noise has gone up. How can the noise of airplanes be different?  Does it mean something?  It seems that the noise in the private room is quite loud, maybe Marcelo

    ?????????????????????????? For some reason, a blush suddenly appeared on the young Merkelian¡¯s face, which was full of Germanic masculinity.

    It¡¯s okay that the two embassy staff in China were ignorant. Marcelo didn¡¯t expect the two outsiders to understand anything. Anyway, the purpose of changing the subject was achieved. Afterwards, he said that he was tired and wanted to sleep for a while, and the matter was changed.  .

    But it would be bad if Merklein next to him misunderstood. You must know that in the past three weeks, the two of them have supported and supported each other, and they have already developed a different kind of relationship that goes beyond friendship. For this reason, the two of them have even sent a message to God.  Similar to the mountain without mausoleum, the harmony of heaven and earth is a domineering oath that dares to be with the king.

    This forced Marcelo to explain, so he patted Merklein's slightly rough hand and said with a smile: "You know, my dear Merklein, I once studied at the University of Paris.  I majored in aviation engineering, and later worked as a technical engineer at Dassault and Airbus. Later, because of my interest, I left my job and went to Agence France-Presse to become a foreign correspondent."

    As he said that, he pointed to the cabin next to him: "So I know a lot about some things on the plane. Even though the cabin we are sitting in now has almost the same noise as the long-distance large passenger planes we travel to and from major cities in the world, you have to know  , it is a large passenger aircraft with a take-off weight of hundreds of tons. The huge platform means that there is great potential for modification, and there are more sound insulation materials and equipment that can be added.

    It is very difficult for small aircraft to do this, because they are small in size and have low engine power. If you add sound insulation materials and equipment, you will inevitably need to increase the overall structure of the aircraft, thus affecting the basic performance of the aircraft.  .  "

    Marcelo spoke very carefully, but Merkle was still a little confused, but there was a lot more admiration in his gray-blue eyes. Marcelo smiled manly and patted Merkle again.  Ryan's hand: "Just like the cars you are familiar with, do you think a truck is easier to modify, or a compact Beetle sedan that is easier to add equipment?"

    ¡°Of course it¡¯s a bigger truck.¡± Merklein answered without thinking.

    "The same goes for airplanes." Marcelo smiled and nodded, then looked around the cabin: "So what I'm surprised about is not that the noise is so small, but I'm surprised by what method this airplane uses to achieve this effect. You have to know that we  It is currently flying over the Himalayas, with an average altitude of seven thousand meters. This means that this aircraft not only controls the noise to an extremely low level, but also must have strong thermal insulation and pressurization properties. These are conditions that only large aircraft can meet.  But thisHow big does a plane need to be?  It is estimated that the take-off weight will not exceed 6 tons.  "

    "The maximum take-off weight is 4.8 tons."

    As soon as Marcelo finished speaking, a French sentence with an irregular pronunciation came from the stool in front of him, which startled Marcelo. Just as he was about to say something, Gyanendra turned his head and pointed at Marcelo and Mo.  Klein made a gesture to silence him, and then gestured to the side: "It is not polite to spare someone from sleeping."

    Marcelo turned his head and saw that the two embassy officials who had been asking them questions had fallen asleep on their seats at some point. One of them was snoring and drooling on his clothes.  .

    As a result, before Marcelo could recover from the scene in front of him, he heard Gyanendra continue: "From what you just said, you should know a lot about airplanes. In that case, what do you think of this Highland Eagle?"

    "Plateau Eagle? A good name!" Marcelo lowered his voice a little lower, praised, and then nodded sincerely: "If it is true, as you said, that the maximum take-off weight of this aircraft is 4.8 tons,  I think it is a very good aircraft, because the materials and production processes used in this aircraft are likely to be disruptive. In addition to the noise and warmth I just mentioned, there are a total of twelve seats in the cabin.  Including the pilot and co-pilot, there are fourteen, which means the payload of this aircraft is almost 2 tons.

    You came from the Tibetan capital, picked us up and returned to the Tibetan capital without supplies, a round trip of nearly 2,000 kilometers, so the maximum range of this aircraft must be more than 2,000 kilometers.  "

    At this point, Marcelo's dark gray eyes were filled with disbelief, so much so that he had to stop and take a deep breath to calm down before he could speak again: "This means that the entire body structure is made very light.  , very strong, very subversive, otherwise it would not be able to achieve such an indicator, at least the similar models I have seen over the years are not so good."
