If Marcelo still has the intention of changing the topic in the previous sentence, then the latter words are really emotional, so that other people in the cockpit can detect the surprise and amazement in Marcelo's words.

I was stunned for a moment, and then I carefully felt the situation in the cabin, and it was indeed as Marcelo said, the noise in the cockpit was really not ordinary.

You must know that ordinary aircraft, especially small tonnage aircraft such as Y-6, due to the limitations of structure and materials, the noise control is not very good, and the huge engine roar completely runs through the voyage.

In fact, not to mention a small plane, this year is a large civil airliner, noise control is not very ideal, but due to the large volume, some sound insulation materials can be laid, which can make the noise not too strong, but even so, passengers close to the engine position, will still be told by the engine to run the roar and shock of the restless.

But in the cabin of the Y-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 bear child fluctuating the spring, although it can be heard, it will not make people irritated, and it will not hinder communication.

Even whispered words between each other can be easily heard by the other party, instead of being shouted out loudly like other similar aircraft to achieve the same purpose.

If nothing else, just listen to the two Chinese pilots in the front row and the ground contact, and the tone and tone of their voices are very peaceful, just like casual conversation in person, without any deliberate emphasis.

After the other people in the cockpit found out about this problem, they looked at each other and were a little dazed, especially the staff of the French and German embassies in China, with confused eyes and question marks in their heads.

What's wrong with the low sound? Isn't this normal? Isn't the noise of our airliners going back and forth between China and Europe like this, what's all the fuss.

In fact, not only the two embassy staff in China, but also Mekran, who is also a brother and sister, also looked at Marcelo with a questioning face, I don't know what this good friend who shares weal and woe means, why did he suddenly get into the noise, what can be different about the noise of the plane? Does it mean something? It seems that the noise in his private room is quite loud, but Marcelomo is not......

Somehow, a blush suddenly appeared on the young Merklene's face full of Germanic masculinity.

The two embassy staff in China were ignorant, and Marcelo didn't expect the two outsiders to understand anything, anyway, the purpose of changing the topic was reached, and then he said that he was tired and wanted to sleep for a while, and the matter was over.

But it's not good for the next Mekline to misunderstand, you must know that in the past three weeks, the two of them have supported each other and each other, and have already given birth to a different kind of relationship beyond friendship, for which the two have also made a domineering oath to God similar to the mountain without a tomb, and the unity of heaven and earth is to dare to be with the king.

This made Marcelo have to explain, so he patted Merklein's slightly rough hand lightly, and said with a smile: "You know, my dear Merklein, I used to study aeronautical engineering at the University of Paris, and later joined Dassault and Airbus as a technical engineer, and then because of interest, I left to AFP to become a foreign correspondent." ”

As he spoke, he pointed to the cabin next to him: "So I know some things on the plane very well, don't look at the noise of the cabin we are sitting in now is similar to that of our long-range large passenger planes to and from major cities in the world, but you must know that it is a large passenger plane with a take-off weight of hundreds of tons, and 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 not easy for small aircraft to do this, because their size is small, and the power of the engine is also small, if you increase the sound insulation materials and sound insulation equipment, it is bound to increase the total structure of the aircraft as a whole, thus affecting the basic performance of the aircraft. ”

Marcelo said very carefully, but Merkle was still a little dazed, but there was a lot of worship in his gray-blue eyes, Marcelo smiled very manly, and patted Merklein's hand again: "Just like the car you are familiar with, do you think the truck is easier to modify, or is the delicate Beetle sedan easy to add equipment?"

"Bigger trucks, of course. Merklein replied without thinking.

"It's the same with airplanes. Marcelo smiled and nodded, and then looked around the cabin: "So what surprised me is not that the noise is so small, but that I am surprised by what method this plane uses to achieve this effect, you must know that we are now flying over the Himalayas, with an average altitude of seven thousand meters, that is to say, this aircraft not only controls the noise to a very low level, but also must have strong warmth and pressurization properties, which are only available for large aircraft, but how big is this aircraft? It is estimated that the take-off weight is not more than 6 tons." ”

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

As soon as Marcelo's voice fell, a non-standard pronunciation of French came from the front row of him, which startled Marcelo, and just as he wanted to say something, he saw Gyanendra turn his head, make a silent gesture at Marcelo and Merklein, and then gesture to the side: "If you let people dream, it is not a polite act." ”

Marcelo turned his head to look and realized that the two embassy officials who had been babbling and asking them questions had fallen asleep on their seats at some point, and one of them was still snoring and drooling onto his clothes.

As a result, Marcelo had not yet recovered from the scene in front of him, when he heard Gyanendra continue: "Listening to what you just said, you should know a lot about airplanes, in that case, what do you think of this highland eagle?"

"Plateau Eagle, nice name!" Marcelo lowered his voice a little more, praised it, and then nodded very sincerely: " If it is really as you said, 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 very likely to be subversive, in addition to the noise and warmth I just mentioned, there are a total of 12 seats in the cabin, plus the main and co-pilots are 14, which means that the payload of this aircraft is almost 2 tons.

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

Speaking of this, Marcelo's dark gray eyes were full of incredulity, so much so that he had to stop and take a deep breath to soothe his spirits before he could speak again: "This means that the entire body structure is made very light, very strong, and very subversive, otherwise it will not reach such an indicator at all, at least there are no similar models I have seen in so many years." ”
