Chapter 839

If there is anything Zhuang Jianye can say that can make men listen to silence, women listen to tears, "I understand more" series sentence is absolutely worthy.

Whatever else, as soon as Zhuang Jianye's words were uttered, song Changzheng directly supported his forehead and covered his head with black lines. As for Badia and park Zhemin, let alone others, they were completely stunned by these words.

How dare you say that you know the regional airliner best?

However, Zhuang Jianye has already begun his endless performance, the core of which is naturally the basic situation of trj-500 regional airliner.

The whole aircraft is 31.5m long, 7.3m high, 2.8m wide and 23.2m wingspan.

The length of the cabin is 19.7 meters, the maximum height is 1.92 meters, the maximum width is 2.63 meters, the floor area is 46.3 square meters, and the total volume of the luggage compartment is 24.6 cubic meters.

The aircraft has an empty weight of 17.5 tons, a fuel load of 8.7 tons, a maximum commercial load of 8.6 tons, a maximum take-off weight of 35 tons, and 64 standard seats. The number of seats can be adjusted according to different needs, including 10 seat luxury business type, 24 seat high configuration business type, 44 seat simple type and 64 seat basic type.

If necessary, the number of seats can be increased to 72, so as to carry out the full passenger task.

The maximum lift is 13200m, equipped with two wd-52ml turbofan engines, and the maximum speed is 860kmh.

At a cruising speed of 800 kmh, the maximum range is 3400 km with 70 passengers on full fuel, and 4800 km for a 10 seat luxury business model.

Now, the 64 seat basic trj-500 regional airliner that Zhuang Jianye is riding is full of fuel, with a range of 3600 km, which is enough to fly from Shanghai stock market to the southern foot of Qinling Mountains.

"Wait Mr. Zhuang, you just said that the maximum range of trj-500 regional airliner is only 4800 km? "

Just as Zhuang Jianye was talking about the trj-500 regional airliner, Badia and park Zhemin, who were sitting in front of him, suddenly caught a glimpse of the loophole they had been waiting for. They immediately looked at each other, and immediately Park Zhemin interrupted Zhuang Jianye's performance.

Zhuang Jianye smiles and corrects to park Zhemin: "this gentleman, only a 10 seat luxury business model can have a voyage of 4800 kilometers, which is not available for ordinary passenger transport models."

"Of course we know that." This time, Badia opened his mouth and was as aggressive as ever: "but how did we hear that the T-500 radar warning aircraft based on trj-500 regional airliner has a maximum range of more than 8000 km? I don't know if the previous data is wrong, or Mr. Zhuang is telling the truth now? "

Whether it's wrong or the truth, a hat of untrue data is firmly on Zhuang Jianye's head.

Badia and park Zhemin's face is full of thirst for knowledge, just like a good baby who exposes the emperor's new clothes. They show that they are harmless to people and animals, but they are already happy.

They have been waiting for the loopholes on the Chinese side for so long. It doesn't matter whether they are big or small, as long as they can take advantage of them. Anyway, what they want is to put pressure on them to complete their big plan.

I thought that Zhuang Jianye, the leader of the take-off group, should be more cautious than song Changzheng. They were still thinking about what to do, but they didn't expect that the other party made a mistake. The civil version and the military version had such a big difference in their voyage. It's OK. If they don't understand, what can they do?

So Badia and Pu Zhemin seized the opportunity to run directly, saying that they would let Zhuang Jianye and song Changzheng give in this time, either directly give the military version of the long voyage, or contribute the civilian version to let them choose one from the other, and they would not lose anything.

Badia and park Zhemin are smart, and the counsellors or representatives of other countries are not stupid. Otherwise, they would not be able to sit in this position. So when Badia and park Zhemin fired their guns, other people stood on the sidelines and did not say anything. Some people even showed righteous indignation. It is obvious that they are giving Badia and park Zhemin a strong voice. If they have a big disagreement, they join together to denounce the difference between Tengfei group Depending on their posture.

Seeing this, song Changzheng on the seat was a little worried. He just got up to help Zhuang Jianye round the field, but he was stopped by Zhuang Jianye's eyes. He immediately smiles and sweeps his eyes at the performance of the people in the cabin. Finally, he fixed his eyes on Badia and park Zhemin: "your questions are very good. Even if you don't say them, I'll talk about them "Things."

Then he turned his head to the equipment cabin behind him and said, "little boy, bring the things here."

As soon as the words were heard, the assistant boy came over with a triangular metal cube the size of a palm. Instead of answering, Zhuang Jianye raised his chin to Badia and park Zhemin, indicating to give them something.

Badia and park Zhemin are surprised, but they don't think much of it. Even if they take out extraterrestrial life, they won't have any trouble, because those things are not worth mentioning at all compared with their big plan. So they sneer at Zhuang Jianye's action. They think that they can take out something to make them fall in love with each other and bow to them?Dream!

But in his mind, the superficial Kung Fu still needs to be done, so Park Zhemin took the cube in his hand with a face. At first, it was nothing, and he played with it in his hand. But at the next moment, park Zhemin's slender eyes suddenly widened, and his hand's movement speeded up. He immediately turned his head to look at Badia and vomited out in surprise One word: "it's aluminum lithium alloy!"

Badia smelled that Yan still waved his hand indifferently: "Hey ~ ~ it's aluminum lithium alloy. What's the big deal..."

"It's not a general Al Li alloy, but a third-generation Al Li alloy that can be used in missile warhead shell, cryogenic fuel storage tank and shell!"

With a tremor of shock, park Zhemin lowered his voice and said that although the voice was not big, each word was like a heavy hammer in Badia's heart, which surprised a Persian with eyes above the top. Then he was shocked, and finally his face was shocked.

No wonder they are like this. Aluminum lithium alloy is a popular metal material in the aerospace field, which is widely used. Generally speaking, although this material is advanced, it will not cause too many people's accidents.

However, the third generation of Al Li alloy is different. The reason is very simple. Compared with the previous two generations, the third generation of Al Li alloy has lighter weight, higher strength and greater toughness. At the same time, the processing adaptability has been greatly improved, especially the weldability has made great progress. This light metal material completely gets rid of the shackles of riveting process and embraces the welding industry So as to further reduce the structural weight of aircraft or spacecraft.

Especially in missiles or launch vehicles, the third generation of aluminum lithium alloy with welding process can reduce the weight of the original missiles or launch vehicles by 12% to 30%, fundamentally improving the range.

It is no exaggeration to say that it is the biggest technological breakthrough of metal materials in the aerospace field in the past 15 years.
