If Zhuang Jianye said anything that could make men silent and women cry, the "I know better" series of sentences is absolutely deserved.

Regardless of anything else, as soon as Zhuang Jianye's words came out, Song Changzheng directly supported his forehead, full of black lines, not to mention Badia and Park Zhemin and others, who were completely stunned by this sentence.

The heart said that this came out of nowhere, and he dared to be so ashamed to say that he knew the best about regional airliners?

But just as everyone in the cabin was stunned, Zhuang Jianye had already begun his gushing performance, and the core was naturally the basic situation of the TRJ-500 regional airliner.

The entire aircraft is 31.5 meters long, 7.3 meters high, 2.8 meters wide and has a wingspan of 23.2 meters.

The cabin is 19.7 meters long, 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 baggage compartment is 24.6 cubic meters.

The empty weight of the aircraft is 17.5 tons, the fuel load is 8.7 tons, the maximum load is 8.6 tons, the maximum take-off weight is 35 tons, and the standard seats are 64 seats, and the number of seats can be adjusted according to different needs, which are 10 seats luxury business type, 24 seats high configuration business type, 44 seats simple type, 64 seats basic type and other four configurations.

If necessary, the number of seats can be increased to 72 to carry out fully loaded passenger tasks.

The maximum ceiling is 13,200 meters, equipped with two WD-52ML turbofan engines, and the maximum speed is 860 km \h.

At a cruising speed of 800 km/h, the maximum range is 3,400 km with 70 passengers on full fuel, and 4,800 km for a 10-seater Business Class.

Today, Zhuang Jianye is riding the 64-seat basic version of the TRJ-500 regional airliner, with a range of 3,600 kilometers when fully fueled, which is enough to fly from Shanghai to the southern foot of the Qinling Mountains.

"Wait...... Mr. Zhuang, you just said that the TRJ-500 regional airliner has a maximum range of only 4,800 kilometers?

Just as Zhuang Jianye was foaming at the mouth and talking about the situation of the TRJ-500 regional airliner, Badia and Park Zhemin, who were sitting in front, suddenly lit up, as if they had caught the loophole they had been waiting for for a long time, and the two immediately looked at each other, and then Park Zhemin interrupted Zhuang Jianye's performance.

Zhuang Jianye smiled when he heard this, and corrected Park Zhemin: "This gentleman, a 10-seater luxury business class can have a range of 4,800 kilometers, and ordinary passenger models can not reach this number. ”

"Of course we know that. This time it was Badia who spoke, and his momentum was as aggressive as ever: "But how did we hear that the T-500 radar warning aircraft developed on the basis of the TRJ-500 regional airliner has a maximum range of more than 8,000 kilometers? I don't know if the previous data is wrong, or what Mr. Zhuang is saying now is the truth?"

Whether it is a mistake or the truth, a hat with untrue data is firmly buckled on Zhuang Jianye's head.

Badia and Park Zhemin's faces were full of curiosity, just like a good baby who exposed the emperor's new clothes, and the performance was harmless to a human being, but their hearts were already happy.

They have been holding back for so long to wait for the loopholes on the Chinese side, it doesn't matter how big or small, as long as they can use them, anyway, what they want is to exert pressure, so as to complete their big plan.

I thought that Zhuang Jianye, the head of the Tengfei Group, should be more cautious than Song Changzheng, and the two of them were still thinking about what to do, but they didn't expect the other party to make a mistake, the range difference between the civilian version and the military version is so big, this is okay, if you don't break it up, how can you do it?

So Badia and Park Zhemin seized the opportunity to run directly, saying that this time they would also let Zhuang Jianye and Song Changzheng make concessions, either directly to the military version of the long voyage, or to contribute the civilian version to let them be white, choose one of the two, they will not lose anything.

Badia and Park Zhemin are shrewd, and the counselors or representatives of other countries are not fools, otherwise it would be impossible to sit in this position, so when Badia and Park Zhemin opened fire, others watched from the sidelines, and some even showed righteous indignation, obviously giving Badia and Park Zhemin a strong momentum, and if they disagreed, they would join together to denounce the Tengfei Group for discriminating against them.

Seeing this, Song Changzheng in the seat couldn't help but be a little worried, and was just about to get up to help Zhuang Jianye round the field, but was stopped by Zhuang Jianye's eyes, and immediately glanced at the performance of everyone in the cabin with a smile, and finally fixed his eyes on Badia and Park Zhemin: "The two of you have asked very good questions, even if you don't say it, I have to talk about this matter." ”

As he spoke, he turned his head and commanded at the equipment cabin behind him, "Little boy, bring the things." ”

As soon as the words fell, the assistant Xiaotong came over with a palm-sized triangular metal cube, Zhuang Jianye did not answer, but raised his chin at Badia and Park Zhemin, signaling to give them something.

Although Badia and Park Zhemin felt strange, they were very disapprehensive in their hearts, even if they took out alien life, neither of them would make any waves, because those things were not worth mentioning compared to their big plans, so they were very sneering at Zhuang Jianye's actions, thinking that taking out something would make them throw themselves to the ground, and bow down?

Dream on!

It's just that I thought about it in my heart, and the surface work still had to be done, so Park Zhemin pulled a face, and took the cube from the child's hand with a seemingly serious attitude, at first it was nothing, and he played with it in his hand, but the next moment Park Zhemin's slender eyes suddenly widened, and the movements in his hands accelerated rapidly, and then he turned his head to look at Badia on the side, and spit out a word in surprise: "It's aluminum-lithium alloy!"

Badia waved his hand nonchalantly when he heard this: "Hey~~ Isn't it just aluminum-lithium alloy, what's the big deal......"

"It's not an ordinary aluminum-lithium alloy, but a third-generation aluminum-lithium alloy, a third-generation aluminum-lithium alloy that can be used in the shell of the missile warhead, the cryogenic fuel storage tank, and the shell of the missile body!"

With a shocked trill, Park Zhemin lowered his voice and said, although the voice was not loud, but every word was like a hammer in Badia's heart, so that this Persian with a high eye was surprised, then stunned, and finally shocked.

It is no wonder that the two of them are like this, aluminum-lithium alloy is a popular metal material in the aerospace field and is widely used, so it is generally said that although this material is advanced, it will not cause too many people's surprises.

However, the third generation of aluminum-lithium alloy is different, the reason for this is very simple, compared with the previous two generations of lighter weight, higher strength, greater toughness at the same time, the processing adaptability has also been greatly improved, especially in weldability has made great progress, so that this lightweight metal material completely free from the shackles of the riveting process, fully embrace the welding process, thereby further reducing the structural weight of aircraft or spacecraft.

Especially on missiles or launch vehicles, the third-generation aluminum-lithium alloy combined with welding technology can often reduce the weight of the original missile or launch vehicle by 12% to 30%, and fundamentally improve the range.

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