Previous page        Return to Catalog        Next page

    If there is anything Zhuang Jianye said that could make men fall silent and women shed tears, the "I Know Better" series of sentences definitely deserve the title.

    Regardless of anything else, as soon as Zhuang Jianye said these words, Song Changzheng directly raised his forehead, his head covered with black lines, not to mention Badia, Park Zhemin and others, who were completely stunned by these words.

    I thought to myself that this product came from nowhere. How dare you be so brazen and say that you know best about regional airliners?

    But while everyone in the cabin was stunned, Zhuang Jianye had already started his eloquent performance, the core of which was naturally the basic situation of the TRJ-500 regional passenger jet.

    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, with a maximum height of 1.92 meters, a maximum width of 2.63 meters, a floor area of ??46.3 square meters, and a total luggage compartment volume of 24.6 cubic meters.

    The empty weight of the aircraft is 17.5 tons, the fuel load is 8.7 tons, the maximum payload is 8.6 tons, the maximum take-off weight is 35 tons, and the standard seats are 64. The number of seats can be adjusted according to different needs, including 10 luxury business models and 24 seats.  There are four configurations: high-end business model; 44-seater simple model and 64-seater basic model.

    When necessary, the number of seats can be increased to 72 to perform full passenger transport tasks.

    The maximum ceiling is 13,200 meters, equipped with two wd-52ml turbofan engines, and the maximum speed is 860 kilometers per hour.

    With a cruising speed of 800 kilometers per hour, the maximum range when carrying 70 passengers is 3,400 kilometers on full fuel, and the range of the 10-seat luxury business model will reach 4,800 kilometers.

    Now, Zhuang Jianye is flying a 64-seat basic model of the TRJ-500 regional airliner. With full fuel, the range is 3,600 kilometers, which is enough to fly from Shanghai to the southern foot of the Qinling Mountains.

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

    Just when Zhuang Jianye was frothing and talking about the situation of the TRJ-500 regional passenger jet, Badia and Park Zhemin, who were sitting in front, suddenly had their eyes lit up. It seemed that they had caught the loophole they had been waiting for. The two immediately  After looking at each other, Park Zhemin immediately interrupted Zhuang Jianye's performance.

    Zhuang Jianye smiled when he heard this, and corrected Park Zhemin: "Sir, only the 10-seater luxury business model has a range of 4,800 kilometers, and ordinary passenger models can't reach this number."

    "Of course we know this." It was Badia who spoke this time, as aggressive as ever: "But how did we hear before that the T-500 radar warning aircraft, which was developed based on the TRJ-500 regional airliner, has a maximum range of more than  8,000 kilometers? I don¡¯t know if the previous data was wrong, or if Mr. Zhuang is telling the truth now?¡±

    Whether it is an error or the truth, the label of unreal data has been firmly pinned on Zhuang Jianye¡¯s head.

    Badia and Pu Zhemin¡¯s faces were full of curiosity, just like the good babies who revealed the emperor¡¯s new clothes. They acted like harmless humans and animals, but they were already happy in their hearts.

    They have been holding back for so long just waiting for a loophole on China's side. It doesn't matter how big or small it is, as long as it can be exploited. Anyway, what they want is to put pressure on them, so as to complete their grand plan.

    I thought that Zhuang Jianye, the head of Ascendas Group, should be more cautious than Song Changzheng. The two of them were still thinking about what to do. Unexpectedly, the other party made a mistake. The range of the civilian version and the military version are so different. This is okay. If  How can we understand it without breaking it down?

    So Badia and Park Zhemin seized the opportunity and ran away directly, saying that they would have to make Zhuang Jianye and Song Changzheng make concessions this time, either directly giving them the military version of Long Voyage, or contributing the civilian version to them for free, choose one of the two.  , they don¡¯t lose anything.

    Badia and Park Zhemin are shrewd, and counselors or representatives from other countries are not fools, otherwise they would not be able to sit in this position, so when Badia and Park Zhemin fired, others stood aside and said nothing, and some even expressed  De was filled with righteous indignation, obviously trying to give Badia and Park Cheol-min more momentum to rally and denounce Ascendas Group for discriminating against them if they disagreed.

    Seeing this, Song Changzheng in the seat couldn't help but feel a little worried. He was about to get up and help Zhuang Jianye smooth things over, but was stopped by Zhuang Jianye's look. He immediately glanced at the performance of everyone in the cabin with a smile, and finally fixed his gaze.  Regarding Badia and Park Zhemin: "The questions you raised are very good. Even if you don't talk about it, I will talk about it."

    As he spoke, he turned his head and directed towards the equipment cabin behind him and ordered: "Kid, bring the things here."

    As soon as he finished speaking, the assistant boy came over with a palm-sized triangular metal cube. Zhuang Jianye didn't take it, but raised his chin at Badia and Park Zhemin, signaling to give them the thing.

    Although Badiya and Park Zhemin felt strange, they were very happy in their hearts.They didn't take it seriously. Even if they took out the alien life, neither of them would cause any trouble, because those things were nothing compared to their Bai Lao plan, so they scorned Zhuang Jianye's actions, thinking that they would take advantage of it.  Just show them something and make them fall to the ground and bow their heads?

    Dream on!

    Just thinking about it in his heart, he still had to do some superficial work, so Park Zhemin pulled a face and took the cube from the child's hand seemingly seriously. At first, it was nothing, so he put it in his hand and played with it, but  The next moment, Park Zhemin's slender eyes suddenly widened, and the movements of his hands quickened rapidly. He immediately turned his head and looked at Badia aside, and uttered one word in surprise: "It's aluminum-lithium alloy!"

    Hearing this, Badia still waved his hands nonchalantly: "Hey~~ It's just aluminum-lithium alloy, what's the big deal"

    "It is not an ordinary aluminum-lithium alloy, but a third-generation aluminum-lithium alloy, a third-generation aluminum-lithium alloy that can be used in missile warhead casings, low-temperature fuel storage tanks, and projectile casings!"

    Park Zhemin lowered his voice with a shocked trembling voice. Although his voice was not loud, each word hit Badiya's heart like a heavy hammer, which surprised this Persian who has a high level of ambition.  , then shocked, and finally a look of shock.

    It¡¯s 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. Therefore, although this material is generally said to be advanced, it will not cause too many people¡¯s surprises.

    However, the third generation of aluminum-lithium alloys is different. The reason for this is very simple. Compared with the previous two generations, the third generation of aluminum-lithium alloys are lighter, stronger, and tougher. At the same time, their processing adaptability has also been improved.  Great improvements, especially in weldability, have allowed this lightweight metal material to completely get rid of the constraints of the riveting process and fully embrace the welding process, thereby further reducing the structural weight of the 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%, fundamentally increasing the range.

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