    "this¡­¡­"

    Zhuang Jianye was just about to answer when he felt the aroma of wine overflowing from the tip of his nose. When he looked again, well, the wine bottle in Ju Tao's hand was still pouring into the quilt, and it was all overflowing, and he didn't notice it.

    Seeing Zhuang Jianye's strange expression, Ju Tao immediately noticed that his bottle had not been taken back. He quickly took it down with an ouch, smiled sheepishly, and then said confidently: "I heard you said there is a way, I'm happy.  Yes, haha, by the way, Mr. Zhuang, I heard from the old man at home that the factory is planning to build its own aircraft, and it won¡¯t be this new model, right?¡±

    "Hi~~ You guys are quite well informed. Yes, it's this new model." Zhuang Jianye didn't hide it either. Tengfei Factory has been modifying the Y-5 for some time, especially after the wing removal from Yonghong Factory  After the introduction of ice and landing gear technology, the progress of modification has been rapid.

    Now the first prototype has been assembled. After a series of basic performance tests, it will be sent to the test bench affiliated to Xihang University for a series of body fatigue tests. If everything goes well, it will be completed before the end of the year.  A series of tests and then the first flight.

    Seeing Zhuang Jianye nodding in recognition, Ju Tao's fat face immediately turned into a chrysanthemum smile, and he quickly asked: "How high can you fly?"

    "The design ceiling is 7320 meters."

    "7320 meters" Ju Tao pondered for a moment, then nodded: "Although it has not reached the height of Mount Everest, the height of 7,000 meters is barely enough."

    "As he said this, Ju Tao rubbed his hands in embarrassment: "Mr. Zhuang, would you mind taking a few of us to have a look so that I can estimate the configuration of the equipment?"

    "Didn't your old man tell you? A prototype of the new model has been built, and it hasn't been tested yet. Why are you anxious?"

    "Oh, Mr. Zhuang, it's not like you don't know that my old man is thinking about his grandson right now. How could he tell me in such detail? Okay, Brother Ye, just take me to have a look."

    When Ju Tao said this, Zhuang Jianye could only nod: "It's too late today, I'll take you there tomorrow."

    "That's it." Ju Tao slapped his thigh excitedly, then picked up the cup and poured the full glass of wine into his mouth. After swallowing, he opened the wine bottle and patted his chest: "Don't worry  Brother Ye, I understand the old rules, and tomorrow I will make sure that the new model will make the photos more beautiful than the beautiful lady."

    After finishing speaking, Ju Tao rolled his eyes and then fell onto the wine table with a clang.

    Zhuang Jianye sighed, thinking that this guy was ruthless enough. He was afraid that he would be too excited to sleep at night, so he would just drink him down, but let alone that, it was indeed a good idea.

    ¡­¡­

    The next day, Zhuang Jianye asked a van from the Xiping Factory to pick up Ju Tao and the others, and then personally took them to the research and development of the new Yun 5

    Went to the workshop, and after a group of people walked in through the side door, they saw an unpainted yellow biplane parked in the huge factory building, with several people wearing safety helmets pointing in front of the aircraft.

    Seeing Zhuang Jianye and others coming in, a tall, bookish old man came over quickly and greeted Zhuang Jianye with a smile: "Oh, Xiaozhuang, you are no longer modifying the aircraft, you are simply breaking up the heavy equipment."  I made a new model.¡±

    The visitor is none other than Lin Guanghua¡¯s mentor, Professor Ding Laixiang, a major in flight structure mechanics at Xihang University.

    Zhuang Jianye didn't expect Professor Ding to come, and couldn't help but be startled. Lin Guanghua, who was following closely, quickly explained: "Didn't our Y-5 modified aircraft use several new airfoil results? Professor Ding came over to see how they were used."  Like this, so I rushed here from Cotton early in the morning."

    Hearing this, Zhuang Jianye suddenly realized that the modified Yun 5 had indeed applied a lot of the research results obtained by Ding Laixiang in the wind tunnel over the years to enhance the wing structure, increase the overall lift, and improve the overall controllability.

    The reason why we have spared no effort in this aspect is very simple. The Tengfei Factory¡¯s modified Y-5 is equipped with an 882-kilowatt Honeywell turboprop engine.

    ? Equivalent to 1,200 horsepower. Compared with the piston 5 engine with only 820 horsepower, not only the power is greatly improved, but the overall weight is also reduced by 5%.

    As a result, the top speed of the Yun-5 increased from 256 kilometers per hour to 295 kilometers per hour. As the speed increased, the original body structure, especially the wing structure, was naturally unable to withstand the increase in speed.  aerodynamic changes.

    Based on this, it was imperative to re-develop the Y-5 wing. Therefore, the original canvas skin was replaced with a full metal skin. The internal structure was also greatly improved, and we couldn't help but add more  In order to improve the internal structural strength, two wing fuel tanks were also added to increase the range of the Y-5.

    At the same time, the flap behind the wing??It has been deeply optimized to make it more maneuverable, especially at low altitudes, low speeds and short take-off and landing capabilities. In theory, it is no worse than the Y-5 before the engine change.

    In addition, in order to improve flight performance and save fuel, the improved Y-5 also uses two integrated winglets, which makes the high-altitude flight performance of the Y-5 jump up by more than one level compared to the old Y-5.

    Coupled with the wing de-icing and reinforced landing gear sent to Yonghong Factory, the improved Y-5 not only has a maximum ceiling of 7,300 meters, but can theoretically be used to take off and land anywhere in the country, even in Qinghai-Tibet  The high altitude areas of the plateau are no exception.

    Because of this, when Ding Laixiang saw the prototype of the improved Y-5, he was overall very satisfied. In any case, this kind of aircraft that can be used nationwide is still blank in China, especially in the Qinghai-Tibet Plateau and border areas.  Transportation across mountain ranges in northern and southern Xinjiang has great application potential.

    Of course, the most important thing is the model structure used in this model. It can be regarded as a concentrated display of Ding Laixiang's research results over the years, so the old man is more concerned about it than anyone else. After all, he can see that his research results can be applied.  For a technology worker, it is the greatest happiness.

    So Ding Laixiang was very happy to see Zhuang Jianye, and even greeted Ju Tao and others politely. When Ju Tao and others took the photographic equipment and started working around the improved Y-5 prototype in front of them, Ding Laixiang couldn't help but  Nodding: "It's time to take some photos, it's time to take some photos. Taking out these photos in a few years will be a very good memory."

    Ding Laixiang watched Ju Tao and the others arranging lights and camera positions. He very much agreed with Zhuang Jianye's approach. After praising him, he frowned and said, "Xiao Zhuang, I just took a closer look at your new camera.  The shape, everything else is very good, but there is one thing I think you have gone too far."

    Upon hearing this, Zhuang Jianye felt that the old professor was about to give advice. Looking at Lin Guanghua who was smiling bitterly next to him, he knew that the two people had probably talked before, so he nodded quickly: "Professor Ding, you said, we don't have enough experience here."  , you, an old airline, should help us check things out."

    "There's nothing specific. It's just that your cabin is too luxurious. I personally don't think it's necessary. As for airplanes, the most important thing is transportation. You make it luxurious, not to mention wasteful, and it also increases the overall weight for no reason.  , some gains outweigh the losses"

    Professor Ding said very seriously, and Zhuang Jianye listened with a serious face. At this moment, a girl suddenly exclaimed from the cockpit of the plane: "Oh my god, it's so comfortable in here. Can I sleep in it today?"  ?¡±

    Professor Ding, who was giving his opinion, immediately darkened his face.
