"This ......"

Zhuang Jianye just wanted to answer, but he felt that the tip of his nose was full of wine, and when he looked at it again, okay, the wine bottle in Ju Tao's hand was still pouring into the quilt vigorously, and it was all overflowing, and he didn't notice it.

Seeing Zhuang Jianye's strange expression, Ju Tao immediately noticed that his wine bottle was not returned, and hurriedly sighed, took the wine bottle down, smiled embarrassedly, and then said unashamedly: "Isn't this listening to you say that there is a way, happy, hehe, by the way, Mr. Zhuang, I heard the old man at home say that the factory is going to build its own aircraft, won't it be this new model?"

"Hi~~ Your kid is quite well-informed, that's right, it's this new model. "Zhuang Jianye is not hidden, Tengfei Factory has been modifying and transporting 5 for a while, especially after getting the wing de-icing and landing gear technology of Yonghong Factory, the progress of the modification is even more rapid.

Now the first prototype has been assembled, after a series of basic performance tests, it is ready to be sent to the test bench of Xihang University to do a series of fatigue tests, if everything goes well, a series of tests can be completed by the end of the year, and then enter the first flight.

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

"The design ceiling is 7,320 meters. ”

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

Saying that, Ju Tao rubbed his hands embarrassedly: "Mr. Zhuang, you see that it is inconvenient to take a few of us to see, I can estimate what the configuration of the equipment is?"

"Didn't your old man tell you? The new model has built a prototype, and it hasn't been tested yet, what are you anxious about?"

"Oh, Mr. Zhuang, you don't know my old man, he is now full of grandchildren, how can he tell me so much, okay, Brother Ye, take me to see. ”

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

"That's it. Ju Tao slapped his thigh excitedly, and then picked up the cup and poured a full glass of wine into his mouth, and after swallowing it, he slapped his chest and said: "Don't worry...... Brother Ye, I know the old rules, and tomorrow I promise to shoot the new model more beautiful than the big beauty. ”

After saying that, Ju Tao rolled his eyes, and then fell on the wine table with a bang.

Zhuang Jianye sighed, and said in his heart that this product is ruthless enough, and he is afraid that he will not be able to sleep at night when he is excited, so he will pour himself down, but not to mention, it is indeed a good way.

......

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

After the group walked in through the side door, they saw a yellow biplane that had not yet been painted, parked in the huge factory, and several people wearing hard hats were pointing in front of the plane.

Seeing Zhuang Jianye and the others coming in, a tall and thin old man who was full of books hurriedly greeted him, and greeted Zhuang Jianye with a smile: "Oh, Xiaozhuang, you are no longer modifying the plane, you are simply breaking up and redoing a new model." ”

The person who came was none other than Lin Guanghua's mentor, Ding Laixiang, a professor majoring in flight structural mechanics at Xihang University.

Zhuang Jianye didn't expect Professor Ding to come, so he couldn't help but be stunned for a moment, and Lin Guanghua, who followed closely, hurriedly explained: "Didn't our Yun-5 modified machine use a few new airfoil achievements, Professor Ding came over to see how the application was, so he rushed over from cotton early in the morning." ”

Hearing this, Zhuang Jianye suddenly realized that the modified Y-5 had indeed applied a lot of research results made by Ding Laixiang in the wind tunnel group over the years, so as to enhance the wing structure, increase the overall lift, and improve the overall handling.

The reason why no effort has been spared in this regard is simply that the modified Y-5 of the Ascendas plant has been replaced with an 882 kilowatt Honeywell turboprop engine.

Equivalent to 1,200 horsepower, compared to the 820 horsepower Piston 5 engine, not only the power has been greatly increased, but the overall weight has also been reduced by 5%.

As a result, the Y-5 has increased its maximum speed from 256 km/h to 295 km/h, and with the increase in speed, the original airframe structure, especially the wing structure, naturally cannot withstand the aerodynamic changes brought about by the increase in speed.

Based on this, it is imperative to redevelop the wings of the Y-5, so the original canvas skin was replaced with an all-metal skin, and the internal structure has also been greatly improved, which can not help but increase the internal structural strength, and also add two wing fuel tanks to improve the range of the Y-5.

At the same time, the flaps behind the wing have also been deeply optimized, making it more maneuverable, especially in low-altitude and low-speed and short take-off and landing capabilities, which are theoretically no worse than the Yun-5 before the change.

In addition, in order to improve flight performance and save fuel, two integrated winglets are also applied to the improved Y-5, so that the high-altitude flight performance of the Y-5 has jumped more than one level compared with the old Y-5.

Coupled with the wing de-icing and reinforced landing gear obtained by the Yonghong Factory, the improved Yun-5 not only has a maximum ceiling of 7,300 meters, but can theoretically be used for take-off and landing anywhere in the country, even in the high-altitude areas of the Qinghai-Tibet Plateau.

Because of this, when Ding Laixiang saw the prototype of the improved Y-5, the overall is still very satisfied, no matter what, this kind of aircraft that can be used throughout the country is still blank in the country, especially the Qinghai-Tibet Plateau and the northern and southern Xinjiang cross-mountain transportation in the border region, has great application potential.

Of course, the most important thing is the structure of the model applied to this model, which is a concentrated display of Ding Laixiang's research achievements over the years, so the old man is more concerned than anyone else, after all, it is the greatest happiness for a scientific and technological worker to see his research results can be applied.

So I was very happy to see Zhuang Jianye Ding Laixiang, and even said a few polite hellos to Ju Tao and others, and waited for Ju Tao and others to take the photographic equipment and start to work around the improved Yun-5 prototype in front of them, Ding Laixiang couldn't help but nodded: "It's time to take some photos, it's time to take some photos, and it's a very good memory to take out these photos in a few years." ”

Ding Laixiang looked at Ju Tao and they were arranging the lights and setting the camera position, and very much agreed with Zhuang Jianye's approach, and after praising it, he frowned and said: "Xiaozhuang, I took a closer look at your new model just now, and the others are very good, but there is one thing I think you are a little overkill." ”

Zhuang Jianye heard this, the old professor was about to give his opinion, and then looked at Lin Guanghua who was smiling bitterly next to him, and knew that the two of them had talked before, so he quickly nodded: "Professor Ding, you said that our side is inexperienced, and you, the old airline, should help us check the gates." ”

"There is nothing else specific, that is, your cabin is too luxurious, I personally think it is not necessary, the plane, the most important thing is transportation, you make it luxurious, not to mention the waste, it also increases the overall weight for no reason, and some of the gains outweigh the losses......"

Professor Ding said very seriously, Zhuang Jianye listened with a serious face, and at this moment, a girl's exclamation suddenly came from the cockpit of the plane: "Oh my God, it's so comfortable here, can I sleep in it today?"

Professor Ding, who was putting forward his opinion, immediately turned black with his old face.
