Take Off My Aviation Era

, The fastest update to take off the latest chapter of my aviation era!

"This one……"

As soon as Zhuang Jianye wanted to answer, he felt that the tip of his nose was full of wine. He looked at it again, okay, the wine bottle in Ju Tao's hand was still filling the quilt, all of which overflowed without noticing it.

Seeing Zhuang Jianye’s strange expression, Ju Tao immediately noticed that his wine bottle hadn’t been retrieved. He quickly yelled, took the wine bottle down, smiled embarrassedly, and said without embarrassment, “Isn’t this because you said there is a way? Yes, hehe, by the way, Mr. Zhuang, I heard from the old man at home saying that the factory is going to build its own airplanes, isn't it this new model?"

"Hi~~ Your kid's news is pretty good, yes, this is the new model." Zhuang Jianye didn't hide it. It has been a while since the Ascendas factory modified the Yun 5, especially the wing of the Yonghong factory. After the technology of ice and landing gear, the progress of 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 Western Air University for a series of body fatigue tests. If everything goes well, it can be completed before the end of the year. A series of tests, and then enter the first flight.

Seeing Zhuang Jianye nodded and confessed, Ju Tao's fat face immediately turned into a chrysanthemum with a smile, and hurriedly asked: "How high can I fly?"

"The design ceiling is 7320 meters."

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

He said that Ju Tao rubbed his hands embarrassedly: "President Zhuang, it is not convenient for you to take a few of us. I can estimate how to configure the equipment?"

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

"Oh, Mr. Zhuang, you don't know that my old man is full of grandchildren now. How could he tell me so carefully, OK, Brother Ye, just take me to see."

When Ju Tao said so, Zhuang Jianye could only nod his head: "Today is too late, I will take you there tomorrow."

"That's it." Ju Tao patted his thigh with excitement, and immediately picked up the glass and poured a full glass of wine into his mouth. After swallowing, he punched the wine and patted his chest: "Don't worry... …Brother Ye, I understand the old rules. Tomorrow, I promise to shoot the new model more beautifully than the big beauties."

After speaking, Ju Tao rolled his eyes, and then crashed on the wine table.

Zhuang Jianye sighed, and said that this product was cruel enough. He was afraid that he would be too excited to sleep at night, so he would pour himself out, but let alone say it, it was indeed a good way.

...

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

When I went to the workshop, when a group of people walked in through the side door, they saw an unpainted yellow biplane, parked in the huge factory building, and a few people wearing safety helmets were pointing in front of the plane.

Seeing Zhuang Jianye and others coming in, a bookish and thin old man hurriedly greeted him and greeted Zhuang Jianye with a smile: "Oh, Xiao Zhuang, you are not modifying the plane anymore, you are simply breaking up. Made a new model."

The person here is not someone else, he is really Lin Guanghua’s tutor, Ding Laixiang and Professor Ding from Xihang University, majoring in flight structure mechanics.

Zhuang Jianye didn’t expect Professor Ding to come, he couldn’t help but was taken aback. Lin Guanghua, who was following him, quickly explained: “Did we not use a few new airfoil results for our Yun-5 modified machine? Professor Ding came to see how the application is. Well, so I came over from Cotton early in the morning."

Hearing this, Zhuang Jianye suddenly realized that the modified Yun 5 did apply a lot of research results Ding Laixiang had made in the wind tunnel group over the years in order to enhance the wing structure, increase the overall lift, and improve the overall handling.

The reason for spare no effort in this regard is simple, the modified Yun 5 of the Ascendas plant was replaced with a 882-kilowatt Honeywell turboprop engine.

Equivalent to 1200 horsepower, compared with the 820 horsepower Piston 5 engine, not only the power has been greatly improved, but the overall weight has also been reduced by 5%.

The result of this is that Yunwu has increased from a maximum speed of 256 kilometers per hour to 295 kilometers per hour. With the increase in speed, the original airframe structure, especially the wing structure, cannot withstand the increase in speed. The aerodynamic changes.

Based on this, the re-development of the Yun-5 wing is imperative, so the original canvas skin was replaced by a full-metal skin with a full-metal skin. The internal structure has also been greatly improved, which can’t help but increase. To improve the internal structural strength, two wing fuel tanks were added to increase the range of Yunwu.

At the same time, the **** behind the wings have also been deeply optimized, making it more maneuverable, especially at low altitude and low speed and short take-off and landing capabilities, theoretically not 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 Yun-5, which makes the Yun-5's high-altitude flight performance more than one level higher than that of the old Yun-5.

Coupled with the wing deicing and enhanced landing gear obtained by the Yonghong factory, the improved Yun-5 not only has a maximum ceiling of 7,300 meters, it can theoretically be used in any place in the country, even Qinghai-Tibet The high-altitude areas of the plateau are no exception.

Because of this, when Ding Laixiang saw the improved Yun-5 prototype, he was very satisfied overall. In any case, this kind of aircraft that can be used throughout the country is still blank in the country, especially in the Qinghai-Tibet Plateau and border regions. Transportation across the mountains in the north and south of Xinjiang has great application potential.

Of course, the most important thing is the structure of the model 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 than anyone else. After all, he can see that his research results can be applied. For a science and technology worker, it is the greatest happiness.

So I was very happy to meet Zhuang Jianye and Ding Laixiang. He even greeted Ju Tao and others politely a few times, waiting for Ju Tao and others to take the photographic equipment and start surrounding the improved Yun 5 prototype in front of them. readwn.com~ Ding Laixiang can't help but nodded: "It's time to take some photos, it's time to take some photos, waiting a few years to take out these photos is a very good memory."

Ding Laixiang looked at Ju Tao and they set up the lights and set the camera position. He agreed with Zhuang Jianye's approach. After complimenting him, he frowned and said: "Xiao Zhuang, I just took a closer look at your new machine. Type, the others are very good, but there is one thing I think you are overkill.

When Zhuang Jianye heard this, the old professor wanted to make comments, and when he looked at Lin Guanghua, who was smiling bitterly next to him, he knew that the two people had talked about 80% before, so he nodded quickly: "Professor Ding, you said that we have no experience here. , You, the old airline, have to take good care of us."

"There is nothing more specific, that is, your cabins are too luxurious. I personally think it is unnecessary. Airplanes are the most important thing for transportation. You make it luxurious and wasteful. For nothing, you also increase the overall weight. , Some of the gains outweigh the losses..."

Professor Ding said 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 really comfortable inside. Can I sleep in it today? ?"

Professor Ding, who was making comments, immediately turned black.
