715 In order to transport ten, the engine that should be introduced can only be introduced (60/100)

, the fastest update of the latest chapter of the reborn military industry!"Brother Kai, I'm here ......"

"Brother Kai, the base asked us to gather here, what is the matter?"

"Brother Kai, Lao Wang, are they crazy? We can take the train back by ourselves, and it will be a waste of ...... to take the plane."

At the Capital International Airport, a group of young people wearing uniform red down jackets and embroidered with the word "Dongfeng" on their chests gradually gathered in the waiting hall, causing many passengers to stop and watch.

The uniform costume is too sassy.

And it's also an expensive down jacket.

Liang Yao and the others widened their eyes, they didn't expect Xie Kai to be the leader of this group of young people.

"Everyone pays attention to discipline, we represent the image of the unit outside!" Xie Kai rectified the discipline, saw these familiar faces, went to college for half a year, and was still childish, but a lot calmer.

Then he pointed to Liang Yao and the others behind him, "Familiarize yourself, these are my classmates in the dormitory, and they are also our people......"

"Hello, my name is Mao Wenfeng, the aircraft designer of the University of Aeronautics and Astronautics, just call me Maozi. Mao Zi took the initiative to stretch out his hand to Liang Yao.

The others also greeted each other, and when Xie Kai didn't speak before, almost no one paid attention to Liang Yao and the others.

The children of 404 have always been very xenophobic.

"Okay, everyone is due, Maozi, assemble the team and get ready to board. Xie Kai shouted to Mao Wenfeng, who was dancing with his eyebrows and talking to a few people around him.

Mao Zi went to Aerospace University, Xie Kai was a little surprised at first, thinking that he had gone to Huaqing, but he didn't feel weird.

Theoretically, all the original regrets will not appear again.

"Which flight?" The announcement didn't inform you which flight had boarded. Besides, we didn't change the boarding pass either......" Liang Yao and the others saw that everyone else was lining up and walking towards the boarding gate, and asked Xie Kai in a low voice.

Mao Zi pulled him, "Just follow along." Let's fly, we don't need a plane, we have our own plane. ”

"Really?"

Liang Yao couldn't believe it at all.

If you fly a plane, you can get the old nose money.

At the boarding gate, Mao Wenfeng and Wang Xiaole counted the number of people, and then watched them get on the shuttle bus to ensure that their people got on the plane, and also to ensure that no outsiders would get on the plane.

"Yun Ten?" Liang Yao asked.

He had heard the name of Yun Ten many times, but he had never seen it, let alone sat on it.

Now it's directly under Yun Shi, and I'm a little distracted.

"Of course, our unit built it, and this is the second prototype for flying. Mao Zi said proudly, "Domestically made!"

"Boss, is this plane really made in our country? doesn't it mean that our country can't make it?" asked Cheng Xiaofeng.

He didn't know anything about airplanes, but there had been a lot of reports in the newspapers about the Yun-10 project.

Later, there were basically no reports about Yun Shi in the newspapers.

Originally, they could have asked Xie Kai everything, but now, they found that Xie Kai's identity was not as simple as they thought, so they were embarrassed to ask Xie Kai again, didn't they see that Xie Kai was thinking about things all the way?

"Who told you that our country can't make it? Although there is still a certain technological gap compared with the level of foreign countries, and even the service life is much worse, all the parts and components of this aircraft are made by our country's units themselves. Mao Wenfeng proudly introduced the situation of the Yun 10, "At the beginning, the country could not take out the money for follow-up improvement and test flights, and dismounted the Yun 10, and our unit took over and continued to test and improve the third flight, and now it is estimated that it will be ......produced."

The others listened attentively.

This unit is likely to be their lifelong work unit in the future.

Until they got on the plane, more than 50 people were on the plane, and there were still a large number of empty positions, and Liang Yao and the others had not calmed down.

Feeling that Yun Ten was getting faster and faster on the runway, he shook slightly, and then looked outside, he had already left the runway and flew towards the sky.

Liang Yao and the others were all on a plane for the first time, and they were nervous, looking at the people around them, and forcibly calming down.

Even though he had countless questions, he couldn't ask.

Xie Kai: What is the purpose of their unit?

Is it really to unveil the mystery of this unit to them now?

According to Liang Yao's understanding, it was impossible for Hongqi Machinery Factory to let them know the real situation while they were still in school.

The confidential unit has the principle of a confidential unit.

Until the plane landed, Liang Yao didn't understand what the other party's purpose was.

"Isn't this a civil aviation airport?" Liang Yao came down and saw that the scene around the airport was not like the situation at the Capital International Airport, there were several larger planes around, but there were no signs.

"Qin Fei's test airfield. Xie Kai explained to everyone, "This time, our unit organized everyone to learn about some of the related industries of our unit. So that everyone has a clear goal when they study. ”

"Really?" the crowd was surprised.

Liang Yao and others, you look at me, I look at you, I don't know what the situation is.

"Rest at the Qin Fei Guest House tonight, there is our Yunshi design team and assembly workshop here, visit the aircraft design process, testing process and final assembly production line tomorrow, and visit the big press ......workshop the day after tomorrow," Xie Kai gave a brief introduction to the itinerary of the last few days, "Okay, get in the car." ”

"You personally lead the team?" The person who came to pick everyone up was actually Cheng Bu, the vice president.

"Mr. Cheng, why are you here?" Xie Kai hadn't seen Cheng from time to time before, only seeing three or two buses.

"Tell you about your plane. Cheng grinned from time to time and said, "The final assembly is almost complete, but the layout inside, whether it is according to the standard seats of the passenger plane or the layout of the private jet, we are a little undecided, I want to ask your opinion." ”

Xie Kai was stunned.

He forgot that the Yun-10 that was being produced was taken from Kaisheng Company.

At the base, Yang Qian did not agree to the special budget and did not allocate funds to produce the third test flight aircraft.

The flight time of the second Yun-10 is now more than 400 hours, and according to the original estimate, the safe flight time is more than 500 hours.

The newly produced one is estimated to be not much stronger.

"What is the expected safe flight time?" Xie Kai asked.

Cheng was a little embarrassed from time to time, but he couldn't help but say, "About a thousand hours." After 800 hours of flight time, it was time for a major overhaul. As long as the large press is put into production, the forged frame beam will be replaced, and the service life will be increased to at least 3000 hours. ”

"Then follow the private jets. When the time comes, the aircraft will be presented to our customers as a sample. A lot of customers need private jets. Xie Kai said.

Yun Shi's private jet, Xie Kai thinks, is still more promising.

It's just that the current security performance is really not reassuring.

Hundreds of hours of safe flight time, he himself is embarrassed to sell to others.

"By the way, since it's a private jet, you have to pay attention to the interior. And the layout inside...... Private jets do not pursue payload. Ride comfort must be taken into account. ”

Cheng nodded from time to time.

As a large passenger aircraft, the Y-10 is not too suitable.

However, as a business jet, it can still have a lot of prospects.

"What else is the problem?" Xie Kai asked when he saw that Cheng wanted to stop talking from time to time. "Mr. Cheng, if there is a problem, put it forward directly, we must make the Yun10 model perfect faster, and at the same time develop a new model. ”

Although Yun-10 is a 100-ton large aircraft, it is relatively embarrassing.

The world's largest large aircraft, with a maximum take-off weight of several hundred tons, and a deadweight of more than 200 tons.

China still has a long way to go from being the top of the world.

"Engine. At the beginning of the 10th Fortune Campaign, we imported a total of six engines from the United States. If production continues, the engine will not be enough. Cheng explained from time to time, "The domestically produced turbofan eight has always been afraid to use it because of the manufacturing defects of the blades. ”

"The big press will be put into production right away. Xie Kai sighed.

Whether it is the main structure of Yunshi or the core parts of the engine, they are waiting for the big press.

"A new one will be produced after the year, or you will have to use the imported engine in front of you, and then you will have to wait until the end of the 10th flight before the engine can be installed...... Either you can only use domestic turbofans ......"

The domestic turbofan eight has almost come to a standstill in recent years.

Although the test work has been largely completed before, not many flight tests have been carried out.

The engine is the heart of the aircraft.

The Yun-10 uses four engines, and if all domestic engines are used, once something goes wrong, it will have a serious impact on the development of the entire aircraft project.

"We'll talk about that then. The production of new and improved models, safe flight, is the first element. The engine, too, has to be tested by other aircraft first......" Xie Kai's brow furrowed even tighter.

The engine is a hard injury.

On the power plant, it has been tackling key problems.

"We suggest that we can continue to introduce a few American engines......," Cheng said from time to time.

"Lao Zheng, what is their attitude?" Xie Kai asked.

Cheng smiled wryly from time to time and did not speak.

If Zheng Yucheng and the others could agree, would he tell Xie Kai about it?

"Specifically, let's wait until tomorrow to see the situation. Xie Kai sighed, the problem of heart disease in the aviation system is not so easy to solve.

If it really doesn't work, we can only introduce engine emergency from abroad.

Although the turbofan-8 engine has been tested on the Boeing 707 for dozens of hours, it does not mean that the turbofan-8 can be fully used in the flight of the Y-10.

Whether it is a Boeing 707 or a Yun-10, it adopts a four-engine structure.

In the previous test flights, only one turbofan-8 was mounted on the Boeing 707 used for flight tests, and even when stopped, there were three engines that provided enough thrust to keep the flight stable.

Mr. Ma also felt that if he wanted Yun Shi to continue, he still had to introduce engines from the United States first. Wait until the performance of our engine meets the demand, and then replace our domestic engine ......"

"If you have to, you should bring it from abroad, and you should bring it from abroad. The improvement of Yun 10 must not be stopped. We've invested too much. Xie Kai took a deep breath.
