"It's not too early, let's rest first, there are more opportunities later. Seeing that Xie Kai was reluctant to speak, Zheng Yucheng looked out the window, not knowing when, the sky had already dawned.

Raising his wrist to look at his watch, it was already past seven o'clock.

Rongcheng will be lit up around five o'clock in summer, and time flies too quickly.

Lu Yuanyuan looked at Xie Kai with a resentful expression, she really wanted Xie Kai to seriously and carefully introduce the characteristics of this pneumatic layout that is somewhat similar to Super Seven, but has a very different one.

This is very helpful for a researcher like her who is engaged in structural design.

"Why don't you come to my room and we'll talk alone?" Xie Kai said with a smile on his face and joked at Lu Yuanyuan.

Smiles appeared on the faces of the others, Xie Kai was obviously joking, and said that he didn't want to say it, everyone knew that this was something that was absolutely confidential.

"Okay, which room, why don't we go now?" Lu Yuanyuan didn't care at all, "Don't worry, what you do to your sister, my sister doesn't mind." Anyway, you're unmarried, I'm not married......"

Xie Kai couldn't wait to give himself a mouthful.

The woman is now eyeing herself.

"Okay, let's rest first, have some breakfast, wake up after a while, and let the hotel arrange a car to send everyone back." Zheng Yucheng said.

Most nodded happily.

"How do you know this? Do you really want to do this?" Zheng Yucheng asked Xie Kai during the meal.

"It's definitely going to be done, but it depends on when it's done. Xie Kai nodded and said, "There are many conditions that are not available now, but we can start to make preparations." Validation of the entire project. ”

Neither the technical base nor the capital is what the current 404 can afford.

"Mr. Huo, what is the origin of that kid?" Lu Yuanyuan is more lively, plus the entire project team, there are only two girls, she and Luo Ting, everyone takes care of them, and she knows how to get along with people better than Luo Ting.

Huo Haiyuan looked at Xie Kai, who was talking to Zheng Yucheng in a low voice while eating not far away, and sighed, "Until now, I haven't figured out what he is from." His father was just an ordinary engineer, and now he has entered the core management of 404; he helped his mother contract the 404 quilt factory, and then forcibly sold millions of work clothes to 132 factory, two, one, 541 and other units; it is said that he has another unit......

Huo Haiyuan saw that the people around him were listening with their ears pricked up, and even Yang Wei, who had never liked gossip, pricked up his ears to listen.

"Is there anything else? Director Zheng and the other leaders were tossed by him as a child?" Lu Yuanyuan's eyes widened.

"Is he an ordinary child? Teach you a lesson, listen to it so intrigued, and buy you in a few words......" Huo Haiyuan smiled bitterly, even he, now 404 said that he didn't want him, he wouldn't agree. "Alright, hurry up and eat, and go back to work. Strive for us to be a part of that project. It's okay not to offend him, otherwise I won't be able to help me intercede at that time. ”

Everyone was shocked and had mixed tastes.

When they were as old as Xie Kai, they were still confused and didn't know what university to go to.

After breakfast, the Siyudu team was reluctant to stay here to rest, they hoped that Zheng Yucheng could arrange a car and go back to work now.

The sooner the current work is completed, the sooner you can get in touch with the stealth fighter project that Xie Kai said, everyone hasn't slept all night, and they don't feel sleepy at all.

"You're not going back, I'm going to open a few rooms for you. Most of them got in the car, but Huo Haiyuan and Yang Wei, as well as Lu Yuanyuan and Qiao Ping'an, did not leave.

"Leader, we want to know some details about our stealth fighter. Huo Haiyuan represented several people and said to Zheng Yucheng.

Zheng Yucheng looked at Xie Kai, who frowned.

"We have all learned the rules of confidentiality, and we will never divulge anything, and we know that we can give more consideration to the current work in the process of work. Yang Wei explained.

Zheng Yucheng knew a fart, and he only found out about it today.

Xie Kai knew that Yang Wei and the others had already become curious, and if they didn't introduce them to something, it would definitely make them unable to work with peace of mind.

Several people returned to the room where Xie Kai and Zheng Yucheng lived.

The room is a very ordinary double room, and seeing this situation, everyone really believes that Zheng Yucheng is doing such a high standard because he values them.

"The stealth fighter is the next generation of the No. 10 project, and now the domestic No. 10 project has just started, and the drawing design stage has not yet been completed. Due to the special situation, our unit can raise funds and set up projects independently, so there is no such problem. However, the difficulty of development, everyone must be fully prepared. Xie Kai didn't talk about technology first, but put the difficulties in front of everyone.

"Back then, we had two bombs and one satellite, and we didn't have any foundation in China. Lu Yuanyuan said, "Little leader, don't worry, we have to go up if there are difficulties, and we have to go up if there are no difficulties to create difficulties." ”

One sentence amused everyone.

Xie Kai was about to laugh.

Lu Yuanyuan's thinking is closer to him.

"Several major features have been introduced to you, but it has taken decades for some countries to solve these major characteristics. We can't be pessimistic, let alone optimistic. The investment in this project will be at least tens of billions, and it will have to be comprehensively improved in advanced materials, microelectronics, computers, mechatronics, manufacturing processes, and structural processes. Xie Kai said.

"Sue~" There was a gasp in the room.

"How much money do we have?" asked Zheng Yucheng.

"It's not now, it's a one-time investment. Xie Kai said, "In terms of stealth, I have already introduced to you, the sketch I drew before is what I got from abroad, and there is only one general situation, whether it can be realized, our designers need to verify and improve the design." ”

Xie Kai said this, and Lu Yuanyuan was a little disappointed.

She also knows that this is normal, and the price paid for getting such a shape and structure can be imagined.

"In fact, there are not too many choices for these technologies in the world, such as full-motion double vertical tail, DSI bulging air intake, and canard aerodynamic layout with pointed arch edge strips on the upper anti-canard wings. As for the engine, it must have a turbofan engine with a thrust-to-weight ratio of more than 10, and it also needs to have a tail vector nozzle......" Xie Kai directly took out the outline structure of the J-20.

The aerodynamic layout of the J-20 is the world's first canard wing layout, integrating the relevant technologies of many excellent fighters in the world.

Although compared with the United States, it is not as advanced as the United States, Xie Kai knows that the J-20 is mainly poor in the power system and electronic system, as long as these things are improved, it is not a problem for the J-20 to double its combat capability.

The turbofan-10 engine, which has just been mass-produced, is just a backup plan, and the real use is actually the turbofan-15 with better performance.

Everyone is an expert in this area, even if they have not developed it, what Xie Kai introduced made them serious.

It's not a bit difficult.

"The stealth fighter project has very high requirements for situational awareness, information confrontation, and cooperative operations, which is completely blank in China. To engage in this project, everyone must be fully mentally prepared, at least for more than 10 years, or even 20 or 30 years. Xie Kai said, "The main goals of this project are four - to build a domestic cross-generation new machine, lead the development of technology, innovate the R&D system, and build an excellent team." Because you are young and the best among your peers, Director Zheng selected you and will be based on your team. ”

"If you can really do it, let alone twenty years, thirty years, even if it's a lifetime, it's worth it. Yang Wei sighed.

"yes, it's worth it when you die. Huo Haiyuan was a little worried.

He was in his early fifties.

It's really thirty years, and if you can't do it yourself, you can't see it.

"But these technical indicators are too high, not a little difficult, and completely desperate. Lu Yuanyuan's face was really desperate.

"So, you don't need to create difficulties. Xie Kai said with a grin.

Seeing that everyone's faces were full of despair, especially Yang Wei, who had completely lost the interest he had before, Xie Kai was worried that they would be hit, if something happened to Yang Wei, would this be okay?

Who will do the stealth fighter of the flower planter?

Hurriedly cheered everyone up, "Don't be scared by these performance indicators. The overall level of science and technology in China is developing. This project, just the preliminary demonstration work, it takes a long time, as well as the overall design and other work, to complete this, it will take at least five years, and at that time, maybe a lot of technology can be introduced from the outside. ”

Xie Kai's words ignited hope for everyone.

"Defense technology can't be bought. Even if we are now working with the United States as a model of peace, with the Soviet Union posing less and less of a threat to the United States, isn't the progress almost at a standstill?" Yang Wei said with a wry smile, "This kind of technology cannot be provided to others in any country in the world." If you can really get it, the price you pay will be beyond imagination. ”

Xie Kai didn't expect that Yang Wei would have such an understanding at such a young age.

It is no wonder that he was able to serve as the chief designer of the Thunder in his early thirties, and later became the chief engineer of the J-20.

"Of course. National defense is not bought by buying, our third brother's family next door buys it every year, what can we build now?" Xie Kai nodded, he very much agreed with such a statement. "Even if you can get it, it's something that's backward to others and used for blackmail. ”

But now many people in China still have great hopes for the United States, and they have to wait until the public knowledge cultivated by the West to propagate hope in China, and the thing that wants to be fully Westernized will appear, so that the Chinese people will wake up.

Imperialism's desire to kill itself will never die.

"So, let's do it ourselves, are you not afraid of difficulties, are you not afraid that it may be fruitless for a lifetime?" Xie Kai asked everyone.
