(3/5 for @liwers_loor League)

"Do you really want to take over research projects on plugged rocket engines and refueling engines? You'll have to think about it, it's not much easier than the turbofan engine you're working on right now! In the face of Liu Yijiu, who suddenly took the initiative to accept the most critical engine project in aerospace again, the old man was a little surprised.

Liu Yijiu's relationship with the Ministry of Aerospace Industry is not very good, and he has never interfered in this research.

Especially after the Ninth Academy got involved in missile research, if it were not for the fact that the export of Dongfeng-3 missiles could give a large amount of money to aerospace, and Qian Xuesen himself was a big man with great influence in the Ministry of Aerospace Industry, the Ministry of Aerospace Industry would not agree.

At the beginning, they took the initiative to find the Ninth Academy, which was to run for the funds of the Ninth Academy, as well as the material technology and manufacturing and processing capacity of the Ninth Academy.

However, the Ninth Courtyard also had no surplus grain in the landlord's house on top of the things that were lacking in these other units, so they rudely refused.

In addition, Liu Yijiu changed his tricks to get people from the Ministry of Aerospace Industry, which made him even more unpopular in the Ministry of Aerospace Industry.

After being reprimanded by Long Yaohua, Liu Yijiu deeply reflected on himself.

Now it is the most urgent thing to improve China's national defense science and technology, and as for the rest, they don't need to think so much about it.

After hearing the old man's question, he immediately said to the old man very sincerely, "Chief, no matter what, this is a key project of our military industrial system. Moreover, the whole project can be stopped. But the core doesn't. If the power does not work, our rocket will not develop much......"

Once it is really possible to solve the second and third stage engines of the DF-6, the missile technology and performance of the republic. It will definitely reach a height that will shock the world.

In particular, the plug engine, once the technical problem is solved, can effectively shorten the length of the missile.

Without such an advanced engine, even a medium-range strategic missile with a range of less than 3,000 kilometers like the DF-3 has a staggering 30-meter length!

The so-called plug engine is the use of many small engines in a circle to replace the original single large engine. In this way, the length of the large engine, which was originally intended to achieve output efficiency, can be shortened to shorten the length of the entire missile. This is a very advanced second-stage rocket engine, which is also in the development stage of the United States and the Soviet Union. It has not been successful at the moment.

China is actually on the same level as the United States and the Soviet Union.

"In this matter, you have to go to the Ministry of Aerospace Industry to find Ren Xinmin, director of their Science and Technology Committee......" The old man was still very satisfied with Liu Yijiu's attitude.

It can be regarded as Long Yaohua not scolding him in vain.

As for whether Liu Yijiu still has the same worried mind as before, no one can do anything.

Under the personal leadership of Long Yaohua. Liu Yijiu went to the Ministry of Aerospace Industry. Since this guy has become the target of key defense in the Ministry of Aerospace Industry, as soon as he saw him, Ren Xinmin said to Liu Yijiu with a gloomy face: "Director Liu, if you want someone, as long as you say hello, do we dare not give it?" As for bringing in the Chief of the General Staff of Long? ”

was so sarcastic, Liu Yijiu could only smile bitterly.

"Director Ren, Xiao Liu is not here to dig people this time. This kind of thing. They have long since stopped doing it...... Long Yaohua hurriedly helped Liu Yijiu to say good things to Ren Xinmin.

"Chief, don't help him lie. I can't tolerate sand in my eyes, you know, this kid borrowed a group of people from us when he exported Dongfeng-3, saying that it was cooperation with aerospace, or in the Seventh Academy, and now none of them have come back...... "I can't find Qian Xuesen, Ren Xinmin caught the mastermind, but it wasn't so easy to pass."

Looking at the old man in front of him, one of the four elders of aerospace with a thin figure and thick lenses, Liu Yijiu felt a little embarrassed.

Although it is also for the sake of the country, it has indeed taken away a lot of core talents trained in aerospace, and no one will give him a good face.

When Long Yaohua heard Ren Xinmin's words, he could only laugh dryly twice, and he couldn't say anything about this matter.

"Old Ren, I'm not here to apologize......" Liu Yijiu knew that this old man was not easy to deal with, and if he wanted to get the engine of Dongfeng-6, he had to go through this old man, he was the chief designer of Dongfeng-6, and the work had been going on for several years, even if there was no appropriation, this old man's group of people continued to design.

Many of the people he got away were brought out by the old man Ren Xinmin.

Liu Yijiu is also ruthless enough, most of the people are the core backbone of forty to fifty, all of these people are from the two bombs and one star project, and before the big ****, they also had a very systematic education.

Such people in all departments are the most valuable.

Otherwise, he would not have caused such a big resentment if he let such a technician go.

"Hey, Director Liu, as long as you don't show up in the Ministry of Aerospace Industry, we can't afford to apologize, otherwise Minister Qian will have to count down my brother unit...... "Ren Xinmin's words made Liu Yijiu embarrassed.

This thing, it is estimated that it is very difficult to be a good person.

"Elder Ren, I know that what I do is not popular, but this time it is really for cooperation. Dongfeng-6 ...... "Liu Yijiu knew that it would definitely not be easy to convince this old man.

The older generation of technical bulls are very temperamental.

I dug up his own people, and this is how their research progress was delayed.

Hearing Liu Yijiu say Dongfeng-6, Ren Xinmin immediately became vigilant, "You want to take over this project?" Together with all the people? And said you weren't here to dig into our corners! I'm fighting with you today......"

While speaking, he was looking for something in his office to beat Liu Yijiu, but he happened to use the T-shaped ruler used to draw pictures on his desk, and regardless of the presence of Long Yaohua, the chief of the general staff, he grabbed it and waved it towards Liu Yijiu......

Liu Yijiu was so excited when he saw this old man, where did he dare to stand there, and shouted while dodging: "Old man, you can be leisurely, it's nothing to beat me, if you dodge your waist, it will be terrible......"

"Enough!" Long Yaohua is also afraid of hurting Ren Xinmin, Liu Yijiu is young, with thick skin and thick meat, but he doesn't care at all, it's normal to be beaten, who told him to dig up someone's team! "He's really here to talk about this, and the Ninth Academy is preparing to start the project of the plug engine and the refueling engine......"

"Didn't lie to me? Didn't he take this opportunity to poach our people? ”

The old man obviously didn't believe Liu Yijiu.

"If you don't believe him, can you believe me?"

"I don't even believe Minister Qian!" Ren Xinmin obviously did not give face to Long Yaohua, the chief of the General Staff.

"He came here today mainly to understand the situation. Didn't you keep saying that you shouldn't let the engine project follow suit? This kid thinks so too, didn't he dig up a lot of people from your aerospace side and prepare to compensate you......" Long Yaohua hurriedly explained when Ren Xinmin was not chasing Liu Yijiu.

"If you don't engage in Dongfeng-6, what's the use of those engines!" Although he knew that Liu Yijiu had studied with Du Bin and had been living in Minister Qian's house, Ren Xinmin didn't think that Liu Yijiu knew these things.

"It doesn't matter if you don't do Dongfeng-6, as long as you get a plug engine and a refueling engine, we can make a Dongfeng-9, or you can make a Dongfeng-99, in other words, Ren Lao, the range of Dongfeng-6 is really 19,000 kilometers? I'm skeptical! Liu Yijiu knew that this old man must not be dealt with by conventional means.

Sure enough, as soon as he said this, the old man was like a fighting, with his neck bent, his eyes widened, and his red neck glared at Liu Yijiu, "Boy, why do you doubt the authenticity of the design data?" If I don't say that I'm ugly today, I'll have to fight with you, anyway, I've lived enough......"

When Liu Yijiu heard this, the corners of his mouth twitched.

Is this old man really just because he poached people and treated himself like this?

It seems that he has not done anything else except for the astronauts.

Since '82, this old man has served as the director of the Aerospace Technology Committee, and he was the deputy minister of the Seventh Aircraft Department before, so he has no deep hatred!

Seeing the old man's panting getting thicker and thicker, Liu Yijiu felt a little uncomfortable, and immediately said, "The DF-3 with a diameter of 2.25 meters and a length of 24 meters has a range of only 2,800 kilometers, and the DF-5 with a diameter of 3.35 and a length of 32.5 meters is only 8,000 kilometers." The diameter of the DF-6 is said to be 4 meters, the length is 64 meters, and the weight does not exceed 400 tons, and the propellant fuel of the first and second stages is nitrous oxide and 2 methylhydrazine, which can be directly doubled or more? Also, according to our habits, shouldn't the DF-6 have a shorter range than the DF-7? I heard that the range of the DF-7 is only 15000 km? “

Liu Yijiu's suspicion is not very reasonable.

In fact, the DF-6 has never been successfully developed at all, and even the DF-6 that appeared in later generations is also newly developed.

Although there are rumors in the market that the Dongfeng-6 and Dongfeng-7 have been in service for a long time, Liu Yijiu knows that it is not true at all.

After the DF-5A with a range of more than 15,000 kilometers appeared on the 93 military parade on the 60th anniversary of the victory of the Anti-Japanese War, the DF-6 with a range of 21,000 kilometers was studied for a short time.

In these days, there is obviously no such technology.

"Boy, let me tell you, if it weren't for the lack of funds, as long as the engine came out, we would be able to get you the DF-6 with a range of 19,000 kilometers!" For a super deterrent artifact like Dongfeng-6, the old man is obviously in love.
