The engine has always been a hard wound of the republic, and no one can change it.

In the early sixties, after several five-year construction plans, the republic initially completed the industrialization of the country, and then began a decade-long turmoil, which ended more than a year earlier.

What can you do in the beginning?

Everything has to be done by yourself, and any kind of equipment is involved in many related industries. Just like Liu Yijiu wants to improve tank guns, steel, materials, smelting, mining and so on, a series of problems have to be solved.

Who can not have a headache at the thought of such a thing?

Zheng Hao has an even more headache, because these all require money.

In the Nine Courtyards, they only have 57 million on hand now, which is a huge amount of money in this era, but for these things they want to get, it is just a drop in the bucket. Now, if you want to develop, several other supporting factories must have new products that adapt to the market and can have very good sales.

Therefore, they don't want to count on the 30 million allocated by the superiors.

If we can't get the money in a short period of time, everything will have to stop after the Ninth Academy's 27 million dollars are spent, and the salaries of the personnel will not be paid.

"Xiao Liu, our base is now pressing everything on your plan!" When walking towards the interior of the base, Zheng Hao said to Liu Yijiu with a sad face.

Liu Yijiu shrugged. Spread your hands.

He's not omnipotent, either.

This state of affairs. It was also something he didn't expect.

Now, the only thing they can do is do their best to change that.

"By the way, Uncle Wang, when I first arrived at the base, I heard that we have turbocharged engines from France here, where are those things now? We can measure that. At the very least, there is a clear ...... for us in the direction of engine development: "The engine is a big problem and it must be done now."

If he wants to get a motorcycle, a car, or even a military vehicle, he has to start with the engine. Even, if they want to build a helicopter, they have to match the engine. The dismount of the Z-7 has a lot to do with the instability of the engine.

Infantry fighting vehicles and tank chassis can be slowed down for a while. As long as the engine is right, the rest will be easier.

"That? I'm still working on it in District 1. These engines are just the engines of civilian cars, we don't need them very well......" Wang Shunyi didn't expect Liu Yijiu to remember the engine he got at this time.

Most of the engines were sent to the basement level of the base.

"Okay, I'll go and discuss the improvement plan of the 59 tank with the 59th district first. I just don't know how this thing can the monkey T72...... "Liu Yijiu has a headache. To kill the monkey's T72, no matter how Wujiu changes, is a very headache.

"Five-nine engine if not replaced. The armor cannot be weighted much in this regard. Unless we can come up with more advanced and more defensive armor, in addition, it can only increase the attack power, the 100 mm caliber gun is not small in the same type, but for the new generation of tanks in the Soviet Union and the United States, it is obviously not enough......," Wang Shunyi reminded Liu Yijiu.

Liu Yijiu nodded.

"So we're going to have to get more powerful shells?" When Zheng Hao heard this, he immediately howled.

There has to be a new project again!

Ammunition is a huge hole, how much money to fill in. None of them are necessarily fruitful.

"Ammunition must be improved, especially armor-piercing shells...... Liu Yijiu nodded. Is there any uranium ore in the base that has been refined from nuclear raw materials? ”

The tail is stabilized and deshelled armor-piercing shells, which must be made, and if there is really no way, you can only get depleted uranium shells first.

This thing was the nemesis of the early third-generation tanks and was basically defenseless.

"Uranium-238?" Wang Shunyi immediately asked Liu Yijiu in surprise.

This is what remains after refining uranium-235, and now it is not known what it is for. Only seven out of every 1,000 uranium atoms are uranium-235, the rest are uranium-238.

Depleted uranium containing about 99.27% uranium-238 is a waste product used to refine nuclear raw materials.

There is no research on this depleted uranium in the country.

"Yes, that's the kind of waste. If there is the best purified one, we will use it to make depleted uranium alloy, and then make depleted uranium armor-piercing bullets......" Liu Yijiu's words frightened Wang Shunyi.

When Zheng Hao heard this, his eyes lit up, a single nuclear weapon!

He couldn't tell the difference between uranium-235 and uranium-238, and he didn't know that uranium-238 was very reflective.

"This is good, no matter how much money we have, we have to do it. Sure enough, he is worthy of being Qian Lao's proud protégé! Xiao Liu, you should have proposed to do this a long time ago. If our fighters carry a small nuclear bomb by then, the whole world will tremble! Who would dare to mess with us? Zheng Hao looked yearning, "Lao Wang, do you have these materials in our base?" Seems to be a researcher in this area, right? Hurry up to Xiao Liu, damn it, I am excited when I think of this......"

Hearing Zheng Hao's YY, Liu Yijiu hurriedly took two steps back, looking like I didn't know him.

Wang Shunyi was also made to cry and laugh by him.

This thing wants to install a 155-caliber heavy gun on the 59 tank, how much brains does it have to open to come up with such a whimsical plan?

Now that it's like this again, does he think that uranium can become nuclear raw material?

Doesn't he know that the refining of weapons-grade nuclear material is more difficult?

"Is there something wrong?" Zheng Hao saw the strange faces of the two of them, and immediately knew that there must be something wrong with this.

"Director Zheng, don't you know that uranium-238 is called depleted uranium? This substance is not very radioactive, and uranium-238 is the most common type of uranium. But it's not practical nuclear fuel. Although fission can also occur under the action of neutrons. Only fast neutrons can do this. Those uranium-238 that split in half produce some slow neutrons, which are not enough to cause further fission. Uranium-238 can be compared to damp wood: you can burn it, but it will eventually go out. Liu Yijiu said speechlessly.

It's terrible to be uneducated.

This statement was confirmed once again.

"Of course, it's not that this thing is useless, if you add this thing to the alloy, it will make the alloy more high. This we can use as a composite armor layer for our tanks. At the same time, if uranium-238 is hit with a fast neutron, after uranium-238 absorbs this fast neutron, it will not undergo fission, but it will change and become plutonium-239, which is another very practical nuclear raw material. material, and this method is very easy to achieve ......"

Zheng Hao was confused by Liu Yijiu's words. Didn't understand what he said at all.

Anyway, he understood that even if this kind of thing was made, it wouldn't be as powerful as an atomic bomb.

"You better stop popularizing these things for me. You are Qian Lao's protégé, you know these very well, and I am not a physicist......" Zheng Hao rolled his eyes and said, "Since it is not of much use." What are we doing here? Comrade Xiao Liu. You know our current financial constraints......"

This time it was Wang Shunyi's turn and Liu Yijiu to roll their eyes.

This thing is simply a typical pragmatist, if you tell him that this thing is made out, it is an atomic bomb, the yield is not large enough, the grenade shape is called a nuclear grenade, or even a nuclear bomb or something, I don't know if he will agree without principle......

"This is the latest research result of Professor Qian and Professor Zhu?" Wang Shunyi asked Liu Yijiu.

He didn't know much about that. But there are also some basic common sense.

Liu Yijiu nodded and didn't speak, who knows these things? Anyway, this body is really good, with such a rebellious teacher as a shield for him, otherwise, he would have to be arrested by Qian Lao and them to study as aliens.

The alien legends in this world have never been broken.

Many of the technologies of the American imperialists are said to have come from aliens, and they have not been declassified until their time.

However, many high-level US leaders have come forward to say some ambiguous things after retirement......

"Depleted uranium can greatly improve armor-piercing strength or armor resistance, and depleted uranium shells have a high-temperature cauterizing effect of 3,000 degrees Celsius after hitting the target......" Liu Yijiu just said this result, and did not say anything else.

Wang Shunyi thought it was because of confidentiality, so they didn't ask him anything more.

If that's the case, they'll have the project team at the very center of the base looking into this.

"How to make depleted uranium alloy, you tell me the test method and the effect that can be achieved, and I will arrange someone to do this. Although uranium-238 is not as radioactive as uranium-235, it is still relatively strong. Don't go get this...... "Wang Shunyi can't tell Liu Yijiu all the secrets in this base now.

"Could it be the research institute down there?" Liu Yijiu was immediately shocked.

He never knew why the base was called the Ninth Academy Base, and did it really have anything to do with the Ninth Academy that was engaged in nuclear weapons research?

The Republic researches nuclear weapons, but there is only that one, and there is no other semicolon!

But that unit does not belong to the Fifth Machine Department, nor does it belong to the Third Machine Department. Always independent!

"What is the base down there, isn't there a nuclear power plant inside our base? Naturally, there is a backup ...... technical and technical personnel in this area," Wang Shunyi hurriedly blocked Liu Yijiu's words. (To be continued~^~)

PS: Kowtow to thank Crazy Piggy 2 for his generosity of 100,000 coins. Originally, it was said that the alliance leader's fifth watch would be added on the second day, and it was estimated that it would not be possible to add seven watches tomorrow. Today, I hung up water twice in a row, my head was like a mess of paste, and I started writing it from before six o'clock, and it took me three hours to write this chapter, and tomorrow I can only look at my physical condition. If it works, the gourd will burst out in seven more, if not, it can only be divided into two times for a big change. Brothers, don't wait.,If you can code another chapter tonight.,It's going to be updated tomorrow.,But looking at the current situation.,It's really a bit hanging.。 Because Zhigong still has to update a chapter! Sorry brothers!
