Super military empire

The discussion continued until other people went to work. These designers who hadn't slept all night washed their faces and then went back to their posts.

For them, it is normal for them not to rest after staying up late and continue to work in this mountain.

As the saying in the quotation says: Ten thousand years is too long, just seize the day!

The republic finally ended the turmoil, and they finally had the opportunity to apply what they had learned in their life to contribute to the national defense cause of the motherland, and naturally they had to find the lost time.This group of people is like this. They can give up everything for the country.

All because they hope to have a strong motherland, and hope that under the protection of the motherland's powerful national defense forces, they will no longer be bullied by foreign powers!

From 1840 when the British giant ship artillery bombed the country gate of the corrupt Manchu Qing government, to the founding of New China, a total of 109 years, the entire land of China was in turmoil, and many patriots wanted to develop the defense industry. , But without the support of the state, everything was in vain in the end. The country is still weak. A small island country can bring serious disasters to Yangyang China for more than ten years!

All this is because the country does not have a strong national defense industry.

At present, the country strongly supports the development of the cutting-edge defense industry, and they naturally cannot give up such an opportunity.

As long as tanks are made, the pressure on the northern border will be much reduced.Because the tanks of the Republic are worse than the tanks of the Soviet Union by a whole generation, the number is even more insufficient!Once the Soviets begin their offensive, their steel torrent will be easily crushed to the capital of the Republic!

Liu Yijiu is the same, discussing in the evening, although the body is very exhausted, the mental state is not too bad.

The modification plan of the 59th tank has been completely finalized, and there is no need to do technical demonstrations. They have independently established these projects and can completely avoid this.Of course, if it were not for Liu Yijiu's confidence in realizing these above technologies, he would not fail to make technical demonstrations.

Otherwise, waiting for the tank prototype to be manufactured in the future, it will fall apart after a shot, and the joke will be a big deal.

Unscrew the faucet in the washbasin outside the office of District 9 and wash his face indiscriminately with clean water in his hand. The whole person has a lot of energy. Liu Yijiu went to the tank with Yu Mingjiang, the tired-looking fire control system design manager Inside the production workshop of the gun research.

Since last year, we have been working on upgrading the 100mm tank gun of the 59 tank to a 105mm rifled gun.

Regardless of the fact that the caliber has only increased by five millimeters, for a republic with a weak foundation, the difficulties are definitely not small.What's more, the development of a 120 mm 50-caliber barrel was also launched here.

The 50-caliber tank gun of the 120 smoothbore gun is mainly composed of a smoothbore barrel, a horizontal wedge breech tail and a breech block, a barrel cradle, a control lever anti-recoil device, and a barrel thermal sheath.The artillery weighs 2600 kg.Its structure is simple and compact, reliable in work, and easy to use and operate.In order to speed up the work, Liu Yijiu stayed up late and drew these drawings after the new gun steel that Liu Yijiu provided the production process and raw material formula was manufactured on a small scale.

He has studied these, and he has a deep memory of drawings.

Of course, there are some non-critical places, he often does not pay too much attention, which requires researchers to support...

Originally, most people in the base tend to use 125mm smoothbore guns. After all, the Soviet standard has always been adopted in China. Now they have t64 and t72 in their hands. They are all 125mm smoothbore guns, so naturally they tend to This program is out.

Liu Yijiu knew that the Republic was about to introduce 105mm rifled guns in the United Kingdom, so when the world began to use smoothbore guns, he had to waste money and his own energy to get this out.In the whole world, for many years to come, only British tanks will be equipped with 105 rifled guns.How many tanks does the entire British country have?The entire NATO standard is a 120mm smoothbore gun. To export to NATO countries, the ammunition of the tank gun must be universal!The Warsaw Pact countries are too poor.

The power of 125 is not much greater than 120.

The smoothbore gun that the Republic imported from abroad in the mid-1990s was able to penetrate most of the third-generation tanks equipped by countries around the world within a range of 2000 meters!But Liu Yijiu appeared, so Leopard 2, m1a2, which could not be penetrated, was impossible!

The shape of the 120mm tank gun produced by the Ninth Institute is similar to the Type 59 100mm tank gun and the Type 83 105mm tank gun (this thing is imported from the UK) that will only appear in a few years, and the quality is similar to that of the turret. The interface size of other parts is the same, but with greater power!

"Director Liu, President Yu, didn't you sleep last night?" Chen Yang, a tank gun designer who was playing with a group of technicians with a model gun made of wood, asked in surprise when he saw the dissatisfied bloodshot eyes of the two."The body is the capital of revolution and life!"

"It's okay. Last night, I mainly discussed the assembly design plan of the May 9th Reform Project. How about you here? Haven't you started the sample trial production?" Liu Yijiu nodded and said indifferently.

"Now we are starting to prepare materials, Director Liu, there is really no problem with these design schemes? Especially the gun barrel self-tightening process, we have never touched it. The caliber has increased by 20 mm, and the weight has not increased. We always There is no bottom..." Chen Yang said with a wry smile.

The whole gun adopts a brand-new design concept, and even the self-tightening of the gun body adopts a process they have just heard of. Without more demonstration, Liu Yijiu asked them to supplement the design of some non-critical parts. , Just let it go into production and make the production process of sample cannon...

This kind of thing is really scary.

"No problem. You have been working on this wood model for a long time, and all kinds of data are constantly being simulated and calculated? You don't even believe the calculated data, do you? You are suspicious of technology research and development. Spirit, this is necessary, but you have to experiment boldly..." Liu Yijiu looked at the wooden model, feeling a little depressed.

There is no advanced computer and no matching 3D simulation software. If you want to analyze the structure from the overall design and perform various strength calculations, you can only use wood to make the model...

"What's more, this is not produced and will be used directly, there must be various experiments and tests!" Liu Yijiu's words gave Chen Yang and others a bottom.

They all knew about Liu Yijiu's miracle. As he said, there were real problems, and they would solve them at the end of the experiment.If you do not produce samples, you will never be able to find the problem, and it is even more impossible to discuss any improvement plan.

"It's going to cost money!" Yu Yang said with a bit of heartache, all from the difficult years.

Experiments in the Republic have never been wasted many times.

This is a miracle in the whole world.Just because the Republic is poor!

Dongfeng 2, only failed once, it succeeded!

"Money is not a problem! You only need to be responsible for all kinds of technical research. If you can't save it, you can't save it!" Liu Yijiu emphasized again.

The Republic’s attitude of diligence and frugality has made technology research and development very conservative. Many designs use mature technologies and design solutions, which will eventually cause greater waste.It also limits the designer's thinking.

Zhi-7 is the best example.

Now Liu Yijiu must correct this problem from the beginning. The money that should be wasted cannot be saved!Otherwise it will cause greater waste.

Only by failing can we achieve greater success.

The Soviets invested heavily in weapon development, and the Americans were even more embarrassed. Basically all kinds of weapons were piled up with money.Therefore, their weapons and equipment are developing very fast.The Republic did not realize this problem until the second decade of the 21st century, with money on hand, and devoting much money to weapons, equipment and technology.

"Is it unnecessary for us to get the 105 guns? It's a waste to get two guns at the same time..." They didn't consider the funding of the base, but the province's must be saved.

Therefore, Yu Mingjiang also felt that it was another 105 cannon, another 120 cannon, and even a third 125 cannon design...

The caliber is the same, and the power is almost the same, it is really unnecessary.

"No, you have to do it! The rifled gun and the smooth-bore gun are two different types of guns. If our 105 rifled gun can reach the power of a naval gun, wouldn't it allow our tanks to have more powerful attack power?" Although Liu Yijiu knew that the artillery's attack range was basically two kilometers away, but in order to save the country a foreign exchange for importing such artillery from Britain, he had to make it out.

Even if it is not useful, it is good to be used as a technical reserve.

Although his reasons were far-fetched, Yu Mingjiang did not say anything.

This is how the plan was made at the beginning. The new tank project temporarily named as the “59th Reform” will produce two prototypes, one with 105 rifled guns, one with 120 smoothbore guns, and possibly even 125 smoothbore guns. After all, considering the war with the Soviet Union on the northern border, you can use captured ammunition to supplement...

"The chromium plating process inside the barrel needs to be studied carefully. This can effectively improve the stability of the ballistic performance of the artillery during the barrel life, so that the artillery will always maintain the same ballistic performance and shooting accuracy before the end of the barrel life. No change... The inner barrel of the barrel is chrome-plated, which is also convenient for maintenance and improves the anti-corrosion performance..." Liu Yijiu didn't understand the chrome-plating technology inside the barrel. Anyway, just explain it.

At that time, there will naturally be surface treatment technicians from the second district to cooperate.
