Rebirth of Military Workers

Chapter 312

“Aren’t we using the latest type of composite armor? The defense is high, and the enemy’s guns can easily kill our tanks?” Zheng Yucheng asked Xie Kai with wide-eyed eyes.

For a while, Xie Kai and Qin Jinyuan both looked at each other and smiled bitterly. How did they answer?

Using his spear to attack the other’s shield, what is the answer, who knows?

“Okay, the Iraqis are waiting. The specifics are still to be known after the gun is tested. The gun was dragged out in this way and went to the gun yard for shooting. How thick is the uniform armor that our gun can penetrate, and how can it hit? How thick the composite armor is to wear, there will be a conclusion over there.” Xie Kai sighed.

No matter how ugly the gun is, it is impossible to mount a tank turret when it is fired.

Especially the base below is fixed.

I’m afraid that this thing will not be able to resist it. Don’t have too much recoil and the base will not be able to bear it.

The Iraqis waited to see the sample guns for test firing, and had no other preparations, so they just dragged the sample guns into the gun yard for test firing.

The composite armor model of the base has been developed for a long time, and various tests have been carried out these days. Theoretical analysis has not tested which kind of composite armor has higher defensive power.

What is the penetration power of the 105mm rifled gun at the same distance? The initial velocity of the 125mm tank gun’s high-explosive shells, armor-piercing shells, armor-piercing shells, full-charge anti-blasting grenades and reduced-charge anti-blasting grenades must be tested. To be sure.

According to the previous plan, once the live ammunition test is launched, it will continue.

Up to now, a total of 5 sample guns have been delivered to the 541 tank base. According to the experimental plan, each sample gun must be fired with different shells until the barrel is scrapped.

For each shell, the initial velocity of the chamber must be measured, the chamber pressure in different states of charge, and the ability of the barrel to withstand the chamber pressure in different states.

After obtaining these data, special improvements can be made. Whether the material is further improved, whether there is a problem with the processing technology that needs to be improved, or the internal processing accuracy of the barrel, etc., need to be analyzed.

The 125mm tank gun produced five sample guns, none of which has been fired yet.

Even the 120mm tank gun of the original WZ-122 tank project ended up being just more than a hundred guns.

At the beginning, the test shot had to be ended because of material problems and processing technology problems.

Now no one can guarantee that new gun casting techniques such as new tank gun steel, barrel self-tightening technology, electroslag remelting technology, etc. are used, and even the chromium plating process and processing technology inside the barrel are also available. The introduction of technology exists.

No one can guarantee how far it will be.

“Do you need a long time to prepare?” The Iraqis were a little dissatisfied with Zheng Yucheng and Xie Kai communicating with the artillery experts of Project 359.

They are worried that the 404 people cheated them.

“General, we are to understand the actual situation. We have been conducting extreme environmental tests before. The combat performance of a tank is mainly the attacking ability of the tank gun! The best defense is offense. No matter how thick defensive armor is, there is no strong Its offensive power will eventually be destroyed by a siege of a bunch of tanks with poor performance. The Tiger and King Tiger tanks that Germany made the Allies terrorize in the past were eventually besieged by the Soviet T34 tanks? Ishad asked, who questioned.

The Iraqis knew about Soviet weapons and equipment.

The Soviet Union’s thinking on army building even affected Iraq. Otherwise, Saddam would not order more than 2,000 Type 69 main battle tanks from China.

Quantity is far better than quality.

The Soviet army was able to bring down the German army, which overturned the whole of Europe, by relying on its numbers.

Whether it is the number of troops or the number of weapons and equipment.

“This is indeed the case.” Isard had to admit.

“We don’t need to prepare. Both the shells used for shooting experiments and the homogeneous armor used to test the penetration are all ready. Not only need to experiment with tank guns, but also to test the defensive capabilities of composite armor!” Qin Jin Yuan said to the Iraqis.(Read more @ wuxiax.com)

He is from base 541, not the original personnel of 404.

The Iraqis are noncommittal. There is nothing to argue about in this matter.

If the Chinese want them to see their offensive power and defensive power, they naturally need to experiment.

“Just drag the tank gun to the shooting range?” Seeing that the Chinese had installed a flatbed cart directly under the tank gun, the Iraqis were a little confused, “Don’t you need to install it on the tank for experiment?”

“General, there is no suitable tank in our country that can withstand the recoil of a 125mm tank gun firing a full-charged shell! The 359 tank uses new technology and new materials to solve the problem of recoil.” Xie Kai explained.

In theory, there is no problem with tank guns.

All five sample guns were pulled out for experiments.

Some guns are equipped with muzzle brakes, and some are not.

“There are not many countries with muzzle brakes installed on tank guns?” Harry Mossant asked Xie Kai. He clearly saw that two guns were equipped with muzzle brakes. “Muzzle system Although the retractor can absorb a large part of the recoil, it will also cause a lot of difficulties and affect the shooting accuracy…”

“It’s true, and it will even affect the separation of the stabilized tail fin shelling armor-piercing projectile from the shrapnel…” Qin Jinyuan nodded, “Our current gun has not yet finalized its shape. Experiments are needed to obtain various parameters!”

In order to obtain more parameters, almost every gun has some subtle differences.

During the previous extreme temperature experiment, a large amount of data was obtained. These data are slightly different from the modification of the 125mm tank gun, especially the aluminum alloy air sandwich thermal jacket installed in the middle of the barrel. , The technology used on almost advanced tanks, and the 125mm tank gun produced by 541 to help 404 base can see shadows on it.

When Xie Kai started working on this project, he persuaded Mr. Zhu Yusheng to get technical support for the domestic third-generation tank project. The technology of these artillery also paved the way for the domestic third-generation tank project.

Five guns were transported by Jiefang Automobile and pulled to the gun field originally used for weapon testing.

On the way out, I ran into a construction site where an airport was being built. Dozens of military excavators with 59 chassis flattened a large area of ​​the valley floor that was originally not flat.

“These military excavators shouldn’t be delivered to the hydropower troops and the Iraqis?” Xie Kai looked at the dozens of excavators busy on the construction site, and asked Zheng Yucheng incomprehensibly.

“For the Armed Police and Hydropower Unit, our infrastructure will be handed over to them for construction. At the same time, their personnel will be trained on our side…” Wang Guilin explained.

Xie Kai rarely pays attention to these things.

The construction of the airport has been underway for so long, and he hasn’t come here to look at it, and he has nothing to look at. Everywhere is bald.

When Wang Guilin was talking about training, Xie Kai suddenly had a glimmer of light in his mind. He wanted to catch it, but couldn’t catch it at all.

“What do you want? This kind of cooperation is beneficial to both of us. After all, what is the current performance of our excavators and requires a lot of use to draw conclusions.” Wang Guilin thought Xie Kai was worried about the relationship with the customer.

404’s airport construction was all contracted out.

The engineering regiment in the base had already been evacuated as early as the evacuations of various projects.

“This is pretty good. If you have any problems, you can find out during use.” Xie Kai nodded and said.

Nothing was said, but instead of testing the 125mm tank gun.

For Xie Kai, the effect achieved by this gun test has seriously affected the progress of the entire tank project.

Any tank is often evaluated in terms of firepower, defensive capabilities, maneuverability and the technologies used above.

Test firing means whether the tank gun can be shaped or not. Once the theoretical design data cannot be reached, the five sample guns are just test items and need to be improved.

As a result, it will seriously affect the progress of the entire project.

“Are you worried about the experimental data of the tank gun?” Zheng Yucheng asked Xie Kai in a low voice while looking at the tank gun that was dragged by the Jiefang car.

Xie Kai nodded.

“Don’t worry, there is no problem. From the very beginning, our design has used supercomputers for finite element analysis. So far, all experimental parameters have exceeded theoretical data.” Qin Jinyuan comforted Xie Kai.

He himself was equally nervous.

In the 541 base, they had been idle because of the lack of projects after the 541 base was converted to civilians. With the 541 tank gun business, the entire 541 base artillery research team became busy again.

The schemes are all designed in accordance with the design provided by 404, and a lot of analysis has been carried out. The tank gun-related technology that has just been introduced abroad is used.

“The offensive ability of tank guns is not only guns, but also artillery shells.” Xie Kai murmured.

The Iraqis participated in the entire experiment.

After the tank guns were transported to the test range, they did not directly start shooting experiments, but used engineering vehicles to hoist these tank guns to a specially prepared location for installation.

The 125mm tank gun, when the gun is fired, produces a huge recoil, if it is not fixed, it will make the whole gun jump up.

“The artillery is a brand new sample, and the shells are also newly produced!” Xie Kai didn’t worry, it was fake.

There is no artillery of the same type in China. The shells of tank guns were also urgently developed by the technical team of 541 and 404. Of course, the main source of technology is the 105mm rifled gun ammunition that the British sold to China. .

The installation work proceeded very quickly. Several types of shells were placed not far behind the tank guns. From two kilometers to four kilometers, different types of targets were placed, and most of them were of different thickness. The homogeneous armor.

Most of these targets have been installed before.

Xie Kai looked at the target in the distance, and his thoughts were very complicated.
