Rebirth of Military Workers

Chapter 313

It stands to reason that the shooting test of tank guns cannot be carried out in this way, and the most basic shooting test must be started step by step.

However, 404 does not have so much time to wait for the long test process.

In addition, 404 has the right to independently establish a project. In the experiment, even if it does not meet the rules, no one will say anything.

The military simply doesn’t care.

As long as the result.

Now, it is decided whether the entire project can complete the production of the prototype car in the originally expected time.

Who is not worried?

“Huh? Why are the Iranians here!” Seeing that the preparations were about to be completed, Xie Kai heard the sound of the car engine coming from behind and turned to look at the Iranians.

The Iraqis also spotted the Iranian who got off the car. Both sides spotted each other. No one spoke again, and their angry eyes wanted to kill each other.

“Damn, they are everywhere!” Ibrahim cursed in a low voice.

Ishad and others did not say anything.

The Iranians did not say anything to the Iraqis. After greeting Zheng Yucheng and others, they kept a distance from the Iraqis through Zheng Yucheng and others in the middle.

Both sides were tacitly approaching the tank gun mounted on the test bed in front.

“Chief, the shooting experiment is ready, please give instructions!” I don’t know whether it is the garrison regiment or the cadre of the base’s internal guard. After the tank guns and targets are ready, they report to Qin Jinyuan.

“Let’s get started.” Qin Jinyuan looked at Zheng Yucheng, who nodded, very nervous, but knew that he couldn’t delay it.

The ugly daughter-in-law will have to see her in-laws sooner or later, but the test is too relevant.

Both potential big customers are here.

“Didi…” The commander blew the whistle, and the small red flag in his hand began to wave. The soldiers guarding behind the tank gun started to reload by hand.

The huge 70mm long shell was held by the test-fired loader with both hands and stuffed into the barrel.

After the shell enters the chamber, the breech block is manually closed and locked, the loader retreats back, and the operator shakes the handle used to adjust the height of the muzzle, and starts to adjust the muzzle according to the design reported by the commander. Aim directly at the target board two kilometers away.

After aiming, after repeated inspections, he retreated to the back.

Although it is manually loaded, the tank gun is different from the howitzer in that the launcher does not require the use of people to pull the pilot iron to hit the bottom fire of the shell, but uses electric shock to fire the shell.

There are wires on the test platform that are connected to the operating platform that is transported more than ten meters behind. You only need to press the launch button at the back, and the shells in the barrel will fire.

The tank gun used in the test is mounted on the artillery support, behind which is an anti-recoil device composed of a retreat follower, and even an anti-dangerous plate used to protect the operator when the artillery fires. No one dared to ensure the test. The process was not unexpected.

“Isn’t there an automatic loading mechanism?” Ihor asked Wang Guilin next to him puzzledly.

“Now is to test the performance of tank guns and shells. The test needs to be done step by step!” Zheng Yucheng’s explanation was translated into Arabic and Persian. “At the same time, the automatic loading machine needs to be tested on the prototype vehicle. After all, the automatic loading of the tank is different from the manual loading used now. The fuze and the propellant of the shell are separated. Of course, such a test will definitely be carried out later!”

Automatic loading, this is determined from the beginning of the 359 tank.

Otherwise, the shells would not choose to be manufactured to a length of 0.7 meters.

The 359 tank was originally a modification of the 59 tank, and the chassis is not too restrictive and the space is naturally not too much.

Coupled with the T72 automatic loader technology obtained domestically, the length of the loader’s bomb bay is restricted, and any shell cannot exceed 0.7 meters.

The longer the shell, the more propellant that can be loaded, and the higher the muzzle velocity that can be provided.

In Germany and France, the length of the shell is about one meter, and it will naturally provide a higher initial velocity when it exits the chamber.

“The No. 1 gun position, the 2,000-meter 350 mm homogeneous armor No. 1 target plate, the No. 3 armor-piercing projectile, launch!”

Following the death of the commander, the launcher behind the ready-made No. 1 position pressed the launch button.

“boom!”

A ball of fire flashed at the thick muzzle, and then a huge roar sounded. The barrel retreated back as soon as the gun was ejected from the barrel. Under the action of the re-entry machine and the parking machine, even a large part of it was eliminated. With recoil, everyone standing more than 20 meters behind the gun position still felt a shock coming from the ground.

At this time, I didn’t care, everyone raised their telescopes and looked at the target at a distance of two kilometers.(Read more @ wuxiax.com)

This is the first shell of a 125mm tank gun.

Xie Kai also held a military binoculars, equipped with a speedometer on the muzzle, and even an air defense radar vehicle was turned on in the distance to measure the ejection velocity of the gun…

After the sharp armor-piercing projectile was out of the chamber, the outer projectile spread out towards the back, fell to the place, and flew at a high speed to a target two kilometers away at an invisible speed.

“Hey~”

The naked eye was unable to see the movement of the shells clearly, leaving only a stern and sharp sound of breaking through the air.

“boom!”

On the distant target, the armor-piercing projectile slammed into it.

“The tail wing stable shelling armor-piercing projectile?” Ihor, who knows the goods, asked inexplicably astonished Zheng Yucheng next to him.

Zheng Yucheng nodded, “I must test the armor-piercing projectile, isn’t it? This kind of charge is less. The full charge kill blasting grenade has a higher chamber pressure…”

According to the tank gun test plan, these tank guns will be gradually tested in accordance with armor-piercing shells, anti-personnel blasting shells, and armor-piercing shells.

The Iraqis are a little tempted on the side.

Especially for Isard, the stabilized tail wing armor-piercing projectile is the most advanced armor-piercing projectile, and they simply can’t get it.

As soon as the Chinese came up, they experimented with such shells in front of them, and the intention was naturally obvious.

“No. 2 gun position, 2000 meters 350 mm homogeneous armor No. 21 target plate, No. 3 armor-piercing projectile, launch!”

“boom!”

The muzzle flashed a fire that was larger than that of No. 1, and the entire barrel shook.

Everyone who was watching frowned.

Xie Kai’s heart even tightened.

The gun at No. 2 position has a muzzle brake!

Although the shells on the outside of the armor-piercing projectile separated after it was ejected, the sound of the armor-piercing projectile piercing the sky was far less sharp than the first one.

“Miss the target!” Long Yaohua said regretfully.

Yes, this armor-piercing projectile missed the target even when it aimed at the target.

The whole scene was banned for a while.

“Continue to test fire, the muzzle brake!” Qin Jinyuan had already prepared for this situation.

The muzzle brake has an effect on the stable shelling of the armor-piercing projectile of the rear wing. In fact, everyone knows that, but the muzzle brake can reduce the recoil by at least 40%. This performance is very attractive.

The tank gun of the 359 tank will adopt the best plan obtained after the firing test.

“Muzzle brake, is it really impossible to install this thing?” Xie Kai was a little speechless.

He knew better than anyone that none of the tank guns were equipped with muzzle brakes on the advanced main battle tanks behind them.

None of China’s 99, Lao Maozi’s T14, American Emperor’s M1 series, German Leopard 2 and other tank guns are equipped with brakes.

The reason why Xie Kai didn’t stop this plan is because China has just acquired the technology of stabilizing the tail wing armor-piercing projectile, and it doesn’t know enough about it. The muzzle brake is too strong for the weakening of recoil. This makes it necessary to conduct such tests.

Even make improvements.

Once the expectations are reached, the chamber pressure of the tank gun will be further increased.

Neither the Iraqis nor the Iranians have expressed anything.

The experimenters at the base were somewhat nervous.

But the three guns behind are still starting the firing of the first gun.

Another tank gun equipped with a different muzzle brake did not miss the target, but in the final result it did not penetrate the 350 mm homogeneous armor target!

“Record the data and continue loading!” After Qin Jinyuan asked Zheng Yucheng and others, he was instructed to continue the test firing.

It is still an armor-piercing projectile, but the thickness of the uniform armor has begun to increase.

Each target is increased in thickness of 50 mm.

It has been unable to penetrate, and then re-manufactured the target for experimentation.

“boom!”

“boom!”

In order to obtain more data for the newly developed 125mm tank gun, the base test firing did not use the steel plate to tilt some angles to make theoretical predictions. Instead, a whole piece of thick steel was installed on the base below for more accuracy. The data.

Up to 500 mm of homogeneous armor, the three tank guns without muzzle brakes are all penetrating.

By 550 mm, it can no longer penetrate completely.

“Replace the composite armor target!”

There are enough targets prepared before, and the live ammunition firing test begins, and the gun will be fired until the entire barrel has problems.

“Director Zheng, it won’t work today. The cannon must be pulled back for testing. There is no problem to proceed…” After a few shots, Qin Jinyuan did not dare to be careless.

Zheng Yucheng didn’t force it either.

Compared with the 105mm rifled gun can only penetrate the homogeneous armor of 350mm thickness, the armor penetration capability of the 125mm tank gun has been greatly improved.

“Computer simulation analysis shows that if the length of 52 times the diameter of the barrel is used, how much will the armor penetration ability increase?” Xie Kai asked.

“This is already very good!” Qin Jinyuan looked at Xie Kai, and didn’t understand what he meant.

How did he know that Xie Kai was not satisfied with the armor penetration thickness of just over 500 mm of uniform armor?

The 125mm tank gun on the 99A has a piercing thickness of more than 1000mm!

“We still have a lot of potential to tap. Whether it is the material of the armor-piercing projectile, the barrel of the artillery, the charge of the projectile, etc., it can be effectively improved…” Wang Guilin comforted Xie Kai, “Compared with domestic tank guns. , This performance is already very good.”

“Our gun adopts all the new crafts and technologies, and the potential that can be tapped is not much!” Xie Kai knew very well that this kind of offensive power would not allow the Iraqis to overthrow the American imperialism in the Gulf War. The M1 main battle tank is at best bullying the American M60.
