Chapter 133: Semi-automatic filling

In later generations, Han Guo chose a 125mm tank gun. When the finalization was successful, one of them was very embarrassing.

That is the 120mm tank gun developed by Han Guo!

Probably in December 1978, the development task of the 120mm high-pressure smoothbore gun as a new type of main battle tank and self-propelled anti-tank gun was officially issued by the Ministry of Machines and Armored Forces. At the end of the year, three high-pressure ballistic guns came out. The gun test was successful on February 19, 1979.

This progress is quite fast, as long as you look at the time at that time, it happens to be the time when the Hans Leopard-2 technology was introduced.

It can be said that the 120 guns at the time were almost a replica of Hans' Leopard-2 tank gun.

However, just as the development of the 120mm tank gun and its supporting ammunition was proceeding smoothly, the new tanks that matched it did not end in a hurry. The 120mm artillery project, which was about to enter the finalization of the design, was immediately suspended.

Seeing that this gun is about to die, the 4447 factory in charge of research and development at that time decided to install the 120 mm tank gun on the Type 321 chassis of the 83 type 152 mm self-propelled howitzer in order to preserve the results of the labor. Factory type testing of guns and armor-piercing shells.

So, in this way, the Type 89 self-propelled anti-tank gun was saved. At any rate, I kept the fire.

Tanks are mainly for charge and battle, and must have strong armor protection, strong firepower and maneuverability, but self-propelled anti-tank guns are unnecessary.

Its only use is to fight enemy tanks. Therefore, what it needs is fierce firepower. After the 120mm cannon is installed, it is more than enough to deal with the bear country in the north. It can even penetrate the bear country’s T- at two kilometers. 72's front main armor.

Its combat method is concealed standby, the first enemy discovers, and the first enemy fires. To put it bluntly, it is to hide secretly, shoot cold shots at the target, and kill the target in a short time.

Because there cannot be only one target, a sufficient rate of fire is a prerequisite for achieving the combat goal.

The design index of this anti-tank gun clearly states that the time from finding the target to completing the shooting is no more than 12 seconds, it can complete 3 rounds/20 seconds, 5 rounds/30 seconds, and the continuous rate of fire is not less than 6 to 8 rounds. /Minute.

At the same time, due to the design of the large munition chamber and the fixed loading projectile, the weight of the armor-piercing projectile and the grenade projectile can reach 23 to 30 kilograms. In order to solve the contradiction of the high rate of fire, an automatic loading mechanism must be equipped.

However, if a fully automatic loading machine is used, the difficulty will be greatly increased, which will eventually cause the project to abort. Based on the actual situation, the 4447 factory designed a tail cabin structure, fixed-point automatic bomb feeding, manual bomb retrieval and semi-automatic loading. machine.

If we can take this set of structure, we can effectively solve the problems we are facing now.

The 120mm shell is too heavy, and automatic reloading seems to be a good choice, so that all indicators of the T-72 can be suppressed.

However, automatic filling is too difficult. Semi-automatic filling will greatly reduce the difficulty, improve reliability, and suit your own industrial level.

Yes, that's it!

"I wish you old, this problem is handed over to our 4447 factory." Qin Guan said: "We spent a month or two to develop a semi-automatic filling system suitable for our new tank. What do you think?"

In addition to automatic and human flesh filling, there is another one called semi-automatic!

Qin Guan can’t figure out the specific principle yet, but to put it simply, the tail tank feeds the shells and automatically transports the shells, and then slides to the side of the loader. The loader does not need to turn around, find the shells, move the shells, and turn around After returning to these actions, the loader can squeeze the cannonball into the barrel with a push of his hand, which greatly reduces the labor intensity of the loader and reduces the risk. At the same time, the reliability is high.

Qin Guan said briefly, and sure enough, a spark appeared in Old Zhu’s eyes: "Qin Guan, you are simply a genius! Okay, the Ministry of Machine-Building 5 will issue an official notice soon. Factory 447 is responsible for the development of this Semi-automatic filling device."

The loader is still needed, but the loader can save a lot of effort and adapt to local conditions. This idea is great!

It's just that the military's tests and comparisons also take time. With this period of time, maybe Qin Guan can be developed. I don't have to doubt Qin Guan's ability at all.

After spending a day in the shooting range, Qin Guan was almost blackened by the sun, and his skin was extremely dry and cracked. At night, there was a dust storm outside.

"It smells good." After returning, Qin Guan smelled a scent: "This is Quanjude roast duck?"

"Yes." Chen Yutong said: "Today, sister Xiang Jing took me to Quanjude. The roast duck there is indeed a well-deserved reputation. We ate two and brought you one."

I have been in the capital for many days, but Qin Guan seems to have not visited the capital’s scenic spots, nor has he walked the streets and alleys of the capital to eat authentic street food.

"Well, it tastes good." Qin Guan didn't wash his hands either. He picked up a pie crust, put the roast duck on it, added some green onions and sauce, and then put it in his mouth and chewed.

The roast duck is oily but not greasy, the sauce is sweet, coupled with the spicyness of green onions, it mixes into a unique taste in your mouth.

"Well, it's delicious."

Qin Guan continued to take one piece. At this time, without Qin Guan's hands, Chen Yutong had wrapped it up for him and stuffed it in his mouth.

After eating five yuan in a row, Qin Guan finally had almost eaten it. At this time, Chen Yutong continued: "Also, sister Xiang Jing said that she may have other tasks and may not continue to follow us."

When she said this, Chen Yutong's black eyes looked at Qin Guan, wanting to see what the expression on Qin Guan's face was.

Would it be a pity? Do you want to stay? Still happy?

Xiang Jing is a member of the Vulture Troop, and it is impossible for Qin Guan to be a bodyguard forever. Now that he has a mission, he has gone out. That is normal.

Qin Guan didn't show any expression when he heard Chen Yutong's words. Yes, it didn't have any expression. Chen Yutong didn't give it to him, so he just grabbed it and started eating.

"Hey, Brother Qin Guan, I said Sister Xiang Jing is leaving, don't you have anything to say?" Chen Yutong yelled at Qin Guan.

"Xiang Jing, come out, is it interesting?" Qin Guan said, "You two, are you betting?"

Qin Guan's mouth was full of oil, and his speech was vague.

Want to lie to yourself, is it interesting? When I came in, I found Xiang Jing hiding in the cabinet. There were still slits in the cabinet. From there, I should be able to see his expression clearly.

Chen Yutong lied to herself that Xiang Jing was going to leave, and Xiang Jing depended on her attitude. This was a farce, so Qin Guan called Xiang Jing out without hesitation.

Did Xiang Jing forget that he has the ability to discover others?

Xiang Jing could only pouting her lips and got out of it. It was hard to imagine that she could actually put herself in such a small cabinet, as if she had practiced bone shrinking skills.

"Well, I gave up." Xiang Jing said: "Comrade Qin Guan, I can tell you a good news. I have officially transferred from my original unit to take up your personal protection task."

After that, Xiang Jing's face became very dark: "Now, let me and Yutong teach you together, and actually transferred me from my original unit, it's all you!"
