Chapter 117: Accuracy improved by an order of magnitude
Although Qin Tao has not taken it apart and looked at it, Qin Tao also knows it. Now that he explains it to Zhao Ling, everyone else can't help but give a thumbs up. Qin Tao is really awesome and knows everything.
Qin Tao continued: "However, the shape of this shell is not good-looking. I will design a new turret shape for you later. It is not only beautiful, but also can match the shape of our missile boats."
What matching shape does a missile boat have? Of course it’s stealth!
The stealth of this round turret still needs to be improved. Of course, Qin Tao only cares about the design. As for what materials to use, whether to continue to use plastic or aluminum alloy, it is not Qin Tao's consideration.
"New shell?" Xia Bei was a little curious.
"Yes, the new casing. The products you provide us must use this new casing. Otherwise, our military representative will not sign." Qin Tao said.
I just happened to bring Zhao Ling here, and now I can use the tiger skin to make a big flag.
Zhao Ling could only nod. The matter of a shell was not a big deal. Since Qin Tao insisted, let him do it.
"All right."
After taking apart the shell, you can find that the entire second half of the barrel is hidden inside the turret, and only part of it is exposed outside. This additional bracket starts from the tail fixed point of the turret and goes forward.
Extends all the way to the outside and is connected to the barrel through a special bearing.
In this way, it is equivalent to adding an extra fixed rod on the outside, and it can also perform pitching and rotation along with the gun barrel without affecting the aiming of the target.
"No need to install the shell, test again!" Xia Bei continued to shout.
Testing missions soon resumed.
This kind of artillery can use radar for fully automatic aiming and shooting, or it can be manually controlled using an optical system. It is currently only a test gun, so it uses manual aiming. The test gunner used a replica SP521 electro-optical tracker to aim at the target.
, and then pressed the button again.
boom!
The barrel rotated rapidly, and a ball of flame shot out from the muzzle, just like a flamethrower. Just in front of the flame, countless dense shells flew out.
Zhao Ling opened her eyes wide: "How many shells can fly out at once?"
"It takes 0.2 seconds to reach the maximum firing rate from startup." Qin Tao said at the side: "Its maximum firing speed, the initial model is 3,000 rounds per minute, and the later model is 5,000 rounds per minute, which is equivalent to
It can fire more than eighty rounds per second."
"Qin Gong, you are very familiar with this gun." Xia Bei said.
"Just so so." Qin Tao was very modest.
While talking, the shooting has ended. This kind of gun fires in short bursts. Although it is said that there are thousands of rounds per minute, its ammunition reserve is only one or two thousand rounds. (Various data give different data.
Some say to prepare a thousand rounds of ammunition, and some say to prepare two thousand rounds of ammunition, but it is much higher than the 500 rounds of ammunition of the 730.)
"Isn't this too outrageous?"
"What's wrong with this? The Americans' Phalanx has a rate of fire of tens of thousands of rounds." Qin Tao said.
"Actually, if we want to achieve a rate of fire of tens of thousands of rounds, there is a way." Xia Bei said: "We have already studied it. The ammunition preparation of this system is from the left, and the right is empty, so,
If we superimpose another gun barrel on top of it and provide ammunition from the right side, the two guns can fire at the same time to achieve a rate of fire of tens of thousands of rounds."
The military workers of this era are smart enough! They can actually think of this!
After the collapse of the Soviet Union, Lao Maozi had no choice but to rest on his laurels. Although they developed an integrated artillery and artillery system, they continued to upgrade their AK-630.
The new model is AK-630M1-2. In addition to improving the turret to a stealth shape, it also places two groups of 6-barreled 30mm cannons up and down, with a total of 12 barrels. The rate of fire per minute is increased to 10,000 rounds.
, the firepower is definitely brutal enough.
Qin Tao nodded: "Yes, Mr. Xia, what you are talking about is an improvement idea, but..."
"However, the problem of barrel jitter will be more prominent, and the dispersion accuracy will be worse." Xia Bei was very smart, and then he thought of this drawback.
"Yes, that's the problem. However, if you change the perspective, this problem of poor dispersion accuracy actually becomes an advantage. A large number of artillery shells can form a wider interception surface, which is more effective against small targets that penetrate defenses at low altitudes.
You have to try it to know the specific effect."
It's similar to the multiple rocket launcher, but the accuracy is poor? It's not a problem. Let's fire a batch more, and it will become a weapon with an area of destruction.
Of course, Qin Tao doesn't know the specific interception effect. Which one is more effective, whether to deploy two cannons to intercept together or a double six-barreled cannon to intercept.
Practice brings true knowledge, let’s talk about this later.
"The data is out, and the dispersion accuracy has improved by an order of magnitude! In the past, half of our shells would fly away, but now, all the shells fall on the target!" The person responsible for checking the target ran back and shouted excitedly.
"Well, it really works." Xia Bei's eyes lit up: "In this way, we can also do business! Qin Gong, thank you very much, the idea you gave us is really good!"
Qin Tao nodded: "Well, since the test is OK, you hurry up and build the cannon. We are still waiting for the installation! Come on, I will draw the design drawing of the turret for you!"
Zhao Ling followed behind and sighed for a while. Qin Tao was so awesome. He could solve the problem with a simple idea. There was nothing he couldn't do.
"Well, Gong Qin, if you want to continue to improve the accuracy, is there any other way?" Xia Bei continued. He has always been worried about improving the accuracy because they have to compare with the 730 guns of their brother units.
Qin Tao frowned, thought for a moment, and then said: "The only simple way is to improve the accuracy of the manufacturing of cannonballs and barrels."
It is not easy to improve again. Strictly control the quality and improve the processing accuracy of the barrel and shells. Maybe the shells can be fired more accurately.
In the drawing room of the design institute, Qin Tao picked up a drawing pen and a drawing ruler, and quickly drew the polygonal turret shape.
Looking at the three views of this turret, Xia Bei was a little curious: "Qin Gong, why do you do this?"
"Stealth." Qin Tao said: "In the future, the stealth of warships will be an important indicator. Not to mention this kind of close-in defense gun, even the turret of the main gun will have to be shaped like this in the future."
"Stealth? Is it necessary to have stealth on such a large warship?" Xia Bei was puzzled.
"Yes, you can turn large warships into small warships, and the displacement of three thousand tons can be turned into one thousand tons." Qin Tao said: "This is the trend and trend. Let's wait and see in the future!"
