Chapter 116 Those who build naval guns cannot lose to those who build machine guns

 Qin Tao and Zhao Ling stood behind this group of people.

When Qin Tao said that sentence, Zhao Ling sighed in her heart. Qin Tao would never say anything casually. Since he said this, it means that this method is really feasible.

 The problems that have troubled these people for a long time may be easily solved by Qin Tao, just like the problem of the helicopter's landing assist system.

"Who are you?" Xia Bei looked at these two people in surprise.

"We came from Mingzhou Shipyard. I am Zhao Ling, the representative of the military stationed in the factory, and this is Qin Tao, the engineer in charge." Zhao Ling introduced: "The missile boats we are responsible for building need to install this kind of machine gun as a Main gun, so let’s come over to see the progress of the research, and this is our letter of introduction.”

 Zhao Ling? Qin Tao?

Xia Bei took the letter of introduction, glanced at it briefly, and then asked: "Is it the Qin Gong who helped the Navy solve the problem of the helicopter assist landing system?"

"it's me."

"Great, Gong Qin, my name is Xia Bei, and I am the person in charge of this gun." Xia Bei said quickly: "The accuracy of our gun is not high. Is it a problem with the electronic system?"

What Qin Tao did had been spread within the system. However, since he had never seen it before, he would not know much about it. Xia Bei thought Qin Tao was engaged in electronics, so he immediately asked. .

"There is no problem with the electronic system. Of course, Lao Maozi's system is analog. If you can replace it with a digital one, you will definitely be able to continue to improve the accuracy. However, this cannot be changed in a few clicks." Qin Thao said.

"Then what's the problem? You just said, put on airs, where do you put on airs?" Xia Bei asked.

“A suitable rack can be installed on the gun barrel according to the specific layout. The purpose is to control the vibration of the gun barrel.” Qin Tao said: “The problem of low accuracy is mainly caused by the vibration of the gun barrel.”

 The barrel vibrates?

 Everyone looked at the six gun barrels that were assembled together. The outside was wrapped with a layer of lightweight aluminum alloy. When the entire device fired, the flames at the muzzle were very spectacular.

 It’s just that no one noticed that this thing actually vibrates and affects the accuracy?

 “Then why didn’t Lao Maozi add it?” a technical staff asked.

"Lao Maozi has always been stupid and rough. They don't care about accuracy. If the accuracy is not enough to make up for the quantity, the worst thing is to install a few more." Qin Tao said: "We want to improve it. If we want to improve the accuracy, we have to find ways to overcome the flaws left by Lao Maozi. .”

“So, after improvement, can its accuracy exceed that of its brother units?” Someone asked again.

 Qin Tao's inner feeling is that only with competition can there be motivation!

In fact, the country has long attached importance to short-range defense systems. As a veteran naval gun design institute, the 713 Institute quickly proposed a six-barreled 37mm cannon plan. After all, they have ready-made double-barreled 37mm cannons on hand. Just six barrels are enough. This is their 637 naval gun.

 In addition to them, there is also Factory 847, which also manufactures cannons. However, they mainly manufacture aerial cannons for aircraft. Their product line includes 30mm cannons.

 So, they proposed a seven-tube 30mm close-range anti-missile gun plan, which is the 730 naval gun, specifically code-named PJ-12 short-range anti-missile naval gun weapon system.

In the early to mid-1980s, the Navy organized experts to analyze and demonstrate the 637 naval gun plan and the 730 naval gun plan. After a comprehensive evaluation, they decided to adopt the 730 naval gun plan. The project was established in July 1985, so it was also called Project 857.

The project of Institute 713 was canceled in this way. They were very dissatisfied that they, who were engaged in naval guns, had their project taken away by a unit engaged in aviation cannons! Now, they have been given the task of mapping the imitation AK630 naval gun. They are very excited and look forward to quickly producing this gun and equipping the troops.

Moreover, they have very high requirements for themselves, and they are trying to squeeze out the 730 project to take a breath.

Qin Tao is very clear about these histories, so he is very sad at this time.

"Don't talk nonsense, and pay attention to the confidentiality discipline." Xia Bei spoke.

Qin Tao smiled: "I don't know what the brother unit's project you are talking about is, but if the other party uses an external energy drive, it must have inherent advantages. In terms of accuracy, ours This product can’t be beat.”

In the mouths of many Erduodao, they will say that the 730 naval gun is copied from the AK630 naval gun. This is simply nonsense.

 Although they are both Gatling guns, the driving principles of the two guns are completely different.

The 630 naval gun is driven by a built-in energy source. Simply put, it uses its own gunpowder energy to drive the barrel to rotate after the naval gun is fired. The 730 naval gun is driven by an external energy source, and its barrel rotation is driven by other power devices (hydraulic, electric).

 The working principles and cyclic actions of the two are completely different and are incomparable. This is definitely not a matter of adding a barrel.

Also, what is the imitation of the Dutch goalkeeper? It may have been used as a reference, but it is definitely not copied. The ammunition supply system of the two is different. The 730 naval gun uses a chain-free drum feed method on the right side, and the bottom is empty. The goalkeeper system is similar to the AK630. Under it, there is a huge ammunition supply system.

 Schemes driven by internal and external energy sources have their own advantages and disadvantages.

Because the 630 is driven by a built-in energy source, it does not require additional power from the warship. It can rotate by itself, and it only takes 0.2 seconds to reach the maximum speed from startup. After all, it uses the power of gunpowder, which is very violent.

The 730 naval gun requires a sufficient power supply from the warship. Once the warship is attacked and the power is interrupted, it cannot be used.

 Furthermore, because a lot of things are missing, the cost of the former is lower.

  However, external energy is still the trend, because the 630 naval gun is driven by built-in energy, and the internal mechanism of the cannon is too complex, resulting in increased vibration, so the accuracy is poor.

To put it simply, the problem of low accuracy is brought out from the mother's womb.

 “Not comparable?” After hearing his words, everyone was a little discouraged.

"Yes, in terms of accuracy, it is definitely incomparable, but in terms of finalization time, our imitation will definitely be earlier, and in terms of production cost, our naval gun will be lower, so now we have the time advantage and Due to its cost advantage, this naval gun will definitely be equipped with a large number of navy."

 Everyone's eyes shone again. Xia Bei swallowed his saliva and said, "You said to add some airs, how to add it specifically?"

Qin Tao revealed the secret. In fact, all kinds of close-in defense guns in later generations would add a shelf in order to reduce the vibration of the barrel. However, because the shelf was considered from the beginning of the design, it has inherent advantages. Generally, the shelf is considered from the beginning of the design. It will be a stable multi-link frame, and even the part in contact with the barrel can extend to the vicinity of the muzzle. It's just like the frame set up around the saplings when planting trees.

Now this imitation of the AK630 naval gun is not so convenient, because the base behind the barrel is not large. At present, the only way is to simply add a tie rod, which is fixed on the turret at the back, and connected to the barrel through a bearing at the front. together.

As soon as Qin Tao explained his thoughts, everyone understood immediately.
