Chapter 116 Naval gun builders cannot lose to machine gun builders

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

  When Qin Tao said that sentence, Zhao Ling felt emotional for a while. Qin Tao would never say anything casually. Since he said that, 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 landing aid system.

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

"We came from the Mingzhou Shipyard. I am Zhao Ling, the representative of the garrison army, and this is Qin Tao, the engineer in charge." Zhao Ling introduced: "The missile boat we are responsible for building needs to install this kind of cannon as a Main gun, so, let's come over to see the progress of the research, this is our letter of introduction."

  Zhao Ling? Qin Tao?

  Xia Bei received 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 landing aid system?"

"it's me."

   "Great, Qin Gong, my name is Xia Bei, and I'm 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 has already been spread in the system, but, after all, he has never seen it before, so he won't understand it too deeply. 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, the accuracy will continue to improve. However, this cannot be changed in a few clicks." Qin Tao said.

   "Then where is the problem? You just said, put on airs, where did you put on airs?" Xia Bei asked.

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

  Gun barrel vibration?

  Everyone looked at the six combined gun barrels, which were wrapped with a layer of lightweight aluminum alloy. When the whole device was fired, the flames at the muzzle were very spectacular.

   It’s just that everyone didn’t notice that this thing vibrates and affects the accuracy?

   "Then why didn't the old man add it?" A technician asked.

"Old Maozi has always been stupid, they don't care about the accuracy, the precision is not enough to make up the quantity, the worst is to install a few more." Qin Tao said: "If we want to improve it, if we want to improve the accuracy, we have to find a way to overcome the defects left by the old Maozi .”

   "So, after it is improved, can its accuracy surpass that of its brother units?" Someone asked again.

  Qin Tao felt in his heart that only with competition can he be motivated!

In fact, the country has long paid attention to the short-range defense system. As a veteran naval gun design institute, the 713 Institute quickly proposed a plan for six 37mm guns. After all, they have ready-made double-barreled 37mm guns on hand. It's enough to go to six barrels. This is their 637 naval gun.

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

  So, they proposed a 7-tube 30mm close-in anti-missile gun, which is the 730 naval gun, and the specific code is PJ-12 short-range anti-missile naval gun weapon system.

In the early and mid-1980s, naval organization experts analyzed and demonstrated the 637 naval gun plan and the 730 naval gun plan. After a comprehensive evaluation, they decided to adopt the 730 naval gun plan. At that time, the project was established in July 1985, so it was also called Project 857.

  The project of Institute 713 was dismissed in this way. They were very dissatisfied. They were a naval gunner, but they were robbed of the project by an aircraft gunnery unit! Now, they have been given the task of surveying and mapping the imitation AK630 naval gun. They are very excited and look forward to quickly producing this gun and equipping the troops.

   Also, they're demanding of themselves, and they're trying to squeeze that 730 project out of the way.

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

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

Qin Tao smiled: "I don't know what the project of the brother unit you are talking about is, but if the other party uses an external energy drive, it must have an inherent advantage. In terms of accuracy, our There is absolutely no comparison to this product.”

  In the mouths of many Erdaodao, they will say that the 730 naval gun is imitated from the AK630 naval gun, which 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 built-in energy. Simply put, after the naval gun is fired, its own gunpowder energy drives the barrel to rotate. The 730 naval gun is driven by an external energy source, and its barrel is rotated by other power devices (hydraulic, electric).

  The working principles and cyclic actions of the two are completely different, and there is no comparison. This is definitely not a matter of adding a barrel.

   There is also a saying that it imitates the goalkeeper of the Netherlands. It may have been used for reference, but it is definitely not copied. The ammunition feeding system of the two is different. The 730 naval gun uses the right drum without chain feeding method, and the bottom is empty. The goalkeeper system is similar to the AK630. Under it, there is a huge bomb supply system.

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

  630 is driven by built-in energy, so it can rotate itself without the need for additional power provided by the warship, and it takes only 0.2 seconds from the start to the maximum speed. After all, it uses the power of gunpowder, which is very violent.

  The 730 naval gun needs the warship to provide sufficient power supply. Once the warship is attacked and the power is interrupted, it cannot be used.

   Moreover, 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 complicated, resulting in increased vibration, so the accuracy is poorer.

   To put it simply, the problem of low precision is brought out from the womb.

   "Not as good?" Hearing his words, everyone was a little discouraged.

"Yes, in terms of accuracy, it is definitely not comparable, but in terms of finalization time, our imitation product will definitely be earlier, and in terms of production costs, our naval gun will be lower, so now we have the advantage of time and Due to the cost advantage, this naval gun will definitely be equipped with the navy in large quantities."

  Everyone's eyes lit up again, Xia Bei swallowed and said, "You're talking about adding airs, how should I add it?"

Qin Tao made it clear. In fact, in order to reduce the vibration of the barrel, all kinds of near-defense guns in later generations will add a shelf. However, because the shelf has been considered from the beginning of the design, it has inherent advantages. 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 like the frame that was erected around the young saplings when planting trees.

Now this imitation of the AK630 naval gun is not so convenient, because the base behind the gun barrel is not big, at present, we can only simply add a pull rod, the rear is fixed on the turret, and the front is connected to the gun barrel through bearings together.

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