Chapter 2352: High rate of fire

"Boom, boom, boom!" At the muzzle, with a huge roar, flames continued to emerge, and the flames rose one after another, as if the belly of a firefly flashed.
The black smoke rose from the muzzle, and it actually rose for tens of meters. It seemed that the rising mushroom cloud was called by death, and in front of the fire, the warheads flew out!
Even on land, I have never seen such violent artillery fire. When seeing the thick smoke from the muzzle rising over there, the captain here exclaimed: "Quick, full rudder on the left, snake-like maneuver! "
He was very afraid that his warship would be like the one just now. It was destroyed by the opponent’s gun. The warship just now has lost power and cannot move. Now his warship has sprinted and has enough power to proceed. Maneuvered to evade. However, just after he finished shouting, the deputy captain yelled loudly: "The shells will fall in front of us!"
An experienced soldier can judge the impact of the shells based on the sound of the shells flying over. Therefore, when the opponent's shells are flying over, he can’t run around. He was just staying and had to run around. The result happened to be in front of the cannonball. That should be the saddest situation, right?
The deputy captain has more experience, because before he boarded the ship, he had fought many battles on land before, and he heard the sound of howitzers fired more.
Turn left and turn right, snake-like maneuver, no good, what is the most important thing now?
"Two cars, reverse, full speed!" Hearing the words of the deputy captain, the captain finally gave an order to save them. The engine room at the tail promptly switched the propeller to the reverse position, and the warship began to slow down!
"Hum!" A huge cannonball fell in the water ten meters in front of their warship. When it hit the sea, it splashed a few meters high. Of course, the splash was still small. Then, I heard a terrible explosion!
The fuze was triggered, a huge explosion sounded, and the entire sea was overturned. The splash just a few meters high was just a small prelude. Then, below the surface of the water, an angry beast suddenly appeared. Generally, the sea is lifted up to a height of more than 30 meters, and the surging water column is as wide as a wall of water! It rose violently, and then turned down. The huge sea water seemed to hit the frigate like cavalry.
Wow!
The entire frigate was like a small sampan swaying in the waves. When this wave came down, everything that was not fixed on the deck was washed away. The entire frigate was washed by the sea. At this time, the underwater The explosion wave also hit the bottom of the ship, making a terrible sound. In this kind of impact, their frigates may burst!
This was just the movement of the first shell falling into the water, followed by the second and third!
One after another, the shells kept falling down! Each one will bring a baptism like a of death, and they landed right in front of every fleeing warship, forcing them to stop.
"Wow, this is too sturdy, right?" Looking at this scene, the foreigners on the scientific research ship felt one after another with emotion. They had never seen such a scene before. Only one old guy said thoughtfully: "It seems that I have returned to the peaceful ocean battlefield in that world war. Your naval gun is so powerful that it is incredible."
Of course, even if the previous naval gun was 406 mm, the main type of ammunition was armor-piercing bullets. When it fell on the water, it was just a few tons of iron that fell, and the splashes that hit it, although our caliber is 203 mm, but The grenade is used, and the scene after the explosion is definitely more spectacular.
Of course, some people also asked the most professional question: "Its rate of fire is too fast, right?"
That's right, this naval gun has many advantages. In addition to its power and range, there is one that makes people the most jaw-dropping, but only an insider can see it. It has a high rate of fire.
From a distance, you can only see the black smoke rising from the fleet over there. It is firing at a high speed. Just look at how fast the rate of fire is. Just look here. In less than a minute, it fell. There were dozens of shells. The shells did not hit any targets, but it was not that the accuracy was not enough. It was that there was no intention of hitting them at all. They were hitting the way in front of them. They were to be intercepted. Stop, then next time, I am afraid I will really greet them, die or surrender, you should choose one!
The high rate of fire of the naval gun is an even more sigh of it. Even the famous 76mm Otto naval gun in the West has such a high rate of fire, but it cannot shoot so continuously!
For naval guns, there are many reasons for restricting the rate of fire. The first one is the caliber. The larger the caliber, the slower the rate of fire, because the shells need to be loaded. The larger the shells, the harder it is to load, even the automatic loader. Exception, this is a basic common sense, but the main factor restricting the rate of fire of the artillery is not the caliber, but the cooling of the barrel!
This can be compared with the artillery system on the ground. For example, the land artillery with the highest rate of fire is the self-propelled artillery of the Hans people. Relying on the Hans people’s most sophisticated processing technology and the style of excellence, this artillery system is the best In the fast rapid fire mode, 10 shells can be fired continuously in 1 minute, which is already the world's first.
From the point of view of internal structure, naval guns and army howitzers are very similar. They were developed from the original cannon, but the actual rate of fire is very different. Needless to say, the current automatic loading system, even if it is ancient The manual loading of old naval guns has a rate of fire that exceeds that of howitzers of the same caliber.
Take, for example, the Type 61 100mm single-barreled naval gun equipped on the Luda-class of Han, which was developed on the basis of Xiong's B-34 type 100mm old naval gun. This old naval gun can reach a maximum rate of fire of 12 rounds per minute, which has surpassed the most advanced Hans.
So, what is the difference? Of course it is the heat dissipation system of the barrel.
The barrel life of the artillery is only a few seconds. For hundreds of shells, each shot is a ravaged by high temperature and high pressure for the barrel. If you hit it once, you will have a rest. It is easy to say that if you shoot continuously, it will make the barrel unbearable. This is not only the lower accuracy caused by thermal expansion and contraction, but also the risk of blasting.
