Chapter 264: The Consequences of Not Closing the Door
Although much larger than the Yoshino, the defensive cruiser's design flaw in placing the coal bunkers on both sides of the dome armor was common, so the silver explosives, which had a strong arson ability, caught fire immediately on the side of the board. Pen & Fun & Pavilion www.biquge.info And because of a design that was originally very praiseworthy, the situation was worse than those hapless Japanese defense patrols at the beginning......
Unlike export-oriented warships, which pay more attention to the performance parameters on paper (which is easier to sell), Britain's own warships pay more attention to "hidden attributes" such as reliability and sinking resistance.
For example, in order to enhance protection, the position of the coal bunker is relatively high, and the advantage of this is that almost all parts of the side that may be hit by enemy shells have the additional protection of the coal bunker; As for the lower part below the waterline, due to the close distance of the battle at that time and the straight trajectory of the artillery, it was impossible for the shells to hit, and the torpedoes and mines were certain to die, so there was no substantial loss without the additional "armor" of the coal bunker.
But once the coal bunker caught fire, an unexpected problem was suddenly exposed, how to fill the coal bunker with such a high position! The reason why it is called irrigation is naturally to use the characteristics of water to flow to a low place to directly put seawater in, which is incomparable to any water pump in terms of flow, but the position is high, this trick must not be used, and can only use a high-pressure water gun to spray water to try to extinguish the fire. However, because of the limited amount of water, it is not only difficult to extinguish the fire, but also because the aluminum powder can react with water at high temperature to produce hydrogen and release a large amount of heat energy, resulting in a secondary explosion after hydrogen and pulverized coal are mixed with air......
As a result, after only one shell, the Blake had to withdraw from the battle to extinguish the fire and save itself, but the two Chinese warships did not want to let it go, and soon two more 210mm blasting shells hit the Blake, making its injuries more and more serious, and if it were not for its sister ship Blenheim desperately rushing over to cover its retreat, the Blake, which had completely turned into a fireship, would definitely be sunk on the spot......
However, the Blenheim broke out of the queue because of this, and because of the change in course, the distance and the two Chinese warships quickly shortened, Yang Yonglin, who was very upset about the Blake's escape, suddenly discovered a new fighter plane, and immediately asked the radio to send an order to the Yangwei, let it attack with the Chaoyong, "Break this rafter for me first!" ”
Due to the distance and course, the Brave and Yangwei's shelling hits were significantly improved compared to the previous attack against the Blake, and the Blenheim was spared a chance to survive at all.
In less than two minutes, seven 210mm blasting shells hit the Blenheim, causing the fire on the ship to spiral out of control, the loud sound of ammunition exploding, billowing smoke from the Blenheim, and worse, even the speed of the ship began to drop rapidly.
But Yang Yonglin frowned, "It's incredible, it's all beaten like this, and it's still not sinking, it's much stronger than the original Yoshino." ”
"After all, it's a large ship with a displacement of nearly 10,000 tons, and it's not the same as a small ship like the Yoshino." , The political commissar of the Chaoyong smiled when he heard this, "But the most important thing is that this warship is for the British's own use, so there is less moisture, I think unless they can break their dome armor, even if these warships are badly injured, it will be difficult for them to sink by themselves......"
"Then change to armor-piercing bullets, I just don't know if I can penetrate (the Blenheim's dome armor) at this distance?" Yang Yonglin felt that he was not very sure, so he asked Li Yong, the "technical staff officer" on the ship, to come over, and the "technical staff officer" was a newly established position in the Chinese Navy not long ago.
Li Yonglin has always been silent, if it weren't for the strange name, Yang Yonglin would have to ignore his existence, but after calling him, as soon as this kid spoke, Yang Yonglin immediately realized his extraordinary, and he also had a deeper understanding of the brand-new position of "technical staff officer".
"The thickness of the side armor of the Blake has reached 152 mm, and there is a certain inclination, coupled with the protection of the coal seam, it looks like the defense is still good." After Li Yong praised a few words with some reservations, he immediately turned to point out its fatal weakness, "However, this warship began to be built in 1888, and the armor steel must still be a relatively old-fashioned type, and the best is just ordinary nickel steel armor, and it can never be the more advanced Harvey nickel steel case-hardened armor, so it is actually not terrible." Even farther away, our 210-mm armor-piercing shells ensure that they are pierced and successfully detonated. ”
Yang Yonglin was suddenly overjoyed, and was about to order the main gun to change the ammunition, but suddenly heard an earth-shattering loud noise, which shook the eardrums and roared, and looked up in shock, only to see that the target he racked his brains to sink had disappeared on the sea, and as the pieces of hull wreckage fell into the sea like rain, stirring up countless columns of rushing water, the last bit of evidence of the existence of the cruiser Blenheim also disappeared completely, because the explosion came too suddenly and violently, all 570 people from the captain and below were killed, and no one was spared......
After realizing that it would be difficult for the blasting shell to sink the Blenheim, Yang Yonglin had already ordered the two ships to change the target of the attack, and it stands to reason that the British officers and men on the ship could extinguish the fire more calmly. Well, even if the fire can't be extinguished, the explosion shouldn't come so quickly, right? The ammunition depot is located under the dome armor, as long as the dome armor is not broken, no matter how big the fire above is, it should not burn to the ammunition depot, at least not so quickly?
"In order to speed up the rate of artillery fire, the British Navy has come up with a number of tricks that can pose a safety hazard, such as pre-loading ammunition and the more dangerous not closing the fire door." , Technical staff officer Li used this time but once again showed his value, he was as if he had seen it with his own eyes, and easily guessed the reason for the end of the Blenheim, "If the ammunition is lifted in advance, it should be a number of smaller explosions, not directly into the sky, so I think it should be that the fire door was not closed, and the fire burned directly to the main ammunition depot ...... together."
"It makes sense not to turn off the fire door at first, but it was quickly crippled by us, why hasn't it been closed yet?" , Yang Yonglin asked subconsciously, but immediately understood, "Oh yes, after the fire broke out, it was impossible to close the door and separate the ammunition depot and turret, the only thing that could save the warship was to pour water into the ammunition depot, but unless there was an officer who could call the shots, it would definitely be too late to ...... with the intensity of the fire at that time." )
