Chapter 153: The Impact of the Trio (Part II)
However, this is not all bad, as it makes a lot of sense to increase the firing angle to increase the range without enlarging in too much, and even slightly increase the number of ******.
After the main gun increases the caliber and muzzle velocity, the penetration depth of the armor-piercing projectile will inevitably increase, but is this enough? You must know that Li Hui's imaginary enemy in designing this new warship is a majestic battleship, and the latter's waterline armor is 9 inches (229mm) thick Harvey nickel steel armor, and according to the actual combat performance in the Russo-Japanese War, the 180mm Harvey nickel steel armor can completely resist the attack of 40 times the diameter of the 305mm cannon!
But the conclusion is sufficient, Li Hui dares to boast of such a Haikou, naturally because of the evaluation data given by the system. After being verified by countless facts, Li Hui now has full trust in him.
More importantly, the 210mm main gun in the Yangtze River Estuary can penetrate the 102mm thick Harvey nickel steel armor, which has greatly surpassed the armor-piercing shells in the Russo-Japanese War in history.
As for the principle, Li Hui has basically figured it out after carefully comparing the differences between the Japanese-Russian armor-piercing bullets and the armor-piercing bullets he designed.
Due to the limited research progress of system science and technology, in terms of structure, there is no fundamental difference between the armor-piercing bullet designed by Li Hui and the two sides in the Russo-Japanese War, and the better material of the projectile body is somewhat helpful to the armor-piercing ability, but the degree is very limited, the real difference should be the difference in the charge of the shell.
"That's the problem." After Li Hui found this, he immediately remembered the British Royal Navy's 1915 artillery manual that he had read before the crossing, which mentioned that the actual penetration depth of the armor-piercing bullet using picric acid charge was only less than three-quarters of the armor-piercing bullet of the same type using black powder.
Compared with the penetration data obtained from the pre-war test, the armor-piercing bullet in the Russo-Japanese naval war was able to hit five or six percent of the penetration depth, which was too big for the technical personnel of the navies of various countries at that time to be puzzled, and it was not until much later that they figured it out.
In fact, this is because in order to better observe during the test, the explosives in the armor-piercing shells are replaced with sand or salt blocks, while in actual combat, the armor-piercing shells have explosives in them, and after being squeezed and rubbed in the process of penetrating the armor of the enemy ship, the explosives will be detonated in advance without waiting for the fuse to be activated, so that the armor-piercing shells cannot hit the theoretical penetration depth at all. The less explosives and the more blunt the type of explosives is contained in the armor-piercing projectile, the later the early explosion will appear, and the deeper the penetration in actual combat will be closer to the theoretical value.
Silver explosives are infused with a large amount of aluminum powder, so they are extremely blunt, far from picric acid and black powder can be compared, and the armor-piercing projectile with it as a charge can even hit a penetration depth equivalent to seven or eight percent of the theoretical value in actual combat, which can ensure the penetration of the main armor belt of the 9-inch waterline of the majestic class at a distance of 4,000 meters (the effect of the angle of incidence has been calculated).
Considering that the armor of the Majesty-class battleships in the simulation is calculated according to the system product, it is generally slightly worse than this in actual combat, and it is naturally easier to penetrate, so even at a distance of 5000 meters, there should be no problem in general.
Besides, even if you are too unlucky to break through directly, if you are only a little close, you will at least be able to blow it up, and a big hole in the waterline armor that cannot be blocked will also pose a great threat to the warship.
Since there is no longer a need to cooperate with the old ships of the Beiyang Naval Division, there is no need for the new ships to take into account the two formation methods, so Li Hui decisively gave up the congenitally deficient diamond-shaped layout, and adopted a full-center axis main gun layout similar to that of most dreadnoughts, which can fire a salvo of 8 275mm main guns when facing the enemy sideways, if you take into account the overwhelming advantage of this classic naval gun named by Li Hui as "Yiwei 40 times diameter 275mm rapid-fire gun", this is almost equivalent to more than a dozen (armor-piercing shells)/ The firepower of five or six (blasting) Majesty-class battleships
Compared with the greatly strengthened firepower, because the protection of the Haitian-class patrol is currently sufficient, Li Hui has not further strengthened it, and the maximum thickness is only 155mm Krupp armor. Anyway, the new ship will not be built immediately, and even if the Western powers can come up with more blunt high explosives and armor-piercing shells in advance, he can change the design plan temporarily
The Royal Navy was the envy of the Royal Navy for its speed, but Li Hui knew that its potential was far from being realized, with the stubby shape of the diamond-shaped main gun layout increasing the resistance to navigation and the limited tonnage size making it impossible to install the most powerful power system available, but now neither was a problem.
In the end, the new ship adopts a three-axis drive, and its conventional output power reaches 24,000 horsepower, which is equivalent to the state of Haitian class with strong pressure ventilation, and if she also turns on strong pressure ventilation, its ultimate output power can exceed 35,000 horsepower, so that the new ship can run at a terrifying speed of 24 knots with a standard displacement of close to 14,000 tons and a huge hull with a normal displacement of 16,600 tons
The new ship was modeled after the armored cruiser, but the firepower and tonnage of the battleship, and the astonishing speed that could almost be compared to that of the light cruiser, marked the emergence of a completely new ship type.
In fact, if you only compare the technical parameters, this warship that is still on the drawing board is a shrunken version of the first battle cruiser in history, "Invincible", and her appearance will definitely shock the whole world, and the technological revolution and arms race caused by the "dreadnought" in history will also start in advance.
However, strictly speaking, most of the components Li Hui chose were actually products launched in 1898, which is only three years later than now, but it is really amazing that these not particularly advanced technologies can be integrated to create such a powerful weapon. Perhaps this is the most attractive and unique charm of the military industry, right?
In fact, Li Hui is now so fascinated by it that he can't even tell whether he is in such a hurry to design a more powerful new ship when the Haitian-class is fully equipped with patrols, whether it is to take precautions or to take advantage of the opportunity to enjoy it (to be continued). )
