Zhou Yu is deeply dissatisfied with his two Saxony-class armored battleships A1 and A2!
Why? Because in Zhou Yu's opinion, the Saxony'-class armored battleship has too many flaws. The power is too small, the speed is too low, the endurance is extremely poor, and the structure of the whole ship is extremely unscientific. What is even more bizarre is:
The Saxony-class armored battleship actually has four large chimneys, so Zhou Yu prepared to forcibly modify the Saxony-class armored battleship by himself. Although he had never done it himself and the workers had no experience, he still had endless knowledge in his head.
, and Zhou Yu, who has forward-thinking vision, cannot tolerate the Saxony'-class armored battleships serving in their own naval fleet under any circumstances.
After boarding the A1 command ship, Zhou Yu only said a simple hello to Zhang Long, Ye Fu, Lu Han and others, and then plunged into the cabin. No one could be seen immediately, and he even
Even the A2 ship did not go, which made Ye Fu and others extremely depressed.
However, on the contrary to Zhou Yu's dissatisfaction, Ye Fu and others were particularly excited because their troops also had giant ships and cannons. What a state it was like! These were all real armored giants.
Ship!
When they stood on the command tower, they had tears in their eyes. With two trembling hands, they carefully and carefully caressed every inch of the armored battleship, as if they were caressing the delicate body of their newlywed wives.
I am in a pilgrimage mood, and I have a sour feeling in my heart. Our weak China also has its own armored giant ship. What the principal said before has come true.
In order to live up to the ardent expectations of the principal (the current army officers and soldiers all affectionately call Zhou Yu our principal), they practiced desperately on the way home, hoping to use their navy as soon as possible.
Develop a certain fighting capacity.
Under the almost harsh training provided by German military personnel, the officers and soldiers of the two ships were quickly able to skillfully operate the warships. This situation surprised the German technical instructors!
They all whispered in their hearts that the learning speed of the Chinese people was simply incredible and too perverted.
But this also has very serious consequences, that is, the fleet has not yet arrived in Hawaii, and the ammunition stored on the two warships has basically been consumed.
Although Zhou Yu can still afford it with his current financial strength, it would still be very distressing if Zhou Yu knew about it. It is not easy for us to make money these days! I have to cheat and deceive myself to win this family business.
Is it easy for me? Pig’s feet are not easy to make!
By the time the fleet arrived safely in Pearl Harbor in May, it was already brand new. The fleet had borrowed the German flag along the way, so the road was quite calm.
But Zhou Yu didn't even care about the people who came to greet him, with a look of anticipation on his face. Chen Fang and others were polite, briefly greeted them, and went straight into Laval's steam engine laboratory.
Gone inside.
In the laboratory, Zhou Yu discovered that Laval's triple-expansion reciprocating steam engine ran into the final problem: the condenser.
So Zhou Yu also devoted himself to research. Based on the information in his mind, Zhou Yu built a super large air-conditioning condenser. His eyes were red and his body was covered with oil. Laval was so excited that his hometown dialect jumped out:
Great, great! My dear! Ling Zhou Yu was covered in goosebumps. He thought to himself, this handsome guy doesn’t like this, so don’t think too much! If you are interested, you should go to Thailand to see it! No.
Do you know if transvestites have appeared in Thailand now?
However, in the end, Zhou Yu still faced the risk of being trapped and assigned Laval the research and development project of the steam wheel set, as well as the relevant technical data and drawings.
Now that the power of the battleship is available, the details of improving the follow-up are left to Laval. I have to work on the next project! I am busy! I don’t have time. Someone is comforting himself in his heart.
Then Zhou Yu spent a week making a simple model of the new 'Saxon' class armored battleship that he designed himself, and asked Wei Han, Chen Zhao'ao and others to follow the model and the drawings and technical information provided by him.
, carried out the main modification of the A1 and A2 ships. But he himself went to various production lines to carry out the necessary mechanical upgrades.
Wei Han and others were full of praise for Zhou Yu's timeless battleship model design method. It also provided an advantageous method for Zhou Yu Group to build battleships in the future...
At the same time, Zhou Yu also developed the rapid-fire cannons he developed, including twelve-inch (305mm) 35-caliber, 234-mm forty-caliber, forty-caliber 152-mm, single-barreled 76-mm and 37-mm calibers.
The production drawings and technical materials of the rapid-fire cannon were given to them.
When Wei Han and others saw Zhou Yu's newly designed 'Saxony' class armored battle cruiser, they were stunned and foamed at the mouth. Why? Because Zhou Yu called it the 'Saxony' class armored strategic heavy cruiser.
The data for ships rather than battleships is too exaggerated.
In that era, had anyone seen a battlecruiser with a standard displacement of 8,100 tons? In the eyes of Wei Han and others, this battlecruiser was directly a hedgehog ship, with the decks everywhere and the layout of the battlecruiser being reasonable.
Naval gun.
Next, Zhou Yu stopped the production of ordinary iron-carbon alloy steel at the Hawaii Steel Plant and switched to the production of alloy steel designed by himself that meets his own resources and technological conditions. For this reason, Zhou Yu also improved some processes.
The alloy steel information provided by Zhou Yu is: later generations of q235b grade steel, here referred to as qb alloy steel, its tensile strength and yield point are very suitable for ships compared with those in later periods of history.
At that time, when refined iron armor was still commonly used in various countries around the world, Zhou Yu's use of QB-grade alloy steel was completely abnormal.
Zhou Yu threw relevant drawings and technical information, as well as professional books containing tables of chemical elements, to Zeng Hongji, Zheng Qinglian and others, and asked them to be responsible for leading the small-scale trial production of new steel materials, requiring them to meet the above
Only with specific requirements for QB grade steel can it be produced on a large scale.
The displacement of the A1 and A2 ships designed and modified by Zhou Yu is 9,150 tons with full load.
Its length, width and draft are slightly higher than that of the Saxony-class armored ship.
The speed is twenty knots under normal power pressure.
In order to consider speed, Zhou Yu greatly reduced the armor, adopted a key protection layout, and the hull adopted an external floating structure.
The external floating type not only makes the hull lines smooth and flexible, but also makes the side defense of the battleship absolutely powerful.
The main gun is a self-developed twelve-inch (305 mm) three-gun 35-gun caliber. It adopts the layout of two in front and one in rear, and the rotating main turret is fully hidden.
The secondary battery consists of four 204mm forty times caliber breech-mounted rifled guns, one in the front and one in the rear, one on each side, with a semi-hidden rotating turret.
The profile guns are six single-barreled 152mm profile guns with a caliber of 40 times.
Eight single-barreled 76mm rapid-fire guns mounted on the deck and sides.
Four twin 37mm anti-torpedo rapid-fire guns.
Three 350mm torpedo tubes.
The main engine is an eight-seat triple-expansion reciprocating steam engine with three shafts for propulsion, and the main boiler is an eight-seat Miyahara coal-water tube boiler. There is reserved space for the installation of a high-power diesel engine.
The estimated crew is 580 people.
Zhou Yu stopped and thought about it, and found that the battleship's communication system was still very primitive. When the two armies were fighting, it was not possible for all elements to fire volleys simultaneously, so he designed an internal telephone communication system for the battleship.
There is also distance measurement. Under the current conditions, radar and laser have not been developed, so Zhou Yu has to make do with the most primitive primary optical distance measurement method that uses the principle of trigonometric functions.
The optical system is divided into two objective lenses (right and left) (that is, the windows extending out on both sides of the turret), and the left and right optical paths are imaged on the upper and lower sides of the eyepiece respectively.
That is to say, when viewed from the eyepiece, the upper half is the image of the right objective lens, and the lower half is the image of the left objective lens.
When observing a target through a rangefinder, the left and right lines of sight will form an included angle. At different distances, the included angle will be different.
As long as you know the size of the included angle, you can find the target distance through trigonometric functions.
At a distance of 20,000 meters, as long as the observer is not careful at the sight angle 1', the sight angle deviation is as small as ±1', which is a huge difference.
If the included angle is 1′ smaller, then the measured distance is 47821 meters; if the included angle is 1′ larger, then the measured distance is 12644 meters.
It can be seen how big the error is in this principle, but before the emergence of thermal optical rangefinders and radars, there was no better alternative.
Then Zhou Yu listed the trigonometric function formulas, handed them over to Ye Fu and other naval commanders, and taught them how to use the trigonometric function optical system to measure distance. They were asked to practice a lot. Only when they are familiar with it can they
It can reduce calculation errors.
Zhou Yu also thought about explosives, artillery shells, and battleship generators, which also need to be updated in design...
Explosives Zhou Yu was going to use dynamite. Explosives in later generations have been proved to be unparalleled in their power.
The **(**) invented by Zhou Yu is white and amaranth-colored light yellow needle-shaped crystals, odorless and hygroscopic. It is a relatively safe explosive that can withstand impact and friction, but can be destroyed by any amount of sudden heat.
Cause an explosion.
It is different from a gun in that it is not sensitive to friction, vibration, and is not prone to explosion even if it is shot. Therefore, a gun is required to start it.
It does not react chemically with metals or absorb moisture. Therefore, it can be stored for many years. However, it reacts strongly with bases to form unstable compounds.
Each kilogram of explosives can produce 4.2 million joules of energy. It is worth noting that ** releases less energy than fat and sugar, but it releases energy very quickly because it contains oxygen.
It can be used as a combustion accelerant and does not require oxygen in the atmosphere.
Zhou Yu's medicine is different from the medicine invented by TJ Wilberland in a failed experiment in 1863. Some other ingredients were added to Zhou Yu's medicine, such as an appropriate amount of aluminum powder. , phosphorus powder, etc.
Putting an appropriate amount of crushed aluminum powder into the explosive will cause the explosive's fragmentation speed, air explosion, detonation velocity, violent heat and explosion power range to have a more significant and straight-line change, and its power can be said to be huge. .
Phosphorus powder is the legendary eternal fire - will-o'-the-wisp. It burns whatever it touches and cannot be extinguished by water. It is the only weapon in explosives and incendiary bombs.
Sometimes Zhou Yu would joke around and wonder if he had put aphrodisiac ingredients in the bomb so that the enemies he faced would be busy digging holes and not have the energy to shoot!
Since Zhou Yu's current warships are still small, the caliber of the artillery is also small, and the shooting distance is also very short, so Zhou Yu imitated the square-butt extended-range bomb of later generations. This technology is still very simple, as long as some are made behind the bomb. Technical processing is ok, and no advanced technology is required.
In addition, Zhou Yu also developed the APC capped armor-piercing projectile. The APC capped armor-piercing projectile is equipped with a seven-inch warhead with a more streamlined shape. The warhead uses a manganese steel technology impact cap, which greatly increases the long-range penetration of the armor-piercing projectile.
Achieving a truly thin skin with large fillings, a 250 kilogram armor-piercing projectile within three thousand meters can instantly penetrate a 16-inch ordinary carbon steel horizontal deck.
For the battleship marine generator, Zhou Yu plans to use a 500-horsepower marine generator. This can only be used after it is jointly developed with Tesla.
After Zhou Yu arrived at Tesla's laboratory, he discovered that Tesla not only invented the AC motor model based on the materials and drawings provided by Zhou Yu, but also successfully created a rotating magnetic field through alternating current. This was how AC motors were later developed. The basis for large-scale application.
He also developed a three-phase asynchronous motor and a bladeless fluid turbine generator. Therefore, Zhou Yu also had a marine generator, so he didn't need to worry about it.
This generator is simple, compact, and extremely efficient. It is an "invincible" device. It far exceeded Zhou Yu's initial expectations. Only now did Zhou Yudao know what a professional inventor is, a quick shooter in scientific creation.
