Open an aircraft carrier to fight against Japan

After solving the problem of the power and accuracy of the artillery, Lin Yuan is only faced with the problem of speed. No matter how fast the speed of the warship is, it is impossible to be faster than the plane, so Lin Yuan is not worried about them after mastering the advanced technology. , What threat can it pose to the Beijing ship.

This time, Lin Yuan did not arrange any display, but called foreign experts together for a symposium. Lin Yuan first asked, "How can we make warships run faster?"

An Englishman said: "I think the existing propulsion technology has reached its limit, and there is not much room for improvement. For example, the boiler part, the latest water-tube boiler, the steam pressure has reached 50 MPa; we all know, No matter how optimized the shape of the water pipe is, the flue gas generated by combustion cannot transfer heat to the liquid in the water pipe [-]%. If the flue gas is discharged directly from the chimney to the atmosphere, the heat will be wasted in vain, so we Various heat exchange measures have been designed.”

"For example, when burning coal, it is necessary to ventilate the furnace, otherwise there will not be enough oxygen during combustion. If the temperature of the air passing in is higher, it will be very helpful to improve the combustion efficiency, so we designed the heat exchange pipe , allowing the flue gas to heat the air."

"There is also the piston part. Due to the increase of the steam pressure, the steam still has a lot of residual energy after the work is done once. For this reason, we have designed multiple work cylinders to extract all the energy of the steam as much as possible. After these designs, there are not many technologies that can be improved. If there is no major breakthrough in principle, I am afraid that the speed of large warships will be limited to about [-] knots."

A German said: "If we can further reduce the resistance of the ship, then our speed can be faster, but we cannot accurately solve the hydrodynamic equations, and naturally we cannot accurately design the streamline shape of the ship..."

Everyone was chattering and talking, but the translators were embarrassed. They didn't understand those terms very well, so it was very difficult to translate, so that even though they discussed all morning, they didn't discuss many opinions.

Although Lin Yuan raised a question, he didn't express any opinion. He didn't come to the British man's room quietly until the noon break.

Lin Yuan found the Englishman who spoke first in the morning, and said with a smile: "I don't know if you have ever thought about it, but the existing steam engines work intermittently, and the steam must condense after doing work once, and wait for the piston to return to its original position. After the next batch of high-pressure steam enters the cylinder, the next work can be performed, so the speed of the ship will definitely not be increased. If we can find a way to make the steam work continuously, even a large warship can reach a very high speed.”

The British asked: "Let the steam do work continuously? What should I do?"

Lin Yuan picked up a piece of paper, drew a few strokes on it, held it in front of the British, and said, "Look at this, isn't it possible to work continuously?"

The British took the piece of paper, looked at the picture on it, widened his eyes in surprise, and said, "How did you come up with this structure? It's so ingenious."

It turned out that in Lin Yuan’s picture, a long axis was drawn, and a circle was placed on the axis, and the blades protruded from the circle. Lin Yuan said: "The high-pressure steam no longer pushes the piston to move in a straight line, but to push the blades to rotate. , the rotation of the blades also drives the rotation of the shaft, and the back of the shaft can be directly connected to the propeller as a power propulsion system."

The British said: "This can indeed increase the speed of the ship, but I don't know what shape the blade should be processed into?"

Lin Yuan smiled and said, "You know the propellers of warships, right? Water vapor and water are both fluids, and they have similar mechanical properties. You can process this blade by referring to the blade shape of the propeller."

The British folded the paper and said in a low voice, "I hope you will not tell others about this matter."

Lin Yuan pretended to be embarrassed, and said, "This is not good."

The Englishman took out his checkbook and said, "I'll give you one hundred thousand pounds, and I hope you don't tell anyone about it."

Lin Yuan pretended to be elated, and said with a smile, "Well, I just don't tell others."

Of course, Lin Yuan would not keep his promise to them. As soon as he went out, he told the experts from the other three countries about the matter. The experts from the other three countries also had the same idea as the British. When they saw Lin Yuan After extorting money many times, he thought Lin Yuan was a money-seeker, and offered a lot of money in bribes one after another. Naturally, Lin Yuan of these foreign devils would never refuse money.

What Lin Yuan said was steam turbine technology, which was widely used on warships in the early 17000th century and quickly replaced the original piston steam engine technology. As high as 21 tons, the speed has reached an astonishing [-] knots, making all kinds of battleships under research in various countries directly obsolete, and the era of dreadnoughts has since opened.

So far, Lin Yuan has disclosed the three key technologies, armor-piercing projectiles, gyroscope stabilization, and steam turbines, to experts from four countries in various forms. Only dispensable things are left for the demonstration. Today, it completely turned into a brainwashing time for foreign experts. Under Lin Yuan's arrangement, the crimes committed by the Japanese in Ryukyu were counted one by one, and all of them were shown to foreign experts.

The foreign experts also felt that they had gained a lot, and when they returned home satisfied, Shen Wanqing asked: "Aren't you trying to lure them into the path of big ships and cannons? But I see that the technology you revealed to them, It seems more appropriate to say 'quick ship quasi-cannon'."

Lin Yuan said: "In fact, there are similarities in the core between the 'fast ship quasi-cannon' and the 'big ship cannon'. If a warship wants to increase its speed, it must install a powerful engine. Such an engine has a large volume and mass. Not small, so fast ships often represent large ships; if the shells want to hit accurately, the initial velocity must be high, so that the impact of the direction-finding wind will be small. To increase the initial velocity, the most direct way is to increase the initial velocity. The amount of propellant, so it's a giant cannon."

Shen Wanqing seemed to understand, and asked, "Then what shall we do next?"

Lin Yuan replied: "Now that the governor of the Northeast has also been obtained, we can develop on a large scale in the Northeast."

Lin Yuan delineated the iron and steel industrial zone in Benxi and Fushun in Fengtian. The reason why he chose Benxi and Fushun was because of the iron and coal mines in these two places. Today's Ryukyu lacks various ores and wants to To improve the quality of steel, a certain amount of alloying elements must be added to the steel, so it is necessary to leave Ryukyu and find a resource-rich place for development.

In the production process of Ryukyu in the previous stage, it was mainly producing industrial equipment, including blast furnaces with larger output, chemical reaction vessels, etc. After the foreign experts left, these equipments were immediately loaded on ships and transported to Yingkou Port, where, Lin Yuan ordered the construction of roads and railways so that the equipment could be transported to the steel industry area.

Since there is no own shipyard, the ship used to transport equipment is still a merchant ship of Taiwanese merchants. The merchant ship broke through the wind and waves and docked at Yingkou Port. Near the port, several steam cars are waiting. These people who use steam engines as power Guy, although it is very heavy, it has a huge load capacity, which is just right for transporting items of huge mass.

A new era is about to begin.
