Ito first said: "Today's meeting is attended by experts in the navy of the Great Japanese Empire, and we have only one topic on the topic of today's meeting, that is, what kind of fleet we want to build to defend the dignity of our Great Japanese Empire!" ”

A voice first said: "If we want to build a navy, we must first determine our opponent, and our main opponent is that mysterious ship!" ”

Another voice chimed in: "Yes, I agree with this opinion, as we all know, the most powerful navy in the world is the Royal Navy of the British Empire!" But judging by the strength displayed by this mysterious ship, the fleet of the British Empire is a child's toy compared to it. ”

Ito said: "First of all, the speed of our fleet's warships is too slow, and at the beginning of the battle, our fleet has approached the mysterious ship, and it seems to have suddenly appeared in front of us, and our naval guns have been able to attack it, but let it escape. ”

Everyone was silent, and everyone knew that the fastest speed of the warship at that time was only twenty knots, and it was a fool's dream to reach the speed of the mysterious ship at thirty knots.

Ito Yuhiro also said: "The main guns of our warship are obviously insufficient, and our Fuso ship has already hit it by firing, but unfortunately it has not caused much damage to it. ”

A voice said, "Regarding the power of the artillery, we should increase the range of the artillery, so that we can have an advantage in the confrontation with the mysterious ship." The only way is to increase the caliber of the artillery, the larger the caliber of the artillery, we can add more propellants, and the warhead can be made larger, so that the power of the artillery will naturally go up. ”

Ito said: "This is not easy to say, our current displacement of the largest Sanjing ship is not more than 5,000 tons, this tonnage of ships, equipped with 320mm caliber guns, the muzzle will have an impact on the stability of the ship when rotating, so if you want to increase the caliber of artillery, you must increase the displacement of the ship, can we build a warship with a displacement of 10,000 tons?" ”

A voice said: "The solution to this problem is the same as the speed, we want to build faster warships and warships with larger displacement, the fundamental way is the same, improve the power system." ”

Ito said, "How do you think we should improve the powertrain? ”

The voice said: "There are two ways to improve the power system, the easier is to improve the design of the ship, that is, to optimize the facilities on the ship, and remove some unnecessary equipment." For example, proponents of ramming tactics have been obsessed with the Battle of Lissa in 1866, in which the Austrian flagship used ramming to successfully sink an Italian warship, but in the face of the mysterious ship, we found that it was impossible to get close enough to ram, so we simply removed the ramming. ”

Ito said, "Your opinion is good, who else has any opinion?" ”

Another voice said: "Our Sanjing ship is still using fire-tube boilers, I think we should be fully replaced with water-tube boilers, water-tube boiler tubes are water inside, through the external high temperature to make water change into steam, and fire-tube boiler tubes are high-temperature gas, the periphery is water, turn the peripheral water into steam and then do work, limited by the material, the steam supply pressure of the fire-tube boiler is difficult to exceed 2 megapascals, and the gas supply pressure is high, the speed of the ship increases, so we should improve the fire-tube boiler into a water-tube boiler." ”

A voice said, "But there is a lot of salt in the sea, and these salts form salt scale, which accumulate in the pipes, and it is not easy to clean them up." ”

The voice said: "I have considered this, we can add a seawater filtration device to the outside of the boiler, and use chemical means to remove the inorganic salt ions in it to achieve the purpose of seawater desalination to reduce the accumulation of salt scale. ”

Another voice said: "In addition, we can also modify the steam engine part, as we all know, if you want to increase the efficiency of the steam engine, you have to find a way to increase the initial temperature of the steam, I think we should improve the pressure air supply device, in our current warship, there is indeed a way to use pressure air supply to improve the combustion efficiency, but this device is still relatively simple, we should redesign this device." ”

A voice said: "The steam engine we use on our ships now is to let high-pressure steam push the piston, and the piston converts the linear motion into rotary motion through the crank connecting rod mechanism, in this process, the loss of mechanical energy is relatively large, if we can let the steam directly push the shaft of the propeller, then the efficiency will be greatly improved." ”

Ito said, "I think this is a good idea, but is it difficult to implement? ”

The voice said: "Now it seems that it is still relatively difficult to realize, there is no problem in the basic theory, the problem lies in the engineering implementation, for example, if you want to let these steam directly push the shaft of the propeller, the shaft must have blades, such a large size of the blade, the rotation speed is very large, and the centrifugal force it is subjected to will also be very large, so it will inevitably bring strength problems; There is also the problem of vibration, at present, we do not have a deep understanding of the vibration dynamics of the rotor, and there will be a lot of very detailed problems in the field of engineering, to give a very simple example, there can not be only one shaft in this system, because the whole system is very large, so how to connect the two shafts, how to select the connection stiffness, these are the things that need our further study. ”

Another voice said, "Your Excellency, in fact, these problems boil down to one question, and that is the question of whether we have money or not. These studies are supported by large sums of money, and we are not sure if the government can give us enough funding. ”

Ito Yohei smiled: "This question, the professors here don't have to worry, even if we don't have money to eat, we have the money to build a navy!" ”

Only Ito Yuheng laughed a few times, and everyone knew that in order to strengthen armaments, the Japanese government invested half of its annual fiscal revenue in army building, and no one dared to question the significance of doing so.

Ito said: "Now let's discuss the issue of weapons and equipment, I think that kind of flying machine will definitely become something that dominates the battlefield in the future!" Ladies and gentlemen, can we make something like that? ”

Lin Yuan heard a voice at this time, which was the one who spoke in the last meeting, he said: "We went back and analyzed the idea of building an airplane, and found that there was a problem with our original idea, we wanted to use the backward injection of air to do work, which was too difficult, so we also chose to use propellers for propulsion." ”

"If an airplane wants to overcome gravity and fly into the sky, it must be subjected to the vertical lift, which we found when we followed the aerodynamic development of Western countries, the Russians such as Kovsky deduced the formula of lift around the cylinder, according to this formula, we can design the shape of the wing, although the calculation of this design is very rough, but we can verify the shape of the wing through subsequent experiments."

"Then we have to face the problem of the rotation of the power plant, first of all, the most mature is the steam engine, after our preliminary research found that this kind of machinery is not suitable as the power of the aircraft, it is too bulky, and it also needs to bring its own water and coal, so we want to choose the internal combustion engine as the power of the aircraft, the internal combustion engine is small, with gasoline as fuel, we decided to study and decide, the use of the internal combustion engine, so that the day when our great Japanese empire has a flying aircraft is just around the corner."

Ito said: "In this way, we also have flying planes, and it is not far from our great Japanese empire to dominate the world!" Professors, sort out your plan, estimate how much money it will cost, and in a few days I will go to the government to ask for money. With that, the meeting broke up.

Lin Yuan put down the headphones, and saw Shen Wanqing holding a mask, standing in front of him with a smile, she showed off: "Look, my mask is ready." ”

Lin Yuan asked, "When do you plan to send Shangtai away?" ”

Shen Wanqing smiled: "It's tomorrow." ”

Lin Yuan smiled and thought to himself: "This time, there is a way to kill that old guy Ito Hirobumi!" ”
