The development of torpedoes has also gone through several aspects, from the very beginning of the black powder torpedo, picric torpedo, to the present, the development of torpedoes has gone through many stages, the current German torpedo, at most, threatens the old battleships and ordinary cruisers, the threat ability of the new warship is very small, the key is the charge and speed.

A torpedo with a speed of less than 3 kilometers and a speed of only about 35 knots may be a huge threat to the capital ships of the ironclad era at about 15 knots, but for warships with an average speed of 25 knots or even faster, the relative speed is reduced to an extremely low level, and with a relative speed of less than 10 knots, how much danger is there?

Relative speed is the key to the ship can dodge, the previous relative speed of 20 knots, even if the ship wants to dodge, it is very difficult, now it is only 10 knots, and even the limit of the afterburner, less than 6 knots of speed, such a speed, a slight change, you can dodge, for the capital ship in the battle, the torpedo is really just an auxiliary role.

The current torpedo is still in the era of a variety of torpedoes, what China introduced from Germany is an electric torpedo, and it is also preparing to introduce compressed air torpedoes, but after Yang Yuanzhao knew about the electric torpedo, he immediately discovered its advantages, compared with ordinary torpedoes, his waterline is almost negligible, the operation is stable, and the noise is small, as for the charge, speed and range, he has a way to improve.

The speed of electric torpedoes comes from electric motors, Yang Yuanzhao does not know much about torpedoes, although he knows some excellent torpedoes, such as Japanese oxygen torpedoes during World War II, German torpedoes during World War II, magnetic torpedoes, sound-guided torpedoes, and so on. These torpedoes only know the name, but they don't know how to make them, Yang Yuanzhao is not an expert in torpedoes, and he does not have the ability to make a new torpedo, which is too big a leap.

But for a torpedo, changes were made. But it can, especially in terms of electric motors, motors and engines, Yang Yuanzhao's strength is very strong, he is a power expert himself, and the motor and the engine have some commonalities. The high-power electric mechanism was made, but if the problem of the battery is not solved, then everything is a flower in the mirror, the moon in the water, the power consumption of the high-power motor is greater, and the lifting of the torpedo is empty.

The battery field is the most difficult to get promoted, if all electric motors are introduced. The ability to fill a house, the introduction of batteries. Maybe a few pages can be written, that is, since World War II, the new materials have been popularized, and there has been a further improvement, and the main thing that restricts him is the materials, as long as the material research is up to a higher level. Find a suitable material to be used as a battery, then the performance of the battery can be greatly improved.

Materials have never been a problem that plagues China, there is an all-in-one machine, and in materials science, China is equivalent to standing on the shoulders of the 21st century. Of course, not all industries, in some of the more sophisticated industries, China's strength in materials even exceeds that of the 21st century.

Materials, itself with a certain accident, later generations are the major powers with a strong investment and foundation, occupy the upper hand, this is a one-man all-win industry, the emergence of the all-in-one machine, so that China has this opportunity, as long as it is a product on the market, the all-in-one machine can be analyzed, master its material formula, and even some processing channels can be obtained.

The formula of 10,000 kinds of materials every day, most of them are garbage, useless materials, but countless insistences in the flash of inspiration, especially the northwest materials science into a certain fast lane under the premise that he can regularly move closer to those materials, so that the efficiency is there, but in Yang Yuanzhao's hands, there are as many as 10,000 materials suitable for batteries, most of which are by-products, but at least 20 of them are quite outstanding, in terms of battery capacity, even more than later generations.

The Northwest has good battery materials, nickel-metal hydride, lithium batteries, and even solar cells in later generations, these are among the electronic products he carries, and there are some new products, through the analysis function of the all-in-one machine, it is easy to get the battery performance of these things is quite excellent, if these are used in the electric torpedo, the electric torpedo is a terrible weapon.

Yang Yuanzhao also did not plan to push the battery to that era, those things, almost out of generation, when the lead-acid battery did not develop to the extreme, rashly entered another battery era, the foundation is not solid, just like the castle on the beach, once there are waves rushing over, there will be none, China wants sustainable development, not the rise of life, that is, the computer, due to special reasons, there is no way, can only be taken out first, develop software, and then use it for more than ten years, Or even decades to make up for it.

Even if it is a lead-acid battery, after using some additional materials, it can improve its efficiency, the torpedo currently used in China, basically on the basis of Germany, the motor and battery have been modified to a certain extent, to a certain extent, so that the capacity of the battery has increased by 4 times, the power of the motor has increased by 3 times, which is close to doubling the speed, the range, at least 50%.

The most critical thing about torpedoes is speed, which has increased from 35 knots to 65 knots, only about 30 knots, but for battleships, it is basically quite difficult, because the increase in speed brings dodge advantages, and once again it does not exist, and what is even more terrifying is the 50% range, which is very big for the power of torpedoes, don't underestimate this 50%, in raid warfare and submarine warfare, 50% of the range, extremely critical, of course, fluid mechanics, or Yang Yuanzhao into the torpedo, The speed of the torpedo is further increased, in fact, ships, airplanes, and even everything related to speed will be affected by hydrodynamics, especially with the increase of speed, the fluid structure will also change.

For example, during World War I and World War II, ships were almost the same, but on modern ships, most of them used square tail rudders, the reason is the performance and stability at high speed, as far as Yang Yuanzhao knows, there will even be a similar cavitation effect of the blizzard in later generations, that thing is the same as missiles, the speed is more than 180 knots, that is a speed of hundreds of kilometers per hour, if it is developed in this era, it is definitely a killing weapon among killing weapons, then there is no need for submarines, direct destroyers, Aim and go straight to fight, and it's no problem to take a battleship at a time.

The motor and battery are a good solution, in the case of the motor and the expansion of the range, the change of the charge will become a problem, the charge is more, the reliability, it is relatively weak, to a certain extent, it is not safe, the submarine itself is strong and weak, in this case, any one, the danger is very harmful to the submarine. After all, the submarine is a high-risk industry, any little damage, will make the entire submarine face the catastrophe, how to balance the power and safety of the torpedo, but also the submarine's continuous combat capability. Regarding the development of torpedoes, electric torpedoes are only one direction, the range is relatively short, the speed is relatively slow, in World War I, it is just barely enough, against fast battleships and battle cruisers, it is very inapplicable, but after increasing China's improvement, increasing speed and power, torpedoes have become a powerful weapon.

The new generation of attack submarines, in addition to the transformation of torpedoes, the transformation of the submarine itself is also underway, in terms of power, has always been the strongest in the northwest, the combination of diesel engine and battery, so that the submarine can be relatively quiet underwater, can be relatively quiet to break through, which is not sonar, just by feeling to find the submarine, it is simply a stealth device, in this case, for the safety of the submarine, there is a very high guarantee.

Larger tonnage, this is the focus of the submarine, from 1200 tons, to 2400 tons, not only need to improve the power, but also need for the stiff structure, keel and many other aspects, the new alloy, not only strong, but also light, to a certain extent, the same volume, than other metals, at least 50% lighter, the most important thing is that his strength is extremely large, after the transformation of the large diesel engine, the power provided, than the most advanced type in Germany, at least 2 times higher, directly shown to the performance of the submarine, 23 knots on the surface, 16.5 knots underwater, 7000 nautical miles / 14 knots on the surface of the water, 165 nautical miles / 16.5 knots underwater, safe diving depth of 220 meters, torpedo tubes are also four in the front and two in the back, with 6 533MM launch tubes, and the number of torpedoes in storage has reached 64,

This is already the strength of World War II submarines, 7000 nautical miles on the surface, according to 340 nautical miles a day, even if the submarine is fighting outside at full speed, it can last for 20 days, if you add latent and combat missions, it can easily reach a month and a half time, such a submarine is really suitable for ocean-going operations and long-term operations, 64 torpedoes, according to a battle issued 4, can support at least 16 battles, almost every day.

Such a submarine can definitely be called worth looking forward to, because the project of change is huge, even the hull needs to be redesigned, the underwater submarine design is much more difficult than the surface ship, China has computer-aided design, and the final formation also needs continuous sea trials, that is, in the autumn of 1915, most of the sea trials were completed, and the final type was finalized, and the number of new attack submarines owned by the whole China has reached 41, except for 10 remaining in China, the rest, will be sent to the North Atlantic in this operation against the Entente.
