The development of torpedoes has also gone through several aspects. From the initial black powder torpedo and picric acid torpedo, to now, the development of torpedoes has gone through many stages. The current German torpedoes threaten old battleships and ordinary cruisers at most. The threat to new battleships has extremely small capacity, and the key is the charge and speed.

A torpedo with a speed of less than 3 kilometers and a speed of about 35 knots may pose a huge threat to the main battleships of the Iron Craft era, but for warships with an average speed of 25 knots or even faster, the relative speed has been reduced to an extremely low level. With a relative speed of less than 10 knots, how much danger is there?

Relative speed is the key for ships to avoid. The relative speed of 20 knots was very difficult for ships to dodge. Now it is only 10 knots, and even if they can drive the force to the limit, it will be less than 6 knots. Such speed can be avoided with a slight change. For the main battleship in the battle, the torpedo is really just an auxiliary function.

The current torpedo is still in the era of multiple torpedoes. China introduced an electric torpedo from Germany, and it is also preparing to introduce compressed air torpedoes. However, after Yang Yuanzhao learned about the electric torpedo, he immediately discovered its advantages. Compared with ordinary torpedoes, his waterline is almost negligible, his operation is stable, and his noise is also low. As for the charge, speed and range, he has ways to improve it.

The speed of electric torpedoes comes from electric motors. Yang Yuanzhao doesn’t know much about torpedoes. Although he knows some excellent torpedoes, such as the oxygen torpedoes from Japan during World War II, the magnetic torpedoes from Germany during World War II, the sound-oriented torpedoes from Germany, etc. These torpedoes only know the names but don’t know how to make them. Yang Yuanzhao is not an expert in torpedoes. He also has no ability to make a new torpedo, which is too big.

However, it is OK to make changes to a torpedo, especially in terms of electric motors and engines. Yang Yuanzhao is very powerful. As a power expert, he has some commonalities between the motors and the engines. When Yang Yuanzhao traveled through time, he also carried some motors, plus the master of Trass, a high-power motor, but if the battery problem is not solved, then everything is a flower in the mirror and a moon in the water. The power consumption of high-power motors is greater, and the torpedoes are empty.

The battery field is the most difficult to improve. If all the motor introductions can be filled with a house, the battery introduction may be completed in a few pages. That is, after World War II, the new materials have been promoted, and the main thing restricts it is the materials. As long as the materials are studied at the top level and the materials suitable for becoming batteries are found, the performance of the batteries can be greatly improved.

Materials has never been a problem that bothers China. In terms of materials science, China is equivalent to standing on the shoulders of the 21st century. Of course, not all industries, but in some relatively high-end industries, China's strength in materials has even surpassed that of the 21st century.

Materials have some contingency in themselves. Later generations have led to major countries gaining the upper hand with strong investment and foundation. This is a business where one person wins all. The emergence of all-in-one machines has given China this opportunity. As long as it is a product that appears on the market, all-in-one machines can be obtained through analysis, mastering its material formula, and even some processing channels.

The formula of ten thousand materials every day is mostly garbage and useless materials, but there is a flash of inspiration from countless persistence, especially when materials science in the northwest has entered a certain fast lane, he can move closer to those materials regularly, so that efficiency can be achieved. However, in Yang Yuanzhao's hands, there are tens of thousands of materials suitable for batteries, most of which are by-products, but at least 20 of them are quite outstanding, and even surpass later generations in battery capabilities.

The Northwest has good battery materials, including nickel-hydrogen, lithium batteries, and even solar cells from 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, the battery performance of these things is very excellent. If these are used in electric torpedoes, electric torpedoes are terrible weapons.

Yang Yuanzhao did not intend to push the batteries to that era. Those things were almost dying. When lead-acid batteries had not developed to the extreme, they rashly entered another battery era. The foundation was not solid, just like a castle on a beach. Once waves rushed over, there would be no. What China wants is sustainable development, not a bio-raising. In other words, for computers, due to special reasons, there was no way out, and it could only be taken out first, develop software, and then make up for it in more than ten years, or even decades.

Even if it is a lead-acid battery, its efficiency can be improved after using some added materials. The torpedo used in China has basically been modified to a certain extent on the basis of Germany. To a certain extent, the battery capacity has been increased by 4 times and the motor power has been increased by 3 times. This is at least 50% when the speed is close to doubling.

The most important thing about a torpedo is its speed. It has increased from 35 knots to 65 knots, but it has only been about 30 knots. However, for warships, it is basically quite difficult, because the speed increase brings dodging advantages, and it no longer exists. What is even more terrifying is the range of 50%. This is very large for the power of torpedoes. Don’t underestimate this 50%. In raid warfare and submarine warfare, 50% range is extremely critical. Of course, fluid mechanics has been entered into the torpedo by Yang Yuanzhao, further increasing the speed of the torpedo. In fact, ships, aircraft, and even all things related to speed will be affected by fluid mechanics, especially with the increase in speed, the fluid structure will change.

For example, during World War I and World War II, ships were almost the same, but most modern ships used square tail rudders. The reason is the performance and stability of high speed. Among the torpedoes that Yang Yuanzhao knew, there would even be a blizzard similar to the cavitation effect in later generations. The thing is the same as missiles, with a speed of more than 180 knots, which is a speed of hundreds of kilometers per hour. If developed in this era, it would definitely be a killer among killers, then there would be no need for a submarine. Just destroy the ship directly, aim and go directly to fight. There would be no problem with one battleship.

The motor and battery are very good to solve. The change in charge volume when the motor and range is expanded. The reliability is relatively weak when the charge volume is too high. To a certain extent, it is unsafe. The submarine itself is strong in attack and defense. In this case, any danger is extremely harmful to the submarine. After all, the submarine is a high-risk industry. Any slight damage will cause the entire submarine to face a catastrophe. How to balance the power and safety of the torpedo is also the continuous combat capability of the submarine. Regarding the development of torpedoes, electric torpedoes are only one direction, with a relatively close range and a slow speed. In the first battle, it is barely enough. It is very unsuitable for fast battleships and battle patrols. However, after China's improvement, it increases its speed and power, and the torpedo has also become a powerful weapon.

In addition to the transformation of torpedoes, the transformation of the submarine itself is also underway. In terms of power, the combination of diesel engines and batteries allows the submarine to make breakthroughs underwater with relatively quietness. This is simply a stealth device for finding submarines without sonar and just by relying on their feelings. In this case, the safety of the submarine is extremely guaranteed.

The larger tonnage is the focus of the submarine. From 1,200 tons to 2,400 tons, it not only requires improvements in power, but also for many aspects such as firm structure and keel. The new alloy is not only strong, but also light. To a certain extent, the same volume is at least 50% lighter than other metals. The most important thing is that it has extremely strong strength. The power provided by the modified large diesel engine is at least 2 times higher than that of Germany's most advanced type, which directly shows the performance of the submarine. The water surface section, 16.5 knots underwater, 7,000 nautical miles/14 knots underwater, 165 nautical miles/16.5 knots underwater, and the safe diving depth is 220 meters. The torpedo launcher is also the first four and the second behind. It has 6 launchers, and the number of torpedoes stored has reached 64.

This is already the strength of a World War II-level submarine, with a 7,000 nautical miles range on the surface. According to 340 nautical miles a day, even if the submarine is fighting at full speed outside, it can last for 20 days. If lurking and combat missions are added, it can easily reach one and a half months. Such a submarine is truly suitable for ocean-going and long-term combat. 64 torpedoes, if 4 are issued in one battle, can support at least 16 battles and can fight almost every day.
