Since receiving the 13.5-inch ship ** paper, the Ministry of Foreign Affairs did not dare to have the slightest carelessness about the things sent by Yang Yuanzhao, God knows what it is, if it is a 14-inch or even a 15-inch naval gun, they may believe it, because the current British has installed a 14-inch gun, and the 15-inch is being studied.

However, the Ministry of Foreign Affairs brought in professionals to see that it was nothing more than a 640-horsepower engine drawing, and it was only a technical point written. Seeing the propulsion of thousands or even tens of thousands of horsepower of battleships, what is this counting, could it be that this Mr. Yang of the Far East, who is poor in donkey skills, thinks that this thing can impress Germany.

Just when the diplomats were ready to return this thing to the northwest, they found that a power expert was holding that drawing, excited and his eyes were shining, high-horsepower marine diesel engines have always been one of the focuses of German research, in this era, the cracking of oil is nothing more than gasoline, kerosene and diesel, gasoline because of the strong explosion, not easy to control and volatile, not very suitable for the use of ships, and diesel is not volatile, and contains greater energy, once fully combusted, can provide strong thrust, Although unprocessed heavy oil is better in terms of economy and energy, diesel is also a good direction, especially for specific areas.

The engineer who came happened to be in power, and focused on diesel research, his attention directly attracted the attention of the upper echelons, especially after learning about Yang Yuanzhao's whereabouts, knowing that he had gone to the submarine base a few days ago, accompanied by Prince William, and after that, he took out such an engine, and the result goes without saying that the diesel engine is one of the engines for the future development of the submarine.

The submarine is not a major item of the Navy, and even in the opinion of Wilhelm II, it is not too important, but this thing was sent to the Admiralty, so that they can study it as appropriate, and they can use it, and then ask about the intention of cooperation, and the Admiralty because of the instructions of His Majesty the Emperor, especially after several submarine designers heard about the power of this engine, they came to it one after another, and finally it was Tirpitz of Jingdong, after he synthesized expert opinions, he found that if this engine was feasible, It is likely that the surface speed of the submarine will exceed 18 knots, and in tonnage, it can also be more than double the existing tonnage.

The submarine is a new type of ship that Tirpitz attaches more importance to, and even in his opinion, it may be a key to breaking the contrast and duel between the capital ships for decades, but unfortunately due to financial and other reasons, the research of submarines has been relatively slow, and the key point is the engine and battery.

These two, one determines the surface speed, the other determines the underwater speed, especially the former, but also determines the tonnage of the entire submarine, there is no certain speed, the submarine does not matter, the submarine is not a cargo ship, the space is limited, the sealed space, for the members, there is a huge test, there is not enough speed, crossing the range, a few months, or even half a year to stay on it, it will make people crazy, everyone knows this. From gasoline and kerosene at the beginning, to the current research on diesel, Tirpitz heard that there has been a certain breakthrough in the Ship Research Institute, but now the Northwest has come up with a better one in front of him, which makes it difficult to choose.

For a whole day, engineers and designers have studied this engine, from the number jù, structure, size, although there is no core number jù, these marks are enough for them to evaluate the performance of this engine, and even the designer simply based on this engine, increase the cabin structure and the number of batteries, made an estimate, the speed on the water can be increased by 2 knots, the underwater is basically unchanged, and the loading capacity can be increased by 60 tons.

60 tons, when he heard the news, Tirpitz's eyes suddenly lit up, and even repeatedly asked the designer if he had miscalculated, taking 6 tons as 60 tons, 60 tons is nothing for a battleship, not to mention a battleship, there is not much difference between a cruiser with 60 tons more and 60 tons less, and even a destroyer of more than 1000 tons does not have much effect, it is just a little more coal.

However, for submarines, this difference is very big, he single-handedly promoted the establishment of submarine forces, and there is a great deal of research on submarines, among submarines, not to mention 30 tons, 60 tons, one ton, hundreds of kilograms are important, sometimes for the weight of a few kilograms, and even compress the cabins of the members, so as to save to the extreme. What is 60 tons equivalent to, take 450 mm, 120 kg charge torpedo as an example, the total weight is about 400 kg, 60 tons is equal to 150 torpedoes, of course, on the submarine, it is impossible to equip so many torpedoes, too many are not only dangerous, but also completely useless, if you do not load torpedoes, put these saved tonnage in other aspects, it is obvious that the comfort of the submarine, the load, the total number of torpedoes and endurance, will be greatly improved.

After carefully analyzing the performance of this drawing, Tirpitz mainly asked about the authenticity, heavy diesel engines, Germany is one of the pioneers, according to what they know, Britain is not faster than them, at most between the best, maybe Germany is a little ahead, where did this drawing come from, if it is obtained from Britain, we must also be vigilant about Britain's strength, God knows if he will also have submarines, according to the information they got before, even if Britain has submarines, it is only for research submarines, I'm afraid it's not as good as Germany's U2.

Soon, the person in charge of contact fed back the news, this diesel engine is made in the northwest, and the researcher who is studying the diesel engine was immediately shocked, almost silently called out that this is impossible, as the German diesel engine field, the strongest few people, they are quite recognized for their own strength, what is the place in the northwest, that is part of the Qing country, a poor and white Qing state-owned industry, not to mention such a cutting-edge machinery, this is the submarine power room, dozens of researchers, it took a few years, None of the achievements have been completed, and now it is completed by the Northwest of the Far East.

But the facts are in front of us, at this time, on the Berlin construction site that has started, there are several large machines temporarily produced by Yang Yuanzhao, bulldozers, road rollers, excavators, such huge machinery, each of which has infinite power, and when Yang Yuanzhao told the contact personnel that these are diesel power, and they can send people, everyone stopped talking.

Diesel engines are known for being bulky, they can even design a 2000 horsepower, or even larger diesel engine, but that volume, even on the battleship can not be loaded, too huge, the diesel engine itself is synonymous with bulkiness, but this seems to be huge, but only on land, to the sea is not as good as a small sailing ship, with diesel to propulse, it shows that the Northwest can make the diesel engine quite small, just this point, it can be proved that the Northwest in the field of diesel engines, has surpassed Germany.

The Germans, rigorous, pragmatic, in the face of the facts, knew that they were backward, did not complain anything, directly recognized the strength of the northwest, especially after Yang Yuanzhao showed some engine drawings, the premise of cooperation was also there, the Ministry of Foreign Affairs knew that it was not the British drawings, and even Yang Yuanzhao was assured that Britain had not even carried out research on large diesel engines, and their biggest enemy was the United Kingdom, and the intelligence about Britain was the top priority, Now it is only a breakthrough in the Northwest, and the Northwest has close relations with Germany, so it is not them who intervene, but directly handed over to the Admiralty and the Ship Design Bureau.

In a friendly and intense atmosphere, they began another negotiation, and in the end, Yang Yuanzhao paid the price of drawings, obtained the drawings of all the submarines currently in service and under construction, and when Germany helped the Northwest to build the Qingdao Shipyard, he would assist several submarine designers and professional engineers and workers to help the Northwest form a submarine production capacity, and let the Northwest participate in the design of the new class of submarines, and once the research is successful, the Northwest can be authorized to produce.

The conditions of the submarine are even more helpful than the previous battleship cooperation, after all, the battleship represents the pinnacle of a country's industry, whether it is from the power, from the hull, or even from the ship's guns, but the submarine is not so high, to put it bluntly, it is just a thing of a sudden cold arrow, as far as he is concerned, the technical content is not high, in addition to the engine and battery, the rest is at best three or four times the technical content of its own weight, 15,000 tons of dreadnoughts have helped the northwest to build, although it is under the huge interests, such a small ship of several thousand tons, what is unwilling, in the eyes of Tirpitz and Wilhelm II, the northwest is an object that can be fought for, armed with the northwest, and the relationship with the northwest is gradually approaching, pulling the northwest into the Allies, which is a powerful guy in the army, which is a real interest for Germany, as for the navy, just look at the United States and Russia, you will know that the same has enough tonnage of warships, with production capacity, But what about the combat effectiveness, the latter's Russia, even under absolute superiority, lost to Japan, how can Russia and the United States be considered maritime powers, and once had a history of navy, but what does China have, after 1894, does he still have a navy, just with those small boats and sailboards?

An engine drawing as a link, Germany will directly help the northwest to have a submarine force, which more or less exceeded Yang Yuanzhao's expectations, and also made him clearly understand the status of submarines in this world. Even a strategic expert like Tirpitz only sees the role of the submarine, but does not know that when the submarine's capability reaches a certain level, it can even play the role of a capital ship. Germany is so generous, he is not polite, with the help of Germany's strength to lay the foundation for submarines, as for the future, submarines are definitely not weaker than aircraft and warships Another important development direction.
