Approved the price, write it down and talk about it, although the reconnaissance aircraft is very good, Germany does not have the previous big money, the number of 500 has been reduced to 120, the army will be equipped with 50, the navy will be equipped with 70, so of course it is impossible to fully meet the needs, but the investment of almost 20 million is almost the investment of a battleship.

Two large orders, submarines are almost 300 million US dollars, and aircraft are more than 20 million US dollars, with these two, it will have a huge promotion of Germany's strategic intentions, after seeing China's strong scientific and technological level, Germany is a little helpless, surpassed by his own little brother, which has to be said to be the sadness of the boss, next, even in the most severe war environment, we must also strengthen investment in science and technology, subject to the feeling of others, is not willing to accept by everyone, As long as they make breakthroughs in certain areas, similar huge orders will not appear, and even if they do, the cost will be much smaller.

Next, what Germany wants to talk to China is the follow-up things, in part of the cooperation between Germany and China, there is a transfer of goods and technology, Germany was so to China back then, but I didn't expect that China took a few years, it will be blue, and now, Germany needs to take China's step.

Technology transfer, this is the only way to improve its own science and technology, of course, the Chinese side also knows, huge orders, must include this, just like the previous transfer, after a certain amount, it is necessary to take out the technology, signed a huge order, are close to 400 million US dollars, China will of course come up with part of the technology, but the specific one, you need to consider, it is impossible for Germany to give which, where did China get the technology from Germany, but also only less important technology.

The vision of German experts is quite vicious, and the first technology required is the formulation and production authorization of aluminum alloy, and the technology and production authorization of aero engines. Among the orders placed by Germany, a larger number are submarines, although the technology of submarines is excellent, and even the unique shell technology makes the Germans shine, but there is no major breakthrough, the Germans just can't produce the premise that they ordered it in China. In terms of the technical level of the product, the technology of the Air Force is higher than that of submarines, and submarines are just the integration of some projects.

After getting Germany's initial intentions, the Chinese side immediately gave the reaction aluminum alloy impossible, which is related to the aviation industry of the general thing, alloy field, perhaps this aluminum alloy, is just a very common light aluminum alloy in later generations, not a technical content of things, but these things, is the most non-transferable, material technology is technology technology, the emergence of each material, is accompanied by a large number of experiments, consumption, and even time, it can be said that in the field of science and technology, the most difficult is the alloy, in addition to luck, You can only rely on the massive ratio and time, slowly looking for alloys, and even sometimes, because of the lack of understanding of alloys, you will even miss some excellent alloys, and the waste alloys that were originally generated by research in a certain field may be the magic alloys in another field, which abound in the history of later generations.

The reason is very simple, the investment in materials is very huge, just according to a reasonable formula, to make a series of alloy products, as long as it does not meet the performance of this aspect, put aside, it is impossible to test the performance of this failure in an all-round way, after all, the performance of materials is very numerous, specific materials have specific uses, to test the performance one by one, maybe the cost will be unbearable, unless it is some materials that are close to success, or a very good material in a certain aspect, Researchers will delve into the mechanism and performance, and some of the poor performance, or obviously very poor, will not be able to expend resources to determine their characteristics.

This is also common in the field of materials science research, in later generations, there are even special failures in the development of materials, this kind of development is not every development, only there are choices, or there are goals, and only China, after having such an all-in-one machine, every accidentally obtained material, will be perfectly scanned, countless properties are shown, each waste material, there are at least 180 major items, at least more than 500 different performance indicators, the degree of detail is high, It is higher than the material that was the focus of later generations.

Because of this, China in materials science, has been innovative, the speed of development is not much better than the era of modernization in later generations, 10,000 material formulas per day, this is Yang Yuanzhao's necessary homework, and materials researchers, in a huge number of materials, experimental performance, etc., gradually find the law, form a basic rule, and then feedback to Yang Yuanzhao here, and finally increase the foundation of materials science, the two complement each other, China in the progress of materials science is quite fierce.

Similar to the aluminum alloy used in reconnaissance aircraft, it is already the most primary, and now most of the aluminum alloys used in Chinese aircraft are third-generation aluminum alloys, which are not only lighter in weight, but also more outstanding in performance, and have derived at least a dozen systems, especially those used in the engine, high-temperature and high-pressure alloys, which make the performance of the engine improve to a greater extent.

China has made great progress in materials science, but materials are always the core of a country, the most basic aluminum alloy, China will not authorize, which will save Germany at least 10 years, or even 15 years on aluminum alloy, this is the core secret, it is impossible.

The Chinese side did not have any mud and water, directly informed Germany of this result, the German side also knew, he just gave it a try, before in the cannon steel, there was a encounter with China in the production of 15-inch naval guns, Germany wanted technical information, but was rejected by China, until now, just export the barrel, now aluminum alloy is like this, there is a precedent, of course Germany will not turn its face, their purpose is not actually this, for the Air Force has no idea of Germany, I didn't realize the important role of aluminum alloy, but if there were, under the premise that the cost was reduced to a considerable extent, there were still ways to apply this application, such as the weight reduction of the battleship, although the use of lightweight wood interior could further reduce the weight of the battleship, but this reduction had a good effect on the promotion of the battleship, but unfortunately it could not be transferred.

Germany's core requirements are not aluminum alloy, although this is also very important, but compared with the power system, it is still a little worse, in this era, power is the foundation, whether it is a warship, or an aircraft, without enough power, can not get excellent performance, China's previous power, let the fantasy class, a huge warship of nearly 50,000 tons, have abundant performance.

Now, as far as the submarine is concerned, China's power field is even better, as for the aircraft, it proves that in the small horsepower engine, China's miniature advantage, a small aircraft, equipped with a 1500 horsepower engine, this is not an engine that Germany can't make, but to make such a small, such a high thrust-to-weight ratio, it is almost impossible.

This time, Germany had a big idea, and did not directly ask for the original engine units of submarines and airplanes, but only asked the Chinese side to support them in many fields such as marines, motor vehicles, and internal combustion engines.

Slap in the face, give a sweet date, in terms of aluminum alloy, refuse without hesitation, but in the field of power, it is not easy to refuse, Germany does not want the most advanced, but only asks China to help Germany establish an engine system.

The engine is also very important, whether it is flying in the sky, running on the ground, swimming in the water, it has a lot to do with the engine, whether it is a battleship, an airplane, or a tank, one of the most important cores is the engine, a powerful engine, can make a second-rate design burst out of dazzling brilliance, but a weak engine, enough to make a first-class design become a second-rate.

Whether to popularize it for Germany has become a huge problem on China's side, but in the end, China still decided to let go, power is China's most powerful place, China in addition to giving incomplete versions of aircraft and submarine engines, but also provide a lot of other technologies, these may be very important to Germany, enough for Germany to upgrade more than two grades in the field of power, but can not shake China's lead.

China has been promoted to a considerable degree in the field of power, the most important thing is that China only gives the engine information, which is complete, without a little bit of wrong information, but there are reservations in the material, only for the requirements of the material, the data, these are detailed to the extreme, but there is no production and refining method of these materials, just such a point, the German side wants to complete the transformation and production, there is no 5 years of time, don't think, even after 5 years, whether it can achieve complete quality, it is also very difficult.

After the order of aircraft and submarines, Germany signed a large order with China, 200 million US dollars of various engine orders, including almost 100 to 10,000 engines of various types, which is the necessary investment in engine technology, only the delivery of these, is the investment and guidance of technology, which is also necessary to obtain technology.

In the time of Deng Jieqian's rest, Germany and China had close contacts, reached a series of military cooperation of more than 600 million US dollars, and Germany obtained key engine technology, which to a certain extent, made up for Germany's shortcomings, in 1916, in the face of the sudden appearance of Britain and France, when the sharp weapon of trench warfare was cracked, it quickly kept up, manufactured Europe's first-class tanks and armored vehicles, and continued to maintain an advantage in the army.

The German side is jubilant, the appearance of Chinese submarines has solved the most critical breach of diplomatic relations, and a large amount of technical cooperation will make Germany's military field to a higher level, but on the side of the Entente, it is gloomy, and the news that a large number of merchant ships have been sunk has still reached the side of the Entente.
