As the leader of the Northwest scientific community, to a certain extent, he needs to guide the Yinshan base, although when he was in Baotou, he gave some things, but those things are relatively vague, and he must understand the progress of science and technology now, and issue updated guidance.

The progress of science and technology cannot be false, Yang Yuanzhao still had some mistakes in pointing out before, and after he found some misunderstandings in research projects, he pointed them out in time to turn them to a more suitable direction.

Truss also knows that the two projects he is responsible for, although they are both steam turbines, one is obvious, it is for military use, and the other is for civilian use, in terms of height, the critical generator set project, obviously, has a higher scientific and technological content, but what is more important for the northwest is another project, the marine steam turbine project, which is obviously the unit on a large ship, which can be used on commercial ships and other ship projects.

In the critical project, after some gains and experiences, Truss came to the marine steam turbine, thinking that it might be two projects of the same system, but when he really saw the marine steam turbine, he found that there were the same places and different places in it.

The biggest change is the addition of a turbofan that absorbs heat energy to the steam turbine, the theory of the turbofan that has never appeared, is listed there, although it is only a simple theory, but with the strength of Truss, it is easy to see the correctness of this theory, itself for the steam turbine. Part of the power is wasted, the hot gas generated by the turbine. It can only be recycled physically, and the effect is not good.

But the turbofan theory. However, it has found another way, reducing the consumption of hot gas and increasing the overall power, although it is not as critical as the critical state, but the marine steam turbine, unlike the steam turbine used in large factories or power plants, is limited in size, and it is impossible to put huge recovery and critical equipment. On the contrary, it is a small turbofan, which is more suitable. The use of turbofans further improves the energy efficiency ratio of the turbine.

However, the keen Truss still found that there are several problems that must be solved in order to use turbofans, and compared to the critical, some non-metallic materials or thermal insulation materials can be used for construction, and the volume of the ship is smaller. The place where the power unit is placed is relatively limited, so most of it is metal, high temperature and high pressure steam, and the strength requirements for metal materials are very huge. It's not easy to solve the material.

In Truss's view, the solution to this problem may be more difficult than that of critical generator sets. Materials science, especially materials at high temperatures and pressures. The difficulty of this in itself is a worldwide problem. Regarding power, about the use of materials, many theories are ahead of their time, beyond this era, just Truss knows, there are many.

But after reading the records in the laboratory, Truss knew that he was wrong, the Northwest didn't know what was going on, and there were at least 10 kinds of alternative materials that came out, and the processing capacity and integration ability were far beyond Truss's imagination, that is to say, the biggest problem of this power unit has actually been solved, and the rest is how to use genius creativity to use this material.

Seeing this, Truss even felt that in the short term, this project could be broken through, and he even burst out with more vigorous energy than the previous critical engine project, and in just three days, several sets of plans were designed.

After handing over the follow-up work to the assistant, returning to the critical laboratory by himself, and continuing the research of critical experiments, he thought that these things were enough to keep the laboratory busy for several months, because he knew that even if there were materials, processing technology, production methods, even if it was the production of the laboratory, there was a long way to go, and it was not simple to complete.

The development of things once again shocked Truss, in less than a week, in the laboratory, according to the plan he designed, 3 different kinds of objects were taken out, compared with the 5 plans he designed, it was not particularly perfect, but this speed shocked him.

Truss is a theoretical researcher, but also involved in practicality, processing does not know much, before in the outside laboratory, the northwest processing capacity, is only the tip of the iceberg, in the Yin Mountain base, huge support, the top workers, only the national treasure level 8 workers, there are as many as 300 people, the northwest spent five or six years, training the world's largest group of industrial workers, the wisdom of the Chinese, the foreign movement and the heritage of opening eyes to the world, under the huge financial support of the northwest, A different spark burst out.

Northwest incomparably strong processing capabilities, to solve Truss's biggest shortcomings, and introduced him into the large-scale steam turbine research, his genius ideas suddenly came out like a spring, some mistakes, may look very beautiful design, can be quickly produced, and then in accordance with the inherent mode of experiments, some simulation experiments, even more suitable than the practicality of the ship, the miniaturization and promotion of large steam turbines for ships, step by step, faster and faster.

In just 2 months, in theory, at least 6 kinds of large steam turbines have been theoretically determined, and the entire horsepower has been increased by 80% compared to the previous one, and the volume and weight have been reduced to varying degrees, which means that if the new steam turbine system is used, the entire power system will increase by 80%, which can push more tonnage warships and obtain greater speed.

It is conservatively estimated that the tonnage of the future warship can be expanded to more than 70,000 tons, and the speed will still maintain the speed of the fantasy level, and even increase. In the artillery laboratory, the research on 405 mm, or even 461 mm, that is, 16 inches and 18 inches and above, has gradually entered the formal, according to the schedule, 16 inches can be seen in kind this year, 18 inches for a maximum of 3 years. It was also possible to study successfully, the study of a new generation of battleships. It started to be on the agenda.

The Admiralty was thrilled, all the time. Even if it is the Fantasy class, in their opinion, it is just a warship to catch up with the world's advanced warships, because the specific data of the new generation of British warships has not been detected by Germany, so in the navy, they do not realize at all that the Fantasy class has become the most powerful warship in the world. However, if a super battleship is developed based on 16-inch or even 18-inch guns, with a tonnage of more than 70,000 tons, it must be the world's first without exception.

The Naval Laboratory was excited. Proposed a shipbuilding plan for the next 5 years, and sought the support of the Yinshan base, this plan condensed the efforts of the navy and took the fastest time. It was sent to Yang Yuanzhao here, and I wanted to come, with Yang Yuanzhao's support for the navy. It was not difficult to realize this plan, but I didn't expect it. Here in Yang Yuanzhao, he was rejected. Yang Yuanzhao bluntly rejected the plan.

The reason for the veto is very simple, not practical, in Yang Yuanzhao's cognition, the 15-inch fantasy class is for the present, and even in the future, to provide fire support and air protection for the task force, and to provide artillery support for landing operations, which is enough, and the reason why he really studied this large steam turbine crew is not for battleships, but for aircraft carriers.

Yang Yuanzhao, who came from later generations, is very clear about the inevitability of aircraft carriers replacing battleships, battleships because of their own tonnage, and even scientific and technological reasons, it is impossible to enlarge to 100,000 tons, or even more than 200,000 tons, the increase in attack power will form a curve, to 50,000 tons, the combat effectiveness curve of the battleship, in fact, the increase has reached the limit, from 50,000 tons to 70,000 tons, although 70,000 tons of battleships can easily defeat 50,000 tons of battleships, but the increased strength may not be compared according to tonnage, Just a little bit stronger.

Among the battleships, a little improvement may bring revolutionary consequences, the emergence of the dreadnought, the former dreadnoughts are all sent to the garbage heap, does it really mean that the dreadnoughts are much stronger than the former dreadnoughts, in fact, all aspects are only a little improved, only in the firepower, but this improvement has a certain strength, for example, if the former dreadnoughts are equipped with the latest armor in the northwest, when the dreadnought's guns cannot pass through the main equipment of the former dreadnoughts, The former dreadnought also has the possibility of fighting the dreadnought.

Yang Yuanzhao knows very well that the combat capability of the aircraft carrier is not in the aircraft carrier itself, the speed, protection, and even the capacity of the carrier-based aircraft have a limit, but the strength of the carrier-based aircraft has no limit, and he knows very well how powerful the carrier-based opportunities will be in the future, over-the-horizon, precision strikes, and more powerful bombing capabilities, which will provide sufficient lethality for the aircraft carrier.

The study of power crews, from the very beginning, was not intended for battleships, but for aircraft carriers. Speed, perhaps for battleships, is only one aspect, one of the three principles, but for aircraft carriers, it is extremely important, it is necessary to ensure that aircraft carriers have sufficient speed, at least not worse than battle cruisers, a carrier that can accommodate 80-100 carrier-based aircraft, loaded with a large number of materials and bombs, in addition to anti-aircraft fire, it is impossible to arrange other artillery fire, otherwise this is a four-like.

The speed does not come up, such as a lower speed, at most it can only become an escort aircraft carrier, escorting the merchant formation, the real main aircraft carrier, must have enough speed, and do not provide firepower, if you really want to protect the firepower, as long as the escort battleship is good, the battleship from a main battle capital ship, into a frigate, and even in the future, with the deepening of the study of aircraft carriers, the battleships themselves will be eliminated, replaced by large air defense frigates, and the concentrated strike capabilities of battleships, All on top of carrier-based aircraft.

The solution of the power system is equivalent to a package of projects, the improved model of the fantasy class, because of Yang Yuanzhao's veto, only 4 will be built, which will be used as the flagship of the core warship, while the aircraft carrier, which can be almost infinite, is planned to build at least 8 ships, which is equivalent to 2 ships in a fleet, and the improved model of the fantasy class will be matched together to form the main body of the 4 major task forces in the future.

The current Northwest is different from before 1908, and also different from a year or two ago, the strong Northwest is developing rapidly and rapidly almost every day, and the designers have their own unique aspects of the design of warships after absorbing the careful teaching of Germany.

Yang Yuanzhao came from later generations, the computer-aided design of later generations has been very mature, this era, has not yet developed to this point, model, simulation of the ocean, simulation of the hydrological environment, these can promote the design of warships, do not need to directly produce huge warships, just from the extremely high precision model, under the specific calculation, the simulated pool, can allow a certain proportion of warships, obtain enough data, these data, reverse the design of the ship, some fluid mechanics, hydraulics, The study of the design of the battleship and other aspects can be passed

Powerful battleships will play a smaller and smaller role in the future, perhaps only in this battle, maybe when the Northwest shows the power of aircraft, the whole world will accelerate into the era of aircraft carriers, even the lowest-level escort aircraft carriers, as long as the number reaches a certain level of premise, it is terrible enough.

The Northwest Navy headed by Yang Yuanzhao knows very well that escort aircraft carriers are really nothing, and the reason why they are called escorts is because they do not play much role in the main battle, and only the aircraft carriers are useful in the main battle.

There is no other reason, speed, aircraft carriers, have faster speed than battleships, the main aircraft carriers during World War II, the speed is more than 30 knots, and the multi-deck arrangement can project more aircraft in a short period of time, the steam catapult has no way to equip the premise, the northwest can only refer to the jump deck of the Soviet Union in the future, and the powerful power mechanism can not only push the speed of the aircraft carrier to a higher level, but also can create a larger aircraft carrier.

In later generations, the displacement of aircraft carriers gradually increased, but carrier-based aircraft are becoming fewer and fewer, that is due to the continuous improvement of the performance of fighters, the difference between carrier-based aircraft, so that the number of carrier-based aircraft, may not become the basis for measuring the strength of aircraft carriers, the huge body of aircraft carriers, but will become the most important maritime combat platform, under the premise that joining the First World War is a foregone conclusion, in the vast Pacific Ocean to compete with the United States, aircraft carriers have become a killer feature to break through the number of battleships, and will also create difficulties for the United States and Britain to follow up. Aircraft carriers are not just ordinary modifications, the design concept has gone through the next 20 years in World War I and World War II, which requires them to continue to suffer losses before they can learn, and time becomes the key, when a large number of battleships are sent to the bottom of the sea, and new warships have not yet been put into service, the war has effectively ended.
