Iron Sonata of World War II

The core of Haushofer's theory is the theory of "living space". In his view, the country is an organism, and expanding the living space is the instinctive pursuit of this organism.Haushofer believes that the future world will be composed of four pan-regions dominated by four major powers: the Pan-American area dominated by the United States, the Pan-Asian area dominated by Japan, the Pan-European African continent dominated by Germany, and the Pan-Asian area dominated by Japan. The pan-Russian zone dominated by the Soviet Union.Then Germany should control Pan-America and Pan-Russia on the basis of dominating the Pan-European African continent.The subsequent military operations of Nazi Germany were almost the practice of Professor Haushofer's theoretical line.

As I said before, it is almost impossible for a land-sea complex country to support expansion in both land and sea directions at the same time.The biggest problem with Professor Haushofer's theory is that he overestimated the limits of Germany's national strength as a land-sea complex and underestimated the war potential of the United States and the Soviet Union.

Although Helena knew that Haushofer's theory had no possibility of realization, Helena introduced herself together with Hitler and Hess.

Professor Haushofer was also quite surprised to meet the daughter of the commander of the Wehrmacht here. After the four of them sat down around the table, Helena started the conversation, "Professor Haushofer, it's an honor to be here. I met you, and my father and I appreciate your research results on geopolitics at the University of Munich." In order not to talk to death directly, Helena can't directly deny Professor Haushofer's Theory, I still appreciate Professor Haushofer's theory. In fact, Professor Haushofer's theory that the country is regarded as a living organism is still very reasonable. What is wrong is the prescription he gave to Germany.Geopolitical scientists of later generations always scolded Professor Haushofer while unconsciously being influenced by Haushofer.

Hitler and Hess were also believers in Professor Haushofer's theory, and the four of them seemed to find a point of agreement at once.Hess spread out a world map stacked at the corner of the table on the table, and the four of them immediately began to point out the country on the world map with great interest, which was a bit like Zhao Kuo talking on paper.

Chapter 25 Integration Efficiency

Although Professor Haushofer is the godfather of Nazi geopolitical theory, and although the geopolitical blueprints of Hitler and Hess have no differences in principle with Haushofer, in terms of specific means of realization, the opinions of the two sides differ. Still something different.

The biggest difference is that Professor Haushofer advocated fighting for the Soviet Union politically, and established a four-nation alliance composed of Germany, Italy, the Soviet Union, and Japan to jointly oppose the maritime hegemony of Britain and the United States.Hitler and Hess believed that Germany should strive to reach a settlement with Britain and the United States and jointly deal with the polar bear of the Soviet Union.

Of course, the historical facts of the previous plane have proved that no matter which side of their point of view, there is no possibility of realization.Because unless they are defeated militarily, neither the Soviet Union nor Britain and the United States will agree to form an alliance system with Germany as the leader and themselves as the second.

Seeing that the three uncles were about to start arguing for the nth time about whether Germany should unite with Britain and the United States or unite with the Soviet Union, Helena put on a small face on the surface and listened with gusto, but in her heart she began to complain wildly: uniting with Britain or the Soviet Union is not the point at all OK!The key is the contradiction between the unlimited strategic goals pursued by Germany, the limitation of Germany's comprehensive national strength, and the dilemma of Germany's geographical conditions. ! !

But can Helena directly persuade the three uncles to give up their infinite goal of dominating the world?Obviously impossible, these three guys are all hardcore nationalists, and they are also particularly fanatical, extreme, and paranoid!Not to mention the mustache, Hess was still swearing allegiance to Hitler in the post-war trial seat, and was sentenced to life imprisonment; although Haushofer was exempted from trial after the war, he committed suicide by taking poison and was given to the third party. The empire was buried with him.

It is impossible for the three of them to give up their goal of dominating the world directly, but it does not mean that Helena can do nothing, so the three uncles who were about to start a new round of argument heard a child's voice say: "In the end, we are discussing whether to unite the United Kingdom and the United States." Before the problem of uniting the Soviet Union, can you answer me a question first?"

The three uncles were taken aback for a moment, but Mustache quickly realized: "Of course, cute little angel."

Helena nodded to Mustache and said: "We know that the population of Germans living in central Europe is only about 100 million people. German civilization-influenced areas such as Slovenia are included in the empire's territory, and the land area of ​​Germany is less than [-] million square kilometers, and the local population is only a little over [-] million."

Helena paused, and then continued: "Professor Haushofer, Mr. Hitler, Mr. Hess, you hope to establish a pan-European African region dominated by Germany. Then rely on this, and the pan-European African region dominated by the Soviet Union. The Russian zone and the US-dominated Pan-American zone cooperate or compete. Is this the case?"

Seeing the three nodding, Helena also smiled back: "This is the problem we need to face next. If we can control the pan-European and African regions as envisioned, can we compete with the Soviet Union and the United States in the future?" I think it largely depends on the integration efficiency of the resources, population, and industrial production capacity of the three countries in the areas under their control!"

"This is the question I want to ask. The population of Germany is only 100 million, and the area of ​​ethnic settlements is less than [-] million square kilometers. How can we ensure that Germany's resource integration efficiency in pan-European and African regions is higher than that of its opponents?" Helen Na throws the last question.

The relaxed expressions on the faces of Haushofer, Hitler, and Hess disappeared, replaced by dignified expressions. This is indeed a question that they have not studied carefully before.

"If we can't find a way to efficiently integrate the resources of the Pan-European and African regions, especially the resources of non-German settlements, there will be no living space for Germany! If the United States and the Soviet Union can integrate their internal resources more efficiently than ours , we will be at a disadvantage in the competition, and even squeezed and collapsed on the two fronts of Britain, the United States and the Soviet Union!" Helena finally made up for the three silent uncles.

Seeing that the three uncles who were still happily discussing how Germany would rule the world seemed to have all their strength taken away at this moment, Helena was still a little proud, and followed the routine of reading "Warring States Policy" in her previous life Well, when strategists lobby the monarch, they always exaggerate the danger before prescribing the medicine. Moreover, Helena feels that what she said before is not alarmist, which has been confirmed by the history of the previous plane.

When it was time to prescribe the medicine, Helena said, "Area and population are indeed our disadvantages in integrating resources in the region, but I don't think this problem is unsolvable."

Seeing the three uncles listening carefully, Helena knew that they no longer regarded themselves as a ten-year-old loli, but as friends who could discuss international affairs on an equal footing. She couldn't help thinking: "Warring States Policy "Honestly don't deceive me!

Clearing her throat, Helena went on to say, "Integrating the entire pan-European African region, we only need three things: a stick, a carrot, and a flag."

"It goes without saying that a country's international prestige is inseparable from strong force. The so-called prestige is the credibility of deterrence. Therefore, getting rid of the shackles of the "Treaty of Versailles" and rebuilding a strong force is a prerequisite for Germany's overall revival. It is also the most basic condition!"

"Carrots are interests. If a country wants to maintain internal stability, it must rely on interests to induce people and rely on harm to restrain people. It is the same externally. But who to give carrots to, how to give, how much to give, and how to tie carrots to Pan-European African regions other peoples, and their willingness to serve the interests of Germany is a matter for discussion."

"Here I have a little immature idea, which can be used as a reference for three people: Germany can consider restructuring the industrial chain in the pan-European and African regions at the right time, and form it in the manufacturing field: Germany—other Western European countries— Eastern European countries—the industrial geese in Africa and the Middle East. Germany masters the core technology and is responsible for the final integration of the industrial chain, ranking first in the geese; other Western European countries are responsible for providing high-end spare parts for Germany; Eastern Europe takes advantage of labor cost advantages to be responsible for labor-intensive products Africa and the Middle East are responsible for providing raw materials.” Helena directly moved out of the geese pattern of industrial chain transfer in the Asia-Pacific region in the 80s and 90s: “Although all countries in the geese can benefit from the division of labor and cooperation, Germany can Backward industries in China are transferred to other countries in turn, and they focus on industrial chain integration and cutting-edge technology development. Because Germany has excess profits from high-tech products, coupled with the advantages of the final integration of industrial chains, theoretically speaking, other countries will always be Germany's part-time workers Aberdeen. So Germany will always benefit the most.”

"However, it must be noted that there must be no second country with a complete manufacturing industry chain in the region, because once a country has a complete industrial chain, it will have the ability to upgrade its own industries. Therefore, we must let The industrial chains of other countries are fragmented and flattened. They cannot survive without Germany!" Considering the counterattack case of the later Republic in the integration of the Asia-Pacific industrial chain, Helena added.

It is true that Helena has never eaten pork, but Helena has seen pigs running, and the three uncles were immediately fascinated by this economic model that transcended the times. "Quickly, write this down." Mustache told Hess while urging Helena to continue.

"The flag is ideology." Helena said with a smile: "Mr. Hitler, your National Socialist theory is very eye-catching. I believe that Mr. Future's ideas can help Germany to glory. But I think it can be further expanded , let the idea of ​​national socialism not only belong to the German nation, but also belong to the whole world!"

"This brand-new ideology is not only different from Soviet-style communism, but also different from Anglo-American liberalism. By promoting Mr.'s ideas to other nations in the Pan-European African region, not only can other nations be more closely united in Germany surroundings, and can open up a new front to compete with Britain, the United States, and the Soviet Union!"

"In short, we should use sticks to make others fear us, use carrots to make others rely on us, and use flags to make others yearn for us. If we can do these three things, I think Germany can overcome the disadvantages of population and area to a large extent. To catch up with the United States and the Soviet Union in the efficiency of internal resource integration, at this time, whether you choose competition or cooperation, you can deal with it calmly," Helena made the final conclusion.

Helena looked at Mustache, only to see something called "ambition" burning in his eagle-like eyes again.Hess and Haushofer were also in a state of extreme excitement.

"That's great, what Germany needs to do is to be the leading goose of Europe, the standard-bearer of national socialism, and the center of the world!" Mustache stood up excitedly, held Helena's hand tightly and said: "My friend Helena , now, you are our comrade!"

Mustache, have you watched "The Three-Body Problem" too much?Who are you gay?Don't you think it's impolite for an uncle like you to hold a little loli's hand like this?Helena thought.

However, in order to build a good relationship with the future head of state, Helena still held Hitler's somewhat thin fingers, and said goodbye to the three uncles "reluctantly".

Judging from the reactions of the three people, Helena knew that her words should have played some role. Although the narrow nationalist tendencies of the three people could not be changed, if she could make Germany's future policies less blunt tactically, it would be considered A change for the better.Under the circumstances that the nationalist forces could not be prevented from coming to power in Germany, Helena could only comfort herself in this way.

The author has something to say: After a few more years, the protagonist will be able to climb the technology tree with all his strength.

Chapter 26 Steel Core Bullets

After "reluctantly" bidding farewell to the three mustaches, Helena walked out of the Randsburg Fort Prison, took a deep breath of fresh air, wiped the sweat that did not exist on her head with her hands, and muttered to herself. Yu said: "Sure enough, it is more suitable for me to play micro-manipulation in the field of equipment technology. Talking about international strategies with these figures who shake the direction of human history makes me feel a lot of pressure!"

Helena is a man of action, and soon she got on the train to Württemberg, preparing to start her own new round of "micro-operations" in the field of firearms.This time Helena's destination is the gun factory of Mauser in Württemberg.If Helena's prediction is correct, the steel-core bullet commissioned by Mauser some time ago should be time to produce results.

In this era, the structure of bullets is mostly like this: the outside of the bullet is wrapped with copper armor, and the inside of the bullet is filled with lead, which is the so-called "lead core bullet".Lead-core bullets have a high density of warheads and good long-distance energy storage. The soft lead core can also reduce the wear of the bullets on the rifling of the gun. Therefore, during the two world wars, lead-core bullets were the mainstream structure of bullets.

But lead-core bullets also have their own shortcomings. There are two main shortcomings: the first is that the core is too soft and the penetration is insufficient; the second is that lead, as a non-ferrous metal, is relatively expensive.Although each bullet consumes very little lead, due to the astonishing consumption of bullets in wars, the accumulated lead consumption is very considerable.

Since lead core bullets have these shortcomings, humans will naturally come up with corresponding solutions.In the previous plane, Germany, which lacked non-ferrous metals, began to produce a "semi-armor-piercing bullet" after 1941. The so-called "semi-armor-piercing bullet" was actually the so-called "steel core bullet" in later generations.The innermost core of the steel core bullet is a steel column, and the outer armor is still made of copper. A layer of lead sleeve is filled between the steel column bullet core and the armor (mainly as a buffer to prevent the rifling from wearing out too quickly) .Form the so-called three-piece structure of "steel core lead sheath copper jacket".

Steel core ammunition is so classic that it has been the main ammunition for rifles in various countries from the post-war period until the 21st century.Since it is a classic, and it is not very difficult to realize, naturally it cannot escape Helena's plagiarism!Therefore, Mauser, who had been doing nothing after World War I and almost relied on selling shotguns for his livelihood, received Helena's technical cooperation invitation.

Now Helena's main purpose of going to Mauser's company is to visit Mauser's research and development results on steel core bombs.

When she came to the test range of the Mauser company, Helena was warmly received by the researchers, but when Helena proposed to test a few rounds with a Gew 98 rifle, she was "ruthlessly" rejected by the staff.After all, Helena is the daughter of the commander-in-chief of the army. If she accidentally misfired the gun, or hurt herself.I am afraid that the German Army's pitiful rifle orders every year will have to say goodbye to Mauser.

Helena regretted not being able to touch Gew 98 with her own hands, but soon regained her spirits.

What will be tested today are steel core bombs with three different structures.

The first type is the most conventional "steel core lead sheath copper jacket" steel core bullet.

The second type is a small change based on the first type. Its lead sheath does not completely fill the gap between the armor of the steel core, but leaves a gap behind the armor of the tip. A tiny cavity.

The third type uses a composite bullet core, the first half of which is a steel column, and the second half is a lead column.

如果有上一个位面的军迷在此，一定会认出第二种子弹的结构其实是参考了后世苏联规格为5.45x39mm的7N6枪弹（也是AK74的枪弹），第三种子弹则是参考了后世美国规格为5.56x45mm的M855枪弹（也是M16A2的枪弹）。

The three kinds of bullets were first tested for penetration, and the target boards used thin steel plates, pine boards and brick walls.After several rounds of gunshots, unexpectedly, the first type of bullet with the most traditional structure won the first place.

However, in the next round of lethality tests, the second and third schemes quickly saved face, this time shooting pork and agar (a vegetable glue, often used to simulate the human body).After the second bullet hit the target, the warhead deformed, causing the bullet to lose its stability and tumble in the pork and agar, causing huge trauma.The third type of bullet is even more extreme, and the composite core shatters under stress after hitting the target.

Imagine if the bullet was shot into the human body instead of pork or agar, then the rolling or breaking of the bullet would turn the organs in the human body upside down!

This result can't help but remind Helena of the famous "Dum bomb".

"Dum" is a bullet manufactured by the British at the Dum Arsenal in Calcutta in 1897. The copper jacket of the "Dum Bullet" does not completely cover the warhead, but exposes a part of the lead core in the middle, so after hitting the human body, the projectile body is very easy to shatter, causing very terrible trauma!However, the "Dum bomb" also has the disadvantages of poor storage speed and weak penetration ability.

Although dum bullets were banned due to "inhumanity", humans soon invented new types of bullets that can take into account penetrating power, storage capacity and lethality!From this point of view, it is completely impossible to rely on a treaty to restrict the racial talent of human beings in researching how to efficiently kill their own compatriots.

A second of silence was observed for the fate of human beings to kill each other, and Helena, who had a vehement mouth and a snake heart, began to devote herself wholeheartedly to the great cause of developing weapons that can kill and kill fellow human beings more efficiently.

Chapter 27 The Joke Tank

The Wehrmacht was very satisfied with Mauser's research results on steel core bombs.

However, to Helena's surprise, after some comparisons, the Wehrmacht finally chose neither the design of digging a cavity in the lead sleeve nor the design of a composite bullet core, but chose very "conservatively" The most orthodox steel core bullet is the traditional combination of steel core, lead sleeve and copper jacket.

With a lot of questions, Helena found her father, General Sektor, in this life.

"I knew it was you, a crazy girl, who was making trouble!" Sektor laughed loudly when he heard it, touched Helena's head and said, "No wonder my colleagues in the National Defense Forces were still complaining to me, saying that the Sektor family The little ghost is finally willing to contribute some genius ideas to the Army, and it turns out that it is about steel core bullets. You want to ask why the second and third designs are not used?"

Seeing Helena nodding wildly, Seckert went on to say: "It is a good design to dig out the cavity in the lead sleeve and use a composite bullet core, but it is not suitable for our large-scale equipment. First, compared with the simple steel core lead These two designs have higher requirements for the accuracy of bullet processing and assembly, which will waste a lot of processing man-hours for bullets with huge consumption; second, these two designs will move the center of gravity of bullets backward, which is harmful to the impact of bullet flight. Stability is disadvantageous, which has been proved by range tests; third, these two designs will weaken the armor-piercing ability of some bullets."

Sektor paused and said: "To sum it up: the production of ordinary steel core bombs is easier, the cost is lower, the flight is more stable, and the penetration power is stronger. Although the lethality is not as good as the other two designs, it is completely enough. use, which is why we chose it.”

Seeing Helena's slightly dejected look, General Seekert patted her on the shoulder and said, "The second and third designs can be used as technical reserves. The technicians of Mauser Company believe that if this design is used in On a bullet with a smaller caliber, the gain of the killing effect will be more obvious."

The reason why Helena was downcast was not because the second and third options were shot by her father.In fact, Helena blushed for her own sacrifice.

For a long time, Helena relied on her advantages as a traverser and always wanted to be a technical porter. The series of previous successes made Helena herself feel a little smug.On the issue of steel core bullets, Helena almost forgot: the bullet design that was suitable for the 70s-80s may not be suitable for the processing capabilities of the 20s-30s; it is suitable for small-caliber bullets (5.45mm and 5.56mm) The design may not be suitable for large and medium caliber bullets (compared with large and medium caliber bullets, designs such as lead sheath with cavity and composite bullet core have a better effect on the lethality gain of small caliber bullets).

"I've embarrassed the traverser." Helena thought ashamedly.

"Don't be discouraged, children. Even the performance of ordinary steel-core bullets is much better than the lead-core heavy-point bullets we use now. The National Defense Forces have decided to purchase a batch of steel-core bullets for the troops to try out. If the response is good, our rifles This type of ammunition will be used uniformly." Seekert's words interrupted Helena's self-blame.

It turns out that German rifle bullets in the first period were mainly heavy-duty pointed bullets with a lead core and copper armor. This bullet is characterized by a sharp head, a slender body, and a slightly smaller diameter at the tail of the body than the middle, and it is converged into a boat shape.

The heavy-pointed projectile is compared to the flat-bottomed and light-pointed projectile with a shorter body. Although the muzzle velocity of the heavy-pointed projectile is not as good as that of the light-pointed projectile, the body of the heavy-pointed projectile is heavier (the heavy-pointed projectile weighs about 12.8 grams, and the light-pointed projectile The bomb weighs about 10 grams), and the aerodynamic resistance is smaller, so the long-distance energy storage capacity is stronger.In the previous plane, at the beginning of World War II, the lead-core heavy-pointed bullets had completely replaced the light-pointed bullets and became the standard bullets for German rifles.

However, in this plane, lead core heavy point bullets may not have this opportunity.

The shape of the new steel-core bullet is basically the same as that of the old-fashioned heavy-point bullet, but the weight is not much heavier than the light-point bullet (because the density of the steel core is lower than that of lead), so the initial velocity is higher than that of the heavy-point bullet, and the trajectory is also flatter.Although the long-distance storage energy is inferior to the heavy-point bullet with a heavier warhead, the existence of the steel core makes the long-distance penetrating power of the new bullet stronger!

According to the official words of the Army Weapons Bureau, "the new bullet perfectly combines the advantages of the heavy-pointed bullet and the light-pointed bullet, and it also has stronger penetration than the lead-core bullet. !"

With the affirmation of her father Sektor, Helena, who was a little depressed just now, immediately revived with full blood!So Helena sat on her father's lap, took Sektor's hand, and coquettishly asked her father to tell her something new in the army.

General Sektor showed a loving expression on his face. He always had no resistance to the coquetry and cuteness of his only precious girl, so in order to make his daughter happy, General Sektor tried his best to mobilize his not-so-superb storytelling skills. Talent, began to tell: "There is one new thing in the army. You used the 'Peace Fund' to get some 'crawler transport vehicles' before, right?"

"Yeah, what's the matter?" Helena murmured in her heart: Doesn't this violate the Treaty of Versailles?

"After Mann Co. developed the prototype vehicle, the sales in the civilian market were not very satisfactory, so they sold a batch at a very low price to the army for trial use. The army also felt that the cost of using crawler transport vehicles was relatively high, so they quickly sold them These tracked transport vehicles were idle in the garage of the transport department. As a result, these vehicles were smashed out by a captain of the transport department. He asked the soldiers to paste these tracked transport vehicles with wooden boards and paper shells to make them look like tanks. , go out and do some 'pull training'."

Seeing that Helena listened with gusto, Seckert went on to say: "The number of 'pull training' has attracted the attention of the French. The French have accused us of secretly equipping tanks through the 'Allied Powers Supervisory Committee' and issued an investigation report to us. Request. Not to mention, the captain and the group of soldiers really did a good job of manual labor. It’s really like putting a wooden shell on the tracked transport vehicle. The body, painting, and turret are made vividly, not close It looks exactly like a real tank. When the French investigators came to have a look, they found that the so-called 'tank' was just a tracked vehicle covered with a wooden shell, and even the so-called 'barrel' was just a wooden stick. I can't stand up straight."

This captain is a talent, don't let it go to waste, Helena thought to herself, so Helena asked her father cautiously: "What's the name of the captain of the transportation department?"

Seekert tried hard to retrieve the memory in his mind before replying: "It seems that the surname is Guderian. I heard that Captain Guderian who is now driving a wooden 'tank' for exercises has become a joke for the French after dinner. .”

Helena: "..."

Chapter 28 The Name of the Swan

Although Helena quickly confirmed that the captain of the logistics department was the future German "father of blitzkrieg"-Heinz William Guderian.However, Helena is more patient than most traversers, and she is not going to take a look at Guderian's fate at this point in time.

In Helena's memory, Guderian's experience in the transportation department was precisely the critical period in the formation of his mechanized warfare theory. Helena did not want to bring variables to Guderian's theoretical research because of her own uncertain factors. .As for the future, gold will always shine. When Guderian's theory is more mature, it's not too late to communicate, Helena thought.

……

In 1925, two major events occurred in Germany:

One is that Hindenburg succeeded Ebert, who died of illness, as the president of Weimar Germany, which started his nearly ten-year presidential career;

One is that Germany was led by Foreign Minister Gustav Stresemann (after the beer hall coup, he was forced to step down as general manager because he was suspected of being related to the coup, and he has been the foreign minister of Weimar Germany since then.) Britain, France, Italy and other countries signed the "Locarno Convention", initially restoring normal relations with neighboring countries.

However, if it is only for the German Navy, the above two things are far less important than the completion of the new light cruiser. On January 1925, 1, the first German new 8-class light cruiser was launched at the Wilhelm Reich Navy Shipyard.This is also the first large and medium-sized warship launched by Germany since the end of World War I eight years ago, which is of great significance!

Since it is of great significance, the choice of the ship's name is naturally cautious. In the end, Admiral Bernke, the commander-in-chief of the navy, made the decision and named the new cruiser the "Emden", which is the same as the previous plane.In the previous plane, at this time, Bainke’s position as the commander of the navy had been replaced by Hans Zenkel, but in this plane, because of his outstanding mediation work at the Washington Conference, Bainke’s reputation in both the political and military circles It has a very high reputation and its status is as stable as Mount Tai.

The name of the ship "Emden" can be said to be of great historical significance to the German Navy.

The second ship of the "Dresden" class of small cruisers launched in 1908 was once named "Emden".During the First World War, this light cruiser with a standard displacement of only more than 3600 tons cruised in the Far East and the Indian Ocean. Relying on the weak firepower of only 10 105mm naval guns, it achieved the remarkable achievement of sinking more than 7 tons of merchant ships and warships of the Allies. record!Although "Emden" eventually ran aground and surrendered under the siege and interception of the superior forces of the Allies, its white hull and legendary experience left the first generation of "Emden" with the reputation of "Oriental Swan".

During World War I, in 1916, Germany named a "Konigsberg" class light cruiser with "Emden", but this second-generation Emden had no legendary experience. It sank in "Operation Rainbow" in 1919 in Scapa Flow.The Emden launched this time is already the third "Emden" in the history of the German Navy.

The outfitting work of the Emden went very smoothly. In July 1925, after completing all the outfitting work and a series of mooring and tilting tests.The Emden finally ushered in its official sea trials.

Although traditionally, the design power of the power system of German ships is relatively conservative, most of the time the actual output power will exceed the design power by a lot.As long as the ship's linear design is not too bad, the trial speed of German warships can generally exceed the design speed, but the ship's designers are still a little apprehensive.

The main reason for the designer's anxiety is that the new light cruiser has applied too many new technologies in reducing sailing resistance and improving propulsion efficiency, although numerous ship model resistance tests and propeller open water tests have been done in the pool.But the experiment is an experiment after all, whether it can achieve the same good effect as the experiment in practical application is still unknown.

In order to test the results of her cheat, Helena was also allowed to go to sea with the ship after begging Admiral Bainke sternly.

On July 7th, the waves rolled in the North Sea outside Wilhelmshaven, and an elegant warship appeared on the skyline, which was the "Emden" under trial voyage.

It has a parabolic forward-sloping bow, a slightly upturned bow, and a small-angle flared freeboard. Three angular dual-mounted turrets are arranged with two front and one rear. The main mast tower just falls on the golden section of the full length of the warship. The front funnel pierces through the bottom of the mast tower, bends backwards and connects with the rear chimney.

Helena is very satisfied with the appearance of "Emden".She has always had an expectation for the future construction of the German army: "Weapons must be cool! Clothes must be handsome! Military songs must be ignited!".

Helena still remembers that when she went to visit Mustache in prison, she also raised this point of view to Mustache. As a result, Mustache was excited as if he had met his lifelong confidant. It's time to chop off the chicken head and burn the yellow characters on the spot.Far away, the Germans don't seem to like this...

Now back on the "Emden", Emden has just completed the cruising test, the machinery is running normally, and the fuel consumption rate is a little lower than expected, and the most exciting speed test is about to begin.

Following the command of the captain, the fuel injectors of the boiler began to spray oil violently into the furnace, and the steam pressure readings rose steadily. faster and faster.

The variable-pitch propeller can be described as a great invention of the Germans. When the propeller rotates forward, the axial pitch at the same radius gradually increases, so that the water flow can be accelerated multiple times when passing through the propeller. The "Bavaria" class battleship used this kind of propeller, which is more efficient than the British.But what is more sad is that the distance between the propeller of the "Bavaria" class and the hull is too close, and the distance between the three propellers is also too close. The mutual interference caused offsets a lot of the improvement brought by the advanced propeller type.This is also an old problem in the design of German warships. In the previous plane, this problem still exists until the Bismarck class.

In terms of the propeller design of "Emden", in addition to correcting the old problem that the German propeller was too close to the hull, Helena also improved the efficiency of the propeller through propeller modification.For the double-variable-pitch closed-knife propeller, not only the pitch at the same radius in the axial direction is gradually increased, but also the pitch at different radii in the radial direction is also gradually increased, and the projection of the blade on the axial side of the axis is made Similar to the shape of Guan Yu's broadsword, the propulsion efficiency has reached the pinnacle of fixed-pitch propellers!

The sea trial area is 100 nautical miles in length. During the nearly three-hour sea trial, the "Emden" with a design power of 72000 horsepower finally ran an astonishing top speed of 80000 knots with an output power of more than 36.6 horsepower. The news came , The bridge suddenly burst into joy.

At this time, no one noticed that looking at the cheering Helena, the old captain in charge of commanding the trial showed an unpredictable and sinister smile on his face.

……
