Iron Sonata of World War II

Iron Sonata of World War II Author: Quasar

"Introduction: Tanks running on the field, fighter planes soaring in the blue sky, and ships sailing on the ocean, how are their steel bodies built?

This is an overhead World War II time travel novel with weapon design as the core. "

Chapter 1 German class

On May 1931, 5, the economic crisis sweeping the entire capitalist world has begun for more than a year. Although the westerly wind from the Atlantic Ocean has already brought back a warm atmosphere to the European continent, the economy still has not seen any recovery. The ever-increasing queues of unemployed waiting outside relief food distribution points on the streets of Germany make this spring look extremely bleak.

But Deutsche Werft in Kiel is an exception to the gloom that hangs over the country.On this day, the east was just getting brighter, and the shipyard began to get busy. The workers were making the final arrangements for a tall viewing platform.When the sky gradually brightened, the road leading to the shipyard became lively. Cars drove over groups of concierges in costumes. As the concierges sat down one after another, the originally quite spacious viewing platform was also full. full.It wasn't just the viewing platform that was overcrowded, the open space around the berth was also full of shipyard employees, and even a large number of onlookers gathered on the pier outside the shipyard.All eyes were focused on the berth in front of the viewing platform, where a huge off-white battleship decorated with colorful ribbons was gradually becoming clearer in the morning light.

It has a body shape of about 200 meters. Although no turret and superstructure have been installed yet, the forward-sloping parabolic bow and the slightly flared freeboard still appear calm and elegant without losing agility and elegance. "Oh, look, she's such a beauty!" Someone in the crowd praised the battleship, which immediately elicited voices of praise.

Suddenly, people turned their attention to the entrance of the viewing platform, where a burly old man walked up to the viewing platform accompanied by Admiral Raeder. He had a square face with Chinese characters and wore a hat from the Second Empire period. The Prussian military helmet with a pointed top, the two beards above the lips are raised towards the cheeks with personality, although the temples have turned gray, but the gaze is still as sharp as a falcon, and the crowd that was still noisy just now suddenly fell silent.

This old man is the President of the Weimar Republic: Paul von Hindenburg, the veteran who commanded the war against Tsarist Russia with Ludendorff on the Eastern Front of World War I and won the victory at Tannenberg. In his twilight years, Hindenburg still dragged his unhealthy body to Kiel to participate in the launching ceremony of the new ship, which is enough to show that the entire German team attaches great importance to this new ship. After all, Germany in the economic crisis needs one too much. It's a happy event to boost people's hearts, and the German navy under the yoke of the "Treaty of Versailles" really needs a new ship to boost morale.

President Hindenburg boarded the rostrum and delivered a speech on the launch of the new ship. In the speech, President Hindenburg praised the efforts of the naval officers and soldiers, shipyard workers and ship designers. Finally, the president gave the warship the official ship title Name: "Deutschland", this ship name is not only an affirmation of the German shipyard, but also the expectation of the whole country for the first [-]-ton warship built by Germany after the end of World War I.

After the president’s speech, a bottle of champagne was smashed on the bow, and the silk cloth covering the ship’s nameplate was slowly lifted, revealing the name of the ship “Deutschland”. The shipyard workers released the anti-skid device, and the huge hull of the “Deutschland” Then he slid into the sea along the slide rails, causing a huge splash. The whole launching process went very smoothly, and the crowd on the viewing platform, around the berth, and on the pier cheered loudly.

At this exciting moment, there was a young girl on the viewing platform who seemed a bit out of place with the surrounding environment. She did not cheer with the crowd, but looked at the scene in front of her with a smile, appearing calm and elegant.But if we walk into the inner world of the girl, we will hear the girl asking with some anxiety in her heart: "System, we have changed the power system of the German class from a diesel butterfly to a circular furnace supercharged boiler with an impulse steam turbine." , shouldn't something be wrong?"

Chapter 2 The beginning of time travel

Let us go back to June 1914, 6. General Hans von Seeckt, then chief of staff of the 27rd Army in Berlin, was pacing back and forth in the corridor of his home, looking at the bedroom door from time to time. In the direction, there are cries of pain from pregnant women from time to time.Suddenly, the screaming of pain subsided, and there was a loud cry of a baby in the bedroom, followed by the long gasps of the medical staff.Then, the door of the bedroom opened, and General Sektor, who had been anxiously waiting outside the door, hurried up to greet him, "Congratulations, General, you are a beautiful daughter." The doctor who just took off his mask wiped the sweat from his head. explain.

……

Three days have passed, and the protagonist named Helena Seckert by the Seekert couple has just recovered from the shock. Just three days ago, Li Bo was a young Chinese man working on a small agricultural machine. The factory acts as its own technicians.Outside of work, Li Bo's biggest hobby is to log into his online account named "Pingdu Zhenlu", and point out various weapons during World War II in various military weapon forums.Because Li Bo always sprayed German weapons to nothing, and at the same time devalued Soviet equipment to nothing, and from time to time did not forget to step on British and American goods, Li Bo soon became the public enemy of WWII weapon lovers .Don’t look at the World War II weapons fans who are fans of German equipment, Soviet equipment, and British and American equipment. They usually get angry when they meet, but in front of Li Bo who is spreading hatred everywhere, fans of weapons from various countries have a bit of the same hatred smell.

However, every time Li Bo can always take out the materials without any haste, spray the materials, and go offline immediately after uploading the materials, without taking a cloud, leaving all the fans in the forum with a piece of shit The flying dog jumped, while Li Bo watched the flames of war he ignited happily.

Probably the resentment of the huge number of World War II weapon lovers towards Li Bo shocked the heavens. In a dark night where you can't see your fingers, Li Bo was unfortunately bound by this system called "Iron Heart" in his sleep, thus becoming a A member of the crossing army.

The "Iron Hearts" system told Li Bo that because the resentment of countless military fans disrupted the operation of time and space, Li Bo must be dispatched to a parallel time and space before World War II, and let this time and space emerge under the influence of Li Bo. As compensation for the military fans, only the weapons and equipment that military fans lick their fingers are eligible to return to the 21st century.Faced with this hell-level difficulty task, Li Bo immediately showed his essence of being a cannonball. After all, Li Bo was just a technician in a small agricultural machinery factory before. The dazzling weapons and equipment are tantamount to idiotic dreams. Fortunately, the system said that it can provide data assistance for Li Bo, so Li Bo reluctantly accepted his tragic fate.

Since the Soviet Union and Germany have the largest number of fans of weapons and the greatest resentment towards Li Bo, after Li Bo reluctantly accepted the time-traveling task, the system gave Li Bo two choices, one is to travel to the Soviet Union before World War II, and the other is to travel to the Soviet Union before World War II. to Germany before World War II.

Li Bo considered it again and again, and finally chose to travel to Germany.The reason is, firstly, that the Soviet Union before World War II was undergoing major purges, and there was a risk of being sent to Siberia by comrades of steel to accompany polar bears if you went to the Soviet Union; It is more conducive to the completion of the task.

"Have you chosen?" The mechanical voice of the system carried a hint of banter that Li Bo could not detect, "I have chosen." After adjusting his mentality, Li Bo firmly replied that adaptability is one of his few advantages.

"As you wish, my host." The system said, a white light flashed, and the scene we started with appeared.

……

"You mean that if I choose to go to the Soviet Union, I will be given the status of a boy?" the infant Helena Seckert asked with grief and anger in her head. "Yes." The system's voice didn't fluctuate, but Li Bo knew that if the system had an entity, his face would be smiling like a chrysanthemum at this moment.

"Let me go, let me go to the Soviet Union, I'm going to Siberia to be with polar bears!" Li Bo, oh no, Helena should be waving her little hand now, but the system just projected an expression of rolling eyes on the light curtain package, and exit the interface.

"Oh, my little Helena, do you miss Daddy?" Sektor's wife, Dorothy, who is also the mother of this body, saw Li Bo waving his arms and gently hugging the three-day-old baby girl, Rocking in his arms, two days ago, Ferdinand and his wife, the crown prince of the Austro-Hungarian Empire, were assassinated by the Serbian nationalist Princip. Sektor had to bid farewell to his wife who had just given birth and rush back to the army. The bearded lips kissed her daughter, making little Helena scream.

It may be that the various blows of the past few days made Helena physically and mentally exhausted. In the arms of her mother, Helena's eyelids gradually sank. The idea is: From now on, I will be Helena, the only daughter of General Sektor, who never existed in history.

Chapter 3 Emden

The gears of the world continue to operate normally. Like the previous plane, the Sarajevo incident still triggered the First World War. After four years of tragic fighting, Germany was defeated and signed a harsh treaty on June 1919, 6. "Treaty of Versailles".Obviously, Helena, a little butterfly, does not yet have the ability to shake the world line.

Hans von Seeckt, Helena's father, remained Chief of the Postwar General Staff of the German Army in July 1919 and became Commander-in-Chief of the Wehrmacht a year later.

Although becoming the daughter of the commander-in-chief of the National Defense Forces, it does not seem to be of much help to our little Helena's crossing mission. There are two main reasons for this:

One is that the Treaty of Versailles imposed strict restrictions on Germany's armaments. The number of troops could not exceed 15000, tanks and fighter planes could not be owned, and heavy machine guns and large-caliber artillery could not be developed.The situation of the navy can also be described as tragic. The number cannot exceed 36, and only [-] old warships are allowed to remain. Submarines and aircraft carriers are even banned.

The second is that Helena is too young. The words of a little girl of a few years old really don't carry much weight. Even if she is the commander-in-chief's daughter, others probably won't take it too seriously.

However, this "others" does not seem to include General Sektor himself. Helena remembered that day when she was six years old, she brazenly tilted her head to show off to her father in this life, and at the same time expressed her own ideas about how to keep under the restrictions of the treaty. When the suggestion of the army's combat effectiveness was uttered, Sekte, who was sitting on the chair, stood up abruptly, with such force that the round-rimmed glasses that had been wearing on his left eye fell off.

In his previous life, General Seekert was known as the founder of the "One Hundred Thousand Army", and he deserved his name. Under the strict restrictions of the "Treaty of Versailles", he preserved the essence and combat effectiveness of the German Army to the greatest extent.In fact, speaking of it, Helena felt a little guilty, because most of the suggestions she made were the practices of General Sektor in the previous plane, which was summed up bit by bit in practice, and I don't know if this is considered plagiarism. own father's intellectual property.

After this incident, when Helena showed her interest in weapons, Dad Sektor let it go all the way. With Dad's support, Helena was soon filled with line drawings and models of various weapons. study.

The time entered 1921, and the German military industry, which had been silent for several years, was finally ready to make big news. The navy was preparing to submit an application to the Allied Supervision Committee (ACC) to build a cruiser with a displacement of 6000 tons (later Emden No. 20 generation), to replace the old cruiser that has been in service for [-] years.

But in the last plane, the Germans made a big oolong about this matter!

According to the regulations of the Allied Supervision Committee, the standard displacement of the new ship shall not exceed 6000 tons.The unit used in this provision is the long ton, and the standard adopted is the British Standard.

As a result, the Germans understood the unit as a metric ton (1 long ton is approximately equal to 1.016 metric tons), and the standard as the German standard (calculating the displacement of the same ship, the result calculated by the German standard will be heavier than that by the British standard).The two misunderstandings superimposed each other, resulting in the planned displacement of the new German ship calculated according to ACC standards to only 5280 tons, and the already tight displacement index was wasted by another 12%.

So in this matter, the little butterfly who knew this history, ah no, it was Little Helena who decided to start flapping her wings.Needless to say, as a veteran Junker class, the economic conditions of the Seckert family are quite good, so several designers who had participated in the design of warships during the Second Empire were invited into the Seckert family.When several designers were quite dissatisfied with the fact that professionals like themselves were invited just to satisfy the curiosity of a seven-year-old girl, but in the context of the sharp shrinkage of the German military and civilian shipbuilding industry, even the vitality of the Facing the predicament, the designers still chose to bow their heads, but their little awkwardness was soon replaced by incomparable shock.

"This is a 7100-ton cruiser designed by one of your foreign counterparts. Do you think it has any reference value?" Helena pointed to the blueprint in front of her eyes.The drawings on the table were actually drawn based on the Aoba-level design materials provided by the system.

The Furutaka/Aoba class (the main difference between the Furutaka class and the Aoba class is that the Furutaka class uses six single-mounted turrets when it is built, and the Aoba class uses three double-mounted turrets) is a Japanese military that started construction in 1922. The heavy cruiser was designed by the famous ship designer Joe Hiraga. Since the armor belt is incorporated into the load-bearing system, the main armor is inclined 9 degrees to improve the protection ability and other novel designs. Although the subsystem performance of Furutaka/Aoba is not high (For example, the boiler steam temperature is only 156 degrees Celsius), but the overall performance was the leader among cruisers of the same tonnage at that time.

"The designer of this warship is a genius! If the power system does not hold back, the combat effectiveness of this cruiser will surpass all 7000-ton warships!" A designer praised, and several others also nodded.

"Everyone must have had a rough time after the war, right? But now there is a once-in-a-lifetime opportunity in front of you, I wonder if you are willing to give it a try?" A fox-like smile appeared on Helena's immature face, which made people feel a little worried. An inexplicable sense of incongruity.

……

"This is an extremely serious mistake! If this plan is submitted to the ACC, the German Navy will become the laughing stock of the world!" Vice Admiral Paul Bainke, the commander of the Navy of the Weimar Republic, slammed his desk hard. Darang made all the decorations on the table jump up as if shocked. "Fortunately, it was discovered in time. This time, the navy owes the army a great favor." In front of Behnke was a letter from General Seckert, the commander-in-chief of the National Defense Forces.

This was of course Helena's masterpiece. After she told her father that the navy might have misunderstood the treaty's standards, Seckert thought it was incredible, but he still wrote this letter.Although the army and navy have always been enemies when fighting for the budget, now the German army and navy can be regarded as "the same people who have fallen in the end of the world", and Sektor is not willing to see the navy suffer.Besides, the navy owes the army favors this time, and favors always have to be repaid.

Along with Seekert's letter, there was also a joint manuscript by a group of warship designers during the Second German Empire. The manuscript contained the design proposals for two new warships. The standard displacement was just controlled on the ACC standard line. 6000 tons.

first plan

The main gun adopts four double-mounted 155mm main guns, and the central axis is arranged head-to-tail

The power is ten heavy oil boilers, two steam turbines, 50000 horsepower, and the estimated speed is not less than 31 knots.

The armor area covers the entire power cabin and ammunition depot, the vertical armor is 70mm inclined at 12 degrees, and the horizontal armor is 35mm

The turret and conning tower armor is only 25mm, which can only protect against close-range fragments

The second set of plans

The main guns are reduced to three double-mounted 155mm main guns, with two front and one rear on the central axis, and two front seats

The power has been increased to 12 heavy oil boilers, and there are still two steam turbines with 60000 horsepower. The estimated speed is not less than 33 knots

The armor area still covers the entire power cabin and ammunition depot, the vertical armor is strengthened to 90mm and the slope is 12 degrees, and the horizontal armor is 40mm

The front of the turret is 105mm inclined at 45 degrees, the side and rear are 60mm, and the top is 45mm

The side of the conning tower is 105mm inclined at 12 degrees, and the top is 45mm

At the end of the manuscript, the designer of the letter also mentioned that the four-seat double-mounted plan may be rejected by ACC, so three double-mounted plans are provided as an option.This is of course Helena's idea. In history, after Germany found out that it had made a mistake in the ACC standard, it submitted a plan with four double-mounted 150mm guns, but it was rejected by ACC. The Germans had to pick up the original The original 5280 tons of 8 single-mounted turrets were slightly repaired. In the end, the standard displacement of the Emden fell to 5608 tons.

Someone asked why the caliber of the artillery has changed to 155mm. The commonly used caliber in Germany is obviously 150mm. The next chapter will explain this.

Chapter 4 The treaty is coming

Lieutenant General Behnke stared at the two plans in front of him. The anger and fear caused by Germany's misunderstanding of the tonnage standards of the Allied Supervisory Committee were swept away and replaced by extreme surprise.

The first of these two plans is obviously just a smoke bomb, the purpose is to exchange for the second plan with weaker firepower to make it easier to get the "birth certificate" of ACC.

But even the second option was exciting enough that Behnke even thought it was better than the first!

Although the firepower of the eight 155mm main guns in the first plan is very powerful, the four double-mounted 6-inch main guns are still too crowded for a warship with a standard displacement of only about 6000 tons. The direct consequence is that its turrets and The conning tower is only protected by a mere 25mm steel plate. This thickness can only resist the fragments of shells that are not directly hit. deadly threat.With a 70mm broadside inclined at 12 degrees and a horizontal 35mm hull protection, it can be regarded as quite excellent among warships of the same tonnage in this era, but it is still powerless to defend against the 6-inch artillery strikes of cruisers.And in order to prevent the armored area from being stretched too long, the power of the first plan was also weakened.

In contrast, the second plan is much more balanced. Although there is one less dual-mounted main turret, all the main turrets are covered with thick armor, 90mm vertical armor inclined at 12 degrees and 40mm horizontal armor It also allows the core cabin of the battleship to have enough confidence to face the enemy's 6-inch naval guns (the power of the 20-inch naval guns in the 6s is not as perverted as it was in the 40s!).In addition, the increase in power makes the speed of this scheme more than 2 knots faster than the first one, and the speed of more than 33 knots is also an excellent level among cruisers.

However, there is one thing that still confuses Lieutenant General Behnke, that is, why the caliber of the main guns of the two schemes is 155mm, instead of the 150mm (actually 149.1mm) used by Germany before?Although in Behnke's heart, he also hopes that the main gun of the new ship can be stronger. In the past, the High Seas Fleet had a big business, and the light cruiser was just doing miscellaneous work. Even using a 105mm toothpick gun is not a big deal. A 6000-ton light cruiser is just for show, and it would be good to increase the caliber of the main gun by one millimeter!

You must know that although the major naval powers all have their own 6-inch naval guns, the specific calibers are still a little different.The more mainstream ones include the 150mm guns commonly used by the Germans (actually 149.1mm), the 152.4mm guns commonly used in Britain and other countries, and the 155mm guns developed by some navies with metric calibers.

However, if the new ship rashly expands on the basis of the traditional German caliber, won't it lead to ACC's veto?Lieutenant General Behnke decided to ask the designer, but he didn't know if he didn't ask. He was shocked when he asked. special only daughter Helena.Bainke tried his best to piece together the image of Helena relying on the memories of the few encounters in his mind, but he could only find a vague shadow, which seemed to be a cute little girl. The Te family was not really close.

With question marks in his stomach, Lieutenant General Bainke finally decided to visit Sektor's house to find out what happened.

……

In the living room of General Seekert’s house, on behalf of the Navy, Bainke first expressed his gratitude to Seekert for ignoring the long-term estrangement between the Army and the Navy, and sent a letter reminding the Navy that the ACC standard may be wrong (this time it is absolutely sincere). Just about to inquire about Helena's affairs, he suddenly heard a clear and clear child's voice from behind the door, "Dad, why is Uncle Paul here?" Then a small figure rushed into the living room.

"Crazy girl, say hello to uncle!" Seekert gave his daughter a hug.

"Hello, Uncle Paul! Did Uncle Paul bring me a gift? Last time, Uncle Paul agreed to give me a model of a battleship." After living in the body of a little girl for seven years, Helena has already mastered the trick of being coquettish and cute. Facing the lily-like pure smile of the little blond girl in front of her eyes, the poor Bainke tried desperately to recall if he had promised Helena anything during the few banquets where he and Helena had intersected. The little girl's expectant eyes made Bainke feel deeply guilty, and he almost wondered if he had cheated a child's feelings.

"Cough cough." Lieutenant General Paul Bainke took a sip of tea in embarrassment, but he almost choked because he drank it too fast. "Uncle forgot to bring it this time, and I will definitely give it to you next time."

After the blackmail was successful, Helena naturally reciprocated and answered Bainke's questions.

"Uncle must know that the United Kingdom, the United States, Japan, France and Italy are preparing to hold an international conference to discuss the control of the naval arms race?" Helena asked.

After the end of the war, Germany, once the world's second largest naval power, was disarmed, but the worldwide naval arms race did not die down, but instead re-entered a fever.The world's major naval powers, especially the United States, Britain, and Japan have successively formulated huge shipbuilding plans.However, European countries have been exhausted by the world war and are unable to sustain a long-term arms race; if Japan's shipbuilding plan is fully implemented, it will be enough to bankrupt its own finances. The situation in the United States is better, but it will overwhelm the United Kingdom Nor is it easy.Therefore, it is a matter of course to limit the intensity of the arms race through treaties and let countries take a breather.At this time, the Washington Conference (the last plane will open on November 1921, 11) is brewing, but various preliminary discussions and preparations have already been carried out in full swing.

Bainke nodded. Apparently, Bainke was also aware of all kinds of open and secret struggles in various countries around the upcoming Naval Arms Control Conference.

"This is our chance. May I ask which country in the ACC is the most active in containing us?" A seven-year-old girl, but a veteran politician who is well versed in current affairs.

"Of course it's France." Behnke told the truth, out of the consideration that the United Kingdom does not want France to become the only military power on the European continent, it has actually never advocated excessive restrictions on Germany. It seems that even if Germany doubles its navy, which only has a few dilapidated former dreadnoughts, it will only be France who has a headache.

"That's right!" Helena said, "But this time, if we want to expand the caliber of the naval gun to 155mm, the French will definitely support it."

"What? The French wish that we don't even have a sampan, and will support us to adopt a larger caliber 155mm gun?" Behnke couldn't help but widen his eyes.

"Helena is right!" Seekert, who had been sitting by the side without speaking, had obviously guessed Helena's charade. "The reason why France will support us to expand the caliber is because of the dispute over the caliber standard at the arms limitation conference!"

Of course, Bainke is not a fool to become the commander-in-chief of the navy, and he immediately understood the key point, "Okay! This is probably possible!" Bainke stood up with a slap on his thigh, took Helena's hand and said, "The navy will Thank you, sweet little angel."

It turns out that since the Naval Arms Control Conference is going to discuss the restrictions on the performance of warships of various countries, it must involve the caliber of the main guns. However, the calibers of naval guns adopted by various countries are not the same, and which standard to adopt has become a hot spot in the conference.

On the one hand, if the caliber of other countries becomes the limiting standard at the meeting, if the caliber of the main gun of the warship of the country is larger than this caliber, it will face the embarrassing situation of either retiring or changing the gun; if it is smaller than this caliber, it will take time and effort. To expand the bore, one has to accept that the caliber of one's main gun is smaller than that of warships of the same level in other countries.

On the other hand, the caliber standard is not only an economic issue and a performance issue, but also a political issue. Whoever adopts the standard demonstrates the influence and voice of a big country in the world!

As the country of origin of the metric system of measurement and the standard-bearer of the promotion of the metric system of measurement, France is particularly enthusiastic in competing for the caliber standard of naval guns.Of course, in history, the "Washington Treaty" signed in 1922 finally adopted the British caliber. The main guns of battleships did not exceed 16 inches (406mm), and the main guns of cruisers did not exceed 8 inches (203.2mm).However, in the "London Naval Treaty" signed in 1930, France finally found a place on light cruisers, destroyers and submarines: the caliber of the main gun of the light cruiser does not exceed 155mm, and the caliber of the main gun of the submarine and destroyer does not exceed 130mm (interesting Unfortunately, the proud French finally won the naval gun caliber standard in the "London Naval Treaty", but France itself did not participate in the "London Naval Treaty". Britain said: Are you kidding me?).

"Although the arms control meeting is still in the making, France is obviously at a disadvantage in formulating naval gun caliber standards. If Germany publicly expresses that it is on par with France in terms of naval gun caliber standards, France will not accept it even out of political considerations." It is unlikely to object! It may even be advertised as another victory for the French standard!" Behnke said excitedly.You must know that the barrel cross-sectional area of ​​the 155mm gun is about 149.1% larger than that of the 8mm. If you make good use of it, the power of the main gun can be greatly improved (Japan in the previous plane, in order to maximize the cruiser’s main gun under the treaty restrictions) The power of the gun has been expended to expand the main guns of Furutaka, Aoba, and Myo, from 200mm to 203.2mm).

Talk about a French destroyer equipped with 138mm guns. The French call this type of destroyer not a destroyer, but an "anti-destroyer lightning strike ship". Other countries generally call it a "super destroyer", and its positioning is a destroyer killer.In this line of French super destroyers, except for the Jackal class, which has a 130mm gun, the Cheetah/Eagle/Vauqueland class, Utopia class, and Mogador class behind it all have 138mm guns.However, the London Treaty did not recognize the super destroyer as a ship type, and then France and Italy quit.

Chapter 5 Oxygen Torpedoes

Bainke felt that this visit could be called a fruitful one, and now his mind was full of thoughts on how to implement this matter, and he seemed a little absent-minded in the subsequent chat.

But Helena obviously wasn't going to let him go, so a bigger pie fell on Bainke's head.

"Uncle Paul, we in Germany have tested torpedoes powered by compressed pure oxygen, right?" Helena asked.

"Yes, we have done related experiments, but all attempts have failed. The deflagration problem cannot be solved. The researchers tend to think that it is technically impossible to use pure oxygen torpedoes." Bainke didn't know why Helen Na would suddenly change the subject to torpedoes, but answered Helena's question with a smile.

When it comes to torpedoes, according to their power types, there are mainly thermal power, compressed air power and electric power.Compressed air power is the simplest. It relies on compressed air to drive the propeller forward. Its masterpiece is the famous "white-headed torpedo". However, the energy storage density of compressed air is too low and the range is too short, so it has not been developed for a long time.In this era, electric torpedoes have no mature products due to the insufficient energy storage density of batteries.So the mainstream torpedo power type in this era is thermal power.

Thermal power uses a heat engine to drive the propeller, but the heat engine needs fuel and oxidant to do work. The underwater torpedo cannot directly obtain oxidant from the atmosphere like a ship, but can only carry its own oxidizer.The oxidant of early torpedoes is compressed air, but only 21% of the oxygen content in the air, the rest is 78% of nitrogen and 1% of other gases.This greatly limits the range of the torpedo, and nitrogen is not only incombustible, but also not easily soluble in water, which causes the exhaust gas after burning to form a very obvious wake behind the torpedo, which is equivalent to telling the enemy ship: "Torpedo Come rushing over, quickly hide!"

Military scientific researchers soon thought of using pure oxygen instead of air as the oxidant, so that the same pressure tank can carry nearly five times the oxidant, and the range of torpedoes can be greatly extended.What's even better is that the combustion products are basically water and carbon dioxide soluble in water, which greatly reduces the torpedo wake and improves concealment.As a result, countries have set off a wave of research and development of oxygen torpedoes.

However, the ideal is full and the reality is very skinny. Ignition in a high concentration of oxygen has become an insurmountable difficulty. The endless deflagration and even explosion accidents have made the navies of various countries lose their patience, and the oxygen torpedo has been shelved.

It may be a mistake. In 1926, Japan learned from the gossip that Britain had developed an oxygen torpedo (in fact, it was not true), so Japan, which was keen on lightning strikes, restarted the development of oxygen torpedoes, but there were still accidents.By chance, the torpedo R&D team led by Kakoji Kishimoto, who was the second section chief of the first department of the Fleet Administration Headquarters at the time, discovered that if the fuel was allowed to burn stably in the air first, and then inject pure oxygen into the combustion chamber, the torpedo would not be damaged. Will cause an explosion.

Sometimes the technological breakthrough is to climb Mount Everest, but sometimes it is really to pierce a piece of window paper. Japan quickly designed a torpedo that mainly uses pure oxygen as the oxidant.The specific method is to use two air tanks, one large and one small, the small air tank contains ordinary compressed air, and the large air tank contains compressed pure oxygen.After the torpedo is launched, the air in the small gas tank is first introduced into the combustion chamber to ignite. After the combustion is stable, pure oxygen is introduced from the large tank to the combustion chamber, so that deflagration will not occur.

This is the origin of the famous Type 610 oxygen torpedo in the future. The Type 490 torpedo with a caliber of 48mm has amazing power and range. By 20 knots, the range can reach 35 kilometers!
