My German Empire

Although it is a short time to count the nuclear submarine, Jenik is not very disappointed.

After all, the 21st century after decades, nor is it a nuclear submarine in every country. For many countries, it is difficult to manufacture nuclear power submarines in many countries. Therefore, while the nuclear power submarine is vigorously developed, the routine power submarine has not exited the historical stage. Moreover, routine power submarines are more suitable for nuclear submarines in close seas and shallow sea.

Just a routine power submarine has a big defect, that is, if you don't ask for a long time, because the battery capacity installed on the boat is limited, it must be "breathing" in the sea surface, that is, in the ventilation state uses the diesel engine to charge the battery. This is easily discovered by the enemy, and the diesel engine is also easy to be detected by the sonar and other water sound equipment when the battery is charged. As a result, the exposure rate of the submarine has increased, both the concealment of the attack or its own ability to survive.

To solve this problem, all countries have done long-term exploration and efforts, and the development of various AIP power devices has successfully successful and began to enter practical stages.

The so-called AIP is an English abbreviation that "does not rely on air propulsion".

Since the AIP power device does not require oxygen, it can be operated normally, so it can significantly increase the water continued tolerance of the submarine after installing the submarine, so that it is increased in water latent time to 2-3 weeks, which greatly reduces the exposure of the submarine in cruise. rate. In this way, the bottleneck that has always been affected by conventional power submarine operations is finally resolved. Some people have an image of a conventional submarine equipped with an AIP system as a "green nuclear submarine". It means that it has both a large patrolling power of nuclear submarines, and there is no potential danger and high cost of nuclear submarines.

And early Sude and other countries have been involved in the research of AIP dynamics in the early and back of the World War II.

In 1935, the Soviet 18th Central Design Bureau proposed that the AIP system was used on the submarine, and a large number of test data was obtained on the M-92 submarine. However, the technique is not yet mature, and the designer will not rely on air technology as a test problem.

During World War II, Walter, Germany attempted to use compressed hydrogen peroxide in the submarine, as a source of oxygen under water under diesel engine. Those who have learned chemistry know that hydrogen peroxide can be broken down into oxygen and water. When the submarine is running underwater, the thermal energy of the diesel engine is heated to hydrogen peroxide, and then oxygen supply diesel engine is produced. Later, Germany built a small number of AIP submarines.

Cannot like to hydrogen peroxide, because hydrogen peroxide is converted to oxygen, extreme is unstable when the oxygen! In 2000, the Russian military "Kursk" nuclear submarine is due to the disclosure of hydrogen peroxide in the torpedo inside, instant explosion caused a fire, and the high temperature caused a large explosion in seven-fitted torpedo, thus causing history. The largest nuclear submarine sinks disaster, and 118 officers and men on the boat are all killed.

Three of the later generations, the practical AIP scenarios: closed circulation diesel engine, Sterling engine, and fuel cell.

The fuel cell technology is impossible in this era; using liquid oxygen or hydrogen peroxide, it is too dangerous. And until 1993, Germany successfully tried 250 kW closed cycle diesel engine systems on the retired 205 submarine U-1. Jenik does not feel that he can make German technology span half a century; so, in the safest way to use the current technology, it is the use of Stirling Engines.

"General Dunnitz, have you heard of the Stirling engine?" Jeni asked.

Tunz nodded. "What are you talking about British Robert Stelin invented Stelin Engines?"

"Correct."

The 17th and 18th century is a geniuse era. There is a joke, in Paris, 1 copper plate can buy 3 genius.

Watt gave the steam machine with the governor, and human beings entered the steam era, and there was a train, ship. However, this steam is too coal, and it is believed that if the heat of the gas can be used instead of steam, the steam can avoid heat loss caused by condensation.

British scientists Robert Stirling In 1816, an external combustion recirculating thermal air machine was invented in 1816, ie "Stirling Engine". The Stirling engine is output by cooling, compression, heat transfer, and expands by cooled, compressed, heat-insulating, and expands to a cycle of one cycle, and thus is also referred to as a heat gase.

Just lacking good heat resistant materials at the time, and the French engineer Nikola, Leonard, Sadi, Kano, has not yet proposed Kano cycle, people's performance of the heat gases is very limited, known machine The efficiency and power are very low; after the middle of the 19th century, the development of the Stirlin engine will stop with the large number of oil in the inventive internal combustion engine and the large mining of oil.

This Sterling circular hot air engine is not discharged from the original air, except for the original air in the room, so it is also suitable for urban environment and outer space, which guarantees that the routine power submarine is sailing for a long time, no need to The ideal solution for the float.

Dunnitz is some? "But there is a technical reserve in this area. If you want to use this technology on the submarine, you have to start research from the beginning, I am afraid it takes a few years."

"Don't spend a few years, Tunitz will." The Janik's face revealed the smile. "We will get ready-made research results soon."

Dunnitz couldn't help but "Where is it?" I thought it was the secret research department of the temple. I didn't expect the Hall, but I said another country.

"Netherlands. Their Philips started to develop a Stirling engine several years ago, and I have finally developed successfully until I have been successfully developed." A company that made light bulb develops an engine? I don't know what they think, this is cheaper.

Of course, this Sterling engine can only be considered a prototype, and Jenik is not preparing to eat a fat man, and it does not expect the current Sterling engine to provide hundreds of kW power like later generations. It only needs to provide a few Ten kilowatts of power is full. In addition to supplying normal lighting, electronic equipment work and living facilities, the remaining energy can be used to promote submarines, and the submarine is sufficient for half a month in several waterways, it is sufficient.

Dunnitz excited. "That's great, then a batch of 'Tiger Shark' should be able to use this engine." After all, let the submarine have a long time, the most important thing is the most important, reducing the navigation of the ventilation state, Can avoid danger more effectively.

The two will then talk to the tactics of the wolves. "General Dunnitz, what shortcomings do you think 'Wolves Tactics'? Don't have any concerns, just say it."

Dunnitz hesitated, carefully opening the mouth. "His Royal Highness, there are some problems. The biggest problem is the attribution of the command. It is a submarine commander from the sea or the commander ordered to fight on the shore. If the headquarters on the shore will make a combat, it is difficult to do To random strain, it may measure the fighter; it is necessary to give the offline submarine commander. Once the enemy masters the position of the radio transmitted signal, then our submarine is easy to expose. "

Yaki knows that Dunnitz is concerned that the original time and space of the British experts will study the "wolf group" tactics of the German submarine, it believes that if the signal to track the submarine is captured, then the position of the submarine is determined using this signal. The plane can attack fast and effective attacks, so that the "group wolf" cannot attack. British scientists have developed a small high-frequency directional detector that accurately detects the position of the tracking submarine with several instruments measured.

Plus Yingmei sent a large number of destroyers and the aircraft to escort, the arrogant "wolf group", and later became a "flock" that did not have the power.
