In later generations, the submarine AIP system is already a technology that all countries are striving to obtain. The cost is low, and it can replace nuclear submarines to some extent. It is especially popular in poor countries.
The fuel cell technology is impossible to achieve in this era. The use of liquid oxygen or hydrogen peroxide is too dangerous. Therefore, the safest way is to use a Stirling engine.
The Stirling engine was invented in 1816 by the British physicist Robert Stirling, so it was named "Sterling Engine".
The Stirling engine uses the working medium (hydrogen or helium) in the cylinder to output power through a cycle of cooling, compression, heat absorption, and expansion, so it is also called a heat engine.
This Stirling cycle hot air engine does not exhaust exhaust gas. It does not require other air except the original air in the combustion chamber. Therefore, it is also suitable for urban environments and outer spaces. It is to ensure that conventional powered submarines can sail underwater for a long time without The ideal solution for floating.
However, this kind of engine did not enter the real effective application process. The Stirling engine was proposed to change the low efficiency of the original steam engine. After that, gasoline and diesel engines came out.
However, it is the best method to use on submarines.
Many people present were technicians and were no strangers to the Stirling engine. Now, hearing Cyric mentioning the Stirling engine, he immediately understood what Cyric meant.
Using this scheme to realize the concealed navigation of underwater submarines is a relatively safe scheme.
"However, we do not have this kind of technology. If we adopt this scheme, it means that we may delay the process." A submarine engineer said: "In terms of efficiency, we improve the existing submarine, increase liquid oxygen or The hydrogen peroxide compartment is more effective."
Cyric shook his head: "But it's dangerous. Compared to serving quickly, I value the safety of our soldiers more. For the Empire, every soldier's life is precious."
This sentence made the people around me feel very warm. Now, with the continuous progress of the war, more and more people in the empire join the army and go to fight in all directions. Among these people present, many relatives have joined the army. .
Cyric, the most important thing is the life of the soldier. Such a head of state is worthy of respect.
"Yes, great Führer, I was wrong." The engineer said immediately. Of course he also knew how dangerous liquid oxygen and hydrogen peroxide were. If you didn't pay attention, it would easily explode.
"We can spend one to two years to study this kind of system. There is no need to propose too high indicators. This kind of Stirling engine, as long as it has a power of tens of kilowatts, is sufficient, except for the supply of normal lighting on the boat. , In addition to the work and living facilities of electronic equipment, the remaining energy can be used to propel the submarine. The submarine only needs to keep sailing continuously for half a month at a underwater speed of a few knots."
In history, the empire has continuously put forward various perverted indicators, leading to delays in the development of weapons and equipment. Cyric will not make such mistakes.
In later generations, it was not until the 1990s that Sweden’s Gotland was equipped with two V4-275R Stirling engines each with a power of 75 kilowatts.
Therefore, the index cannot be raised too high now. It is the most important that the submarine has the ability to navigate underwater for a long time. Reducing the navigation of the snorkel state can more effectively avoid danger.
The advantages of the Stirling engine are high efficiency, low noise, low pollution, and low operating costs. However, the power of the Stirling engine is small, so it is generally used directly to drive the submarine to sail slowly under the water.
It is just equivalent to adding such a cabin. Once high-speed navigation is required, the original technology is still needed.
Cyrek put forward lower requirements for various indicators, and it also played a catalytic role in the invention of this machine. In two years, Germany should not have a large-scale military conflict with the United States. Rick needs time buffer to solve the Soviet problem first.
At this time, on the other side of the earth, a duel between submarine and surface ship had just begun.
Over the Pacific Ocean, blue waves are rippling, and the waves are less than one meter high. It is a good time for sailing.
A large submarine is sailing on the sea in a buoyant state. For the submarine soldiers, it is already very good to be able to breathe the wet sea breeze.
This submarine is not small in size, with a total length of more than 100 meters, and an underwater displacement of more than 2,400 tons. It is definitely a large submarine.
The front end of the hull is painted with crooked Yi-74 ship.
Yes, this is the latest Haida 6b submarine in service by the island navy!
The island navy submarines are named "I, Lv, and Bo" in large, medium and small categories, similar to the Chinese A, B, and C. The Iraqi submarine is a Class 1 submarine with a standard displacement of more than 1,000 tons. And a few years later, the island navy built a big guy with a displacement of 3,000 tons, or even 5,000 tons.
A submarine soldier climbed up from the control tower in the middle. He was not tall and had yellow skin. He spoke in a whispering bird language, and then he carried a sun flag in his hand.
He climbed up and wanted to hang the sun flag on the mast above the control tower, but just as he was about to take the rope, suddenly, a sea breeze blew, and the sun flag was blown into the sea by the sea breeze!
The whispering babble continued from below, roughly greeting the women in the other's family, expressing that they want to have close contact with the other's women, and this is still a kind of charity, not to dislike the other's ugliness.
"Saburo, you idiot, why did you throw the flag into the sea?"
"Report, I was not careful, I will get a new one."
"This is the last banner!"
"very sorry."
"Sorry bird~www.novelhall.com~ Bring up your sheets and paint the national flag with paint. Hurry up!" The voice below became even more dissatisfied.
"Yes."
The idiot Sailor Saburo ran to his cabin, and soon a colorful flag was hung out.
"Idiot, why not use red?"
"There is no red paint, only black ink."
"Baga, slap, slap!" A few big slaps on Saburo's face, a few times, blood came out of the nose.
"It's red now, paint it!"
After a lot of tossing, it took a full half an hour. Finally, this flag with a bed sheet, mixed with black paint and red blood stains, was hung up and fluttered in the wind.
Blocking his nose, Saburo continued to stand on it. Now, he wants to be a watchman, which is a glorious and sacred task.
