Chapter 883 No Red Pigment (Plus 3)

In later generations, the AIP system of submarines is already a technology that various countries are striving to acquire. The cost is low, and to some extent, it can replace nuclear submarines, which is especially popular in poor countries.

Among them, the fuel cell technology is impossible to achieve in this era. Using liquid oxygen or hydrogen peroxide is too dangerous. Therefore, the safest way is to use a Stirling engine.

The Stirling engine was invented by British physicist Robert Stirling in 1816, so it was named "Stirling engine".

The Stirling engine outputs power through a cycle of cooling, compression, heat absorption, and expansion through the working medium (hydrogen or helium) in the cylinder, so it is also called a hot gas engine.

This Stirling cycle hot air engine does not discharge exhaust gas and does not require other air except the original air in the combustion chamber, so it is also suitable for urban environments and outer space. 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, and then gasoline engines and diesel engines came out.

And the application on the submarine is the best means.

Many of the people present were technicians and were no strangers to Stirling engines. Now, when Cyric mentioned the Stirling engine, he immediately understood what Cyric meant.

Using this scheme to realize the concealed navigation of submarines under water is a relatively safe scheme.

"However, we don't have this technology, and if we adopt this solution, it means that we may delay the process." A submarine engineer said: "If we improve the existing submarine in terms of efficiency, add liquid oxygen or Hydrogen peroxide cabin, more efficient."

Cyric shook his head: "But that's very dangerous. Rather than 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 him feel very warm. Now, as the war continues, more and more people in the empire are joining the army to fight in the Quartet. Among these people present, many relatives have joined the army. .

Cyric, the most important thing is the life of the soldiers, such a head of state is worthy of respect.

"Yes, the great head of state, I was wrong." The engineer said immediately. Of course, he also knew how dangerous liquid oxygen and hydrogen peroxide were. If you were not careful, they could easily explode.

"We can study this kind of system in one to two years, without putting forward too high indicators, this Stirling engine, as long as it has a power of tens of kilowatts, is enough, except for the normal lighting on the boat. In addition to the working and living facilities of electronic equipment, the remaining energy can be used to propel the submarine, as long as the submarine maintains a continuous sailing speed of a few knots for half a month, it is enough."

In history, the empire has constantly put forward various abnormal indicators, resulting in the delay in the development of weapons and equipment. Cyric will not make such mistakes.

In later generations, until the 1990s, the Swedish "Gotland" was equipped with two V4-275R Stirling engines with a power of 75 kilowatts each.

Therefore, the index cannot be raised too high now. It is the most important thing to let the submarine have the ability to navigate underwater for a long time. By reducing the navigation in the state of the snorkel, the danger can be avoided more effectively.

The advantages of Stirling engines 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 underwater.

It is just equivalent to adding such a cabin. Once high-speed navigation is required, the original technology is still required.

Cyric put forward lower requirements for various indicators, and it also played a catalytic role in the invention of this machine, and within two years, Germany should not have a large-scale military conflict with the United States. Rick needs a time buffer to solve the Soviet Union's problems first.

At this time, on the other side of the earth, a showdown between submarines and surface ships has just begun.

Over the Pacific Ocean, blue waves are rippling, and the waves are less than one meter high, which is a good time to sail.

A large submarine is sailing on the sea in a floating state. For the submariners, it is already very good to be able to breathe the moist sea breeze.

This submarine is not small, with a total length of more than 100 meters, and an underwater displacement of more than 2,400 tons. It is definitely the largest among submarines.

The front end of the hull is painted with the crooked I-74 hull.

Yes, this is the latest Haida 6b submarine in the service of the island nation's navy!

The submarines of the island nation's navy are named "Yi, Lu, and Bo" in terms of large, medium and small. Similar to the A, B, and C in Chinese, the Yi-type submarines are class 1 submarines with a standard displacement of more than 1,000 tons. A few years later, the island nation's navy has built a big guy with a displacement of 3,000 tons, or even 5,000 tons.

A submariner climbed up from the command tower in the middle. He was not tall and had yellow skin. He said something in a chirping bird song, and then held a sun flag in his hand.

He climbed up and wanted to hang the sun flag on the mast above the conning tower, but just as he was about to pull the rope, suddenly, a sea breeze came, and the sun flag was blown into the sea by the sea breeze!

The following chirping birds continued to come, generally greeting the women in the other party's home, expressing that they wanted to have intimate contact with the other women, and this was a kind of charity, and did not despise the other party's ugly.

"Sanlang, you idiot, why did you throw the flag into the sea?"

"Report, I'm not careful, I'll go get a new one."

"This is the last flag!"

"terribly sorry."

"Sorry bird, bring up your sheets and paint the flag with paint, hurry up!" The voice below was even more dissatisfied.

"Yes."

The stupid sailor Saburo ran to his cabin, and soon, a colorfully painted flag was hung up.

"Idiot, why don't you use red?"

"There is no red pigment, just black ink."

"Baga, bang bang bang!" A few big slaps slapped Saburo's face, and after a few slaps, blood flowed out of his nose.

"It's red now, paint it!"

After a lot of tossing and turning for 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 is going to be a lookout, which is a glorious and sacred task.
