Chapter 881： No red paint (1/2)

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.
