In the past, the power of Sterling engines was relatively small, among which the power of the dedicated Sterling engine on the AIP submarine was usually only 50~75 kilowatts, and the largest one was only 125 kilowatts.

However, the high-power Stirling engine developed by the third brother and the others this time will have a prototype power of 280 kilowatts, and it is expected to increase the power to the megawatt level in the future.

One megawatt is 1,000 kilowatts. If there is a Stirling engine of this level, only 2 to 3 units can be connected in parallel to provide thousands of kilowatts of power. Then the submarine can completely abandon the diesel engine and directly use the combination of Stirling engine + battery.

This means that the submarine can save hundreds of tons of weight and free up more than ten meters of cabin to install larger liquid hydrogen and liquid oxygen tanks.

In this way, even if you use the Stirling engine, conventional submarines can have a maximum underwater speed of 15 to 20 knots. When the snorkel is sailing, the Stirling engine can directly absorb oxygen from the air and work, and can also charge the battery, thereby obtaining stronger underwater endurance.

It is also worth noting that the Stirling engine is an external combustion engine, so it is enough to heat one end of the cylinder, but the heating method does not necessarily have to be achieved by burning liquid hydrogen and liquid oxygen.

This provides more options for Stirling engines. For example, installing a small nuclear reactor on a submarine and driving the Stirling engine to expel heat from a small nuclear reactor. Compared with the traditional nuclear reactor + steam turbine system, the combination of nuclear reactor + Stirling engine has the advantages of fast start-up, high thermal efficiency, low noise, no corrosion and water leakage, and the entire system is simple and reliable.

Moreover, this kind of submarine only needs a small nuclear reactor with very small power to operate continuously, and its tactical performance is higher than that of ordinary AIP submarines, which is a promising development direction in the future.

In fact, in addition to submarines, the Sterling engine also has an important purpose - space exploration.

Because space is close to vacuum, various machinery powered by fuel and oxygen on the earth in the past could not be used normally. Modern nuclear power devices also need to use steam turbines to transmit energy, that is, "nuclear energy → steam → steam turbine → generator → electrical energy".

In the middle, three conversions of steam thermal energy, mechanical kinetic energy and electrical energy have been experienced, so the efficiency is relatively low.

Moreover, if a nuclear reactor is connected to a steam turbine, it will not only be inefficient, but also require a lot of water. Because the nuclear reactor has two circuits, the first circuit requires heavy water, and the second circuit uses ordinary distilled water, so it is large in size, heavy in weight, and has low reliability.

If a Stirling engine is used, the Stirling engine can be directly heated with a nuclear reactor and then provided kinetic energy, so it is more efficient and smaller, making it very suitable for the energy system of the space station in the future.

Of course, all of this is still conception and possibility. If you really realize it, you don’t know how many setbacks you will have to go through.

But it has to be admitted that the third brother and the others have a cross-generational significance for the breakthrough in Sterling's engine power this time.

But the third brother undoubtedly has to be an unsung hero this time, because Ye Yuze is destined not to give it to others with such skills.

At least the third brother had already taken confidentiality measures before the research and development, and hired different personnel at each stage. When the prototype was finally assembled, he was the only one left.

Ye Yuze called Lao Liu and briefly explained the situation. His words were very obscure, and even if others heard it, they would be unaware of it.

Lao Liu naturally understood and was very excited. He asked Ye Yuze to wait for a while, and he needed to report to the above.

An hour later, Lao Liu called and asked him to fly straight to Dalian where someone would wait for him.

Ye Yuze did not hesitate and took off with his third brother and the prototype. As soon as he arrived at the airport, three military jeeps were already waiting there. The two of them were picked up in the same plane.

Three days later, the third brother issued an additional 10 billion US dollars in his account, but the patent had nothing to do with him.

When Lao Liu took him onto the plane, he held his hand very hard: "Ye Yuze, thank you for everything you did. I am also sorry for your father's affairs. They have their considerations on it, and it is also to protect you."

Ye Yuze smiled: "No need to explain this. I, a second generation, can do this. How could their generation care about their own honor and disgrace? As long as our country becomes more and more prosperous and strong!"

Old Liu held the third brother's hand again: "Good guy, you were almost blocked by them this time and were not allowed to leave. It is very rare for you to be like this. But considering many factors, maybe you can use your strengths more than that, so that's all."

The third brother smiled and didn't say much. Then a few people said goodbye. How could such technology be sold to other companies just be the money? But as a descendant of a military reclamation company, he had to do something for the country.

On the plane, Ye Yuze asked the third brother what he was going to do next?

The third brother pondered for a while, then firmly said: "I have many ideas on the plane engine. Ivan, and after this research, I have also gained some insights. I am going to develop a different aircraft engine."

Ye Yuze thought for a while: "You go to Germany. I have a factory that is producing turbine and engine parts for Airbus, which may be of some help to you."

The third brother nodded and agreed. He has graduated from graduate school this year, so there is no need to waste time taking any degree. It is better to devote all his energy to his career.

Airbus is currently the only company in the world that can match Boeing. Working in such a factory for a while is of great benefit to his research.

After talking to Old William and Luke on the phone, Ye Yuze did not explain the identity of the third child. The main reason is that after years of development, the current German factory has long been incomparable to the past.

He has become a very famous manufacturing company in Germany and even Europe. However, the more such a company, the higher the government's attention will be, so Ye Yuze basically does not go there.

After all, the company registered by Ye Yuze is from the British Islands and the name is from the British. Basically no one will find out that he is from the Chinese.

Ye Yuze is already considering whether he should be a US citizen? After all, doing things will be much more convenient.

After thinking about it for a while, Ye Yuze decided to wait. Although the matter of naturalization was very simple for him, he still couldn't get over the hurdle in his heart.

Once your nationality is changed, it proves that you are no longer Chinese, no matter what skin color you have or what kind of blood you are shed.

Ye Yuze did not go to see the third brother off again. He took a plane to the hamburger. Luke picked up the plane. Now Luke is married and has found a hamburger girl.
