Eagle Sauce: The 055 destroyer was launched into the sea just after the founding of the country?

"Actually, I had already thought about this matter before coming here."

Seeing Li Zifeng's embarrassed expression.

Fang Yu then spoke slowly.

"Mr. Li, I've taken the liberty of coming here this time. I actually brought two gifts for our Dalian Shipyard."

"One of them you have already seen is the 2000-ton gantry crane."

"And the second thing is what we are talking about..."

"Director Fang, are you saying... that you designed a new power system for this ship?"

Hearing this, Li Zifeng felt like he had become a complete illiterate.

Suddenly there was a kind of

The feeling of "I don't understand what the other person is saying, but I'm deeply shocked"...

No.

Although I know that you, Fang Yu, are very capable, but this is a bit too much!

That's a power system! You said you could research it and figure it out?

Seeing Li Zifeng's shocked expression, Fang Yu just laughed.

Then, he took out his new power design drawing and handed it to Li Zifeng.

"Boss Li, this is the power system I designed specifically for the Arsenal Ship. Please review it!"

Upon hearing this, Li Zifeng took the design draft without any further greetings and began to read it attentively, fearing that he would miss a page.

But after just one glance, he raised his head in surprise and looked at Fang Yu as if he was looking at a freak.

As if he had known that Li Zifeng would have this reaction, Fang Yu still looked at him with a smile and made a gesture for him to continue.

When Li Zifeng saw this, he frowned and continued to look at the drawing.

However, the more I looked at him, the more his brows furrowed.

In the end, it even wrinkled into the shape of a "川" character.

It’s no wonder that Li Zifeng was so shocked. It was because the power system designed by Fang Yu was so unique.

The system designed by Fang Yu is completely different from the power systems currently used on all warships.

The power system used by most warships nowadays is a steam turbine.

To put it bluntly, it is to boil water in a boiler.

The steam turbine first uses the high-temperature and high-pressure steam generated by combustion to drive the impeller to rotate, and generates work through the impact force of the steam on the impeller.

Then, the high-pressure steam enters the turbine and enters the impeller chamber, driving the blades to rotate through the impeller's sealing structure, thereby generating kinetic energy and driving the equipment on the shaft to work.

The advantages of this steam turbine are.

Since high-temperature and high-pressure steam can be used to directly drive the impeller, its efficiency is relatively high.

The steam turbine adopts a closed cycle working mode. Through multi-stage expansion, it can fully utilize the thermal energy of steam, resulting in less energy loss and higher efficiency.

Therefore, since its birth, this type of steam turbine has been widely used by navies of various countries on their warships.

The power system designed by Fang Yu was quite imaginative, replacing the steam turbine with a gas turbine.

Although these two power systems only differ by one word.

But the working principle has undergone a qualitative change!

A gas turbine uses a mixture of gas and compressed air to burn in a combustion chamber, generating high-temperature and high-pressure gas to drive the impeller to rotate, thereby generating work.

Specifically, fuel gas and compressed air are compressed by the compressor of the gas turbine and then enter the combustion chamber for combustion. The high-temperature and high-pressure gas after combustion drives the impeller of the turbine to rotate, driving the equipment on the turbine to work.

One uses steam, while the other uses air directly to do work.

In Li Zifeng's opinion, this gas turbine does not seem to be designed specifically for warships.

On the contrary, this power source seems to be modified from other weapons.

In fact, Li Zifeng was not wrong on this point.

The working principle of the gas turbine system is similar to that of a turbofan engine.

In addition to providing power to warships, it can actually be installed on some large aircraft to provide power for the aircraft.

As a veteran shipbuilder, Li Zifeng thought about it.

I also immediately understood some of the advantages of this gas turbine.

The working principle of steam turbine power generation is to use the steam generated by boiling water to push the blades of a steam turbine. This is the power that propels large warships forward.

To achieve this, hot water in multiple boilers throughout the large warship must be heated to boiling point, forming high-density water vapor.

Then let the water vapor be evenly distributed throughout the large warship until the entire large warship can emit enough energy and start sailing normally.

This is precisely the disadvantage of steam turbines.

Using this power system, it usually takes more than ten hours or even dozens of hours for a large warship to go from a stationary state to fully start.

In order to save startup time, many ships even keep their steam turbines running at all times when they are docked.

This will not only cause unnecessary consumption of oil, but also cause unnecessary wear of parts.

However, the gas turbine designed by Fang Yu does not have this shortcoming.

Because the working principle is completely different, gas turbines do not need such a long warm-up time at all.

Take one of the Eagle Sauce’s aircraft carriers as an example.

If you want to get it moving, you need to preheat the steam turbine for 48 hours.

After switching to gas turbines, it only takes two hours to start up the aircraft carrier and bring it to full speed.

Not only does it greatly shorten the startup time of the aircraft carrier, but it also allows it to be docked at the port without having to keep it in the startup state due to the long startup time.

Greatly saves fuel consumption and parts wear...

When Li Zifeng thought of this, an idea immediately emerged in his mind.

The power system designed by Fang Yu will probably bring an unimaginable impact to the naval construction of the entire Blue Star.

I'm afraid from now on.

The steam turbine, which has been used from World War I to the present day, is about to be completely consigned to the dustbin of history...

But, at this moment.

Li Zifeng suddenly seemed to realize something, and his originally relaxed brows suddenly frowned again.

Because he suddenly discovered.

The gas turbine system designed by Fang Yu is good in every way.

But there is one thing.

As an internal combustion engine, the thermal efficiency of this system is even lower than that of a steam engine!

The thermal efficiency of this gas turbine is only 36%.

You know, even the steam turbines made by Longguo with current technology have a thermal efficiency of over 40%!

Not to mention the steam turbines of the Eagle Sauce family.

I'm afraid the thermal efficiency can reach a terrifying 45%...

And just this one point is enough to turn this gas turbine technology from a hot commodity into something that no one cares about.

After all, the higher the thermal efficiency, the greater the horsepower the power system can provide.

It is also a power source.

A steam turbine can provide the warship with 45000 horsepower, while a gas turbine can only provide it with 36000 horsepower.

Don't underestimate this more than 10,000 horsepower.

These two power systems are placed on the same boat, but they can make it reach a speed difference of more than 10 knots!

When the two sides are fighting, even a knot of speed can determine the life or death of a fleet.

Therefore, no matter how many advantages the gas turbine has, its only drawback is that its thermal efficiency is too low.

It is enough to sentence this power system to death...
