Zhu Zhongliang walked around the artillery factory in Jiangnan, visited all kinds of artillery and turrets, and chatted with the craftsmen.

Before leaving, he sent a batch of red envelopes and condolences to the craftsmen, and went to the machine furnace factory the next day.

Artillery can only be used on artillery ships, while engines and boilers can now be used on all ships.

At the same time, both the boiler and the turbine are in the stage of disruptive innovation.

The original large water pipes, coal-fired boilers, and reciprocating steam engines have entered a complete phase-out process.

In the future, all new warships will use small-tube oil-fired boilers with steam turbines.

Zhu Zhongliang first went to see the power system that was ready to be used on the new aircraft carrier and battleship.

Thirty-four years before Taepyeong, the system was still in the laboratory stage.

None of the people in charge of the research themselves thought that they needed to be turned into the main power systems immediately.

There were not many researchers in charge of the project before, and there were no clear goals and progress for the work.

It is to continue to try and explore to find the most suitable design solution, reduce the failure rate, and improve stability.

At the beginning of the 34th year of Taiping, Zhu Jingyuan asked all new ships to switch to this system.

It is only the design and production planning of the relevant system that becomes the most important task to be completed within the deadline.

In the three main industrial chains of the mainland, the personnel of coal-fired large water-tube boilers and reciprocating steam engines, except for the necessary personnel to maintain the problems of the existing ship power system, most of the others have been transferred to this project.

The three parts of the crew gathered in Suzhou Mansion and first drove out the power systems of destroyers and cruisers as quickly as possible.

Under normal circumstances, the construction period of a 3,000-ton destroyer takes one year, and it takes two years from the start of construction to the end of service.

[In other words, it is the best way to read aloud and listen to books at present, @

Of course.

"Moreover, the power of a coal-fired boiler depends on the bottom area of the furnace, and the power of an oil-fired boiler depends on the volume of the combustion chamber.

"The boiler plane has become three-dimensional, so the oil-fired boiler can increase the power of a single boiler more conveniently."

The master craftsman immediately exclaimed:

"What Your Majesty said is very true, and this is the truth.

"Oil-fired boilers really surpass coal-fired boilers in an all-round way, and they are comprehensively leading in terms of actual performance and convenience of supply.

"So the boiler we prepared for the 40,000-ton warship has also been adjusted again.

"Continue to scale up the volume of the individual boilers while trying to pressurize the closed combustion chamber.

"To ensure the stable output of 8,000 horsepower power from a single furnace, and to use 16 boilers to achieve 30 knots of 40,000 tons of warship.

"Strive to achieve a stable output of 10,000 horsepower for a single furnace to meet the power demand of a 60,000-ton and 30-knot warship.

"The next further plan is to hit a single boiler with 20,000 horsepower and use eight boilers to achieve the goal."

Zhu Zhongliang listened to the craftsman's somewhat excited description, and said with a little reminder:

"It's better to be conservative when it comes to pressurization.

"It's better to do a land experiment first, and don't put it in the belly of the ship right away, because it's hard to disassemble if you put it in.

"And the 60,000-ton battleship is still early, don't be in such a hurry, just take your time."

The craftsmen immediately agreed, promising to be careful, and to do land experiments first to ensure stability before boarding the ship.

In fact, even if Zhu Zhongliang didn't remind him, the craftsmen would do the land experiment first.

But now there is no need to be serious with the Emperor Taishang in this kind of place.

The old man's reminders are also well-intentioned, and everyone understands it.

Zhu Zhongliang stayed at the machine furnace factory for two days, and then went to the aircraft factory that he was most concerned about.

First, we went to see the traditional factory of the Royal Flying Machines Company in operation.

I went to see the assembly line factory under construction of Daming Airlines.

Finally, we visited the nearest military airfield.

They also observed the exercise of road-based aircraft simulating an attack on a ship on the surface.

Watch as planes drop bombs in the air and aerial torpedoes above the water.

Zhu Zhongliang, like the people in the military, was greatly shocked.

Zhu Zhongliang felt that the kind of warship he was looking forward to would soon be truly realized.

When the two official aircraft carriers are built, the performance of the aircraft will be further improved.

By then, it should already be possible to achieve an air strike over the ocean. ….

But the aircraft carrier is about to be fully formed, so why does the kid insist on building a large gunboat?

Zhu Zhongliang thought about it for a while, and when he had time in the evening, he personally wrote a telegram.

While expressing his thoughts more casually, he also wrote down the questions accumulated during his visit to Jiangnan and sent them to Zhu Jingyuan, who was thousands of miles away.

After Zhu Jingyuan saw his grandfather's telegram, he also fell into a short period of contemplation.

Under his own promotion, Daming's technology has progressed a little fast......

It's also because I thought I was going to leave Kyoshi, so I had a lot of things for the craftsmen.

In fact, the threshold for many designs in history is not high, the key is to have someone think about what should be done, and find the key points to achieve these designs, as well as the most important direction.

And this information is the greatest advantage of the traverser.

Even if the traverser doesn't understand too many technical details, even if he simply guides the direction and leaves the specific design and exploration to local craftsmen, he can also make science and technology improve by leaps and bounds.

Fully enclosed combustion chambers and booster boilers were a French specialty during the Second World War.

The power density of the French boilers of World War II was strong and had no friends.

Richelieu-class battleships with six boilers providing 150,000 horsepower and a total power system weight of 2,800 tons.

big

The He-class battleships, twelve boilers provided 150,000 horsepower, and the total weight of the power system was 5,300 tons.

This is a gap that approximates a direct doubling.

After World War II, fully enclosed combustion chambers were basically popularized in boilers, while booster boilers were mainly inherited in the Soviet and Chinese systems.

When Zhu Jingyuan introduced the idea of the boiler system, he only mentioned this direction more casually.

Unexpectedly, the craftsmen have become a formal technical route, and they are about to implement it.

If you look at it this way, maybe 60,000 tons of aircraft carriers and battleships don't need to wait until ten years later.

Finally, regarding Zhu Zhongliang's question, Zhu Jingyuan thought about it carefully, how to explain it to the old man:

About 420 mm shells, at the current level, they can be used with a weight of 1100 kg.

But in order to exert the maximum power of this caliber, it is better to increase it to more than 1300 kg as much as possible.

1500 kilograms is an ideal goal, in line with the idea of seeking the upper to get it, and seeking the middle to get the bottom.

As for the logic that aircraft carriers are about to basically mature, but they still have to continue to build battleships.

For a long time to come, it will still be difficult for aircraft to obtain the "ability to be on the front line at any time".

Battleships can maintain a presence on the front line at all times, ready to shell targets that need deterrence.

As you know, the norm of war is not to fight each other in the face, but to threaten and counter-threaten each other as the norm.

War itself is not the norm, and providing deterrence in a non-war state is also an important task of weapons.

These similar jobs will be done much better by battleships than aircraft carriers at present.

And for the time being, the aircraft can no longer operate at night and in bad weather.

The plane can choose to go out and hit others when the weather is good, but there is no way to keep yourself from being beaten on a rainy day for the time being.

If, in this state, the aircraft carrier meets the battleship alone, it will be ugly to die. ….

Therefore, the Governor's Office should formulate operational norms, and aircraft carriers must be accompanied by battleships when they go out.

Of course, technology is constantly developing upward, and when the aircraft carrier no longer needs the daily accompaniment of the battleship, I will take the initiative to call for an armistice in the design and construction of the battleship.

Zhu Jingyuan finished writing the reply, checked and repaired it again, and handed it over to the book to send to Zhu Zhongliang.

Then he raised his head and looked at Liu Muyun who was sitting next to him.

This usually smug girl has become a little squirming in the past two days.

I've been by my side, but I don't talk much.

This seems to be on the mind.

Zhu Jingyuan didn't know how to talk to girls, so he asked more seriously and directly:

"So, what the hell is going on? Is there something you want?"

Liu Muyun hesitated for a while, and finally lowered his head and said the truth:

"Your Highness...... My menstrual period has not come, it should be over according to the time, and there is still no movement at all, and I am hesitating to see a doctor......

Zhu Jingyuan was stunned for a few seconds, and then reminded in a daze:

"The menstrual affair does not come at all, is there a possibility that you have a ......?"

Liu Muyun actually thought of this possibility, but he was a little unable to accept this result:

"It can't be so fast, I'll just follow ...... I had a room with His Highness once......

Zhu Jingyuan was also very surprised that he might have a child:

"It's been unbelievable, but I can't think of any other possibility.

"We're probably going to have children, aren't you happy as a mother?"

Liu Muyun said rather melancholy:

"It's not that I'm unhappy, I just think it's a loss like this, just once, how can it be like this."

Zhu Jingyuan quickly understood Liu Muyun's mentality, and then couldn't help laughing:

"I also feel like it's a loss, but we have time in the future.

I have to inform my mother of this important matter."
