"Your Majesty, what is this nose-like thing called? What is it for? A designer in charge of the design of the ship's bottom ballast cabin asked Yang Wenli.

"It's called the bulbous bow, and it can significantly reduce the resistance of the seawater, which is the experience of a lot of experimentation in later generations, and all ships in later generations have adopted this thing."

"Oh! I know it, thank you, Your Majesty! Is the interior of this ballast chamber all concrete? Why not use it as a battery compartment? ”

"It's just not easy to repair and replace, if you can find a way to do it, you can do it, in short, it's a ballast cabin."

"Your Majesty, I want to minimize the weight of the ship and replace the concrete with the necessary things on the ship, I will think of a way to negotiate with the designers of the upper cabins to see if I can do it."

"Hmmm! Yes, but the rest of the part should be made of concrete, and the ballast tank should be made solid to prevent water leakage caused by scraping on the bottom of the ship.

However, it is also beneficial to have the battery in the bilge, because the lithium battery is very explosive and burning, which can reduce the risk of casualties, so I agree with your suggestion.

Sometimes, we designers have to know how to make trade-offs, weigh the pros and cons, and the pros outweigh the disadvantages. ”

"Whoa! Taught by the lowly position. ”

At this time, someone raised his hand to ask for a question, and Yang Wenli walked up to the person who raised his hand and asked him, "Is there any problem?" ”

"Your Majesty, if you find that the fumale needs to prevent seawater from backing up, please ask Your Majesty for advice."

"That's right, at the end of the nozzle to install a one-way valve, also called a check valve, it ensures that it can only be one-way, if the internal air pressure is greater than the seawater pressure, the valve is open, if the seawater pressure is greater than the internal air pressure, the valve is closed.

However, because this is a high-temperature gas, the life of the valve is limited, so the valve can only be installed in the hull for easy replacement, behind the check valve, but also to install an artificial gate, just like the dam gate, close the gate can replace the check valve, the gate is usually open. ”

"Your Majesty, why not just use an artificial gate? It also prevents the backflow of seawater. ”

"No, we can't guarantee that the internal air pressure and seawater pressure balance can open the gate, the usual situation is that the boiler is running on a fire, the internal air pressure will rise instantly, and the gate will not be opened, and it is easy to deform, so the artificial gate can only be opened at ordinary times, which is to prevent it from deforming, it only plays the role of insurance."

"Oh...... Humble duty understood. ”

"You don't have to worry about the internal structure of the one-way valve, you just give the external dimensional data, and the technician department is responsible for manufacturing. But the structure of the artificial gate is simple, you have to design it all and give precise standards. ”

……

Yang Wenli's daily work is to help his designers solve some difficult problems, and he has recruited 150 new designers, so he is actually the busiest person in the entire design team.

Although there are no complicated electronics, there are tens of thousands of parts and components in a ship, and the task of hull design is very complex and time-consuming, and the collaboration of these 150 designers can speed up the design process, but the whole winter is just like that.

The winter on Ezo Island is from the end of October to the beginning of April of the following year, which is more than four months, and in such a long time, the technical department has only assembled and debugged, and more than 200 technicians, through their efforts, finally produced the first 10-megawatt steam turbine hybrid system.

It must be noted that the director of the technical department is also Yang Liren, who is the general manager of the palace, but in the winter he became the director of the technical department, because Yang Wenli basically soaked in the industrial area all winter and did not go anywhere, so he had to change his job to become a senior technician.

On this day, Yang Liren excitedly invited Yang Wenli to accept the first steam turbine hybrid system made by the technical department: "Your Majesty, after the efforts of the brothers, it has finally been made, please take a look!" I don't know if it's okay or not, whether it's to your liking? ”

"Oh! So fast? Have you tried it? Yang Wenli replied with a smile.

This is the world's first steam turbine hybrid system, and it is the highest level of power system in the future, in terms of thermal efficiency utilization alone, the hybrid system he designed is even more advanced than the gas turbines of later generations, no wonder he is so happy.

"I tried it on startup, and it ran smoothly, so Weichen dared to ask His Majesty to accept it."

"Good! Check it out. Yang Wenli smiled and took the lead to walk forward.

When he got there, Yang Wenli did not rush to ask for the start, he first checked the fineness of the refined coal powder, grabbed a little with his hand, leaked it in the fingers, and then said to Yang Liren: "Liren, this pulverized coal is not fine enough, needless to say that your nozzle is not precise enough, the pulverized coal must be as smooth as graphite, so as to reduce the problem of the injection link, it must be improved, the finer the pulverized coal, the less the nozzle is blocked, and it is more economical to save coal." ”

"Whoa! We improve right away. ”

In addition, the operation of the entire power system is required to be fully automatic, including the crushing of coal, transportation to injection, and there can be no manual participation in the whole process, so the coal bunker should be designed into a funnel shape, using the action of gravity, entering the crusher, and directly transporting it to the nozzle after crushing.

In this, you still have to find a way, I won't look at it today, and I'll report it to me when it's done. ”

"......"

Yang Liren originally wanted to get His Majesty's praise, but he knew that something went wrong at the beginning, and he wanted to cry without tears.

Yang Wenli is very demanding, even though he uses coal with low calorific value as fuel, but he also requires the convenience of liquid fuel, and after his unique design, it is not far from modern gas turbines.

Scientific research is like that, sometimes you are full of confidence, but then something goes wrong, and you have to find the problem again and solve it.

Don't look at Yang Wenli's requirements are only a few words, but it is not simple at all, it is very simple to make the coal bunker into a funnel shape, and it is not difficult for the coal to be crushed into graphite as delicate, in terms of precision technology, they have fifty ninth-level technicians, and the precision process is not weaker than modern centimeters, the difficult thing is the transportation and injection link, no matter how fine the coal powder is, it is not liquid after all, they have to find a way to solve this problem, which is enough for them to be busy for a while.

In any case, the power system is almost successfully developed, and there will not be much change, Yang Wenli remembered that last year Ono Taro applied for the establishment of a modern civilian shipyard.

At the beginning of April, when the spring was warm and cold, Yang Wenli made a special trip back to the palace and summoned Ono Taro to inquire about the progress of their shipyard.

Because there are too many scientific and technological secrets in the industrial zone, outsiders are strictly forbidden to enter, so he does not want to meet Taro Ono in the industrial zone, so as not to take the lead in breaking the rules.

Ono Taro hasn't come yet, but Xiao Yan'er heard the news first.

"Your Majesty, why did you come back so early today?" Xiao Yan'er asked him with a look of surprise.

"I'm going to meet someone today, what? Aren't you fun alone? Can I go to spring? ”

"Am I not? It's so cold outside, let's talk about it later! ”

"Not necessarily, now there are greenhouses in the countryside, which are as warm as spring, and all kinds of vegetables and rice seeds are planted, which are very beautiful, and it is also very necessary for you to visit the rural grassroots as the mother of a country."

"Really? Then I'll go and take a look, or your majesty will come with me!" ”

"No, no, no, no! I don't have time, you can only go alone. ”

"Alas! It's boring, you're always busy. ”
