After Da Liang completed his junior ship design experience, he once planned to acquire the intermediate ship design skill book.

However, Keith asked Da Liang not to use skill books to improve the design level of ships, and now listening to him say this, it turns out that improving the design level of skill ships is not the only way to improve the design level of skill ships.

It's just that......

"Mentor, is there any difference between using the Intermediate Ship Design Skills Book to advance and advancing in the Ship Seminar?"

Guise replied, "The structure of a brig is much more complex than that of a sloop, and the chance of generating a base diagram is greatly reduced. Even if the proficiency level of an intermediate ship is at full level, there is less than a 10% chance that a blank blueprint will spawn a brig.

Ship structure sketches can improve the chances of drawing, but the complex structure of a Brig class makes it more difficult to simplify it. If you want to achieve a 100% completion rate with the most simplified drawings, you need to improve the success rate of the foundation.

Becoming an Intermediate Ship Designer through the Intermediate Ship Design Skill Book has a small basic success rate, and if you can be promoted to an Intermediate Ship Designer by the Master Ship Design Workshop, your basic success rate will increase by 10%.

If you can earn the Ship Master Medal, the base success rate will increase again, and there will be other benefits. ”

An intermediate ship designer who uses the Intermediate Ship Design Skill Book to advance can only achieve a drawing rate of less than 10% even if he has completed his proficiency training, what kind of sad value should be the initial value when he first starts practicing proficiency?

It can be said that without mastering a ship design sketch that effectively increases proficiency, there is no need to think about training ship designers.

If you can't get the proficiency up, the mentality will collapse first.

Since Da Liang spends so much time studying ship design, he must not be an ordinary ship designer, and the promotion of intermediate ship designer must be obtained at the ship design seminar.

And the Ship Master Medal should also be obtained as much as possible.

The ship design workshop will not be delayed because of the big news, so the trip to the Dead Realm can only be postponed for a while.

In addition, Da Liang thinks that Keith is also sullen enough.

When I got the invitation that day, I didn't say anything, as if Qinggao didn't care about it.

In fact, I was thinking about how to earn face for myself at the seminar. He himself has a problem with his head, and he can't come up with something that will surprise those ship design masters in advanced battleship design, but if a disciple can be generous at the seminar, his face as a master must also shine.

This explains why Guise is so eager to train Da Liang and let him independently complete the design of a new sloop.

Thinking of the design of the dhow, Da Liang said: "Mentor, what kind of research have you done on the design of the bulbous bow to reduce the lateral resistance of the ship?" ”

When it comes to the bulbous bow, Guise finally gets a little excited: "Your assumption about the weakening of lateral resistance in the bulbous bow is very correct, and it is even more clever than my previous research. Not only sloops, but also battleships can use bulbous bows to speed up.

However, I can't give up my previous research on the structure of battleships, as long as I can figure it out, we can not only design second-class battleships, but also make fifth-, fourth, and third-class battleships greatly improve their speed and performance, and we can make the world truly enter the era of giant ships and cannons. ”

Da Liang asked, "Mentor, have you already designed a bulbous bow that increases the speed of a dhow?" ”

Gise began to draw on the blackboard and said, "This is just one of my initial designs, and I expect it to increase the speed of the dhow by 7%. But this is not the most perfect design, which should increase the speed of a dhow to 11%, or even more. But I'm not going to waste my time on increasing the speed of the sloop, I'm going to use the bulbous bow for my new design, and I'm going to need to do the recalculations and diagrams. ”

Is Guise designing a new ship? But he didn't say much on this topic, and began to teach Da Liang about the design of the bulbous bow of the dhow.

"First of all, since we were going to use the bulbous bow to form a reverse current to balance the lateral drag, we needed a sharper bow to cut through the current.

Originally, the steering force of the hull would be weakened by the over-pointed bow, but we could use a 'U' shaped bulbous bow to increase the steering force, so that the bow change would not affect the steering force of the ship.

I designed this 'U' shaped bulbous bow to be 20 centimeters below the water line, and from here it forms a curve to the opposite side of the water flow......"

Da Liang listened carefully to Guise's explanation, he had laid a solid foundation for the design of the dhow, and even downloaded many books on the structure of the ship from the Internet to study when he was on the boat and in a hurry.

Although modern ships and sail wooden ships are very different in design and construction due to different materials, there are also many things that have been figured out, especially the changes in the mutual forces between the hull and the current, which correspond to what Giss is talking about now.

Therefore, when Da Liang listened to Guise's explanation, he also gave birth to his own ideas.

For example, Da Liang can see that according to Guise's current design, the top speed of the dhow can be increased, but in the process of acceleration, the position and shape of the bulbous bow will cause the reverse current to form a vortex, causing the hull to increase and slow down the acceleration process.

The solution should be to shorten the length of the bulbous bow, increase the upward arc of the rear half to increase the stability and impact of the current, and if the water flow is reversed, the lateral resistance can be turned into forward thrust......

Thinking too much, if Guise didn't help calculate the data, this would definitely not be a design that Da Liang could complete in a day or two.

Now for Da Liang, it only needs to make some modifications to the "U" shaped bulbous bow.

With the ready-made data provided by Gise, Daliang only needs to make modifications on this basis, which saves a lot of time.

Two days later, Da Liang sketched a dhow with an added bulbous bow, and then the most crucial step was to use his ship design skills to produce drawings that could be recognized by the system and built in the shipyard.

With anticipation and a sense of gain and loss, Da Liang chose to use the skill ship design in front of the sketch.

Mapping begins.

The system began to add lines to the sketches made by Da Liang, and time passed little by little, until the end no one knew what would come out in the end.

"Ding, you get a dhow blueprint"

"Ding, because the attributes of the dhow you designed surpass the basic model of the dhow, the system determines that this type of dhow is your exclusive model, and when you make the dhow blueprint in the future, you can choose to generate the basic model or the proprietary model, please name your proprietary model sloop."
