The reason is. If the idea is wrong, you will naturally not be able to get out. So the solution to this problem is actually very simple, just remove the original function of lifting water when the car rolls over.

Of course, from the perspective of God, you will feel that this one is also a fool, and that one is also a fool. Why can't you think of such the simplest and most basic things? But in fact, in the history of China, most of the inventions and creations are just these "

"Idiots" and "idiots" continued to persevere in their studies after being beaten to death, and this was how China's splendid civilization came to be.

Ma Jun was anxious to make the changes himself, but was stopped by Fei Qian, "Just leave this matter to the craftsmen... Come here, let's take a look at other things..."

Fei Qian didn't have time to stare at the Kunming Lake shipbuilding workshop every day. Since he came here, he naturally made the most of it to see if there was anything that could be improved.

Come on, if you don't want to find Du Niang who is getting richer and richer, how many people can really understand the difference between the ships of the Han Dynasty and the wooden ships of later generations? In other words, it is worse than the Song Dynasty and the Ming Dynasty.

What components or structures?

There are keels, watertight cabins, planks, parapets, oars, oars, rudders, sails, anchors...

It seems that the ships of later generations also exist if they exist now, and it seems that the ships of later generations also exist now.

Fei Qian walked slowly around the ship, and then stood in front of the sail mast.

The sail mast is very straight and high.

The sails under it are piled up in layers and piled up under the mast.

Fei Qian pointed to the sail and said, "Pull it up and take a look..." There was no wind in Kunming Lake at the moment, so there was no big problem in just pulling it up.

It is a very traditional rectangular sail, fixed by five or six crossbars and ropes in the middle of the sail. Although Fei Qian standing on the boat did not feel any wind, there was still some breeze flowing in the air after it was pulled up, supporting the sail.

It has to be a little puffed up.

"Okay, let's put it down..." Fei Qian noticed that the upper and lower crossbars of the sail cannot be moved, which means that the sail can actually achieve its greatest effect when the wind is downwind. Usually, paddles are used.

There are mostly oars, so the Battle of Chibi happened. Did Kong Ming have to borrow the east wind?

The use of wind power to propel ships can be said to be the most practical, effective and far-reaching navigation technology invention invented by mankind. The development of Chinese sails has similarities and differences with other civilizations in the world.

As we all know, the best wind is from the stern of a ship, because it is a tailwind, and tailwind is the best direction for a ship to absorb wind. This is the most commonly used Chinese wishing phrase "bon voyage" and "smooth sailing".

However, the wind in nature comes from all directions. When the wind is against the wind, the wind becomes a resistance to the ship's progress. Therefore, the ships of the Han Dynasty could only furl the sails and use human power instead.

If you want to make full use of the wind coming from the side, the direction of the sail must be adjustable, that is, it must be at a certain angle with the incoming wind, and then it can generate a force perpendicular to the wind direction, which can be broken down into moving the ship forward.

thrust, so it is required that the sail should be movable and can be adjusted according to different wind directions...

So when Fei Qian told Ma Jun about this idea, Ma Jun suddenly felt like he had found a treasure. He immediately called a few craftsmen to start improving the sail, and then followed Fei Qian closely to see if he could get it from Fei Qian.

I can get some other pointers there.

But it is a pity that Fei Qian himself is only half a bucket of water. All his impressions about wooden boats come from the Internet and movies of later generations. He actually knows nothing about the actual practice, so after two more rounds, there is no follow-up inspiration.

, we can only give up here and wait until Ma Jun produces the improved 2.0 version of the vehicle and ship and then take a look at it.

When Fei Qian and his party returned to the Hussar General's Mansion, as soon as they got off their horses, Fei Qian saw the waving flag at the front gate of the Hussar Mansion. Suddenly his heart skipped a beat, and he remembered something again, and frowned.

I seem to have seen somewhere that the suitability of a jib is higher than that of a jib?

"Husband..." Huang Yueying walked to Fei Qian and asked, "What's wrong?"

"Look at those flags..." Fei Qian pointed to the big flags in front of the government office, "Do they look like sails? The wind should be the same size at this time, and the two flags are about the same length, but why?

The four-cornered flag moves slowly, but the pennant moves quickly? What would happen if the ship also used a triangular sail?"
