In the next second, the "Sea Dragon Palace", which had been blown backwards by the wind, began to slow down.

"Alas???"

"What's the situation?"

"Why did you slow down?"

"Did you drop anchor? or did you hit the brakes?"

Whether it was at the scene or on the Internet, there was a sound of surprise.

And what happened next went against the intuition of many people.

The "Sea Dragon Palace", which unfolded the wave flaps and faced the headwind, not only stopped retreating, but then began to accelerate forward.

Excuse me？

What happened?

Whether it was netizens or the onlookers at the scene, they all looked confused.

"Hey, it's moving, it's moving! What's the situation?" Wang Hongchun in the room, who heard Gu Xiaobai's order, obediently sat on the sofa next to him and put on his seat belt.

Later, I found that Yan Xuexin was lying on the window watching the excitement, and he also came over.

Almost all of these living rooms are sea-view rooms, and they can see the sea outside and a "wave petal" that stretches out.

Then, Gu Xiaobai's voice came again: "At present, the first-order power navigation is being activated, and then the 'Sea Dragon Palace' will accelerate, if there is a bump in the hull, please don't panic, fasten your seat belts, and wait for the boat to stabilize......"

Wang Hongchun's eyes widened and he asked, "Could it be that the wind direction has changed again?"

Yan Xuexin looked at an anemometer not far away, shook his head and said, "No, you look at the wind direction!"

Wang Hongchun looked at the pointing of the arrow, his eyes widened, and sure enough, the direction of the wind had not changed!

"Could it be that the Dragon Palace on the Sea is actually equipped with an engine?" Wang Hongchun muttered.

How much oil does such a big ship have to burn!

"No, no, no......" Yan Xuexin frowned and thought for a moment, and then slapped his thigh suddenly: "I'll go, why didn't I expect that these waves are all ready-made curved sails! Bernoulli's Law!"

Yes, all of this comes from Bernoulli's law.

Bernoulli's law, proposed by Swiss fluid physicist Daniel Bernoulli in 1738, is actually very simple.

Because energy is conserved, the sum of the pressure energy or potential energy of the fluid decreases as the velocity of the non-viscous fluid increases.

In other words, the faster the flow rate of the fluid, the less static pressure is generated on the surroundings.

It was this simple law that led mankind to build airplanes.

The lift of an airplane is not generated by the upward tilt of the wings or other means, but by the asymmetrical curved surface of the wing, the upper wing is often bulging, and the bottom is relatively straight.

In this way, when the air flow through the wing of the aircraft, the air above takes a curved road, so the flow rate is fast, and the pressure is small, while the air below goes in a straight line and the flow rate is slow, so the pressure is large, so that because of the difference in the flow rate of the upper and lower air, a very strong upward pressure will be generated to hold the aircraft up.

In fact, many people have been surprised why such small wings of an airplane can drive such a large body, because even if the same energy is used, sprayed upwards from below, blowing the wings, it is impossible to make the plane fly, but borrowing Bernoulli's law, it can produce more powerful lift.

And now, the eighteen "wave petals" on the "Dragon Palace on the Sea" are like the wings of an airplane, except that the thrust it produces is not upward, but forward.

When the wind blows through the "wave valve" that is not symmetrical in shape and more protruding on one side, the flowing air makes the "wave valve" produce a significant pressure difference, pushing the boat forward!

This force is obviously stronger than the wind itself!

Of course, this force is not front-looking, but has a certain angle with the hull, and at the same time, under the "Dragon Palace on the Sea", several plate-like "keels" stretched out.

These plate-shaped keels, in fact, were originally designed to dampen and resist strong winds and ocean currents, and can also play an auxiliary role in the rudder at special moments.

But at this time, they obviously played a role in counteracting the lateral force, and by controlling the direction of the plate-shaped keel, the lateral thrust generated by the wind was canceled, but under this force, the "Sea Dragon Palace" seemed to be gently twisted by a hand, and it was obviously tilted.

The horizontal sensor on the ship immediately sensed the tilt of the angle and began to pour ballast water into the underwater compartment on one side, adjusting the center of gravity of the ship......

This process is manifested in the "Sea Dragon Palace", that is, the "Sea Dragon Palace" is shaking slightly.

In the bridge, Gu Xiaobai's hands were beating rapidly, adjusting the parameters of the control, and the various sensors and the motor that controlled the "wave valve" were balanced, and gradually, this shaking slowly reduced until it disappeared......

The whole ship stabilized and began to accelerate at an astonishing speed for such a behemoth!

Today, the wind in the Taiwan Strait is about level 5, that is, the speed is about 31-40 kilometers per second, and the waves at sea are light to medium.

The waves are under the light, dragging long waves, rushing forward, and from time to time there are white-headed waves.

Occasionally, there would be a splash of spray, a rattling sound, and then a tumbling and disappearing into wave after wave.

Standing on the bow of the boat, one can feel the night breeze blowing on one's face, the hair fluttering loosely, and the ropes tied to the ship shaking in the wind.

Category 5 wind, which is already not a small wind on land.

And the "Sea Dragon Palace", which opened its eighteen sails and faced the sea breeze, began to accelerate against the wind without any scientific reason!

Soon, it was speeding at more than 15 kilometers per hour, which was the speed of the previous "Sea Ryugu" when it drifted downwind.

And that's not the limit, it's just the beginning.

Because of the Dragon Palace on the sea, it is still accelerating!

Beside him, everyone on the boat was dumbfounded, and they immediately sped up to follow.

Yan Xuexin and Wang Hongchun's room, in the front of the "Sea Dragon Palace", they couldn't see anything behind, but they saw the waves pulled out by the sterns of other ships nearby, and they also knew that their speed was very fast now.

20 km, 30 km......

Until 35 kilometers of wind speed close to current are reached.

Facing the wind, how can a sailboat be as fast as the wind?

It's not scientific!

The surging waves, crushed by the "Dragon Palace on the Sea", and the "Dragon Palace on the Sea", which was moving forward with more than 20 ships of various sizes and sizes, was like a super-large aircraft carrier, driving with its own escort fleet.

"Damn, how can the sailboat be so fast, there must be some kind of engine installed in the Dragon Palace on the sea!" Wang Hongchun shouted.

Yan Xuexin couldn't hold back any longer, he opened the window, and with a "whoosh", the wind poured in, blowing the curtains and the papers and books in the room.

The two of them were like two dogs sitting in the window of a car, poking their heads out.

If they could, they might have stuck their tongues out.

"Listen!" Yan Xuexin pointed to a stretched "wave petal" not far from the window.

The hard "wave petals" tilted, like a knife, facing the direction of the sea breeze.

The wind splits at the edge of the "wave petal" and forms two air currents with a huge difference in speed, one rushing rapidly along the arc-shaped outer ring of the "wave petal" and the other flowing in a straight line inside the "wave petal".

Two air currents, vibrating the "wave valve" at the same time, produce very different pressures and two very different frequencies.

The sound of "squeaking ......" lingers above, and the sound of "buzzing ......" is below.

One high and one low.

In the distance, the wind passed through eighteen "wave petals" of different sizes and heights, as if the wind blew all the organs at the same time, turning into a magical and harmonious piece of music, vibrating people's eardrums.

Nearby, on a boat, Xu Huohuo held the mobile phone in his hand and was broadcasting live to everyone.

"Do you see, do you see? look! listen to that!"

"What's so great about riding the waves!"

"Look at us Xiaobai, against the wind and waves!"

On the "Sea Dragon Palace", Gu Xiaobai leaned in front of the microphone again: "Please note, the next 'Sea Dragon Palace' will undergo a two-stage acceleration, please fasten your seat belts, two students of C208, please don't stick your head out of the window ......"

Then, he reached out and typed in the next command.
