Chapter 871 Breaking Against the Wind and Waves! (three more)

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

"Ugh???"

"what's the situation?"

"Why did you slow down?"

"Did it drop anchor? Or hit the brakes?"

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

And what happened next is even more contrary to the intuition of many people.

The "Sea Dragon Palace" that spread out its wave petals and faced the headwind not only stopped retreating, but then began to accelerate forward.

Excuse me?

what happened?
Whether it is the netizens or the onlookers at the scene, they all look confused.

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

Later, I found Yan Xuexin lying on the window to watch the excitement, so he also came over.

These living rooms are almost all sea view rooms, and they can see the sea outside and a "wave petal" stretching over.

Then, Gu Xiaobai's voice came again: "The first-order power navigation is currently being activated, and the 'Sea Dragon Palace' will speed up next. If there is a bump in the hull, please don't panic, fasten your seat belts, and wait for the ship to stabilize. ..."

Wang Hongchun stared wide-eyed and 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, look at the wind direction!"

Wang Hongchun looked at the direction of the arrow, his eyes widened, and the wind direction did not change!
"Could it be that the Sea Dragon Palace 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, then slapped his thigh suddenly: "I'm going, 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 was proposed by Swiss fluid physicist Daniel Bernoulli in 1738, and its content is actually very simple.

Because of energy conservation, as the velocity of an inviscid fluid increases, the sum of the fluid's pressure energy or potential energy decreases.

In other words, the faster the flow rate of the fluid, the less static pressure will be exerted on the surrounding area.

It is this simple law that allows humans to create airplanes.

The lift of an aircraft does not come from the upward tilt of the wings or other means to generate lift, but from its asymmetrically curved wings. The upper wing is often swollen, while the bottom is relatively straight.

In this way, when the airflow passes through the wings of the aircraft, the air above takes a curved path, so the flow velocity is fast, and the pressure is small, while the air below follows a straight line, the flow velocity is slow, so the pressure is high, and this will be caused by the up and down air. The difference in flow velocity produces a very strong upward pressure, which lifts the aircraft up.

In fact, many people have been surprised why such a small wing of an aircraft can drive such a large body, because even if the same energy is used to spray upwards from the bottom and blow the wings, it is impossible to make the aircraft fly. Bernoulli's law, but can produce a stronger lift.

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

When the wind blows over the "wave petals" that are asymmetrical in shape and one side is more protruding, the flowing air makes the "wave petals" produce a significant pressure difference, pushing the boat forward!
This force is obviously stronger than the wind itself!

Of course, this force is not facing forward, but has a certain angle with the hull of the ship. At the same time, several plate-shaped "keel bones" protrude from the bottom of the "Sea Dragon Palace".

These plate-shaped keels were originally designed to stabilize and resist strong winds and ocean currents. In special moments, they can also serve as auxiliary rudders.

But at this time, they obviously played the role of offsetting the lateral force. By controlling the direction of the plate-shaped keel, they offset the lateral thrust generated by the wind. However, under this force, the "Sea Dragon Palace" seemed to be gently twisted by a hand. After a while, there was an obvious tilt.

The level sensor on the ship immediately sensed the inclination of the angle, and began to inject ballast water into the underwater compartment on one side to adjust 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.

On the bridge, Gu Xiaobai's hands were beating rapidly, adjusting the control parameters, and the various sensors and the motors controlling the "wave petals" achieved a balance. Gradually, the shaking gradually eased until it disappeared...

The whole ship stabilized and began to accelerate at an astonishing speed for such a huge monster!
Today, the wind in the Taiwan Strait is about force 5, that is, the speed is about 31-40 kilometers per second, and the waves on the sea are small to medium waves.

Under the lights, the waves are dragging long waves, rushing forward, and white-headed waves appear from time to time.

Occasionally, waves splashed and made a sound of rushing, and then surged and disappeared in one wave after another.

Standing on the bow of the boat, one can feel the night wind blowing on his face, his hair fluttering in a mess, and the rope tied on the boat trembles in the wind.

The fifth-level wind is already not a small wind on land.

But the "Dragon Palace on the Sea", which opened up eighteen sails to face the sea wind, began to accelerate against the wind without any scientific reason!
Soon, its speed exceeded 15 kilometers per hour, which was the speed of the previous "Sea Dragon Palace" when it was drifting downwind.

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

Because the Sea Dragon Palace is still accelerating!accelerate!
Beside, everyone on the boat was dumbfounded, and they immediately sped up to follow.

The rooms of Yan Xuexin and Wang Hongchun are in the front of the "Sea Dragon Palace". They can't see what's going on behind them, but they can see the waves pulled from the stern of other nearby ships, and they know that their speed is already very fast.

20 kilometers, 30 kilometers...

Until it reaches 35 kilometers close to the current wind speed.

Facing the wind, can the sailboat be as fast as the wind speed?

This unscientific!

The turbulent waves were crushed by the "Sea Dragon Palace", and the "Sea Dragon Palace" was driving forward with more than 20 ships of various sizes, just like an oversized aircraft carrier, leading its own escort fleet drive.

"Damn it, how could the sailboat be so fast, there must be some kind of engine installed in the Sea Dragon Palace!" Wang Hongchun yelled.

Yan Xuexin couldn't bear it any longer, he opened the window, and with a bang, the wind came in, making the curtains and the papers and books in the room rattle.

The two of them poked their heads out like two dogs sitting in a car window.

If they could, the two of them might stick their tongues out.

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

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

The wind is split at the edge of the "wave petals" and turned into two airflows with huge speed differences, one rushes along the arc-shaped outer circle of the "wave petals", and the other flows in a straight line inside the "wave petals".

The two streams of air vibrate the "wave petals" at the same time, producing completely different pressures and two completely different frequencies.

The sound of "squeak..." lingered above, and the sound of "buzzing..." was below.

One high and one low.

Further away, the wind passed through eighteen "wave petals" of different sizes and heights, like the wind blowing all the pipe organs at the same time, turning into a magical and harmonious piece of music, shaking people's eardrums .

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

"Did you see it? Did you see it! Look! Listen to that!"

"What's so great about riding the wind and breaking the waves!"

"Look at our Xiaobai, we are going against the wind and breaking the waves!"

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

Then, he reached out and typed the next command.
