At two o'clock in the afternoon, the two cruisers set sail with their three hundred crew members. The destination is Hangzhou.
This time, the main purpose is to test the seaworthiness of the ship. After all, this cruiser is different from previous ships. The invention of the cruiser was a type of ship designed for ocean voyages. It is a special ship used to patrol overseas colonies.
A cruiser is a large surface ship with strong firepower and multiple uses, mainly operating in the ocean. Cruisers are equipped with strong offensive and defensive weapons, have high speed and seaworthiness, and can conduct long-term ocean operations under harsh weather conditions.
It can carry a large amount of supplies, maintain self-sustainability for a long time, and patrol colonies around the world.
The Great White Fleet, composed of two ships, raised its full sail on the sparkling sea. Driven by the strong northwest wind, the sails swelled and drove to a high speed of 21 knots. Then sailing on the sea like lightning.
The ship sailed very steadily, far exceeding Yang Fan's expectations.
Because the hydrodynamic shape of this ship is of modern design, we also contacted the water tank of the Ship Research Institute to optimize the hydrodynamic design.
The reason why it can sail so smoothly at high speeds is because the design drawings include stabilizer fins and bilge keels, two things that do not belong to this era.
Fin stabilizers are the most effective anti-roll devices. It can not only reduce the rolling, but also increase and intensify the rolling of the ship, and is used to train the crew's vomiting tolerance to adapt to high sea conditions.
Generally, stabilizers are installed at the bilges on both sides of the ship, with a wing-shaped cross-section, also called side rudders. By rotating the anti-rolling fin through the control mechanism, the water flow exerts force on it, thereby forming an anti-rolling moment and reducing the sway, so as to reduce the roll of the hull.
The effect of this equipment depends on the speed. The higher the speed, the better the effect. Therefore, it is mostly used on high-speed ships. Yang Fan’s flying shear ship is the fastest ship type in this era, so it is very suitable for installation.
There are two series of fin stabilizers: retractable fin stabilizers and non-retractable fin stabilizers. Considering the technical level, Yang Fan only equipped fixed, non-retractable fin stabilizers.
Vessels equipped with fin stabilizers. It can improve the safety of ships and improve the seaworthiness of ships. Improve working conditions on board and increase crew efficiency.
If it is a warship, under high sea conditions, Yang Fan's crew can maintain combat even when the enemy is severely seasick. This is very beneficial.
A stable ship can avoid cargo collision and damage. Improve the ship's speed in wind and waves, save fuel, and extend the service life of other ship equipment. For Yang Fan, although the investment is high, it is still very cost-effective in the long run.
The bilge (pronounced Bi) keel is a continuous profile (similar to the side strips of an airplane) installed on the bilge of the ship (that is, the linear part connecting the side of the ship and the bottom plate). Generally installed on ships with a small square coefficient to enhance seakeeping and stability.
With reasonable design, roll and pitch can be greatly reduced. But it will also reduce the maneuverability of the ship accordingly. The length of the bilge keel is generally 1/3 to 1/2 of the length of the ship's length, and its structural forms include single plate and double plate.
Yang Fan stood on the bow of the ship, feeling the sea breeze. It felt so good to ride the wind and waves on a clipper ship, quite like the flying feeling of the Titanic.
Driving on land, the speed is more than 21 knots, which is only 39 kilometers per hour. However, it feels really fast on the boat. The bow of the ship broke through the waves, causing a huge swell. It's very exciting. It feels like driving a go-kart. It's not that fast, but it's super exciting because it's so close to the ground.
"Master, I'm so excited. I didn't expect the clipper boat to be so exciting. It almost feels like it's about to fly." Chen Xi hugged one of Yang Fan's arms, leaned against him, and said with a flushed face. "Ah sneeze!"
Seeing Chen Xi sneezing, Yang Fan said: "The wind is strong in winter, it's better than catching a cold. Let's go back to the cabin."
Chen Xi had been extremely cold for a long time, but it was a pity that the master was suffering from hysteria while standing here, and she couldn't bear to leave, so she could only hold on.
"Okay, okay, Ah Zhi!"
Yang Fan smiled bitterly, how could he not know Chen Xi's little thoughts. He even saved her. Girls in this era care about this very much.
Of course, if you look at your benefactor, he is handsome and handsome.
Talent, young and rich. The natural next step is that the young lady has nothing to offer in return and is willing to give herself to him. If the benefactor is ugly, vulgar and uncivilized, and his family is in ruins, then the next step should be that the little girl has nothing to repay and is willing to be a cow or a horse in the next life to repay the great kindness.
Yang Fan naturally belongs to the former kind.
Returning to the living deck and coming to the dining room, Yang Fan asked the cook to cook Ginger Cola and asked Chen Xi to get rid of the cold. At such a young age, his clothes were soaked by the mist, but don't get rheumatism, which will last a lifetime.
Watching Chen Xi warm his hands with a stainless steel cup with his little hands that were red from the cold. He stretched out his pink tongue and tested the temperature first. The sweetness of Pepsi made Chen Xi squint his eyes happily.
Then sip, sip. Apparently this drink was to her liking. Next to the master, the little beauty Chen Xi was in a beautiful mood and felt a little lucky.
There are always good things here. She is always discovering delicious and fun things.
I have never had this drink called Coke. Madam arranged for her to come here this time, so she had to enjoy it.
"Master, where are we going to go to sea for a few days this time?" Chen Xi felt that after drinking a cup of ginger cola, everything was warm and his stomach felt very comfortable. She didn't know that this was not because of the ginger, but because there was carbon dioxide in the cola, which could neutralize stomach acid.
Yang Fan leaned lazily on the back of his chair and chanted to Chen Xi across the long dining table:
"The southeastern shape is beautiful, the three Wu cities, Qiantang has been prosperous since ancient times. Smoked willows draw bridges, wind curtains are green, and there are hundreds of thousands of homes. Clouds and trees surround the embankment and sand, roaring waves roll frost and snow, and the sky is boundless. ... The lakes overlap Qingjia , there are three autumn osmanthus seeds and ten miles of lotus flowers. Qiang pipes clear the sky, water chestnuts sing in the night, and old lotus babies are playing and fishing.…”
"Master, are we going to Jiangnan?" Chen Xi asked happily, Jiangnan! The most beautiful place in the world.
Little beauty Chen Xi is a girl from Tianjin, born and raised in the north. But after reading so many poems describing Jiangnan, my yearning for Jiangnan has already penetrated deep into my bones.
"On this voyage, we will first go to Hangzhou, and then I will go to Suzhou to meet a friend. Then when we come back, we will set sail back to Beitangkou." Yang Fan said.
"Sir, you still have friends in Suzhou," Chen Xi said in surprise. In her impression, the master seemed to have never left the north.
"I plan to meet Zhang Pu. I have been exchanging letters with him." Yang Fan said.
"Ah, Zhang Pu, Zhang Tianru, Mr. Tianru is so famous in Jiangnan," Chen Xi's eyes were filled with little stars. Zhang Pu was very popular in the late Ming Dynasty and belonged to the top class.
"Zhang Pu has a deep background and is a complicated person. You are too young and have too little experience in world affairs. There is no benefit in contacting him. Just stay in Hangzhou and wait for my return."
"Okay." Seeing that Yang Fan had no intention of taking him to Suzhou, he was a little disappointed. However, he quickly adjusted his mood and said, "I just need to test the steam engine and transmission system. It's better to stay in Hangzhou."
