Tiantang Splendid

Chapter 791

Su Dingfang and the others all had black lines on their faces. These two people are always talking nonsense, how can there be such chatter?
Fang Jun, however, felt very cordial, this was his old subordinate, seeing him unexpectedly now, he was very relieved.

Liang Renfang interjected: "Chairman, why don't we set sail first, and the two of you will talk in detail later in the cockpit?"

Fang Jun waved his hand casually and said, "You just hoist the sails. What can Benhou and this old guy have to talk about? There is a generation gap!" He said so, but he helped Zheng Kunchang and came to the cockpit together. Start talking in a low voice.

Liang Renfang on the deck directed the craftsmen to take out the sails at the bottom of the bilge, and it took a long time to install the sails properly.

Liang Renfang tried the wind direction, and it was southeast.

From this, going north along the Wusong River is a downwind, and when you leave the Wusongkou, turn along the river and go southeast along the river to the sea, it is just against the wind.

Liang Renfang shouted loudly: "Raise the sails, set sail!"

The huge sails were hoisted up to the mast by the craftsmen with ropes, and the sails were filled with the wind as they were raised, and the huge hull slowly slid on the water.The small sail at the bow and the triangular sail at the stern are raised continuously, the sails are blown by the wind, and the speed of the ship is getting faster and faster.

At the stern is the lookout, a kind of open platform that goes around the entire stern and is the captain's quarters.Su Dingfang and others followed Fang Jun to the observation deck. At this time, the sailboat was blown by the wind and gradually accelerated. The bulging sails produced a strong thrust, and the sailboat quickly sailed towards Wusongkou.

The bow of the boat breaks through the river, rides the wind and waves, and the sound of the wind is heard in the ear, as fast as a galloping horse!
Su Dingfang excitedly said: "It's really fast! With this speed, the sea is full of our sailors. If we want to fight, we will fight. If we don't fight, we will avoid it. If you don’t lose it, from now on, you will be able to cross the ocean and remain invincible!”

Liu Rengui lay on the edge of the watchtower, looked at the two decks below, and said, "See that empty space? I heard from the chief executive that a new type of weapon that can kill enemies from a hundred feet away will be installed there in the future." Firearms, then it is really invincible, the ocean is so big, we can do whatever we want!"

Liu Renyuan wondered: "What kind of firearm is this? It can kill the enemy from hundreds of feet away? Will the imperial court allow us to put it on the battleship? You must know that this time he went south, His Majesty proposed to the General Manager to use the 'shocking thunder' I have a lot of concerns about the sea battle, and so far there is no decree whether to allow it or not. If there is a firearm that kills the enemy hundreds of feet away, it is much more powerful than the "shocking thunder". Your Majesty will agree?"

The imperial court's strict control over anger has almost reached an unprecedented level.

Ever since Changsun Chong died without a trace, His Majesty has imposed strict restrictions on the Shenji camp, and even transferred Rencheng King Li Daozong to Beijing to take charge of the Shenji camp.

Although the preparation of the gunpowder was in charge of another department, the secret recipe was known to no one except Fang Jun, but Chang Sun Chong was in charge of the Shenji Battalion, the only firearms unit in the empire at that time. Who can guarantee that Chang Sun Chong didn't get the gunpowder formula?
If Changsun Chong is able to prepare gunpowder, coupled with his familiarity with the forbidden palace, the consequences will be disastrous!

In the civil and military affairs of the Manchu Dynasty, only the "lonely minister" Li Daozong, the king of Rencheng, can completely trust His Majesty Li Er...

Before Liu Rengui could answer, Su Dingfang had already smiled and said, "This is the responsibility of the chief executive, what does it have to do with you? Now, let's recall your secret method of roasting sheep in Diao Yin, and show everyone a good hand tonight."

Liu Renyuan was stunned, only to feel that the whole ship had gradually turned sideways...

The wind blows the sails and produces a huge thrust. After reaching Wusongkou, the sailboat turns right. The huge hull draws a huge arc on the river. The upper part of the body poured sharply inward, leaving a white arc-shaped water mark behind the stern.

After a quick turn, the hull slowly returned to normal. At this time, it still entered the Yangtze River waterway, and its course turned to the southeast, which happened to be against the wind.

Liu Renyuan became slightly nervous, his eyes looked at the bulging sail for a while, and the bow of the boat for a while.

When the wind hit, the speed of the ship slowed down significantly...

Liu Renyuan snorted twice, and said in displeasure, "Didn't you brag that the surface of the water can sail against the wind? Mother! I know that old Heizi is talking nonsense, and he must let him roast ten or eight sheep at night..."

In his heart, there is no joy or joy of winning the bet, only disappointment and regret...

If there really is a warship that can sail against the wind, it can completely get rid of the dependence of seagoing ships on the monsoon.Since ancient times, ships sailing at sea have relied on monsoons to achieve long-distance voyages.

In ancient times when there was no mechanical power, sailing ships mainly relied on changes in monsoons and ocean currents, among which monsoons were the decisive factor. "The ship goes in November and December, and the north wind blows; when it comes in May and June, the south wind blows." Whether it goes to Nanyang or sails from the south of the Yangtze River to Goguryeo and Wa, it must rely on the monsoon to provide power.If you miss the wind season, you can only wait another year...

But if there is a sea-going ship that can sail against the wind, it can travel from south to north all year round. For merchant ships, it is equivalent to going back and forth between Goguryeo and Wa several times a year, and the profits brought by it are almost ten times or even Dozens of times the increase!

And for naval warships, it means that they can go to sea to destroy pirates anytime, anywhere!
Liu Renyuan was extremely disappointed in his heart, tsk tsk, and complained: "It's as if it's true, I almost deceived someone..."

Before the words fell, the hull suddenly shook!
Immediately afterwards, Liu Renyuan felt that the warship under him galloped like a warhorse that had been severely whipped, and suddenly increased its speed to the limit!
Liu Renyuan opened his mouth wide, and stared dumbfounded at the warship below him sailing forward on the broad river with a zigzag in a strange trajectory, running faster and faster, like a galloping horse!
Liu Renyuan said consciously: "Mother... cough cough cough!"

But he was poured into his mouth by a mouthful of river wind, and almost choked to death!

Su Dingfang was also dumbfounded, he could really sail against the wind...

Liu Rengui looked excited, but Pei Xingjian had already bought with Mr. Xi and shouted: "Facing the wind! Facing the wind! Sure enough, he can sail against the wind! Hahaha, the chief executive is a genius, he can really sail against the wind!"

Su Dingfang slammed his fist on the fence, let out a long breath, the river wind blew in his face, his face was refreshed, his clothes were fierce, and his spirit was high!

With this sharp weapon, why not be able to cross the seven seas?
Liu Renyuan had already dived into the cabin under the observation deck, grabbed Liang Renfang who was talking to Fang Jun, and shouted like a child in excitement: "I can really sail against the wind! Haha! I didn't say anything, a certain Convinced, convinced! Tonight I will personally cook the whole lamb, and I am willing to accept the bet, haha!"

In fact, strictly speaking, this is not really windward sailing.

According to the principles of aerodynamics, as the fluid velocity increases, the pressure decreases.The air has to pick up speed to get around the outwardly curving sail, so the pressure decreases, creating suction that pulls the sail sideways.The suction produced by the reduced pressure on the leeward side of the sail is quite strong, twice as strong as the force that pushes the sail on the windward side.

The suction and thrust produced by the wind on both sides of the sail make the ship move sideways; but the bottom of the ship prevents the ship from moving sideways, so the wind force is decomposed into two components, one pushes the sailboat forward, and the other pushes the sailboat forward. The component force causes the ship to tilt to the leeward side, but such a force obviously won't cause the huge hull to capsize...

To be precise, it should be crosswind sailing.

But that's not a problem at all!
As long as he can maintain the speed or even speed up slightly when facing the wind, it doesn't matter whether he is facing the wind or against the wind?

Liang Renfang said with a smile: "Lieutenant Liu, don't worry about it. Whether it's the structure of the ship or the design of the triangular sails, they are all from the hands of the chief steward. If you want to cook a whole lamb, you should sacrifice it." Give it to the chief executive!"

Liu Renyuan laughed loudly and said: "No problem! I'm going to go all out tonight, and I'll be a cook for a while, so that everyone will always taste the taste of roasting sheep! Chief Manager, you are really amazing! The speed of this boat is simply too fast. Earlier, Mr. Liang said that the round trip from Laizhou to Liaodong was only seven or eight hours, so I thought he was bragging, but now it seems that it is true, it really made me gain insight!"

Fang Jun smiled and said: "Is this exciting? This kind of ship is really fast, but Benhou pays more attention to its flexibility and maneuverability, which is very suitable as a warship. If you only talk about speed, there are other faster than it! "
