Chapter 792: Straightly hanging cloud sails to help the sea
Su Dingfang and others all had dark looks on their faces. These two old people were fooling around without restraint. How could they be so chatty?
Fang Jun felt even more cordial. This was his old subordinate. Now that he saw him unexpectedly, he felt very relieved.
Liang Renfang interjected: "General Manager, how about we raise the sails and set sail first, and you two can discuss it slowly in the helm building later?"
Fang Jun waved his hand casually and said: "You can just raise the sail. What do I have to talk to this old guy about? There is a generation gap!" After saying this, he supported Zheng Kunchang and came to the helm together.
Chat in a low voice.
Liang Renfang on the deck directed the craftsmen to take out the sails from the bilge, and it took a while to install the sails properly.
Liang Renfang tested the wind direction and found it was southeasterly.
From here, it is a tailwind when you go north along the Wusong River. When you leave Wusongkou, you turn along the river to the southeast and follow the river to the sea, you are facing a headwind.
Liang Renfang shouted: "Raise the sails and set sail!"
The huge sailing gear was raised up to the mast with ropes by craftsmen. Several sails were inflated by the wind as they were raised. The huge hull slowly slid on the water. The small sail on the bow and the jib on the stern were raised continuously.
The sails were blown by the wind, and the ship's speed became faster and faster.
The observation deck is at the stern of the ship. It is an open platform that surrounds the entire stern and is also the captain's residence. Su Dingfang and others followed Fang Jun to the observation deck. At this time, the sailboat was gradually accelerated by the wind, and the bulging sails produced
With strong thrust, the sailboat sailed quickly towards Wusongkou.
The bow of the boat broke through the river, riding the wind and waves, and the sound of wind came to my ears, as fast as a galloping horse!
Su Dingfang said excitedly: "It's really fast! With this speed, our navy will dominate the sea. If we want to fight, we will fight, and if we don't, we will avoid it. However, the enemy wants to fight but cannot catch up, and wants to run away."
If you don’t fall, from now on, you will be able to sail across the ocean and remain invincible!”
Liu Rengui lay on the edge of the observation deck, looked at the two decks below, and said, "Did you see that empty position? I heard the chief manager say that a new type of weapon that can kill enemies from a hundred feet away will be installed there in the future.
Firearms, at that time we were really invincible, the ocean was so big that we could conquer it!"
Liu Renyuan wondered: "What kind of firearm is this? It can kill an enemy from a hundred feet away? Does the imperial court allow us to put it on a battleship? You must know that during this trip south, His Majesty mentioned to the General Manager the use of the 'Zhentian Lei'
There are many concerns about the naval battle, and so far there is no decree whether to allow it or not. If there is really a firearm that can kill the enemy a hundred feet away, it will be much more powerful than the "Shattering Thunder". Your Majesty will
Do you agree?"
The imperial court's strict control over anger was almost unprecedented.
Since the death of Changsun Chong without a trace, His Majesty has placed strict restraints on the Shenji Camp. He even transferred Li Daozong, King of Rencheng City, to the capital to take charge of the Shenji Camp and stayed in the Wei Palace to take strict precautions.
Although the preparation of gunpowder was handled by another department, and no one except Fang Jun knew the secret recipe, Changsun Chong was in charge of the Shenji Battalion, the only firearms force in the empire, at the time. Who can guarantee that Changsun Chong did not obtain the gunpowder formula?
If Changsun Chong is able to prepare gunpowder, coupled with his familiarity with the palace, the consequences will be disastrous!
Among the civil and military officials of the entire dynasty, only Li Daozong, the "lone minister" of Ren City, could make His Majesty Li Er completely trust him...
Before Liu Rengui could answer, Su Dingfang had already said with a smile: "This is the responsibility of the general manager, what does it have to do with you? Now let's recall your secret method of roasting sheep and show it to everyone tonight."
Liu Renyuan was stunned when he felt that the whole ship had gradually swerved...
The wind blew the sails and produced huge thrust. After arriving at Wusongkou, the sailboat turned right, and the huge hull drew a huge arc on the river. In order to resist the strong centrifugal force, craftsmen acting as sailors drove the warship to make the ship
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 the right direction. 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 looking at the fully bulging sail for a while, and for a while looking at the bow of the boat chopping the waves.
The headwind hit, and the boat's speed slowed down significantly...
Liu Renyuan snorted twice and said displeasedly: "Didn't you brag that the water can be sailed in the wind? Mother! You know that old Heizi is lying and talking nonsense. He must let him roast ten or eight sheep at night..."
In his heart, there was no joy or joy of winning the bet, only disappointment and sadness...
If there really were warships that could sail against the wind, they would be able to completely get rid of the dependence of sea-going ships on monsoons. Since ancient times, ships sailing on the sea have relied on monsoons to achieve the purpose of long voyages.
In ancient times when there was no mechanical power, sailing ships mainly relied on changes in monsoons and ocean currents, of which monsoons were the decisive factor. "When ships go in November and December, the north wind blows; when they come in May and June, the south wind blows."
Wind." Whether you go to Nanyang or go to Goguryeo or Japan from the south of the Yangtze River, you must rely on the monsoon to provide power. If you miss the wind season, you will have to wait another year...
But if there are sea ships that can sail against the wind, they can go north and south all year round. For merchant ships, they can go back and forth between Goguryeo and Japan several times a year. The profits brought by this are almost ten times or even
An increase of dozens of times!
For naval warships, it means that they can go to sea to destroy pirates anytime and anywhere!
Liu Renyuan was extremely disappointed. He clicked his tongue and complained: "What he said seemed to be true. I almost deceived someone..."
Before he finished speaking, the ship suddenly shook!
Immediately afterwards, Liu Renyuan felt that the warship under him was running wildly like a war horse that had been severely whipped, and suddenly the speed increased to the limit!
Liu Renyuan opened his mouth wide and stared dumbfoundedly at the warship beneath him sailing forward in a strange trajectory on the wide river, drawing a zigzag, running faster and faster, running faster and faster, like a galloping horse!
Liu Renyuan said consciously: "Mother... cough, cough, cough!"
But a breath of river wind was poured into his mouth, and he almost choked and lost his breath!
Su Dingfang was also dumbfounded. He could really sail against the wind...
Liu Rengui looked excited, but Pei Xingjian had already shouted to Xi Junmai: "Go into the wind! Go into the wind! Sure enough, you can sail into the wind! Hahaha, the chief manager is a genius, he can really sail into the wind!"
Su Dingfang punched the fence hard and 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 such a sharp weapon, why worry about not being able to navigate 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 excitedly like a child: "You can really sail against the wind! Ah haha! I didn't say it, I'm so thorough
I’m convinced, I’m convinced! I’ll cook and roast the whole lamb myself tonight, I’m willing to admit defeat, haha!”
In fact, strictly speaking, this is not sailing into the wind in the true sense.
According to the principle of aerodynamics, as the fluid speed increases, the pressure will decrease. In order for the air to bypass the outwardly curved sail surface, it must speed up, so the pressure decreases, generating suction, which pulls the sail to one side. The leeward side of the sail is
The suction force generated by the reduced pressure is quite large, which can be twice as strong as the force pushing the sail on the windward side.
The suction and thrust generated by the wind on both sides of the sail make the ship move sideways; but there is a device on the bottom of the ship to prevent the ship from moving sideways. Therefore, the wind force is decomposed into two components, one component pushes the sailboat forward, and the other
The component force causes the ship to tilt to the leeward side, but such force obviously will not cause the huge hull to capsize...
To be precise, it should be sailing with crosswind.
But this is not a problem at all!
As long as the speed can be maintained or even slightly accelerated when facing the wind, it doesn't matter whether it is facing the wind or against the wind?
Liang Renfang smiled and said: "Liu Lieutenant, please don't let me offend you. Whether it is the structure of this ship or the design of the triangular sails, they are all made by the chief steward. If you want to roast a whole lamb, you should offer it to me."
Give it to the General Manager!"
Liu Renyuan laughed and said: "No problem! Tonight, I will go out of my way to be a cook, so that everyone can enjoy the taste of roasted sheep! Chief manager, you are really amazing! The speed of this ship is simply too fast.
Previously, Director Liang said that a round trip from Laizhou to Liaodong only takes seven or eight hours, so I thought he was bragging, but now it seems that it is true, and I have really learned a lot!"
Fang Jun said with a smile: "Is this exciting? This kind of ship is indeed very fast, but I value its flexibility and maneuverability more. It is very suitable for use as a warship. In terms of speed alone, there are others faster than it!
