Chapter 261 Preparing for the Ocean
Xiao Qi heard that Zhang Dali changed his name and called him "Marshal", so this guy already knew that he was wrong.
This group of old subordinates of the Changsheng Camp, in order to appear close to each other, usually call themselves son-in-law. When they need to treat them seriously or give orders by themselves, they will become serious and call themselves Marshal.
After waving his hands, Xiao Qi continued:
"This battleship is the first steam-powered warship built by Da Song, you must remember that your task now is not to drive it to fight as soon as possible.
Instead, get acquainted with its advantages during the exercise, find out its shortcomings and report them to me, so that we can build better warships in Song Dynasty.
When we have better and safer warships, not only will we be able to kill the enemy sharply, but we will also be able to better protect the safety of our sailors and generals of the Changsheng Battalion. "
Zhang Dali hastened to salute: "I would like to follow the Commander-in-Chief's instruction, and I will eventually understand."
"Okay, let's order the ship to sail. I want to take a closer look at what this warship looks like when it is driven."
Zhang Dali hurriedly sent an order to lift the anchor and sail the boat.
As the fire of the 'Longwei' steam engine gradually increased, this huge ship slowly left the port and headed for the open sea.
The 'Longwei' was getting faster and faster, and Zhang Dali kept smiling.
In his opinion, such a warship that can run fast on the sea without manpower paddling or sails is simply a magic weapon.
But Xiao Qi's brows were condensed into knots.
Because he found that standing in the cab far away from the power transmission system, he could feel the vibration!
This is not a good thing, not to mention that this battleship is made of wood. Although there are steel plates on the outside, it is only wrapped around the outside of the ship.
Even a warship built with an overall steel structure, in such a violently shaking environment for a long time, the lifespan of the warship will be greatly reduced, and if it is not done well, it will suddenly disintegrate when it is driving on the sea.
After discovering something was wrong, Xiao Qi walked out of the cab and walked towards the cabin of the steam boiler and transmission system at the back.
Zhang Dali didn't know what Xiao Qi was going to do, and he, the captain, didn't dare to leave the pilothouse. After all, he had just taken over this battleship, and he hadn't figured it out yet, let alone hand it over to his deputy.
I could only watch helplessly as Xiao Qi and several soldiers left the cab and walked towards the power cabin at the back.
Xiao Qi came to the power cabin and checked the transmission system all the way to the stern, only then did he understand why the ship was shaking so badly.
It turned out to be the power transmission system. After driving the transmission shaft to rotate, when the transmission shaft transmits power to the rear paddles, it is because of the resistance from the paddles and the force from the power transmission system.
The transmission shaft vibrates very badly under the action of two opposite forces. Of course, the perfect transmission system now enables the transmission shaft to completely resist these two opposite forces.
But this unavoidable tremor made Xiao Qi's heart ring loudly.
This problem must be solved, otherwise this wooden warship will definitely disintegrate suddenly one day!
Because the transmission shaft brought too much tremor to the warship, this tremor would definitely make the warship, which could have a lifespan of ten years, die after one year of use.
Xiao Qi immediately told the soldiers in charge of the power system to reduce the power. In fact, he asked the boiler burners to turn down the work and release more steam to slow down the speed.
As the speed slowly decreased, Xiao Qi found that when the power output was low to a certain level, the vibration of the transmission shaft suddenly became much more stable.
Xiao Qi immediately ordered the officer in charge of the power system to write down this power output value. As long as it is not in war or encounters severe sea conditions, the power output must not be higher than this peak value.
The officer hurriedly wrote down the power value, and also wrote down Xiao Qi's order.
After figuring out what caused the warship to tremble, Xiao Qi returned to the wheelhouse.
Zhang Dali clearly felt that the speed of the ship had slowed down in the bridge, and he didn't give the order, so it must be his commander who ran to the engine room to give the order.
Seeing Xiao Qi coming back, he quickly asked: "Commander, is there something wrong with the power system at the back?"
Xiao Qi nodded and told Zhang Dali that as long as there are no bad sea conditions or engaging with enemy ships, it is fine to keep this speed.
The previous situation that made the whole ship feel tremors should not happen often, as that situation will greatly reduce the lifespan of the warship.
Zhang Dali was in a cold sweat when he heard that, since this guy took over this new type of warship, every time he went to sea, he ordered to burn the boiler to the maximum and run at the highest speed.
Otherwise, the warship had just left the pier, how could the soldiers in the power cabin burn up the fire so vigorously? It was because the soldiers knew that the captain likes racing boats.
Zhang Dali hurriedly took out his own sailing rules and added this one.
Seeing him being so serious, Xiao Qi was very satisfied, and comforted him:
"During normal drills, it is enough not to let the hull tremble, and it is not a big problem in severe weather or occasional tremors during wartime.
Remember not to have that kind of situation happen again, otherwise after a long time, maybe one day the boat will make a big hole. "
Zhang Dali hurriedly saluted and accepted the order, vowing in his heart that he would never be so frightening in the future, he was really ignorant and fearless before!
After a long circle on the sea on the 'Longwei', Xiao Qi disembarked and returned to Lin'an, the capital city.
The vibration of the transmission shaft became another problem that troubled Xiao Qi, which made him feel very aggrieved.
When I originally designed the propulsion system of a steamship, I couldn't make an underwater propeller because of my current technical capabilities, so I had to choose a propeller that was half underwater and half on the water.
Fortunately, even the wheels and paddles made the transmission shaft vibrate badly.
Although the tremor is much reduced when the speed is reduced, but that speed is no longer a battleship, but has become the speed of a civilian transport ship.
Just when Xiao Qi locked himself in the study and worried.
"Ding! The host triggers a specific task."
"This specific check-in task is: to eliminate the tremors of the 'Longwei' warship when it travels normally at high speed."
"The requirements for completing the task are: to eliminate the tremors produced by the "Longwei" warship when it is running at high speed normally,
"This task is a specific reward task. Reward after completing the task: propeller manufacturing method and underwater transmission system waterproof structure blueprint."
"This task is a specific task. After completion, there are only rewards, and there is no sign-in and upgrade experience."
"The specific check-in task is an additional check-in task, and the system will always default that the host agrees to accept it. The duration of this task is one year."
"Ding, if this task fails, the host will not be able to get the opportunity to unlock the propeller manufacturing method and the structural blueprint of the waterproof transmission system again within ten years."
Hearing the specific tasks released by the system, Xiao Qi's eyes were almost brightened with excitement. The manufacturing method of the propeller and the structural drawings of the underwater waterproof transmission system must be obtained as soon as possible.
In the following days, Xiao Qi either stayed in the study to write and draw, or went to the Song Dynasty Foundry Bureau to discuss with those senior craftsmen how to reduce the vibration of the transmission system.
In order to find an effective solution to the problem as soon as possible, Xiao Qi also specially found a warehouse in the foundry bureau, and got a set of steam engine and transmission system.
Every time I have a new idea with these senior craftsmen, I will test it on this set of machines.
The old saying is true, three cobblers can beat one Zhuge Liang, not to mention so many senior craftsmen in the foundry bureau trying to find a way together.
After more than two months of research and many failed experiments, Xiao Qi finally thought of a way.
This method is actually simple, that is, after many experiments, Xiao Qi found that although the transmission shaft is very thick, but because the length is too long, when the transmission shaft rotates, it will vibrate to a certain extent.
Coupled with the resistance at the end of the drive shaft, the magnitude of the tremor is increased.
Xiao Qi asked people to make many large bearings with the same inner diameter as the drive shaft according to the size of the drive shaft, and also asked the rubber workshop to make very thick and huge rubber pads.
It took him two days to design a tripod steel frame with fixed bearings according to the height of the drive shaft of the 'Longwei' and the hull deck.
After the things were finished, Xiao Qi and those senior craftsmen did many experiments on the steam engine and power transmission system used for the experiment.
In the end, I was surprised to find that this method turned out to be surprisingly good.
It not only reduces the vibration of the drive shaft by [-] to [-]%, but also makes the power transmission of the drive shaft smoother.
Xiao Qi was overjoyed, and immediately took these bearings and the supporting triangular steel frame, rushed to Shanghai Port, and installed these things on the drive shaft of the 'Longwei'.
After many tests in the Foundry Bureau, the effect of installing two such devices on the transmission shaft of the battleship 'Longwei' is the best.
Xiao Qi installed one such device at the positions of one-third and two-thirds of the length of the drive shaft respectively.
Driving the 'Longwei' out to sea again, Xiao Qi found that the warship would vibrate violently only when its speed was more than twice its original speed.
And the magnitude of the vibration is much smaller than the last time I discovered the problem.
Originally, there were two more position bearings and tripod supports on the transmission shaft, which greatly reduced the vibration of the transmission shaft.
After the ship is fully powered, the inevitable vibration of the drive shaft is fixed by the thick rubber pad between the tripod and the hull, which eliminates more than half.
This makes the 'Longwei' even if it increases its speed to twice its previous speed, the vibration amplitude of the ship's hull is still much smaller than when the problem was discovered last time.
Just when Xiao Qi wanted to give an order to continue to increase the firepower of the steam boiler to see the current limit of the ship.
"Ding! This specific check-in task: Eliminate the tremors of the warship 'Longwei' when it is running at normal high speed has been completed."
"Ding! Rewards after the completion of this specific task: the propeller manufacturing method and the waterproof structure drawings of the underwater transmission system have been issued."
"This task is a specific task. After completion, there are only rewards, and there is no sign-in and upgrade experience."
"Ding! This specific mission has been completed, and the next specific mission needs to be triggered by the host."
Hearing the system notification that the task was completed, a big stone in Xiao Qi's heart finally fell to the ground.
He no longer wanted to test the limit of this warship at sea, so he immediately ordered the warship to return to the port, and told Zhang Dali to let him slowly test the limit of this ship in the future and record it.
As soon as the "Longwei" docked, Xiao Qi led his soldiers and hurried back to Lin'an, the capital.
You can't blame Xiao Qi for being so anxious. The manufacturing method of the propeller and the underwater transmission waterproof system are too important to him.
In his previous life, he had accidentally read an article about propellers. Even in the early twentieth century, only a few countries could produce good ones.
Although the ones made by most countries can be used, there are not small errors in the specific gravity of the blades of those propellers, which often causes problems in the power system of the ship.
The report he read mainly talked about submarine propellers. Submarine propellers need to be more precise. Even if the specific gravity of the blades is slightly larger, the noise of the submarine will be much louder.
Of course, Xiao Qi didn't want to build the precision propellers used in submarines. Even ordinary propellers, Xiao Qi was worried that with the current technical capabilities, it would be impossible to build them.
But Xiao Qi is not too worried. Now that he has a basic industrial machine tool, he can't make it now. Soon, various machines derived from industrial machine tools will appear.
Things like propellers, which are precision machining in this era, will soon be successfully manufactured.
Now he has to study carefully, the blueprints of these two things given by the system, even if the current technical ability can't make it, he must know which aspect of technical ability needs to be improved.
The reason why Xiao Qi is so anxious is also because he has always wanted to lead the fleet and go to the west to ask those guys to come down from the tree.
He used to think about waiting for the first railway to be built before going there.
But with the completion of the "Longwei", Xiao Qi's obsession with sailing freely to the west, which he had suppressed deep down in his heart, became increasingly restless.
This made him feel bad about eating recently, and he always had the idea of starting an army and marching westward from time to time.
Xiao Qi had already made a plan in his mind, that is, he would only lead the navy to do things by water.
As for the land route, let's keep it for the Mongols. It is always very enjoyable to see the whip of God beating those things that have just learned to walk upright with their own eyes.
As for whether Da Song would be threatened, Xiao Qi never thought about it at all, if now he led the Changsheng Battalion to fight everywhere.
It doesn't take ten years, all the surrounding countries will be drawn into the territory of the Song Dynasty, and even Mongolia will be included.
However, Xiao Qi does not intend to do this. In the words of his previous life, his ideal is the stars and the sea.
The big island in the depths of the ocean and the vast land on the half of the earth under his feet are what Xiao Qi wants most.
As for the Asian side, let them fight. As long as you don't provoke Da Song, don't talk to them. Sooner or later, the territory here will belong to Da Song, so don't worry.
