Chapter 398 The first whistle that broke the era!
Not long after Su Yu's carrier pigeons were sent out, Lao Zhao brought Wang Ben, Li Si, Meng Yi and others into Su Yu's courtyard.
"Su Yu, what's the matter again?" Lao Zhao asked straight to the point as soon as he came.
"Hey? Daniel is also there? 39
Daniel nodded slightly and bowed to everyone.
"I came here today to show you a good thing about the development of Daqin! Su Yu pointed to the steam-steam engine in the courtyard, which was covered with a black cloth.
"Oh? Then I'll take a good look!"
As soon as Lao Zhao heard Su Yu's words, he couldn't help but take a few more glances at the huge object covered with black cloth in the center of the courtyard.
Since it can be regarded by Su Yu as something that can influence the development of Daqin, this thing must be extraordinary!
The chatter of the other people gradually ceased, and they all waited for Su Yu to introduce this object "related to the development of Daqin".
Su Yu didn't ink, got up and went straight to the steam engine, and lifted the black cloth covering it.
Immediately, a "metal behemoth" with a whole body made of steel, with various complex devices connected to it, and a huge iron wheel appeared in front of everyone.
"Hey...this is..."
Looking at the rather complicated Tie Tuo Tuo in front of them, everyone was a little confused.
Su Yu didn't explain directly, but gave the servants a look.
After receiving Su Yu's instructions, a group of domestic servants got busy following the way Su Yu and Daniel had just handed them over.
Some lift the bucket and start adding water to the boiler, some start adding coal to ignite...
Lao Zhao and the others were looking at the clouds and fog.
They are all very curious about what Su Yu and Daniel are doing.
However, seeing that the two did not directly explain their plans, everyone did not ask any questions.
Just quietly watching the domestic servants operate.
This steam engine made by Daniel is extremely efficient.
In a short time, a pipe made of glass and a pressure gauge made of it showed that the water in the boiler had boiled and the pressure inside the boiler had reached the standard.
The next thing, it's up to Daniel to do it himself.
Daniel grabbed the handle and pulled it hard.
"Click!" After a crisp sound, Daniel took two steps back and signaled everyone to get ready.
Just when Lao Zhao and the others were at a loss...
"Woooo..."
Slitting through the sky, the whistle that should have appeared in the distant future suddenly came from the steam engine.
This sudden sound startled Lao Zhao and the others.
And Su Yu was getting goosebumps with excitement.
Among the few people present, I am afraid no one knows better than him.
What does this loud whistle sound represent?
With the appearance of the whistle, the piston inside the boiler, which was pushed open by the air pressure, began to run continuously, faster and faster.
The piston is connected with the transmission device, which transmits this powerful kinetic energy to the planetary gear, and is efficiently transmitted by the planetary gear to the transmission rod at the other end.
Finally, the metal runner on the steam engine began to rotate at a high speed and with great power.
"Woooo..."
"Rumble rumble..."
The loud whistle and the roar caused by the friction of the operation of the gear set of the transmission rod rang together.
The faces of Daniel and Su Yu were full of pride.
This is the first steam engine successfully operated by Daqin!
Looking at the "Tie Tuo Tuo" Lao Zhao and the others who were constantly operating in front of them, their faces were still blank.
what is this?
What can you do?
How to promote the development of Daqin?
Three consecutive question marks appeared in everyone's mind.
Seeing the doubts written on everyone's faces, Su Yu couldn't help shaking his head and smiling bitterly.
It seems that Daqin people's understanding and cognition of technology, and even the awareness of its application, are still at the initial level.
Even if the steam engine is here now, if there is no guidance and guidance from him.
I'm afraid that the steam engine that eventually drove the world forward will be thrown into the warehouse and eaten by them as useless things.
At most, it is occasionally novel, add water to him, fill it with coal, let him go for a spin, amuse everyone,
Few people can imagine how much this rotating force can do!
With a sigh, Su Yu shouldered the burden of paving the way for Daqin's future, and began to explain the principles and functions of the steam engine to everyone.
"What! You said that this thing can also drive ships, and it ignores the direction of the wind, and its sailing speed is several times that of the Daqin building ship!?"
Lao Zhao and the others were dumbfounded.
How could this steam engine have such endurance?
Su Yu smiled and nodded.
He said nothing about the speed of steam-powered ships.
… … 0
Where is this going?
When the ship with steam turbine as power output appears in the back, the speed of running will be called a fast.
In fact, the steam engine has only been used as a power for ships in the history of only a hundred years.
It was later replaced by high-power steam turbines.
Logically speaking, because of the appearance of Su Yu, this time should be shortened rapidly, and there is not even a time gap.
After all, the principle of the steam turbine is not far from the fundamental difference with the steam engine.
Su Yu also considered this issue, but he rejected it completely: further development, using the steam turbine as the power source of the ship, it is an attractive idea to take shape in one step.
High-power and even ultra-high-power steam turbines require a certain degree of support from the precision industry chain.
.0
Without the appearance of Su Yu, in the era of the advent of the steam engine, the world's metallurgy, forging and other industries have flourished.
Seiko manufacturing has progressed to a certain extent.
Therefore, the steam turbine can take the place of the steam engine in such a short period of time.
However, for the current level of technology and productivity in Daqin, precision manufacturing is undoubtedly more difficult.
Not to mention Seiko.
Even the normal output is still half a year ago when Su Yu came up with the popularization of the steelmaking method, which has just been solved.
Otherwise, Daqin doesn't even have enough steel, how can he still have the spare time to do Seiko?
Moreover, Seiko manufacturing requires the simultaneous follow-up of various industrial chains in order to reach the standard.
Instead of developing metal smelting alone, or forging can be achieved.
It also requires a lot of experienced workers, high hardness and precision tools, molds, and a lot of other things
At the current level of Daqin, it may take more than ten years to fully reach the standard of being able to manufacture high-power steam turbines, even with the help of Su Yu.
Although this time is indeed faster than the previous life, I don't know how much.
But for more than ten years, the steam engine alone was enough for Da Qin to conquer all the oceans in the world.
So no need to wait.
ps: During the First World War, the general civilian steam-powered ships had a speed of 12-15 knots, that is, more than 20 kilometers per hour.
The more advanced sailboats in ancient times, 3-6 knots and .
