In the power room of the steamer, a group of sailors, shirtless, skillfully shoveled the coking coal piled up next to it into the combustion furnace. Pen, fun, pavilion www. biquge。 info

In the hot summer, in this boring environment, you have to bake on the stove all the time, which can be said to be a kind of torment.

But the sailors had to endure it, because it was their duty.

The leader of the power room, while looking at the newly developed thermometer on the boiler wall, shouted loudly to the sailors below: "The temperature is not enough, add more, continue to add!" ”

The appearance of the thermometer is also due to the fact that he was deceived by Li Hongfei before, the Italian glass craftsman Hopnave.

The first thermometer was invented in 1593 by the Italian scientist Galileo.

His first thermometer was a glass tube with one end open and a walnut-sized glass bubble at the other end, which was heated first, and then inserted into the water, and with the change of temperature, the water surface in the glass tube would move up and down, and the temperature change and temperature could be determined according to the amount of movement.

This kind of thermometer is very easy to manufacture, and the main ingredient is glass, so Italian glass craftsmen basically make their own thermometers, and Hopnaf is no exception.

Since being taken to Baoshan Industrial Zone by Li Hongfei, Hopnav finally realized that he had offended someone.

In order to seek Li Hongfei's "forgiveness", Hopnauff used all his skills, from glass dyeing, to fully transparent glass, to the manufacturing process of large pieces of glass, and a series of technologies, all of which were taken out without concealment.

The reason why he came up with various glass manufacturing techniques in one go was purely because he was deceived by Li Hongfei again.

In Hopnerf's view, Li Hongfei can see the fake "Heart of the Ocean" at a glance, that must be a good knowledge of glass manufacturing technology, and after coming to Baoshan Industrial Park, Li Hongfei used the understanding of glass in later generations to teach Hopnaf a good lesson.

even once made Hopneuf think that Li Hongfei himself was a master of making glass, and with someone knowledgeable to supervise him, Hopnerf didn't bother to keep those glass-making techniques that he was proud of before.

Just when Hopnav thought that it would be difficult for him to turn over, by chance, the researchers under Song Yingxing inadvertently mentioned the experiment of thermometers when they asked him to customize a special type of glass.

This is a rare opportunity for Hopnave: you have talents in glass manufacturing, but no one can get a thermometer yet!

Making a thermometer was a piece of cake for Hopnave, and he soon volunteered to participate in the thermometer research program.

Song Yingxing's thermometer research plan, because of the joining of Hopnave, finally became faster, and the research team improved the Galileo thermometer, and finally produced a new generation of thermometers that use mercury as a temperature measuring substance.

At the same time, Hopnauff was officially accepted by Li Hongfei, and at the same time hired as a "guest professor" of Suzhou Heavy Industry, except for the absence of imperial court official titles, all treatment is basically the same as that of professor-level personnel.

Well, the topic is off the hook, and now we move on to the boiler room on the ship...........

"Alright, stop adding coal." Seeing that the thermometer had reached the warning line, the team leader hurriedly asked the sailors below to stop coaling, and then pulled the safety valve while saying to the inspectors next to him: "The boiler temperature has reached the highest value, you can make statistics, and the speed at this time is the fastest speed of the ship without sails." ”

The steamer had been sailing for a full hour, and the statistics of the sailless state were already in: the cruising speed was 4 knots, and the maximum speed was 6 knots.

Such a speed is already the limit of all sailing warships at present.

After all, the sail warship mainly relies on God to give face, the stronger the wind, the faster the speed of sailing, the wind is small, or it is against the wind, the speed is basically negligible.

However, not even the existing sail warship, even the fastest record, could surpass this experimental steam-engine warship.

After all, with the help of the wind, there are also skills, if you use the typhoon, then let alone speed up the sailing, the passage of the wind can directly blow the warship overturned.

"Hang the sails and calculate the sail speed." After listening to the speed of steam power, Li Hongfei began to let people test the maximum speed of sailing at full speed.

"Set sail!"

With a loud shout, the sailors on deck began to pull up the sails.

"Detect the wind direction, level 2 southeast wind!"

"The mainmast is fifteen degrees to the left!"

"Left rudder, forty-five degrees!"

“..............”

As the sails were raised, the sailors on deck began to get busy.

The steam engine cooperated with the sails, and the speed soared again, and in the past, it took about two hours to reach the wharf in Shanghai County by boat down the river at the earliest.

Now, just over an hour, the steam warships can already see the goods on the docks of Shanghai County, as well as all kinds of merchant ships, large and small.

"Look, is that ship on fire?" Someone on the pier looked at the "smoking" steamer and shouted.

"Huh? It seems that it is still a warship, and there are artillery on it, so it can't be Lord Li's fleet that has been attacked! "There are also people who are more imaginative.

"No, the ship is fast, a lot faster than the clippers." There are people who know how to find the fundamental problem.

"It's all burning your ass, can you not run faster!" There are honest peasants, whose brains have not turned for a while, and they follow blindly mingling.

“...............”

In short, the warship that sailed out of Baoshan Town quickly attracted the attention of everyone on the dock.

Situ Yan happened to be checking the accounts on this dock today, and she also found this warship with unusual movements.

"Send a small boat over and see what's going on." Situ Yan sent people to investigate.

If there is really a battle upstream, then it is necessary for the Cao Gang to impose martial law, after all, all the warships have sailed to Shanghai County, and it is still necessary to take precautions in advance.

However, how can the merchant ships of the Cao Gang catch up with the steamers, the two are not of the same level at all, and in the end, the people of the Cao Gang can only ask what happened to the warship through the flag.

"The flag replied, and it was said that the new warship developed by Suzhou was undergoing a speed test, so they didn't have to panic." After Li Hongfei saw the other party's flag, he ordered the herald on the side.

This incident is also to blame Li Hongfei for not making arrangements in place, only thinking about sending warships to escort the ship, but he didn't expect that those warships couldn't catch up with the steamer at all, and at the same time, because of poor consideration, he failed to notify Shanghai County in advance, which caused such a big sensation.
