The principle of the early steam turbine can be understood as a multi-bladed windmill, a bunch of steam-spraying nozzles are gathered in a circle to blow against the fan blades of the windmill, and then the blades rotate with the shaft of the windmill, so that the original reciprocating motion with the piston in the steam pushing cylinder becomes a direct drive to the shaft of the steam turbine to rotate.

The steam turbine is composed of a thick steel disc in the center and the outer edge of the steel disc arc-shaped blades, when the steam is sprayed onto the blades, the turbine rotates, and the greater the steam velocity, the faster the turbine rotates, and the machine that uses steam to make the impeller rotate is called "steam turbine".

In 1882, Laval in Switzerland built the first single-stage impulse steam turbine, which was a steam turbine with only one row of nozzles and one row of blades, and several single-stage steam turbines were connected in series to form a multi-stage steam turbine.

As the pressure of the steam gradually decreases as it passes through the stages, the volume becomes larger, and the flow area of the steam turbine gradually increases in order for the steam to flow through the blades, resulting in an increase in the height of the nozzle and blades and the diameter of the shaft.

The power of the multi-stage steam turbine is the sum of the power of all stages, so the power of the multi-stage steam turbine can be very large according to the demand.

Compared with the steam engine, the steam turbine has light weight and small size at the same power, and does not need machinery such as cranks and flywheels to change the movement to rotation, so the rotation is uniform, there is no vibration, and the rotation speed can reach 3000 revolutions per minute.

Of course, steam turbines also have disadvantages, that is, they can only rotate in one direction, cannot be reversed, and must be used with high-pressure boilers, so they are basically used in power plants and giant ships.

In 1884, the first 10 hp (35 kW) single-stage reactionary steam turbine was built in England. In the same year, he built the first multi-stage reactionary steam turbine, which was the leading in power and efficiency at the time.

In 1897, the Turbonia was unveiled at Queen Victoria's viewing ceremony, and it made the whole world vibrate with an unprecedented speed of 5 knots, and Charles Parsons proved to the world that the steam turbine could challenge the traditional steam engine to become the new power of ships.

It is impossible for Ferdinand not to know such a big thing, and at the same time, the thermal power plant that supplied Vienna's electricity also uses steam turbines to generate electricity, although he does not understand the working principle of steam turbines, but he is not alone.

"Know a little, steam turbines are no secret." If Gao Hongsheng is talking about this thing, it is really .......

"Where's the oil-fired boiler?"

"Oil-fired boilers?"

"Diesel?"

"Rangefinder?"

"Central fire console?"

"Triple turret?

"Radio telecommunications?"

“…………”

"You always know the phone, right?"

"Hmmm! I know that. After listening to a bunch of new terms stupidly, Ferdinand finally had one of them that he knew how to say quickly.

"Can you imagine what it would be like if you put all these new technologies together on a new type of warship?"

"This ,............。" Ferdinand couldn't answer Gao Hongsheng, many of these new things he had never even heard of, let alone gathered them on a single battleship.

"Ferdinand, these technologies will gradually appear in front of you in the near future, do you say that we cannot use these new technologies to build warships now? After these new technologies are applied to warships, they will change the current way of naval warfare, a new way of naval warfare will be presented in front of us, and your warships will all be wasted. ”

"Gao, do you have the technology?"

"Yes, I have the theoretical aspects, the models, and the manufacturing materials, etc., but if we want to turn them all into real things, we need a lot of people to produce them, can you provide that many people? They also have to be loyal and keep secrets. ”

"No problem, how many people do you need?"

"You have as much as you want, but you have to be able to keep it a secret."

"Okay, high. I'll solve the problem of personnel, and I'm really looking forward to the scenario you said about the application of these new technologies on a warship, well! High, if you use your new technology, what are the performance of the new warship? ”

"Don't think about it, let's come step by step, you can help talk to the emir first, it's the emir of Skoda, let him take those engineers to help us get the triple knapsack gun, you wait a minute, I'll show you the model and information of that thing."

After Gao Hongsheng finished speaking, he made a gesture to Ferdinand, then got up and went to another room, took out a model and data of the triple knapsack gun from the crossing artifact, put it in a small suitcase, thought about it and found out the information and model of the steam gas torpedo and put it in the small suitcase, and then walked back to Ferdinand's side and handed him the heavy small suitcase.

Ferdinand took the small suitcase, and before he could open it, he heard Gao Hongsheng say: "There are two things in this that we need to get out in advance, and it is relatively simple, especially this torpedo, its diameter is 533 mm, its weight is 1850 kg, the speed is 3900 meters at 50 knots, and the range is 8000 meters at 5 knots, and the charge is 380 kg. Rest assured, it's not one of those things you've ever seen spinning around in the sea, it will shoot at its target in a straight course and send enemies to the bottom with a thud. Gao Hongsheng made an exaggerated explosive gesture and said with a smile.

"Eight thousand meters, are you sure?" Ferdinand's hand that wanted to open the small leather case stopped, raised his head and asked with some suspicion.

"Sure, it shouldn't be wrong, according to your current processing capacity, it should be fine, but if it doesn't work, we can enlarge the size of the torpedo, the diameter is enlarged to 600 mm, 650 mm is not bad, I think this should be enough." After Gao Hongsheng finished speaking, he made a half-hugging movement with his hand nonchalantly.

At that time, there was no limit to the size of torpedoes, and you could build as big as you wanted, until the Washington Navy Regulations in 1921 not only stipulated the total tonnage of warships built by various countries, but also made the diameter of torpedoes mandatory, requiring that the maximum diameter of torpedoes manufactured by various countries should not exceed 21 inches, that is, 533 mm.

This is also the main reason why most of the torpedoes we saw during World War II were of this caliber, and later the habit became natural, the most important thing is that the army's weapons are very extensive, especially the caliber of ammunition, once finalized, as long as there is no fundamental change, it will basically remain the same, just like our country's 62 mm caliber rifle cartridge has advanced to 8 mm, it is difficult to change, and the sacrifice is also very large.

However, now Gao Hongsheng has no such concerns, it does not have an industrial system, but only borrows the industrial system of the Austro-Hungarian Empire to produce some weapons that can be used in this era, and as for the future, after he builds his own independent industrial system, he will seriously consider the caliber of various weapons.

"Six hundred and fifty millimeters? That's a big guy. Ferdinand placed the small suitcase on the table, and followed with his arms open and made a half-hugging motion with his two hands, with an incredulous expression on his face.

At that time, most of the torpedoes were fourteen inches, fifteen inches, but 21 inches was really a big guy, and it is no wonder that Ferdinand looked incredible.
