Halfway through, Lee Hayden wanted to take a trip to Persia, after all, it is possible to become a potential important customer.

The Russians seized millions of square kilometers of land from the Persians through three wars, but did not realize their intention - to obtain a permanent temperate estuary. The British tried their best to stop the Russians, even in person. They knew very well how great trouble it would cause to its maritime hegemony if they were allowed to run to the sea.

Persia in this era has been completely divided by Britain and Russia. According to the agreement, the Russians controlled the north, while the British controlled the southern part of Persia. The game between Britain and Russia made this declining empire lucky to be preserved.

Captain Hanser promptly dissuaded Li Haidn's unrealistic idea. The security of the Kaga Dynasty could no longer be described as bad. It is said that even in Tehran, no one dared to take to the streets easily at night.

But this is not the main reason. According to legend, King Nasserding married about two thousand wives, but could not afford to arm his army. Even his expenses had to borrow money from the British and Russians to make ends meet. On the other hand, the British had almost obtained prospecting rights in the entire South Persia, and it was not easy to buy them from the British. King Nasserding could not make any decision.

Lee Haydn obviously felt a little disappointed, but there was nothing he could do.

After leaving the Gulf of Aden, the warship continued to sail towards Malacca.

Lee Haydn met Major Rotzner in the reading room of the warship, and soon the two became friends.

Rotzner is the first mate of the Guanlun of the "Apal". Lee Haydn was reading a German-published magazine "Navy Lookout". In it, an article about the application of steam turbines written by the French was quite interesting, so he sat in a leather chair and read it happily.

At this time, Major Mark Rotzner happened to come in. He just needed to find an article in the magazine, so the two of them started chatting.

Rotzner graduated from the Royal Second Naval Mechanical Engineering College in Bora. He worked in the Naval Shipbuilding Office. He was a shipbuilding engineer. This is what made Lee Haydn very interested in him.

The two involuntarily talked about the protection cruiser "Queen Elizabeth" that the Austro-Hungarian car was being built. Due to obstruction by the Hungarian Parliament, the Austro-Hungarian Empire Navy has always developed slowly due to insufficient funds. Although the Imperial Navy once won the first maritime war in the era of human steam ironclad ships, time is no longer there. Now the weak Imperial Navy is far behind the enemy Italian Navy.

As early as 1882, the Italians built two ironclad ships with displacement of more than 13,000 tons and equipped with two 343 mm main guns, which reversed the decline caused by the failure of the Lisa Naval Battle and became an important force that cannot be ignored at sea.

Rotzner's words were quite dissatisfied with the performance of the "Queen Elizabeth". In this era, the British had begun to build "June"-class battleships with all-steel armor and displacement of more than 14,000 tons, while the Austro-Hungarian Navy was still struggling to build a budget of 4,000 tons of protective cruisers.

"If we meet the Italian Navy again, our fleet will probably not even have the power to fight back." Li Haidn said with a wry smile. He could not say that he had any deep feelings for the Imperial Navy, but it seemed that having a strong navy would make it easier to get foreign orders. You should know that selling warships is a large-scale arms business and profits are not bad.

"Since the fools in the Magyar Parliament are unwilling to allocate more funds to the Navy, we can only think more about technology," Rotzner said. "In fact, since we rarely build new warships, we are almost behind the times in naval technology."

"I believe that new technologies and inventions are built up by quantity and mistakes. Without sufficient practice, advanced warships cannot be built by imagination alone." Li Haidn nodded, then lit a cigar. In fact, he has a clear understanding of the future development direction of the main battleship. Since the appearance of the dreadnought, all the main battleships in the world will be outdated overnight. In fact, the Austro-Hungarian Empire still has time.

It seems that the Imperial Navy is currently developing slowly, which is not a bad thing.

What we need to do now is to prepare for the future and conduct research in advance. Perhaps the Imperial Navy may become the first country to be equipped with this new style and has overwhelming advantages in the main ship.

A "full-heavy main gun" battleship with a unified caliber? Lee Haydn didn't want to propose this concept so early. Thinking about the more than 40 British men and French people, and the more than 20 Italians' main ships built with huge sums of money all turned into defective products overnight. Lee Haydn couldn't help but laugh.

Lee Haydn turned the topic to the magazine he was reading. In fact, Rotzner's specialty was marine power, that is, the manufacturing of boilers and steam engines. What surprised him was that Rotzner actually had in-depth research on electric motors and steam turbine engines.

The turbines appeared much older than the steam engines that used cylinders. Before the steam engine was invented, the main source of power for the textile industry and flour processing industry was water turbines. The windmill mills everywhere in Europe were ancient wind turbines. The oldest steam turbines were made by scientists long before the steam engine was invented. Of course, it was just a simple device for the steam sprayed from the nozzle of the water bottle to drive the blades to rotate.

The modern concept of steam turbine appeared in the 1870s, but due to the speed problem, it was unable to be put into practical commercial applications until the invention of the generator. The high speed of the steam turbine was perfectly combined with the requirements of the generator, and in fact, the same was true. Until more than a hundred years later, steam turbines were still the main power plant for thermal power plants and even nuclear power plants.

Lee Haydn's "Steel Mann" Power Company is making some steam turbines to power the generators made by his electrical appliances, but no one can load it onto the ship yet, although many people want to do so.

"Where is the difficulty?" Lee Hayden asked.

"It depends on the speed. The speed of the steam turbine is 1500 to 2000 rpm, while the speed of the marine propeller needs to be low to increase the thrust, usually 120 to 360 rpm, otherwise the power attenuation will be too great." Rotzner said.

"This problem is not big, it can be achieved through a reducer."

"The problem is that high-precision gear processing is very difficult. In addition, it is difficult to find a ship to do experiments. Even a small boat requires tens of thousands of kronors, and ordinary researchers cannot afford this money."

"If you are interested in this, I am willing to provide some help." Lee Hayden said with a smile. The British man Parsons put the steam turbine on the ship was a few years later. Now his Parsons Navigation Steam Turbine Company has not been established yet.

Perhaps, the famous Turpingia will not appear again in this era?
