A week later

The number of high-ranking military and political officials who accompanied Li Fushou on the inspection was much smaller, and the senior army officials all stayed at the Balmarang base to hold high-level strategic and tactical seminars to study the position of tanks and other weapons in the army's strategy in the current era, the organization and application tactics, the direction of scientific and technological reform, and the application of a series of chassis.

After visiting the Semarang Biochemical Laboratory, most of the senior officials of the Ministry of the Interior stayed in the area for further investigation, and the relevant matters were highly confidential and should not be disseminated to the public.

Therefore, there were only a dozen attachés who followed Li Fushou to the Toubaolong base, mainly the high-level officials of the Ministry of the Interior, the Political Intelligence Bureau, and the Imperial Secretariat, all of whom were high-level officials involved in secrets.

The Toubaolang base is already 317 kilometers from the Bamarang base, which is located at the beginning of the winding mountain range, and continues a few kilometers into the vast Gobi Desert, and further into the desert.

Located in the heart of Tasmania, the Gobi Desert area is not large, about hundreds of square kilometers, and can only be regarded as a small desert, just in front of the Toubaolong base.

This section stretches from the desert Gobi to Linhai Town, from Toubaolong, Erbaolong, Semarang to Jiubaolong, a total of more than 370 kilometers, and there are many secret bases.

There are two runways in the Toubaolang base, which are in the shape of "=", connected by auxiliary roads in the middle, and a high command tower, which is one of the main facilities for aircraft testing.

About 10 kilometers into the mountains, you can see a small town in the mountain basin, only more than 800 residents, there is a cross street more than 300 meters long in the center of the town, surrounded by huge factories and a small thermal power plant.

The town is brightly lit at night, and scientific researchers in white coats can be seen everywhere, and it is a secret base for the development of special aircraft engines and flying machines, and the average education of the town's residents is the highest in the empire.

There are now 5 highly classified R&D projects here; The first is an airplane, the second is a 4-cylinder aviation piston engine, the third is a 6-cylinder V-shaped high-horsepower aviation piston engine, the fourth is a wireless rangefinder, and the fifth is a radar.

Needless to say, airplanes, wireless rangefinders and radars will be big killers in the future, and their role will not be inferior to that of tanks, and they will bring revolutionary changes to the military field.

In 1842, the Austrian physicist J.C. Doppler discovered the Doppler effect and envisioned building a machine based on this principle to detect weather and objects.

In 1887, when the German scientist Hertz confirmed the existence of electromagnetic waves, he had already discovered that electromagnetic waves would be reflected back when they encountered metal objects in the process of propagation, just like a mirror could reflect light, which is essentially the working principle of radar.

However, Hertz did not think of using this principle to study further, firstly because of financial constraints, and secondly, because of energy constraints.

At that time, Hertz was only a physics professor at a university, and he verified his theory under rudimentary experimental conditions, and there was no government or university research funding, which made it difficult to conduct follow-up in-depth research.

What's more, he died of poisoning in 1894 at the age of 37, and there was no follow-up research.

It is related to the in-depth study of electromagnetic waves, which is the most cutting-edge scientific and technological field, which requires the world's top scientific research equipment and a large number of scientific researchers to assist in the experiment, and it is possible to invest a large amount of money to see the results, and this is only possible.

At present, the research of scientific and technological personnel on electromagnetic waves is still in the early stage of deepening their understanding, and a variety of scientific experiments are carried out according to the principle of electromagnetic waves, and a feasible research and development road should be explored.

Previously, according to Hertz's electromagnetic theory, the scientific and technological personnel of Toubaolong base designed electromagnetic wave generators and receivers, and the latest set of tests proved that electromagnetic waves can be blocked, reflected and accepted, and Hertz theory has been confirmed to have great application prospects.

Experimental;

A beam of radio waves emitted by the electromagnetic wave generator is smoothly received by the receiver, and when there is an object in the middle of the two, the electromagnetic wave is interrupted.

When the obstructing object is steel or other substances, there are different degrees of diffuse reflection.

This proves the feasibility of the working principle of radar, and the next step is to have an in-depth understanding of the characteristics of electromagnetic waves, develop electronic components that adapt to electromagnetic waves, form a complete working system, and finally develop specific machines.

The exploration of the frontiers of science and technology is bound to be a long process.

Of the five projects, the only one that can see the results quickly is likely to be the wireless rangefinder.

This is because the empire has a big scientist in the radio field like Professor Tesla, and as long as he invests part of his energy, it is very likely to solve this cutting-edge scientific and technological problem.

It is a pity that Professor Tesla is now burdened with heavy scientific research tasks, and he has to guide more than 20 scientific research projects involving AC remote transmission, switching, grid connection, and diversion, as well as the development of large-scale rectifiers, inverters, and more than 10 types of power alternators, and also solve the problems in the construction of AC power grids at home and abroad.

The main purpose of the radio rangefinder is embodied in naval warfare, accurately measuring the distance and relative speed of the opposing ship, which is directly related to the hit rate and damage effect of artillery fire, which is a key technology that can change the times.

At the end of the 19th century

Radio technology has sprung up like mushrooms after a rain, and major inventions have appeared in various countries, which have promoted the rapid maturity of radio technology and entered commercial use, and it already has a fairly strong technical foundation.

1873 Scotsman. Maxwell developed the theory of electromagnetic fields, and he was the first to design a radio receiver and transmitter, which was published in the January 1898 issue of the London issue of the magazine Model Engineer and Amateur Electrician.

End of the 19th century

Ocean Kingdom World Communications Corporation has realized transpacific radio transmission with high-power and huge antennas, and has made great progress in the commercial field, and the relevant radio transmitting and receiving towers have been completed one by one, rapidly weaving a radio transceiver network all over the world.

meanwhile

In 1897, after losing the relevant patent lawsuit, the Italian scientist Marconi changed his technical route and used high-power antennas to realize transatlantic radio communication, and established the Marconi Communication Company in an attempt to take a share of the radio market.

The application of radio technology is the in-depth excavation of electromagnetic phenomena, and the black technology in front of Li Fushou is the radio rangefinder, which can be developed 10 years earlier than the original history, and will achieve the transcendence of the curve and truly establish the status of the maritime power of the ocean empire.

In a sense

If a breakthrough can be achieved in radio ranging technology, its significance is no less than that of rockets and missiles, and it will play a key role in changing the situation of maritime hegemony.

In the era of big ships and big guns

Generally speaking, the larger the instrument, the more accurate it is, and the optical rangefinder used on the Metropolis-class battleships has a height of more than 10 meters, which is an optical instrument with relatively accurate measurements.

The optical rangefinder is mainly aimed at the protruding parts of the enemy warship, such as the chimney and the conning tower, and uses this as a benchmark for ranging, and the distance data read from the combined rangefinder is the speed of the enemy ship judged by the vortex in the bow of the enemy's ship, which is very "inaccurate" and can only get an "approximate value".

After such an "approximation" is entered, the error is constantly accumulated on the crowded fire console, and finally the error is magnified to an unbelievable level after the shell is launched through a flight of tens of seconds.

Therefore, modern naval warfare emphasizes the density and coverage of firepower, and it is possible to hit a "straddle shot" or "close arrow shell" only after multiple rounds of artillery fire can it be correct, which means that the shooting data is correct, and it is only a matter of time before the enemy ship hits and there is a little bit of luck.

As the hegemon of the world's oceans, Britain attaches great importance to the development of warship observation and sighting equipment, according to confidential internal information obtained by Li Fushou;

The Royal Navy has invested heavily in the secret development of electrical conduction instruments, and it is about to succeed.

It will be able to command and control the turret rotation with electricity, and the control room will be located above the front mainmast signal tower. The detection data of the target was obtained by the FQ-2 optical rangefinder. After further data calculation, the data obtained is the change data of the target course and speed of the enemy ship, which is most input into the Vickers firing range clock through electrical conduction to guide the battleship's main gun to fire.

This is the latest application of electrification technology in warships, and it is a top-secret technology.

The confidential information that Li Fushou was able to obtain was the general application of the technical route of the British side, but there were no specific technical details, and the Germans also spent a huge amount of money on secret research in this regard, striving to achieve overtaking.

Because of this, Li Fushou saw the opportunity to surpass in the corner.

Huge ironclad battleships are not terrible, large-caliber artillery is not terrible, and the most terrible thing is that such a battleship is capable of firing accurate shells, which is an absolute nightmare for the enemy.

The British and Germans diverged in their technical routes, trying to transform their machinery with modern electrification, essentially relying on mechanical technology, which could improve the accuracy of their shots, but only to a limited extent.

Li Fushou's idea was to flip the table, and if the wireless rangefinder that appeared decades later could be invented in advance, and the enemy ship's target could be continuously and continuously measured, the enemy's ship's accurate course and speed information would be obtained.

The rest is simple, just mobilize the main artillery to bombard.

A very simple radio technology in later generations is a subversive cutting-edge black technology in today's world, which is enough to change the face of the world and the fate of many countries.

In many cases, it is not that the current era cannot give birth to the technology that will appear in later generations, but it is just because the vision of the times is limited and such an application field has not been thought of, such as radio ranging and radar technology.

There is another factor that cannot be ignored, and that is demand.

Aircraft do not pose a huge threat to national security, so what is the use of inventing radar?

Is it just to monitor the birds in the sky?
