Introduction
"Book of Rites" has a saying: "Gou Rixin, and daily new, new day by day". In the current international society, countries are competing at various levels. Among them, competition in the military field is particularly prominent. How to innovate and develop more advanced military equipment is the firm goal of each country.
01
When it comes to the military field, we have to mention the aircraft carrier, an important military equipment. The aircraft carrier, as a symbol of the modern nation’s comprehensive strength, is a combat platform with comprehensive sea, land and air strike capabilities. Z1z
deserves the title of maritime hegemon due to its powerful functions suitable for long-distance combat. Since the combat capability of the aircraft carrier is so powerful,
, as the driving force for the aircraft carrier, is bound to be the top priority for the research and manufacture of aircraft carriers in various countries
. However, compared with the power of aircraft carriers in various countries in the world,
someone once asked whether the power of Chinese aircraft carriers is the most backward ?
▲The aircraft carrier
on the sea In fact, the aircraft carrier presents its current form and has undergone many innovations. Both the appearance design and the power source have been updated many times. In the beginning, the aircraft carrier was refitted with obsolete ships. Compared with the carefully developed and designed aircraft carriers,
naturally has a clear gap. These early aircraft carriers are much smaller in appearance than the current ones, and
is also mostly used in power sources. The power mode of kerosene mixed-burning boiler and steam turbine. This backward power method has many drawbacks. The thick black smoke from the large boiler will not only cause serious pollution to the environment, but also is not conducive to the hiding of the army.
▲The black smoke emitted by the old aircraft carrier
aircraft carrier This obvious shortcoming did not have a major change until the end of World War II. It developed from the power mode of kerosene mixed-fired boiler and steam turbine to the conventional oil boiler and steam turbine. Power mode. Z1z
can even say that the aircraft carrier ushered in the peak of development again during this period. Because
had already appeared at that time nuclear reactor power mode, and the technical level of this nuclear reactor power mode is undoubtedly the highest,
it can continuously To deliver steam to an aircraft carrier, the electricity produced can provide a supply for a small city.
02
According to the "History of the U.S. Navy's Supercarrier Development", the current total power generation of the latest Ford-class aircraft carrier has reached 172 megawatts, while the total power generation of the Liaoning ship is still around 20 megawatts.
It is undeniable that
China's aircraft carriers are still relatively behind in many aspects. For example, in terms of power, the power method used by Chinese aircraft carriers is still the most traditional oil-fired boiler and steam turbine.
uses oil-fired boilers to burn heavy oil to generate high-pressure steam, thereby driving the steam turbine inside the aircraft carrier, which allows the steam turbine to generate kinetic energy, which then acts Go to the propeller at the stern of the ship, and then do reverse thrust on the water to make the aircraft carrier move forward.
It can be seen from this that, in such a complicated power conversion process, if you want to drive such a giant aircraft carrier to sail on the water, even to reach a certain speed, it is necessary to add a large amount of heavy oil inside the oil-fired boiler, and continue Keep the body temperature of burning oil.

It is reported that the traditional power mode adopted by the
Chinese aircraft carrier determines a prerequisite for the operation of the aircraft carrier, that is, it must be burned for 48 hours before leaving the port. The driving process of a nuclear-powered aircraft carrier is much simpler in comparison. It only needs to warm up for a few hours to make the aircraft carrier move forward. This greatly saves the time and cost of departure
. In addition, the energy produced by the
nuclear reactor is much higher than that of the oil-fired boiler. It can support the aircraft carrier for a longer time at sea. The
greatly enhances the combat capability of the aircraft carrier, and the energy efficiency of nuclear power is compared Fuel is also much higher.
Therefore, in response to the aforementioned question: "Is the power of Chinese aircraft carriers the most backward", American experts once said that it takes 48 hours to burn each time out of port. The shortcomings are too prominent and the gap is too prominent.
▲ Inside the nuclear reactor
It should be pointed out that the reason for the relative backwardness of China's aircraft carriers is that they started too late. When other countries already have an aircraft carrier fleet, China has just started its plan to build an aircraft carrier.1z
, the gap between these decades can never be equalized in a few years.
China currently has two conventionally powered aircraft carriers. It can be seen that the development speed of China's aircraft carriers is astonishing
. Such a development process is also unique in the world. Therefore,
China's aircraft carrier application of more advanced nuclear reactors as a power mode is bound to be just around the corner.
▲British aircraft carrier
It is worth mentioning that in addition to the two power modes of oil-fired boilers and nuclear reactors, the UK has developed a new power mode, which uses gas turbines and diesel engines. Although
looks similar to the traditional power method, in fact there are obvious differences between the two. Compared with
, it is much more advanced. Of course, its efficiency has not reached the height of nuclear power. There are naturally many loopholes in such an unconventional power method.
regards the gas turbine as the main engine. Although it also has the advantages of providing a large amount of electric power in a short time and speeding up the aircraft carrier quickly, it is much worse than the oil boiler and steam turbine in terms of energy efficiency.
Although there are many shortcomings in the new power mode of British aircraft carriers, it also proves the continuous innovation of aircraft carrier research and development in the current world. As the "Book of Changes · Qian · Classical Chinese" said: "Work all day long, keep pace with the times". The developing countries continue to look for more possibilities.
Conclusion
Although China lags behind countries such as the United States in the development of aircraft carriers, China attaches great importance to the development of aircraft carriers and the results are remarkable. This is the result of countless Chinese scientists day and night. In fact, the rapid development of China's aircraft carrier technology can also see the development of China's entire science and technology. China's scientific and technological progress has been shown in various aspects, such as the gradual popularization of 5G technology in people's daily lives. In short, China's military power will be stronger, China's scientific and technological power will be stronger, and China's comprehensive national power will be stronger.
