Military Technology

Regarding the technical information of the navy, especially the relevant information of the navy's technical equipment, even in such an internal meeting, Cheng Haifeng only talked about it in general, and basically generalized some sensitive parts.

Of course, the people here are not melon-eaters watching the excitement, but they still heard some key information from his words.

First of all, in the words of Cheng Haifeng, this new battery technology is very important, even compared to other military services, it is especially important for the navy.

Although large surface ships are now equipped with generators, they still mainly rely on battery storage in terms of power supply for electronic systems. It can be said that the size of the battery is directly related to the power of various electronic equipment on the ship.

Now in general, the more power these types of electronic devices have, the better they can perform. However, it is often limited by the size of the ship and the influence of power and power output, so the various electronic equipment on it is very limited.

And Wu Hao's new battery technology can not only reduce the size, but it is very important for the space above the ship where every inch of land is expensive. Moreover, the overall energy storage is much higher than that of traditional batteries, which means that it can support more electronic devices.

What's more, that is the current trend of ship power development, all-electric propulsion system. Simply put, it uses the power of the battery to power the propulsion motor to propel the ship forward. As for the power of the battery, it is charged by a diesel generator or a combustion generator equipped on board.

The all-electric propulsion system not only removes the main steam turbine unit, gearbox and related auxiliary machinery, but also reduces the noise of the ship. At the same time, each component of the system is easy to realize modularization, which greatly improves the utilization rate of the cabin, saves space on the ship, and reduces the displacement of the ship.

With the application of high-strength and light-weight composite materials in propulsion motors, and the continuous breakthrough and development of high-power, small-size, and light-weight propulsion motor technology, all-electric propulsion technology will be widely used in various types of ships in the future.

Compared with the traditional diesel ignition wheel set, the electric drive system is more economical and environmentally friendly. The fuel consumption is low, and it can significantly improve the concealment of the ship and improve the endurance and many other advantages. And the reaction speed is faster, which is more conducive to the maneuvering of the ship.

The last and most important thing is to greatly increase the capacity of the ship's power station and lay the foundation for future equipment of high-power laser weapons.

We all know that electromagnetic weapons and laser weapons are the key fields of cutting-edge weapons and equipment that various military powers in the world are vying to research. And whether it is electromagnetic weapons or laser weapons, the power demand on ships is huge.

With the current technology, unless it is a nuclear-powered aircraft carrier equipped with a nuclear reactor, it is difficult for ordinary ships to support the continuous consumption of high-power electromagnetic guns and laser weapons.

Even if the miniaturization problem is solved, the power consumption is huge. With the current power supply capacity on ordinary ships, it takes a lot of time to recharge each time, and it cannot be truly practical.

If equipped with this battery, its power supply will be increased by half compared to before, which will undoubtedly lay the foundation for the launch of such high-power electromagnetic weapons and laser weapons.

In fact, the above things are important and important, and it is not so urgent to say that they are not important. What really makes the navy more urgent should be the need for submarines.

Although Cheng Haifeng never introduced the 309 project, Lin Hongwen, the deputy chief engineer, didn't mention it either. But everyone here basically guessed what this 309 project is.

The only deputy chief engineer who can attach so much importance to this new battery technology and come here to attend the meeting is probably only the submarine project.

The all-electric propulsion system is the development trend of submarines today or in the future, and it is also a cutting-edge technology that is vigorously researched and developed by navies of various countries.

In fact, there has always been a question, that is, are nuclear-powered submarines really propelled by nuclear power?

This sentence is right or wrong, in fact, the nuclear power plant cannot directly propel the submarine forward.

Instead, the high temperature generated by the nuclear reactor generates steam in the steam engine and then drives the steam turbine to drive the propeller.

Or use the high temperature generated by the nuclear reactor to generate steam in the steam engine to drive the steam turbine, drive the generator to generate electricity, and then drive the motor to drive the propeller.

Compared with the first type, the second type of technology is more advanced, and it is also the main driving technology used by nuclear-powered submarines of major countries.

And this technology does not use the electricity generated by the steam turbine generator to directly drive the motor to drive the propeller forward. Because the power generated by the steam turbine generator is not stable, the controllability is relatively poor, and the power cannot be precisely controlled.

So a set of batteries and a power control system are added between the two. In other words, the electricity generated by the generator must first be stored in the battery, and then the battery is supplied to the propulsion motor. After such a lap, the power is more stable, and the control operation is more flexible and safer.

Of course, not everyone can afford a nuclear-powered submarine like this, and currently only the five hooligans, no, Wuchang can afford it.

Some other countries were ambitious and wanted to develop, but they sank before leaving the port, which became an international joke.

So these drool-worthy other countries can only choose the more economical diesel-electric and AIP submarines.

Instead of relying on air-propelled engines, AIP submarines can stay submerged for a longer period of time and have better concealment than ordinary conventional submarines. Their combat effectiveness has doubled, and they are already close to the level of "quasi" nuclear submarines.

The navies of most countries cannot afford high-priced nuclear submarines due to their own military expenditures and narrow combat sea areas, so AIP submarines have become their good choice. This makes the quiet depths of the ocean set off another restless undercurrent.

Of course, with the continuous advancement of electric drive technology, in recent years, the future of diesel-electricity seems to have a tendency to catch up again. Moreover, the comprehensive drive system scheme driven by AIP+ electric power has also become a key research field for navies of various countries.

Regardless of the driving scheme, the performance of the battery is directly related to the performance of a submarine.

If the performance of the battery is improved and the storage capacity is increased, it can drive a more powerful propulsion motor, thereby increasing the speed of the submarine, making it faster and more flexible underwater.

Second, that is the increase in storage capacity, which means that the range of the submarine has been improved. The number of power generation of the generator is reduced, making the submarine sail more quietly underwater, which is crucial for the underwater combat performance of the submarine.

I am afraid that it is precisely because this new battery technology is so important that Lin Hongwen put down the work at hand and rushed over to participate in this technical demonstration and practical seminar.
