Vol 2 Chapter 265: Long-awaited navy

Regarding the technical data of the navy, especially the relevant information about the technical equipment of the navy, even in such an internal meeting, Cheng Haifeng only gave a brief overview. Some sensitive parts are basically general.

Of course, everyone in this room is not looking at the lively eating melon crowd, but still hear some key messages from his words.

First of all, in the words of Cheng Haifeng, that is that this new battery technology is very important, and even more important to the Navy than other services.

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

Now generally, the greater the power of such electronic equipment, the better the performance. However, it is often limited by the size of the ship and the influence of power and power output, so the various types of electronic equipment carried on it are very limited.

And Wu Hao's new battery technology can not only reduce the size, it is very important for the space above the ship. And the overall energy storage is much higher than traditional batteries, which means that it can support more electronic equipment work.

Then there is the current trend of ship power development, all-electric propulsion systems. In simple terms, it uses the power of the battery to power the propulsion motor to propel the ship forward. As for the power of the battery, the diesel generator or the ignition generator equipped on the ship is used to recharge the electricity.

The all-electric propulsion system not only removes the main steam turbine unit, the gearbox, and related auxiliary machinery, but also reduces the ship's noise. At the same time, each component of the system can be easily modularized to greatly improve the utilization rate of the cabin, save space on the ship, and reduce the displacement of the ship.

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

Compared with traditional diesel-fired wheel sets, electric drive systems are more economical and environmentally friendly. Fuel consumption is low, which can significantly improve the concealment of the ship and improve its endurance. And the response speed is faster, which is more conducive to the maneuver of the ship.

Finally, and most importantly, that is to greatly increase the capacity of the ship's power station and lay the foundation for the future equipment of high-power laser weapons.

Everyone knows that electromagnetic weapons and laser weapons are the key cutting-edge weapons and equipment fields that various military powers in the world are scrambling to study. Regardless of whether it is an electromagnetic weapon or a laser weapon, the power demand on the ship is huge.

With current technology, unless it is a nuclear-powered aircraft carrier equipped with a nuclear reactor, it is difficult for general 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 capability of ordinary ships, it takes a lot of time to recharge each time, and it is not really practical.

If equipped with this battery, then its power supply will increase by half compared to the previous, which will undoubtedly lay the foundation for such high-power electromagnetic weapons and laser weapons to ship.

In fact, the above is important and important, and it is not so urgent to say that it is not important. And what really makes the Navy more urgent is the needs of the submarine.

Although Cheng Haifeng never introduced the 309 project, Lin Hongwen, the deputy chief engineer, said nothing. But basically everyone here guessed what the 309 project was.

The Deputy Chief Engineer who can pay so much attention to this new battery technology and make a special trip to attend the conference is probably the only 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 field technology vigorously researched and developed by the navies of various countries.

In fact, there has always been a question: Is nuclear-powered submarines really propelled by nuclear power?

This statement is not true, in fact, a nuclear power plant cannot directly propel a submarine forward. Instead, the high temperature generated by the nuclear reactor makes the steam in the steam engine drive the steam turbine to drive the propeller.

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

Compared with the first, the second technology is more advanced, and it is also the main driving technology currently used by nuclear power submarines in major countries.

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

So a battery and a power control system are added between the two. In other words, the electricity generated by the generator must 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 ~ www.readwn.com ~ Of course, such nuclear-powered submarines are not affordable for everyone, and currently only The five big hooligans, no, can only be played by Wuchang.

Some other countries are ambitious and want to develop. As a result, they sink before they leave Hong Kong and become an international joke.

So these drooling other countries can only choose their targets on the more economical diesel and AIP submarines.

It does not rely on air propulsion engines. It can be submerged for a longer period of time. AIP submarines, which are more concealed than ordinary conventional submarines, have doubled their combat effectiveness and are close to the level of "quasi" nuclear submarines.

The navies of most countries are limited by their military expenditures and small combat waters. AIP submarines have become a good choice for them because they cannot afford expensive nuclear submarines. This will cause a restless undercurrent in the depths of the quiet ocean.

Of course, with the continuous advancement of electric drive technology, the future of diesel power seems to catch up. In addition, the comprehensive drive system scheme driven by AIP + electric power has also become a key research area of ​​navies in various countries.

No matter what kind of driving scheme, the level of battery performance is directly related to the performance of a submarine.

If the performance of the battery is improved and the amount of stored power is increased, then a more powerful propulsion motor can be driven, thereby increasing the speed of the submarine, making it faster and more flexible under the water.

Second, that is the increase in power storage, which means that the range of the submarine is increased. Reducing the number of times the generator generates power makes the submarine quieter under water, which is critical to 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 will quit his job and rushed over to participate in this technical demonstration and practical seminar.
