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

Of course, everyone present is not a crowd of melon-eating people who watch 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 branches of the military, it is especially important for the navy.

Although large surface ships are now equipped with generators, they still rely heavily on batteries to store electricity for their electronic systems. It can be said that the size of the battery is directly related to the power of various electronic devices on the ship.

Now, in general, the more powerful this type of electronic device is, the better the performance. However, it is often limited by the size of the ship and the influence of electric 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 volume, which is crucial for the space on the ship, which is at a premium. And the overall energy storage capacity is also much higher than that of traditional batteries, which means that it can support more electronic devices.

And then there is, that is the current trend of ship power development, all-electric propulsion system. To put it simply, it uses battery power to power the propulsion motors, thereby propelling the ship forward. As for the battery, the diesel generator or ignition generator installed on the ship is used to generate electricity.

The all-electric propulsion system not only removes the main turbine unit and gearbox and related auxiliary machinery, but also reduces the noise of the ship. At the same time, the modularization of each component of the system greatly improves the utilization rate of the cabin, saves the space of 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 to traditional diesel-fired wheelsets, electric drive systems are more economical and environmentally friendly. Low fuel consumption can significantly improve the concealment of the ship and improve the endurance and other advantages. Moreover, the reaction speed is faster, which is more conducive to the maneuver of the ship.

Last but not least, it 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.

As everyone knows, electromagnetic weapons and laser weapons are the key areas of cutting-edge weapons and equipment that various military powers in the world are vying to study. And whether it is electromagnetic weapons or laser weapons, the demand for electricity on ships is huge.

With 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 though the problem of miniaturization has been solved, it is due to the huge power consumption. With the current power supply capacity of ordinary ships, it takes a lot of time to recharge each time, and it is not really practical.

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

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 anxious should be the demand for submarines.

Although Cheng Haifeng never introduced the 309 project, Lin Hongwen, the deputy chief engineer, did not mention anything. But everyone here basically guessed what this 309 project was.

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

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

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

This sentence is not true or not, in fact, nuclear power units do not directly propel submarines forward. Instead, the high temperature generated by the nuclear reactor generates steam in the steam engine and drives the steam turbine to drive the propeller.

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

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

This technology does not directly drive the electric motor to drive the propeller forward by using electricity generated by a steam turbine generator. Because the power generated by the steam turbine generator is not stable, the controllability is relatively poor, and the power cannot be accurately controlled.

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

Of course, not everyone can afford to play nuclear-powered submarines like this, and at present, there are only the five hooligans, no, the five permanent members.

Other countries were ambitious and wanted to develop, but they sank before they even left the port, becoming an international joke.

So the other countries that drooled had no choice but to target the more economical diesel-electric and AIP submarines.

AIP submarines that do not rely on air-propulsion engines, can be lurking underwater for a longer time, and have better concealment than ordinary conventional submarines, have doubled their combat effectiveness, and are already close to the level of "quasi" nuclear submarines.

The navies of most countries are limited by their own military spending and the small operational area cannot afford to buy expensive nuclear submarines, so AIP submarines have become a good choice for them. This creates a restless undercurrent in the depths of the tranquil ocean.

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

No matter what kind of drive scheme it is, the performance of the battery is also directly related to the performance of a submarine.

If the performance of the battery increases and the storage capacity increases, then it can drive a more powerful propulsion motor, which increases the speed of the submarine, making it faster and more agile to travel underwater.

Second, it is an increase in the storage capacity, which means an increase in the range of the submarine. Reducing the number of times the generator generates electricity makes it quieter for the submarine to navigate underwater, which is critical for the submarine's underwater combat performance.

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