Regarding the navy's technical data, especially the relevant data and information on the navy's technical equipment, even in such an internal meeting, Cheng Haifeng only briefly talked about it, and basically ignored some sensitive parts.
Of course, everyone here is not just a crowd watching the excitement, but they still heard some key information from his words.
First of all, in Cheng Haifeng's words, this new battery technology is very important, even more important for the navy than other services.
Although large surface ships are now equipped with generators, the power supply of electronic systems still mainly relies on battery storage. It can be said that the size of the battery is directly related to the power of various electronic devices on the ship.
Now generally speaking, the greater the power of this type of electronic equipment, the better the performance. However, it is often limited by the size of the ship and the power and power output, so the various electronic devices mounted on it are very limited.
Wu Hao's new battery technology can not only reduce the size, but it is also crucial for the space on the ship where space is at a premium. Moreover, the overall energy storage is much higher than that of traditional batteries, which means that it can support the work of more electronic devices.
What’s more, that is the current trend in ship power development, all-electric propulsion systems. Simply put, it uses battery power to power the propulsion motor to propel the ship forward. As for the battery power, it is generated and charged by a diesel generator or ignition generator equipped on the ship.
The all-electric propulsion system not only removes the main steam turbine unit and gearbox as well as related auxiliary machinery, but also reduces the noise of the ship. At the same time, each component of the system can be easily modularized, which greatly improves cabin utilization, saves space on the ship, and reduces the displacement of the ship.
With the application of high-strength, lightweight composite materials in propulsion motors and the continuous breakthroughs in high-power, small-size, and lightweight propulsion motor technology, all-electric propulsion technology will be widely used on all types of ships in the future.
Compared with traditional diesel-burning wheel sets, electric drive systems are more economical and environmentally friendly. It consumes less fuel and can significantly improve the ship's concealment and endurance. Moreover, 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 the future equipment of high-power laser weapons.
As we all know, electromagnetic weapons and laser weapons are key cutting-edge weapons and equipment fields that are currently being studied by various military powers in the world. Whether it is electromagnetic weapons or laser weapons, 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 ordinary ships to support the continuous consumption of high-power electromagnetic guns and laser weapons.
Even if the miniaturization problem is solved, it consumes huge amounts of power. With the current power supply capacity of ordinary ships, it takes a lot of time to charge each time, and it is not yet 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 such high-power electromagnetic weapons and laser weapons to be put on ships.
In fact, the above is important even if it is said to be important, but it is not that urgent to say that it is not important. What really makes the navy more urgent is the need for submarines.
Although Cheng Haifeng never introduced the 309 project, Lin Hongwen, the deputy chief engineer, did not mention it at all. But everyone here has basically guessed what this 309 project is.
The only deputy chief engineer who pays so much attention to this new battery technology and made a special trip to attend the meeting is the submarine project.
The all-electric propulsion system is the development trend of current or future submarines, and it is also a cutting-edge technology that the navies of various countries are vigorously researching and developing.
In fact, there has always been a question, that is, are nuclear-powered submarines really propelled by nuclear power?
This sentence is correct or not. 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 the high temperature generated by the nuclear reactor can generate steam in the steam engine, then drive the steam turbine, drive the generator to generate electricity, and then drive the motor to drive the propeller.
Compared with the first one, the second technology is more advanced and is currently the main drive technology used by nuclear-powered submarines in major countries.
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 and has poor controllability, it is impossible to precisely control the power.
Therefore, a set of batteries 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 first, and then the battery is supplied to the propulsion motor. After such a cycle, the power becomes more stable, and the control operation becomes more flexible and safer.
Of course, not everyone can afford such a nuclear-powered submarine. Currently, only the five gangsters, no, the five permanent members can afford it.
Some other countries were ambitious and wanted to develop, but they sank before leaving the port and became an international joke.
Therefore, these other countries that are drooling can only choose the more economical diesel-electric and AIP submarines.
Instead of relying on air propulsion engines, AIP submarines can lurk underwater for a longer period of time and have better concealment than ordinary conventional submarines. Their combat effectiveness has been doubled, and they are already close to the level of "quasi" nuclear submarines.
The navies of most countries cannot afford expensive nuclear submarines due to their own military expenditures and small combat areas, so AIP submarines have become a good choice for them. This will set off a restless undercurrent in the tranquil depths of the ocean.
Of course, with the continuous advancement of electric drive technology, the future of diesel electric vehicles seems to be catching up in recent years. Moreover, the comprehensive drive system solution driven by AIP+electric power has also become a key research area 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, thus increasing the submarine's sailing speed, making it faster and more flexible underwater.
Second, the increase in power storage means that the submarine's range is increased. Reducing the number of times the generator generates electricity makes the submarine sail more quietly underwater, which is crucial to the submarine's underwater combat performance.
Perhaps 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.
