At the beginning of June, Yang Jie also came to a high-power pulse power technology research and development center of Huaxing Technology Group Company on the outskirts of Honghu City.

This R&D center is jointly established by a number of institutions and enterprises such as Huaxing Technology Group Corporation and Naval University of Engineering.

Among them, Professor Ma Weimin served as the technical director of this R&D center, which is also the largest strong electromagnetic pulse experimental facility base in China.

This R&D center was established in 03 years and has been continuously developing high-power pulse power technology for more than 6 years.

A group of R&D personnel led by Professor Ma Weimin entered this R&D center very early, and Nanao Group Company and Aode Technology Co., Ltd. also dispatched a group of technicians to conduct R&D in this R&D center.

The construction of this R&D center was decided by Yang Jie and Professor Ma Weimin after in-depth discussions, and this high-power high-power pulse power supply technology is to make technical preparations for high-energy weapons on ships, and the other is to research and develop technology in the field of power system peak regulation.

The navy was hoping to be able to develop a large-caliber and long-range strike electromagnetic cannon weapon system for the navy by the Naval Engineering University, and began to develop technology in this area very early, but high-power pulse power supply technology is an emerging discipline, especially the major project for engineering applications, the key indicators are higher than the existing technology, there is no experience in China for reference, and foreign countries are strictly sealed.

The Naval University of Engineering wanted to carry out experiments in this area, and for this reason, it searched all over the domestic manufacturers, and ran into walls everywhere, and basically no manufacturers were willing to take this job.

Because the design concept of the device is completely different from the conventional method, the previous experience cannot be applied to this device.

At that time, the Naval University of Engineering also found Yang Jie, and he had a detailed discussion with Professor Ma Weimin and others on the design scheme, manufacturing and test methods, etc., and Yang Jie then built a large-scale experimental base in Honghu City out of his own pocket and established this research and development center.

In order to meet the high energy emitted by high-energy weapons, the power supply of these high-energy weapons comes directly from the pulse to form a network power supply, and the power supply energy comes from the pulse capacitor, and the energy of the pulse capacitor comes from the power supply network.

However, it is impossible to achieve the launch of high-energy weapons such as electromagnetic guns with conventional pulse power supplies, because if the muzzle kinetic energy reaches 32 megajoules, then according to the rate of fire of 5 rounds per minute, it means that the instantaneous power reaches 42.6 megawatts, and no weapon platform grid can reach such a high power.

Ma Weimin and other experts also put forward the technical scheme of high-power hybrid energy storage device, and put forward the innovative idea of multi-stage energy storage to reduce the power demand for reducing the power of the ship power grid, and the energy storage device includes flywheel energy storage device, supercapacitor battery, and the storage device is managed at different levels, which can greatly reduce the instantaneous power demand of the power grid and avoid large fluctuations in the power grid.

Yang Jie is very much in favor of this technical solution, over the years this R & D center has carried out a lot of technical research and development in high-power pulse power technology, and many subsidiaries of Huaxing Technology Group Company have undertaken the research and development of many subsystem technology and equipment.

For this purpose, Aode Technology Co., Ltd. has developed high-performance graphene supercapacitor batteries and graphene solid-state ternary lithium battery packs. 12

Huaxing Technology Group Co., Ltd. has now carried out mass production on graphene three-dimensional foam materials, and now the established production line has been able to provide tens of thousands of tons of three-dimensional graphene materials every year.

The instantaneous discharge performance of this combined energy storage power battery pack is required to reach more than dozens of times the battery capacity, which has reached the previous design goal, and after the further improvement of this R&D center, the system volume and weight are also greatly reduced, and there is still room for further improvement.

Now this combined energy storage system has begun to be used in energy storage power stations by Nanao Group Company, which has greatly improved the peak regulation capacity, and other subsidiaries have also begun to use this set of energy storage technology, such as servers and communication equipment, as well as fuel cell vehicles and other products.

In addition, the technical team led by Professor Ma Weimin is mainly committed to the research and development of medium and large-capacity integrated flywheel energy storage modules to meet the needs of peak regulation and high-energy weapons of the ship's integrated power system, and has developed a 50 MW power energy storage prototype so far.

In the R&D center, after Yang Jie saw this half-room-sized flywheel energy storage device, he also asked Professor Ma Weimin in detail about the technical details of the prototype.

In fact, there are two main branches of existing flywheel energy storage technology, the first branch is the large-capacity flywheel energy storage technology represented by contact mechanical bearings, the main characteristics of this technical equipment are to store kinetic energy, release power, and are generally used for short-term high-power discharge and power peak shaving occasions.

The second branch is the small and medium-capacity flywheel energy storage technology represented by magnetic levitation bearings, which is mainly characterized by compact structure and higher efficiency, and is generally used as flywheel batteries, uninterruptible power supplies, etc.

Professor Ma Weimin also selected the technical route of magnetic levitation flywheel battery after comprehensively considering the advantages of Huaxing Technology Group in electromagnetic technology.

Overseas Western countries in the large-capacity flywheel energy storage unit in many countries have large-capacity energy storage unit applications, manufacturing and assembly technology has been relatively mature, a single energy storage from tens to thousands of megajoules range, the release of peak power from tens of megawatts to thousands of megawatts range, mostly by discrete motors, generators, energy storage flywheels using coupling connection composition.

Because these countries have developed relatively early in this area, they basically use mechanical contact bearings, which are generally very large in size, and the energy conversion efficiency is not particularly ideal.

In this regard, Eagle Sauce is still ahead of the curve, and has developed a compensation pulse generator with a peak power of 1,000 megawatts, which is exactly for the Eagle Sauce military to use as a millisecond-level high-power pulse power supply for railguns.

Professor Ma Weimin didn't want to run behind the butt in these countries, and of course Yang Jie didn't want to, so he let the R&D department of the research and development of magnetic bearing devices and the technical departments such as the Machine Tool Research Institute under Ruixing Technology all participated, and it took more than four years to overcome the magnetic bearing technology and make it.

This set of magnetic levitation bearings adopts magnetic levitation plus vaporization bearing technology, the most difficult thing is that in fact, it is a special process to strengthen the hardness of the shaft sleeve of the oil-impregnated bearing, in order to overcome the shortcomings of the oil-impregnated bearing that it is not resistant to high temperature.

The bearing technology research and development team under the Machine Tool Research Institute has done tens of thousands of experiments to master this extremely difficult processing technology.
