What's new

Chinese electromagnetic launcher (railgun, coilgun .etc) informational pool

This video was posted on Dec 2017 and quoting Ma Weiming reported claiming China is at least 10years ahead of US and a real railgun has long tested on Inner Mongolia. Many people thought he is BS or boasting but fast forward 2 months later...

The video is a mixture of many "would be" scenarios. First you have to understand railgun projects are not led by Prof. Ma, not even the same research institute. What Ma was doing is the power distribution system that affects railgun. One could argue that Prof. Ma's work is also decisive in EM catapult on a carrier, but remember Prof. Ma does not lead the carrier project, not even the EM catapult project. He does not work on specific weaponry, only the power distribution system.

So, for Prof. Ma giving out estimates on railgun can only be very general. He said the "Medium Voltage DC Power Distribution" is 10 years ahead of US, but you have to remember China does not yet have a warship that uses IEP, therefore Prof. Ma's system is yet to be applied on a ship. For more info about this topic here is a good video intro


At 10:50 he explained the advantage of a DC (power distribution) system. He said the AC bus driving EMALS on USS Ford is workable. But the same system is too heavy for a 7000 ton destroyer if you want to host an EM weapon like a railgun. One can conclude once you have a mixture of such EM weapons such as a laser gun plus a railgun, you will have even more problems. Ma's solution will make it possible for Type 055 to mount a railgun, and it will be the same type of solution USN is pursuing.

Quite fair and rational. The key point is something like I can make an outer solar system spacecraft if I have powerful engines. Now you have the engine!

It's an important milestone for the EM technology roadmap though there are many problems to deal with. Isn't it?
The 'would be' causes are backed up by EMALS, railgun prototypes even there will appear EM launchers that can launch satelites. I just believe in Prof. Ma's claim.

It's just an option game for you before you surpass Prof. Ma's achievement in EM technology field. Right? Your choice again. lol

I think Prof. Ma is absolutely a talent and a teacher that can push Chinese Naval power to be the world leader some day. But as a system, we also need to improve the turbine (QC280), each individual weapon system (including carrier-based jets), and more importantly, training. USN always have the advantage in actual combat experience, PLAN should be humble and try to learn. But there is no denial PLAN may have some very important ships that performs better than the corresponding USN ships before 2035.

I actually think the Chinese (solid state) laser weapon will be disclosed in the next two years! The point is China only wants order, and less hostility in West Pacific, not global dominance. With that goal, the process can be quicker and more effective.

Once you are #2 you always focus on things you do well. Once you are #1 you will notice your shortcomings more. That is just human nature.
 
Is China's space laser for real?
It's not a Death Star super laser. It's a space broom.

It's not this.
China's space broom isn't the Death Star super laser. It's an orbiting satellite with a laser only powerful enough to heat up pieces of space junk, so that they change course burn up in the atmosphere.

In a recent article in scientific journal Optik, a faculty member at China's Air Force Engineering University proposed building a laser-armed satellite, a "broom" to do battle with the pernicious problem of space debris.

Laser-armed satellites, naturally, generate a lot of attention, and so the proposal of Quan Wen and his co-authors has made its way into several splashy headlines. But it's more than hype. The concept addresses a real (and growing) problem: there's something like 17,852 artificial objects orbiting earth (PDF), and an estimated 300,000-plus pieces of space debris larger than a marble. At the fast orbital velocities up in space, even large craft like the International Space Station have to maneuver out of the way of small objects to avoid catastrophic damage.

Quan's research looks at the efficacy of a hypothetical laser operating near the infrared spectrum. It would blast away targeted space debris for a couple minutes, at a rate of twenty bursts of laserfire a second. That amount of energy would be sufficient to vaporize part of the object's mass. Contrary to public imagination, space laser brooms like the one proposed don't actually vaporize space debris, but rather "burn off" a chunk. This would create sufficient kinetic force from the chemical combustion to change the object's orbit. With that change in direction, the debris will quickly reenter the atmosphere and burn up. Because of atmospheric distortion, it's much more effective to zap space debris with a satellite than, say, a ground-based laser.

Of course, for now it's all theory. The laser broom would need to be actually mounted on a satellite and lofted into orbit to test its true efficacy. And even then, it'd still face some legal grey areas (technically speaking, space debris are still the property of owners of the satellites they originated from, which is very, very difficult to track) as well as major suspicion about the idea of implementing a weapon-like technology up in space.

Like many others, China's space program has both civilian and military applications. (The AoLong 1 satellite, for example, has a robotic arm for mechanically de-orbiting space debris that has has potential as an anti-satellite sabotage technology.) And so there's an obvious question: can the space laser broom be an anti-satellite weapon? It's certainly possible, though a cost-effective laser broom would need to be small—just big enough to take care of small debris. To quickly deal serious damage to enemy spacecraft, one would need a much larger space laser weapon; perhaps an orbital battlemoon?

Dr. Zhang posted a journal on IEEE about hybrid energy storage system for railgun in 2015, this might be the early research. Here is the introdunction:

“Chemical stored energy + physical stored energy” mode is adopted to increase instant power in new-style hybrid energy storage technology, which decreases the power need of shipboard railgun to power grid, this mode takes full advantages of high energy density for chemical stored energy and high power density for physical stored energy.The basic principle is that energy from power grid is firstly transferred to battery within a relatively long time, and then the energy is transferred to capacitors within a short time, after that capacitors discharge to electronic load quickly, accordingly the instantaneous power is amplified. Academician Ma Weiming from Naval University of Engineering put forward that shipboard railgun should use hybrid energy storage for power supply, and led the development of correlation studies.

I can be sure, USN spy satellite are watching closely of such test.

There is another journal that posted in 2017. However, ther size of the journal is too large that I cannot upload it. So I seperate it to two part:

CHINA SAYS IT IS TESTING WORLD’S FIRST RAILGUN AT SEA, CONFIRMING LEAKED PHOTOS OF ELECTROMAGNETIC WEAPON
BY TOM O'CONNOR ON 3/14/18 AT 1:25 PM
China has indirectly confirmed that it was testing what would be the world’s first warship-mounted railgun, a powerful electromagnetic weapon that even the U.S. Navy has struggled to bring to sea, according to official media reports.

China’s official military website published a report Thursday featuring Zhang Xiao, an associate research fellow at the People’s Liberation Army Navy University of Engineering. Zhang was described as a leading figure in Chinese efforts to develop “electromagnetic launching technology.”

She was also called a central part of Chinese Navy Rear Admiral Ma Weiming’s elite research team, which has contributed to some of the country’s top military achievements, including aircraft carriers and nuclear submarines, according to an article published Monday by Chinese Communist Party newspaper The Global Times. In the video, Zhang was awarded a National March 8 Red Banner for her recent accomplishments.

“After hundreds of failures and more than 50,000 tests,” Zhang successfully developed the largest “repeating power supply system” in the world, the report said, as translated by China’s ruling party organ on Monday.

One of several undated images widely shared on social media shows a device identified by analysts as an electromagnetic railgun mounted on Chinese Type 072III-class landing ship Haiyang Shan, at the Wuchang Shipyard in Wuhan, China. China has indirectly confirmed that it was testing what would be the world’s first warship-mounted railgun, a powerful electromagnetic weapon.SOCIAL MEDIA

A railgun is a weapon that abandons traditional gunpowder-based artillery for an electromagnetic charge capable of launching a projectile at devastating speeds and with deadly penetration. It creates a powerful electromagnetic field by supplying two conductive rails with an electric charge. When the projectile is placed in between, a physics phenomenon known as “the Lorentz force” blasts the object out at supersonic, or even hypersonic, speeds.

The unique workings of such a weapon give it a distinctive look, one strikingly similar to that of a large new gun mounted on China’s Type 072III-class landing ship Haiyang Shan in images that surfaced online in January. Chinese military watchers were quick to identify what appeared to be railgun characteristics such as a short, stubby barrel and large containers ideal for housing the massive power station required to power the futuristic weapon.

Chinese military watcher and Twitter user @dafengcao, who found the images on Chinese social media website Weibo told Newsweek at the time that China was “still on the way to catch up to the Western countries, the railgun just embodied their great endeavor.” A high-profile, verified Weibo account identified as belonging to a retired Chinese navy officer confirmed these findings.

Despite the online buzz, Chinese state media remained quiet—until now. Such a weapon would embody Chinese President Xi Jinping’s campaign to enhance and modernize his country’s armed forces, challenging even the U.S.’s technological lead. The U.S. Navy has tested its own land-launched railgun since 2008 but has so far been unable to develop a seaborne variant of the costly project. The current weapon can launch projectiles at over 4,500 miles per hour.

As The National Interest noted last month, however, the Navy has not yet abandoned its project, and China’s alleged innovation may only inspire the U.S. further.

Russia too has been working on its own railgun. In July 2016, scientists of the United Institute of High Temperatures at the Russian Academy of Sciences developed their country’s first electromagnetic railgun, according to the state-run Tass Russian News Agency. Like his Chinese counterpart, Russian President Vladimir Putin has also eyed a military buildup and unveiled a number of advanced weapons in a fiery State of the Nation address earlier this month.
