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

[clarkgap]

This thread is intended to collect all information about rthe developement of Chinese electromagnetic launcher (EML) from reliable sources (Journal, conference publication, lecture by real expert, scientific award .etc).

I realized that many members overestimate the technological level of Chinese EML, and some members underestimate that. I hope this thread can provide some reliable and objective information about Chinese EML.

303EMG: a railgun prototype tested in 1988. A 25 x 25 mm square bore railgun launched a 30.2g projectile at 3.2 km/s.
503 round bore railgun: A 25 mm diameter round bore railguns launched a 100g projectile at 3+ km/s.

The International Symposium on Electromagnetic Launch Technology (EML) is a great information sources.

Dr. Jun Li, president of Electromagnetic Launch Technology Committee of China’s Electrotechnical Society. He got the 2012 Peter Mark Medal for Outstanding Contribution to Electromagnetic Launch Technology for his work on a 10 MJ railgun prototype. The journal about design and testing the 10 MJ railgun was publicated on IEEE in 2011.

In 2017 18th EML, a Chinese journal told about a Modular Pulsed Alternator Power System for Driving a 32-MJ Railgun, which can 10.3 kg projectile to 2.5 km/s.

Westinghouse Electric Corp use EML launched a 100 g preojectile at 4.2 km/s in a demonstration experiment in 1982.
Maxwell Laboratories Inc conducted a railgun (CHECMATE) and launched 100-350 g projectiles at 1-3 km/s in 1986-88.
US DARPA tested two 90 mm railguns which could launched a projectile weighting several kilograms at 2-2.5 km/s in 1990s. The 9 MJ railgun at University of Texas at Austin (CEM-UT) launched a 2.44 kg projectile at 2.577 km/s in February 1990 (8.1 MJ), and a 4.49 kg projectile at 1.325 km/s in 1991 (3.9 MJ).

French-German Research Institute of Saint-Louis tested a 10-MJ railgun (Pegasus) with 40 mm square bore and 50 mm round bore in 1998. The railgun launched 300-650 g projectiles at 2.3-2.5 km/s in early experiment. Then it launched a 2 kg projectile at 2.1 km/s (9.45 MJ) in the later experiment.

LMAO as soon as India news picked up on an achievement our R&D did, you guys couldn't resist.

No. I just found some old thread about EML. Many member overestimated the technological level of China on that. I want to provide correct information.

I was thinking that an Indian will bring up the fact that it tested a rail gun the last couple of days. China achieved that in 1988. But of course, Indians will assert that you bring up this fact to embarrass them.

This is because to Indians, what China did in 1988 or any time in its history are all about Indians. US dealt more with Indians in our history. They are now mostly in reservations.

China and India are both developing countries. Our scientists doing great. But we has just overtake European in this field, still a long distance with US.

India achieved a prototype in 1986

 

[21stCentury]

India achieved a prototype in 1986

its 2017 now, where are the results of this Indian prototype over 3 decades ago?

 

[faithfulguy]

India achieved a prototype in 1986

So did India waited another 30+ years to come up with another prototype?

No wonder with LCA's long development time, it'd still a success by Indian standard.

 

[clarkgap]

India achieved a prototype in 1986

I think you are talking about the railgun that I posted on #2. However, I did not find the credible source about the date of the experiment. May you help me?

 

[lonelyman]

Please don't put India and China in the same sentence, we are way out of your league and frankly it's very embarrassing your media constantly compare china to India.

We don't want to be associated with India

I think he is more than likely referring to a failed prototype ...

Soon as Indian rail gun test news arrive, this thread was started. Typical inferiority complex of chinese.

These rail gun tests have been reported since 2012.

 

[clarkgap]

Soon as Indian rail gun test news arrive, this thread was started. Typical inferiority complex of chinese.

Process:
1. I found a thread about DRDO successfully tested a railgun prototype. I read it, think it is not bad, then leave it.
2. I found another thread about it in next day. There were some members saw the principle prototype as a military one. I told them there is still a long distance between this and a military railgun.
3. Some one asked me to provide reliable evidences to prove that many countries (include india) had done such experiment in last century.
4. I finally found the sources. During the look-up, I read some old thread about Chinese EML in Chinese defence forum. Then I realized that some members were influenced by the hyperbole from media and overestimate the technological level of Chinese EML.
5. I posted this thread in order to avoid these members make same mistake in further.

Soon as Indian rail gun test news arrive, this thread was started. Typical inferiority complex of chinese.

May be I posted too much link. The part about foreign EML development is bloked and awaiting moderator approval. So you cannot see it. I use this part to show that Chinese EML is not as good as the hyperbole.

Guys ... can we try to leave out India?

it is irrelevant.

The journal about design and testing the 10 MJ railgun was publicated on IEEE in 2011.

I'd like to ask if this is a 10MJ railgun or a 10MJ facility.

Dr. Li was responsible for designing the 10 MJ electromagnetic launch facility

The latter, given the implication of >30% efficiency, would make this a >3MJ Railgun.
