In one of the tests, the proved its mettle by firing off 120 rounds – or close to what some of the artillery in service today can do.
After the lightning and thunder subsided, the entire system remained intact, according to the researchers.
One of the main sticking points the US had with rail guns was that they could not work out how to build something that could fire repeatedly without breaking down.
Meanwhile the success of the Chinese team can be largely attributed to a sophisticated measurement and diagnostic system.
The system is capable of collecting and analysing data from more than 100,000 component points simultaneously. That is nearly 10 times the number of sensors on a modern aircraft.
Chinese researchers working on electromagnetic weapons figure they could use the tech to zip a train through a vacuum tube at 1,000km/h, faster than any plane.
It has to find problems quickly, too, and work out what is causing them. A lot can go wrong with a machine that is complex and works in extreme conditions. Even the best technicians need days to sort it out sometimes.
But this in China can cut that time down to milliseconds.
And it can make decisions on its own. If something is not too serious, like a piece of equipment getting a little too hot, it will keep going. But if there is trouble that could cause real damage, like something wrong with the thrust, it will not fire even if everything is loaded up.
Lu’s team said this clever system had saved the pricey weapon three times already. And with every little problem found and fixed, the electromagnetic gun works smoother. In the last 50 shots, there had not been a single glitch.
