I thought it was using super capacitor, not fly wheel like US.

Apparently that hasn't been the case since the very beginning...

I am very surprised that many posts here saying that CV-18 uses supercapacitor as energy storage system. So I searched around and find that this notion is popular by many internet posters after CV-18's cat test.

The fact is that we only have official paper by Ma Weiming stating that his EM cat chooses flywheel. There is nothing else. So the notion of supercapacitor is for the moment baseless.

Members here should avoid spreading it without any new evidence to keep the standard of this forum high. At least people should put the notion as a question in the forum instead of taking it as a fact.
And
Maybe this is the table, it is from Ma Weiming's paper from 2016. I marked them in color, Orange: forbiding factors. Green: desirable. Blue: acceptable. It is clear that supercapacitor in the 2016s are not suitable for EM cat due to its low reliability, frequent need to replace and repair, short life. Some of the factors are unlikely going to improve over time because they are inheret disadvantages of supercapacitor (chemical degradation).

The "new" idea is to replace the linear motor driven launch track with a pulling cable winded around an rotating motor. The energy storage remains flywheel. Super capacitor today is far from capable in energy density for this application, and probably will remain so for a long long time.

The idea is not exactly new. There has been patent from Harbin Institute of Technology in 2016 applying this idea on arresting gear which is just the reverse of launcher. However I must give the credit to this paper as the first that we know of in exploring the idea in launcher application. The advantage is that the track is almost fully mechanical and much smaller in volume and weight and simpler, provided if it does not increase the size of the rest.
