Hm.Found another patent 201610437492.X filed by Harbin Polytechnic University in the same year as the one above in post 3078. It is in Chinese, if you are interested you can get it from google patents.

This time, it is a linear motor and linear eddy current brake. It works in the same principle as above. The advantage that I can see are 1. Better heat depreciation because the conductor (where the eddy current is generated) stretched out through the length of the deck, and 2. No cable drum and cable routing mechanics. The drawback is that there can only be one launch track placed in the middle of the two arresting tracks on the angled deck, this however seems to fit all rumors of 002 have only one angled deck launch rail.
There is no photo evidence of this linear design being tested in full size so far.
How they can adjust the resistance ?
I mean, reliably .
