Interesting that this technology is having significant R&D budget poured in now. That means that there must be an intended introduction date for production Sikorsky machines.
The benefits to the helicopter industry will be significant. If nothing else then it means that vibration will be removed at source (by correctly terminating/damping the free end of the blades). If the system can be signed off as sufficiently reliable to perform all of the fatigue assesment against then TBOs may well go up. At the extreme payloads for a given rotor/machine size may well go up too.
So ultimately a little investment for a big return...
