I wouldn't read too much into that, the "conventional" blade that they use for comparison would be most unlikely to be used in any current helicopter -the comparison is not dissimilar to comparing the noise from an early 7.2K HD to an SSD because they have roughly similar capacities. Valid; but not really useful.

The Eurocopter blade is really only notable for containing an arch and electric tip actuation (and it's the arch that improves the vortex interaction). The forward swept tip is not uncommon and has been dealt with very conservatively on what EC are currently showing

Great now how about an anti-idiot Harley owner?

Sorry? I don't follow you. All I was trying to do was point out that the blade really isn't that special, and explain why that is the case.
