Paul,

Just for your info. This "harmonic drive" may be a candidate for a hight
ratio gear reduction unit needed for turbo compounding.
I have not looked at details regarding input speeds, reduction ratios,
overall size, weight and associated power it is capable of. Just a thought.

Interesting technology.  Might be just the ticket for my electric landing
gear retraction system.
Ratio is to high for turbo compounding however.

For an explanation on how it works look here.
