One thing that comes to mind is if the rotors are better off without backing plates... like instead of the entire rotor being exposed, it would now only be fed air through the ducts. Is less air (but more focused) as efficient as more air all over the place?
The ducts should direct air towards the rotor hat which will increase flow through the vanes between the friction surfaces. So you get some heat dissipation on both sides of each surface which is one of the advantages of a rotor like ST's aero rotor vs a solid hunk of iron.
