With upturned exhaust on H-60 rotor blades need to be positioned on centerline to avoid “charring” during rotor brake starts. I suppose even slowly rotating the pusher prop would help, but seems to be a recipe for disaster for personnel operating around the aircraft.
I’ve heard that the pusher on Raider X is electric driven, I assume clutching of the drive system would still be required?
I used to be pretty solid in the co-axial camp but the more I hear about the challenges associated with maturing the technology the less suitable it appears.
Would be interesting to see the engineering challenges both designs face discussed in detail by some of the members that have engineering backgrounds, think I’ll start a new thread on that in a bit.
