Hi everybody,
I hope there is no thread on this topic already, I did a search before but didn't find anything.
I lately just stumbled upon the open fan technology being developed by Boeing and Rolls-Royce.
Aerospace Firms Investigate Open-Fan Propulsion Technology | Defense Technology News at DefenseTalk
The benefits seem to be a huge increase in fuel efficiency but there doesn't seem to be very much information on this and I didn't find an answer to a few questions I have:
1. Does the open fan need a turbine directly attatched to it to work efficiently or would it also be suited to use it with a turboshaft setup or even a rotary engine?
2. I think the open fan would only be useful for high speeds and not so much for small airplanes flying at slower speeds (~200mph)?
Or would there be a way of adapting this to an airplane of this size?
3. I might be totally wrong here but the fan design somewhat reminds me of the P-51D. I'm aware that the double-rotor was used to balance the torque, but are there any other benefits to this?
Thanks in advance!
