Main Rotor RPM
I have looked in many place and not found the answer to this question:-
Could a helicopter(any helicopter) benefit by having a higher RPM on its main rotor(plus ratio'd up for TR), or is the RPM controlled by Blade/head/design strength, I have a feeling that one or two answers may well point to things that we PPLs dont really know about, but if a blade cord was increased slightly, shortened the blade in length with the relative alterations to final drive gearing and bearings would this not allow a greater safety margin in lighter helicopters, with better flight/manouver responce .
This question has partly been egged on by the comments on the series called Dangerous flights(The ferrying of A/C around the world) the people there were given a twin F/W that had more powerful engines and different props(from original design), so if it works on a FW would it on Heli's.
