Engine rotation
Question for the engineers amongst you.
Right.
1) RR rotate clockwise, everyone else (GE, P&W) does the opposite, i.e. anticlockwise. Is there any reason why?
2) Finally, if I was able to take an engine and take all the blades out (compressor & turbine etc), rotate them (90 deg?) so the engine would have to turn in the opposite direction, would it make any difference (obviously ignoring the effects of where gearboxes and the likes are located and airflow disturbance etc.)
TIA, w.
