Maximum speed
Hi,
I'd like to ask what happens as a helicopter approaches its maximum speed at level flight. What observations would we make if we increase the speed gradually towards maximum?
Specifically:
- Engine RPM
- Lift and drag forces acting on the main rotor blades
- Helicopter's attitude to maintain level flight ( How should pitch and roll change )
- Flight qualities (i.e does it tend to roll, pitch etc. )
- Vibrations and sounds
