Centrifugal force is caused by blade rotation. When a helicopter transitions from the ground to a hover, the increase in coning angle is easy to see. There are several flight conditions that effect the coning angle. Is flying helicopter hard?

In forward flight, the rotor disk is tilted forward, which also tilts the total lift-thrust force of the rotor disk forward. When the helicopter is banked, the rotor disk is ...
WebBlade Flapping in Forward Flight In the past, experimental investigations on multiple helicopter models was the main tool for studying complex flowfield around rotorcrafts and prediction of rotor dynamics [6, 7, 8] but was a very expensive ... WebWhile transitioning to forward flight at about 16–24 knots, the helicopter experiences effective translational lift (ETL). As mentioned earlier in the discussion on translational …
WebMay 12, 2005 · The actual coning angle will vary during flight of course due to changes in the GW and the varying loading on the disk. During forward flight, if the teetering hinge is not in the plane of the blade masses a 2/ oscillating dynamic load will be transferred to the mast. The Bell 47 hub had two hinges at 90-degrees to each other.
