What principle does the delta 3 hinge use?
- Triangular pitch lever.
- Flapping actuators.
- Offset hinges.
Explanation
The delta-three hinge skews or offsets the flapping hinge axis so that blade flapping is mechanically coupled to a change in blade pitch. This pitch-flap coupling, achieved through the offset hinge geometry, reduces flapping and helps stabilise the rotor.

delta 3 hinge is used on elicopters to compensate asymmetry in lift. it allows the rotor to flap.
