ADV-
DISADV-
~3+ Blades

~Each blade can flap, feather, lead, lag independently

~Done through various hinges and dampers

ADV- Smooth ride, and lots of lift
DISADV- High maint. cost, storage, ground resonance
Semi-Rigid:
-

ADV
DISADV
~2 Blades

~Flap as a unit through a teetering hinge

~Feather through a feathering hinge

~Lead and lag forces minimized b/c the blades are underslung

ADV- low maintenance cost, storage space
DISADV- Low G/mast bumping, less lift, bumpy ride in turbulence
RIGID:
-
-
ADV
