Abstract
Aerial vehicles may be equipped with propellers having pivotable blades that are configured to rotate when the propellers are not rotating under power. A pivotable blade may rotate about an axis of a propeller with respect to a hub until the pivotable blade is coaligned with a fixed blade. When the propeller is rotating a lifting force from the blade may cause the blade to rotate to a deployed position that is not coaligned with the fixed blade.
