Marine propeller with blades with individually controllable pitch

摘要

The propeller has a hub portion (4) that is rotated about a rotation axis (X). Several blades (1-3) are connected to the hub portion pivotally such that rotation axis of hub is transverse to adjustment axes (X1-X3) of respective blades. An adjustment device (5) is arranged for adjusting pitch angles (W1-W3) of blades respectively. The adjustment device is designed such that blade pitch angles of respective blades are varied during rotation of the blades.
