FIELD: shipbuilding; construction of propellers.
SUBSTANCE: propeller has hollow body of hub, many blades and many fasteners for each blade. Each fastener includes tension rod and flange member mounted on tension rod. Propeller blades may be of variable-incidence type for control of incidence and may be fixed in selected position by means of fasteners. Flange member has many slots and tension devices received by these slots. Tension devices may be extended from flange member towards wall of hub body, thus applying tension to tension rod.
EFFECT: enhanced strength of attachment of propeller blades in selected position.
