FIELD: shipbuilding.
SUBSTANCE: invention relates to the field of shipbuilding, namely to marine propellers, and can be used as a propulsion device for vessels of various purposes. Assembly for connecting a composite blade to a metal propeller hub includes a metal hub, a pressure disk, a composite blade and fixing screws. Base of the composite blade has a section of a rectangular shape bent in a plane parallel to a median plane of the blade in a plane orthogonal to the plane of the blade and perpendicular to the axis along the blade. Base has a rectangular shape, while the edges of the base of the composite blade from the front and rear tips have an inclined step. Metal hub has a recess of a rectangular section and an inclined step corresponding to the base of the composite blade, the pressure plate contains a response inclined step corresponding to the metal hub and the base of the composite blade.
EFFECT: increase in the integrity and strength of the structure is achieved.
