FIELD: shipbuilding.
SUBSTANCE: invention relates to the field of shipbuilding. The marine propeller consists of blades and a hub. The marine propeller is made of one-piece of a layered anisotropic polymer composite material and has closed cavities inside, filled with isotropic polymer material. The isotropic polymer material has a lower density in relation to the base material of the screw and is reinforced with short fibers.
EFFECT: improved performance is achieved.
