FIELD: shipbuilding.
SUBSTANCE: invention relates to shipbuilding, namely, to production of composite blades, which are part of propulsion device design. Propeller blades of composite material are made by hot pressing in metal dismountable form, in which prepreg layers are laid. Blades with glued butts of composite material are inserted from side of external radius into rotor, made also from composite material, and are glued.
EFFECT: required strength of propeller is achieved.
