BLADE OF SUPER CAVITATING SCREW PROPELLER

摘要

FIELD: transport.SUBSTANCE: invention relates to ship building, namely, to blades of super cavitating propeller screws. Proposed blade features wedge-like profile of cross-section with concave driving surface and straight drag surface. Said profile makes only half of the blade while outside its medial section is represents the mirror image of the profile first half along perpendicular to cross-section chord with its turn through 180 degrees along blade cross-section chord axis.EFFECT: two-way rotation of screw propeller for lateral thrusting propeller driven by high-rpm motor.1 dwg
