Heavy duty and high performance propeller, has hub and blades, where squamous formations are provided in wave form at rough surface of blades and abrasion-resistant rubber coating is applied to surface of blades

摘要

The propeller has a hub and blades (2), where squamous formations (3) are provided in wave form at a rough surface (4) of the blades and the water flows through the blades. The blades are made of metal, where an abrasion-resistant rubber coating is applied to the surface of the blades, and the scale-like formations are arranged on the rubber coating, which is roughened. The blades comprise a metal coating, and micro rubber profiles are arranged on the rubber coating.
