Blade Geometry

Due to no design guidelines available for the hubless propeller，based on the relative inflow velocities together with blade root strength considerations, the Ka –series propeller’s blade geometry was re-designed with an inversion of the thickness distribution of the sections. Accordingly，the blade geometry model for hubless rim-driven propulsors was designed，then three types of hubless rim-driven propulsors’ models were established and calculated numerically. The results show that thrust coefficients and torque coefficients for hubless rim-driven propulsors are similar to the ducted Propeller’s. Due to no hub, with the new thruster the hub-vortex is avoided and the cavitation minimized.
