Postswirl Propulsors - A Design Method and an Application.

Abstract

A design method for postswirl (PS) propulsors is addressed. The principles of momentum, mass, and circulation conservation are satisfied and the effects of the hub boundaries have been taken into account in the design and analysis methods. A PS propulsor was designed for close-to-uniform flow at the operating point for a surface ship. Self-propulsion experimental results show that the performance predictions agree well with the measurements. Postswirl propulsors, mass conservation, momentum conservation, circulation conservation, hub effects.
