Vane-Wheel Propulsor for a Naval Auxiliary.

摘要

A design methodology for vane-wheel propulsors has been developed using three fundamental principles. Momentum conservation requires the net force generated by the vane-wheel propulsor to be balanced by the bare body drag and the drag due to propeller and hull interactions. Mass conservation determines the distribution of the vane-wheel circulation once the rotor circulation distribution is specified. Circulation conservation determines the magnitude of the circulation distribution to ensure zero torque on the vane wheel. A vane-heel propulsor has been designed for uniform flow at the operating point of the propulsor on the naval auxiliary AO-177 JUMBO.
