EXPERIMENTAL INVESTIGATION INTO CONTRA-ROTATING PROPELLERS - PART 1

Y Kokubo, Yoshitaka Ukon

Abstract

A contra-rotating propeller is one of the most energy saving propulsor. In this paper, extensive experiments were performed to confirm a new design program code developed by the authors and to evaluate the reliability of measurements from two types of contra-rotating propeller dynamometers of different capacities. Reasonable agreement between the respective measurements were obtained and confirmed that the existing method was suitable for the design of contra-rotating propellers for higher speed ships.
