Spinning Modes in Ducted Submersible Vehicle Propellers,

Abstract

The spinning mode theory, first developed in the study of jet engine compressor pure tone noise, is applied to the ducted marine propeller. Because of the lower number of blades and lower rotational speeds, the interaction noise generated in the marine situation can give rise to non-decaying spinning modes. A graphical procedure for predicting these non-decaying modes is developed and discussed. (Author)
