INSTRUMENTS FOR MEASURING PROPELLER THRUST OSCILLATIONS AND COMPARISON OF TEST DATA FOR TMB MODEL 4521 AND USS SURIBACHI (AE21)

Abstract:

Results are presented of model tests for evaluating instrumentation developed to predict propeller thrust oscillations produced by nonuniform wake, interference, and reflection. The model test results are compared with results of tests on USS SURIBACHI AE 21. No definite explanation was advanced for the difference between ship and model test results. Possible contributory causes of the difference are 1 shipboard measurements were made at the end of a long and elastically complicated propeller shaft, 2 scale effect of propeller wake between ship and model, and 3 instrumentation error.
