AN INVESTIGATION OF THE EFFECT OF PROPELLER SECTION PARAMETERS ON HULL SURFACE PRESSURE FLUCTUATIONS
This paper presents a new approach to propeller and blade section design methods, based on which the effects of blade section parameters, such as camber and thickness distributions as well as maximum camber, on its hydrodynamic characteristics such as cavitation, lift and drag characteristics were studied. Then the effects of these parameters on hull surface pressure fluctuations were further investigated by means of numerical experiments and a new blade section form, which is the best from the point of view of hull surface pressure fluctuations, was found. The design methods were applied to a practical design example and cavitation tunnel experiments have been carried out to validate the proposed blade and propeller design methods.
