Abstract
The paper describes results of propeller cavitation noise experiments in non-uniform wake fields. Two propellers different in design with respect to the dominant type of cavitation have been investigated. The experiments were carried out with a planing boat, designed for cavitation noise research. The boat operates on a lake under acoustical free field conditions. The objective of these tests is to disclose the influence of propeller design and wake fields upon cavition noise.
