THE CAVITATION CHARACTERISTICS OF MAU TYPE PROPELLERS

The authors study the MAU type propellers with improved cavitation characteristics. The "Two-Dimensional Cavitation Bucket Chart" which was developed by Gutsche, Nakajima, Ito, etc. is insufficient for predicting the cavitation of propellers because the method is originally based on two-dimensional sections. The authors proposed a new chart, "Three-Dimensional Cavitation Bucket Chart" using Koyama's lifting surface theory of propellers and the concept of two-dimensional corresponding sections. Confirming the utility of the three-dimensional cavitation bucket chart theoretically and experimentally, the authors develoepd a new prototype propeller, which was named "KB type". The propeller series (KB type) was developed on the basis of the results of the MAU type propellers, and a noticeable improvement in cavitation characteristics was obtained without sacrificing the overall efficiency of MAU type propellers.
