ANALYSIS OF THE OPERATION OF TANDEM CONTRA-ROTATING PROPELLERS BASED ON THE VELOCITY FIELD CHARACTERISTICS

Based on model investigations of tandem contra-rotating propellers carried out in a cavitation tunnel at the Department of Ship Propellers, Institute of Fluid-Flow Machinery of the Polish Academy of Sciences, and on a theoretical analysis of the velocity field of the propellers, relations for parameters of both propellers of trandem contra-rotaing propellers and their effect on the propellers behavior have been presented in the report. Conclusions following the analysis are to serve as guidelines for working out a method of designing tandem contra-rotating propellers.
