Abstract:In order to solve the matching problem between the propeller and the marine main engine in the operating condition of the ship，the paper combines the relevant ship mooring and navigation test standards, analyzes and summarizes the ship′s operational data, and combines the actual ship test with the theoretical calculation of the ship′s paddle matching. After research and analysis, the quantitative requirements for the outer characteristics of the fixedpropellers of the ship and the tugboat under common working conditions and special working conditions are obtained，which provides reference for the optimization and development of marine mainframes for different market segments.
Keywords:fixed pitch propeller; marine engine; external characteristic
