Geometry features and performance characteristics of an inland marine propeller

Abstract

Review performance characteristics of a marine propeller should be based on its geometric properties and the design standard of marine propeller. Based on an inland ship propeller which is currently widely used in the Ho Chi Minh city, the article provides a method of building a 3D model of this propeller from its coordinate data points obtained by a laser scanning devices. Then surveying the geometric characteristics of the marine propeller through 3D scanning, and making comparisons with the marine propeller manufacturing standards in the world in order to estimate the operating characteristics of this marine propeller. The analysis results obtained in the article can be used as a reference value for the simulation results of the characteristics of this insland marine propeller, as well as the experimental results on a miniature model of this propeller
