“…Based on the clarifications of the work of [1], which through an extensive and detailed review eliminated several doubts and obscure points, various information are correlated that culminate in the continuity and integration of several previous works. Among the main works evaluated for the formulation of this work consider [2], [3], [4] and [5]. Consequently, the objective and contribution of the present method was then to develop and validate a simplified and quick methodology for analyzing the efficiency of marine thrusters, since in previous works, validations and comparisons with numerical and empirical results were scarce and not detailed.…”

The analysis of marine thruster designs can use several methods, each of which has a different degree of complexity and computational effort, empirical models, blade element theory, vortex theory, airfoil, airfoil, panel method and computational fluid dynamics are some examples. The present work evaluates and reviews thruster design methods related to Theodorsen and Goldstein's Vortex theory, proposing a simplified and fast method both for calculating a known thruster and for generating optimized geometry. The influence of the Reynolds number on the hydrodynamic parameters in terms of lift and drag was considered and the Levenberg-Marquardt method was applied to solve the set of equations. Despite these methods being relatively known, there are few works that present applications of the method and analyzing the results with comparisons.
