heal.abstract	The theoretical shortcomings of Lerbs' equivalent profile method are discussed and a novel equivalent profile method, using lifting-line theory, is presented. Details of the iteration scheme necessary for the solution of the resulting nonlinear problem are given. The problem of the equivalent radius is rotationally formulated and uncertainties are shown to exist concerning the choice of the equivalent radius and the approximate relations for the efficiency and the power loading coefficient. The test results of five model propellers, with different geometric characteristics, are used in an extensive sensitivity-analysis procedure to demonstrate the good behavior of the proposed lifting-line equivalent profile method.	en
