The present invention relates to a method for modeling at least one portion of a blade (2) of a non-ducted propeller (1), wherein the blade portion (2) is offset (3). The method is characterized in that it comprises the implementation, by data processing means (11) of a device (10), of the steps of: (a) Parametrizing at least one auxiliary curve representing the value of a deformation parameter (x0, Ymax, dymax) according to a section height in the blade (2), wherein said parametrization is implemented according to at least one additional parameter, (b) Parametrizing a main curve representing a deformation of said blade (2) characterizing the offset (3), according to a position along a section at a given height in the blade (2), wherein said parametrization is implemented according to at least the deformation parameter (x0, ymax, dymax) and said section height in the blade (2), (c) Optimizing at least one of the additional parameters; (d) Plotting the values of the optimized parameters on one interface (13) of said device (10).
