Method for modelling a part, in particular a turbine blade

The present invention relates to a method for modelling a part (1), the method being characterised in that it comprises implementing, using data processing means (11) of a piece of equipment (10), steps of: (a) parameterising a curve of class C1 representing the value of a physical quantity characterising said part (1) as a function of a position along at least one portion of the part (1), the curve being defined by: a. two end points (PCU0, PCUK) defining the extent of said portion of the part (1); b. at least one intermediate point PCUi, i [[1,K - 1]]) located between the two end points (PCU0, PCUK); c. at least two Bezier curves connected to said intermediate point; the parameterisation being carried out using one or more parameters defining said intermediate point; (b) determining optimised values for said parameters of said curve; and (c) returning the determined values to an interface (13) of said piece of equipment (10).
