Abstract
A method of selecting an arrangement of sectors for a turbomachine nozzle is disclosed. The method includes: A) creating a database of three-dimensional numerical models of the sectors by digitizing; B) setting a criterion for selecting an arrangement of sectors and setting a desired value for said criterion, the criterion being a function of the shapes and the relative positions of the sectors; C) for the various arrangements that are evaluated, determining the relative positions of the sectors when assembled together by performing a virtual assembly, and as a function of said positions, determining the value of the selection criterion for the arrangement under evaluation; and D) retaining the arrangement for which the selection criterion has the value closest to the desired value.
