<p>5A method of selecting an arrangement of sectors (100, 200, 300) for a turbomachine nozzle, the method comprising the following steps:creating a database of three-dimensional 10 numerical models of the sectors by digitizing;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;15 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 under20 evaluation; andD) retaining the arrangement for which the selectioncriterion has the value closest to the desired value.This method serves to optimize selecting sectors in a nozzle.25Fig. 1</p> |
