<p>The method involves producing a three-dimensional numerical model of a turbomachine nozzle sector (100) by digitizing using a contact-less optical measurement unit, and providing numerical models e.g. theoretical numerical models, for two standard reference vanes. The models of the vanes are reset at ends of the numerical model of the sector in an assembly relative position in a nozzle, and flow sections of the sector are determined from sections of the numerical models of the sector and the reference vanes. An independent claim is also included for a method for selecting a sector arrangement for a nozzle of a turbomachine.</p> |
