<p>5A method of measuring flow sections (Sloon, Siwn, Sioon) of a turbomachine nozzle sector (100) relative to two reference vanes (220, 310), wherein:a three-dimensional numerical model of the sector 10 is produced by digitizing;numerical models are provided for the two reference vanes;the reference vanes are reset at the ends of the numerical model of the sector in their assembly relative 15 positions in the nozzle; andthe flow sections (Sumn, Sumn, SI") of the sector are determined from sections of the numerical models of the sector and of the reference vanes;the nozzle sector having contact surfaces (131, 132,20 141, 142), and being positioned relative to adjacent nozzle sectors (200, 300) by putting said contact surfaces into abutment, the numerical models of the sector and of the reference vanes including models of thecontact surfaces involved in putting them into their25 assembly relative position, and step c) being performedby putting the contact surfaces into correspondence.Fig. 1</p> |
