Abstract

La présente invention concerne un procédé de caractérisation des performances aérodynamiques d’aubes de stator (6) agencées en aval d’aubes d’une hélice de propulsion (4) d’un système propulsif (1) d’axe longitudinal (2), les aubes de stator recevant un écoulement d’air ayant une vitesse V12, qui est la vitesse de flux d'air sortant des aubes de l'hélice de propulsion, comportant une composante longitudinale Viz et une composante tangentielle associées à une vitesse de giration générée par l’hélice de propulsion, le procédé comprenant les étapes :a) calculer, pour un nombre de Mach donné à une vitesse de vol V0 donnée, des performances aérodynamiques des aubes de l’hélice de propulsion (4) comprenant un ratio d’avancement J1, un angle de calage ;b) calculer, pour un nombre de Mach donné à une vitesse de vol V0 donnée, un angle d’écoulement fonction du ratio d’avancement J1 pour une pluralité d’angle de calage . Figure à publier avec l’abrégé : Figure 7The present invention relates to a method for characterizing the aerodynamic performance of stator vanes (6) arranged downstream of the vanes of a propulsion propeller (4) of a propulsion system (1) of longitudinal axis (2), the stator blades receiving an air flow having a speed V12, which is the air flow speed exiting the blades of the propulsion propeller, comprising a longitudinal component Viz and a tangential component associated with a generated rate of gyration by the propulsion propeller, the method comprising the steps: a) calculating, for a given Mach number at a given flight speed V0, aerodynamic performance of the blades of the propulsion propeller (4) comprising a ratio of advancement J1, a pitch angle; b) calculating, for a given Mach number at a given flight speed V0, a flow angle as a function of the advancement ratio J1 for a plurality of pitch angles.
