Abstract

Ce moteur est du type comportant un compresseur radial et une grille directrice axiale disposée devant la chambre de combustion, un palier principal du générateur de gaz étant alimenté à travers les aubages de la grille. Il est caractérisé en ce que la grille est divisée en groupe d'aubages comprenant de petits aubages et un grand aubage agencé sous forme d'aubage creux pour l'alimentation du palier, les conduits d'écoulement entre les aubages présentant de dimensions sensiblement identiques. L'invention est applicable aux moteurs à turbine à gaz comportant un compresseur radial.
