Abstract

Un problème récurrent des moteurs à turbine à gaz est une lacune quant à la facilité et la rapidité d'entretien de certaines composantes de tels moteurs. L'architecture des moteurs peut être conçue pour faciliter l'accès aux composantes internes du moteur. Une telle architecture de moteur peut comprendre un support de corps central avant qui offre une paroi annulaire interne pour un chemin d'écoulement principal. Le support de corps central comprend des premières cannelures. Une architecture d'engrenages établit la connexion entre une bobine et un ventilateur pivotant autour d'un axe. Un support flexible établit la connexion entre l'architecture d'engrenages et le support de corps central. Le support flexible comprend des deuxièmes cannelures qui sont entremaillées avec les premières cannelures pour transférer le couple entre elles.
