Abstract

An aircraft engine (10), has: an upstream stator (30) having upstream stator vanes (31) circumferentially distributed about a central axis (11); and a downstream stator (40) having downstream stator vanes (41) circumferentially distributed about the central axis (11), the downstream stator (40) located downstream of the upstream stator (30) relative to an airflow flowing within a core gaspath (24) of the aircraft engine (10), a number of the upstream stator vanes (31) being different than a number of the downstream stator vanes (41), major portions of leading edges (41A) of the downstream stator vanes (41) circumferentially overlapped by the upstream stator vanes (31), the downstream stator vanes (41) including: a first pair (44) of circumferentially adjacent vanes of the downstream stator vanes (41) spaced apart by a first pitch (P1), and a second pair (45) of circumferentially adjacent vanes of the downstream stator vanes (41) spaced apart by a second pitch (P2) different than the first pitch (P1).
