Abstract
A cowl comprising, inter alia, a stationary part formed by a diffuser (10) which exhibits a fastening base (11), a nozzle-funnel (12), a connection zone (13), a cylindrical skirt (14), and a moving part (20) able to rotate about an axis (200), which moving part (21) exhibits a peripheral profiled annular hoop (20) which is intended to be rigidly connected to the blade (22) tips (221) of a helix and which is mounted coaxially in this skirt (14) so as to be able to rotate therein, is characterised in that, taking as references the direction of flow and the axis (200), this hoop (21) is delimited by an inner wall (2101), an outer wall (2102) and a rear section (2103), this connection zone (13) is delimited in particular by an inner surface (131) with an upstream limit (1310), and in that this rear section (2103) of the hoop (21) is situated in a plane (P) which is perpendicular to the axis (200) and which passes practically through the upstream limit (1310) of the inner surface (131) of the connection zone (13).
