Abstract: A turbomachine comprising a diffuser—distributor assembly comprising a downstream end-piece connected at its downstream end to means for injecting air for ventilating a turbine and delimiting with the impeller of a centrifugal compressor an annular cavity for the circulation of ventilation air taken from the outlet of the compressor, this turbomachine comprising means for taking air from the injection means and means for guiding this air to the radially internal portion of the downstream face of the impeller.

Abstract: A turbomachine front portion includes an internal support shroud for the fan outlet guide vanes, and a flow splitter fairing from which a primary duct and a secondary duct originate. The front portion includes at least one deflector system configured to prevent/limit the ingress of hailstones inside the primary duct, the system including at least one deflecting surface together with an actuator for moving the surface from a retracted position to a deployed position for deflecting the hailstones, the system being mounted on the shroud such that, in the deployed position, a downstream end of the surface is situated upstream of the splitter fairing.

Abstract: The present invention relates to a turbomachine front portion (1) comprising an internal support shroud (10) for the fan outlet guide vanes (12), and a flow splitter fairing (14) from which a primary duct (16) and a secondary duct (18) originate. According to the invention, said front portion comprises at least one deflector system (30) intended to prevent/limit the ingress of hailstones inside said primary duct, the system (30) comprising at least one deflecting surface (32) together with an actuator (34) for moving the surface (32) from a retracted position to a deployed position for deflecting the hailstones, the system (30) being mounted on the shroud (10) such that, in the deployed position, a downstream end (62) of the surface (32) is situated upstream of the splitter fairing (14).
