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.
