Front part of a turbomachine comprising a system for deflecting foreign bodies, such as hailstones

摘要

The turbomachine (1) comprises a flow splitter fairing (14) from which a primary duct (16) and a secondary duct (18) originate. A deflector system (30) comprises an shape memory alloy made actuator (34) that moves a deflecting surface (32) from a retracted position to a deployed position for deflecting the hailstones inside the primary duct. The system is mounted on support shroud (10) for the fan outlet guide vanes (12) such that, in the deployed position, a downstream end of the surface is situated upstream of the splitter fairing.
