SECTIONS DE COMPRESSEUR DE TURBINE À GAZ ET CONDUITS D'ADMISSION COMPRENANT DES TRAITEMENTS DE PAROI D'EXTRÉMITÉ DE DÉBRIS D'OBJETS ÉTRANGERS SOUPLES

摘要

A gas turbine engine (GTE) compressor section is provided having Soft Foreign Object debris (SFOD) endwall treatments (36), which reduce peak damage to GTE components in the event of SFOD ingestion. The GTE compressor section includes a compressor rotor and a compressor intake duct (33). The compressor intake duct includes an intake flow passage (42), which extends through compressor intake duct to the compressor rotor. A first duct endwall (34) extends around a centerline (44) of the flow passage to bound a peripheral portion of the intake flow passage. An SFOD endwall treatment (36) includes topological features (38) formed in or otherwise provided on the first duct endwall. The topological features of the SFOD endwall treatment are configured such that SFOD impacting the topological features is directed in a radially inward direction toward the flow passage centerline prior discharge of the SFOD from the intake flow passage and into the compressor rotor.
