Abstract

En strømningsstyrende anordning for en gassturbinmotor er vist som omfatter: en skovl som har en forkant, en bakkant, en sugeside og en trykkside; en vegg som støter mot skovlen; og en overgang mellom skovlen og veggen. Overgangen har et forstørret område ved forkanten langs suge- og trykksidene og mot bakkanten. I tillegg til å fjerne hesteskovorteks reduserer anordningen også varmelasten på skovlen ved å rette kaldere gass fra den proksimale enden av skovlen til den varmere gassen ved midtområdet av skovlen.
