Abstract (en)
An aerofoil for a gas turbine engine is presented. The aerofoil has a pressure side wall and a suction side wall that join each other at a leading edge and a trailing edge. The pressure side wall has a pressure side outer surface and a pressure side inner surface. The suction side wall has a suction side outer surface and a suction side inner surface. The pressure side inner surface and the suction side inner surface are opposing surfaces. Within the aerofoil, a cooling passage is arranged between the pressure side inner surface and the suction side inner surface. A plurality of pedestals extending longitudinally between the pressure side inner surface and the suction side inner surface are arranged within the cooling passage. The plurality of pedestals includes one or more pedestal having dimpled surface.
