1. A turbine engine airfoil structure comprising:
an airfoil adapted to be supported to extend across a gas passage for a hot working gas in a turbine engine, the airfoil including sidewalls comprising radially extending pressure and suction sides; a platform structure located at one end of the airfoil and positioned at a location forming a boundary of the gas passage, and including;
a platform member including a gas side surface extending generally perpendicular from the airfoil at a junction with the airfoil, and providing a structural connection to the airfoil; anda separately formed platform cover attached to the platform member at the gas side surface, the platform cover extending from a location radially displaced from the gas side surface and in contact with one of the sidewalls of the airfoil, and including an outer surface located for contact with the hot working gas passing through the gas passage, wherein an intersection between the platform cover and the airfoil includes a depressed trough and forms an acute angle between the outer surface of the platform cover and the sidewall of the airfoil. |
