TURBINE ROTOR BLADE AND ADDITIVELY MANUFACTURED TURBINE ROTOR BLADE

A turbine rotor blade (120) is additively manufactured and includes an airfoil body (122) with a radially extending chamber (134) for receiving a coolant (236) flow. A platform (150) (extends laterally outward relative to the airfoil body (122) and terminates at at least one slash face (230, 230PS,...

Beschreibung
Zusammenfassung:	A turbine rotor blade (120) is additively manufactured and includes an airfoil body (122) with a radially extending chamber (134) for receiving a coolant (236) flow. A platform (150) (extends laterally outward relative to the airfoil body (122) and terminates at at least one slash face (230, 230PS, 230SS). A cooling circuit (234) is within the platform (150) and is in fluid communication with a source of the coolant (236) flow. Cooling passage(s) (172, 240) are in the platform (150) and in fluid communication with the cooling circuit (234). The cooling passage(s) (172, 240) extend in a non-linear configuration from the cooling circuit (234) to exit through the at least one slash face (230, 230PS, 230SS) of the platform (150), providing improved cooling compared to linear cooling passages (172, 240).
