ROTOR BLADE AND GAS TURBINE EQUIPPED WITH SAME

摘要

Formed in this rotor blade (50) are blade airflow passages (71) which continuously extend inside a blade body (51) and a platform (61). Formed in the platform (61) are multiple ventral-side passages (72) which extend from the blade airflow passages (71) toward a ventral side in the circumferential direction, open at a ventral-side end face (64), and are arranged in an axial direction (Da). Also formed in the platform (61) are a dorsal-side main passage (73) for cooling air to flow therein and a dorsal-side passage (74) that connects to the dorsal-side main passage (73) and extends along a dorsal-side end face (65) from the dorsal-side main passage (73).
