摘要： A rotor assembly and a gas turbine (1000) including the same are proposed. The rotor assembly includes blade fastening assembly (2000) including a fastening key (2100) having a through hole (2111), a rotor disk (1120) including a disk slot (1321) into which a root member (1313) is inserted, the rotor disk (1120) having a first groove (2001) with a shape corresponding to a portion of the fastening key (2100), and a pin groove (2003) connected with the first groove (2001), a platform (1312) having a second groove (2002) formed in communication with the first groove (2001) and forming a shape corresponding to a remaining portion of the fastening key (2100) in a state of being inserted into the disk slot (1321), and a fastening pin (2200) inserted into the threaded hole (2111) and the pin groove (2003). Further a method for assembling the rotor assembly is proposed.
