Zusammenfassung:A rotor wheel assembly 14, 10 comprises a rotor wheel 10 having a plurality of circumferentially spaced, female dovetail slots 12 and a plurality of buckets 14 having a corresponding male dovetail member 16. Each slot 12 further comprises a recess 42, which receives a corresponding key projection 40 disposed upon the male dovetail member 16. There may be a very small clearance between the key projection 40 and recess 42 in use. The walls 46 of the recess 42 may comprise flat parallel surfaces, as may the corresponding male key projection 40. The key projection and recess arrangement 40, 42 may prevent twisting or undue torque of the bucket 14 in use.
