Method for loading and tangential locking of rotor blades and corresponding rotor blade

摘要

A method of loading and locking a plurality of tangential rotor blades (30) is provided. The method includes the steps of providing a disk (12) having a slot (52) and a pair of rails (58, 60) adjacent the slot (52), positioning a first snap seal (56) in a desired location over the slot (52) and the rails (58, 60), radially loading a first blade (30) having a platform (32) into the slot (52) and rotating the blade (30), and positioning the first blade (30) adjacent the snap seal (56) so that a portion of the snap seal (56) slides under the platform (32). The rotor blades (30) preferably have an attachment part (36) which comprises a circular neck (38) and a dovetail portion (40) having two ends (40, 46) and upper and lower chamfered edges (42) at each of the ends.
