Abstract

A rotor locking mechanism fits in a rotor's axial direction between first (7) and second (7') rotating blades. First (4) and second (4') locking halves each fasten on both adjacent rotating blades with first (8), second (8'), third (9) and fourth (9') clips in the rotor's axial direction.
