BEHELFSZUSAMMENBAUVORRICHTUNG FUER DIE EINSTELLUNG VON VERSTELLBAREN TURBOMASCHINENLEITSCHAUFELN.

摘要

A temporary locking system for the angular positioning of variable-pitch blades (4) of a turbo engine, which are driven by means of a control ring (10), comprises at least one captive bolt (12) driven in longitudinal translational movement by at least one of the screws (3) fastening the downstream shell (2) of the housing to the upstream shell (1), said bolt allowing the complete removal of the screw only in a position of the ring (10) in which the blades (4) have such an orientation that their leading edge (4d) is free of the zone of the upstream shell (1) of the housing. …The invention is used for the mounting/dismounting of the compressor housings of aircraft turbo engines. ……
