摘要

The cover (20) has openings (33) for receiving balancing screws, and a displacement unit i.e. fastening screw (42), for displacing a nose cone (21) relative to a rear ferrule (22). The displacement unit is adapted to change the cover between an assembled position in which the openings are inaccessible outside the cover, and a balancing position in which the openings are accessible from outside the cover. The openings are formed in an interior annular portion (27) of the cover, where the portion is centered on a longitudinal axis of the cover. An independent claim is also included for a method for balancing a turboshaft engine.
