Abstract

A method for controlling the positioning of at least one rotor disc (2) about a tie-rod (3) of a partially assembled rotor (1) of a gas turbine comprises:• positioning the tie-rod (3) so as its longitudinal axis (A) extends substantially vertically;• detecting the eccentricity of the rotor disc (2) with respect to the longitudinal axis (A) of the tie-rod by means of an assembly (23) comprising a main device (24) coupled to a free face (13a) of the rotor disc (2) and at least one first reference device (25, 26) coupled to the tie-rod (3); the assembly (23) further comprising at least three lasers emitters (28) coupled to one between the main device (24) and the at least one first reference device (25, 26) and at least three respective photosensitive sensors (30) coupled to the other between the main device (24) and the at least one first reference device (25, 26); the photosensitive sensors (30) being arranged so as to intercept laser beams (B) emitted by respective lasers emitters (28).
