METHOD OF PRODUCING SUSPENSION FOR A STRUCTURE IN A TURBOJET ENGINE USING A HYPERSTATIC TRELLIS WITH PRE-STRESSED LINK ELEMENTS

摘要

The invention relates to a method of manufacturing an assembly comprising a first structure (23), arranged to be rigidly connected to a housing of a turbojet engine, a second annular structure (21) surrounding the first structure, and a hyperstatic trellis of connecting rods (40a, 40b, 40c, 40d, 40e, 40f) maintaining the first structure (23) relative to the second (21), said method comprising a step of mounting said connecting rods of the hyperstatic trellis between said structures and being characterised in that it comprises a step for pre-stressing at least one of said connecting rods (40) to a pre-determined level, carried out before the mounting thereof between said structures. It also relates to a device which is suitable for mounting the pre-stressed connecting rods.
