Low-pressure turbine assembling method for twin spool turbojet, involves mounting turbine module on casing of turbine in downstream from blades, and axially mounting blade of mobile wheel on downstream disk of turbine module

摘要

The method involves mounting a set of fixed blades of a distributor on an outer casing (16) of a low-pressure turbine. A blade (200-2) of a mobile wheel of the turbine is axially mounted on a downstream disk (304) of a pre-assembled turbine module. An upstream disk (402) and a downstream disk (404) of another pre-assembled turbine module are bonded together to form an integral assembly. The latter module is axially mounted on the casing in downstream from another set of fixed blades (100-3). Another blade (200-4) of the wheel is axially mounted on the downstream disk of the latter module.
