Stiffener for the low pressure compressor of an aeroengine

摘要

The stiffener has two parts fixed to each other by screws/nuts with clinch. One end (22) of the stiffener has a fixing unit (24) connected to a casing (7) of an engine at the level of structural arm. Another end (32) of the stiffener has another fixing unit connected to a low pressure compressor (5) at the level of upstream side of a synchronizing ring. The stiffener is made up of aluminum. The sides are in the form of arc of circle and define a surface extracted from a frustum. Independent claims are also included for the following: (A) a method of increasing rigidity of an aircraft engine at the level of a low pressure compressor (B) utilization of a stiffener for compensating unbalancing effect in an aircraft engine.
