Turbomachine stator segment assembly

摘要

The assembly system for distributor sectors (20) to a gas turbine housing uses a movable flange (30) with a hook (32) fitted between collars (22, 23) on the sectors. The flange and housing have flat faces (31) positioned against one another in an axial direction, and the fixings are in the form of studs (37) that pass radially through the housing and hold the flange against the housing. The hook has a conical outer surface, at least in a central section passing under the curved edge of a collar.
