Outer casing for a turbomachine fan conduit

摘要

The engine (10) has an external cylindrical cover (20) i.e. outer fan duct, mounted in downstream of an intermediate hood (16) and externally defining an annular space discharging a flow around the engine. The cover has a trellis framework (30) and detachable shielding plates (32) that are fixed at the framework. The framework has an upstream annular fixation plate (34) and a downstream annular connection plate (36) that are connected with each other by inclined and longitudinal rigid beams (42, 46). The rigid beam (42) is inclined with respect to axis (44).
