Abstract
A blade containment system and method for use in a gas turbine engine having a plurality of blades mounted on a rotatable disk. The system comprises an annular casing in surrounding relationship with the blades and a plurality of panels, each having an interior noise absorbing structure and an outer containment structure, disposed about an interior surface of the casing so as to position the panels outward and forward of the blades. The panels are supported so as to fix the panels with respect to the casing during normal engine operation and to allow an impacted one of the panels to slide circumferentially when acted upon by a predetermined blade force caused by a released portion of one of the blades impacting the panel. Ramps formed in each end of the containment structure of each panel allow the impacted panel to slidingly engage at least a circumferentially adjacent one of the panels when acted upon by the predetermined blade force.
