Structural ring mechanism for containment housing of turbofan

摘要

A containment system for wide chord turbofan fan blades, the system having a containment housing which forms a nesting area to accommodate broken blades and blade parts. Connected to the containment housing and constituting a part of the nesting area are structural rings which are positioned so that centrifugal forces will direct the larger blade fragments to impact upon the structural rings causing the large blade fragments to break into smaller fragments which are then easily housed in the nesting area, thus reducing the required area of the nesting area and minimizing the weight of the containment system.
