20080253883CASING - Casings are utilized within gas turbine engines in order to provide both an environmental containment for the engine core as well as inhibit release of debris should engine components fragment and fail in service. Traditionally, casings have taken the form of a solid containment shield to prevent debris and object release on percussive impingement with the casing. Such an approach avoids the uncertainties with respect to flap rupture propagation of the casing in use. However such casings are relatively thick and therefore provided a severe weight penalty in aircraft. By providing a casing which has a relatively thinner containment shield and an additional, where required, catch layer rupture of the containment shield can be allowed whilst the catch layer prevents rupture propagation and therefore aperture development to a sufficient size to allow the debris to pass completely through the casing at all or with sufficient energy to cause damage.10-16-2008
