ABSTRACT:
An aerofoil blade containment structure that is adapted to surround the low pressure turbine casing of a gas turbine engine includes an annular support member upon which is mounted a glass fiber knitted sleeve. The knitted sleeve is folded to define a plurality of interconnected secondary sleeves that are arranged in coaxial superposed relationship. Use of the containment structure obviates the use of thick, and therefore undesirably heavy, turbine casings.
