Abstract
A low pressure turbine shroud assembly includes a backsheet with enhanced blade containment capabilities that is sized to be retrofitted into a conventional low pressure turbine assembly. The backsheet has first and second mounting rails at axially opposite ends thereof and a blade containment sheet shield disposed therebetween. The rails and the containment shield are of a uniformly increased thickness as compared with a conventional backsheet rail and containment shield design. The assembly also includes a modified mounting hook for mounting the improved backsheet to a case extending around the shroud. The mounting hook is of reduced thickness as compared with a conventional mounting hook for a conventional backsheet proportional to the increase in thickness of the backsheet. The assembly also can include a rub strip disposed between a radially inner surface of the backsheet and a turbine blade.
