More Information
Summary:A gas turbine engine (20) includes an annular structure (210) disposed around an engine central longitudinal axis (A-A') of the gas turbine engine (20). The annular structure (210) defines an annular channel (212) and comprises a first density. The gas turbine engine (20) further includes a weight-saving filler (220) disposed within the annular channel (212). The weight-saving filler (220) has a second density that is less than the first density. The gas turbine engine (20) further includes an annular retention strap (230) disposed around the engine central longitudinal axis (A-A') of the gas turbine engine (20). The annular retention strap (230) is at least partially embedded in the weight-saving filler (220).
