The structural member may be a casing for a rotary assembly e.g. a fan of a gas turbine engine. The main body may incorporate strengthening ribs and conduits and may have a random or graduated arrangement of different sized cells forming the cellular material. A recess may be defined on the radially inner face of the main body to receive an abradable material suitable for forming a seal with the blades of the fan.Field of SearchINCLUDING DESTRUCTIBLE, FUSIBLE, OR DEFORMABLE NON-REUSABLE PARTWITH SOUND OR VIBRATORY WAVE ABSORBING OR PREVENTING MEANS OR ARRANGEMENT Between blade edge and static part Erodable or permanently deformable Erodable or permanently deformable Specific casing or vane material Casing with axial flow runner Air and diverse fluid discharge from separate discharge outlets (e.g., fan jet, etc.) With safety device Removing mold by destruction By treating occluded solids By gas forming or expanding With destruction of pattern to disassociate Pattern making Coating or forming of object | |
