摘要： An airfoil assembly includes a vane that includes an outer platform, an inner platform, and an airfoil. The outer platform defines an outer boundary of a gas path. The inner platform is spaced apart axially from the outer platform relative to an axis and defines an inner boundary of the gas path. The airfoil extends axially between and interconnects the outer platform and the inner platform. Force loads caused by gases interacting with the airfoil are configured to be transmitted from the airfoil assembly to a case arranged around the airfoil assembly.

摘要： According to one aspect, a method of releasing a fan blade for testing a turbofan engine includes arranging an external shaped charge about an airfoil and modifying the airfoil by extricating one or more portions of material from one or more sides of the airfoil. The method further includes detonating the external shaped charge such that the airfoil is released at a selected time.

摘要： A machine having a rotor that is radially bounded at least in part by a containment assembly. The containment assembly may comprise a casing and a containment liner. The casing may have a radially inner surface facing a rotor of the machine. The containment liner may be formed form a plurality of panels bonded to the radially inner surface of the casing. The panels may form joints between adjacent leading and trailing panels relative to the direction of rotation of said rotor. At least one joint includes a portion of a trailing panel positioned radially outboard of a portion of the leading upstream panel.

摘要： According to one aspect, a method of releasing a fan blade for testing a turbofan engine includes providing an internal passage with a constant arc through an airfoil arranged about a blisk such that the constant arc of the internal passage aligns with a contour of the blisk. The method further includes packing the internal passage with a charge, modifying the airfoil such that the airfoil is released from the blisk evenly along a chordwise length of the airfoil, and detonating the charge such that the airfoil is released from the blisk at a selected time.

摘要： A containment assembly for a machine having a rotor radially bounded at least in part by the containment assembly. The containment assembly may comprise and inner casing member formed from a composite material, a containment liner bonded to a radially inner surface of the inner casing member, an outer casing member formed from a composite material and positioned radially outward of the inner casing member, and a containment core embedded between the inner and outer casing members.
