摘要： An assembly (20) is provided for a gas turbine engine (136). This engine assembly (20) includes a gas turbine engine case (30), a conduit (24) and a bushing (26). The gas turbine engine case (30) includes a case wall (36) and a boss (38) at a port (66) through the case wall (36). The conduit (24) extends longitudinally along a centerline (60) through the port (66) and into an interior of the gas turbine engine case (30). The bushing (26) circumscribes the conduit (24) and is arranged within the port (66). The bushing (26) is engaged with and laterally between the conduit (24) and the boss (38). The bushing (26) is configured from or otherwise includes a cellular material (120). The cellular material (120) may be or otherwise include a cellular metal material and/or a cellular composite material.

摘要： A gas turbine rotor cover (10) is described, comprising a body (20), the body comprising an inner side (22) facing towards a central axis (50) and an outer side (24) facing away from the central axis, wherein the gas turbine rotor cover is configured and arranged to extend in an axial direction (52) and a circumferential direction (54) relative to the central axis. An inner layer of insulation (30) is attached to the inner side of the body and extends along at least part of the length of the body in the axial direction and/or an outer layer of insulation (40) is attached to the outer side of the body, and extends along at least part of the length of the body in the axial direction. A gas turbine (60) containing the gas turbine rotor cover (10) is also described.

摘要： A mid-turbine frame (MTF) system for a gas turbine engine is disclosed. The MTF includes an inner case, an outer case and a fairing sandwiched between the inner and outer cases. The fairing includes an inner ring spaced apart from and coupled to an outer ring by a plurality of hollow struts. The hollow struts accommodate support rods that connect the inner case to the outer case. Further, the hollow struts act as turning vanes for turning the flow of gases passing from a high pressure turbine (HPT) to a low pressure turbine (LPT) for purposes of providing the correct incidence angle to the first vane of the LPT. The outer ring of the fairing includes a plurality of bosses which receive attachment pins that pass through the outer case for correctly locating the fairing with respect to the outer case and for permitting radial expansion in contraction of the fairing.

摘要： The invention relates to a device (100, 100', 100") for guiding a fibrous structure (18) onto an impregnation mandrel (16, 16', 16") of a winding machine (10), comprising: a first radial shim (102a) intended to be positioned facing a first flange (26a) of the impregnation mandrel (16, 16', 16"), a second radial shim (102b) intended to be positioned facing a second flange (26b) of the impregnation mandrel (16, 16', 16"), and a frame (104) for supporting the first (102a) and second (102b) shims, said frame (104) comprising means (106) for adjusting the position of the first (102a) and second (102b) shims, which can position the first shim (102a) and the second shim (102b) at a distance from the first (26a) and second (26b) flanges respectively of the impregnation mandrel (16, 16', 16"), such as to maintain a first portion (180a) of fibrous structure (18) that extends along the first flange (26a) and a second portion (180b) of fibrous structure (18) that extends along the second flange (26b) bearing against the respective flanges, without obstructing the rotation of the impregnation mandrel (16, 16', 16").
