Abstract:
PROBLEM TO BE SOLVED: To provide a turbofan engine formed by improving a reduction in engine efficiency due to a gap between a fan tip and a fan case.SOLUTION: A turbofan engine has a fan having a circumferential array of fan blades. A fan case encircles the fan. The turbofan engine includes at least one compressor section, a combustor, and at least one turbine section. The fan case comprises a composite structural member and a metallic member encircled by the composite structural member. The metallic member is mounted on the composite structural member to permit differential thermal expansion proximate the blades.
Abstract:
PROBLEM TO BE SOLVED: To provide a turbofan engine fan case cartridge, in which reduction of engine efficiency accompanying a gap between a distal end part of a fan and a fan case is improved.SOLUTION: A turbofan engine fan case cartridge comprising a metallic member is included. A first honeycomb has an inner diameter (ID) liner and is encircled by a front part of the metallic member. A second honeycomb is encircled by a metallic member at the back of the first honeycomb. A wear strip is encircled by the second honeycomb.
Abstract:
PROBLEM TO BE SOLVED: To provide a turbine engine fan case assembly.SOLUTION: A turbine engine fan case assembly includes a structural case and a liner assembly. A radially adapted mounting mechanism connects the liner assembly to the structural case. The mounting mechanism includes a circumferentially-distributed plurality of longitudinally elongated and radially outwardly open channels mounted to the liner assembly. The mounting mechanism further includes an associated plurality of inwardly-projecting projecting edge parts mounted to the structural case. Each of the projecting edge parts is accommodated in a corresponding channel, respectively.
Abstract:
A turbine engine fan case (48) comprises a composite body member (300) circumscribing an axis (500) and having an annular mounting portion (310, 410), a segmented polymer member (320, 330, 420, 440) along the annular mounting portion, and integrated therewith.
Abstract:
