Abstract: A gearbox mounting link between a gas turbine engine structure and a gearbox mounting location comprises two engine attachment brackets secured to an engine structure, and attachment plate rotatably attached between the engine attachment brackets, and a secondary retention sleeve and fastener. The attachment plate includes a fusibly separable section configured to attach to the gearbox, a static section, and a shear necks connecting the statis section to the fusibly separable section. The secondary retention sleeve is supported by and secured to the static section. The secondary retention fastener is supported by the secondary retention sleeve, and is disposed through an oversized fastener passage through the fusibly separable section, thereby loosely retaining the fusibly separable section in at least one of the two degrees of freedom in the event of a load sufficient to break the shear necks, separating the fusible separable section from the static section.

Abstract: The invention relates to a mechanical fuse intended to be rigidly mounted between a drive unit (8, 9), and a receiver unit (10), each rotating about the same axis (7) of rotation, said fuse comprising a body (13) extending in a longitudinal direction parallel to said axis (7) of rotation, once the fuse is mounted between said drive unit (8, 9) and receiver unit (10). The invention is characterized in that said body (13) comprises a plurality of longitudinal bars (14), each bar (14) being deformable by bending, such as to form a twist-breakable mechanical fuse.

Abstract: A mounting link between an engine and a gearbox comprises an engine attachment piece, a gearbox attachment piece, and primary and secondary retention fasteners. The engine attachment piece is rotatably secured to the engine, and the gearbox attachment piece is rotatably secured to the gearbox. The primary retention fastener rigidly constrains the gearbox attachment piece with respect to the engine attachment piece in a single degree of freedom, but is configured to shear at a breakpoint load. The secondary retention fastener constrains the gearbox attachment piece loosely with respect to the engine attachment piece, and can withstand the breakpoint load. The gearbox attachment piece and engine attachment piece abut in a friction fit that provides Coulomb damping.

Abstract: A gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a fan and a braking system. The braking system is configured to selectively engage the fan during ground windmilling to apply a first level of braking to slow rotation of the fan. Further, when the rotation of the fan sufficiently slows, the braking system is further configured to apply a second level of braking more restrictive than the first level of braking.

Abstract: A method for compression of an incoming feed air stream using at least two variable speed compressor drive assemblies controlled in tandem is provided. The first variable speed driver assembly drives at least one compression stage in the lower pressure compressor unit driven while the second variable speed driver assembly drives higher pressure compression stage disposed either in the common air compression train or the split functional compression train of the air separation plant. The first and second variable speed driver assemblies are preferably high speed, variable speed electric motor assemblies each having a motor body, a motor housing, and a motor shaft with one or more impellers directly and rigidly coupled to the motor shaft via a sacrificial rigid shaft coupling.
