Abstract
A deformable fastener assembly for use with a gas turbine engine. The deformable fastener may be used to fasten a component of the gas turbine that is subjected to high temperatures and thermal deformation, such as an impingement sleeve assembly, to a rigid portion, such as the inner turbine shell of the gas turbine engine. The deformable fastener assemblies may permit components to be fastened to a rigid portion of the gas turbine with a consistent load input to permit frictional transient sliding of the component relative to the rigid portion of the gas turbine engine.
Claims19
A fastening system configured to fasten a component subjected to thermal deformation to a rigid portion of a gas turbine, said fastening system comprising at least one fastener adapted to fasten said component to said rigid portion, said at least one fastener including a deformable member adapted to deflect in response to an axial force being applied to said at least one fastener.
An impingement sleeve assembly of a gas turbine engine comprising a plurality of impingement sleeve panels fastened to an inner turbine shell of the gas turbine engine with a plurality of deformable fasteners, said plurality of deformable fasteners each including a fastener having a deformable member positioned between a head of said fastener and a mounting flange of said plurality of impingement sleeve panels.
