Abstract: A rotary machine includes a rotary component disposed to rotate with respect to a stationary component. A foil bearing is disposed between the stationary component and the rotary component and configured to rotatably support the rotary component. A fiber optic sensing system including one or more fiber optic sensors is disposed in the foil bearing and configured to detect one or more parameters related to the foil bearing.

Abstract: A retainer for non-rotatably retaining a conduit member that extends through an opening in a casing wall. The retainer has an annular top wall that includes an inner periphery having inwardly extending projections to engage the outer surface of the conduit member. Additionally, the retainer includes a depending skirt that extends from the outer periphery of the top wall. A pair of outwardly extending straps extend from the skirt and include bolt holes for enabling the retainer to be bolted relative to the casing wall. The retainer limits axial outward movement of the conduit member and also diffuses and deflects any leakage air that passes around the conduit member to avoid impingement of the leakage air against the structural components and accessories that are positioned outside the engine casing.

Abstract: A coupling assembly includes a first coupling member, a second coupling member, and a coupling nut disposed over a portion of the second coupling member and threadingly engaging the first coupling member to retain the first and second coupling members together. An insulation blanket encloses the coupling nut, and a retention strip having a first end attached to an inner surface of the insulation blanket and a second end attached to the coupling nut is provided to prevent loosening of the coupling nut.

Abstract: A flow restrictor includes a body which permits the flow restrictor to be self-retained within a bleed port. Bleed ports are located over various portions of a gas turbine engine and extend through an engine casing. The flow restrictor body includes a bore extends between a flow restrictor body first and second ends. A slot extends between the first and second ends of the flow restrictor body. The slot further extends from an outer surface of the flow restrictor body to the bore. During assembly, the slot permits the flow restrictor to expand and conforms against the bleed port.
