Abstract: A thermoelectric generator for a turbine engine is provided. The turbine engine can include a core having a casing surrounded by an engine cowl. The thermoelectric generator is attached to or formed integrally with the casing. The thermoelectric generator includes a power generation module formed by a plurality of thermocouples that utilize a temperature differential between a hot side and a cold side of the casing to generate electrical power. In one aspect, an electrically insulative layer is positioned between the casing and the power generation module. In another aspect, the thermoelectric generator includes a phase change material pack that includes an inner layer and an outer layer, the power generation module being positioned between the inner layer and the outer layer. In other aspects, the thermoelectric generator can be additively manufactured on the casing or another structural component of the turbine engine.

Abstract: Bleed air system includes bleed port with annular bleed slot in a compressor inner casing surrounding flowpath circumscribing a centerline in compressor inner casing. Inner and outer slot walls bound bleed flow passage through the bleed slot. Annular array of arcuate shields radially inwardly bound the bleed flow passage downstream and aft of inner slot wall. Each shield includes integrally-formed axially forward retaining portion, downstream portion, and upstream portion therebetween. Clipping means clips retaining portion to aft facing radial wall of annular lip on inner slot wall. Clipping means may be arcuate or annular clip having forward annular portion attached to annular aft flange substantially perpendicular to the centerline and forward annular portion disposed in annular slot extending into inner slot wall. Forward annular portion and annular slot may be cylindrical or conical. Clip may include aft conical portion radially offset from forward conical portion and transition portion therebetween.
