Abstract: An example gas turbine engine includes a compressor including a casing defining a passageway and a shaft extending through the passageway. The shaft drivingly coupling the compressor and a turbine of the gas turbine engine. The shaft has an opening to receive airflow from the passageway. The gas turbine engine also includes an inner shroud, stator vanes coupled to and extending radially between the casing and the inner shroud, and an offtake scoop disposed on a downstream side of the inner shroud. The offtake scoop has a channel to direct the airflow radially inward toward the opening in the shaft.

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.
