1. A core nozzle for a gas turbine engine, comprising:
- a core nozzle wall defining a core through which a core stream flows; and
a cowling assembly coupled to the core nozzle wall, wherein the core nozzle wall and the cowling assembly define a plenum to receive a portion of the core stream flow from the core nozzle; and
a thermoelectric generator assembly positioned in the plenum.

Abstract
In one embodiment, a gas turbine engine assembly comprises an engine assembly disposed about a longitudinal axis, a core nozzle positioned adjacent the engine assembly to direct a core flow generated by the engine assembly, a fan nozzle surrounding at least a portion of the core nozzle to direct a fan flow, wherein the core nozzle defines a plenum to receive a portion of the core stream flow from the core nozzle and a thermoelectric generator assembly positioned in the plenum. Other embodiments may be described.
