Abstract: A gas turbine engine includes a rotor section proximate to a combustor section, where the rotor section is subject to bowing effects due to thermal differences and heat transfer at engine shutdown. The gas turbine engine also includes a heat pipe system. The heat pipe system includes one or more heat pipes installed between an upper portion of the rotor section and a lower portion of the rotor section. The heat pipe system is operable to accept heat at a hot side of the heat pipe system at the upper portion, flow heat from the hot side to a cold side of the heat pipe system, and reject heat from the cold side of the heat pipe system at the lower portion to reduce a thermal differential between the upper portion and the lower portion at engine shutdown.

Abstract: A component includes a substrate formed from a metallic or ceramic material and a thermal barrier coating positioned on the substrate. The component also includes a ceramic reflective coating integral with the thermal barrier coating. The reflective coating includes an arrangement of features configured to reflect at a wavelength at which peak emission from a heat source occurs. A method of making a component includes positioning a thermal barrier coating on the component and determining a wavelength emitted from a heat source. The method of making a component also includes producing an arrangement of features using a metamaterial to form a reflective coating and integrating the reflective coating with the thermal barrier coating.
