摘要
A gas turbine engine including a hybrid waveguide for placement adjacent a flow path for hot combustion gases in the engine is presented. The waveguide includes first and second opposing ends and a first section formed of a first material extending from a transition region to the first end and a second section formed of a second material extending from the transition region to the second end. The first material is a metal or a ceramic and the second material is an electrically isolating material having a lower thermal conductivity than the material of the first section. A membrane may be used to isolate a cavity of the waveguide from combustion gas.
