Abstract

A combustor (56) including: a combustor case (100) defining a plurality of case apertures (105A, 105B); a liner (110) within the combustor case (100) defining a combustion zone (120) and liner apertures (200A, 200B, 200C) through which an airflow flows into the combustion zone (120); a fuel injector (170) having a fuel channel (180) extending through a first case aperture (105A) and the liner (110), and the fuel channel (180) has a nozzle (190) at the combustion zone (120) through which fuel is injected; an igniter (210) for igniting the combustible mixture of fuel and airflow and providing a flame at the nozzle (190); and a flame sensor (220) including: a radio frequency transponder (230), comprising a transmitter-receiver pair, located exterior to the combustor case (100); a horn antenna (250) disposed in the fuel nozzle (190), and a tubular waveguide (240) extending from the radio frequency transponder (230) to the horn (250) via one of the plurality of case apertures (105A, 105B), wherein the flame sensor (220) is configured to perform flame and flow field diagnostics.
