Abstract: A chemiluminescence imaging system that may be used for monitoring a combustor flame of a gas turbine engine includes a sensor array having a plurality of pixels operable to capture an image. A multispectral mask array and an attenuation filer array of the system may be generally placed in front of the sensor array and each have a plurality of cells that are generally align, respectively, to the plurality of pixels. Each cell is generally one of a plurality of band-pass filter types distributed randomly across the multispectral mask array and an image reconstruction algorithm is used to produce at least one image for evaluating properties of the flame.

Abstract: A combustor assembly for a gas turbine engine according to an example of the present disclosure includes, among other things, a combustion chamber, and a fuel injector assembly in communication with the combustion chamber that has a swirler body situated about a nozzle to define an injector passage that converges to a throat. The throat is defined at a distance from the combustion chamber. The nozzle includes a primary fuel injector along a first fuel injector axis and at least one secondary plain jet fuel injector axially forward of the primary fuel injector.
