Emissions from and within an Allison J-33 Combustor

Abstract
Gas temperature, carbon monoxide, and nitric oxide concentration profiles measured as a function of axial and radial position inside an Allison J-33 combustor with unheated inlet air are reported. In addition, the isolated effects of combustor pressure, overall equivalence ratio, and air flow rate on combustor exit plane emissions are investigated. A consistent model of the combustion process in this combustor is presented on the basis of the results.
