A double annular combustor is provided with a main stage section disposed on the radially outer side such that its length is thereby minimized to reduce the resulting NOX emissions and its profile is thereby linearized so as to reduce the impingement of hot gases against the combustor wall. The pilot stage section is located radially inward so that its increased length tends to increase the residence time for idle and thereby reduce the hydrocarbon and carbon monoxide emissions.
