1. A system for aerodynamically coupling air flow from a centrifugal compressor to an axial combustor, the compressor and combustor disposed about a longitudinal axis, the system comprising:
a diffuser having an inlet, an outlet and a flow path extending therebetween, the diffuser inlet in flow communication with the centrifugal compressor, and the diffuser flow path extending radially outward from the longitudinal axis;
a deswirl assembly having an inlet, an outlet and a flow path extending therebetween, the deswirl assembly inlet in flow communication with the diffuser outlet to receive air flowing in a radially outward direction, and the deswirl assembly flow path configured to redirect the air in a radially inward and axial direction through the deswirl assembly outlet at an angle toward the longitudinal axis;
a combustor inner annular liner disposed about the longitudinal axis, the inner annular liner having an upstream end;
a combustor outer annular liner disposed concentric to the combustor inner annular liner and forming a combustion plenum therebetween, the outer annular liner having an upstream end;
a combustor dome coupled to and extending between the combustor inner and outer annular liner upstream ends; and
a curved annular plate coupled to the combustor inner and outer annular liner upstream ends to form a combustor subplenum therebetween, the curved annular plate having a first opening and a second opening formed therein, the first opening aligned with the deswirl assembly outlet to receive air discharged therefrom.
