Air and fuel delivery system for a post combustor burning ring

The device has distributing cases housed in sectors (38) of a spray ring (26), where air is supplied to the cases through one of their ends extending inside an afterburner flame holder arm (14). The device is housed inside the arm, and extends between the spray ring and an external wheel case of an afterburner inside the arm. Each case has an air inlet opening formed by cutting an end of the sectors.
