An afterburner fuel injection system is disclosed which utilizes a plurality of individual fuel injectors displayed in a radial array around the periphery of a turbojet afterburner. An atomizing chamber is associated with each fuel injection conduit to achieve a homogeneous atomization of the fuel with the exhaust gases passing through the afterburner. Each fuel injector is individually connected to a fuel supply source and a source of purging air to minimize the delay in afterburner ignition and to prevent coking of the injector nozzles.

Afterburner fuel injection system

An annular burner has an annular flame stabilizer of substantially V shaped cross-section containing a circular fuel injection manifold discharging in counterflow. The annular flame stabilizer is formed by two independent parts, each of these parts constituting one blade of the V cross-section. Pivotal support means are provided at the end of the separation wall of the flows in order to mount each of the parts of the annular stabilizer. The injection manifold is secured to the outer blade of the ring.
