An experimental investigation on the development of a pilot ignition system, using a novel flame ball method, has been successfully carried out for GTRE's Kaveri engine afterburner. The flame ball concept was proved in the specially set-up elemental test facility, which had high altitude simulation capability. Detailed ignition tests incorporating the newly developed pilot ignition system was carried out, under simulated conditions, in the elemental test facility and in the specially set-up full-scale Kaveri engine afterburner facility. Recommendations were made on teh dimensions, location and the type of fuel injector to be used in the pilot ignition system. The pilot ignition system has been successfully developed and tested under full-scale conditions at Bangalore
