Afterburner flameholder ion probe

摘要

An ion/electrostatic probe for an afterburning gas turbine jet engine comprises an afterburner flameholder (24) electrically insulated from other engine parts by means of non-electrically-conductive support rods (30, 45) or by means of electrically conductive rods (30) insulated (50, 52) from the engine case (12). An electrical connection (54) may be brought through the engine case. The flameholder (24) may be insulated (70) from an attached igniter.
