Abstract: An optical flame detector is provided, suitable for sensing by sensing module (1) flame-out in the afterburner of a gas turbine aircraft engine. A phosphor (9) senses the UV radiation emanating from the flame, and in response thereto emits radiation in the visible region. The visible radiation is sensed by detector module (2); its absence is used to trigger fuel flow shut-off to the afterburner.
